A weird problem with elpa.gnu.org and mastodon.el in c/emacs

[–] nonreligious@alien.top 1 points 9 months ago (1 children)

What config do you have for mastodon.el in your init.el file?

Do you get any warnings or errors when starting Emacs?

How to apply different font for math fragments in org mode? in c/emacs

[–] nonreligious@alien.top 1 points 10 months ago

If you have the name of the font you want to use in the LaTeX fragments, have you tried using a LaTeX header at the top of the file, e.g.

#+LaTeX_HEADER:\usepackage{mlmodern}

(Replace mlmodern with whatever typeface you prefer)

If you don't want your .org file to become too cluttered at the start, you could alternatively use a setup file via #+SETUPFILE: /path/to/setup-file.org -- create an org file e.g. setup-file.org, and include a line like

#+LaTeX_HEADER:\usepackage{mlmodern}

or whatever your fixed-pitch/monospace font is supposed to be, as well as all the other options you want to use for LaTeX (like other \usepackage declarations, \newcommand definitions etc.).

`xwidget-webkit` has started crashing Emacs sessions in c/emacs

I see. What's the latest version of webkit that doesn't have this problem? Have you been able to downgrade to it to verify?

xwidget-webkit has started crashing Emacs sessions (alien.top)

submitted 11 months ago by nonreligious@alien.top to c/emacs

6 comments fedilink

I built Emacs 29.1 from source a few months ago and it was working pretty smoothly as far as I could tell -- I was mainly using the elfeed-webkit package -- until I tried to use it today and my Emacs session crashed. I was mainly using it in daemon mode, but evem just running emacs -Q and then M-x xwidget-webkit-browse-url RET wikipedia.org results in the error at the end of this post (sorry for the wall of text).

From the EmacsWiki and from reading /etc/PROBLEMS, I tried to use xwidgets-webkit again with SNAP=1 SNAP_NAME=1 SNAP_REVISION=1 emacs -Q, but it results in the same error.

It's probably an issue with my system rather than Emacs -- I'm running this on Manjaro Linux, and emacs-version gives:

GNU Emacs 29.1 (build 2, x86_64-pc-linux-gnu, GTK+ Version 3.24.38, cairo version 1.17.8) of 2023-08-28

What can I do to fix this?

(Below follows the error message referred to previously:)

Overriding existing handler for signal 10. Set JSC_SIGNAL_FOR_GC if you want WebKit to use a different signal
X protocol error: GLXBadWindow on protocol request 152
Serial no: 9165

When compiled with GTK, Emacs cannot recover from X disconnects.
This is a GTK bug: https://gitlab.gnome.org/GNOME/gtk/issues/221

straight-freeze-version gives straight--dir: Wrong type argument: (alien.top)

submitted 11 months ago by nonreligious@alien.top to c/emacs

1 comments fedilink

I'm trying to make my Emacs configuration more reproducible, in part by creating variables with paths to packages, directories which depend on what machine I'm on:

(if my/laptop-p
    (progn
      ...
      (defvar my/mu4e-dir            "/usr/share/emacs/site-lisp/mu4e"
  "Location of local `mu4e' files installed by system package manager")
      ...
                ))

Here, my/laptop-p tests if (equal (system-name) "my-thinkpad").

This system works well, so that for the relevant example of mu4e (which is apparently quite tricky to set up in straight.el ) I can use:

(use-package mu4e
  :straight
  (:local-repo my/mu4e-dir
               :type built-in)
               ...
               )

The package loads and the configuration works fine.

But doing straight-freeze-versions gives:

straight--dir: Wrong type argument: stringp, my/mu4e-dir

This can be fixed by replacing my/mu4e-dir with the string "/usr/share/emacs/site-lisp/mu4e", but I'd like to avoid this if I can.

Is there a way I can keep using my defined variable my/mu4e-dir instead of the full path name?

sage-shell-mode hangs when trying to run help(foo) (alien.top)

submitted 11 months ago by nonreligious@alien.top to c/emacs

0 comments fedilink

Does anyone else have the same problem?

If I run sage-shell:run-sage to get a SageMath shell in Emacs, and run help(), I get the standard help message, which starts with "Welcome to Sage 10.1!".

But if I try help(diff) or any other specific function, Emacs hangs. Doing C-g allows me to use Emacs again, but the SageMath session is no longer responsive: trying to enter any other command results in hanging. Even C-c C-d no longer works, I have to try C-c C-\ and wait for the SageMath kernel to crash, or do M-x kill-process.

This all seemed to work before I upgraded Emacs and changed my package manager to straight.el.

I'm on Emacs 29.1, using sage-shell-mode v0.3.

I've covnfigured it as follows:

(use-package sage-shell-mode
  :straight t
  :defer t

  :custom
  (sage-shell:sage-executable (executable-find "sage"))
  (sage-shell:set-ipython-version-on-startup nil)
  (sage-shell:check-ipython-version-on-startup nil)
  (sage-shell:use-prompt-toolkit nil)
  (sage-shell:use-simple-prompt nil)

  )

(However, I find that the custom settings aren't being respected either ...)

I also use ob-sagemath, which allows me to use SageMath in org-src-blocks, which works fine as far as I can tell.
