You should be able to answer the following questions: - How to reproduce the bug? - What is going wrong? - What is the expected behaviour? It is helpful to provide screenshots and screencasts. Then give the following information: - **Version** of `wl-kbptr` used. Use `wl-kbptr --version` to get this. Ideally, check if the issue is present in `main` and use the commit hash as the version and state the enabled features. - **Compositor** used and its version. This is important as compositors have their own implementation of the Wayland compositor even if they can share code or use the same library. - **Distribution** used. Whilst it might not always be relevant, distributions can package the program differently or apply patches. - You **display settings** (optional). Sometimes some bug only happen with some display settings. You can get this information with `wlr-randr` on `wlroots` compositors. If you are not sure about something (e.g. how to get a piece of information, or how to reproduce the bug), don't worry just state what you are able to provide and we'll try to investigate together. ================================================ FILE: .gitignore ================================================ .cache *.gch ================================================ FILE: LICENSE ================================================ GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. TERMS AND CONDITIONS 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: a) The work must carry prominent notices stating that you modified it, and giving a relevant date. b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. 15. Disclaimer of Warranty.

END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library.

But first, please read . ================================================ FILE: README.md ================================================ # wl-kbptr `wl-kbptr` — short for Wayland Keyboard Pointer — is a utility to help move the mouse pointer with the keyboard. See [Supported compositors](#supported-compositors) section for compatibility. ## Modes To enable to select a target and click, it has four different modes: - [`floating`](#floating-mode) — which uses arbitrary areas either given by the user or detected, - [`tile`](#tile-mode) — which uses a grid to select areas, - [`bisect`](#bisect-mode) — which enables to bisect an area, - [`split`](#split-mode) — which enables to successively split an area, - and [`click`](#click-mode) — which triggers a click in the middle of an area. These are set with the `modes` configuration field and can be chained, e.g. `wl-kbptr -o modes=tile,bisect`. Note that if you make a mistake — e.g. select the wrong area — you can always go back on step by pressing the `Backspace` key. This even works between modes. ### Floating mode [Floating Mode Demo](https://github.com/user-attachments/assets/1598128b-e03b-4d06-b47a-bc8a0021f4da) The `floating` mode uses arbitrary selection areas that can be passed by the user through the standard input. Each input line represents an area defined with the `wxh+x+y` format. #### Auto-detection The areas can also be automatically detected with `mode_floating.source` configuration set to `detect`, e.g. `wl-kbptr -o modes=floating,click -o mode_floating.source=detect`. This requires the `wl-kbptr` binary to be built with the `opencv` feature and the compositor to support the [`wlr-screencopy-unstable-v1`](https://wayland.app/protocols/wlr-screencopy-unstable-v1) protocol — see the [supported compositors](#supported-compositors) section and [build instructions](#from-sources) for details. Whilst it doesn't noticeably change the size of the program itself, OpenCV is a 100 MB+ dependency which is not ideal if you want a very small system which is why this is an optional feature. Most distributions will package the program with the option enabled. If not, they will usually provide two packages. You can check if the binary you have has been built with it with `wl-kbptr --version` — it should print `opencv` if supported. ### Tile mode [Tile Mode Demo](https://github.com/user-attachments/assets/d8c9c8dc-2733-4835-9d82-d0f5b093c382) The `tile` mode displays a grid. To select an area, simply type the label associated with the tile you want to select. ### Bisect mode [Bisect Mode Demo](https://github.com/user-attachments/assets/8f8f7fb4-1bb9-4180-9eda-78ee1ff14181) The `bisect` mode enables to bisect a given area. At any point the cursor can be moved at the location marked by the red marker by pressing `Enter` or `Space`. A left, right and middle click can be made by pressing the `g`, `h` and `b` keys respectively on a QWERTY keyboard layout. Note that other layout will use the same keys positions, e.g. `i`, `d`, and `x` with a Dvorak keyboard layout. ### Split mode [Split Mode Demo](https://github.com/user-attachments/assets/760fa154-ce50-47b4-8f9a-26c5ac79a55b) The `split` mode enables to successively split an area with the arrow keys. Just like the `bisect` mode, a left, right and middle click can be made by pressing the `g`, `h` and `b` keys respectively on a QWERTY keyboard layout. ### Click mode The `click` mode simply triggers a click in the middle of the selection area. ## Supported compositors For `wl-kbptr` to work, it requires the following protocols: - [`wlr-layer-shell-unstable-v1`](https://wayland.app/protocols/wlr-layer-shell-unstable-v1) for the program to display on top, - [`wlr-virtual-pointer-unstable-v1`](https://wayland.app/protocols/wlr-virtual-pointer-unstable-v1) to control the mouse pointer, - and [`wlr-screencopy-unstable-v1`](https://wayland.app/protocols/wlr-screencopy-unstable-v1) (optional) to capture the screen for target detection in the `floating` mode. Here are the compositors with which it has been tested: | Compositor | | Notes | | ---------- | --- | ----- | | [Sway](https://swaywm.org) | ✅ | - | | [Hyprland](https://hyprland.org) | ✅ | - | | [niri](https://github.com/YaLTeR/niri) | ✅ | - | | [dwl](https://codeberg.org/dwl/dwl) | ✅ | - | | [labwc](https://labwc.github.io) | ✅ | - | | [Wayfire](https://wayfire.org) | ✅ | The pointer doesn't move to the right location with multiple display outputs.

It can still work with the `--print-only` option and the mouse pointer can then be moved with `ydotool` or similar. | | [Mutter](https://mutter.gnome.org) | ❌ | The compositor doesn't support any of the required protocols. | ## Installation ### Arch Linux If you are using Arch Linux, you can install the [`wl-kbptr` AUR package](https://aur.archlinux.org/packages/wl-kbptr). Recommended way to build and install the package directly from the AUR (gets all required files): ```bash git clone https://aur.archlinux.org/wl-kbptr.git cd wl-kbptr makepkg -si ``` Alternatively, if you only want the `PKGBUILD`: ```bash curl -L 'https://aur.archlinux.org/cgit/aur.git/plain/PKGBUILD?h=wl-kbptr' -o PKGBUILD makepkg -si ``` ### NixOS If you are using NixOS, you can install the [`wl-kbptr` package](https://search.nixos.org/packages?query=wl-kbptr). Nix can also be used to install `wl-kbptr` on other distributions. ### Chimera Linux If you are using Chimera Linux, you can install the [`wl-kbptr` package](https://pkgs.chimera-linux.org/package/current/contrib/x86_64/wl-kbptr) which is available in the [contrib repository](https://chimera-linux.org/docs/apk#repositories). ```bash apk add chimera-repo-contrib apk add wl-kbptr ``` ### Fedora As of now there is no official package through dnf. So you will need to install the dependencies and then run the steps described in the **From sources** section. ```bash sudo dnf install -y \ meson \ wayland-protocols-devel \ gcc \ libwayland-client \ cmake \ wayland-devel \ libxkbcommon-devel \ cairo-devel ``` ### From sources You can build from sources with: ```bash meson setup build --buildtype=release meson compile -C build ``` If you want to build the target detection feature (see [floating mode](#floating-mode)), you need to enable the `opencv` feature: ```bash meson setup build --buildtype=release -Dopencv=enabled meson compile -C build ``` Then install with: ```bash meson install -C build ``` ## Setting the bindings ### Sway ``` mode Mouse { bindsym a mode default, exec 'wl-kbptr-sway-active-win; swaymsg mode Mouse' bindsym Shift+a mode default, exec 'wl-kbptr; swaymsg mode Mouse' # Mouse move bindsym h seat seat0 cursor move -15 0 bindsym j seat seat0 cursor move 0 15 bindsym k seat seat0 cursor move 0 -15 bindsym l seat seat0 cursor move 15 0 # Left button bindsym s seat seat0 cursor press button1 bindsym --release s seat seat0 cursor release button1 # Middle button bindsym d seat seat0 cursor press button2 bindsym --release d seat seat0 cursor release button2 # Right button bindsym f seat seat0 cursor press button3 bindsym --release f seat seat0 cursor release button3 bindsym Escape mode default } bindsym $mod+g exec wl-kbptr-sway-active-win -o modes=floating','click -o mode_floating.source=detect bindsym $mod+Shift+g mode Mouse ``` ### Hyprland ``` # Cursor submap (similar to the Mouse mode in Sway) submap=cursor # Jump cursor to a position bind=,a,exec,hyprctl dispatch submap reset && wl-kbptr && hyprctl dispatch submap cursor # Cursor movement binde=,j,exec,wlrctl pointer move 0 10 binde=,k,exec,wlrctl pointer move 0 -10 binde=,l,exec,wlrctl pointer move 10 0 binde=,h,exec,wlrctl pointer move -10 0 # Left button bind=,s,exec,wlrctl pointer click left # Middle button bind=,d,exec,wlrctl pointer click middle # Right button bind=,f,exec,wlrctl pointer click right # Scroll up and down binde=,e,exec,wlrctl pointer scroll 10 0 binde=,r,exec,wlrctl pointer scroll -10 0 # Scroll left and right binde=,t,exec,wlrctl pointer scroll 0 -10 binde=,g,exec,wlrctl pointer scroll 0 10 # Exit cursor submap # If you do not use cursor timeout or cursor:hide_on_key_press, you can delete its respective calls. bind=,escape,exec,hyprctl keyword cursor:inactive_timeout 3; hyprctl keyword cursor:hide_on_key_press true; hyprctl dispatch submap reset submap = reset # Entrypoint # If you do not use cursor timeout or cursor:hide_on_key_press, you can delete its respective calls. bind=$mainMod,g,exec,hyprctl keyword cursor:inactive_timeout 0; hyprctl keyword cursor:hide_on_key_press false; hyprctl dispatch submap cursor ``` ## Configuration `wl-kbptr` can be configured with a configuration file.

This protocol allows a compositor to suggest for surfaces to render at fractional scales. A client can submit scaled content by utilizing wp_viewport. This is done by creating a wp_viewport object for the surface and setting the destination rectangle to the surface size before the scale factor is applied. The buffer size is calculated by multiplying the surface size by the intended scale. The wl_surface buffer scale should remain set to 1. If a surface has a surface-local size of 100 px by 50 px and wishes to submit buffers with a scale of 1.5, then a buffer of 150px by 75 px should be used and the wp_viewport destination rectangle should be 100 px by 50 px. For toplevel surfaces, the size is rounded halfway away from zero. The rounding algorithm for subsurface position and size is not defined. A global interface for requesting surfaces to use fractional scales. Informs the server that the client will not be using this protocol object anymore. This does not affect any other objects, wp_fractional_scale_v1 objects included. Create an add-on object for the the wl_surface to let the compositor request fractional scales. If the given wl_surface already has a wp_fractional_scale_v1 object associated, the fractional_scale_exists protocol error is raised. An additional interface to a wl_surface object which allows the compositor to inform the client of the preferred scale. Destroy the fractional scale object. When this object is destroyed, preferred_scale events will no longer be sent. Notification of a new preferred scale for this surface that the compositor suggests that the client should use. The sent scale is the numerator of a fraction with a denominator of 120. ================================================ FILE: protocol/meson.build ================================================ wayland_scanner_dep = dependency('wayland-scanner', native: true) wayland_scanner = find_program( wayland_scanner_dep.get_variable('wayland_scanner'), native: true, ) wl_protocol_dir = wayland_protos.get_variable('pkgdatadir') wayland_scanner_code = generator( wayland_scanner, output: '@BASENAME@-protocol.c', arguments: ['private-code', '@INPUT@', '@OUTPUT@'], ) wayland_scanner_header = generator( wayland_scanner, output: '@BASENAME@-client-protocol.h', arguments: ['client-header', '@INPUT@', '@OUTPUT@'], ) client_protocols = [ wl_protocol_dir / 'stable/xdg-shell/xdg-shell.xml', wl_protocol_dir / 'unstable/xdg-output/xdg-output-unstable-v1.xml', wl_protocol_dir / 'stable/viewporter/viewporter.xml', 'wlr-layer-shell-unstable-v1.xml', 'wlr-virtual-pointer-unstable-v1.xml', 'wlr-screencopy-unstable-v1.xml', 'fractional-scale-v1.xml', ] protos_src = [] foreach xml : client_protocols protos_src += wayland_scanner_code.process(xml) protos_src += wayland_scanner_header.process(xml) endforeach ================================================ FILE: protocol/wlr-layer-shell-unstable-v1.xml ================================================ Copyright © 2017 Drew DeVault Permission to use, copy, modify, distribute, and sell this software and its documentation for any purpose is hereby granted without fee, provided that the above copyright notice appear in all copies and that both that copyright notice and this permission notice appear in supporting documentation, and that the name of the copyright holders not be used in advertising or publicity pertaining to distribution of the software without specific, written prior permission.

Clients can use this interface to assign the surface_layer role to wl_surfaces. Such surfaces are assigned to a "layer" of the output and rendered with a defined z-depth respective to each other. They may also be anchored to the edges and corners of a screen and specify input handling semantics. This interface should be suitable for the implementation of many desktop shell components, and a broad number of other applications that interact with the desktop. Create a layer surface for an existing surface. This assigns the role of layer_surface, or raises a protocol error if another role is already assigned. Creating a layer surface from a wl_surface which has a buffer attached or committed is a client error, and any attempts by a client to attach or manipulate a buffer prior to the first layer_surface.configure call must also be treated as errors. After creating a layer_surface object and setting it up, the client must perform an initial commit without any buffer attached. The compositor will reply with a layer_surface.configure event. The client must acknowledge it and is then allowed to attach a buffer to map the surface. You may pass NULL for output to allow the compositor to decide which output to use. Generally this will be the one that the user most recently interacted with. Clients can specify a namespace that defines the purpose of the layer surface. These values indicate which layers a surface can be rendered in. They are ordered by z depth, bottom-most first. Traditional shell surfaces will typically be rendered between the bottom and top layers. Fullscreen shell surfaces are typically rendered at the top layer. Multiple surfaces can share a single layer, and ordering within a single layer is undefined. This request indicates that the client will not use the layer_shell object any more. Objects that have been created through this instance are not affected. An interface that may be implemented by a wl_surface, for surfaces that are designed to be rendered as a layer of a stacked desktop-like environment. Layer surface state (layer, size, anchor, exclusive zone, margin, interactivity) is double-buffered, and will be applied at the time wl_surface.commit of the corresponding wl_surface is called. Attaching a null buffer to a layer surface unmaps it. Unmapping a layer_surface means that the surface cannot be shown by the compositor until it is explicitly mapped again. The layer_surface returns to the state it had right after layer_shell.get_layer_surface. The client can re-map the surface by performing a commit without any buffer attached, waiting for a configure event and handling it as usual. Sets the size of the surface in surface-local coordinates. The compositor will display the surface centered with respect to its anchors. If you pass 0 for either value, the compositor will assign it and inform you of the assignment in the configure event. You must set your anchor to opposite edges in the dimensions you omit; not doing so is a protocol error. Both values are 0 by default. Size is double-buffered, see wl_surface.commit. Requests that the compositor anchor the surface to the specified edges and corners. If two orthogonal edges are specified (e.g. 'top' and 'left'), then the anchor point will be the intersection of the edges (e.g. the top left corner of the output); otherwise the anchor point will be centered on that edge, or in the center if none is specified. Anchor is double-buffered, see wl_surface.commit. Requests that the compositor avoids occluding an area with other surfaces. The compositor's use of this information is implementation-dependent - do not assume that this region will not actually be occluded. A positive value is only meaningful if the surface is anchored to one edge or an edge and both perpendicular edges. If the surface is not anchored, anchored to only two perpendicular edges (a corner), anchored to only two parallel edges or anchored to all edges, a positive value will be treated the same as zero. A positive zone is the distance from the edge in surface-local coordinates to consider exclusive. Surfaces that do not wish to have an exclusive zone may instead specify how they should interact with surfaces that do. If set to zero, the surface indicates that it would like to be moved to avoid occluding surfaces with a positive exclusive zone. If set to -1, the surface indicates that it would not like to be moved to accommodate for other surfaces, and the compositor should extend it all the way to the edges it is anchored to. For example, a panel might set its exclusive zone to 10, so that maximized shell surfaces are not shown on top of it. A notification might set its exclusive zone to 0, so that it is moved to avoid occluding the panel, but shell surfaces are shown underneath it. A wallpaper or lock screen might set their exclusive zone to -1, so that they stretch below or over the panel. The default value is 0. Exclusive zone is double-buffered, see wl_surface.commit. Requests that the surface be placed some distance away from the anchor point on the output, in surface-local coordinates. Setting this value for edges you are not anchored to has no effect. The exclusive zone includes the margin. Margin is double-buffered, see wl_surface.commit. Types of keyboard interaction possible for layer shell surfaces. The rationale for this is twofold: (1) some applications are not interested in keyboard events and not allowing them to be focused can improve the desktop experience; (2) some applications will want to take exclusive keyboard focus. This value indicates that this surface is not interested in keyboard events and the compositor should never assign it the keyboard focus. This is the default value, set for newly created layer shell surfaces. This is useful for e.g. desktop widgets that display information or only have interaction with non-keyboard input devices. Request exclusive keyboard focus if this surface is above the shell surface layer. For the top and overlay layers, the seat will always give exclusive keyboard focus to the top-most layer which has keyboard interactivity set to exclusive. If this layer contains multiple surfaces with keyboard interactivity set to exclusive, the compositor determines the one receiving keyboard events in an implementation- defined manner. In this case, no guarantee is made when this surface will receive keyboard focus (if ever). For the bottom and background layers, the compositor is allowed to use normal focus semantics. This setting is mainly intended for applications that need to ensure they receive all keyboard events, such as a lock screen or a password prompt. This requests the compositor to allow this surface to be focused and unfocused by the user in an implementation-defined manner. The user should be able to unfocus this surface even regardless of the layer it is on. Typically, the compositor will want to use its normal mechanism to manage keyboard focus between layer shell surfaces with this setting and regular toplevels on the desktop layer (e.g. click to focus). Nevertheless, it is possible for a compositor to require a special interaction to focus or unfocus layer shell surfaces (e.g. requiring a click even if focus follows the mouse normally, or providing a keybinding to switch focus between layers). This setting is mainly intended for desktop shell components (e.g. panels) that allow keyboard interaction. Using this option can allow implementing a desktop shell that can be fully usable without the mouse. Set how keyboard events are delivered to this surface. By default, layer shell surfaces do not receive keyboard events; this request can be used to change this. This setting is inherited by child surfaces set by the get_popup request. Layer surfaces receive pointer, touch, and tablet events normally. If you do not want to receive them, set the input region on your surface to an empty region. Keyboard interactivity is double-buffered, see wl_surface.commit. This assigns an xdg_popup's parent to this layer_surface. This popup should have been created via xdg_surface::get_popup with the parent set to NULL, and this request must be invoked before committing the popup's initial state. See the documentation of xdg_popup for more details about what an xdg_popup is and how it is used. When a configure event is received, if a client commits the surface in response to the configure event, then the client must make an ack_configure request sometime before the commit request, passing along the serial of the configure event. If the client receives multiple configure events before it can respond to one, it only has to ack the last configure event. A client is not required to commit immediately after sending an ack_configure request - it may even ack_configure several times before its next surface commit. A client may send multiple ack_configure requests before committing, but only the last request sent before a commit indicates which configure event the client really is responding to. This request destroys the layer surface. The configure event asks the client to resize its surface. Clients should arrange their surface for the new states, and then send an ack_configure request with the serial sent in this configure event at some point before committing the new surface. The client is free to dismiss all but the last configure event it received. The width and height arguments specify the size of the window in surface-local coordinates. The size is a hint, in the sense that the client is free to ignore it if it doesn't resize, pick a smaller size (to satisfy aspect ratio or resize in steps of NxM pixels). If the client picks a smaller size and is anchored to two opposite anchors (e.g. 'top' and 'bottom'), the surface will be centered on this axis. If the width or height arguments are zero, it means the client should decide its own window dimension. The closed event is sent by the compositor when the surface will no longer be shown. The output may have been destroyed or the user may have asked for it to be removed. Further changes to the surface will be ignored. The client should destroy the resource after receiving this event, and create a new surface if they so choose. Change the layer that the surface is rendered on. Layer is double-buffered, see wl_surface.commit. ================================================ FILE: protocol/wlr-screencopy-unstable-v1.xml ================================================ Copyright © 2018 Simon Ser Copyright © 2019 Andri Yngvason Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice (including the next paragraph) shall be included in all copies or substantial portions of the Software.

This protocol allows clients to ask the compositor to copy part of the screen content to a client buffer. Warning! The protocol described in this file is experimental and backward incompatible changes may be made. Backward compatible changes may be added together with the corresponding interface version bump. Backward incompatible changes are done by bumping the version number in the protocol and interface names and resetting the interface version. Once the protocol is to be declared stable, the 'z' prefix and the version number in the protocol and interface names are removed and the interface version number is reset. This object is a manager which offers requests to start capturing from a source. Capture the next frame of an entire output. Capture the next frame of an output's region. The region is given in output logical coordinates, see xdg_output.logical_size. The region will be clipped to the output's extents. All objects created by the manager will still remain valid, until their appropriate destroy request has been called. This object represents a single frame. When created, a series of buffer events will be sent, each representing a supported buffer type. The "buffer_done" event is sent afterwards to indicate that all supported buffer types have been enumerated. The client will then be able to send a "copy" request. If the capture is successful, the compositor will send a "flags" followed by a "ready" event. For objects version 2 or lower, wl_shm buffers are always supported, ie. the "buffer" event is guaranteed to be sent. If the capture failed, the "failed" event is sent. This can happen anytime before the "ready" event. Once either a "ready" or a "failed" event is received, the client should destroy the frame. Provides information about wl_shm buffer parameters that need to be used for this frame. This event is sent once after the frame is created if wl_shm buffers are supported. Copy the frame to the supplied buffer. The buffer must have a the correct size, see zwlr_screencopy_frame_v1.buffer and zwlr_screencopy_frame_v1.linux_dmabuf. The buffer needs to have a supported format. If the frame is successfully copied, a "flags" and a "ready" events are sent. Otherwise, a "failed" event is sent. Provides flags about the frame. This event is sent once before the "ready" event. Called as soon as the frame is copied, indicating it is available for reading. This event includes the time at which presentation happened at. The timestamp is expressed as tv_sec_hi, tv_sec_lo, tv_nsec triples, each component being an unsigned 32-bit value. Whole seconds are in tv_sec which is a 64-bit value combined from tv_sec_hi and tv_sec_lo, and the additional fractional part in tv_nsec as nanoseconds. Hence, for valid timestamps tv_nsec must be in [0, 999999999]. The seconds part may have an arbitrary offset at start. After receiving this event, the client should destroy the object. This event indicates that the attempted frame copy has failed. After receiving this event, the client should destroy the object. Destroys the frame. This request can be sent at any time by the client. Same as copy, except it waits until there is damage to copy. This event is sent right before the ready event when copy_with_damage is requested. It may be generated multiple times for each copy_with_damage request. The arguments describe a box around an area that has changed since the last copy request that was derived from the current screencopy manager instance. The union of all regions received between the call to copy_with_damage and a ready event is the total damage since the prior ready event. Provides information about linux-dmabuf buffer parameters that need to be used for this frame. This event is sent once after the frame is created if linux-dmabuf buffers are supported. This event is sent once after all buffer events have been sent. The client should proceed to create a buffer of one of the supported types, and send a "copy" request. ================================================ FILE: protocol/wlr-virtual-pointer-unstable-v1.xml ================================================ Copyright © 2019 Josef Gajdusek Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice (including the next paragraph) shall be included in all copies or substantial portions of the Software.

This protocol allows clients to emulate a physical pointer device. The requests are mostly mirror opposites of those specified in wl_pointer. The pointer has moved by a relative amount to the previous request. Values are in the global compositor space. The pointer has moved in an absolute coordinate frame. Value of x can range from 0 to x_extent, value of y can range from 0 to y_extent. A button was pressed or released. Scroll and other axis requests. Indicates the set of events that logically belong together. Source information for scroll and other axis. Stop notification for scroll and other axes. Discrete step information for scroll and other axes. This event allows the client to extend data normally sent using the axis event with discrete value. This object allows clients to create individual virtual pointer objects. Creates a new virtual pointer. The optional seat is a suggestion to the compositor. Creates a new virtual pointer. The seat and the output arguments are optional. If the seat argument is set, the compositor should assign the input device to the requested seat. If the output argument is set, the compositor should map the input device to the requested output. ================================================ FILE: share/wl-kbptr.desktop ================================================ [Desktop Entry] Version=1.0 Name=wl-kbptr Comment=Control the mouse pointer with the keyboard Exec=wl-kbptr Terminal=false Type=Application ================================================ FILE: src/config.c ================================================ #include "config.h" #include "log.h" #include "state.h" #include #include #include #include #include /** * `field_color_parse` parses color field values, e.g.: * - 6-digit hex color code (RRGGBB): `#123456`, `123456` * - 8-digit hex color code (RRGGBBAA): `#12345678`, `12345678` * - 3-digit hex color code (RGB): `#123`, `123` * - 4-digit hex color code (RGBA): `#1234`, `1234` */ static int parse_color(void *dest, char *value) { if (value[0] == '#') { value++; } char digits[8]; int len = 0; for (int i = 0; value[i] != '\0'; i++) { if (++len > 8) { return 1; } char c = value[i]; if (c >= '0' && c <= '9') { digits[i] = c - '0'; continue; } c |= 1 << 5; // Makes the character lower case. if (c >= 'a' && c <= 'f') { digits[i] = c - 'a' + 10; continue; } return 2; } switch (len) { case 8:; *((uint32_t *)dest) = digits[7] | digits[6] << 4 | digits[5] << (4 * 2) | digits[4] << (4 * 3) | digits[3] << (4 * 4) | digits[2] << (4 * 5) | digits[1] << (4 * 6) | digits[0] << (4 * 7); break; case 6: *((uint32_t *)dest) = 0xff | digits[5] << (4 * 2) | digits[4] << (4 * 3) | digits[3] << (4 * 4) | digits[2] << (4 * 5) | digits[1] << (4 * 6) | digits[0] << (4 * 7); break; case 4: *((uint32_t *)dest) = digits[3] | digits[3] << 4 | digits[2] << (4 * 2) | digits[2] << (4 * 3) | digits[1] << (4 * 4) | digits[1] << (4 * 5) | digits[0] << (4 * 6) | digits[0] << (4 * 7); break; case 3: *((uint32_t *)dest) = 0xff | digits[2] << (4 * 2) | digits[2] << (4 * 3) | digits[1] << (4 * 4) | digits[1] << (4 * 5) | digits[0] << (4 * 6) | digits[0] << (4 * 7); break; default: return 4; } return 0; } static int parse_double(void *dest, char *value) { *((double *)dest) = atof(value); // TODO: handle errors better. return 0; } static int parse_uint8(void *dest, char *value) { int decoded = atoi(value); if (decoded < 0 || decoded >= 256) { LOG_ERR("Value should be between 0 and 255 (included)."); return 1; } *((uint8_t *)dest) = (uint8_t)decoded; return 0; } static int parse_relative_font_size(void *dest, char *value) { struct relative_font_size *rfs = dest; static const char delims[] = " \t"; int s_len = strlen(value); char buf[s_len + 1]; strcpy(buf, value); buf[s_len] = '\0'; char *strtok_p; char *token = strtok_r(buf, delims, &strtok_p); if (token == NULL) { LOG_ERR("No minimum size."); return 1; } errno = 0; rfs->min = strtod(token, NULL); if (errno) { LOG_ERR("Invalid minimum size."); return 1; } token = strtok_r(NULL, delims, &strtok_p); if (token == NULL) { LOG_ERR("No relative size."); return 1; } errno = 0; rfs->proportion = strtod(token, NULL); if (token[strlen(token) - 1] == '%') { rfs->proportion /= 100.; } if (errno) { LOG_ERR("Invalid relative size."); return 1; } token = strtok_r(NULL, delims, &strtok_p); if (token == NULL) { LOG_ERR("No maximum size."); return 1; } errno = 0; rfs->max = strtod(token, NULL); if (errno) { LOG_ERR("Invalid maximum size."); return 1; } if (rfs->min < 0) { LOG_ERR("Minimum size can't be negative."); return 1; } if (rfs->max < 0) { LOG_ERR("Maximum size can't be negative."); return 1; } if (rfs->proportion < 0) { LOG_ERR("Proportion can't be negative."); return 1; } if (rfs->min > rfs->max) { LOG_ERR("Minimum size can't be greater than maximum size."); return 1; } return 0; } static int parse_home_row_keys(void *dest, char *value) { char ***home_row_keys_ptr = dest; if (value[0] == '\0') { *home_row_keys_ptr = NULL; return 0; } #define ASSERT_FOLLOW_UP_BYTE(c) \ if ((*c & 0b11000000) != 0b10000000) { \ LOG_ERR("Encoding error."); \ goto err; \ } char *b = malloc(HOME_ROW_LEN_WITH_BTN * 5); char **keys = malloc(HOME_ROW_LEN_WITH_BTN * sizeof(char *)); char *c = value; for (int i = 0; i < HOME_ROW_LEN_WITH_BTN; i++) { if (*c == 0) { LOG_ERR("Could not parse home row keys.
