## rebar3_bump
A rebar plugin to inspired by ruby's `bump` gem. This plugin can be used to manage package version.


## Build
```
$ rebar3 compile
```

## Use
Add the plugin to your rebar config:
```erlang
{project_plugins, [
	{rebar3_bump, "0.1.0"}
]}.
```
Then set the `vsn` attribute of `.app.src`/`relx` release configuration to `{cmd, "rebar3 bump"}`. An example `.app.src` is listed below
```erlang
{application, sample_app,
 [{description, "An OTP library"},
  {vsn, {cmd, "rebar3 bump"}},
  {registered, []},
  {applications,
   [kernel,
    stdlib
   ]},
  {env,[]},
  {modules, []},

  {licenses, ["Apache 2.0"]},
  {links, []}
 ]}.
 ```

Then just call your plugin directly in an existing application:
```bash
$ rebar3 bump [major|minor|patch|pre}
```
This plugin requires a configuration file `bump.config` to be present in your project. The file will get created if not present. The plugin also automatically appends git metadata to the version.
