Digests and compresses static files for production deployment.

This task generates versions of static files with content-based hashes in their filenames and creates a manifest file mapping original names to their hashed versions.

$ mix francis.digest
$ mix francis.digest priv/static
$ mix francis.digest priv/static --output priv/static

Command line options

• --output - the output path for generated files. Defaults to the input path.

• --age - sets the cache control max age in seconds for static assets. This value is used for cache headers. Defaults to 31536000 (1 year).

• --gzip - when set to false, does not generate gzipped files. Defaults to true.

• --exclude - list of file patterns to exclude from digest. Example: --exclude '*.txt' --exclude '*.json'

The output will be a set of digested files along with a cache manifest file. The manifest file maps original file names to their digested counterparts.
