[Feature Request] Handle pytest command the same as python about fzf

[junegunn]

I'm assuming you're a bash user, and you can set it up as explained in https://github.com/junegunn/fzf?tab=readme-ov-file#supported-commands

I know, what I suggested is to add it to the built-in command completions.

[junegunn]

I see, but if we add more commands to the default list, the time it takes to load the script increases accordingly, and it affects the other users who don't really use pytest (which I'm one of them), so I'm reluctant to grow the default list beyond a set of universal tools.

[DavideCanton]

I see, but then I don't understand why I'm having python and java already registered, since I don't use java either.

[junegunn]

Yeah, it's already not ideal, so let's not make it worse.

[junegunn]

Having said that, maybe we could provide path as the default completion.

complete -D -F _fzf_path_completion -o default -o bashdefault 2> /dev/null

Hmm, unfortunately, this will likely break bash-completion, which sets its dynamic completion loader as the default completion function.

https://github.com/scop/bash-completion/blob/2dab63379b90619f93873976944f4f9ad338dc0d/bash_completion#L3260-L3271

[junegunn]

__fzf_default_completion() {
  __fzf_generic_path_completion _fzf_compgen_path "-m" "" "$@"
  if [[ $? -eq 124 ]]; then
    _fzf_setup_completion path "$1"
    return 124
  fi
}

complete -D -F __fzf_default_completion -o default -o bashdefault 2> /dev/null

This version works slightly better, that it handles dynamic completion loader.

# No completion is defined
complete | grep pytest

# Fuzzy completion works
pytest **<tab>

# Regular completion; triggers dynamic completion loader
pytest <tab>

# Completion function for pytest is loaded
complete | grep pytest
  # complete -F _comp_cmd_pytest py.test
  # complete -F _comp_cmd_pytest py.test-3
  # complete -F _comp_cmd_pytest py.test-2
  # complete -F _comp_cmd_pytest pytest-3
  # complete -F _comp_cmd_pytest pytest-2
  # complete -F _fzf_path_completion pytest

# Fuzzy completion still works
pytest **<tab>

# Regular completion also works
pytest <tab>

# However, fuzzy completion for pytest-2, pytest-3, etc stops working
pytest-2 **<tab>
