So to avoid breaking TTY display of Emacs 30 and older, we should replace 💡 and ⚡ with narrow (one-column) characters for this emoji? Or at least say in the doc string that users of Emacs 30 and older should not select these double-width characters on TTY frames? If not, what would you suggest as a solution for Emacs 30 and older, where wide characters displayed in one-column margin might cause display problems on TTY frames?

"Probably Flymake" is the answer.
If you happen to launch Eglot without Flymake (very unlikely but possible),=
then
noone does. Eglot doesn't set it up and you'll miss one of the many
possibilities
that indicates a code action at point. But in the overwhelming
majority of cases,
Flymake, which is auto-started by Eglot unless you explicitly forbit
it, sets up
the left margin to display its own stuff, and Eglot goes along for the ride=
.

Because it was unforeseen complexity, and there isn't any way, let alone
a good way, to negotiate margins with other packages, so Eglot uses the
margin on a "hope for the best" basis. It works ok, except for this
double-width problem. I know some terminals handle this well. If the next=
cell
is a blank, they overdraw, else they truncate. MinTTY at least does this.
But I agree it shouldn't be a double width char.
> Am I missing something here?
I know I am. I could have sworn this bit of code:
(save-excursion
(goto-char (car bounds))
(let ((ov (make-overlay (car bounds) (cadr bounds))))
(overlay-put ov 'eglot--actions actions)
(overlay-put ov 'eglot--overlay t)
(overlay-put
ov
'before-string
(cond ((memq 'nearby eglot-code-action-indications)
tooltip)
((memq 'margin eglot-code-action-indications)
(propertize "=E2=9A=A1"
'display
`((margin left-margin)
,tooltip)))))
(setq eglot--suggestion-overlay ov)))
used 'eglot-code-action-indicator', but it clearly doesn't.
I'll investigate this bit later. Anyway I hope your question about
"who sets margins"
was answered.

So it is indeed two packages. I guess I'm missing something. Would you please explain which package sets up the 1-column margin in this scenario? If it isn't Eglot, why doesn't Eglot do it, if it wants to display some indicator in the margin? These margins don't appear automagically, they must be set up to show something in them, so Eglot cannot just use a 'display' property that displays in the margin without setting up those margins. So why doesn't it? Am I missing something here?

No, neither of those approaches would work, because flymake indicators are not displayed for lines with eglot code actions. Eglot is not using the lightbulb as a flymake indicator. It's using it as an indicator for eglot code actions on the current line, which has nothing to do with flymake. >> In bug#77313, we extensively discussed how to properly automatically >> update window margins when there are multiple packages using the >> margins, and Juri posted a patch to emacs-devel to add a >> window-margin-functions hook.

And, of course, even if those changes are landed soon, they will not help people who use older versions of Emacs. Thus, I still think we should try to fix Eglot or Flymake to set the window-margin width in this case, because that would at least avoid the display problem with older Emacsen.

If Eglot wants to use the lightbulb character as indicator, can't it override the default value of the flymake indicator to make Flymake aware of the wider string? Alternatively, perhaps Flymake should provide a hook for callers to customize the indicator string and/or the required width of the window margins? > In bug#77313, we extensively discussed how to properly automatically > update window margins when there are multiple packages using the > margins, and Juri posted a patch to emacs-devel to add a > window-margin-functions hook.

That's not directly related, since in this case AFAIU only one package wants to display on the margin, right?

To be clear, Eglot's use of =F0=9F=92=A1 in the margin for code actions is = totally unrelated to flymake, and there's not currently a way to make flymake aware of it. It just happens to be the case that enabling flymake resizes the margin to width=3D1 as a side-effect. It's totally unintentional, not deliberate. In bug#77313, we extensively discussed how to properly automatically update window margins when there are multiple packages using the margins, and Juri posted a patch to emacs-devel to add a window-margin-functions hook. But it never actually landed - I think there was some disagreement on emacs-devel which I didn't follow.

So an easier solution is to fix flymake-mode, which needs to be done anyway, even with the display bug fixed. It looks like flymake-mode determines the margin width without knowing that Eglot uses 💡 as the indicator, am I reading the code correctly?

Oh, this is it. I'm running Emacs 30 with an updated Eglot from ELPA. On Emacs 30 I see the lightbulb after my recipe, on trunk I don't. I guess this is still a bug, though, because Eglot is supposed to work on old Emacs versions. (I guess I won't bother trying to backport the trunk fix to my site's Emacs 30 branch... there are probably lots of changes that could affect this) > Also, can you tell me where does Eglot determine the width of the > margin and sets that up? One column is definitely wrong when the > character is wider. I don't think eglot ever actually resizes the margin. But flymake-mode does resize the margin, and eglot (by default) turns on flymake-mode. And you're right, this causes the margin to be the wrong size.

The lightbulb shows up in the left margin, even though the margin is not large enough for it. At this point, I see a margin of 1 column, but the lightbulb character doesn't appear on display. If I now enlarge the margin to 2 columns, the character is shown as expected. This is in PuTTY logged into a GNU/Linux system identified as $ uname -a Linux <redacted> 5.15.0-168-generic #178+11.0trisquel31 SMP Fri Jan 30 00:12:08 UTC 2026 x86_64 x86_64 x86_64 GNU/Linux and running today's master branch. > 4. split-window-right; the separator between the two windows is > misaligned on the line with the lightbulb. No problem with display after this step, neither with 1-column margin, nor with 2-column margin. And if I leave one of the two split windows with 1-column margin and give the other one 2 columns, the character is correctly displayed only where there are 2 columns. So I wonder what is different in your case. How wide is the actual lightbulb character on display in your case? Here it is as wide as two 'x' characters. Also, can you tell me where does Eglot determine the width of the margin and sets that up? One column is definitely wrong when the character is wider.

Open up a large file (e.g. eglot.el) 2. (progn (overlay-put (make-overlay 8000 8001) 'before-string (propertize " " 'dis= play '((margin left-margin) "=F0=9F=92=A1"))) (set-window-margins (selected-window) 1 0)) 3. The lightbulb shows up in the left margin, even though the margin is not= large enough for it. 4. split-window-right; the separator between the two windows is misaligned on the line with the lightbulb. I can't reliably reproduce the other glitches I was seeing; I suspect the fact that eglot removes and re-adds the margin lightbulb as you scroll is contributing. But this seems like evidence enough of a bug. (char-width ?=F0=9F=92=A1) is 2 for me as well.

But whenever that emoji is displayed in the left margin (a= s it is by default since eglot-code-action-indications contains 'margin by default), Emacs display breaks: e.g. by duplicating the line with the lightbulb on it or not updating it as you type. Maybe this is related to how "=F0=9F=92=A1" is displayed as a double-width character? Maybe Emacs thinks it's displayed as a single-width character?
