How to preview :g commands

[AckslD]

Can this plugin be used to preview :g? For example lets say I have the buffer:

foo
bar
barx
foo
xbar

and I want to delete any line containing bar which could be done with :g/bar/d<CR>. However if I add the entry G = { cmd = 'g' } to the config of this plugin. It only previews the command on the current line when I type :G/bar/d, even though :g acts on all lines.

That's a nice usecase! I have now fixed a few bugs on the main branch (note that visualizing deletions won't work on main now, I'll get to that once I have finished work on the hl_improvements branch :D). Please try changing your command to G = { cmd = 'g' , hl_range = { 1, -1, kind = "absolute" } } (edit: it should be hl_range instead of range).

Thanks for a quick reply! I tried your suggestion but now I don't get any preview, but maybe that's related to deletions not working as you mentioned since :g/bar/d will only delete?

Sorry, my earlier fix was a bit too rushed 😄 I have now fixed several bugs related to the handling of ranges, could you try again with the latest commit? Highlights should now also work again and your other issue is hopefully resolved too (not tested though).

Seems to not have done it unfortunately, I'm getting the original behaviour for both this and #6 now.

Ok, for this issue, please change range to hl_range, that was a typo in my earlier comment. I reopened your other issue :)

Ah! Yes this works, thanks ❤️ 🚀

I noticed there was pretty bad performance when using your G command in large files. I have now added hl_range = { kind = "visible" } to only preview visible lines in the current buffer which speeds up things dramatically!

[AckslD]

Ah that's awesome!

This is really nice. Is there a way to also highlight the found patterns like :g does at first, before applying the command? @AckslD @smjonas
