Configuration guide
Link to the appropriate configuration guide version: guide link.
Known issue(s)
- Windows: keypad Enter (
kprt) and potentially other keys in the extended scancode range do not output correctly with the defaultkanata.exebinary. Use winiov2 instead.- Potential fix: #1321
Changelog (since v1.6.1)
BREAKING FIX: On Linux, mouse device auto-grabbing will happen only if mouse buttons are mapped in defsrc. This is breaking if all of the following apply:
- you rely on auto-grabbing
- you use a mouse with keyboard actions for kanata-relevant actions
- your mouse isn't identified as also being a keyboard
- you do not have any mouse button defined in defsrc
BEHAVIOUR CHANGE: include no longer errors on missing files.
Change log
Added: O-(...) for any-order overlapping keys in sequences.
Added: conditional configuration using environment variables via (environment (name val) ...)
Added: allow double-quotes within strings by adding Rust-style strings r#"<content>"#. Potentially breaking, but seems doubtful that anyone has a good reason to be doing this
Added: --log-layer-changes flag to override false configuration temporarily for testing
Added: parse numbers as a delay (unit milliseconds) for cmd-output-keys
Added: unmod can accept a modifier list as the first parameter to selectively undo only some modifiers
Added: option to eagerly release override output to help with some use cases
Added: cmd-log

Added(Windows): capability to use Kanata as a library for AHK
Added(Windows): GUI tray app (gui variants of the executable)
Added(Windows): JIS key mappings

Added(Linux): linux-output-device-bus-type for defcfg
Added(Linux): linux-device-detect-mode for defcfg
Added(macOS): unicode action is now implemented
Added(macOS): mouse actions are now implemented (some bugs still exist)
Fixed: chordsv2 now eagerly activates tap-hold-press|release
Fixed: chordsv2 preserves event release order
Fixed: chordsv2 configuration errors point to precise location
Fixed: chordsv2 configuration causes error on duplicate input keys where before it would silently overwrite earlier configurations
Fixed: one-shot activations from within chordsv2 are preserved
Fixed: keep other macros around when another macro completes
Fixed: swap incorrect unmod with custom mod keys for alt/meta
Fixed: block-unmapped-keys now only blocks unspecified actions, where before it would block explicitly transparent keys as well
Sample configuration file
The attached kanata.kbd file is tested to work with the current version. The one in the main branch of the repository may have extra features that are not supported in this release.
Windows
Instructions
NOTE: All Linux binaries are compiled for x86-64 architectures only.
Download kanata.exe. Optionally, download kanata.kbd. With the two files in the same directory, you can double-click the exe to start kanata. Kanata does not start a background process, so the window needs to stay open after startup. See this discussion for tips to run kanata in the background.
You need to run kanata.exe via cmd or powershell to use a different configuration file:
kanata.exe --cfg <cfg_file>
NOTE: The kanata_winIOv2.exe variant contains an experimental breaking change that fixes an issue where the Windows LLHOOK+SendInput version of kanata does not handle defsrc consistently compared to other versions and other operating systems. This variant will be of interest to you for any of the following reasons:
- you are a new user
- you are a cross-platform user
- you use multiple language layouts within Windows and want kanata to handle the key positions consistently
This variant contains the same output change as in the scancode variant below, and also changes the input to also operate on scancodes.
The gui variants only use the winiov2 I/O mechanism.
NOTE: The kanata_legacy_output.exe variant has the same input defsrc handling as the standard kanata.exe file. It uses the same output mechanism as the standard kanata.exe variant in version 1.6.1 and earlier. In other words the formerly experimental_scancode variant is now the default binary. The non-legacy variants contain changes for an issue; the fix is omitted from this legacy variant. The legacy variant is included in case issues are found with the new output mechanism.
Linux
Instructions
NOTE: All Windows binaries are compiled for x86-64 architectures only.
Download kanata.
Run it in a terminal and point it to a valid configuration file. Kanata does not start a background process, so the window needs to stay open after startup. See this discussion for how to set up kanata with systemd.
chmod +x kanata # may be downloaded without executable permissions
sudo ./kanata --cfg <cfg_file>`
To avoid requiring sudo, follow the instructions here.
macOS
Instructions
WARNING: feature support on macOS is limited.
For macOS 11 and newer:
- Install the Karabiner VirtualHiDDevice Driver.
To activate it:
/Applications/.Karabiner-VirtualHIDDevice-Manager.app/Contents/MacOS/Karabiner-VirtualHIDDevice-Manager activate
For macOS 10 and older:
- Install the Karabiner kernel extension.
After installing the appropriate driver for your OS
Download a kanata_macos variant.
Run it in a terminal and point it to a valid configuration file. Kanata does not start a background process, so the window needs to stay open after startup.
Example
chmod +x kanata_macos_arm64 # may be downloaded without executable permissions
sudo ./kanata_macos_arm64 --cfg <cfg_file>`
cmd_allowed variants
Explanation
The binaries with the name cmd_allowed are conditionally compiled with the cmd action enabled.
Using the regular binaries, there is no way to get the cmd action to work. This action is restricted behind conditional compilation because I consider the action to be a security risk that should be explicitly opted into and completely forbidden by default.
wintercept variants
Explanation and instructions
Warning: known issue
This issue in the Interception driver exists: oblitum/Interception#25. This will affect you if you put your PC to sleep instead of shutting it down, or if you frequently plug/unplug USB devices.
Description
These variants use the Interception driver instead of Windows hooks. You will need to install the driver using the release or from the copy in this repo. The benefit of using this driver is that it is a lower-level mechanism than Windows hooks. This means kanata will work in more applications.
Steps to install the driver
- extract the
.zip - run a shell with administrator privilege
- run the script
"command line installer/install-interception.exe" - reboot
Additional installation steps
The above steps are those recommended by the interception driver author. However, I have found that those steps work inconsistently and sometimes the dll stops being able to be loaded. I think it has something to do with being installed in the privileged location of system32\drivers.
To help with the dll issue, you can copy the following file in the zip archive to the directory that kanata starts from: Interception\library\x64\interception.dll.
E.g. if you start kanata from your Documents folder, put the file there:
C:\Users\my_user\Documents\
kanata_wintercept.exe
kanata.kbd
interception.dll
kanata_passthru.dll
Explanation and instructions
The Windows kanata_passthru.dll file allows using Kanata as a library within AutoHotkey to avoid conflicts between keyboard hooks installed by both. You can channel keyboard input events received by AutoHotkey into Kanata's keyboard engine and get the transformed keyboard output events (per your Kanata config) that AutoHotkey can then send to the OS.
To make use of this, download kanata_passthru.dll, then the simulated_passthru_ahk folder with a brief example, place the dll there, open kanata_passthru.ahk to read what the example does and then double-click to launch it.
