# gulp-header [![NPM version](https://badge.fury.io/js/gulp-header.png)](http://badge.fury.io/js/gulp-header) [![Build Status](https://travis-ci.org/tracker1/gulp-header.svg?branch=master)](https://travis-ci.org/tracker1/gulp-header)
gulp-header is a [Gulp](https://github.com/gulpjs/gulp) extension to add a header to file(s) in the pipeline. [Gulp is a streaming build system](https://github.com/gulpjs/gulp) utilizing [node.js](http://nodejs.org/).
## Install
```javascript
npm install --save-dev gulp-header
```
## Usage
```javascript
// assign the module to a local variable
var header = require('gulp-header');
// literal string
// NOTE: a line separator will not be added automatically
gulp.src('./foo/*.js')
.pipe(header('Hello'))
.pipe(gulp.dest('./dist/'))
// ejs style templating
gulp.src('./foo/*.js')
.pipe(header('Hello <%= name %>\n', { name : 'World'} ))
.pipe(gulp.dest('./dist/'))
// ES6-style template string
gulp.src('./foo/*.js')
.pipe(header('Hello ${name}\n', { name : 'World'} ))
.pipe(gulp.dest('./dist/'))
// using data from package.json
var pkg = require('./package.json');
var banner = ['/**',
' * <%= pkg.name %> - <%= pkg.description %>',
' * @version v<%= pkg.version %>',
' * @link <%= pkg.homepage %>',
' * @license <%= pkg.license %>',
' */',
''].join('\n');
gulp.src('./foo/*.js')
.pipe(header(banner, { pkg : pkg } ))
.pipe(gulp.dest('./dist/'))
// reading the header file from disk
var fs = require('fs');
gulp.src('./foo/*.js')
.pipe(header(fs.readFileSync('header.txt', 'utf8'), { pkg : pkg } ))
.pipe(gulp.dest('./dist/'))
// for use with coffee-script
return gulp.src([
'src/*.coffee',
])
.pipe(header(banner, { pkg : pkg } ))
.pipe(sourcemaps.init()) // init sourcemaps *after* header
.pipe(coffee({
bare: true
}))
.pipe(sourcemaps.write('.'))
.pipe(gulp.dest('dist/js'))
```

## API
### header(text, data)
#### text
Type: `String`
Default: `''`
The template text.
#### data
Type: `Object`
Default: `{}`
The data object used to populate the text.
In addition to the passed in data, `file` will be the stream object for the file being templated against and `filename` will be the path relative from the stream's basepath.
*NOTE: using `false` will disable template processing of the header*
