I'd like to write a zsh completion for pytest.Where do I Start? I'm using oh-my-zsh.in .zshrc:fpath=($HOME/.mycompletions $fpath)autoload -U compinit && compinit -uin $HOME/.mycompletions/_pytest:#compdef pytest_pytest(){    cur=${COMP_WORDS[COMP_CWORD]}    COMPREPLY=(`pytestcomplete ${cur} 2>/dev/null`)}complete -o nospace -F _pytest py.testIs this correct so far?Now I only need to write the pytestcomplete script.What should the Return values Look like? How can I hand over to the script which parts have been completed?I.e. if a user does py.test<TAB> it should complete files first.If one does py.test tests/my.test.py<TAB> it should complete class names.If one does py.test tests/my.test.py::TestClass<TAB> it should complete method names.To get the info out of pytest, one would use --collect-only. The only problem at the moment is the back and forth between zsh and the completion script.And can this be done like this or do I need to write a oh-my-zsh plugin?
