TTY Vertical divider face?

TTY Vertical divider face?

[Len Trigg]

Hi all,

How can I set the face used to display the vertical divider that
separates side-by-side windows (I am running in a TTY).  I was
initially told that modeline-inactive face would do the trick, but I
think my question was misunderstood.  It would seems a strange
omission if such a thing were not possible.

I have tried compiling emacs myself (actually the current multi-tty
branch), and I can see in dispnew.c where the '|' character is used
for the vertical divider, but do not understand how to associate a
face with that.  Any ideas?


Cheers,
Len.

I had tried googling for answers to this before I posted, but lacked
the right keywords.  Kim Storm gave me some clues and I found that the
following code works:

(set-display-table-slot standard-display-table
			'vertical-border
			(let* ((face 'mode-line)
			       (face-offset (lsh (face-id face) 19)))
			  (+ face-offset ?|)))

(FYI, I actually found the information in a fairly old bug report
where they were using isearch rather than mode-line face and it
segfaulted emacs -- and in that case it still does).  I'm posting my
reply here so that hopefully it'll be easier for people to find in
searches in the future.

I'd like to also suggest that this be made a default, perhaps using a
specific vertical-border-face, to be more consistent with how the rest
of face customization works.

Cheers,
Len.

Using inverse colors for the vertical border on a TTY (where the
border is displayed as a dash line) seems like a natural default.
Is it possible to set inverse colors for the vertical border
by default without using the display table?

It's easy just using the same method Len used in lisp.  Any objection
to the following patch?  Should it use a different face (note that the
actual face that ends up being used by this code is
`mode-line-inactive', even though the code says MODE_LINE_FACE_ID; I'm
not sure why this is)?

I think yes.  I'd personally set its both background and foreground
colors to "white" to display the vertical border as a solid
1-character-wide white line.

I tried your patch, but instead of either `mode-line' or
`mode-line-inactive' it displays the vertical border in the
`fringe' face.  But maybe this is good.  We can reuse `fringe'
face for the vertical border because fringes are not available
on text-only terminals.

Hmmm, it's an interesting idea in that it displays a "dashless" block
by default, but still does the right thing if the terminal doesn't
handle reverse-video for some reason (this used to be an issue in the
'80s anyway :-).

However I think doing that makes it harder to follow the user's
customizations, since such a face couldn't just inherit from
`mode-line' (it could inherit, but then would have to set the
foreground to something explicit, which would often be wrong for
customized mode-line faces).

A slightly more complex alternative would be to do a "face
displayable" test on the "vertical divider" face, and if it's
displayable, use a space instead of "|" as the character...  Then just
inheriting directly from mode-line would work usually.

It sounds like it's randomly choosing some other face than what was
requested, which I think is not good even if it often works out...:-) 
I'll try to see what's going on...

    to the following patch?  Should it use a different face (note that the
    actual face that ends up being used by this code is
    `mode-line-inactive', even though the code says MODE_LINE_FACE_ID; I'm
    not sure why this is)?

Defaulting to mode-line-inactive seems better than defaulting
mode-line, but if it is implemented this way, there should be a
comment to explain that this code doesn't do what you might have
expected it to do.

However, on principle it seems wrong to use mode-line-inactive
directly.  There ought to be a separate named face to control this.
It could default to mode-line-inactive.

Re: TTY Vertical divider face?

[Juri Linkov]

There is something wrong with handling faces in display tables on
character terminals.  Putting a character with an added face to the
display table slot results in a different face displayed.
Some faces even cause Emacs to crash.  For example, Emacs started
with `emacs -Q -nw' crashes on GNU/Linux with the following code:

(progn
  (setq standard-display-table (make-display-table))
  (set-display-table-slot standard-display-table 'vertical-border
                          (+ (lsh (face-id 'isearch) 19) ? ))
  (split-window-horizontally))

I'll do this.

What should the face be called?  `divider'?  `window-divider'? 
`vertical-divider'?

The name used for the display table slot is `vertical-divider' so I'll
use that for the face too.

FWIW, the display table slot is called `vertical-border'.

Ack, you're right!  I guess I'll go change the face name to match...

Hmmm on the other hand, there's already a face `border', with a
different meaning (for setting the X border pixel color).

The name `vertical-border' seems slightly strange too -- the word
"border" seems to typically imply an "outer" border, dividing inside
from outside; calling the line between windows a border sounds
slightly strange to me (though it's technically correct I guess).

Maybe it would be better to keep the face-name as `vertical-divider',
and also change the name of the display-table slot to match (it's easy
to provide a backward-compatibility alias for that).

What do other people think?

I don't like "divider" much.

Is it possible to reuse the same face for vertical divider with an
additional spec like '(((type tty) :inherit mode-line-inactive))?

A vertical divider between two windows is the right border for the
left window, and the left border for the right window.

That sounds pretty forced.  Ideally I'd like to rename the current
`border' face to something like `frame-border' (which is more
accurate), but I don't know if it's worth the trouble.

Technically that may be true, but I don't think most users perceive it
that way -- the vertical dividers only ever show up between pairs of
windows, and are not linked to either one; they really do act like
"dividers".  Contrast this with mode/header-lines, which show up with
single windows, and are clearly connected with their window.

However, I don't really care very much and Richard likes
vertical-border better, so I'll use that.

It makes sense to use the new `vertical-border' face not only
for defining a vertical divider on character terminals, but also
on X for defining the foreground color of the vertical thin line
between windows.  Currently its color is the same as the default
foreground color, but users might expect that the same face defines
the color of the vertical separator line on X too.

    for defining a vertical divider on character terminals, but also
    on X for defining the foreground color of the vertical thin line

That seems natural.

Is that line present even when there is a scroll bar?

I want also to fix the problem where the vertical border steals
1 pixel from the text area of the right window.  This makes some
letters indistinguishable.  The patch below draws the vertical border
1 pixel left when there are no scroll bars and no left fringes.
These screenshots demonstrate how the vertical border looks
before and after applying the patch:

I think we need to address this problem, and your change may work --
but what happens if the window on the left has a scroll bar on the
right?

I have been considering the following approach:

- if there are no scroll-bars, your approach is good.

- if window has a scroll-bar on the left, reduce width of
  scroll-bar by one pixel, and put line on the left side of
  the scroll-bar.

- if window has scroll-bar on the right, and the window
  on the left of this window also has scroll-bar on right,
  reduce width of other window's scroll-bar and put line
  on right side of that scroll-bar.

- if window has scroll-bar on right, and window on
  the left has scroll-bar on left, don't show the
  vertical line (the dual scroll-bars next to each other
  is enough to show which window the scroll-bars belong to).


Actually, in most cases, the scroll-bars are already a little
narrower than a full multiple of the column width, so there may
already be room for the vertical line without reducing the
scroll-bar width.


So although your change may give good results in most cases,
I think there are cases where it may fail (if you happen to
move the vertical line into an area occupied by a scroll bar...

Currently there is no vertical border when there are no scroll bars
on either side of the window.  My fix was intended only for this case
(no scroll bars and no fringes).  As I understand, you propose to
display the vertical border even with scroll bars.  Perhaps this
requires considerable changes in the display code, so if you will
implement that (after the release?), then of course you have to
reconsider the case that displays the vertical border one
pixel left.

Yes, but the current behaviour works alright, so there is no need to
pursue this any further.

I agree with this change, but meanwhile, this is another instance of
why we need to be able to have frames and windows whose widths are not
even multiples of the default character box.

When the foreground is unspecified, then it uses the default
foreground, which is ok.

I'm sorry I forgot to post another part of changes in faces.el.
The `vertical-border' face should inherit from `mode-line-inactive'
only on tty.  It has an inappropriate foreground color for the
vertical border on X.  Without any specification, on X it will
use the default foreground color:

    What about such a patch?  I have tested it on GNU/Linux, but the
    change in w32term.c is untested.  I hope someone will test it
    on Windows.

Please install the non-Windows part of the patch.  Those who support
Emacs on Windows can decide what to do with the other part.  (Someone
who's interested in Mac's might want to patch the mac files for this.)

FWIW, the patch looks okay on Windows.  I customized vertical-border to make a pink window border.  (I don't know why, but more importantly, I can.)

Thanks for testing.  I installed that patch.

Re: TTY Vertical divider face?

    Maybe it would be better to keep the face-name as `vertical-divider',
    and also change the name of the display-table slot to match (it's easy
    to provide a backward-compatibility alias for that).

    What do other people think?

I like "border" better than "divider".

Fair enough.

    The name used for the display table slot is `vertical-divider' so I'll
    use that for the face too.

Using the same name is wise, but indeed it is `vertical-border'.
