> Generate a changelog using [conventional-changelog](https://github.com/conventional-changelog/conventional-changelog)

*Issues with the output should be reported on the `conventional-changelog` [issue tracker](https://github.com/conventional-changelog/conventional-changelog/issues).*

Checkout the [gulp official recipe](https://github.com/gulpjs/gulp/blob/master/docs/recipes/automate-release-workflow.md) to automate releases with gulp and gulp-conventional-changelog.


## Install

```
$ npm install --save-dev gulp-conventional-changelog
```


## Usage

```js
import gulp from 'gulp';
import conventionalChangelog from 'gulp-conventional-changelog';

gulp.task('changelog', function () {
  return gulp.src('CHANGELOG.md')
    .pipe(conventionalChangelog({
      // conventional-changelog options go here
      preset: 'angular'
    }, {
      // context goes here
    }, {
      // git-raw-commits options go here
    }, {
      // conventional-commits-parser options go here
    }, {
      // conventional-changelog-writer options go here
    }))
    .pipe(gulp.dest('./'));
});
```

### streaming mode

```js
gulp.task('changelog', function () {
  return gulp.src('CHANGELOG.md', {
    buffer: false
  })
    .pipe(conventionalChangelog({
      preset: 'angular'
    }))
    .pipe(gulp.dest('./'));
});
```

### buffer mode

```js
gulp.task('changelog', function () {
  return gulp.src('CHANGELOG.md')
    .pipe(conventionalChangelog({
      preset: 'angular'
    }))
    .pipe(gulp.dest('./'));
});
```

**Note:** If your `options.releaseCount` is `0` (regenerate all changelog from previous releases) you can just use [conventional-changelog](https://github.com/conventional-changelog/conventional-changelog) directly or not to read the file at all.

```js
import gulp from 'gulp';
import conventionalChangelog from 'conventional-changelog';
import fs from 'fs';

gulp.task('default', function () {
  return conventionalChangelog({
    preset: 'angular',
    releaseCount: 0
  })
    .pipe(fs.createWriteStream('CHANGELOG.md'));
});
```

Or

```js
import gulp from 'gulp';
import conventionalChangelog from 'gulp-conventional-changelog';

gulp.task('default', function () {
  return gulp.src('CHANGELOG.md', {
    read: false
  })
    .pipe(conventionalChangelog({
      preset: 'angular',
      releaseCount: 0
    }))
    .pipe(gulp.dest('./'));
});
```
