"fzf <command> <items command> [<fzf args> <extra commands>]: generic fzf command.
This command can be used to create new fzf wrappers for various Kakoune or external
features. More about arguments:
<command>:
The <command> is a Kakoune command that should be used after fzf returns some result.
For example to open file chooser we can call fzf with `edit` as a command:
'fzf %{edit} %{<items command>}'
After choosing one or more files in fzf, <command> will be used with each of them.
<items command>
This is the shell command that is used to provide list of values to fzf. It can be
any command that provides newline separated list of items, which is then piped to fzf.
<fzf args>
These are additional flags for fzf program, that are passed to it. You can check them
in fzf manual.
<extra commands>
This is extra commands that are preformed after fzf finishes and main command was
executed. This can be used to invoke fzf back, like in fzf-cd command, or to execute
any other Kakoune command that is meaningfull in current situation. This is more is
a workaround of problem with executing composite commands, where fzf result should
be in the middle of the command and may be changed or removed it further versions.
If you want to develop a module with fzf command, feel free to check for existing
module implementations in 'rc/fzf-modules' directory." \
