colorcolumn and foldtext

[Carlos Pita]

Hi all,

is there any way to force the color column to show above a fold header?

I tried:

highlight Folded cterm=none ctermbg=none

and

highlight clear Folded

to no avail.

See the attached screenshot in case I'm not being clear.

Cheers

Hi Carlos!

I don't think there is a possibility. Vims highlighting priorities are
mostly hard coded in the source. So there is nothing you can do about.

Here is a patch, that makes the colorcolumn drawn on top of folded
regions.

The idea of 'colorcolumn' is that it applies to the text. So you can
align items or make sure they are in a certain column. I don't see
how that is useful in a folded region. I would think it makes the
closed fold look odd. I have the idea that the closed fold is "above"
the text and the 'colorcolumn' is "under" the text.

So, why would someone want to change this?

I see the rationale behind what you're saying and I do agree. But there is a
gotcha. It's related to the way the fold line is filled with chars (as in
'fillchars'). Say I find it too invasive so I set the fold fillchar to space
and its background to the normal background, in order to turn it "invisible".
Now I have a colorcolumn splitted here and there and that *really* looks odd.
Maybe the solution is not to force filling the fold line all the way to the
right margin but to make it the length of the string foldtext() returned.

Something like an "empty fillchar" (which is currently impossible
AFAIK) would do the trick while still allowing for the current
behaviour in a backward compatible way, albeit I don't know if a
generalization like that is desirable and/or easy to implement.

I would see it the other way around. But that is debatable, I guess. I
just thought, when the cursorcolumn is displayed, the colorcolumn might
as well be displayed.

Because broken colorcolumns looks ugly ;)

I have to admit that it's now inconsistent, having cursorcolumn and
colorcolumn behave differently. Did anybody complain about the behavior
of cursorcolumn? Perhaps then it's best to do the same for colorcolumn.
Consistency is more important in this case.

Not that I know of. Carlos as the original Poster did ask how to make it
the colorcolumn work with folded regions and it looks like he has asked
the same question on Stackoverflow:
http://stackoverflow.com/questions/28892305

I wouldn't call it a complain however.

Hi again,

an update: it's a bit worst than I've described, as the number columns
at the left also look splitted. See the attached screenshot.

I'm not sure whether this is an argument pro or con fold header being
above whatever special column. At least the idea of the fold header
being above every special column is already implemented and has it's
rationale, as Bram exposed it. Of course, it looks bad when one tries
to make it "transparent", as the visual effect is to make every
special column look splitted instead of just at a lower layer. Maybe
the solution is to refrain from trying to style the fold headers in a
more modest fashion and always give them a distinctive "here I am"
background. I don't know.

Cheers

Do you mean, that the number setting isn't updated? How did you do this?
Does a manual redraw using :redraw or :redraw! help?
I can't seem to replicate that behaviour.
