pre-commit-annex hook script to automatically extract metadata from lots of types of files Using the extract(1) program to do the heavy lifting. Decided to make git-annex run pre-commit-annex when committing. Since git-annex pre-commit also runs it, it'll be run when git commit is run too, via the pre-commit hook. This basically gives back the pre-commit hook that git-annex took away. The implementation avoids repeatedly looking for the hook script when the assistant is running and committing repeatedly; only checks if the hook is available once. To make the script simpler, made git-annex metadata -s field?=value only set a field when it's not already got a value. This commit was sponsored by bak.

git-annex's [[metadata]] works best when files have a lot of useful
metadata attached to them.
To make git-annex automatically set the year and month when adding files,
The pre-commit-annex hook script that automatically extracts metadata has been updated to also use exiftool. Thanks, Klaus Ethgen.

A git commit hook can be set up to extract lots of metadata from files

like photos, mp3s, etc. Whenever annexed files are committed, their
metadata will be extracted and stored.
Download [[pre-commit-annex]] and install it in your git-annex repository
as `.git/hooks/pre-commit-annex`
Remember to make the script executable! `chmod +x .git/hooks/pre-commit-annex`

Install it from <http://www.gnu.org/software/libextractor/>
`apt-get install extract`
Configure which metadata fields to ask extract for: `git config metadata.extract "artist album title camera_make video_dimensions"`

i think i understand what that sed meant
2014-04-01 04:21:58 +00:00
To get a list of all possible fields, run: `extract -L | sed 's/ /_/g'`

### using exiftool
The git commit hook can also use exiftool to get metadata.
Install it from <http://owl.phy.queensu.ca/~phil/exiftool/>
`apt-get install libimage-exiftool-perl`
Configure which metadata fields to ask exiftool for: `git config metadata.exiftool "Model ImageSize FocusRange GPSAltitude GPSCoordinates"`
To get a list of all possible fields, run: `exiftool -list`
### using both extract and exiftool
If you want some metadata that extract knows about, and other metadata
that exiftool knows about, just install them both, and set both
`metadata.extract` and `metadata.exiftool`.

By default, if a git-annex already has a metadata field for a file,
its value will not be overwritten with metadata taken from files.
To allow overwriting, run: `git config metadata.overwrite true`
