How to load tabtab completion?

I would like to enable tabtab completion for pnpm with znap, but I don't see a way of loading a custom zsh completion script.

• https://pnpm.io/completion
• https://github.com/pnpm/tabtab

pnpm install-completion zsh creates two new files:

• ~/.config/tabtab/zsh/__tabtab.zsh and
• ~/.config/tabtab/zsh/pnpm.zsh.

It then goes on to modify ~/.zshrc (and if it doesn't exist, first creates it).

This (modifying a user's dotfiles) is a big NO-NO in Unix land! You should file a bug report with pnpm about this. Plus, if your $ZDOTDIR is set to something else than $HOME, this won't even enable pnpm completion (because then, $ZDOTDIR/.zshrc is read at startup, instead of ~/.zshrc.

What pnpm really should be doing is to install its completion function to /usr/local/share/zsh/site-functions, as I described here on Stack Overflow. You can include that link your bug report. If they do it the way I described, then there is no need to modify the user's dotfiles, because the completion function will get picked up by compinit automatically.

You can discard ~/.config/tabtab/zsh/__tabtab.zsh and the changes to ~/.zshrc. Instead, just add

source $XDG_CONFIG_HOME/tabtab/zsh/pnpm.zsh

to your .zshrc file, after sourcing Znap.

In short: The way pnpm installs completions is incorrect. They really need to change it and there's no way you can manage this with Znap.

Many thanks for the detailed explanation! This makes a lot more sense. I hate it when installer modified any of my conf, so yes, reasonable.

Once I get time again for my Zsh stuff I will fill an issue on pnpm. But I guess tabtab is doing it wrong from beginning.
