This is not my work, but the author (same author as zsh-abbr) posted it elsewhere and it looks good to me.

In his words:

What is zsh-test-runner? A simple testing framework for zsh, and to a degree —thanks to zsh's emulation of other shells— csh, ksh, and sh.

The immediately noticeable difference between zsh-test-runner and other shell script unit test frameworks is it doesn't have a DSL. zsh-test-runner relies entirely on the shell's own testing. For those familiar with other frameworks: nothing like ShellSpec's Describe … When call … The output should, or shUnit2's assertEquals, or ZUnit's assert; zsh-test-runner is closer to Bats if you were to restrict yourself to core and not use helper libraries (there's nothing like bats-assert's assertEquals or bats-file's assert_dir_exists).

Why no special syntax? It means there's little new to learn— For example, if you know how to test numeric equality in your shell, you know how to test equality in zsh-test-runner; if you don't, there are community resources available. It means every possible test is supported equally out of the box— zsh-test-runner is a newcomer, but there are no "shoot my assertion method isn't supported" blockers. It means the cost of porting homegrow framework-less tests to zsh-test-runner is about as low as can be— generally speaking, my_cool_test_code becomes ztr test 'my_cool_test_code'. It means tests can live comfortably in one LOC, making zsh-test-runner pleasant to use in the terminal.

Hello!

I'm still using X11, and one of the things that's keeping me there is that I make heavy use of a launch-or-focus script, so that I hit a certain hotkey and no matter what a browser/chat/editor/terminal/file-manager/etc. shows up focused on my current desktop.

In the world of Wayland, this isn't so easy. If this can be recreated at all, I think it'll have to be made to rely on some sort of interface to Kwin.

I don't think it's possible now, but might it be in the future?

Here's my script, let's see if the lemmy interface mangles it (EDIT: yes, the last character should be an ampersand, not &):

#!/bin/zsh -ex

# -- Usage --
# ./toggle_window.zsh LAUNCH_CMD [ WM_CLASS [ CHECK_CMD ] ]

# -- Defaults --
# WM_CLASS and CHECK_CMD each default to the value of LAUNCH_CMD

# -- Examples --
# ./toggle_window.zsh dolphin
# ./toggle_window.zsh wezterm-gui org.wezfurlong.wezterm
# ./toggle_window.zsh firefox firefox firefox-bin
# ./toggle_window.zsh \
#   'flatpak run --branch=stable --arch=x86_64 --command=telegram-desktop --file-forwarding org.telegram.desktop' \
#   telegram-desktop telegram-deskto
# Yes, "telegram-deskto" without a final p. Hmm.

# -- Dependencies --
# - procps (pgrep)
# - wmctrl
# - x11-utils (xprop)
# - xdotool

# -- TODO --
# - wayland

launch_cmd=(${(z)1})
wm_class=${2:-$1}
check_cmd=${3:-$1}

if [[ $(xprop -id $(xdotool getactivewindow) WM_CLASS) =~ \"$wm_class\" ]] {
  xdotool getactivewindow windowminimize
} else {
  wmctrl -xR $wm_class || true
}

pgrep -u $USER -x $check_cmd || exec $launch_cmd &
