Ok so this is not satisfactory. Or maybe, after having increased the margin, we should always put the overlay arrow starting at first column. This is not really different than what we have now in the text area. -- Manuel Giraud

Indeed, I meant 'overlay-arrow-position'. But maybe changing
the length of 'overlay-arrow-string' also should reserve
the corresponding number of columns in the margins area.

By design, 'window-margin-functions' is a list of functions,
so its default value could be something like this:
(defvar window-margin-functions '(window-margin-overlay-arrow))
(defun window-margin-overlay-arrow ()
"Return the number of margin columns."
(when overlay-arrow-position
(length overlay-arrow-string)))

We could do this, if we don't care about other features that use the margins. Do we envision that there will be some situations where the user or some Lisp program will prefer not to use the margin even though it is available?

[You mean, overlay-arrow-position, I presume (overlay-arrow-string is always defined)?] Yes, that will work, but since these variables are modified from Lisp, it would mean that setting up the margin will be the responsibility of the calling Lisp program. Whereas I thought you wanted to have some feature whereby the margin will be shown automatically when the overlay-arrow is activated?

What do you think of this new patch? While working on it, I thought
that I could use the presence of a left margin to decide what to do.
This way the interface for users of overlay arrow is "have a margin if
you want to use it" and this falls back to overlay into the text area
otherwise.
FWIW, I have tested this on a Gnus summary buffer and with olivetti-mode
(a mode that uses left and right margin to center the buffer contents in
a window). When olivetti-mode is active the overlay arrow uses the left
margin and when I toggle olivetti-mode off, the overlay arrow
automatically switch to using the text area.

Unless I'm missing something, the code in the display engine is independent of Juri's patch, so it could be installed without waiting, with the caveat that any Lisp programs that want to use this will have to set up the margin "by hand" for the time being.

No, that's definitely not possible, because the basic geometry of the iterator is determined before display_line is called. So the only way to do that would be to abort the current redisplay, in a way that causes adjust_frame_glyphs to be called (e.g., by setting the frame's fonts_changed flag), and then repeat the display from the beginning.

Yes why not. Do you think it is possible to modify the window margin inside display_line?

Yes, but I think Manuel is looking for a solution that would "magically" create the margins as soon as the overlay-arrow-position is set non-nil. I don't think this is easy to accomplish, because the margins must be set before redisplay kicks in.

So users of overlay arrow just have to record the size of the arrow here? This is fine by me and more versatile than what I proposed. FTR, there is not just Edebug and "M-x gdb".

I don't know if it worth it to add more logical maze to xdisp.c for such a niche feature.

User option or not, we'll have to pinpoint every Emacs' code that uses overlay arrow and modify it to set up the window margins. But my question of acceptability was more about potential external/package code. -- Manuel Giraud

Hi Eli and Juri (and all),
I think I have found the issue of why the overlay string does not
appeared in the margin: the glyph row's used[LEFT_MARGIN_AREA] was not
moved accordingly.
This new patch makes this feature works with Edebug but now I have one
question. With this feature, every user of overlay string have to
activate the window margin (as I have done with Edebug) otherwise the
arrow won't be visible at all (I have tested it in Gnus). Is it
something acceptable?

Do you need help debugging this? Or did you expect me to debug it?
If the former, I suggest first to look at the glyph row near the end
of display_line (e.g., using the 'pgrow' GDB command defined in
src/.gdbinit) and see if the glyphs of the arrow are in the glyph row.

Maybe I'm missing something and/or oversimplifying, but it sounds like
"all you need" is to modify the code in display_line which starts with
this:
/* If the start of this line is the overlay arrow-position, then
mark this glyph row as the one containing the overlay arrow.
This is clearly a mess with variable size fonts. It would be
better to let it be displayed like cursors under X. */
if ((MATRIX_ROW_DISPLAYS_TEXT_P (row) || !overlay_arrow_seen)
&& (overlay_arrow_string = overlay_arrow_at_row (it, row),
!NILP (overlay_arrow_string)))
{
/* Overlay arrow in window redisplay is a fringe bitmap. */
if (STRINGP (overlay_arrow_string))
{
to put the glyphs it produces for the overlay-arrow in the margin
instead of text-area of the glyph row. Of course, this should be
conditioned on the margin being wide enough (so users will need to
set-window-margins to actually have the arrow displayed. You will see
that the code I mention puts the glyphs of the arrow in the TEXT_AREA
part of the glyph row. You want to put then in the LEFT_MARGIN_AREA
instead.
IOW, the arrow glyphs will "magically" appear in the margin at the
correct screen line, like they now "magically" appear overwriting the
displayed buffer text, without any 'display' property or overlay
specifying that they should appear.
One complication is that the above code is after the left-margin
glyphs were already produced by this function. That might mean this
code will need to be moved back towards the beginning of display_line,
so that the overlay-arrow glyphs take precedence.

Yes, but those columns are usurped in advance when there are no fringes, so they unconditionally remove 1 column from the width of the window. I don't think it'd be the best idea for the overlay-arrow, especially given that the default arrow string takes 2 character cells.

Could it be extended to support more margin columns? Or maybe by "display element" you mean glyphs that come from the display-table? If so, the special glyphs do come from a display-table, but I don't see what that has to do with the margin. A display-table is a way of displaying a character as another character or a string of characters, regardless of where the original character was supposed to be shown on display.

Not sure I understand what you mean by that. overlay-arrow-string is exposed to Lisp, so Emacs must obey its value and cannot change it, if that's what you meant. And even if we'd want to change the string, it won't help. By default, overlay-arrow-string is a 2-character string, but can be longer. So for any source line that has anything but SPC characters in the first 2 columns, we must overwrite some contents of the line to show the arrow. In the case of a leading TAB, we could perhaps make the stretch glyph used to show the TAB narrower by recomputing its pixel-width, but that is a solution only for some of the use cases. More generally, the UI of the GUI frames is _with_ the fringes. We added the no-fringes option because someone asked for it for reasons I couldn't understand even back then. But I wouldn't want us to go out of our way to make this niche feature work as well as the default UI with the fringes, especially when the problems are not easy to solve. After all, all that a user who debugs code needs to do to avoid overwriting the first characters on a line is to enable fringes, if only for the duration of the debugging session.

Hi,
When using 'no-fringes mode (or on TUI), edebug relies on
`overlay-arrow-string' and `overlay-arrow-position' to mark which line
it currently is in the code. This is nice but when a line in the code
is indented with TAB characters, this overlay mechanism "moves" the line
at an incorrect indentation place.
Here is a recipe to reproduce this with the attached file:
- emacs -Q
- M-: (set-fringe-mode 0) <RET>
- Open the attached file "edebug-overlay-test.el" and instrument
the function +foo with 'C-u C-M-x'
- M-x +foo <RET>
- Step in the code by hitting <SPC> repeatedly and observe that
stepping on line 6 the line is "moved" to a different column
resulting in a temporary incorrect indentation

(let ((world "World!"))
(let ((unused "Foo"))
(message hello)
(message world)))))
