1 | # Changelog
2 |
3 | All notable changes to this project will be documented in this file.
4 |
5 | The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
6 | and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
7 |
8 | ## Unreleased
9 |
10 | ### Added
11 |
12 | - New configuration options for modes. These options apply to all keybindings in a mode.
13 | - `swallow` mode option: all keybindings associated with this mode do not emit events
14 | - `oneoff` mode option: automatically exits a mode after using a keybind
15 | - `DESTDIR` variable for the `install` target in the `Makefile` to help
16 | packaging and installation. To install in a subdirectory, just call `make
17 | DESTDIR=subdir install`.
18 | - Detection of added/removed devices (e.g., when plugging or unplugging a
19 | keyboard). The devices are grabbed by `swhkd` if they match the `--device`
20 | parameters if present or if they are recognized as keyboard devices otherwise.
21 | - `Altgr` modifier added (https://github.com/waycrate/swhkd/pull/213).
22 |
23 | ### Changed
24 |
25 | - The project `Makefile` now builds the polkit policy file dynamically depending
26 | on the target installation directories.
27 | - Alt modifier no longer maps to the right aly key. It only maps to the left alt key. Right alt is referred to as Altgr (alt graph).
28 | - Tokio version bumped from 1.23.0 to 1.24.2 (https://github.com/waycrate/swhkd/pull/198).
29 |
30 | ### Fixed
31 |
32 | - Mouse cursors and other devices are no longer blocked when running `swhkd`.
33 | - Option prefixes on modifiers are now properly parsed. e.g., `~control` is now
34 | understood by `swhkd` as the `control` modifier with an option
35 | - Install mandocs in the correct locations.

/CODE_OF_CONDUCT.md:
--------------------------------------------------------------------------------
1 | # Contributor Covenant Code of Conduct
2 |
3 | ## Our Pledge
4 |
5 | We as members, contributors, and leaders pledge to make participation in our
6 | community a harassment-free experience for everyone, regardless of age, body
7 | size, visible or invisible disability, ethnicity, sex characteristics, gender
8 | identity and expression, level of experience, education, socio-economic status,
9 | nationality, personal appearance, race, religion, or sexual identity
10 | and orientation.
11 |
12 | We pledge to act and interact in ways that contribute to an open, welcoming,
13 | diverse, inclusive, and healthy community.
14 |
15 | ## Our Standards
16 |
17 | Examples of behavior that contributes to a positive environment for our
18 | community include:
19 |
20 | * Demonstrating empathy and kindness toward other people
21 | * Being respectful of differing opinions, viewpoints, and experiences
22 | * Giving and gracefully accepting constructive feedback
23 | * Accepting responsibility and apologizing to those affected by our mistakes,
24 | and learning from the experience
25 | * Focusing on what is best not just for us as individuals, but for the
26 | overall community
27 |
28 | Examples of unacceptable behavior include:
29 |
30 | * The use of sexualized language or imagery, and sexual attention or
31 | advances of any kind
32 | * Trolling, insulting or derogatory comments, and personal or political attacks
33 | * Public or private harassment
34 | * Publishing others' private information, such as a physical or email
35 | address, without their explicit permission
36 | * Other conduct which could reasonably be considered inappropriate in a
37 | professional setting
38 |
39 | ## Enforcement Responsibilities
40 |
41 | Community leaders are responsible for clarifying and enforcing our standards of
42 | acceptable behavior and will take appropriate and fair corrective action in
43 | response to any behavior that they deem inappropriate, threatening, offensive,
44 | or harmful.
45 |
46 | Community leaders have the right and responsibility to remove, edit, or reject
47 | comments, commits, code, wiki edits, issues, and other contributions that are
48 | not aligned to this Code of Conduct, and will communicate reasons for moderation
49 | decisions when appropriate.
50 |
51 | ## Scope
52 |
53 | This Code of Conduct applies within all community spaces, and also applies when
54 | an individual is officially representing the community in public spaces.
55 | Examples of representing our community include using an official e-mail address,
56 | posting via an official social media account, or acting as an appointed
57 | representative at an online or offline event.
58 |
59 | ## Enforcement
60 |
61 | Instances of abusive, harassing, or otherwise unacceptable behavior may be
62 | reported to the community leaders responsible for enforcement at
63 | aakashsensharma@gmail.com.
64 | All complaints will be reviewed and investigated promptly and fairly.
65 |
66 | All community leaders are obligated to respect the privacy and security of the
67 | reporter of any incident.
68 |
69 | ## Enforcement Guidelines
70 |
71 | Community leaders will follow these Community Impact Guidelines in determining
72 | the consequences for any action they deem in violation of this Code of Conduct:
73 |
74 | ### 1. Correction
75 |
76 | **Community Impact**: Use of inappropriate language or other behavior deemed
77 | unprofessional or unwelcome in the community.
78 |
79 | **Consequence**: A private, written warning from community leaders, providing
80 | clarity around the nature of the violation and an explanation of why the
81 | behavior was inappropriate. A public apology may be requested.
82 |
83 | ### 2. Warning
84 |
85 | **Community Impact**: A violation through a single incident or series
86 | of actions.
87 |
88 | **Consequence**: A warning with consequences for continued behavior. No
89 | interaction with the people involved, including unsolicited interaction with
90 | those enforcing the Code of Conduct, for a specified period of time. This
91 | includes avoiding interactions in community spaces as well as external channels
92 | like social media. Violating these terms may lead to a temporary or
93 | permanent ban.
94 |
95 | ### 3. Temporary Ban
96 |
97 | **Community Impact**: A serious violation of community standards, including
98 | sustained inappropriate behavior.
99 |
100 | **Consequence**: A temporary ban from any sort of interaction or public
101 | communication with the community for a specified period of time. No public or
102 | private interaction with the people involved, including unsolicited interaction
103 | with those enforcing the Code of Conduct, is allowed during this period.
104 | Violating these terms may lead to a permanent ban.
105 |
106 | ### 4. Permanent Ban
107 |
108 | **Community Impact**: Demonstrating a pattern of violation of community
109 | standards, including sustained inappropriate behavior, harassment of an
110 | individual, or aggression toward or disparagement of classes of individuals.
111 |
112 | **Consequence**: A permanent ban from any sort of public interaction within
113 | the community.

4 |
5 | # Building:
6 |
7 | `swhkd` and `swhks` install to `/usr/local/bin/` by default. You can change this behaviour by editing the [Makefile](../Makefile) variable, `DESTDIR`, which acts as a prefix for all installed files. You can also specify it in the make command line, e.g. to install everything in `subdir`: `make DESTDIR="subdir" install`.
8 |
9 | Note: On some systems swhkd daemon might disable wifi due to issues with rfkill, you could pass `make NO_RFKILL_SW_SUPPORT=1` while buliding to disable rfkill support.

A next-generation hotkey daemon for Wayland/X11 written in Rust.

14 |
15 | ## SWHKD
16 |
17 | **S**imple **W**ayland **H**ot**K**ey **D**aemon
18 |
19 | `swhkd` is a display protocol-independent hotkey daemon made in
20 | [Rust](https://www.rust-lang.org). `swhkd` uses an easy-to-use configuration
21 | system inspired by `sxhkd`, so you can easily add or remove hotkeys.
22 |
23 | It also attempts to be a drop-in replacement for `sxhkd`, meaning your `sxhkd`
24 | config file is also compatible with `swhkd`.
25 |
26 | Because `swhkd` can be used anywhere, the same `swhkd` config can be used across
27 | Xorg or Wayland desktops, and you can even use `swhkd` in a TTY.
28 |
29 | ## Installation and Building
30 |
31 | [Installation and building instructions can be found here.](./INSTALL.md)
32 |
33 | ## Running
34 |
35 | ```bash
36 | ./swhks && doas ./swhkd
37 | ```
38 |
39 | The doas or sudo can be skipped by making the swhkd binary a setuid binary.
40 | This can be done by running the following command:
41 |
42 | ```bash
43 | sudo chown root:root swhkd
44 | sudo chmod u+s swhkd
45 | ```
46 |
47 | then to start,
48 | ```bash
49 | swhks &
50 | swhkd
51 | ```
52 |
53 | ## Runtime signals
54 |
55 | After opening `swhkd`, you can control the program through signals:
56 |
57 | - `sudo pkill -USR1 swhkd` — Pause key checking
58 | - `sudo pkill -USR2 swhkd` — Resume key checking
59 | - `sudo pkill -HUP swhkd` — Reload config file
60 |
61 | ## Configuration
62 |
63 | `swhkd` closely follows `sxhkd` syntax, so most existing `sxhkd` configs should
64 | be functional with `swhkd`.
65 | More information about the sxhkd syntax can be found in the official man pages from the [arch wiki](https://man.archlinux.org/man/sxhkd.1).
66 |
67 | The default configuration file is in `~/.config/swhkd/swhkdrc` with a fallback to `etc/swhkd/swhkdrc`.
68 |
69 | If you use Vim, you can get `swhkd` config syntax highlighting with the
70 | [swhkd-vim](https://github.com/waycrate/swhkd-vim) plugin. Install it in
71 | vim-plug with `Plug 'waycrate/swhkd-vim'`.
72 |
73 | All supported key and modifier names are listed in `man 5 swhkd-keys`.
74 |
75 | ## Environment Variables
76 |
77 | The environment variables are now sourced using the SWHKS binary, running in the background which are then supplemented
78 | to the command that is to be run, thus emulating the environment variables in the default shell.
79 |
80 | The commands are executed via *SHELL -c 'command'*, hence the environment is sourced from the default shell.
81 | If the user wants to use a different set of environment variables, they can set the environment variables
82 | in the default shell or export the environment variables within a logged in instance of their shell before
83 | running the SWHKS binary.
84 |
85 | ## Autostart
86 |
87 | ### To autostart `swhkd` you can do one of two things
88 |
89 | 1. Add the commands from the ["Running"
90 | section](https://github.com/waycrate/swhkd#running) to your window managers
91 | configuration file.
92 | 1. Enable the [service
93 | file](https://github.com/waycrate/swhkd/tree/main/contrib/init) for your
94 | respective init system. Currently, only systemd and OpenRC service files
95 | exist and more will be added soon including Runit.
96 |
97 | ## Security
98 |
99 | We use a server-client model to keep you safe. The daemon (`swhkd` — privileged
100 | process) is responsible for listening to key events and running shell commands.
101 | The server (`swhks` — non-privileged process) is responsible for keeping a track of the
102 | environment variables and sending them to the daemon. The daemon
103 | uses these environment variables while running the shell commands.
104 | The daemon only runs shell commands that have been parsed from the config file and there is no way to
105 | run arbitrary shell commands. The server is responsible for only sending the environment variables to the daemon and nothing else.
106 | This separation of responsibilities ensures security.
107 |
108 | So yes, you're safe!

3 | # NAME
4 |
5 | swhkd - Hotkey daemon inspired by sxhkd written in Rust
6 |
7 | # SYNOPSIS
8 |
9 | *swhkd* [_flags_]
10 |
11 | # CONFIG FILE
12 |
13 | The config file goes in *~/.config/swhkd/swhkdrc* with a fallback to */etc/swhkd/swhkdrc*.
14 | More about the config file syntax in `swhkd(5)`
15 |
16 | # OPTIONS
17 |
18 | *-h*, *--help*
19 | Print help message and quit.
20 |
21 | *-V*, *--version*
22 | Print version information.
23 |
24 | *-c*, *--config*
25 | Set a custom config file path.
26 |
27 | *-C*, *--cooldown*
28 | Set a custom repeat cooldown duration. Default is 250ms. Most wayland
29 | compositors handle this server side however, either way works.
30 |
31 | *-d*, *--debug*
32 | Enable debug mode.
33 |
34 | *-D, --device*
35 | Manually set the keyboard devices to use. Can occur multiple times.
36 |
37 | # SIGNALS
38 |
39 | - Reload config file: `sudo pkill -HUP swhkd`
40 | - Pause Hotkey checking: `sudo pkill -USR1 swhkd`
41 | - Resume key checking: `sudo pkill -USR2 swhkd`

3 | # NAME
4 |
5 | swhkd - Hotkey daemon inspired by sxhkd written in Rust
6 |
7 | # CONFIG FILE
8 |
9 | - A global config can be defined in *~/.config/swhkd/swhkdrc*, with a
10 | fallback to */etc/swhkd/swhkdrc*. Swhkd attempts to look in your *$XDG_CONFIG_HOME*, failing which it defaults to *~/.config*.
11 | - A local config overrides the global one. Local configs should be placed in the root of the project.
12 | - The config file can also be specified with the *-c* flag.
13 |
14 | # ENVIRONMENT
15 |
16 | - The environment variables are now sourced using the SWHKS binary, running in the background.
17 | - The environment variables are then supplemented to the command that is to be run, thus emulating the
18 | environment variables in the default shell.
19 | - The commands are executed via *SHELL -c 'command'*, hence the environment is sourced from the default shell.
20 | - If the user wants to use a different set of environment variables, they can set the environment variables
21 | in the default shell or export the environment variables within a logged in instance of their shell before
22 | running the SWHKS binary.
23 |
24 | # SYNTAX
25 |
26 | The syntax of the configuration file is identical to sxhkd and builds upon it.
27 | More information about the syntax can be found from the official sxhkd documentation:
28 | https://man.archlinux.org/man/sxhkd.1, however a brief summary of it is provided below.
29 |
30 | Each line of the configuration file is interpreted as so:
31 | - If it is empty or starts with #, it is ignored.
32 | - If it starts with a space, it is read as a command.
33 | - Otherwise, it is read as a hotkey.
34 |
35 | For valid keys and modifiers, check *swhkd-keys(5)*
36 |
37 | # EXAMPLE
