A script to generate Chafa galleries for gmi

Hey! I can only take credit for the idea, but I am sharing a little script cobbled together with artificial help that generates a little .gmi ANSI gallery out of images in a directory.

An example:

$ ls

something.jpeg

something_else.jpeg

testing.jpeg

another.jpeg

somefile.jpeg

$ ./chafa-gmi-gallery-gen.sh

Enter gallery name or leave blank to use the current date ('2024-04-20'): test

Enter image file extension(s) to look for or leave blank for all images (e.g., 'JPG' or 'png, jpg, gif, jpeg'): jpeg

Processing...

$ cd test

$ ls

index.gmi test-1.gmi test-2.gmi test-3.gmi test-4.gmi test-5.gmi

=> You need chafa installed.

Some more notes:

• If no gallery name is provided, it defaults to current date for gallery title and retains original file names.
• You can supply several image file types, comma separated.
• Feel free to change the chafa settings in the script. Currently it is set to output 240 colours, dithered, foreground only (for better compatbility), at a size of a 128 characters (felt the right mix). See the chafa man page for additional settings.

And let me know what you think.

What is a chafa?

It's in the links, but Chafa is a command line tool to convert images to ANSI / ASCII art for displaying in the terminal. Pretty neat. Many Gemini clients like Offpunk rely on it.
