By contrast, the GNU General Public\nLicense is intended to guarantee your freedom to share and change free\nsoftware--to make sure the software is free for all its users. This\nGeneral Public License applies to most of the Free Software\nFoundation's software and to any other program whose authors commit to\nusing it. (Some other Free Software Foundation software is covered by\nthe GNU Lesser General Public License instead.) You can apply it to\nyour programs, too.\n\n When we speak of free software, we are referring to freedom, not\nprice. Our General Public Licenses are designed to make sure that you\nhave the freedom to distribute copies of free software (and charge for\nthis service if you wish), that you receive source code or can get it\nif you want it, that you can change the software or use pieces of it\nin new free programs; and that you know you can do these things.\n\n To protect your rights, we need to make restrictions that forbid\nanyone to deny you these rights or to ask you to surrender the rights.\nThese restrictions translate to certain responsibilities for you if you\ndistribute copies of the software, or if you modify it.\n\n For example, if you distribute copies of such a program, whether\ngratis or for a fee, you must give the recipients all the rights that\nyou have. You must make sure that they, too, receive or can get the\nsource code. And you must show them these terms so they know their\nrights.\n\n We protect your rights with two steps: (1) copyright the software, and\n(2) offer you this license which gives you legal permission to copy,\ndistribute and/or modify the software.\n\n Also, for each author's protection and ours, we want to make certain\nthat everyone understands that there is no warranty for this free\nsoftware. If the software is modified by someone else and passed on, we\nwant its recipients to know that what they have is not the original, so\nthat any problems introduced by others will not reflect on the original\nauthors' reputations.\n\n Finally, any free program is threatened constantly by software\npatents. We wish to avoid the danger that redistributors of a free\nprogram will individually obtain patent licenses, in effect making the\nprogram proprietary. To prevent this, we have made it clear that any\npatent must be licensed for everyone's free use or not licensed at all.\n\n The precise terms and conditions for copying, distribution and\nmodification follow.\n\n GNU GENERAL PUBLIC LICENSE\n TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\n\n 0. This License applies to any program or other work which contains\na notice placed by the copyright holder saying it may be distributed\nunder the terms of this General Public License. The \"Program\", below,\nrefers to any such program or work, and a \"work based on the Program\"\nmeans either the Program or any derivative work under copyright law:\nthat is to say, a work containing the Program or a portion of it,\neither verbatim or with modifications and/or translated into another\nlanguage. (Hereinafter, translation is included without limitation in\nthe term \"modification\".) Each licensee is addressed as \"you\".\n\nActivities other than copying, distribution and modification are not\ncovered by this License; they are outside its scope. The act of\nrunning the Program is not restricted, and the output from the Program\nis covered only if its contents constitute a work based on the\nProgram (independent of having been made by running the Program).\nWhether that is true depends on what the Program does.\n\n 1. You may copy and distribute verbatim copies of the Program's\nsource code as you receive it, in any medium, provided that you\nconspicuously and appropriately publish on each copy an appropriate\ncopyright notice and disclaimer of warranty; keep intact all the\nnotices that refer to this License and to the absence of any warranty;\nand give any other recipients of the Program a copy of this License\nalong with the Program.\n\nYou may charge a fee for the physical act of transferring a copy, and\nyou may at your option offer warranty protection in exchange for a fee.\n\n 2. You may modify your copy or copies of the Program or any portion\nof it, thus forming a work based on the Program, and copy and\ndistribute such modifications or work under the terms of Section 1\nabove, provided that you also meet all of these conditions:\n\n a) You must cause the modified files to carry prominent notices\n stating that you changed the files and the date of any change.\n\n b) You must cause any work that you distribute or publish, that in\n whole or in part contains or is derived from the Program or any\n part thereof, to be licensed as a whole at no charge to all third\n parties under the terms of this License.\n\n c) If the modified program normally reads commands interactively\n when run, you must cause it, when started running for such\n interactive use in the most ordinary way, to print or display an\n announcement including an appropriate copyright notice and a\n notice that there is no warranty (or else, saying that you provide\n a warranty) and that users may redistribute the program under\n these conditions, and telling the user how to view a copy of this\n License. (Exception: if the Program itself is interactive but\n does not normally print such an announcement, your work based on\n the Program is not required to print an announcement.)\n\nThese requirements apply to the modified work as a whole. If\nidentifiable sections of that work are not derived from the Program,\nand can be reasonably considered independent and separate works in\nthemselves, then this License, and its terms, do not apply to those\nsections when you distribute them as separate works. But when you\ndistribute the same sections as part of a whole which is a work based\non the Program, the distribution of the whole must be on the terms of\nthis License, whose permissions for other licensees extend to the\nentire whole, and thus to each and every part regardless of who wrote it.\n\nThus, it is not the intent of this section to claim rights or contest\nyour rights to work written entirely by you; rather, the intent is to\nexercise the right to control the distribution of derivative or\ncollective works based on the Program.\n\nIn addition, mere aggregation of another work not based on the Program\nwith the Program (or with a work based on the Program) on a volume of\na storage or distribution medium does not bring the other work under\nthe scope of this License.\n\n 3. You may copy and distribute the Program (or a work based on it,\nunder Section 2) in object code or executable form under the terms of\nSections 1 and 2 above provided that you also do one of the following:\n\n a) Accompany it with the complete corresponding machine-readable\n source code, which must be distributed under the terms of Sections\n 1 and 2 above on a medium customarily used for software interchange; or,\n\n b) Accompany it with a written offer, valid for at least three\n years, to give any third party, for a charge no more than your\n cost of physically performing source distribution, a complete\n machine-readable copy of the corresponding source code, to be\n distributed under the terms of Sections 1 and 2 above on a medium\n customarily used for software interchange; or,\n\n c) Accompany it with the information you received as to the offer\n to distribute corresponding source code. (This alternative is\n allowed only for noncommercial distribution and only if you\n received the program in object code or executable form with such\n an offer, in accord with Subsection b above.)\n\nThe source code for a work means the preferred form of the work for\nmaking modifications to it. For an executable work, complete source\ncode means all the source code for all modules it contains, plus any\nassociated interface definition files, plus the scripts used to\ncontrol compilation and installation of the executable. However, as a\nspecial exception, the source code distributed need not include\nanything that is normally distributed (in either source or binary\nform) with the major components (compiler, kernel, and so on) of the\noperating system on which the executable runs, unless that component\nitself accompanies the executable.\n\nIf distribution of executable or object code is made by offering\naccess to copy from a designated place, then offering equivalent\naccess to copy the source code from the same place counts as\ndistribution of the source code, even though third parties are not\ncompelled to copy the source along with the object code.\n\n 4. You may not copy, modify, sublicense, or distribute the Program\nexcept as expressly provided under this License. Any attempt\notherwise to copy, modify, sublicense or distribute the Program is\nvoid, and will automatically terminate your rights under this License.\nHowever, parties who have received copies, or rights, from you under\nthis License will not have their licenses terminated so long as such\nparties remain in full compliance.\n\n 5. You are not required to accept this License, since you have not\nsigned it. However, nothing else grants you permission to modify or\ndistribute the Program or its derivative works. These actions are\nprohibited by law if you do not accept this License. Therefore, by\nmodifying or distributing the Program (or any work based on the\nProgram), you indicate your acceptance of this License to do so, and\nall its terms and conditions for copying, distributing or modifying\nthe Program or works based on it.\n\n 6. Each time you redistribute the Program (or any work based on the\nProgram), the recipient automatically receives a license from the\noriginal licensor to copy, distribute or modify the Program subject to\nthese terms and conditions. You may not impose any further\nrestrictions on the recipients' exercise of the rights granted herein.\nYou are not responsible for enforcing compliance by third parties to\nthis License.\n\n 7. If, as a consequence of a court judgment or allegation of patent\ninfringement or for any other reason (not limited to patent issues),\nconditions are imposed on you (whether by court order, agreement or\notherwise) that contradict the conditions of this License, they do not\nexcuse you from the conditions of this License. If you cannot\ndistribute so as to satisfy simultaneously your obligations under this\nLicense and any other pertinent obligations, then as a consequence you\nmay not distribute the Program at all. For example, if a patent\nlicense would not permit royalty-free redistribution of the Program by\nall those who receive copies directly or indirectly through you, then\nthe only way you could satisfy both it and this License would be to\nrefrain entirely from distribution of the Program.\n\nIf any portion of this section is held invalid or unenforceable under\nany particular circumstance, the balance of the section is intended to\napply and the section as a whole is intended to apply in other\ncircumstances.\n\nIt is not the purpose of this section to induce you to infringe any\npatents or other property right claims or to contest validity of any\nsuch claims; this section has the sole purpose of protecting the\nintegrity of the free software distribution system, which is\nimplemented by public license practices. Many people have made\ngenerous contributions to the wide range of software distributed\nthrough that system in reliance on consistent application of that\nsystem; it is up to the author/donor to decide if he or she is willing\nto distribute software through any other system and a licensee cannot\nimpose that choice.\n\nThis section is intended to make thoroughly clear what is believed to\nbe a consequence of the rest of this License.\n\n 8. If the distribution and/or use of the Program is restricted in\ncertain countries either by patents or by copyrighted interfaces, the\noriginal copyright holder who places the Program under this License\nmay add an explicit geographical distribution limitation excluding\nthose countries, so that distribution is permitted only in or among\ncountries not thus excluded. In such case, this License incorporates\nthe limitation as if written in the body of this License.\n\n 9. The Free Software Foundation may publish revised and/or new versions\nof the General Public License from time to time. Such new versions will\nbe similar in spirit to the present version, but may differ in detail to\naddress new problems or concerns.\n\nEach version is given a distinguishing version number. If the Program\nspecifies a version number of this License which applies to it and \"any\nlater version\", you have the option of following the terms and conditions\neither of that version or of any later version published by the Free\nSoftware Foundation. If the Program does not specify a version number of\nthis License, you may choose any version ever published by the Free Software\nFoundation.\n\n 10. If you wish to incorporate parts of the Program into other free\nprograms whose distribution conditions are different, write to the author\nto ask for permission. For software which is copyrighted by the Free\nSoftware Foundation, write to the Free Software Foundation; we sometimes\nmake exceptions for this. Our decision will be guided by the two goals\nof preserving the free status of all derivatives of our free software and\nof promoting the sharing and reuse of software generally.\n\n NO WARRANTY\n\n 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\nFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\nOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\nPROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\nOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\nMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\nTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\nPROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\nREPAIR OR CORRECTION.\n\n 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\nWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\nREDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\nINCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\nOUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\nTO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\nYOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\nPROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\nPOSSIBILITY OF SUCH DAMAGES.\n\n END OF TERMS AND CONDITIONS\n\n How to Apply These Terms to Your New Programs\n\n If you develop a new program, and you want it to be of the greatest\npossible use to the public, the best way to achieve this is to make it\nfree software which everyone can redistribute and change under these terms.\n\n To do so, attach the following notices to the program. It is safest\nto attach them to the start of each source file to most effectively\nconvey the exclusion of warranty; and each file should have at least\nthe \"copyright\" line and a pointer to where the full notice is found.\n\n \n Copyright (C) \n\n This program is free software; you can redistribute it and/or modify\n it under the terms of the GNU General Public License as published by\n the Free Software Foundation; either version 2 of the License, or\n (at your option) any later version.\n\n This program is distributed in the hope that it will be useful,\n but WITHOUT ANY WARRANTY; without even the implied warranty of\n MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the\n GNU General Public License for more details.\n\n You should have received a copy of the GNU General Public License along\n with this program; if not, write to the Free Software Foundation, Inc.,\n 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.\n\nAlso add information on how to contact you by electronic and paper mail.\n\nIf the program is interactive, make it output a short notice like this\nwhen it starts in an interactive mode:\n\n Gnomovision version 69, Copyright (C) year name of author\n Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.\n This is free software, and you are welcome to redistribute it\n under certain conditions; type `show c' for details.\n\nThe hypothetical commands `show w' and `show c' should show the appropriate\nparts of the General Public License. Of course, the commands you use may\nbe called something other than `show w' and `show c'; they could even be\nmouse-clicks or menu items--whatever suits your program.\n\nYou should also get your employer (if you work as a programmer) or your\nschool, if any, to sign a \"copyright disclaimer\" for the program, if\nnecessary. Here is a sample; alter the names:\n\n Yoyodyne, Inc., hereby disclaims all copyright interest in the program\n `Gnomovision' (which makes passes at compilers) written by James Hacker.\n\n , 1 April 1989\n Ty Coon, President of Vice\n\nThis General Public License does not permit incorporating your program into\nproprietary programs. If your program is a subroutine library, you may\nconsider it more useful to permit linking proprietary applications with the\nlibrary.

(thanks to Gonzalo, et.al.)\n* Reorder process scanning to be performed before updating the display\n of the meters in the header\n* Always check the user for a process for any changes.\n This affects multiple platforms that previously didn't correctly handle\n the user field for a process to change at runtime (e.g. due to seteuid\n or similar syscalls).\n* Disable mouse option when support is unavailable\n* Support curses libraries without ncurses mouse support\n (thanks to Santhosh Raju)\n* Support offline and hot-swapping of CPUs on all platforms\n* Fix the CPU Meter for machines with more than 256 CPUs\n* Supplemented the \"show updated/deleted executables\" feature (red basename)\n to indicate when linked libraries were updated (yellow basename)\n* Apply the stale binary highlighting for the EXE column in addition to\n the command line field\n* Add new combined Memory and Swap meter\n* Implement bar and graph mode for NetworkIO Meter\n (thanks to Michael F. Schönitzer)\n* Rework TTY column to be more consistent across platforms\n* Make the CWD column generally available on all platforms\n (thanks to Santhosh Raju et. al.)\n* Add Performance Co-Pilot (PCP) platform support\n This is added via a separate pcp-htop(1) binary which provides remote host\n analysis, new Meters for any PCP metric and new Columns for any PCP process\n metric - see the pcp-htop(5) man page for further details.\n (thanks to Sohaib Mohamed)\n* Add Linux columns and key bindings for process autogroup identifier\n and nice value\n* Change available and used memory reporting on Linux to be based on\n MemAvailable (Kernel 3.14+) (thanks to Chris Cheney and Tomas Wido)\n* Add a new SysArchMeter showing kernel and platform information\n (thanks to ahgamut)\n* Linux memory usage explicitly treats tmpfs memory usage as shared memory\n This is to make memory used by tmpfs visible as this cannot be freed\n unlike normal filesystem cache data.\n* Exclude zram devices when calculating DiskIO on Linux\n* Use PATH lookup for systemctl in systemd meter (thanks to Scott Olson)\n* Add native platform support for NetBSD\n This allows htop to run on NetBSD without the need for active Linux\n emulation of the procfs filesystem.\n (thanks to Santhosh Raju and Nia Alarie)\n* Add NetworkIO, DiskIO, CPU frequency, and battery meter support on NetBSD\n (thanks to Nia Alarie)\n* Fix NetBSD display of in-use and cached memory (thanks to Nia Alarie)\n* Rework NetBSD CPU and memory accounting (thanks to Santhosh Raju)\n* Fix NetBSD accounting of user and kernel threads (thanks to Santhosh Raju)\n* Initial work to allow building with default libcurses on NetBSD\n (thanks to Santhosh Raju)\n* FreeBSD updates -

Be aware the appropriate package is sometimes still called libncurses5 (on Debian/Ubuntu). Also `ncurses` usually comes in two flavours:\n>* With Unicode support.\n>* Without Unicode support.\n>\n> This is also something that is reflected in the package name on Debian/Ubuntu (via the additional 'w' - 'w'ide character support).\n\nList of additional build-time dependencies (based on feature flags):\n* `pkg-config`\n* `sensors`\n* `hwloc`\n* `libcap` (v2.21 or later)\n* `libnl-3` and `libnl-genl-3`\n\n`pkg-config` is optional but recommended. The configure script of `htop` might utilize `pkg-config` to obtain the compiler and linker flags required for a library. Some OS distributions provide `pkg-config` functionalities through an alternative implementation such as `pkgconf`. Look for both names in your package manager.\n\nInstall these and other required packages for C development from your package manager.\n\n**Debian/Ubuntu**\n~~~ shell\nsudo apt install libncursesw5-dev autotools-dev autoconf automake build-essential\n~~~\n\n**Fedora/RHEL**\n~~~ shell\nsudo dnf install ncurses-devel automake autoconf gcc\n~~~\n\n**Archlinux/Manjaro**\n~~~ shell\nsudo pacman -S ncurses automake autoconf gcc\n~~~\n\n**macOS**\n~~~ shell\nbrew install ncurses automake autoconf gcc\n~~~\n\n### Compile from source:\nTo compile from source, download from the Git repository (`git clone` or downloads from [GitHub releases](https://github.com/htop-dev/htop/releases/)), then run:\n~~~ shell\n./autogen.sh && ./configure && make\n~~~\n\n### Install\nTo install on the local system run `make install`. By default `make install` installs into `/usr/local`. To change this path use `./configure --prefix=/some/path`.\n\n### Build Options\n\n`htop` has several build-time options to enable/disable additional features.\n\n#### Generic\n\n * `--enable-unicode`:\n enable Unicode support\n - dependency: *libncursesw*\n - default: *yes*\n * `--enable-affinity`:\n enable `sched_setaffinity(2)` and `sched_getaffinity(2)` for affinity support; conflicts with hwloc\n - default: *check*\n * `--enable-hwloc`:\n enable hwloc support for CPU affinity; disables affinity support\n - dependency: *libhwloc*\n - default: *no*\n * `--enable-static`:\n build a static htop binary; hwloc and delay accounting are not supported\n - default: *no*\n * `--enable-debug`:\n Enable asserts and internal sanity checks; implies a performance penalty\n - default: *no*\n\n#### Performance Co-Pilot\n\n * `--enable-pcp`:\n enable Performance Co-Pilot support via a new pcp-htop utility\n - dependency: *libpcp*\n - default: *no*\n\n#### Linux\n\n * `--enable-sensors`:\n enable libsensors(3) support for reading temperature data\n - dependencies: *libsensors-dev*(build-time), at runtime *libsensors* is loaded via `dlopen(3)` if available\n - default: *check*\n * `--enable-capabilities`:\n enable Linux capabilities support\n - dependency: *libcap*\n - default: *check*\n * `--with-proc`:\n location of a Linux-compatible proc filesystem\n - default: */proc*\n * `--enable-openvz`:\n enable OpenVZ support\n - default: *no*\n * `--enable-vserver`:\n enable VServer support\n - default: *no*\n * `--enable-ancient-vserver`:\n enable ancient VServer support (implies `--enable-vserver`)\n - default: *no*\n * `--enable-delayacct`:\n enable Linux delay accounting support\n - dependencies: *libnl-3-dev*(build-time) and *libnl-genl-3-dev*(build-time), at runtime *libnl-3* and *libnl-genl-3* are loaded via `dlopen(3)` if available and requested\n - default: *check*\n\n\n## Runtime dependencies:\n`htop` has a set of fixed minimum runtime dependencies, which is kept as minimal as possible:\n* `ncurses` libraries for terminal handling (wide character support).\n\n### Runtime optional dependencies:\n`htop` has a set of fixed optional dependencies, depending on build/configure option used:\n\n#### Linux\n* `libdl`, if not building a static binary, is always required when support for optional dependencies (i.e. `libsensors`, `libsystemd`) is present.\n* `libcap`, user-space interfaces to POSIX 1003.1e capabilities, is always required when `--enable-capabilities` was used to configure `htop`.\n* `libsensors`, readout of temperatures and CPU speeds, is optional even when `--enable-sensors` was used to configure `htop`.\n* `libsystemd` is optional when `--enable-static` was not used to configure `htop`. If building statically and `libsystemd` is not found by `configure`, support for the systemd meter is disabled entirely.\n* `libnl-3` and `libnl-genl-3`, if `htop` was configured with `--enable-delayacct` and delay accounting process fields are active.\n* I/O counters are available when the kernel is compiled with `CONFIG_TASK_IO_ACCOUNTING=Y`.\n\n`htop` checks for the availability of the actual runtime libraries as `htop` runs.\n\n#### BSD\nOn most BSD systems `kvm` is a requirement to read kernel information.\n\nMore information on required and optional dependencies can be found in [configure.ac](configure.ac).\n\n## Support\n\nIf you have trouble running `htop` please consult your operating system / Linux distribution documentation for getting support and filing bugs.\n\n## Bugs, development feedback\n\nWe have a [development mailing list](https://htop.dev/mailinglist.html). Feel free to subscribe for release announcements or asking questions on the development of `htop`.\n\nYou can also join our IRC channel [#htop on Libera.Chat](https://web.libera.chat/#htop) and talk to the developers there.\n\nIf you have found an issue within the source of `htop`, please check whether this has already been reported in our [GitHub issue tracker](https://github.com/htop-dev/htop/issues).\nIf not, please file a new issue describing the problem you have found, the potential location in the source code you are referring to and a possible fix if available.\n\n## History\n\n`htop` was invented, developed and maintained by [Hisham Muhammad](https://hisham.hm/) from 2004 to 2019.

You **MAY** use AI assistance for contributing to htop, as long as you follow the principles described below.\n\n2. **Accountability**:\n\n You **MUST** take the responsibility for your contribution.\n\n Contributing to htop means vouching for the quality, license compliance, and utility of your submission.\n\n All contributions, whether from a human author or assisted by large language models (LLMs) or other generative AI tools, must meet the project’s standards for inclusion.\n\n The contributor is always the author and is fully accountable for the entirety of these contributions.\n\n3. **Transparency**:\n\n You **MUST** disclose the use of AI tools when the significant part of the contribution is taken from a tool without changes.\n\n You **SHOULD** disclose the other uses of AI tools, where it might be useful.\n\n Routine use of assistive tools for correcting grammar and spelling, or for clarifying language, does not require disclosure.\n\n - Disclosures are made where authorship is normally indicated. For contributions tracked in git, the recommended method is an `Assisted-by:` commit message trailer.\n\n - Examples:\n\n - `Assisted-by: generic LLM chatbot`\n\n - `Assisted-by: ChatGPTv5`\n\n For contributions outside git commits, disclosure may include document preambles, design file metadata or `Assisted-by:` lines on issues.\n\n4. **Contribution Evaluation**:\n\n AI tools may be used to assist human reviewers by providing analysis and suggestions.\n\n You **MUST NOT** use AI as the sole or final arbiter in making a substantive or subjective judgment on a contribution.\n\n This does not prohibit the use of automated tooling for objective technical validation, such as CI/CD pipelines, automated testing, or spam filtering.\n\n The final accountability for accepting a contribution, even if implemented by an automated system, always rests with the human contributor who authorizes the action.\n\nThis policy has been adapted for htop use from the Fedora policy v1.0 published at .\n\nThe key words “MAY”, “MUST”, “MUST NOT”, and “SHOULD” in this document are to be interpreted as described in [RFC 2119](https://datatracker.ietf.org/doc/html/rfc2119).\n" }, { "path": "docs/styleguide.md", "content": "htop coding style guide\n=======================\n\nNaming conventions\n------------------\n\nNames are important to convey what all those things inside the project are for.\nFilenames for source code traditionally used camel-case naming with the first letter written in uppercase.\nThe file extension is always lowercase.\n\nThe only exceptions here are `htop.c` and `pcp-htop.c`, which contain the main entrance points into the code.\n\nFolders for e.g. platform-specific code or complex features spawning multiple files are written in lowercase, e.g. `linux`, `freebsd`, `zfs`.\n\nInside files, the naming somewhat depends on the context.\nFunction names should include a camel-case prefix before the actual name, separated by an underscore.\nWhile this prefix usually coincides with the module name, this is not required, yet strongly advised.\nOne important exception to this rule are the memory management and the string utility functions from `XUtils.h`.\n\nVariable names inside functions should be short and precise.\nUsing `i` for some loop counter is totally fine, using `someCounterValueForThisSimpleLoop` is not.\nOn the other hand, when you need to hold global storage try to keep this local to your module, i.e. declare such variables `static` within the C source file.\nOnly if your variable really needs to be visible for the whole project (which is really rare) it deserves a declaration in the header, marked `extern`.\n\nFile content structure\n----------------------\n\nThe content within each file is usually structured according to the following loose template:\n\n* Copyright declaration\n* Inclusion of used headers\n* Necessary data structures and forward declarations\n* Static module-private function implementations\n* Externally visible function implementations\n* Externally visible constant structures (pseudo-OOP definitions)\n\nFor header files header guards based on `#ifdef` should be used.\nThese header guards are historically placed **before** the Copyright declaration.\nStick to that for consistency please.\n\nExample:\n\n```c\n#ifndef HEADER_FILENAME\n#define HEADER_FILENAME\n/*\nhtop - Filename.h\n(C) 2021 htop dev team\nReleased under the GNU GPLv2+, see the COPYING file\nin the source distribution for its full text.\n*/\n```\n\nImport and use of headers\n-------------------------\n\nWe use the GPLv2+ as a shorthand indication that we release `htop` under the GNU Public license version 2 but are totally fine with users opting to apply the \"any later version\" clause.\n\nEvery file should import headers for all symbols it's using.\nThus when using a symbol from a header, even if that symbol is already imported by something else you use, you should declare an import for that header.\nDoing so allows for easier restructuring of the code when things need to be moved around.\nIf you are unsure if all necessary headers are included you might use IWYU to tell you.\n\nThe list of includes should be the first thing in the file, after the copyright comment and be followed by two blank lines.\nThe include list should be in the following order, with each group separated by one blank line:\n\n1. `include \"config.h\" // IWYU pragma: keep` if the global configuration\n from `automake`&`autoconfigure` or any of the feature guards for C library headers\n (like `__GNU_SOURCE`) are required, optional otherwise. Beware of the IWYU comment.\n2. Accompanying module header file (for C source files only, missing inside headers)\n3. List of used system headers (non-conditional includes)\n4. List of used program headers\n5. Conditionally included header files, system headers first\n\nThe list of headers should be sorted with includes from subdirectories following after files inside their parent directory.\nThus `unistd.h` sorts before `sys/time.h`.\n\nWhen `XUtils.h` is used by the module itself or any of its included headers, the C source file must include `config.h` in the manner noted above.\nFailure to do so will cause a compilation error (sanity check inside `XUtils.h`) or may result in other, hard-to-debug compilation issues.\nThe include for `config.h` is only ever placed in the C source file and never in any header file.\nFor further details see PR #1337 in our issue tracker.\n\nSymbol Exports\n--------------\n\nExports of symbols should be used sparingly.\nThus unless a function you write is intended to become public API of a module you should mark it as `static`.\nIf a function should be public API an appropriate declaration for that function has to be placed in the accompanying header file.\n\nPlease avoid function-like macros, in particular when exporting them in a header file.\nThey have several downsides (re-evaluation of arguments, syntactic escapes, weak typing) for which usually a better alternative like an actual function exists.\nFurthermore when using function-like `define`s you may need to mark certain headers for IWYU so tracking of used symbols works.\n\nMemory Management\n-----------------\n\nWhen allocating memory make sure to free resources properly.\nFor allocation this project uses a set of tiny wrappers around the common functions `malloc`, `calloc` and `realloc` named `xMalloc`, `xCalloc` and `xRealloc`.\nThese functions check that memory allocation worked and error out on failure.\n\nAllocation functions assert the amount of memory requested is non-zero.\nTrying to allocate 0 bytes of memory is an error.\nPlease use the explicit value `NULL` in this case and handle it in your code accordingly.\n\nIf the allocated block of memory is intended to hold an array of values, you should use the alternate functions `xReallocArray` and `xReallocArrayZero` instead.\n\nWorking with Strings\n--------------------\n\nIt is strongly encouraged to use the functions starting with `String_` from `XUtils.h` for working with zero-terminated strings as these make the API easier to use and are intended to make the intent of your code easier to grasp.\n\nThus instead of `!strcmp(foo, \"foo\")` it's preferred to use `String_eq(foo, \"foo\")` instead.\nWhile sometimes a bit more to type, this helps a lot with making the code easier to follow.\n\nStyling the code\n----------------\n\nNow for the style details that can mostly be automated: Indentation, spacing and bracing.\nWhile there is no definitive code style we use, a set of rules loosely enforced has evolved.\n\nIndentation in the code is done by three (3) spaces. No tabs are used. Ever.\n\nBefore and after keywords should be a space, e.g. `if (condition)` and `do { … } while (condition);`.\n\nAfter opening and before closing braces a new line should be started.\nContent of such encoded blocks should be indented one level further than their enclosing block.\n\nIf a line of source code becomes too long, or when structuring it into multiple parts for clarity, the continuation line should be indented one more level than the first line it continues:\n\n```c\nif (very_long_condition &&\n another_very_complex_expression &&\n something_else_to_check) {\n // Code follows as normal ...\n} else {\n\n}\n```\n\nBraces around simple single code statements (return, break, continue, goto, trivial assignments) are usually left out.\n\n```c\nif (answer)\n return 42;\n```\n\nIf it helps readability (with several unrelated if statements in a row) or to avoid dangling-else situations braces can be added.\n\nControl flow statements and the instruction making up their body should not be put on a single line,\ni.e. after the condition of an if statement a new line should be inserted and the body indented accordingly.\n\n```c\nif (answer)\n return 42;\nelse if (again)\n continue;\nelse\n break;\n```\n\nWhen the statements that form control flow constructs are complex (e.g. more than just a simple assignment or jump) or need explanatory comments you should use braces.\nIf any block of such a statement uses braces then all blocks of that statement must have braces too.\n\n```c\nif ((fd = open(filename, O_RDONLY)) >= 0 &&\n (amtRead = read(buffer, sizeof(buffer))) > 0) {\n // Parse the information further ...\n metric = handleBufferContent(buffer, amtRead);\n} else {\n metric = -1;\n}\n\nif (fd >= 0)\n close(fd);\n```\n\nWhile the existing code base isn't fully consistent with this code style yet it is strongly recommended that new code follows these rules.\nAdapting surrounding code near places you need to touch is encouraged.\nTry to split off such changes into a separate, clean-up only commit to reduce noise while reviewing your changes.\n\nWhen writing your code consistency with the surrounding codebase is favoured.\n\nDon't shy away from leaving (single) blank lines to separate different groups of related statements.\nThey can be a great asset to structure the flow of a method.\n\n```c\n int stuff = 0;\n\n // If asked for gives only half the answer ...\n if (param)\n stuff = 21;\n\n // Compute the answer\n stuff %= 2;\n stuff *= 4;\n stuff *= 5;\n stuff += !!stuff;\n stuff *= 2;\n\n return stuff;\n```\n\nIf you want to automate formatting your code, the following command gives you a good baseline of how it should look:\n\n```bash\nastyle -r -xb -s3 -p -xg -c -k1 -W1 -H \\*.c \\*.h\n```\n\nWorking with System APIs\n------------------------\n\nPlease try to be considerate when using modern platform features.\nWhile they usually provide quite a performance gain or make your life easier, it is beneficial if `htop` runs on rather ancient systems.\nThus when you want to use such features you should try to have an alternative available that works as a fallback.\n\nAn example for this are functions like `fstatat` on Linux that extend the kernel API on modern systems.\nBut even though it has been around for over a decade you are asked to provide a POSIX alternative like emulating such calls by `fstat` if this is doable.\nIf an alternative cannot be provided you should gracefully downgrade. That could make a feature that requires this shiny API unavailable on systems that lack support for that API. Make this case visually clear to the user.\n\nIn general, code written for the project should be able to compile on any C99-compliant compiler.\n\nWriting documentation\n---------------------\n\nThe primary user documentation should be the man file which you can find in `htop.1.in`.\n\nAdditional documentation, like this file, should be written in gh-style markdown.\nMake each sentence one line.\nMarkdown will combine these in output formats.\nIt does only insert a paragraph if you insert a blank line into the source file.\nThis way git can better diff and present the changes when documentation is altered.\n\nDocumentation files reside in the `docs/` directory and have a `.md` extension.\n\nWriting pull-requests (PRs)\n---------------------------\n\nWhen writing your PR or patch, the set of patches should contain the minimal changes required.\nEach patch in itself should ideally be self-contained and runable.\nThe commit comment should be descriptive (`Updated Foo.c` is not), explain what the changes are and describe why they were made.\nWhile in trivial cases a short subject suffices, more complex changes might warrant a longer description and explanation of the rationale behind the changes.\n\nA PR should not contain any merge commits.\nTo follow the upstream branch of your PR rebase your work instead.\n\nAvoid small commits that just fix typos that another of your commits introduced.\nInstead squash those changes in the appropriate commit that introduced that mistake.\nGit offers `git commit --fixup=` and `git rebase -i --autosquash` to help you with this.\n\nYour final PR should contain a minimal set of reasonably sized commits that by themselves are easy to review.\nIf you open a PR you need to follow up to resolve any comments/change requests.\nOtherwise it may be closed without merging.\n\nRebase early. Rebase often.\n\nPlease check the [AI-Assisted Contributions Policy](ai-contributions-policy.md) for requirements and mandatory disclosure in your commits and PRs if you use AI assistance in creating your work.\n" }, { "path": "dragonflybsd/DragonFlyBSDMachine.c", "content": "/*\nhtop - DragonFlyBSDMachine.c\n(C) 2014 Hisham H.

Blank lines are ignored.\nLines starting with the \"#\" character are treated as comments.\n.SH \"METERS\"\nThe following is an example configuration for a new Redis meter:\n.LP\n.ft CR\n.nf\n.in +0.5i\n[redisclient]\ncaption = Redis clients\ntype = bar\nblocked.metric = redis.blocked_clients\nblocked.color = blue\nblocked.label = blk\nclients.metric = redis.connected_clients\nclients.color = green\nclients.label = conn\n.in\n.fi\n.ft 1\n.LP\nA configuration file can contain multiple meter definitions.\nEach definition begins with a identifying name enclosed by\nsquare brackets \\-\n.I redisclient\nin this example.\nThe name is used internally within\n.B pcp-htop\nand must be unique, must begin with an alphabetic character,\nand may subsequently only contain alphanumeric characters or\nthe underscore character.\nNo whitespace or other characters are allowed.\n.LP\nThere are several parameters that define the way the meter\nwill be displayed to the user.\n.TP 5\n.B caption\nThis value is displayed on the Setup screen once the meter\nhas been selected.\nA truncated version of the\n.I caption\nwill also be displayed (followed by a colon) on the primary\ndisplay while the meter is updating.\n.TP\n.B description\nThis can be used to provide more detail during the meter\nselection process on the Setup screen, and if present it is\ndisplayed in the \"Available Meters\" column.\nIf not present, the\n.B caption\nwill be used for this.\nIf neither is present, the internal (mandatory)\n.B name\nwill be used.\n.TP\n.B type\nThis setting allows a preferred default meter type to be specified.\nThe associated value must be one of\n.IR bar ,\n.IR text ,\n.IR graph ,\nor\n.IR led .\nIf no value is provided for a dynamic meter, the default value of\n.IR text\nwill be used.\n.TP\n.B maximum\nA numeric value can also be set to size the meter, such that\nvalues (e.g. for a\n.I bar\ntype meter display) will be scaled within range zero to\n.IR maximum .\n.LP\nThe remaining definition syntax describes the individual\nmetric(s) which will be used to animate the meter.\nOne or more metrics must be specified for each meter and\nthere are several properties associated with each.\nOnce again, these metrics must be named (the same rules\ndescribed above for meters apply here) and the following\nproperties can be configured:\n.TP 5\n.B name.metric\nThis is the only mandatory field and associates a PCP metric\nwith the meter.\nValues sampled for each metric at runtime provide the\nanimation visible in the\n.B pcp-htop\ndisplay.\nThe metric specification can be either a PCP metric name as\nlisted by\n.BR pminfo (1)\nor a \"derived\" metric expression.\nThe format for derived metric expressions is described on the\n.BR pmRegisterDerived (3)\nmanual page.\n.TP\n.B name.color\nSetting color to be used when rendering metric values.\nPossible values are\n.IR red ,\n.IR green ,\n.IR blue ,\n.IR cyan ,\n.IR magenta ,\n.IR yellow ,\n.IR gray ,\n.I darkgray\nor\n.IR white .\n.TP\n.B name.label\nAn optional, short label to display before the metric value.\nThe \":\" character will be appended to the\n.I label\nbefore the metric value part of the display.\n.TP\n.B name.suffix\nAn optional, short suffix to display after the metric value.\nCommonly used to indicate values as a percentage using a \"%\"\n.I suffix\nvalue and to provide the base unit of measurement.\nNote that since PCP maintains units for metrics, for those\nmetrics that have dimension in \"space\" (bytes, kilobytes,\nmegabytes, etc), a suffix will be automatically appended.\n.SH \"COLUMNS\"\nThe following is an example configuration for a new column\nshowing open file descriptors for each process:\n.LP\n.ft CR\n.nf\n.in +0.5i\n[openfds]\nheading = FDS\ncaption = FDCOUNT\ndescription = Open file descriptors\nmetric = proc.fd.count\nwidth = 3\n.in\n.fi\n.ft 1\n.LP\nA configuration file can contain multiple column definitions.\nEach definition begins with a identifying name enclosed\nby square brackets \\-\n.I openfds\nin this example, and the same rules apply as described above\nfor meter names.\n.LP\nEach column must specify a metric.\nOptional parameters can also be set.\n.TP 5\n.B metric\nAs with meters, the metric value must be either a PCP metric\nname as listed by\n.BR pminfo (1)\nor a derived metric.\nThe metric must have an instance domain (set of values) and\nthat instance domain must map to the set of processes with\nthe instance identifier being PIDs (process identifiers).\nTypically this will be metrics from the\n.I proc\nor\n.I hotproc\nnamespace (\\c\n.BR pmdaproc (1)),\nbut metrics from other domains (\\c\n.BR pmdabpf (1),\netc) that have per-process values are equally applicable.\n.TP\n.B width\nColumn width to use when displaying values for the metric.\nA negative value can be used to specify left alignment.\nAn upper column limit of 28 characters is enforced.\nThe default column width is 5 characters.\n.TP\n.B heading\nThe short title that will be displayed at the head of the\ncolumn \\- usually a short, cryptic, all uppercase string.\n.TP\n.B caption\nA short identifying word presented to users on the Setup\nscreen under both the Available and Active Columns lists.\n.TP\n.B description\nText that assists users to understand the meaning of this\ncolumn when it is being presented via the Setup screen in\nthe Available Columns list.\n.SH \"SEE ALSO\"\n.BR pcp-htop (1),\n.BR pminfo (1),\n.BR pmcd (1),\n.BR pmdaproc (1),\n.BR pmdabpf (1)\nand\n.BR pmRegisterDerived (3).\n.SH
