kanata.kbd

#|
This is a sample configuration file that showcases every feature in kanata.
A more detailed and less terse configuration guide is found here:

    https://github.com/jtroo/kanata/blob/main/docs/config.adoc

Other configuration samples are found here:

    https://github.com/jtroo/kanata/tree/main/cfg_samples

If anything is confusing or hard to discover, please file an issue or
contribute a pull request to help improve the document.

Since it may be important for you to know, pressing and holding all of the
three following keys together at the same time will cause kanata to exit:

  Left Control, Space, Escape

This is for the physical key input rather than after any remappings
that are done by kanata.

;; Single-line comments are prefixed by double-semicolon. A single semicolon
;; is parsed as the keyboard key. Comments are ignored for the configuration
;; file.

#|
A multi-line comment block begin with an octothorphe followed by a pipe: `#|`.
To end the multi-line comment block, have a pipe followed by an octothorpe,
like the following sequence with the colon removed: `|:#`. The actual two
character sequence is not used because it would end this multi-line comment
block and cause a parsing error.

This configuration language is Lisp-like and uses S-Expression syntax.
If you're unfamiliar with Lisp, don't be alarmed. The maintainer jtroo is
also unfamiliar with Lisp. You don't need to know Lisp in-depth to
be able to configure kanata.

If you follow along with the examples, you should be fine. Kanata should
also hopefully have helpful error messages in case something goes wrong.
If you need help, please feel welcome to ask in the GitHub discussions.

;; One defcfg entry may be added if desired. This is used for configuration
;; key-value pairs that change kanata's behaviour at a global level.
;; All defcfg options are optional.
(defcfg
  ;; Your keyboard device will likely differ from this. I believe /dev/input/by-id/
  ;; is preferable; I recall reading that it's less likely to change names on you,
  ;; but I didn't find any keyboard device in there in my VM. If you are on Linux
  ;; and omit this entry, kanata will try to attach to every device found on your
  ;; system that seems like a keyboard.
  ;; linux-dev /dev/input/by-path/platform-i8042-serio-0-event-kbd

  ;; If you want to read from multiple devices, separate them by `:`.
  ;; linux-dev /dev/input/<dev1>:/dev/input/<dev2>
  ;;
  ;; If you have a colon in your device path, add a backslash before it so that
  ;; kanata does not parse it as multiple devices.
  ;; linux-dev /dev/input/path-to\:device

  ;; Alternatively, you can use list syntax, where both backslashes and colons
  ;; are parsed literally. List items are separated by spaces or newlines.
  ;; Using quotation marks for each item is optional, and only required if an
  ;; item contains spaces.
  ;; linux-dev (
  ;;   /dev/input/by-path/pci-0000:00:14.0-usb-0:1:1.0-event
  ;;   /dev/input/by-id/usb-Dell_Dell_USB_Keyboard-event-kbd
  ;; )

  ;; The linux-dev-names-include entry is parsed identically to linux-dev. It
  ;; defines a list of device names that should be included. This is only
  ;; used if linux-dev is omitted.
  ;; linux-dev-names-include device-1-name:device\:2\:name

  ;; The linux-dev-names-exclude entry is parsed identically to linux-dev. It
  ;; defines a list of device names that should be excluded. This is only
  ;; used if linux-dev is omitted. This and linux-dev-names-include are not
  ;; mutually exclusive but in practice it probably makes sense to only use
  ;; one of them.
  ;; linux-dev-names-exclude device-1-name:device\:2\:name

  ;; By default, kanata will crash if no input devices are found. You can change
  ;; this behaviour by setting `linux-continue-if-no-devs-found`.
  ;;
  ;; linux-continue-if-no-devs-found yes

  ;; On Linux, you can ask kanata to run `xset r rate <delay> <rate>` on startup
  ;; and on live reload via the config below. The first number is the delay in ms
  ;; and the second number is the repeat rate in repeats/second.
  ;;
  ;; linux-x11-repeat-delay-rate 400,50

  ;; On linux, you can ask kanata to label itself as a trackpoint. This has several
  ;; effects on libinput including enabling middle mouse button scrolling and using
  ;; a different acceleration curve. Otherwise, a trackpoint intercepted by kanata
  ;; may not behave as expected.
  ;;
  ;; If using this feature, it is recommended to filter out any non-trackpoint
  ;; pointing devices using linux-only-linux-dev-names-include,
  ;; linux-only-linux-dev-names-exclude or linux-only-linux-dev to avoid changing
  ;; their behavior as well.
  ;;
  ;; linux-use-trackpoint-property yes

  ;; Unicode on Linux works by pressing Ctrl+Shift+U, typing the unicode hex value,
  ;; then pressing Enter. However, if you do remapping in userspace, e.g. via
  ;; xmodmap/xkb, the keycode "U" that kanata outputs may not become a keysym "u"
  ;; after the userspace remapping. This will be likely if you use non-US,
  ;; non-European keyboards on top of kanata. For unicode to work, kanata needs to
  ;; use the keycode that outputs the keysym "u", which might not be the keycode
  ;; "U".
  ;;
  ;; You can use `evtest` or `kanata --debug`, set your userspace key remapping,
  ;; then press the key that outputs the keysym "u" to see which underlying keycode
  ;; is sent. Then you can use this configuration to change kanata's behaviour.
  ;;
  ;; Example:
  ;;
  ;;   linux-unicode-u-code v

  ;; Unicode on Linux terminates with the Enter key by default. This may not work in
  ;; some applications. The termination is configurable with the following options:
  ;;
  ;; - `enter`
  ;; - `space`
  ;; - `enter-space`
  ;; - `space-enter`
  ;;
  ;; Example:
  ;;
  ;;   linux-unicode-termination space

  ;; There is an optional configuration entry for Windows to help mitigate strange
  ;; behaviour of AltGr if your layout uses that. Uncomment one of the items below
  ;; to change what kanata does with the key.
  ;;
  ;; For more context, see: https://github.com/jtroo/kanata/issues/55.
  ;;
  ;; windows-altgr cancel-lctl-press ;; remove the lctl press that comes as a combo with ralt
  ;; windows-altgr add-lctl-release  ;; add an lctl release when ralt is released
  ;;
  ;; NOTE: even with these workarounds, putting lctl+ralt in your defsrc may
  ;; not work too well with other applications that use WH_KEYBOARD_LL.
  ;; Known applications with issues: GWSL/VcXsrv

  ;; Enable kanata to execute commands.
  ;;
  ;; I consider this feature a hazard so it is conditionally compiled out of
  ;; the default binary.
  ;;
  ;; This is dangerous because it allows kanata to execute arbitrary commands.
  ;; Using a binary compiled with the cmd feature enabled, uncomment below to
  ;; enable command execution:
  ;;
  ;; danger-enable-cmd yes

  ;; Enable processing of keys that are not in defsrc.
  ;; This is useful if you are only mapping a few keys in defsrc instead of
  ;; most of the keys on your keyboard. Without this, the tap-hold-release and
  ;; tap-hold-press actions will not activate for keys that are not in defsrc.
  ;;
  ;; The reason this is not enabled by default is because some keys may not
  ;; work correctly if they are intercepted. E.g. rctl/altgr on Windows; see the
  ;; windows-altgr configuration item above for context.
  ;;
  ;; process-unmapped-keys yes

  ;; We need to set it to yes in this kanata.kbd example config to allow the use of __ and ___
  ;; in the deflayer-custom-map example below in the file
  process-unmapped-keys yes

  ;; Disable all keys not mapped in defsrc.
  ;; Only works if process-unmapped-keys is also yes.
  ;; block-unmapped-keys yes

  ;; Intercept mouse buttons for a specific mouse device.
  ;; The intended use case for this is for laptops such as a Thinkpad, which have
  ;; mouse buttons that may be useful to activate kanata actions with. This only
  ;; works with the Interception driver.
  ;;
  ;; To know what numbers to put into the string, you can run the
  ;; kanata-wintercept variant with this defcfg item defined with random numbers.
  ;; Then when a button is first pressed on the mouse device, kanata will print
  ;; its hwid in the log; you can then copy-paste that into this configuration
  ;; entry. If this defcfg item is not defined, the log will not print.
  ;;
  ;; windows-interception-mouse-hwid "70, 0, 90, 0, 20"

  ;; There is also a list version of windows-interception-mouse-hwid:
  ;;
  ;; windows-interception-mouse-hwids (
  ;;   "70, 0, 60, 0"
  ;;   "71, 0, 62, 0"
  ;; )

  ;; that allows intercepting only some connected keyboards.
  ;; Use similarly to mouse-hwid above.

  ;; Transparent keys on layers will delegate to the corresponding defsrc key
  ;; when found on a layer activated by `layer-switch`. This config entry
  ;; changes the behaviour to delegate to the action of the first layer,
  ;; which is the layer active upon startup, that is in the same position.
  ;;
  ;; delegate-to-first-layer yes

  ;; This config entry alters the behavior of movemouse-accel actions.
  ;; By default, this setting is disabled - vertical and horizontal
  ;; acceleration are independent. Enabling this setting will emulate QMK mouse
  ;; move acceleration behavior, i.e. the acceleration state of new mouse
  ;; movement actions are inherited if others are already being pressed.
  ;;
  ;; movemouse-inherit-accel-state yes

  ;; This config entry alters the behavior of movemouseaccel actions.
  ;; This makes diagonal movements simultaneous to mitigate choppiness in
  ;; drawing apps, if you're using kanata mouse movements to draw for
  ;; whatever reason.
  ;;
  ;; movemouse-smooth-diagonals yes

  ;; This configuration allows you to customize the length limit on dynamic macros.
  ;; The default limit is 128 keys.
  ;;
  ;; dynamic-macro-max-presses 1000

  ;; This configuration makes multiple tap-hold actions that are activated near
  ;; in time expire their timeout quicker. Without this, the timeout for the 2nd
  ;; tap-hold onwards will start from 0ms after the previous tap-hold expires.
  ;;
  concurrent-tap-hold yes

  ;; This configuration makes the release of one-shot-press and of the tap in a tap-hold
  ;; by the defined number of milliseconds (approximate).
  ;; The default value is 5.
  ;; While the release is delayed, further processing of inputs is also paused.
  ;; This means that there will be a minor input latency impact in the mentioned scenarios.
  ;; The reason for this configuration existing is that some environments
  ;; do not process the scenarios correctly due to the rapidity of the release.
  ;; Kanata does send the events in the correct order,
  ;; so the fault is more in the environment, but kanata provides a workaround anyway.
  rapid-event-delay 5

  ;; This setting defaults to yes but can be configured to no to save on
  ;; logging. However, if --log-layer-changes is passed as a command line
  ;; argument, a "no" in the configuration file will be overridden and layer
  ;; changes will be logged.
  ;;
  ;; log-layer-changes no

  ;; This configuration will press and then immediately release the non-modifier key
  ;; as soon as the override activates, meaning you are unlikely as a human to ever
  ;; release modifiers first, which can result in unintended behaviour.
  ;;
  ;; The downside of this configuration is that the non-modifier key
  ;; does not remain held which is important to consider for your use cases.
  override-release-on-activation yes

;; deflocalkeys-* enables you to define and use key names that match your locale
;; by defining OS code number mappings for that character.
;;
;; There are five variants of deflocalkeys-*:
;; - deflocalkeys-win

;; - deflocalkeys-wintercept
;; - deflocalkeys-linux
;; - deflocalkeys-macos
;;
;; Only one of each deflocalkeys-* variant is allowed. The variants that are
;; not applicable will be ignored, e.g. deflocalkeys-linux and deflocalkeys-wintercept

  ;;
  ;; tap-hold parameter order:
  ;; 1. tap timeout
  ;; 2. hold timeout
  ;; 3. tap action
  ;; 4. hold action
  ;;
  ;; The hold timeout is the number of milliseconds after which the hold action
  ;; will activate.
  ;;
  ;; The tap timeout is best explained in a roundabout way. When you press and
  ;; hold a standard key on your keyboard (e.g. 'a'), your operating system will
  ;; read that and keep sending 'a' to the active application. To be able to
  ;; replicate this behaviour with a tap-hold key, you must press-release-press
  ;; the key within the tap timeout window (number is milliseconds). Simply
  ;; holding the key results in the hold action activating, which is why you
  ;; need to double-press for the tap action to stay pressed.
  ;;
  ;; There are two additional versions of tap-hold available:
  ;; 1. tap-hold-press: if there is a key press, the hold action is activated
  ;; 2. tap-hold-release: if there is a press and release of another key, the
  ;; hold action is activated
  ;;
  ;; These versions are useful if you don't want to wait for the whole hold
  ;; timeout to activate, but want to activate the hold action immediately
  ;; based on the next key press or press and release of another key. These
  ;; versions might be great to implement home row mods.
  ;;
  ;; If you come from kmonad, tap-hold-press and tap-hold-release are similar
  ;; to tap-hold-next and tap-hold-next-release, respectively. If you know
  ;; the underlying keyberon crate, tap-hold-press is the HoldOnOtherKeyPress
  ;; and tap-hold-release is the PermissiveHold configuration.

  ;; Having a cmd action in your configuration without explicitly enabling
  ;; `danger-enable-cmd` **and** using the cmd-enabled executable will make
  ;; kanata refuse to load your configuration. The aliases below are commented
  ;; out since commands aren't allowed by this configuration file.
  ;;
  ;; Note that the parameters to `cmd` are executed directly as opposed to
  ;; passed to a shell. So for example, `~` and `$HOME` would not refer
  ;; to your home directory on Linux.
  ;;
  ;; You can use:
  ;; `cmd bash -c "your_stuff_here"` to run your command inside of bash.
  ;;
  ;; cm1 (cmd bash -c "echo hello world")
  ;; cm2 (cmd rm -fr /tmp/testing)

  ;; One variant of `cmd` is `cmd-log`, which lets you control how
  ;; running command, stdout, stderr, and execution failure are logged.
  ;;
  ;; The command takes two extra arguments at the beginning `<log_level>`,
  ;; and `<error_log_level>`. `<log_level>` controls where the name
  ;; of the command is logged, as well as the success message and command 
  ;; stdout and stderr.
  ;;
  ;; `<error_log_level>` is only used if there is a failure executing the initial
  ;; command. This can be if there is trouble spawning the command, or
  ;; the command is not found. This means if you use `bash -c "thisisntacommand"`, as
  ;; long as bash starts up correctly, nothing would be logged to this channel, but
  ;; something like `thisisntacommand` would be.
  ;;
  ;; The log level can be `debug`, `info`, `warn`, `error`, or `none`.
  ;;
  ;; cmd-log info error bash -c "echo these are the default levels"
  ;; cmd-log none none bash -c "echo nothing back in kanata logs"
  ;; cmd-log none error bash -c "only if command fails"
  ;; cmd-log debug debug bash -c "echo log, but require changing verbosity levels"
  ;; cmd-log warn warn bash -c "echo this probably isn't helpful"

  ;; Another variant of `cmd` is `cmd-output-keys`. This reads the output
  ;; of the command and treats it as an S-Expression, similarly to `macro`.
  ;; However, only delays, keys, chords, and chorded lists are supported.
  ;; Other actions are not.
  ;; 
  ;; bash: type date-time as YYYY-MM-DD HH:MM
  ;; cmd-output-keys bash -c "date +'%F %R' | sed 's/./& /g' | sed 's/:/S-;/g' | sed 's/\(.\{20\}\)\(.*\)/\(\1 spc \2\)/'"

;; Vim-style leader-key sequences. Activate a fakekey-tap by pressing a "leader"
;; key and then a sequence of characters.
;; See: https://github.com/jtroo/kanata/issues/97
;;
;; You can add an entry to defcfg to change the sequence timeout (default is 1000):
;;     sequence-timeout <number(ms)>
;;
;; If you want multiple timeouts with different leaders, you can also activate the
;; sequence action:
;;     (sequence <timeout>)
;; This acts like `sldr` but uses a different timeout.
;;
;; There is also an option to customize the key sequence input mode. Its default
;; value when not configured is `hidden-suppressed`.
;;
;; The options are:
;;
;; - `visible-backspaced`: types sequence characters as they are inputted. The
;;   typed characters will be erased with backspaces for a valid sequence termination.
;; - `hidden-suppressed`: hides sequence characters as they are typed. Does not
;;   output the hidden characters for an invalid sequence termination.
;; - `hidden-delay-type`: hides sequence characters as they are typed. Outputs the
;;   hidden characters for an invalid sequence termination either after either a
;;   timeout or after a non-sequence key is typed.
;;
;; For `visible-backspaced` and `hidden-delay-type`, a sequence leader input will
;; be ignored if a sequence is already active. For historical reasons, and in case
;; it is desired behaviour, a sequence leader input using `hidden-suppressed` will
;; reset the key sequence.

;; Input chording.
;;
;; Not to be confused with output chords (like C-S-a or the chords layer
;; defined above), these allow you to perform actions when a combination of
;; input keys (a "chord") are pressed all at once (order does not matter).
;; Each combination/chord can perform a different action, allowing you to bind
;; up to `2^n - 1` different actions to just `n` keys.
;;
;; Each `defchords` defines a named group of such chord-action pairs.
;; The 500 is a timeout after which a chord triggers if it isn't triggered by a
;; key release or press of a non-chord key before the timeout expires.
;; If a chord is not defined, no action will occur when it is triggered but the
;; keys used to input it will be consumed regardless.
;;
;; Each pair consists of the keys that make up a given chord in the parenthesis
;; followed by the action that should be executed when the given chord is
;; pressed.
;; Note that these keys do not directly correspond to real keys and are merely
;; arbitrary labels that make sense within the context of the chord.
;; They are mapped to real keys in layers by configuring the key in the layer to
;; map to a `(chord name key)` action (like those in the `defalias` below) where
;; `name` is the name of the chords group (here `binary`) and `key` is one of the
;; arbitrary labels of the keys in a chord (here `1`, `2`, `4` and `8`).
;;
;; Note that it is perfectly valid to nest these `chord` actions that enter
;; "chording mode" within other actions like `tap-dance` and that will work as
;; one would expect.
;; However, this only applies to the first key used to enter "chording mode".
;; Once "chording mode" is active, all other keys will be directly handled by
;; "chording mode" with no regard for wrapper actions; e.g. if a key is pressed
;; and it maps to a tap-hold with a chord as the hold action within, that chord
;; key will immediately activate instead of the key needing to be held for the
;; timeout period.
;;
;; The action executed by a chord (the right side of the chord-action pairs) may
;; be any regular or advanced action, including aliases. They currently cannot
;; however contain a `chord` action.
