gallery
=======

This is gallery software designed to maintain a shadow structure
of your filesystem, in which you can attach metadata to your media,
and query your collections in various ways.

All media is content-addressed by its SHA-1 hash value, and at your option
also perceptually hashed.  Duplicate search is an essential feature.

The gallery is designed for simplicity, and easy interoperability.
sqlite3, curl, jq, and the filesystem will take you a long way.

Prerequisites: Go, ImageMagick, xdg-utils

ImageMagick v7 is preferred, it doesn't shoot out of memory as often.

Getting it to work
------------------
 # apt install build-essential git golang imagemagick xdg-utils
 $ git clone https://git.janouch.name/p/gallery.git
 $ cd gallery
 $ make
 $ ./gallery init G
 $ ./gallery sync G ~/Pictures
 $ ./gallery thumbnail G             # parallelized, with memory limits
 $ ./gallery -threads 1 thumbnail G  # one thread only gets more memory
 $ ./gallery dhash G
 $ ./gallery web G :8080

The intended mode of use is running daily automated sync/thumbnail/dhash/tag
batches in a cron job, or from a systemd timer.

The _web_ command needs to see the _public_ directory,
and is friendly to reverse proxying.
