I was drafting support for showing “application icons” in my window manager, i.e. the Firefox icon in the titlebar:

Then I realized: Wait a minute, lots of applications don’t set an icon? And lots of other window managers don’t show these icons, either? Openbox, pekwm, Xfce, fvwm, no icons.

Looks like macOS doesn’t show them, either?!

Has this grown out of fashion? Is this purely a Windows / OS/2 thing?

(#euobsca) @lyse@lyse.isobeef.org @kat@yarn.girlonthemoon.xyz I spent so much time in the past figuring out if something is a dict or a list in YAML, for example.

What are the types in this example?

items:
- part_no:   A4786
  descrip:   Water Bucket (Filled)
  price:     1.47
  quantity:  4
- part_no:   E1628
  descrip:   High Heeled "Ruby" Slippers
  size:      8
  price:     133.7
  quantity:  1

items is a dict containing … a list of two other dicts? Right?

It is quite hard for me to grasp the structure of YAML docs. 😢

The big advantage of YAML (and JSON and TOML) is that it’s much easier to write code for those formats, than it is with XML. json.loads() and you’re done.

(#6u6yutq) @lyse@lyse.isobeef.org I might need that script as well. 🙈🙏

Only figured this out yesterday:

pinentry, which is used to safely enter a password on Linux, has several frontends. There’s a GTK one, a Qt one, even an ncurses one, and so on.

GnuPG also uses pinentry. And you can configure your frontend of choice here in gpg-agent.conf.

But what happens when you don’t configure it? What’s the default?

Turns out, pinentry is a shellscript wrapper and it’s not even that long. Here it is in full:

#!/bin/bash

# Run user-defined and site-defined pre-exec hooks.
[[ -r "${XDG_CONFIG_HOME:-$HOME/.config}"/pinentry/preexec ]] && \
        . "${XDG_CONFIG_HOME:-$HOME/.config}"/pinentry/preexec
[[ -r /etc/pinentry/preexec ]] && . /etc/pinentry/preexec

# Guess preferred backend based on environment.
backends=(curses tty)
if [[ -n "$DISPLAY" || -n "$WAYLAND_DISPLAY" ]]; then
        case "$XDG_CURRENT_DESKTOP" in
        KDE|LXQT|LXQt)
                backends=(qt qt5 gnome3 gtk curses tty)
                ;;
        *)
                backends=(gnome3 gtk qt qt5 curses tty)
                ;;
        esac
fi

for backend in "${backends[@]}"
do
        lddout=$(ldd "/usr/bin/pinentry-$backend" 2>/dev/null) || continue
        [[ "$lddout" == *'not found'* ]] && continue
        exec "/usr/bin/pinentry-$backend" "$@"
done

exit 1

Preexec, okay, then some auto-detection to use a toolkit matching your desktop environment …

… and then it invokes ldd? To find out if all the required libraries are installed for the auto-detected frontend?

Oof. I was sitting here wondering why it would use pinentry-gtk on one machine and pinentry-gnome3 on another, when both machines had the exact same configs. Yeah, but different libraries were installed. One machine was missing gcr, which is needed for pinentry-gnome3, so that machine (and that one alone) spawned pinentry-gtk …

(#snvjaoa) @lyse@lyse.isobeef.org The cynic in me says: “It’s not bleeding edge, it’s from 2008!” That’s not fair, though, looks like the issue only arose in libinput in 2019. And maybe these weird mice are super rare. Dunno.

(#nrqg3fq) @lyse@lyse.isobeef.org The underlines are a bit much, yes. It appears to be related to my font (Helvetica) … Maybe they do some Unicode trickery these days, I don’t know. 🫤
