Icon Placement Right

[alex-courtis]

Can this functionality be implemented utilising API?
No, it's internal behaviour.

Describe the solution you'd like
Show icons: git, diagnostic, modified at the far right side of the tree.

Describe alternatives you've considered
Right sign column, not possible.

Additional context
#2348

[alex-courtis]

Requires #1510

[alex-courtis]

Possible values: "right" "end" "rightest"

Silently move placement from renderer.icons to git modified `diagnostics.

I currently know nothing about how this plugin renders nor writing complex lua plugin, so I'm sorry but still not able to make a PR to implement this feature. The only thing I know is that this may be implemented by vim.api.nvim_buf_set_extmark. If nobody makes PR, will you or when will you implement it by yourself?

[alex-courtis]

This issue is open and is a candidate for implementation, however will likely only be implemented when a kind contributor builds it.

@alex-courtis If you still have not picked that up, I think I can work on it.

[alex-courtis]

That would be fantastic @mr2rm !

I have been wanting this one for a while.

I've just started working on this issue. I came up with the idea to add a new option to renderer.icons which only applies to all the placements with an after value. If implemented like this, we would have more flexibility to place some of the icons in the before position or on the sign column. I would suggest renderer.icons.after_alignment with values left and right.

@alex-courtis What do you think about this idea? Does it work for you?

Also, we should decide when there is not enough room for the icons on the right. First, should we place icons on the right relative to the current window width or the max width? In both cases, what should be the behavior when there is no space to show all the icons on the right?

That might not be enough; renderer.icons doesn't have visibility or control over placement.

We'd need to create a new value for the ICON_PLACEMENT enum, say, right. We'd add that to Decorator and Builder:format_line could use it.

Current width might be best - some users like various types of dynamic widths and they wouldn't see the icons most of the time.

Interesting. We could follow the before behaviour and use renderer.icons.padding. Maybe we could try a single far right pad as well, something like:
