Mix Tasks

Changex.Diff

If you run mix changex.diff then a diff based on your git commit history will be generated. This can be called in several way:

To generate a changelog from the most recent tag (the root commit will be used if there are no tags) to the git HEAD run:

mix changex.diff

To generate a changelog from a git reference (commit, tag, etc.) to HEAD run:

mix changex.diff a87a32f
mix changex.diff v0.1.0
mix changex.diff HEAD~5

To generate a changelog between two commit references:

mix changex.diff a87a32f v0.1.0
mix changex.diff v0.1.0 v0.1.1
mix changex.diff HEAD~5 HEAD~2

The following options are also available:
