## Breaking changes and updates


### v2.0.0

Included `commit_template` option, allows to customize commit outputs.

You can use the following commit properties:
- commit.subject
- commit.body
- commit.link
- commit.hash
- commit.breaks
- commit.type
- commit.component
- closes: String containing the issues closed
- link: Link to the commit
- ~~commit.author~~

### V1.0.0

Since version `1.0.0` git-changelog has included the [`.changelogrc` specification](#changelogrc-specification) and has discontinued the next options:
- `grep_commits` option has been removed in favour of the `.changelogrc` options
- `repo_url` fixed as parameter
- `branch_name` changed to `branch`

#### v1.1.0
- `version_name` instead of `version`



## `.changelogrc` specification

The `.changelogrc` file contains the "standard commit guideliness" that you and your team are following.

This specification is used to grep the commits on your log, it contains a valid JSON that will tell git-changelog which sections to include on the changelog.

## The "git_changelog" task

### Grunt Task

#### Getting Started
This plugin requires Grunt `1.0.0`

If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to create a [Gruntfile](http://gruntjs.com/sample-gruntfile) as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

```shell
npm install git-changelog --save-dev
```

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

```js
grunt.loadNpmTasks('git-changelog');
```


In your project's Gruntfile, add a section named `git_changelog` to the data object passed into `grunt.initConfig()`.

```js
grunt.initConfig({
  git_changelog: {
    minimal: {
      options: {
        file: 'MyChangelog.md',
        app_name : 'Git changelog',
        changelogrc : '/files/.changelogrc',
        logo : 'https://github.com/rafinskipg/git-changelog/raw/master/images/git-changelog-logo.png',
        intro : 'Git changelog is a utility tool for generating changelogs. It is free and opensource. :)'
      }
    },
    extended: {
      options: {
        app_name : 'Git changelog extended',
        file : 'EXTENDEDCHANGELOG.md',
        version_name : 'squeezy potatoe',
        sections : [
          {
            "title": "Test commits",
            "grep": "^test"
          },
          {
            "title": "New Awesome Features!",
            "grep": "^feat"
          }
        ],
        debug: true,
        tag : false //False for commits since the beggining
      }
    },
    fromCertainTag: {
      options: {
        repo_url: 'https://github.com/rafinskipg/git-changelog',
        app_name : 'My project name',
        file : 'tags/certainTag.md',
        tag : 'v0.0.1'
      }
    },
    customTemplate: {
      options: {
        app_name : 'Custom Template',
        intro: 'This changelog is generated with a custom template',
        file: 'output/customTemplate.md',
        template: 'templates/template_two.md',
        logo : 'https://github.com/rafinskipg/git-changelog/raw/master/images/git-changelog-logo.png',
        version_name : 'squeezy potatoe',
        tag: 'v0.0.1',
        debug: true
      }
    }
  }
})
```

## Git Commit Guidelines - Source : "Angular JS"

We have very precise rules over how our git commit messages can be formatted.  This leads to **more
readable messages** that are easy to follow when looking through the **project history**.  But also,
we use the git commit messages to **generate the AngularJS change log**.

### Commit Message Format
Each commit message consists of a **header**, a **body** and a **footer**.  The header has a special
format that includes a **type**, a **scope** and a **subject**:

```
<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>
```

Any line of the commit message cannot be longer 100 characters! This allows the message to be easier
to read on github as well as in various git tools.

Example commit messages

```
git commit -m "docs(readme): Add documentation for explaining the commit message"
git commit -m "refactor: Change other things"
```

Closing issues : 

```
git commit -m "fix(git_changelog_generate): pass tag if it exists to gitReadLog
Previously if a tag was found the script would try to find commits
between undefined..HEAD. By passing the tag, it now finds tags between
tag..HEAD.

Closes #5."
```

### Example types

**You may define your own types refering to the `.changelogrc` specification**

Must be one of the following:

* **feat**: A new feature
* **fix**: A bug fix
* **docs**: Documentation only changes
* **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
* **refactor**: A code change that neither fixes a bug or adds a feature
* **test**: Adding missing tests
* **chore**: Changes to the build process or auxiliary tools and libraries such as documentation generation


### Scope
The scope could be anything specifying place of the commit change. For example `$location`,
`$browser`, `$compile`, `$rootScope`, `ngHref`, `ngClick`, `ngView`, etc...

### Subject
The subject contains succinct description of the change:

* use the imperative, present tense: "change" not "changed" nor "changes"
* don't capitalize first letter
* no dot (.) at the end

###Body
Just as in the **subject**, use the imperative, present tense: "change" not "changed" nor "changes"
The body should include the motivation for the change and contrast this with previous behavior.

###Footer
The footer should contain any information about **Breaking Changes** and is also the place to
reference GitHub issues that this commit **Closes**.


A detailed explanation can be found in this [document][commit-message-format].

## Tagging your project

In order to have you project versions correctly displayed on your changelog, try to use this commit message format:

```
chore(release): v1.4.0 codename(jaracimrman-existence)
```

In order to do that, you can use git annotated tags:

```
git tag -a v1.4.0 -m 'chore(release): v1.4.0 codename(jaracimrman-existence)'
```

If you are publishing NPM modules you can let NPM [do that for you][npm-versioning]:

```
npm version patch -m "chore(release): %s codename(furious-stallman)"
```
