xmenu VS imlib2-jxl

It does not have a context menu. Instead, it uses a script set in the $XFILES_CONTEXTCMD environment variable. This script must call xmenu, pmenu, thingmenu, jgmenu, or any other mouse-controllable menu; and gets as argument the paths to selected files.

xmenu

Another not centric way, but simple and fast is xmenu, which allows to use simple scripting for each row (common for any WMs): * https://github.com/phillbush/xmenu

here you go this is exactly what you want. You could reimplement this in your build or follow the suckless philosophy and use this tool.

xmenu https://github.com/phillbush/xmenu and generate with xdg-xmenu https://github.com/OliverLew/xdg-xmenu, I like this style and configuration of it. It is not in lua, but idea and concept is suckless.

Haven't tried this one since dmenu works for me, but I think xmenu might have better support for it. It's not as suckless but honestly dealing with multiple languages sucks lol

Nice. I also wrote a popup menu utility that has the same input-to-output interface as dmenu. But mine is a little more bloated: it supports input from keyboard, nested menus, icons and label/command separation.

The only other requirement should be xmenu

Have a look into dmenu, rofi and xmenu. They are all good at different things. The first two are keyboard driven and support a basic application menu by default. Xmenu is more like a context menu. For the most part you create the menus yourself with scripts. You can pipe stuff into their stdin and get the selected entry via stdout. Here is an example of what I use for my dwm build.

Unrelated but I found https://github.com/alistair7/imlib2-jxl which allows for JPEG XL image format to be displayed in feh or sxiv.
