I figure I would share this one more time. The thing is so handy I put it on my desktop but the original is blinding white and 1.5:1 aspect ratio. This is a quick recolor and resize to 16:9. There is a 90px margin on top that is sized for the GNOME header so that the content remains visible. Sorry if this post seems redundant. For me, having this reminder to keep trying to use Emacs is just the motivation I need to open a file in Emacs instead of just using gedit quickly.

::: spoiler bonus tip! On Fedora 40, if you have darkmode set to the default in GNOME, GNU Emacs does not follow the darkmode styling directive for the menu bar. I spent forever trying to make this work in darkmode. If the app is launched using $ GTK_THEME=Adwaita:dark emacs it will start with the menu bar set to dark mode.

However there is a script that actually launches Emacs in /user/bin/emacs-desktop. If you open that file and modify it by adding export GTK_THEME=Adwaita:dark emacs just before the last line, it will launch with darkmode enabled. This is the entire contents of that file:

#!/usr/bin/sh

# The pure GTK build of emacs is not supported on X11, so try to avoid
# using if there is an alternative.

if [ "$XDG_SESSION_TYPE" = 'x11' ]; then
    case "$(readlink -f /usr/bin/emacs)" in
    */emacs-*.*-pgtk)
        if type emacs-gtk+x11 >/dev/null; then
            exec emacs-gtk+x11 "$@"
        elif type emacs-lucid >/dev/null; then
            exec emacs-lucid "$@"
        fi
        ;;
    esac
fi

export GTK_THEME=Adwaita:dark emacs
exec emacs "$@"

I'm not claiming it is the right way. It just worked when I tried it.

Sometimes I do write-ups of the monthly Austin Emacs meetup. Here is the write-up for August.

I am excited to finally announce the release of Forge version 0.4.0, consisting of 699 commits since the last release two years ago. It was actually released six days ago, at the same time as Magit and nine other packages, which all had to be released at the same time.

I felt clunky doing NVIM and could never remember hotkeys for once a week -ish in-situ functional learning. Like I jump in FreeCAD for a few days, come back, and I can't recall a hotkey combo I only used once.

I think I can use Emacs lisp for some actual project goals with AI and other microcontroller projects involving FORTH, that I've never been able to figure out, and code complexity management issues I've never overcome. I still want the menu bar and am really unsure if the evil key bindings are for me. I would probably find it useful if I knew the vim bindings in situations like OpenWRT with busybox only, but it was the extreme complexity of navigating nvim help and key bindings that I found so useless to learn in-situ. Help me navigate this please. I'm being indecisive in a bad way about how to make this pretty, and get it configured.

I've been theming emacs, trying to get it to look just right, but the lack of a per face line spacing is making it kind of difficult. I've tried to use :box as a hack to add invisible spacing, but that started to look weird when the region is highlighted. Does anyone know why there doesn't seem to be much interest or discussion on this topic? I'd love to be able to just add a top or bottom margin to headings like in css.

Emacs RFC 2646 email flowing

Heck it Emacs!

A few months ago I fixed a bug in RFC 2646 handling where the last paragraph wouldn't get reflowed unless I remembered to add a hard newline (that is, a newline with the 'hard text property) after it, at EOT. I needed to hit one extra RET at the end. All other paragraphs would be wrapped, not just the last one.

(I even bugged @[email protected] about it.)

But it still didn't always work and today I tried to get to the bottom of why, spending the entire day debugging it, finally realizing that... It's not even being called when there's only one paragraph in the email. I wasted so much time before realizing that! And then getting to the bottom of why that wasn't happening was the opposite of easy but it turnes out that Gnus by design doesn't call the fill-flowed-encode function when there aren't any hard newlines in the buffer. Which there aren't gonna be if it's a single-paragraph letter πŸ€¦πŸ»β€β™€οΈ

Use-hard-newlines is beyond useless since that's always buffer-local and the text-reflowing is being done in a temp buffer. Instead since 2010 we're supposed to set mml-enable-flowed to true. But don't worry, fans of the messages-are-flowing package, I'm gonna send patches there to reflect that. I have a bunch of other changes to that package too since I've been using that a lot this summer.

This is all in bug#71017 (cursed palindrome!) for people who wanna dig in πŸ‘©πŸ»β€πŸ«

Suggestions for a complimentary typeface to JetBrains Mono for reading and writing documents or prose

I am looking for a typeface that complements well to the one that I use to write code (JetBrains Mono). I will be using this to write documents and articles.

For further context, I am configuring Emacs' org-mode where I would be using both typefaces together. I could use JetBrains Mono for both purposes as I find it capable. But I would like to explore my options.

I have also looked at Iosevka. It offers variants for coding, reading, and writing. But I would prefer to stick with JetBrains Mono as much as I can for coding purposes.

Hello, friends!

So I have a complex way of capturing TODO tasks for today or week. Someone will probably tell me that there's a package out there somewhere to do this easier, but regardless I would like to figure this out.

Here's the function I use:

(defun org-capture::today-task-tree ()
  "Create a task tree for tasks TODO today."
  (let* ((time-string (format-time-string "<%Y-%m-%d %a>" (current-time)))
         (heading (concat "[%] " time-string))
         (heading-rx
          (rx (group "[" (0+ num) "%]") (0+ space)
              (group (literal time-string)))))
    (goto-char (point-max))
    (if-let (pnt (re-search-backward
                  heading-rx
                  nil t))
        (goto-char pnt)
      (goto-char (point-max))
      (or (bolp) (insert "\n"))
      (insert "* " heading "\n")
      (beginning-of-line 0))
    (org-end-of-subtree)))

And here's the org-capture-templates entry:

("gt" "Today: A task for today" entry
                     (file+function
                      ,(expand-file-name "~/Documents/Org/GTD/work.org")
                      org-capture::today-task-tree)
                     (file ,(concat my-emacs-dir "capture-templates/datetree-weekly-tasks.tmplt"))
                     :empty-lines-after 1
                     :after-finalize (lambda () (org-update-statistics-cookies t)))

And here's the actual capture template that I store in a file in my config:

** [ ] [#%^{Priority}] %^{Task name}  %(funcall-interactively #'org-deadline nil (current-time)) %^g
    %? %i

Now when I'm in that file ~/Documents/Org/GTD/work.org and I run the above function with M-: org-capture::today-task-tree it works fine. An example of what the file will look like it:

* [100%] 2024-04-27 Mon
** [X] Do something important this Monday #[A] :work:
    CLOSED: 2024-04-27 Mon 12:42  DEADLINE: 2024-04-27 Mon
* [%] 2024-04-28 Tues
** [ ] Do something else that's not as important #[B] :personal: 
     DEADLINE: 2024-04-27

But for whatever reason when I run org-capture and finish the capture with C-c C-c or refile with C-c C-w I get

rx--translate-bounded-repetition: rx β€˜**’ range error

Which I don't really know what that means nor how to fix it, and I can't really find anything useful via searching the internet at the moment. A possible thing to not is that I disable Org's element caching.

If you want to look at my configuration to dig around some, you can find it here and the part where my configurations for Org-Mode are here.

In my pursuit to migrate from Vim to Emacs, I have stumbled on yet another roadblock.

When working with files that contain special whitespace characters, Vim/Neovim would automatically highlight these. This saved me a lot of time during debugging or data analysis, and is a functionality that I struggled to get to work on more modern IDEs.

However, this does not work out-of-the-box neither on vanilla Emacs nor Doom Emacs. I am unable to find any working solutions online. I assumed whitespace-mode would have handled this, but it is not the case.

It would be really helpful if the community here can help solve my problem as I deal with such characters on a daily basis. Until then, I have to pause my pursuit and stick with the trusty Neovim.

U+200B in Neovim

Notice Neovim highlighting the character as <200B>.

U+200B in Doom Emacs

Notice the think cursor between "hello" and "world".


Thanks to the suggestion by @[email protected], glyphless-display-mode allows me to view the characters. But it still doesn't play well with vim motions on Emacs.

Here is a demonstration, and below are the keystrokes.

  1. C-v to enable VISUAL-BLOCK mode.
  2. 9j to select all 9 occurrences.
  3. d to delete the selection.

The above vim-motion works on Neovim but not on Emacs with evil-mode.

If anyone wants to try out here is the text I am playing with:

hello ​ world
hello ​ world
hello ​ world
hello ​ world
hello ​ world
hello ​ world
hello ​ world
hello ​ world
hello ​ world
hello ​ world

I've been using konsole (and iterm2 on my work mac) for most of my working career, but on the linux side, I've recently switched to Kitty, but now I'm wondering if I can finally get used to just using emacs on both.

Does anyone use emacs as their main terminal? Is there one better than ansi-term that supports modern features like libsixel?

I still can't quite get used to the keybindings (like C-c twice for ^C) and some other weirdness.

I wrote this script to learn how completing-read's complex arguments works. Compared to other clients it's quite limited; but thanks to packages like Vertico and Orderless, it works quite well for my use cases.
