This needs to be rewritten in python, and to handle files without exif data. +See python project "generate" (FIXME) for the improved version. + +### Static site generator +The [sigal](https://sigal.saimon.org/) site generator is installed with pip3, under local service account `sigal` on server1. A special script, `/usr/local/bin/sigal.bin` will generate the static pages for a site. TO use this script, pass a parameter of the source directory where the sigal.conf.py exists. + + /usr/local/bin/sigal.bin /mnt/public/www/example/images/.gallery + +Sigal depends on ``ffmpeg` for video thumbnailing and conversions. On CentOS 8, ffmpeg is in repository powertools. + +### Customized theme for sigal +Use theme `bgstack15-gallery-theme`, in any location. You just need to put its full path as the value of the theme in a sigal.conf.py for a gallery. +This is a fork of the default, included [colorbox](https://github.com/saimn/sigal/tree/master/sigal/themes/colorbox) theme. The full theme is available in this project directory, as well as a diff of it to the original as of sigal version 2.1.1. +The main changes are adding extra metadata handlers and link logic for the custom links related to editing metadata. + +### Customized sigal config for that theme +When you run `sigal init` in a directory, it generates a default config you can modify. The example theme, and this whole solution, depends on adding a number of settings.

File `60_regen_galery_sudo` adds the permission necessary. + +### CGI scripts for Apache httpd +The main focus of the gallery project is the ability to edit metadata from the web view. While sigal is great for developers, some users might only care about editing metadata from where they are actually viewing the media. +* edit.cgi is called from the custom theme's "edit" links, and includes the form for making changes to media metadata. +* apply.cgi actually makes the changes, and is called from the edit.cgi form. +* regen.cgi invokes sigal.bin which re-runs sigal. +* toggle-editing.cgi enables or disables editing. Enabling requires a password. +These can be placed anywhere you have enabled CGI for httpd, but the canonical location is `/var/www/cgi-bin/gallery/`. + +## Operations +I anticipate that more work is needed on an ongoing basis. Here are some processes that can be used. + +### Make a new gallery +To establish a new gallery, change directory to the source directory for the gallery and run command + + sigal.bin init + +Which generates the basic sigal.conf.py.

You need to include a path to the directory that holds a sigal.conf.py, or else a `gallery_id` from /etc/gallery-cgi.conf. + + sigal.bin example_images + +### Make metadata changes directly on filesystem +You can of course, as designed by the author of sigal, go edit any **${IMAGENAME%%.jpg}.md** file with the relevant fields. See references [1][r1] and [2][r2] for the available fields. +File index.md will be the metadata for the directory itself. + +## History +In 2020, I installed [piwigo](https://piwigo.org/) on a dev system.
