This is probably a better idea than using the getopt plugin? That way no extra plugin has to be installed, I think.

+1 for this feature

This issue is interesting to me. I agree that adding completions to Fish natively would be better than adding them through an external plugin.

To do that we have to add this feature to Fish directly. I see PR 179 has a template of what would be added. Is that still good or does it need to be modified to be added to Fish?

I don't think it needs to be added directly to fish. I think you just need to provide the completions file to be loaded.

It's been a long long time since I looked at this tho, heh

It doesn't need to be added Fish, but it would be the best way because it means the user doesn't have to make any effort.

The other way would be add a command to colorls that copies the completions to $HOME/.config/fish/completions/.

Any of the two seem cleaner than adding an external plugin like getopt, as suggested.
