How to use `helm diff completion bash`

[tanvp112]

Hi,

After issue the command source <(helm diff completion bash), I expect to have command line completion when using helm diff [tab], but the command is not expanded nor provide list of options. The mean time helm command itself can do completion with no issue.

How to make bash completion works for helm-diff?

Thanks!

does it work fine in other helm plugins? @tanvp112

I only use helm-diff & dt only. dt doesn't support completion bash in the first place.

I got the same problem in RaspiOS ARMv7 too. I also tried to installed it (source in .bashrc), it didn't work.

$ helm diff completion bash
# bash completion V2 for diff                                 -*- shell-script -*
...
if [[ $(type -t compopt) = "builtin" ]]; then
    complete -o default -F __start_diff diff
else
    complete -o default -o nospace -F __start_diff diff
fi

# ex: ts=4 sw=4 et filetype=sh

$ complete -p diff
complete -F __start_diff diff

Looks like it's adding the completion for diff, not helm diff

@yxxhero to the rescue?

I came upon this issue on the search for completion for this plugin, did you know about helm/helm#7468?

As far as I can tell this should allow complection via the normal helm completion $SHELL command also for plugins
