This is a simple elixir script to version bump a mix project. This exists because I often forget to update sub versions and find it tedious to edit the file by hand each time. Maybe you do too?

git clone https://github.com/MaxPower15/mixbump.git
cd mixbump
sudo cp mixbump /usr/bin/
sudo chmod +x /usr/bin/mixbump

The script assumes that the elixir binary exists at /usr/local/bin/elixir, which is the default after installing with homebrew on OSX. If it doesn't exist there for you, either change the script or add a symlink:

sudo ln -s `which elixir` /usr/local/bin/elixir

Bump sub version without staging or committing:

mixbump /path/to/mix.exs # trailing "mix.exs" can be omitted

Bump sub version and stage:

mixbump add /path/to/mix.exs
mixbump a /path/to/mix.exs

Bump sub version, stage, and commit

mixbump commit /path/to/mix.exs
mixbump c /path/to/mix.exs
