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.
