implement strict channel priority (libsolv PR:\n  <https://github.com/openSUSE/libsolv/pull/459>) @adriendelsalle\n  - Note that this changes the meaning of strict and flexible priority as the\n    previous implementation did not follow conda's semantics. Mamba now has\n    three modes, just like conda: strict, flexible and disabled. Strict will\n    completely disregard any packages from lower-priority channels if a\n    package of the same name exists in a higher priority channel. Flexible\n    will use packages from lower-priority channels if necessary to fulfill\n    dependencies or explicitly requested (e.g. by version number). Disabled\n    will use the highest version number, irregardless of the channel order.\n- allow subdir selection as part of the channel: users can now specify an\n  explicit list of subdirs, for example:\n\n      `-c mychannel[linux-static64, linux-64, noarch]`\n\n  to pull in repodata and packages from these three subdirs.\n  Thanks for the contribution, @afranchuk! #1033\n\nNew

for instance:\n\n```bash\nmicromamba create -n my-env -f conda-lock.yml\n```\n\n### setup-micromamba (setup-miniconda replacement)\n\n[setup-micromamba](https://github.com/marketplace/actions/setup-micromamba) is a replacement for [setup-miniconda](https://github.com/marketplace/actions/setup-miniconda) that uses `micromamba`.\n\nIt can significantly reduce your CI setup time by:\n\n- Using `micromamba`, which takes around 1 s to install.\n- Caching package downloads.\n- Caching entire `conda` environments.\n\n## Differences with `conda`\n\nWhile `mamba` and `micromamba` are generally a drop-in replacement for `conda` there are some differences:\n\n- `mamba` and `micromamba` normalize `MatchSpec` strings to the simplest form, whereas `conda` use a more verbose form\n  This can lead to slight differences in the output of `conda env export` and `mamba env export`.\n\n## Development installation\n\nPlease refer to the instructions given by the [official documentation](https://mamba.readthedocs.io/en/latest/developer_zone/dev_environment.html).\n\n## API and ABI stability\n\nThe Mamba project uses [semantic versioning](https://semver.org/) of the form `MAJOR.MINOR.PATCH`.\nWhile we try to keep things stable for users, we also need to make breaking changes to improve\nMamba and reduce technical debt.\nFuture versions of Mamba may give stronger guarantees.\n\n### `libmamba` (C++)\n\nWe are not aware of consumers of the C++ API, so we give ourselves room for improvements.\nFor `libmamba`, the term _backward compatible_ is understood as follows:\n\n- _ABI backward compatible_ means that you can replace the library binary files without recompiling\n  your code with the updated headers.\n  The observed behavior will be the same, except for bugs (disappearing, hopefully) and performance.\n- _API backward compatible_ means that you must recompile your code with the new library\n  version code, but you won't need to change your code, just re-build it.\n  This applies as long as you did not use any declaration understood to be private, for instance\n  in the `detail` sub-namespaces.\n  The observed behavior will be the same, except for bugs (disappearing, hopefully) and performance.\n  When declarations are deprecated but not removed and still functional, we consider it also\n  backward compatible, as only the observed behavior during compilation changes.\n\nWith this in mind, `libmamba` offers the following guarantees:\n\n- `PATCH` releases are API and ABI backward compatible;\n- `MINOR` releases are API compatible for declarations in `mamba/api`,\n  They can break API elsewhere and ABI anywhere;\n- `MAJOR` releases make no guarantees.\n\n### `libmambapy` (Python)\n\nFor `libmambapy`, the term _API backward compatible_ implies that your Python code will work the\nsame for a newer version of `libmambapy` as long as you did not use any declaration understood to\nbe private, for instance accessed with a name starting with an `_`.\nThe observed behavior will be the same, except for bugs (disappearing, hopefully) and performance.\nWhen declarations are deprecated but not removed and still functional, we consider it also\nbackward compatible, as the behavior is only observable when activating Python\n`DeprecationWarning`, which is usually only activated in development.\n\nWith this in mind, `libmambapy` offers the following guarantees:\n\n- `PATCH` releases are API backward compatible;\n- `MINOR` releases are API backward compatible;\n- `MAJOR` releases make no guarantees.\n\n### `mamba` and `micromamba` (executables)\n\nFor executables, the term _backward compatible_ applies to programmable inputs and outputs and means\nthat your code (including shell scripts) will work with newer versions of the executable without\nmodifications.\nProgrammable inputs/outputs include executable name, command line arguments, configuration files,\nenvironment variables, JSON command line outputs, and files created.\nIt _excludes_ human-readable output and error messages, and thus deprecation warnings written\nin the human-readable output.\n\nWith this in mind, `mamba` and `micromamba` offer the following guarantees:\n\n- `PATCH` releases are backward compatible;\n- `MINOR` releases are backward compatible;\n- `MAJOR` releases make no guarantees.\n\n## Support us\n\nOnly `mamba` and `micromamba` 2.0 and later are supported and are actively developed.\n\nThe `1.x` branch is only maintained for addressing security issues such as CVEs.\n\nFor questions, you can also join us on the [Conda Zulip](https://conda.zulipchat.com/#narrow/channel/457607-general) (note that this project is not officially affiliated with `conda` or Anaconda Inc.).\n\n## License\n\nWe use a shared copyright model that enables all contributors to maintain the copyright on their contributions.\n\nThis software is licensed under the BSD-3-Clause license. See the [LICENSE](LICENSE) file for details.\n\n---\n\n### Biweekly Dev Meeting\n\nWe have videoconference meetings every two weeks where we discuss what we have been working on and get feedback from one another.\n\nAnyone is welcome to attend, if they would like to discuss a topic or just listen in.\n\n- When: Tuesday [4:00 PM CET (Europe)](https://calendar.google.com/calendar/u/0/embed?src=ab3jrfpede0kq0ubsroe82cd00@group.calendar.google.com&ctz=Europe/Paris)\n- Where: [Mamba jitsi](https://meet.jit.si/mamba-org)\n- What: [Meeting notes](https://hackmd.io/@guj2k_aBSSyr1YHBG9raWw/HyHt-Ekzj)\n"

There is no need to perform additional checks on each file.\n"

That means, there is no copy of the file created. This saves a considerable amount of disk-space when re-using the same package in multiple environments.\n\nHowever, sometimes a text-replacement is necessary. This is the case when a file contains a reference to the prefix. On Unix systems a very long prefix is used during build (you might have seen something like ``_h_123123_placeholder_placeholder_placeholder...``). This very long prefix is stored in the metadata of the package. When a file contains this prefix, the file is copied into the target prefix and the prefix it is replaced. In text files, this is done via a simple string replacement, and in binary files the string is padded with ``\\0`` bytes (to keep the same total length of the file). Binary replacement on Windows is usually not necessary because dynamic library loading on Windows follows different rules.\n\nWhen installing a ``noarch: python`` package, the installation process will compile all ``.py``-files into Python bytecode (``.pyc``) files.\n\nAll installed files are later referenced in the ``$TARGET_PREFIX/conda-meta/mypkg-version-build.json`` file, to facilitate the removal (e.g. when upgrading or removing a package).\n\nIf the package contains a ``menu/*.json`` entry that follows the spec introduced by ``menuinst``, a start-menu entry is created on Windows. This is currently not implemented on Linux or macOS but that might change in the future.\n"

    "content": ".. _more_concepts:\n\nMore concepts\n=============\n\nOverview\n--------\n\n| This section complements :ref:`concepts<concepts>` with advanced terminology.\n\nWhile not necessary to understand the basic usage, those ``advanced concepts`` are fundamental to understand Mamba in details.\n\n\n.. _repo:\n\nPackages repository\n-------------------\n\n| A packages repository, also called ``repo``, is a generic way to describe a storage location for software packages.\n\nIn the Mamba's context, it may points to a packages server, a :ref:`channel<channel>` or a :ref:`subdir<subdir>`.\n\n\n.. _channel:\n\nChannel\n-------\n\n| A ``channel`` is an independent and isolated :ref:`repo<repo>` structure that is used to classify and administrate more easily a packages server.\n\n.. note::\n  A packages server may host one or multiple ``channels``.\n\n\n.. _subdir:\n\nSubdir\n------\n\n| A ``subdir`` is a :ref:`channel<channel>` subdirectory specific to a given operating system/platform pair.\n\nMamba is a general purpose, language agnostic package manager. The ``subdir`` structure is a convenient way to provide and access packages depending on the targeted os and platform.\n\nTypically ``linux-64``, ``osx-arm64`` or ``win-64`` but not limited to those ones.\n\nA ``subdir`` provides the packages tarballs alongside a :ref:`packages index<repodata>` including additional metadata.\n\n.. note::\n  In most cases, both ``noarch`` and ``<os>-<platform>`` subdirs are used for an operation requiring data from the :ref:`repo<repo>`\n\n\n.. _repodata:\n\nPackages index\n--------------\n\n| A repository package index is a file containing metadata about all the packages tarballs served by a :ref:`repo<repo>`.\n\n.. note::\n  Those metadata include license, file size, checksums, etc.\n\nIn Mamba, it is more often called a ``repodata`` in reference to the index filename ``repodata.json``.\n\nA ``repodata`` is specific to a :ref:`channel subdirectory<subdir>`.\n\n\n.. _tarball:\n\nPackage tarball\n---------------\n\n| A tarball is a single archive file, compressed or not, that expands to multiples files/directories. It is typically a ``zip`` file or so.\n\nIn the case of Mamba, 2 ``conda`` formats are used as package tarball:\n\n- ``tar.bz2`` is the historical formats: a ``tar`` file/ball that has been compressed using ``bzip2`` algorithm\n- ``conda`` more recent format that allows faster access to packages metadata\n\n\n.. _linking:\n\nLinking\n-------\n\nEach package contains its files index, used at a step called ``linking``.\nThe ``linking`` consists in creating a *link* between the package cache where the tarballs are expanded into multiple directories/files and the installation :ref:`target prefix<prefix>`.\n\nThe 3 kinds of *links* are:\n\n- :ref:`hard-link<hard_link>`\n- :ref:`soft-link<soft_link>`\n- :ref:`copy<copy>`\n\n\n| The default behavior is to use ``hard-links`` and fallback to ``copy``.\n\nThe advanced user may want to change that behavior using configuration (see the relevant CLI or API reference for more details):\n\n- allow ``soft-links`` to be used as a preferred fallback to ``copy`` (try to ``copy`` if ``soft-link`` fails)\n- use ``soft-links`` instead of ``hard-links`` as default behavior (``copy`` is still a fallback)\n- always ``copy`` instead of ``hard-links`` as default behavior (no fallback then)\n\n.. warning::\n   ``soft-links`` more easily lead to broken environment due to their property of becoming invalid when the target is deleted/moved\n\n\n.. _hard_link:\n\nHard-link\n*********\n\n| A ``hard-link`` is the relation between a name/path and the actual file located on the file system.\n| It is often used to describe additional ``hard-links`` pointed the same file, but the ownership of the file is shared across all those links (equivalent to a C++ shared pointer):\n\n- a reference counter is incremented when creating a new ``hard-link``, decremented when deleting one\n- the file system location is freed only when that counter decreases to 0\n\n.. image:: hard_links.png\n  :height: 300\n  :align: center\n\nsource: `Wikipedia <https://en.wikipedia.org/wiki/Hard_link>`_\n\n\nThis is the most efficient way to link:\n\n- the underlying file on the file system is not duplicated\n\n  - it is super efficient and resource friendly\n\n- ``hard-link`` stays valid when another ``hard-link`` to the same reference is deleted/moved\n\nThere are some limitations to use ``hard-links``:\n\n- not all file systems support ``hard-links``\n- ``hard-links`` don't work across file systems/partitions\n\n\n.. _soft_link:\n\nSoft-link\n*********\n\n| A ``soft-link``, also called ``symlink`` (symbolic link), is much more similar to a shortcut or a redirection to another name.\n\nIt is as efficient as a ``hard-link`` but has different properties:\n\n- works across a filesystem/partition boundaries\n- becomes invalid then the pointed name is deleted or moved (no shared ownership)\n\n\n.. _copy:\n\nCopy\n****\n\n| This is a most well-known link, a simple copy of the file is done.\n\nIt is not efficient nor resource friendly but preserve the file from deletion/modification of the reference.\n"

    "path": "docs/source/advanced_usage/package_resolution.rst",
    "content": "Package resolution\n==================\n\nTo resolve packages, mamba uses the `libsolv <https://github.com/openSUSE/libsolv>`_ library.\nLibsolv employs a \"backtracking\" satisfiability (SAT) solver to make sure that each requested spec and the dependencies are properly satisfied.\n\nIt is possible to inspect the package resolution process by adding ``-vvv`` on the command line (which activates the triple-\"verbose\" mode). In this mode, curl and libsolv will print additional information.\n\n.. note::\n\tThis documentation talks about \"track_feature\". Track features are a \"deprecated\" conda feature that are still used solely to \"down-weight\" variant packages. Conda tries to \"globally minimize\" the amount of track_features in an environment. In mamba, we don't implement the same global optimization but we do de-prioritize track features. If you want to properly de-prioritize packages with mamba, please make sure to add the track_feature in the variant package or at least as a first-order dependency (e.g. numpy-1.20-pypy should either have a track feature or a specific dependency to ``python 3.8 *pypy`` which then in turn should have the track_feature).\n\nThe package resolution basically filters, sorts and selects packages until a working solution is found.\n\nThe pruning and sorting works as follows (implemented in ``policy.c`` in libsolv):\n\n**solver_prune_to_highest_prio**\n\n- if strict channel priority is activated, we prune (filter) packages not belonging to the highest prio channel\n- if a solvable is installed, it is sorted to the front and preferred\n\n**prune_to_best_version_conda**\n\n- we first sort by track_feature: if a package has a track_feature, it's sorted to the bottom\n- next we sort by version -- highest versions first (in libsolv, a version string is called ``evr`` which stands for epoch/version/release)\n- then we sort by the sub-priority of the repository, preferring the repo with higher sub-priority\n- next we compare the build number\n\nNow, if multiple packages with the same build number are found, libsolv will create \"variant\" branches. The variants are also sorted, according to the following:\n\n**sort_by_best_dependencies**\n\n- first it's checked if the variant packages have different dependencies. For example, there can be one variant package that's built for ``python >=3.7,<3.8`` and one for ``python >=3.8,<3.9``.\n- if we find different requirements, we check if one selection **only selects packages with a track_feature** (this would be the case with a match spec like ``python 3.8.* *pypy``). In this case, we de-prioritize that variant\n- if there is no difference in track features in the dependencies, we want to prefer the variant for the higher dependency (python 3.8 in this case). To do this, we find all matching packages for ``python >=3.7,<3.8`` and ``python >=3.8,<3.9`` and check which of the two specs selects the higher version\n- if we still find no difference, we compare the timestamps of the two packages and prefer the package that was added later to the repository\n\n\nExamples\n--------\n\n**Simple example:**\n\nTo give some example orderings, we could look at the python package.\nIn conda-forge, we'd find something like\n\n- python 3.9.2 HASH_cpython [build number: 1]\n- python 3.9.2 HASH_cpython [build number: 0]\n- python 3.9.1 HASH_cpython\n- python 3.8 HASH_cpython\n- python 3.7 HASH_cpython\n- python 3.7 HASH_pypy [track_feature: pypy]\n\nIf we want to plainly install \"python\", we would prefer python 3.9.2 with build number 1 since it has the highest version and build number.\n\nIf we want to install ``python 3.7.*`` we would prefer ``python 3.7 HASH_cpython`` since it does not come with a track_feature.\n\n**More difficult example:**\n\nOn conda-forge, we're building \"variant packages\" for numpy (and other packages requiring the C API of Python). This means for a given version of numpy, we'll end up with ~5 almost equivalent variant packages, for cpython 3.6, 3.7 and 3.8 as well as pypy 3.6 and 3.7.\nFor this example the default is the cpython build of numpy. However, currently conda-forge does not apply the down-weigthing via track_feature on the terminal node (numpy), but only in some dependency package (such as python).\n\nFor the case where we want to simply install ``numpy``, we need to find which numpy variant installs the highest python package. In this case libsolv would decide for ``numpy-1.20-cpython38``.\n\nIf we install ``numpy python=3.7`` we have two potential variants: ``numpy-1.20-cpython37`` and ``numpy-1.20-pypy37``. In this case we need to inspect whether one of those two builds will require exclusively packages with a track_feature applied. And indeed, the ``pypy37`` package will have a requirement on ``python_abi 3.7 *pypy`` and **all** packages matching this requirement have a track_feature, so that it will be down-weighted.\n"

TODO high-level summary of new features:\n.. - OCI registries\n.. - Mirrors\n.. - Own implementation repodata.json\n\n\nCommand Line Executables\n------------------------\nMamba (executable)\n******************\n\n``mamba``, previously a Python executable mixing ``libmambapy``, ``conda``, and some specific code logic\nhas been entirely replaced by the dynamically linked version of ``micromamba``,\na statically-linked ELF based on ``libmamba``.\n\nHence ``mamba`` now has the exact same user interface and experience as ``micromamba``.\n\n.. warning::\n\n   The previous code being a highly complex project with few of its original developers still\n   active, it is hard to make an exhaustive list of all changes.\n\n   Please help us by reporting changes missing changes.\n\nMicromamba\n**********\nMicromamba receives all new features and its CLI remains mostly unchanged.\n\nBreaking changes include:\n\n- ``micromamba shell init`` root prefix parameter ``--prefix`` (``-p``) was renamed\n  ``--root-prefix`` (``-r``).\n  Both options were supported in version ``1.5``.\n- A new config ``order_solver_request`` (default true) can be used to order the dependencies passed\n  to the solver, getting order independent solutions.\n- Support for complex match specs such as ``pkg[md5=0000000000000]`` and ``pkg[build='^\\d*$']``.\n- **For ``micromamba<=2.1.0``:** Lost support for leading and internal globs in\n  version strings (via redesigned ``VersionSpec``, which no longer handles\n  version strings as a regex). Only trailing globs were supported.\n- Full version regexes, such as ``^3.3+$``, are not implemented.\n\n.. TODO OCI and mirrors\n\n\nLibraries\n---------\nMamba (Python package)\n**********************\nIn version 2.0, all tools are fully written in C++.\nAll code previously available in Python through ``import mamba`` has been removed.\n\nLibmambapy (Python bindings)\n****************************\nThe Python bindings to the C++ ``libmamba`` library remain available through ``import libmambapy``.\nThey are now considered the first class citizen to using Mamba in Python.\nChanges include:\n\n- The global ``Context``, previously available through ``Context()``, must now be instantiated at least\n  once before using ``libmambapy`` functions and types. Only one instance can exist at any time,\n  but that instance can be destroyed and another recreated later, for example if you use it in\n  specific functions scopes.\n\n  What's more, it is required to be passed explicitly in a few more functions. Notably:\n    - ``MultiPackageCache`` (constructor)\n    - ``SubdirData.create_repo``\n    - ``SubdirIndex.create``\n    - ``SubdirIndex.download``\n    - ``clean``\n    - ``transmute``\n    - ``get_virtual_packages``\n    - ``cancel_json_output``\n\n  In version 2, ``Context()`` will throw an exception to allow catching errors more smoothly.\n\n- ``ChannelContext`` is no longer an implicit global variable.\n  It must be constructed with one of ``ChannelContext.make_simple`` or\n  ``ChannelContext.make_conda_compatible`` (with ``Context.instance`` as argument in most cases)\n  and passed explicitly to a few functions.\n- A new ``Context`` independent submodule ``libmambapy.specs`` has been introduced with:\n\n  - The redesign of the ``Channel`` and a new ``UnresolvedChannel`` used to describe unresolved\n    channel strings.\n    A featureful ``libmambapy.specs.CondaURL`` is used to describe channel URLs.\n  - The redesign of ``MatchSpec``.\n    The module also includes a platform enumeration, an implementation of ordered ``Version``,\n    and a ``VersionSpec`` to match versions.\n    **Breaking change (for ``libmambapy<=2.1.0``):** ``VersionSpec`` lost support for\n    leading and internal globs in version strings because they are no longer\n    handled as a regex. Only trailing globs were supported.\n  - Full version regexes, such as ``^3.3+$``, are not implemented in ``VersionSpec`` and\n    ``MatchSpec``.\n  - ``PackageInfo`` has been moved to this submodule.\n    Some attributes have been given a more explicit name ``fn`` > ``filename``,\n    ``url`` > ``package_url``.\n\n- A new ``Context`` independent submodule ``libmambapy.solver`` has been introduced with the\n  changes below.\n  A usage documentation page is available at :ref:`mamba_usage_solver`.\n\n  - The redesign of the ``Pool``, which is now available as ``libmambapy.solver.libsolv.Database``.\n    The new interfaces make it easier to create repositories without using other ``libmambapy``\n    objects.\n  - ``Repo`` has been redesigned into a lightweight ``RepoInfo`` and moved to\n    ``libmambapy.solver.libsolv``.\n    The creation and modification of repos happen through the ``Database``, with methods such as\n    ``Database.add_repo_from_repodata_json`` and ``Database.add_repo_from_packages``, but also\n    high-level free functions such as ``load_subdir_in_database`` and\n    ``load_installed_packages_in_database``.\n  - The ``Solver`` has been moved to ``libmambapy.solver.libsolv.Solver``.\n\n    - All jobs, pins, and flags must be passed as a single ``libmambapy.solver.Request``.\n    - The outcome of solving the request is either a ``libmambapy.solver.Solution`` or a\n      ``libmambapy.solver.libsolv.Unsolvable`` state from which rich error messages can be\n      extracted.\n\nFor many changes, an exception throwing placeholders has been kept to advise developers on the new\ndirection to take.\n\nLibmamba (C++)\n**************\nThe C++ library ``libmamba`` has received significant changes.\nDue to the low usage of the C++ interface, all changes are not listed here.\nThe main changes are:\n\n- Refactoring and testing of a large number of utilities into a ``util::`` namespace.\n- Creation of ``specs::`` including the items below.\n  A usage documentation (in Python) is available at :ref:`mamba_usage_specs`.\n\n  - Implementations of ``Version`` and ``VersionSpec`` for matching versions,\n  - A refactoring of a purely functional ``Channel`` class,\n  - Implementation of a ``UnresolvedChannel`` to describe unresolved ``Channels``,\n  - A refactored and complete implementation of ``MatchSpec`` using the components above.\n  - **Breaking change (for ``libmamba<=2.1.0``):** ``VersionSpec`` lost support for\n    leading and internal globs in version strings because they are no longer\n    handled as a regex. Only trailing globs were supported. This\n    affects version strings in both the command-line interface and recipe\n    requirements.\n  - Full version regexes, such as ``^3.3+$``, are not implemented in ``VersionSpec`` and\n    ``MatchSpec``.\n\n- A cleanup of ``ChannelContext`` to be a light proxy and parameter holder wrapping the\n  ``specs::Channel``.\n- A new ``repodata.json`` parser using `simdjson <https://simdjson.org/>`_.\n- The ``MPool``, ``MRepo`` and ``MSolver`` API has been completely redesigned into a ``solver``\n  subnamespace and works independently of the ``Context``.\n  The ``solver::libsolv`` sub-namespace has also been added for full isolation of libsolv, and a\n  solver API without ``Context``.\n  The ``solver`` API redesign includes the items below.\n  A usage documentation (in Python) is available at :ref:`mamba_usage_solver`.\n\n  - A refactoring of the ``MPool`` as a ``DataBase``, fully isolates libsolv, and simplifies\n    repository creation.\n  - A refactoring and thinning of ``MRepo`` as a new ``RepoInfo``.\n  - A solver ``Request`` with all requirements to solve is the new way to specify jobs.\n  - A refactoring of ``Solver``.\n  - A solver outcome as either a ``Solution`` or an ``UnSolvable`` state.\n\n- Plug of the Mamba's ``MatchSpec`` implementation in the ``Solver``, enabling the solving of all\n  types of previously unsupported MatchSpecs.\n\n- Improved downloaders.\n\nMirrors and OCI registries\n--------------------------\nIn the perspective of ensuring continuous and faster access when downloading packages, we now support mirroring channels.\n\nFurthermore, we support fetching packages from `OCI registries <https://github.com/opencontainers/distribution-spec/blob/v1.0/spec.md#definitions>`_\nin order to provide an alternative to hosting on https://conda.anaconda.org/conda-forge/.\n\nSpecifying a mirror can be done in the rc file as follows:\n\n.. code::\n\n  $ cat ~/.mambarc\n\n  # Specify a mirror (can be a list of mirrors) for conda-forge channel\n  mirrored_channels:\n    conda-forge: [\"oci://ghcr.io/channel-mirrors/conda-forge\"]\n\n  # ``repodata_use_zst`` isn't considered when fetching from oci registries\n  # since compressed repodata is handled internally\n  # (if present, compressed repodata is necessarily fetched)\n  # Setting ``repodata_use_zst`` to ``false`` avoids useless requests with\n  # zst extension in repodata filename\n  repodata_use_zst: false\n\nThen, you can for instance create a new environment ``pandoc_from_oci`` where ``pandoc`` can be fetched from the specified mirror and installed:\n\n.. code::\n\n  $ micromamba create -n pandoc_from_oci pandoc -c conda-forge\n\nListing packages in the created ``pandoc_from_oci`` environment:\n\n.. code::\n\n  $ micromamba list -n pandoc_from_oci\n\n  Name    Version  Build       Channel\n  ──────────────────────────────────────────\n  pandoc  3.2      ha770c72_0  conda-forge\n"

    "content": "Internals of mamba\n==================\n\nMamba comes with a C++ core (for speed and efficiency), and a clean Python API on top.

But it will only returns the ``Reldep`` 's ``name``\n\nOffsets\n#######\n\nAn ``Offset`` represents a positive or negative shift of a pointer on an array.\n\nFor example, a *solvable* does not contain all its data but rather holds multiple offsets on its ``repo->idarraydata`` storage.\n\n- ``idarraydata`` is an ``Id`` pointer\n- ``provides``, ``requires``, etc. are offsets in ``idarraydata``\n\nwhatprovides\n************\n\nA ``provider`` is a *solvable* fulfilling a *specification*. The following definitions are key to disambiguate how ``libsolv`` works:\n\n- a *package* is an identification of the resource handled: a name such as ``xtensor``\n\n- a *solvable* is a specific version of the *package*. It can be assimilated to its tarball.\n\n  - in ``Mamba``, a *solvable* name MUST match the package name\n  - ``libsolv`` handles cases where *solvables* are providing different entities than what identified in their names (example: ``pynum`` providing ``numpy``)\n\n    - this is not used, but important to know to understand the terminology\n\n- a *specification*: an expression to match *solvables* providing the same *package*\n\n  - the package name can be used to select all providers/*solvables*\n  - a more specific *spec* like ``s2=\"xtensor>=0.20\"`` will only match a subset of *solvables*: the ones that have version >=0.20 (whatever the build string)\n\nLet's take a simple example to recap:\n\n- the package: ``xtensor``\n- solvable(s):\n\n  - ``xtensor=0.20.10=hc9558a2_0``\n  - ``xtensor=0.23.10=h4bd325d_0``\n  - etc.\n\n- specification(s):\n\n  - ``xtensor``\n  - ``xtensor>=0.20``\n  - etc.\n\n.. note::\n   It's possible that a *package* is not provided by any *solvable*.

They are triggered during a phase called ``propagation`` after decisions taken on previous rules for some solvable.\n\nThe possible decisions on solvables are ``installation`` or ``removal``/``conflict``, this is stored as resp. positive and negative Ids.\n\nRelated rules are then evaluated during another level of decision: those are the one with an opposite first literal.\n\nExample:\n\n- the install spec is to install ``p1`` provided by a single solvable ``s1``: ``r1=(s1)``\n- ``s1`` depends on spec ``p2``, provided by ``s21`` or ``s22``: ``r2=(-s1|s21|s22)``\n- decision to install ``s1`` triggers rule ``r2``\n\nTransaction\n***********\n\nAnother important part of libsolv is the ``Transaction``. A transaction governs what packages are installed or removed, and a transaction is the result of a successful solve process.\n\nA transaction in libsolv is a single list (Queue) of Solvable ``Id's`` and is thus rather simple. The Queue contains either a positive or negative ``Id``. Each negative ``Id`` is ``uninstalled`` from the environment, and each positive ``Id`` is to be ``installed``. libsolv classifies the entire range of Id's into different types of transaction operations. For example, if we have ``{ -5, 5 }`` that would be a reinstall transaction for the Solvable with ``Id == 5``.\nIf the ``Id's`` are different then it can be a downgrade or upgrade operation (first, the previous package needs removal before the higher or lower version can be installed). The ``transaction_classify`` and ``transaction_classify_pkgs`` functions of libsolv take care of this classification to present a nice output to the user.\n\nAnother crucial libsolv function is ``transaction_order`` to order the transaction in a way that they are installed with the lowest dependency first (topological sort). This ensures that e.g. ``python`` is installed before any packages depending on ``python`` as they are sometimes needed during installation (for example for ``noarch`` packages with ``entry_points``).\n\nLastly, we can force installation or explicitly install from URL's by crafting transactions without using the solver – just by adding the correct ``Id's`` into the Transaction queue.\n"

Remove shell initialization\n   ^^^^^^^^^^^^^^^^^^^^^^^^^^^\n\n   If you initialized your shell with ``mamba shell init``, you need to remove the initialization code from your shell configuration files.\n   Run the following command for each shell you initialized:\n\n   .. code-block:: bash\n\n      mamba shell deinit -s bash    # for bash\n      mamba shell deinit -s zsh     # for zsh\n      mamba shell deinit -s fish    # for fish\n      mamba shell deinit -s xonsh   # for xonsh\n      mamba shell deinit -s csh     # for csh/tcsh\n      mamba shell deinit -s nu      # for nushell\n\n   On Windows PowerShell:\n\n   .. code-block:: powershell\n\n      mamba shell deinit -s powershell\n\n   This will remove the mamba initialization block from your shell configuration files (``.bashrc``, ``.zshrc``, ``config.fish``, etc.).\n\n2. Remove the Miniforge installation directory and package cache\n   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n\n   The Miniforge installation directory contains ``mamba``, ``conda``, and all installed packages and environments.\n   Check ``mamba info`` to find the exact location:\n\n   - The base environment path shows the Miniforge installation directory (it's the parent of the base env)\n   - The package cache location is shown under ``package cache``\n\n   Default locations depend on your operating system:\n\n   - **Linux/macOS:** Usually ``~/miniforge3`` or ``~/mambaforge``\n   - **Windows:** Usually ``C:\\Users\\<username>\\miniforge3`` or ``C:\\Users\\<username>\\mambaforge``\n\n   .. code-block:: bash\n\n      # Linux/macOS - remove the installation directory\n      # Use the base environment path from 'mamba info' to find the exact location\n      rm -rf ~/miniforge3\n      # or\n      rm -rf ~/mambaforge\n\n      # Also remove the package cache if it's in a separate location\n      # (check the 'package cache' path from 'mamba info')\n      rm -rf ~/.cache/conda/pkgs  # or your specific cache location\n\n   On Windows PowerShell:\n\n   .. code-block:: powershell\n\n      # Use the base environment path from 'mamba info' to find the exact location\n      Remove-Item -Recurse -Force $env:USERPROFILE\\miniforge3\n      # or\n      Remove-Item -Recurse -Force $env:USERPROFILE\\mambaforge\n      # Also remove package cache if separate (check 'mamba info' for exact path)\n\n   .. warning::\n\n      This will delete the entire Miniforge installation, including all environments, installed packages, and cached data.\n      Make sure you have backed up any important environments or data before removing this directory.\n\n3. Remove configuration files (optional)\n   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n\n   Check ``mamba info`` for the exact paths to your configuration files:\n\n   - ``user config files`` shows the location of ``.mambarc``\n   - ``populated config files`` shows the location of ``.condarc``\n\n   If you want to remove these configuration files:\n\n   .. code-block:: bash\n\n      # Use the paths from 'mamba info', or default locations:\n      rm ~/.mambarc        # if it exists\n      rm ~/.condarc        # if it exists and was only used for mamba/miniforge\n\n   On Windows:\n\n   .. code-block:: powershell\n\n      # Use the paths from 'mamba info', or default locations:\n      Remove-Item $env:USERPROFILE\\.mambarc -ErrorAction SilentlyContinue\n      Remove-Item $env:USERPROFILE\\.condarc -ErrorAction SilentlyContinue\n\n   .. note::\n\n      If you also use ``conda`` from another distribution (like Anaconda), be careful not to delete shared configuration files that are still needed.\n\n4. Remove from PATH (if manually added)\n   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n\n   If you manually added Miniforge to your PATH, remove those entries from your shell configuration files (``.bashrc``, ``.zshrc``, ``.profile``, etc.).\n\nAfter completing these steps, ``mamba`` and the Miniforge distribution will be completely removed from your system.\n"

We use ``bash <(curl ...)`` instead of ``curl .. | bash`` as the latter does not work with prompts\n\n.. code:: bash\n\n   \"${SHELL}\" <(curl -L micro.mamba.pm/install.sh)\n\nFor NuShell users, run ``sh -c (curl -L micro.mamba.pm/install.sh)``.\n\nOn Windows Powershell, use\n\n.. code :: powershell\n\n   Invoke-Expression ((Invoke-WebRequest -Uri https://micro.mamba.pm/install.ps1 -UseBasicParsing).Content)\n\nA specific micromamba release can be installed by setting the ``VERSION`` environment variable.\nThe release versions contain a build number in addition to the micromamba version.\n\nMicromamba releases can be found on Github: https://github.com/mamba-org/micromamba-releases/releases\n\nSelf updates\n^^^^^^^^^^^^\nOnce installed, ``micromamba`` can be updated with\n\n.. code-block:: bash\n\n   micromamba self-update\n\nA explicit version can be specified with\n\n.. code-block:: bash\n\n   micromamba self-update --version 1.4.6\n\nManual installation\n^^^^^^^^^^^^^^^^^^^\n\n.. warning::\n\n   This is for advanced users.\n\n.. _umamba-install-posix:\n\nLinux and macOS\n~~~~~~~~~~~~~~~\n\nDownload and unzip the executable (from the official conda-forge package):\n\nEnsure that basic utilities are installed. We need ``curl`` and ``tar`` with support for ``bzip2``.\nAlso you need a glibc based system like Ubuntu, Fedora or Centos (Alpine Linux does not work natively).\n\nThe following magic URL always returns the latest available version of micromamba, and the ``bin/micromamba`` part is automatically extracted using ``tar``.\n\n.. code:: bash\n\n  # Linux Intel (x86_64):\n  curl -Ls https://micro.mamba.pm/api/micromamba/linux-64/latest | tar -xvj bin/micromamba\n  # Linux ARM64:\n  curl -Ls https://micro.mamba.pm/api/micromamba/linux-aarch64/latest | tar -xvj bin/micromamba\n  # Linux Power:\n  curl -Ls https://micro.mamba.pm/api/micromamba/linux-ppc64le/latest | tar -xvj bin/micromamba\n  # macOS Intel (x86_64):\n  curl -Ls https://micro.mamba.pm/api/micromamba/osx-64/latest | tar -xvj bin/micromamba\n  # macOS Silicon/M1 (ARM64):\n  curl -Ls https://micro.mamba.pm/api/micromamba/osx-arm64/latest | tar -xvj bin/micromamba\n\nAfter extraction is completed, we can use the micromamba binary.\n\nIf you want to quickly use micromamba in an ad-hoc usecase, you can run\n\n.. code:: bash\n\n  export MAMBA_ROOT_PREFIX=/some/prefix  # optional, defaults to ~/micromamba\n  eval \"$(./bin/micromamba shell hook -s posix)\"\n\nThis shell hook modifies your shell variables to include the micromamba command.\n\nIf you want to persist these changes, you can automatically write them to your ``.bashrc`` (or ``.zshrc``) by running ``./micromamba shell init ...``.\nThis also allows you to choose a custom MAMBA_ROOT_ENVIRONMENT, which is where the packages and repodata cache will live.\n\n.. code:: sh\n\n  # Linux/bash:\n  ./bin/micromamba shell init -s bash -r ~/micromamba  # this writes to your .bashrc file\n  # sourcing the bashrc file incorporates the changes into the running session.\n  # better yet, restart your terminal!\n  source ~/.bashrc\n\n  # macOS/zsh:\n  ./micromamba shell init -s zsh -r ~/micromamba\n  source ~/.zshrc\n\nNow you can activate the base environment and install new packages, or create other environments.\n\n.. code:: bash\n\n  micromamba activate  # this activates the base environment\n  micromamba install python=3.6 jupyter -c conda-forge\n  # or\n  micromamba create -n env_name xtensor -c conda-forge\n  micromamba activate env_name\n\nAn exclusive `conda-forge <https://conda-forge.org/>`_ setup can be configured with:\n\n.. code-block:: bash\n\n   micromamba config append channels conda-forge\n   micromamba config set channel_priority strict\n\n.. _umamba-install-win:\n\nWindows\n~~~~~~~\n\n| ``micromamba`` also has Windows support! For Windows, we recommend powershell.\n| Below are the commands to get micromamba installed in ``PowerShell``.\n\n.. code-block:: powershell\n\n  Invoke-Webrequest -URI https://micro.mamba.pm/api/micromamba/win-64/latest -OutFile micromamba.tar.bz2\n  tar xf micromamba.tar.bz2\n\n  MOVE -Force Library\\bin\\micromamba.exe micromamba.exe\n  .\\micromamba.exe --help\n\n  # You can use e.g. $HOME\\micromambaenv as your base prefix\n  $Env:MAMBA_ROOT_PREFIX=\"C:\\Your\\Root\\Prefix\"\n\n  # Invoke the hook\n  .\\micromamba.exe shell hook -s powershell | Out-String | Invoke-Expression\n\n  # ... or initialize the shell\n  .\\micromamba.exe shell init -s powershell -r C:\\Your\\Root\\Prefix\n  # and use micromamba directly\n  micromamba create -f ./test/env_win.yaml -y\n  micromamba activate yourenv\n\n\nNightly builds\n**************\n\nYou can download fully statically linked builds for each commit to ``main`` on GitHub\n(scroll to the bottom of the \"Summary\" page):\nhttps://github.com/mamba-org/mamba/actions/workflows/static_build.yml?query=is%3Asuccess\n\nDocker images\n*************\n\nThe `mambaorg/micromamba <https://hub.docker.com/r/mambaorg/micromamba>`_ docker\nimage can be used to run ``micromamba`` without installing it:\n\n.. code-block:: bash\n\n  docker run -it --rm mambaorg/micromamba:latest micromamba info\n\n\nBuild from source\n*****************\n\n.. note::\n\n   These instructions do not work currently on Windows, which requires a more complex hybrid build.\n   For up-to-date instructions on Windows and Unix, consult the scripts in the\n   `micromamba-feedstock <https://github.com/conda-forge/micromamba-feedstock>`_.\n\nTo build from source, install the development dependencies, using a Conda compatible installer\n(``conda``/``mamba``/``micromamba``/``rattler``/``pixi``).\n\n.. code-block:: bash\n\n  micromamba create -n mamba --file dev/environment-micromamba-static.yml\n  micromamba activate mamba\n\nUse CMake from this environment to drive the build:\n\n.. code-block:: bash\n\n   cmake -B build/ \\\n       -G Ninja \\\n       ${CMAKE_ARGS} \\\n       -D CMAKE_INSTALL_PREFIX=\"${CONDA_PREFIX}\" \\\n       -D CMAKE_BUILD_TYPE=\"Release\" \\\n       -D BUILD_LIBMAMBA=ON \\\n       -D BUILD_LIBMAMBA_SPDLOG=ON \\\n       -D BUILD_STATIC=ON \\\n       -D BUILD_MICROMAMBA=ON\n   cmake --build build/ --parallel\n\nYou will find the executable under \"build/micromamba/micromamba\".\nThe executable can be striped to remove its size:\n\n.. code:: bash\n\n   strip \"build/micromamba/micromamba\"\n\n.. _umamba-uninstall:\n\nUninstalling Micromamba\n************************\n\nTo completely remove ``micromamba`` from your system, follow these steps:\n\n.. note::\n\n   Before uninstalling, you can check your specific installation paths by running:\n\n   .. code-block:: bash\n\n      micromamba info\n\n   This will show you important information such as:\n\n   - ``envs directories``: where your environments are stored\n   - ``package cache``: where downloaded packages are cached\n   - ``user config files``: location of your ``.mambarc`` file\n   - ``populated config files``: location of your ``.condarc`` file\n   - ``root prefix``: the base directory for micromamba (usually shown as the first envs directory's parent)\n\n   Use these paths to adapt the commands below to your specific installation.\n\n1. Remove shell initialization\n   ^^^^^^^^^^^^^^^^^^^^^^^^^^^\n\n   If you initialized your shell with ``micromamba shell init``, you need to remove the initialization code from your shell configuration files.\n   Run the following command for each shell you initialized:\n\n   .. code-block:: bash\n\n      micromamba shell deinit -s bash    # for bash\n      micromamba shell deinit -s zsh     # for zsh\n      micromamba shell deinit -s fish    # for fish\n      micromamba shell deinit -s xonsh   # for xonsh\n      micromamba shell deinit -s csh     # for csh/tcsh\n      micromamba shell deinit -s nu      # for nushell\n\n   On Windows PowerShell:\n\n   .. code-block:: powershell\n\n      micromamba shell deinit -s powershell\n\n   This will remove the mamba initialization block from your shell configuration files (``.bashrc``, ``.zshrc``, ``config.fish``, etc.).\n\n2. Remove the micromamba executable\n   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n\n   The location of the ``micromamba`` executable depends on your installation method:\n\n   **Automatic installation script:**\n   The executable is typically installed to ``~/.local/bin/micromamba`` (Linux/macOS) or ``%LOCALAPPDATA%\\micromamba\\micromamba.exe`` (Windows).\n\n   **Homebrew (macOS):**\n   .. code-block:: bash\n\n      brew uninstall micromamba\n\n   **Manual installation:**\n   Remove the directory where you extracted or installed the ``micromamba`` executable.\n\n3. Remove the root prefix directory and package cache\n   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n\n   ``micromamba`` stores all environments, packages, and cache in specific directories.\n   Check ``micromamba info`` to find the exact locations for your installation:\n\n   - The root prefix is typically the parent directory of the first ``envs directories`` path shown\n   - The package cache location is shown under ``package cache``\n\n   By default, the root prefix is ``~/micromamba`` (Linux/macOS) or ``%USERPROFILE%\\micromamba`` (Windows).\n   If you specified a custom location with ``-r`` during initialization, use that location instead.\n\n   .. code-block:: bash\n\n      # Linux/macOS - remove the default root prefix\n      rm -rf ~/micromamba\n\n      # Or if you used a custom location (check with 'micromamba info'):\n      rm -rf /path/to/your/custom/root/prefix\n\n      # Also remove the package cache if it's in a separate location\n      # (check the 'package cache' path from 'micromamba info')\n      rm -rf ~/.cache/conda/pkgs  # or your specific cache location\n\n   On Windows PowerShell:\n\n   .. code-block:: powershell\n\n      Remove-Item -Recurse -Force $env:USERPROFILE\\micromamba\n      # Also remove package cache if separate (check 'micromamba info' for exact path)\n\n   .. warning::\n\n      This will delete all environments, installed packages, and cached data. Make sure you have backed up any important environments or data before removing this directory.\n\n4. Remove configuration files (optional)\n   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n\n   Check ``micromamba info`` for the exact paths to your configuration files:\n\n   - ``user config files`` shows the location of ``.mambarc``\n   - ``populated config files`` shows the location of ``.condarc``\n\n   If you want to remove these configuration files:\n\n   .. code-block:: bash\n\n      # Use the paths from 'micromamba info', or default locations:\n      rm ~/.mambarc        # if it exists\n      rm ~/.condarc        # if it exists and was only used for micromamba\n\n   On Windows:\n\n   .. code-block:: powershell\n\n      # Use the paths from 'micromamba info', or default locations:\n      Remove-Item $env:USERPROFILE\\.mambarc -ErrorAction SilentlyContinue\n      Remove-Item $env:USERPROFILE\\.condarc -ErrorAction SilentlyContinue\n\n   .. note::\n\n      If you also use ``conda`` or ``mamba`` (from Miniforge), be careful not to delete shared configuration files that are still needed.\n\nAfter completing these steps, ``micromamba`` will be completely removed from your system.\n"

For this reason, the generic\n   interface has not been fully completed and users need to access the submodule\n   :any:`libmambapy.solver.libsolv <mamba::solver::libsolv>` for certain types.\n\nPopulating the Package Database\n-------------------------------\nThe first thing needed is a |Database| of all the packages and their dependencies.\nPackages are organised in repositories, described by a\n:cpp:type:`RepoInfo <mamba::solver::libsolv::RepoInfo>`.\nThis serves to resolve explicit channel requirements or channel priority.\nAs such, the database constructor takes a set of\n:cpp:type:`ChannelResolveParams <mamba::specs::ChannelResolveParams>`\nto work with :cpp:type:`Channel <mamba::specs::Channel>` data\ninternally (see :ref:`the usage section on Channels <libmamba_usage_channel>` for more\ninformation).\n\nThe first way to add a repository is from a list of |PackageInfo| using\n:cpp:func:`DataBase.add_repo_from_packages <mamba::solver::libsolv::Database::add_repo_from_packages>`:\n\n.. code:: python\n\n   import libmambapy\n\n   channel_alias = libmambapy.specs.CondaURL.parse(\"https://conda.anaconda.org\")\n\n   db = libmambapy.solver.libsolv.Database(\n       libmambapy.specs.ChannelResolveParams(channel_alias=channel_alias)\n   )\n\n   repo1 = db.add_repo_from_packages(\n       packages=[\n           libmambapy.specs.PackageInfo(name=\"python\", version=\"3.8\", ...),\n           libmambapy.specs.PackageInfo(name=\"pip\", version=\"3.9\", ...),\n           ...,\n       ],\n       name=\"myrepo\",\n   )\n\nThe second way of loading packages is through Conda's repository index format ``repodata.json``\nusing\n:cpp:func:`DataBase.add_repo_from_repodata_json <mamba::solver::libsolv::Database::add_repo_from_repodata_json>`.\nThis is meant for convenience, and is not a performant alternative to the former method, since these files\ngrow large.\n\n.. code:: python\n\n   repo2 = db.add_repo_from_repodata_json(\n       path=\"path/to/repodata.json\",\n       url=\"htts://conda.anaconda.org/conda-forge/linux-64\",\n       channel_id=\"conda-forge\",\n   )\n\nOne of the repositories can be set to have a special meaning of \"installed repository\".\nIt is used as a reference point in the solver to compute changes.\nFor instance, if a package is required but is already available in the installed repo, the solving\nresult will not mention it.\nThe function\n:cpp:func:`DataBase.set_installed_repo <mamba::solver::libsolv::Database::set_installed_repo>` is\nused for that purpose.\n\n.. code:: python\n\n   db.set_installed_repo(repo1)\n\nBinary serialization of the database (Advanced)\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\nThe |Database| reporitories can be serialized in binary format for faster reloading.\nTo ensure integrity and freshness of the serialized file, metadata about the packages,\nsuch as source url and\n:cpp:type:`RepodataOrigin <mamba::solver::libsolv::RepodataOrigin>`, are stored inside the\nfile when calling\n:cpp:func:`DataBase.native_serialize_repo <mamba::solver::libsolv::Database::native_serialize_repo>` .\nUpon reading, similar parameters are expected as inputs to\n:cpp:func:`DataBase.add_repo_from_native_serialization <mamba::solver::libsolv::Database::add_repo_from_native_serialization>`.\nIf they mismatch, the loading results in an error.\n\nA typical wokflow first tries to load a repository from such binary cache, and then quietly\nfallbacks to ``repodata.json`` on failure.\n\nCreating a solving request\n--------------------------\nAll jobs that need to be resolved are added as part of a |Request|.\nThis includes installing, updating, removing packages, as well as solving cutomization parameters.\n\n.. code:: python\n\n   Request = libmambapy.solver.Request\n   MatchSpec = libmambapy.specs.MatchSpec\n\n   request = Request(\n       jobs=[\n           Request.Install(MatchSpec.parse(\"python>=3.9\")),\n           Request.Update(MatchSpec.parse(\"numpy\")),\n           Request.Remove(MatchSpec.parse(\"pandas\"), clean_dependencies=False),\n       ],\n       flags=Request.Flags(\n           allow_downgrade=True,\n           allow_uninstall=True,\n       ),\n   )\n\nSolving the request\n-------------------\nThe |Request| and the |Database| are the two input parameters needed to solve an environment.\nThis task is achieved with the :cpp:func:`Solver.solve <mamba::solver::libsolv::Solver::solve>`\nmethod.\n\n.. code:: python\n\n   solver = libmambapy.solver.libsolv.Solver()\n   outcome = solver.solve(db, request)\n\nThe outcome can be of two types, either a |Solution| listing packages (|Packageinfo|) and the\naction to take on them (install, remove...), or an |UnSolvable| type when no solution exists\n(because of conflict, missing packages...).\n\nExamine the solution\n~~~~~~~~~~~~~~~~~~~~\nWe can test if a valid solution exists by checking the type of the outcome.\nThe attribute :cpp:member:`Solution.actions <mamba::solver::Solution::actions>` contains the actions\nto take on the installed repository so that it satisfies the |Request| requirements.\n\n.. code:: python\n\n    Solution = libmambapy.solver.Solution\n\n    if isinstance(outcome, Solution):\n        for action in outcome.actions:\n            if isinstance(action, Solution.Upgrade):\n                my_upgrade(from_pkg=action.remove, to_pkg=action.install)\n            if isinstance(action, Solution.Reinstall):\n                ...\n            ...\n\nAlternatively, an easy way to compute the update to the environment is to check for ``install`` and\n``remove`` members, since they will populate the relevant fields for all actions:\n\n.. code:: python\n\n    Solution = libmambapy.solver.Solution\n\n    if isinstance(outcome, Solution):\n        for action in outcome.actions:\n            if hasattr(action, \"install\"):\n                my_download_and_install(action.install)\n            # WARN: Do not use `elif` since actions like `Upgrade`\n            # are represented as an `install` and `remove` pair.\n            if hasattr(action, \"remove\"):\n                my_delete(action.remove)\n\nUnderstand unsolvable problems\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\nWhen a problem has no |Solution|, it is inherenty hard to come up with an explanation.\nIn the easiest case, a required package is missing from the |Database|.\nIn the most complex, many package dependencies are incompatible without a single culprit.\nIn this case, packages should be rebuilt with weaker requirements, or with more build variants.\nThe |UnSolvable| class attempts to build an explanation.\n\nThe :cpp:func:`UnSolvable.problems <mamba::solver::libsolv::UnSolvable::problems>` is a list\nof problems, as defined by the solver.\nIt is not easy to understand without linking it to specific |MatchSpec| and |PackageInfo|.\nThe method\n:cpp:func:`UnSolvable.problems_graph <mamba::solver::libsolv::UnSolvable::problems_graph>`\ngives a more structured graph of package dependencies and incompatibilities.\nThis graph is the underlying mechanism used in\n:cpp:func:`UnSolvable.explain_problems <mamba::solver::libsolv::UnSolvable::explain_problems>`\nto build a detail unsolvability message.\n"

By default, it will hide all credentials\n\n.. code:: python\n\n   import libmambapy.specs as specs\n\n   url = specs.CondaURL.parse(\"mamba.pm/conda-forge\")\n   url.set_user(\"user@mail.com\")\n   url.set_password(\"private\")\n   url.set_token(\"xy-12345678-1234\")\n\n   assert url.str() == \"https://user%40mail.com:*****@mamba.pm/t/*****\"\n   assert (\n       url.str(credentials=\"Show\")\n       == \"https://user%40mail.com:private@mamba.pm/t/xy-12345678-1234\"\n   )\n   assert url.str(credentials=\"Remove\") == \"https://mamba.pm/\"\n\nSimilarly the :cpp:func:`CondaURL.pretty_str <mamba::specs::CondaURL::pretty_str>` returns a more\nuser-friendly string, but that may not be parsed back.\n\n\nUnresolvedChannel\n-----------------\n\nA |UnresolvedChannel| is a lightweight object to represent a channel string, as in passed in\nthe CLI or configuration.\nSince channels rely heavily on configuration options, this type can be used as a placeholder for a\nchannel that has not been fully \"resolved\" to a specific location.\nIt does minimal parsing and can detect the type of resource (an unresolved name, a URL, a file)\nand the platform filters.\n\n.. code:: python\n\n   import libmambapy.specs as specs\n\n   uc = specs.UnresolvedChannel.parse(\"https://conda.anaconda.org/conda-forge/linux-64\")\n\n   assert uc.location == \"https://conda.anaconda.org/conda-forge\"\n   assert uc.platform_filters == {\"linux-64\"}\n   assert uc.type == specs.UnresolvedChannel.Type.URL\n\nDynamic platforms (as in not known by Mamba) can only be detected with the ``[]`` syntax.\n\n.. code:: python\n\n   import libmambapy.specs as specs\n\n   uc = specs.UnresolvedChannel.parse(\"conda-forge[prius-avx42]\")\n\n   assert uc.location == \"conda-forge\"\n   assert uc.platform_filters == {\"prius-avx42\"}\n   assert uc.type == specs.UnresolvedChannel.Type.Name\n\n\n.. _libmamba_usage_channel:\n\nChannel\n-------\nThe |Channel| are represented by a |CondaURL| and a set of platform filters.\nA display name is also available, but is not considered a stable identification form of the\nchannel, since it depends on the many configuration parameters, such as the channel alias.\n\nWe construct a |Channel| by *resolving* a |UnresolvedChannel|.\nAll parameters that influence this resolution must be provided explicitly.\n\n\n.. code:: python\n\n   import libmambapy.specs as specs\n   import libmambapy.specs.CondaURL as CondaURL\n\n   uc = specs.UnresolvedChannel.parse(\"conda-forge[prius-avx42]\")\n   chan, *_ = specs.Channel.resolve(\n       uc,\n       channel_alias=CondaURL.parse(\"https://repo.mamba.pm\"),\n       # ...\n   )\n\n   assert chan.url.str() == \"https://repo.mamba.pm/conda-forge\"\n   assert chan.platforms == {\"prius-avx42\"}\n   assert chan.display_name == \"conda-forge[prius-avx42]\"\n\nThere are no hard-coded names:\n\n.. code:: python\n\n   import libmambapy.specs as specs\n   import libmambapy.specs.CondaURL as CondaURL\n\n   uc = specs.UnresolvedChannel.parse(\"defaults\")\n   chan, *_ = specs.Channel.resolve(\n       uc,\n       channel_alias=CondaURL.parse(\"https://repo.mamba.pm\"),\n       # ...\n   )\n\n   assert chan.url.str() == \"https://repo.mamba.pm/defaults\"\n\nYou may have noticed that :cpp:func:`Channel.resolve <mamba::specs::Channel::resolve>` returns\nmultiple channels.\nThis is because of custom multichannels, a single name can return multiple channels.\n\n\n.. code:: python\n\n   import libmambapy.specs as specs\n\n   chan_main, *_ = specs.Channel.resolve(\n       specs.UnresolvedChannel.parse(\"pkgs/main\"),\n       # ...\n   )\n   chan_r, *_ = specs.Channel.resolve(\n       specs.UnresolvedChannel.parse(\"pkgs/r\"),\n       # ...\n   )\n\n   defaults = specs.Channel.resolve(\n       specs.UnresolvedChannel.parse(\"defaults\"),\n       custom_multichannels=specs.Channel.MultiChannelMap(\n           {\"defaults\": [chan_main, chan_r]}\n       ),\n       # ...\n   )\n\n   assert defaults == [chan_main, chan_r]\n\n.. note::\n\n   Creating |Channel| objects this way, while highly customizable, can be very verbose.\n   In practice, one can create a ``ChannelContext`` with ``ChannelContext.make_simple`` or\n   ``ChannelContext.make_conda_compatible`` to compute and hold all these parameters from a\n   ``Context`` (itself getting its values from all the configuration sources).\n   ``ChannelContext.make_channel`` can then directly construct a\n   |Channel| from a string.\n\n\nVersion\n-------\nIn the conda ecosystem, a version is an epoch and a pair of arbitrary length sequences of arbitrary\nlength sequences of string and integer pairs.\nLet's unpack this with an example.\nThe version ``1.2.3`` is the outer sequence, it can actually contain as many elements as needed\nso ``1.2.3.4.5.6.7`` is also a valid version.\nFor alpha version, we sometimes see something like ``1.0.0alpha1``.\nThat's the inner sequence of pairs, for the last part ``[(0, \"alpha\"), (1, \"\")]``.\nThere can also be any number, such as in ``1.0.0alpha1dev3``.\nWe can specify another *\"local\"* version, that we can separate with a ``+``, as in ``1.9.0+2.0.0``,\nbut that is not widely used.\nFinally, there is also an epoch, similar to `PEP440 <https://peps.python.org/pep-0440/>`_, to\naccommodate for change in the versioning scheme.\nFor instance, in ``1!2.0.3``, the epoch is ``1``.\n\nTo sum up, a version like ``7!1.2a3.5b4dev+1.3.0``, can be parsed as:\n\n- **epoch**: ``7``,\n- **version**: ``[[(1, \"\")], [(2, \"a\"), (3, \"\")], [(5, \"b\"), (4, \"dev\")]]``\n- **local version**: ``[[(1, \"\")], [(3, \"\")], [(0, \"\")]]``\n\nFinally, all versions are considered equal to the same version with any number of trailing zeros,\nso ``1.2``, ``1.2.0``, and ``1.2.0.0`` are all considered equal.\n\n.. warning::\n\n   The flexibility of conda versions (arguably too flexible) is meant to accommodate differences\n   in various ecosystems.\n   Library authors should stick to well defined version schemes such as\n   `semantic versioning <https://semver.org/>`_,\n   `calendar versioning <https://calver.org/>`_, or\n   `PEP440 <https://peps.python.org/pep-0440/>`_.\n\nA |Version| can be created by parsing a string with\n:cpp:func:`Version.parse <mamba::specs::Version::parse>`.\n\n.. code:: python\n\n   import libmambapy.specs as specs\n\n   v = specs.Version.parse(\"7!1.2a3.5b4dev+1.3.0\")\n\n\nThe most useful operations on versions is to compare them.\nAll comparison operators are available:\n\n.. code:: python\n\n   import libmambapy.specs as specs\n\n   assert specs.Version.parse(\"1.2.0\") == specs.Version.parse(\"1.2.0.0\")\n   assert specs.Version.parse(\"1.2.0\") < specs.Version.parse(\"1.3\")\n   assert specs.Version.parse(\"2!4.0.0\") >= specs.Version.parse(\"1.8\")\n\n\nVersionSpec\n-----------\nA version spec is a way to describe a set of versions.\nWe have the following primitives:\n\n- ``*`` matches all versions (unrestricted).\n- ``==`` for **equal** matches versions equal to the given one (a singleton).\n  For instance ``==1.2.4`` matches ``1.2.4`` only, and not ``1.2.4.1`` or ``1.2``.\n  Note that since ``1.2.4.0`` is the same as ``1.2.4``, this is also matched.\n- ``!=`` for **not equal** is the opposite, it matches all but the given version.\n  For instance ``=!1.2.4`` matches ``1.2.5`` and ``1!1.2.4`` but not ``1.2.4``.\n- ``>`` for **greater** matches versions strictly greater than the current one, for instance\n  ``>1.2.4`` matches ``2.0.0``, ``1!1.0.0``, but not ``1.1.0`` or ``1.2.4``.\n- ``>=`` for **greater or equal**.\n- ``<`` for **less**.\n- ``<=`` for **less or equal**.\n- ``=`` for **starts with** matches versions that start with the same non zero parts of the version.\n  For instance ``=1.7`` matches ``1.7.8``, and ``1.7.0alpha1`` (beware since this is smaller\n  than ``1.7.0``).\n  This spec can equivalently be written ``1.7`` (bare), ``1.7.*``, or ``=1.7.*``.\n- ``=!``  with ``.*`` for **not starts with** matches all versions but the one that starts with\n  the non zero parts specified.\n  For instance ``!=1.7.*`` matches ``1.8.3`` but not ``1.7.2``.\n- ``~=`` for **compatible with** matches versions that are greater or equal and starting with the\n  all but the last parts specified, including zeros.\n  For instance ``~=2.0`` matches ``2.0.0``, ``2.1.3``, but not ``3.0.1`` or ``2.0.0alpha``.\n\nAll version specs can be combined using a boolean grammar where ``|`` means **or** and ``,`` means\n**and**.\nFor instance, ``(>2.1.0,<3.0)|==2.0.1`` means:\n\n- Either\n   - equal to ``2.0.1``,\n   - or, both\n     - greater that ``2.1.0``\n     - and less than ``3.0``.\n\nTo create a |VersionSpec| from a string, we parse it with\n:cpp:func:`VersionSpec.parse <mamba::specs::VersionSpec::parse>`.\nTo check if a given version matches a version spec, we use\n:cpp:func:`VersionSpec.contains <mamba::specs::VersionSpec::contains>`.\n\n.. code:: python\n\n   import libmambapy.specs as specs\n\n   vs = specs.VersionSpec.parse(\"(>2.1.0,<3.0)|==2.0.1\")\n\n   assert vs.contains(specs.Version.parse(\"2.4.0\"))\n   assert vs.contains(specs.Version.parse(\"2.0.1\"))\n   assert not vs.contains(specs.Version.parse(\"3.0.1\"))\n\n.. warning::\n\n   Single versions such as ``3.7`` are parsed by Conda and Mamba as ``==3.7``, which can seem\n   unintuitive.\n   As such, it is recommended to always specify an operator.\n   This mistake is especially likely when writing a match spec such as ``python 3.7``.\n\nBuildNumberSpec\n---------------\nSimilarly, a build number spec is a way to describe a set of build numbers.\nIt's much simpler than the |VersionSpec| in that it does not contain any boolean grammar\n(the ``,`` and ``|`` operators).\n|BuildNumberSpec| only contain primitives similar to those used in |VersionSpec|:\n\n- ``*`` or ``=*`` matches all build numbers (unrestricted).\n- ``=`` for **equal** matches build numbers equal to the given one (a singleton).\n- ``!=`` for **not equal**.\n- ``>`` for **greater** matches versions strictly greater than the current one.\n- ``>=`` for **greater or equal**.\n- ``<`` for **less**.\n- ``<=`` for **less or equal**.\n\nTo create a |BuildNumberSpec| from a string, we parse it\nwith :cpp:func:`BuildNumberSpec.parse <mamba::specs::BuildNumberSpec::parse>`.\nTo check if a given build number matches a build number spec, we use\n:cpp:func:`BuildNumberSpec.contains <mamba::specs::BuildNumberSpec::contains>`.\n\n.. code:: python\n\n   import libmambapy.specs as specs\n\n   bs = specs.BuildNumberSpec.parse(\">2\")\n\n   assert bs.contains(3)\n   assert not bs.contains(2)\n\nOther Specs\n-----------\nThe |GlobSpec| is used to match glob expressions on strings.\nThe only wildcard currently supported is ``*`` which stands for any string (0 or more characters).\nThe glob spec is used as the basis for the |MatchSpec| package name and build string.\n\n.. code:: python\n\n   import libmambapy.specs as specs\n\n   glob = specs.GlobSpec.parse(\"py*\")\n\n   assert glob.contains(\"python\")\n   assert glob.contains(\"pypy\")\n   assert not vs.contains(\"rust-python\")\n\nMatchSpec\n---------\nUltimately, the |MatchSpec| is the way to match on conda packages, that is a way to describe a\nset of packages.\nThis is what is passed in a command line argument such as ``mamba install <match_spec>``.\n\nMatch specs have a complex string representation, which we can informally write as\n``[[<channel>:]<namespace>:]<name>[<version>[=<build_string>]][[<attribute>=<value>, [...]]]``, or\nwith an example\n``conda-forge:ns:python>=3.7=*cypthon[subdir=\"linux-64\",fn=pkg.conda]``.\n\n- ``<channel>``, here ``conda-forge``, describes an |UnresolvedChannel| where the package\n  should come from.\n  It accepts all values from an unresolved channel, such as ``conda-forge/label/micromamba_dev``,\n  URL, local file path, and platforms filters in between brackets.\n- ``<namespace>``, here ``ns`` is a future, not implemented, feature.\n  It is nonetheless parsed, and retrievable.\n- ``<name>``, here ``python`` is the package name or glob expression and is the only mandatory\n  field.\n- Following is the |VersionSpec| ``<version>`` or ``>=3.7`` here.\n- When the version specification is written (but it could also be set to ``=*``), it can be\n  followed by a ``<build_string>`` glob specification, here ``*cpython``.\n- Last, a bracket section of comma separated ``<attribute>`` = ``<value>``.\n  In the example, we have two attributes, ``subdir`` and ``fn``.\n  Attribute values support quoting with ``\"`` or ``'``.\n  As such, they can be useful to set previously mentioned fields without ambiguity.\n  Valid attribute names are:\n\n  - ``channel``, similar to ``<channel>``.\n  - ``name``, similar to ``<name>``.\n  - ``version``, similar to ``<version>`` (can be useful to set version expression containing\n    parentheses and ``,`` and ``|`` operators).\n  - ``build``, similar to ``<build_string>``.\n  - ``build_number`` to set the |BuildNumberSpec|.\n  - ``subdir`` to select the channel subdirectory platform from which the package must come.\n  - ``fn`` to select the filename the package must match.\n  - ``md5`` to specify the MD5 hash the package archive must have.\n  - ``sha256`` to specify the SHA256 hash the package archive must have.\n  - ``license`` to specify the license the package must have.\n  - ``track_features`` to specify a list of ``track_features`` specified at the package build time.\n  - ``optional`` to add the package as a constraint rather than a strict dependency.\n\n.. warning::\n\n   Specifying some value multiple times, such as in ``python>=3.7[version=\"(=3.9|>3.11)\"]``, or\n   ``python[build=\"foo\"][build=\"bar\"]`` is undefined and subject to change in the future.\n\n.. warning::\n\n   When specifying a version in the attribute section, the first ``=`` is parsed as the attribute\n   assignment.\n   That is ``python[version=3.7]`` is equivalent to ``python 3.7``, which is equivalent to\n   ``python==3.7`` (strong equality).\n   This is intuitively different from how we write ``python=3.7``, which we must write with\n   attributes as ``python[version=\"=3.7\"]``.\n\nThe method\n:cpp:func:`MatchSpec.contains_except_channel <mamba::specs::MatchSpec::contains_except_channel>`\ncan be used to check if a package is contained (matched) by the current |MatchSpec|.\nThe somewhat verbose name serves to indicate that the channel is ignored in this function.\nAs mentioned in the :ref:`Channel section<libmamba_usage_channel>`, resolving and matching channels\nis a delicate operation.\nIn addition, the channel is a part that describes the **provenance** of a package and not its content,\nso various applications may want to handle it in different ways.\nThe :cpp:func:`MatchSpec.channel <mamba::specs::MatchSpec::channel>` attribute can be used to\nreason about the possible channels contained in the |MatchSpec|.\n\n.. code:: python\n\n   import libmambapy.specs as specs\n\n   ms = specs.MatchSpec.parse(\"conda-forge::py*[build_number='>4']\")\n\n   assert ms.contains(name=\"python\", build_number=5)\n   assert not ms.contains(name=\"numpy\", build_number=8)\n   assert ms.channel.location == \"conda-forge\"\n"

    "content": ".. _concepts:\n\nConcepts\n--------\n\nA few concepts are extensively used in ``Mamba`` and in this documentation as well.\nYou should start by getting familiar with those as a starting point.\n\n\n.. _prefix:\n\nPrefix/Environment\n==================\n\n\nIn Unix-like platforms, installing a piece of software consists of placing files in subdirectories of an \"installation prefix\":\n\n.. image:: prefix.png\n  :height: 300\n  :align: center\n\n- no file is placed outside of the installation *prefix*\n- dependencies must be installed in the same *prefix* (or standard system prefixes with lower precedence)\n\n.. note::\n    Examples on Unix: the root of the filesystem, the ``/usr/`` and ``/usr/local/`` directories.\n\n| A *prefix* is a fully self-contained and portable installation.\n| To disambiguate with :ref:`root prefix<root-prefix>`, *prefix* is often referred to as *target prefix*. Without an explicit *target* or *root* prefix, you can assume it refers to a *target prefix*.\n\nAn *environment* is just another name for a *target prefix*.\n\nMamba's environments are similar to virtual environments as seen in Python's ``virtualenv`` and similar software, but more powerful since Mamba also manages *native* dependencies and generalizes the virtual environment concept to many programming languages.\n\n.. _root-prefix:\n\nRoot prefix\n===========\n\nWhen downloading for the first time the index of packages for resolution of the environment, or the packages themselves, a *cache* is generated to speed up future operations:\n\n- the index has a :ref:`configurable<configuration>` time-to-live (TTL) during which it will be considered as valid\n- the packages are preferentially hard-linked to the *cache* location\n\nThis *cache* is shared by all *environments* or *target prefixes* based on the same *root prefix*. Basically, that *cache* directory is a subdirectory located at ``$root_prefix/pkgs/``.\n\nThe *root prefix* also provide a convenient structure to store *environments* ``$root_prefix/envs/``, even if you are free to create an *environment* elsewhere.\n\n\n.. _base-env:\n\nBase environment\n================\n\nThe *base* environment is the environment located at the *root prefix*.\n\n| This is a legacy *environment* from ``conda`` implementation that is still heavily used.\n| The *base* environment contains the ``conda`` and ``mamba`` installation alongside a Python installation (since ``mamba`` and ``conda`` require Python to run).\n| ``mamba`` and ``conda``, being themselves Python packages, are installed in the *base* environment, making the CLIs available in all *activated* environments *based* on this *base* environment.\n\n.. note::\n  You can't ``create`` the *base* environment because it's already part of the *root prefix* structure. Directly ``install`` in *base* instead.\n\n\nActivation/Deactivation\n=======================\n\n.. _activation:\n\nActivation\n**********\n\nThe *activation* of an :ref:`environment<prefix>` makes all its contents available to your shell. It mainly adds *target prefix* subdirectories to your ``$PATH`` environment variable.\n\n.. note::\n  *activation* implementation is platform dependent.\n\n| When *activating* an environment from another, you can choose to ``stack`` or not upon the currently activated env.\n| Stacking will result in a new intermediate :ref:`prefix<prefix>`: ``system prefix < base < env1 < env2``.\n\n\n.. _deactivation:\n\nDeactivation\n************\n\nThe *deactivation* is the opposite operation of :ref:`activation<activation>`, removing from your shell what makes the environment content accessible.\n\n\n.. _shell_completion:\n\nShell completion\n****************\n\nAfter initialization, shell completion is available in any new shell.\nJust hit ``<TAB><TAB>`` to get completion when typing your command.\n\nFor example the following command will help you to pick a named environment to activate:\n\n.. code-block:: bash\n\n  micromamba activate <TAB><TAB>\n"

    "content": ".. _mamba:\n\nMamba User Guide\n----------------\n\n``mamba`` is a CLI tool to manage ``conda`` s environments.\n\nIf you already know ``conda``, great, you already know ``mamba``!\n\nIf you're new to this world, don't panic you will find everything you need in this documentation. We recommend to get familiar with :ref:`concepts<concepts>` first.\n\n\nQuickstart\n==========\n\nThe ``mamba create`` command creates a new environment.\n\nYou can create an environment with the name ``nameofmyenv`` by calling:\n\n.. code:: shell\n\n    mamba create -n nameofmyenv <list of packages>\n\n\nAfter this process has finished, you can :ref:`activate<activation>` the virtual environment by\ncalling ``mamba activate <nameofmyenv>``.\nFor example, to install JupyterLab from the ``conda-forge`` channel and then run it, you could use\nthe following commands:\n\n.. code:: shell\n\n    mamba create -n myjlabenv jupyterlab -c conda-forge\n    mamba activate myjlabenv  # activate our environment\n    jupyter lab               # this will start up jupyter lab and open a browser\n\nOnce an environment is activated, ``mamba install`` can be used to install further packages\ninto the environment.\n\n.. code:: shell\n\n    mamba activate myjlabenv\n    mamba install bqplot  # now you can use bqplot in myjlabenv\n    mamba install \"matplotlib>=3.5.0\" cartopy  # now you installed matplotlib with version>=3.5.0 and default version of cartopy\n\nInstead of activating an environment, you can also execute a command inside the environment by\ncalling ``mamba run -n <nameofmyenv>``.\nFor instance, the previous activation example is similar to:\n\n.. code:: shell\n\n    mamba run -n myjlabenv jupyter lab\n\n\n``mamba`` vs ``conda`` CLIs\n===========================\n\n``mamba`` and ``conda`` mainly have the same command line arguments with a few differences.\nFor simple cases, you can swap one for the other.\nFor a full ``conda`` compatible experience, ``conda`` itself uses Mamba's solver under the hood,\nso you can get great speedups from previous versions.\n\n.. code::\n\n  $ mamba --help\n\n  shell                       Generate shell init scripts\n  create                      Create new environment\n  install                     Install packages in active environment\n  update                      Update packages in active environment\n  repoquery                   Find and analyze packages in active environment or channels\n  remove, uninstall           Remove packages from active environment\n  list                        List packages in active environment\n  package                     Extract a package or bundle files into an archive\n  clean                       Clean package cache\n  config                      Configuration of micromamba\n  info                        Information about micromamba\n  constructor                 Commands to support using micromamba in constructor\n  env                         See mamba/micromamba env --help\n  activate                    Activate an environment\n  run                         Run an executable in an environment\n  ps                          Show, inspect or kill running processes\n  auth                        Login or logout of a given host\n  search                      Find packages in active environment or channels\n                              This is equivalent to `repoquery search` command\n\nSpecification files\n===================\n\nThe ``create`` syntax also allows you to use specification or environment files\n(also called *spec files*) to easily re-create environments.\n\nThe supported syntaxes are:\n\n.. contents:: :local:\n\nSimple text spec files\n**********************\n\nThe ``txt`` file contains *one spec per line*. For example, this could look like:\n\n.. code::\n\n  xtensor\n  numpy 1.19\n  xsimd >=7.4\n\n\nTo use this file, pass:\n\n.. code:: shell\n\n  mamba create -n from_file -f spec_file.txt -c conda-forge\n\n.. note::\n\n  You can pass multiple text spec files by repeating the ``-f,--file`` argument.\n\n\nConda YAML spec files\n*********************\n\nMore powerful are ``YAML`` files like the following, because they already contain a desired environment name and the channels to use:\n\n.. code:: yaml\n\n  name: testenv\n  channels:\n    - conda-forge\n  dependencies:\n    - python >=3.6,<3.7\n    - ipykernel >=5.1\n\n    - ipywidgets[build_number=!=0]\n\nThey are used the same way as text files:\n\n.. code:: shell\n\n  mamba create -f env.yml\n\n.. note::\n  CLI options will keep :ref:`precedence<precedence-resolution>` over *target prefix* or *channels* specified in spec files.\n\n.. note::\n  You can pass multiple ``YAML`` spec files by repeating the ``-f,--file`` argument.\n\nExplicit spec files\n*******************\n\nUsing ``conda`` you can generate *explicit* environment lock files. For this, create an environment, activate it, and execute:\n\n.. code:: shell\n\n  conda list --explicit --md5\n\nThese environment files look like the following and precisely \"pin\" the desired package + version + build string. Each package also has a checksum for reproducibility:\n\n.. code::\n\n  # This file may be used to create an environment using:\n  # $ conda create --name <env> --file <this file>\n  # platform: linux-64\n  @EXPLICIT\n  https://conda.anaconda.org/conda-forge/linux-64/_libgcc_mutex-0.1-conda_forge.tar.bz2#d7c89558ba9fa0495403155b64376d81\n  https://conda.anaconda.org/conda-forge/linux-64/libstdcxx-ng-9.3.0-h2ae2ef3_17.tar.bz2#342f3c931d0a3a209ab09a522469d20c\n  https://conda.anaconda.org/conda-forge/linux-64/libgomp-9.3.0-h5dbcf3e_17.tar.bz2#8fd587013b9da8b52050268d50c12305\n  https://conda.anaconda.org/conda-forge/linux-64/_openmp_mutex-4.5-1_gnu.tar.bz2#561e277319a41d4f24f5c05a9ef63c04\n  https://conda.anaconda.org/conda-forge/linux-64/libgcc-ng-9.3.0-h5dbcf3e_17.tar.bz2#fc9f5adabc4d55cd4b491332adc413e0\n  https://conda.anaconda.org/conda-forge/linux-64/xtl-0.6.21-h0efe328_0.tar.bz2#9eee90b98fd394db7a049792e67e1659\n  https://conda.anaconda.org/conda-forge/linux-64/xtensor-0.21.8-hc9558a2_0.tar.bz2#1030174db5c183f3afb4181a0a02873d\n\nTo install such a file with ``mamba``, just pass the ``-f`` flag again:\n\n.. code:: shell\n\n  mamba create -n xtensor -f explicit_env.txt\n\n.. note::\n\n   Explicit spec files are single-platform.\n\n``conda-lock`` YAML spec files\n******************************\n\nUsing ``conda-lock``, you can generate lockfiles which, like explicit spec files, pin precisely and include a checksum for each package for reproducibility.\nUnlike explicit spec files, these \"unified\" lock files are multi-platform.\n\nThese files are named ``conda-lock.yml`` by default, and look like:\n\n.. code::\n\n    # This lock file was generated by conda-lock (https://github.com/conda/conda-lock).

    "content": ".. _troubleshooting:\n\nTroubleshooting\n===============\n\nPlease use the official installer\n---------------------------------\n\nPlease make sure that you use the :ref:`official Mambaforge installer <mamba-install>` to install Mamba.\nOther installation methods are not supported.\n\nMamba should be installed to the ``base`` environment\n-----------------------------------------------------\n\nInstalling Mamba to an environment other than ``base`` is not supported. Mamba must be installed in the ``base`` environment alongside Conda, and no other packages may be installed into ``base``.\n\n.. _base_packages:\n\nNo other packages should be installed to ``base``\n-------------------------------------------------\n\nInstalling packages other than Conda and Mamba into the ``base`` environment is not supported. Mamba must live in the same environment as Conda, and Conda does not support having packages other than Conda itself and its dependencies in ``base``.\n\n.. _defaults_channels:\n\nUsing the ``defaults`` channels\n-------------------------------\n\nIt is **not recommended** to use the\n`Anaconda default channels <https://docs.anaconda.com/free/anaconda/reference/default-repositories/>`_:\n\n- ``pkgs/main``\n- ``pkgs/r`` / ``R``\n- ``msys2``\n- ``defaults`` (which includes all of the above)\n\nPlease note that we won't be able to help resolving any problems you might face with the Anaconda channels.\n\nTo check if you have any Anaconda default channels in your configuration, use::\n\n    $ mamba info\n    ...\n    channel URLs : https://repo.anaconda.com/pkgs/... # BAD!\n                   ...\n                   https://conda.anaconda.org/conda-forge/...\n    ...\n\nPlease change your configuration to use only ``conda-forge`` using one of the following methods.\n\nDisable the default channels in your install commands::\n\n  mamba install --override-channels ...\n\nOr your :file:`environment.yml` file:\n\n.. code-block:: yaml\n\n  name: ...\n  channels:\n    - ...\n    - nodefaults\n\nOr in your :file:`~/.condarc` file:\n\n.. code-block:: yaml\n\n  ...\n  channels:\n    - ...\n    - defaults  # BAD! Remove this if it exists.\n    - nodefaults\n\nMixing the ``defaults`` and ``conda-forge`` channels\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nThe `Anaconda default channels <https://docs.anaconda.com/free/anaconda/reference/default-repositories/>`_\nare **incompatible** with conda-forge.\n\nUsing the default and ``conda-forge`` channels at the same time is not supported and will lead to broken environments:\n\n.. code-block:: yaml\n\n  # NOT supported!\n  channels:\n    - conda-forge\n    - defaults\n\nMamba broken after Conda update\n-------------------------------\n\nMamba sometimes stops working if you update to a very recent version of Conda.\nPlease downgrade to the latest working a version and file a bug report in the Mamba bug tracker\nif the problem has not been reported yet.\n\nMamba or Micromamba broken after an update\n------------------------------------------\n\nWhile we make our best effort to keep backward compatibility, it is not impossible that an update\nbreaks the current installation.\nThe following actions can be tried:\n\n- Reinitializing your shell with ``micromamba shell reinit``.\n- Deleting the package cache (``\"package cache\"`` entries in ``micromamba info``)\n\nlibmamba.so.2: undefined symbol ...\n-----------------------------------\n\nSee :ref:`defaults_channels`.\n\nWindows long paths\n------------------\n\nWindows API historically supports paths up to 260 characters. While it's now possible to used longer ones, there are still limitations related to that.\n\n``libmamba`` internally relies on ``\\\\?\\`` prefixing to handle such paths. If you get error messages advertising such prefix, please have look at the following steps:\n\n\nLong paths support has to be activated\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nsource: Robocop `troubleshooting documentation <https://sema4.ai/docs/automation/troubleshooting/windows-long-path>`_\n\n1. Open the Local Group Policy Editor application: - Start --> type gpedit.msc --> Enter:\n2. Navigate to Computer Configuration > Administrative Templates > System > Filesystem. On the right, find the \"Enable win32 long paths\" item and double-click it\n3. Change the setting to Enabled\n4. Exit the Local Group Policy Editor and restart your computer (or sign out and back in) to allow the changes to finish\n\nIf the problem persists after those steps, try the following:\n\n1. Open the Registry Editor application: - Start --> type regedit.msc and press Enter:\n2. Navigate to HKEY-LOCAL-MACHINE > SYSTEM > CurrentControlSet > Control > FileSystem. On the right, find the LongPathsEnabled item and double-click it\n3. Change the Value data: to 1\n4. Exit the Registry Editor\n\n\ncmd.exe does not support calls to long prefixes\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nWhile ``cmd.exe`` shell support long paths prefixing for directory operations such as ``dir``, it doesn't allow to call an executable or a batch file located at a long path prefix.\n\nThus, the following cases will fail:\n\n- completely\n\n  - calling executables located at long prefixes\n  - installation of packages with pre/post linking or activation ``.bat`` scripts\n\n- partially\n\n  - pre-compilation of ``noarch`` packages, with no impact on capability to use the package but removing it will let artifacts (pycache) on the filesystem\n\n\nHangs during install in QEMU\n----------------------------\nWhen using Mamba/Micromamba inside a QEMU guest, installing packages may sometimes hang forever due to an `issue with QEMU and glibc <https://gitlab.com/qemu-project/qemu/-/issues/285>`_. As a workaround, set ``G_SLICE=always-malloc`` in the QEMU guest, eg.::\n\n  export G_SLICE=always-malloc\n  mamba install ...\n\nSee `#1611 <https://github.com/mamba-org/mamba/issues/1611>`_ for discussion.\n\n\nHangs during package installation on NFS (Network File Systems)\n---------------------------------------------------------------\nWhen using Mamba/Micromamba in a environment with NFS, package installation (e.g., NumPy) may hang at the step when ``libmamba`` attempts to lock a directory.\nA solution is to update the Mamba/Micromamba configuration to not use lockfile by the command::\n\n  micromamba config set use_lockfiles False\n\nSee `#2592 <https://github.com/mamba-org/mamba/issues/2592>`_, `#1446 <https://github.com/mamba-org/mamba/issues/1446>`_, `#1448 <https://github.com/mamba-org/mamba/pull/1448>`_, `#1515 <https://github.com/mamba-org/mamba/issues/1515>`_ for more details.\n\n\n\"libmamba Download error (7) Could not connect to server\"\n---------------------------------------------------------\n``mamba install`` and other ``mamba`` commands yield said errors. This might be due to being flagged by an antivirus.\nA solution is to whitelist the appropriate folders and files; see `#3979 <https://github.com/mamba-org/mamba/issues/3979>`_ for more details.\n"

solutions by inspecting dependency versions as well (libsolv PR:\n  <https://github.com/openSUSE/libsolv/pull/457>) @wolfv\n- properly implement strict channel priority (libsolv PR:\n  <https://github.com/openSUSE/libsolv/pull/459>) @adriendelsalle\n  - Note that this changes the meaning of strict and flexible priority as the\n    previous implementation did not follow conda's semantics. Mamba now has\n    three modes, just like conda: strict, flexible and disabled. Strict will\n    completely disregard any packages from lower-priority channels if a\n    package of the same name exists in a higher priority channel. Flexible\n    will use packages from lower-priority channels if necessary to fulfill\n    dependencies or explicitly requested (e.g. by version number). Disabled\n    will use the highest version number, irregardless of the channel order.\n- allow subdir selection as part of the channel: users can now specify an\n  explicit list of subdirs, for example:\n\n      `-c mychannel[linux-static64, linux-64, noarch]`\n\n  to pull in repodata and packages from these three subdirs.\n  Thanks for the contribution, @afranchuk! #1033\n\nNew

To not break the implementation of libmamba but still enable different\n    logging libraries to be used, the log-handler implementations that can be used\n    with libmamba must provide some advanced features so that the behavior of\n    libmamba is kept as expected. Therefore instead of a classing callback to register\n    for handling emitted log records, the log handler must be an object with a required API\n    that will be used on log record emission but also in various other situations.\n\n    To help potential ad-hoc log-handler implementations, we also provides basic implementations\n    of log-handlers and log-handler features (like \"backtrace\") in `logging_tool.hpp`.\n\n    Overview (where to start looking):\n\n    - `mamba::logging::LogHandler`:\n        The C++ `concept` specifying the interface that a log-handler implementation\n        must provide to be usable by libmamba.\n\n    - `mamba::logging::AnyLogHandler`:\n        A type-erasing type that can store a on object\n        which type satisfies `LogHandler` or a pointer to such type.\n\n    - `mamba::logging::set_log_handler`:\n        The function registering a log handler for usage as soon as the\n        function is returned.\n\n    - `mamba::logging::log`:\n        The function used by libmamba's implementation to log.\n\n    - `mamba::LoggingParams`:\n        Type representing options for the behavior of the logigng system,\n        both on libmamba's side and in the log-handler implementation.\n\n    - `mamba::logging::LogRecord`:\n        Type representing one log record emitted by libmamba or one\n        of it's dependencies (like curl). It provides all the necessary\n        information for the logging implementation to use.\n\n*/\n\n#ifndef MAMBA_CORE_LOGGING_HPP\n#define MAMBA_CORE_LOGGING_HPP\n\n#include <array>\n#include <cassert>\n#include <concepts>\n#include <functional>\n#include <memory>\n#include <optional>\n#include <source_location>\n#include <sstream>\n#include <string>\n#include <typeindex>\n#include <utility>\n#include <vector>\n\n\n// TODO: rename these macros in a more friendly/conflict-averse manner, with a mamba prefix for\n// example.\n#undef LOG\n#undef LOG_TRACE\n#undef LOG_DEBUG\n#undef LOG_INFO\n#undef LOG_WARNING\n#undef LOG_ERROR\n#undef LOG_CRITICAL\n\n// clang-format off\n#define LOG(severity)   mamba::logging::MessageLogger(severity).stream()\n#define LOG_TRACE       LOG(mamba::log_level::trace)\n#define LOG_DEBUG       LOG(mamba::log_level::debug)\n#define LOG_INFO        LOG(mamba::log_level::info)\n#define LOG_WARNING     LOG(mamba::log_level::warn)\n#define LOG_ERROR       LOG(mamba::log_level::err)\n#define LOG_CRITICAL    LOG(mamba::log_level::critical)\n// clang-format on\n\nnamespace mamba\n{\n    /** Level of logging, used to filter out logs which are at a lower level than the current one.\n        @see `mamba::LoggingParams`\n        @see `mamba::logging::LogRecord`\n        @see `mamba::logging::set_log_level`\n     */\n    enum class log_level\n    {\n        trace,\n        debug,\n        info,\n        warn,\n        err,\n        critical,\n\n        // Special values:\n        off,\n        all\n    };\n\n    constexpr auto operator<=>(log_level left, log_level right) noexcept\n    {\n        return static_cast<int>(left) <=> static_cast<int>(right);\n    }\n\n    constexpr auto operator<=>(log_level left, unsigned long right) noexcept\n    {\n        return static_cast<unsigned long>(left) <=> right;\n    }\n\n    /** @returns The name of the specified log level as an UTF-8 null-terminated string. */\n    constexpr auto name_of(log_level level) noexcept -> const char*\n    {\n        constexpr std::array names{ \"trace\", \"debug\",    \"info\", \"warning\",\n                                    \"error\", \"critical\", \"off\",  \"all\" };\n\n        assert(level < sizeof(names));\n        return names.at(static_cast<size_t>(level));\n    }\n\n    /** Parameters for the logging system. */\n    struct LoggingParams\n    {\n        /** Minimum level a log record must have to not be filtered out. */\n        log_level logging_level{ log_level::warn };\n\n        /** Number of log records to keep in the backtrace history.\n            The backtrace feature will be enabled only if the value\n            is different from `0`.\n        */\n        std::size_t log_backtrace{ 0 };\n\n        /** Formatting pattern to use in formatted logs. */\n        std::string_view log_pattern{ \"%^%-9!l%-8n%$ %v\" };

Path separators are preserved, only scheme\n     *   separators and special characters are normalized.\n     * - platform: Subdir such as \"linux-64\", \"osx-arm64\", \"noarch\".\n     * - package: Tarball (e.g. \"numpy-1.24.0-py310_0.conda\") or extracted dir\n     *   (e.g. \"numpy-1.24.0-py310_0/\").\n     *\n     * Example: pkgs/https/repo.example.com/channel/linux-64/numpy-1.24.0-py310_0.conda\n     *\n     * Motivation\n     * ----------\n     * This hierarchy (unlike conda's flat pkgs/ layout) isolates packages by\n     * channel and platform. It avoids collisions when the same package name\n     * exists in different channels, supports multiple platforms in one cache,\n     * and makes cache structure predictable and easy to reason about. Using\n     * package_url ensures cache paths reflect the actual package source location.\n     *\n     * Fallback behavior\n     * -----------------\n     * When PackageInfo::package_url is empty, the function falls back to using\n     * PackageInfo::channel and PackageInfo::platform. The channel is normalized\n     * using the same rules as package_url. If the channel contains a platform\n     * suffix (e.g., \"https://repo.com/channel/noarch\"), it is stripped before\n     * normalization to avoid duplication.\n     */\n    // clang-format on\n    auto package_cache_folder_relative_path(const specs::PackageInfo& s) -> fs::u8path;\n\n    enum class Writable\n    {\n        UNKNOWN,\n        WRITABLE,\n        NOT_WRITABLE,\n        DIR_DOES_NOT_EXIST\n    };\n\n    // TODO layered package caches\n    class PackageCacheData\n    {\n    public:\n\n        explicit PackageCacheData(const fs::u8path& path);\n\n        bool create_directory();\n        void set_writable(Writable writable);\n        Writable is_writable();\n        fs::u8path path() const;\n        void clear_query_cache(const specs::PackageInfo& s);\n\n        bool has_valid_tarball(const specs::PackageInfo& s, const ValidationParams& params);\n        bool has_valid_extracted_dir(const specs::PackageInfo& s, const ValidationParams& params);\n\n    private:\n\n        void check_writable();\n\n        std::map<std::string, bool> m_valid_tarballs;\n        std::map<std::string, bool> m_valid_extracted_dir;\n        Writable m_writable = Writable::UNKNOWN;\n        fs::u8path m_path;\n    };\n\n    class MultiPackageCache\n    {\n    public:\n\n        MultiPackageCache(const std::vector<fs::u8path>& pkgs_dirs, const ValidationParams& params);\n\n        std::vector<fs::u8path> paths() const;\n\n        fs::u8path get_tarball_path(const specs::PackageInfo& s, bool return_empty = true);\n        fs::u8path get_extracted_dir_path(const specs::PackageInfo& s, bool return_empty = true);\n\n        fs::u8path first_writable_path();\n        PackageCacheData& first_writable_cache(bool create = false);\n        std::vector<PackageCacheData*> writable_caches();\n\n        void clear_query_cache(const specs::PackageInfo& s);\n\n    private:\n\n        std::vector<PackageCacheData> m_caches;\n        std::map<std::string, fs::u8path> m_cached_tarballs;\n        std::map<std::string, fs::u8path> m_cached_extracted_dirs;\n        const ValidationParams& m_params;\n    };\n}  // namespace mamba\n\n#endif\n"

It uses string for version (like ShardPackageRecord)\n     *   but NoArchType enum (like RepoDataPackage), and includes runtime-specific\n     *   fields like channel, package_url, platform, filename, signatures, etc.\n     * - ShardPackageRecord is purely for parsing msgpack shards and contains only\n     *   the minimal fields needed for dependency traversal.\n     * - PackageInfo is created from RepoDataPackage when packages are added to the\n     *   solver database, not directly from ShardPackageRecord.\n     *\n     * **Key design decisions:**\n     *\n     * 1. **Simpler msgpack parsing**: The msgpack format from Python shards uses simple\n     *    types that map directly to primitives, avoiding complex type parsing during\n     *    deserialization.\n     *\n     * 2. **Minimal storage**: Only fields needed for dependency traversal (name, version,\n     *    build, dependencies, constraints). Fields like license, timestamp, track_features\n     *    are not needed during traversal.\n     *\n     * 3. **Lazy conversion**: Conversion to specs::RepoDataPackage happens only when\n     *    building repodata for the solver (via to_repo_data_package()), deferring\n     *    Version/NoArchType parsing costs until actually needed.\n     *\n     * 4. **Flexible msgpack handling**: Custom parsing handles various msgpack types\n     *    for sha256/md5 (strings, bytes, EXT types), easier with a dedicated structure.\n     *\n     * This structure supports all fields defined in the shard format specification.\n     * See https://conda.org/learn/ceps/cep-0016 for the complete shard format specification.\n     *\n     * @see specs::RepoDataPackage The canonical package record type used for repodata.json\n     * @see specs::PackageInfo The runtime package representation used throughout the codebase\n     * @see to_repo_data_package() Conversion function to RepoDataPackage\n     * @see from_repo_data_package() Conversion function from RepoDataPackage\n     * @see https://conda.org/learn/ceps/cep-0016 CEP 16 - Sharded Repodata specification\n     */\n    struct ShardPackageRecord\n    {\n        std::string name;\n        std::string version;\n        std::string build;\n        std::size_t build_number = 0;\n        std::size_t size = 0;\n        std::vector<std::string> depends;\n        std::vector<std::string> constrains;\n        std::vector<std::string> track_features;\n\n        std::optional<std::string> sha256;\n        std::optional<std::string> md5;\n        /** Optional path to the site-packages directory for Python packages. */\n        std::optional<std::string> python_site_packages_path;\n        /** Deprecated md5 hash for legacy .tar.bz2 archives. */\n        std::optional<std::string> legacy_bz2_md5;\n        /** Deprecated size for legacy .tar.bz2 archives. */\n        std::optional<std::size_t> legacy_bz2_size;\n        /** Optional architecture string. */\n        std::optional<std::string> arch;\n        /** Optional platform string. */\n        std::optional<std::string> platform;\n        /** Deprecated features string. */\n        std::optional<std::string> features;\n        std::optional<std::string> noarch;\n        std::optional<std::string> license;\n        std::optional<std::string> license_family;\n        std::optional<std::string> subdir;\n        std::optional<std::size_t> timestamp;\n    };\n\n    /**\n     * A shard dictionary containing packages for a single package name.\n     *\n     * Maps to the Python ShardDict type.

This codebase relies on `std::string` and `const char*` to denote UTF-8 encoded text.\n//    However `std::filesystem::path` constructors cannot assume that `std::string` is in\n//    another encoding than the default one for the platform. This leads runtime issues on some\n//    platforms (mostly Windows) where Unicode paths either lead to exceptions being thrown\n//    by standard filesystem functions or invalid Unicode characters replacing the paths' content.\n//    To work around these issues we need to make sure `std::string` and other characters are\n//    assumed to be UTF-8 and paths are built with that knowledge. (The internal storage is optimal\n//    for the platform so it is not a concern.) In the same way we need paths to be convertible\n//    to UTF-8 when converting them to string.\n//    To achieve this we wrap a `std::filesystem::path` into our type `fs::u8path` so that\n//    conversions always happen correctly in its conversion functions, like an encoding barrier.\n//\n// 2. Once using `fs::u8path`, we cannot use the standard library filesystem algorithms even with\n//    `fs::u8path` implicit conversions without risking ending up with `std::filesystem::path` in\n//    code like this:\n//\n//        fs::u8path prefix = ...;\n//        prefix = rstrip(fs::weakly_canonical(util::expand_user(prefix)).string(), sep);\n//\n//    Here if `fs::weakly_canonical` is just an alias for `std::filesystem::weakly_canonical` it\n//    then returns a `std::filesystem::path` and we then call `.string()` on it. That conversion\n//    assumes that the resulting string should be of the system's encoding (it's unspecified by the\n//    standard) which leads on Windows for example to the resulting `prefix` with invalid characters\n//    which are then rejected by directory creation functions used later.\n//    Another example:\n//\n//    for(const auto& entry : std::filesystem::directory_iterator(some_path))\n//         if (ends_with(entry.path().string(), \".json\")) { ...\n//\n//    Here `entry` is a `std::filesystem::directory_entry` therefore `.path()` returns a\n//    `std::filesystem::path` which makes `.string()` return a string with unknown encoding.\n//    Once passed in `ends_with` which takes a `u8path`, we end up with `???.json` because we\n//    assumed in `u8path` constructor that this string would be UTF-8 when it is of unknown\n//    encoding.\n//\n//    This kind of code seems valid but is silently broken. It is very easy to end up in this kind\n//    of situation which makes us consider this situation brittle. Therefore, the only way to\n//    prevent this kind of issue is to make sure every path value passed to and returned by\n//    filesystem functions is first converted to `fs::u8path`, thus giving us guarantees about\n//    encoding of our paths whatever the platform (as long as strings filtered to be UTF-8).\n//\n// 3. Previous versions of this header were using another library `ghc::filesystem` which is an\n//    implementation of the standard filesystem library but with a guarantee that\n//    `std::filesystem::path::string()` will always return UTF-8 encoding and that constructors\n//    taking strings will assume that they are UTF-8. Why did we prefer doing our own wrapping? The\n//    main reason we decided to wrap instead is that we want users of the library to be able to use\n//    the standard filesystem library in conjunction with this library. As `ghc::filesystem` is a\n//    re-implementation of `std::filesystem`, both cannot really be used together (or at least not\n//    without a lot of explicit conversions). With our present wrapping we are completely compatible\n//    with the standard library as we only add a thin encoding conversion layer over its interface\n//    (at least until the standard library provides better options).\n\n\nnamespace mamba::fs\n{\n    // sentinel argument for indicating the current time to last_write_time\n    class now\n    {\n    };\n\n    struct Utf8Options\n    {\n

dependency versions as well (libsolv PR:\n  <https://github.com/openSUSE/libsolv/pull/457>) @wolfv\n- properly implement strict channel priority (libsolv PR:\n  <https://github.com/openSUSE/libsolv/pull/459>) @adriendelsalle\n  - Note that this changes the meaning of strict and flexible priority as the\n    previous implementation did not follow conda's semantics. Mamba now has\n    three modes, just like conda: strict, flexible and disabled. Strict will\n    completely disregard any packages from lower-priority channels if a\n    package of the same name exists in a higher priority channel. Flexible\n    will use packages from lower-priority channels if necessary to fulfill\n    dependencies or explicitly requested (e.g. by version number). Disabled\n    will use the highest version number, irregardless of the channel order.\n- allow subdir selection as part of the channel: users can now specify an\n  explicit list of subdirs, for example:\n\n      `-c mychannel[linux-static64, linux-64, noarch]`\n\n  to pull in repodata and packages from these three subdirs.\n  Thanks for the contribution, @afranchuk! #1033\n\nNew

implement strict channel priority (libsolv PR:\n  <https://github.com/openSUSE/libsolv/pull/459>) @adriendelsalle\n  - Note that this changes the meaning of strict and flexible priority as the\n    previous implementation did not follow conda's semantics. Mamba now has\n    three modes, just like conda: strict, flexible and disabled. Strict will\n    completely disregard any packages from lower-priority channels if a\n    package of the same name exists in a higher priority channel. Flexible\n    will use packages from lower-priority channels if necessary to fulfill\n    dependencies or explicitly requested (e.g. by version number). Disabled\n    will use the highest version number, irregardless of the channel order.\n- allow subdir selection as part of the channel: users can now specify an\n  explicit list of subdirs, for example:\n\n      `-c mychannel[linux-static64, linux-64, noarch]`\n\n  to pull in repodata and packages from these three subdirs.\n  Thanks for the contribution, @afranchuk! #1033\n\nNew
