Inline diffs

[caenrique]

Describe the solution you'd like
Same as preview_hunk_inline but for the whole file

Describe alternatives you've considered

• Using normal diff view in a split
• Using plugins for diffs like DiffView.nvim
• viewing diffs inline a hunk at a time

I think the inline diff for hunks is awesome and I would love to be able to do it for the whole file in a single toggle

Is this not possible in the current implementation? I'm trying to find the way how to do it, but seems it's not possible :(

UPD.
I found this issue in vim-fugitive repo. Contributor of this repository says that it's not possible
tpope/vim-fugitive#1957

It doesn't support it built in, but plugins are able to implement it.

Gitsigns already supports viewing a diff inline for a single hunk, that just needs to be extended for the whole buffer.

[lewis6991]

Just looked into this and it's more complicated than I anticipated.

Basically, In order to achieve syntax highlighting for deleted hunks, Gitsigns creates some blank virtual_lines and then places a floating window on top. Since this floating window is removed when the cursor is moved, we currently don't have to worry about it going off screen, or generally have to manage it much.

One possible solution would be to re-implement this without the floating window and grab all the highlights manually.

Isn't this already supported?

Just create a binding that toggles the following commands:

toggle_deleted
toggle_linehl
toggle_word_diff

[lewis6991]

That's one way of achieving this. However toggle_deleted doesn't show syntax highlighting unlike preview_hunk_inline.

Would love to have this.
Currently using toggle_deleted as the alternative for how mini-diff inlines these changes but don't want to use a whole another plugin for just this.

@lewis6991 just came across this

@fredrikaverpil Hey, I saw that you've implemented this. I tried out your branch and it works perfectly. Are you planning to open a PR? Would love to see this merged upstream :)

[fredrikaverpil]

@twio142 I wanted to run this for myself a bit and see if it holds up, before potentially submitting a PR. So far, I think it works well for my use cases. Happy to hear you like it too!

I can of course open a PR, but @lewis6991 I'm not sure if this was the kind of implementation you had in mind?

[lewis6991]

No PRs on this please. I'll implement it myself eventually.

It would be great if anyone will implement a Zed-style diff in a reusable way, to let other plugins just use it.
