Where I rediscover an old piece of software

Some time ago I found iGal, a Perl program to produce galleries of photos.

Briefly after that, I decided to re-implement it. Mostly for fun and for exploring the challenges that this would pose. The result was pgal, which was available from my web site… at that time.

I guess these kind of softwares have been overseded by something different today. Or maybe not. Anyway, I found it useful again to build my previous post Some CC0 images, which gave me the prompt to…

  • … renovate the code a bit (e.g. by using Path::Tiny instead of a lot of other modules), and…
  • … package the software as a Docker image based on Alpine Linux.

So there you have it: pgal, the gallery generator!

To use the pre-packaged Docker image:

  • ensure you can get images from GitHub’s registry (this, I guess, requires you to have an account)
  • use the image!
docker run --rm -v "$ROOT:/mnt" "$PGAL" -c -r

This will get you started. At this point:

  • edit file/files .captions to provide a title to the album (or sub-albums too), as well as captions for each individual image (you can also reorder them and/or exclude some);
  • edit .index_template (in the album or in a sub-album) to change the appearance of the page indexing all photos;
  • edit .page_template (in the album or in a sub-album) to change the appearance of the page dedicated to a single photo;
  • re-run the command above to update the generated pages.

I guess this is it!
