Languages

The programming languages listed on this page have built-in support in kakoune through the use of rc files.

This encompass such common operations as highlighting, indenting, tagging, building, debugging, linting…

Columns in the following table:

• Name: points to the source file of the related kak script.
• Alt File: the script creates an alt command to switch between related buffers, for example switching between .c and .h files in C.
• lintcmd: the language can be linted by this command external tool.
• formatcmd: the language can be formatted through this external command, but you need to plug in explicitly in your kakrc. Example with rust using a hook (note that this hook is added upstream):

hook global WinSetOption filetype=rust %{
  set window formatcmd 'rustfmt'
}
