Possible hunk preview issue

[austincm]

I've recently upgraded to neovim 11.3 and the latest version of gitsigns and I'm noticing that I can only preview each "part" of a hunk. Is this intentional or did I find a bug?

For example, if I change a line and add a comment above it, that will stage as a single hunk and also show a single inline preview with both changes, but when I use the preview window, I have to view the mod as one preview for the line change and one preview for the new line.

This is probably because you have linematch in your diffopt.

linematch breaks up the hunks so they are more accurate.

[austincm]

Hmm
:lua print(vim.opt.diffopt.linematch) returns nil. I don't have any of those options modified.

Just to be clear, I'm talking about the little window that pops up when calling preview_hunk.

Not sure that's correct, vim.opt needs :get(). Try set diffopt?

[austincm]

Ah, thanks, I'm not very good at figuring out the internals of vim.

If I run set diffopt I see that it's set to the default (according to :help diffopt) value of diffopt=internal,filler,closeoff,linematch:40

The diffs I'm previewing are only a few lines.

Are you saying I want to remove the linematch item?

[austincm]

That did it. Thanks.

I just added vim.opt.diffopt = "internal,filler,closeoff" to my options config.

Looks like this is now the default value now. Should there be a note or config option or something? I think more people may have this issue in the future.

It's not really an issue, it's a feature. Linematch provides much more accurate diffs, though some people don't seem to like it.
