Part of my neovim setup requires having the
black
python formatter
installed and callable. I install it with
pipx
so that I don't have
to manage a virtual environment and have it available everywhere. So
far this works well for me, if there are ever breaking changes I may
need to rethink this.
re-installing a bunch of things that are already installed can be quite a waste and really add up to my ansible run time, so for most of my ansible tasks that install a command like this I have been following this pattern.
-
check if the command is installed with
command -v <command> - register that step
- ignore if that step fails
-
add a
when: <xxx>_exists is failedcondition to the step that installs that command.
- name: check is black installed
shell: command -v black
register: black_exists
ignore_errors: yes
- name: install black
when: black_exists is failed
shell: pipx install black
