helix key bindings for fish
Dependencies: fish >= 3.6², GNU tools¹, perl.
functions directory as ~/.config/fish/functions.fish_helix_key_bindings.To undo, run fish_default_key_bindings.
¹ Should work with POSIX, but untested. Report any issues.
² fish >= 3.4 is sort of good enough. Clone fish-helix fish3.4 branch.
run-tests scriptfish_helix_command function provides some helix-like actions. Use it for custom bindings.
When defining your own bindings using fish_helix_command, be aware that it can break stuff sometimes.
It is safe to define a binding consisting of a lone call to fish_helix_command. Calls to other functions and executables are allowed along with it, granted they don't mess with fish's commandline buffer.
Mixing multiple fish_helix_commandline and commandline calls in one binding MAY trigger issues. Nothing serious, but don't be surprised. Just test it.
