How to manually load zsh completion definition?

[lazywei]

I want to load the completion from a non-canonical repo:
https://github.com/facebook/sapling/blob/main/eden/scm/contrib/zsh_completion

Is there a way to manually load a file that contains the completion definitions? I tried to add this to $HOME/.local/share/zsh/site-functions but it doesn't seem to work.

Add the following to your .zshrc file:

znap clone facebook/sapling
znap fpath _hg '< ~[facebook/sapling]/eden/scm/contrib/zsh_completion'

Got it, thank you!

Can I request a mode/option of zsh-snap to let it not do anything about zsh's existing comp system?

It seems to do some magic which I don't understand and it seems the "normal" way of using fpath/compdef/compdump does not work when using zsh-snap. This is a concern for me because other people's completion code (by calling compdef) written for "normal" zsh does not work for me.

It should work with other people's completion code. At least it works for me. Can you give me a reproducible test case?
