[lsp-ui-sideline] Width calculation wrong when using left-margin-width' and right-margin-width'

[terlar]

If you set:

(setq left-margin-width 1
      right-margin-width 1)

It will calculate the width wrong and cause wrapping:

I don't have any problems with margins.
It seems that there is a new line or a tab in the message. Can you test if 8487eec fixes the issue ?

[terlar]

No this didn't change anything, it seems the left-margin-width doesn't affect after all. But I can easily reproduce by using (setq right-margin-width 1) and (setq right-margin-width 0). When I toggle between these two settings and refresh the line will wrap/not-wrap.

It might be related to some combination with some other setting, but the right-margin-width is definitely something that triggers it.

[terlar]

The theory was correct I also need to use:

(setq fringes-outside-margins t)

If i set this one to nil it won't wrap either. Might have even more settings that affects this, will try to check some more.

[sebastiencs]

Yes, I can reproduce.
b2fc92a should fix it

[terlar]

Yes, this fixes it, thank you for the quick resolution. I was looking through the code-base a bit and searching for some width calculation, but I am not so familiar with the code base yet.
