string mutation library for gulp

gulp-insert

String manipulation library for gulp

Usage

npm install gulp-insert

var insert = require('gulp-insert');

Append

Appends a string onto the contents.

.pipe(insert.append('world')); // Appends 'world' to the contents of every file

Prepend

Prepends a string onto the contents.

.pipe(insert.prepend('Hello')); // Prepends 'Hello' to the contents of every file

Wrap

Wraps the contents with two strings.

.pipe(insert.wrap('Hello', 'World')); // prepends 'hello' and appends 'world' to the contents

Transform

Calls a function with the contents of the file.

.pipe(insert.transform(function(contents, file) {
  return contents.toUpperCase();
}));

Transform has access to the underlying vinyl file. The following code adds a '//' comment with the full file name before the actual content.

.pipe(insert.transform(function(contents, file) {

	var comment = '// local file: ' + file.path + '\n';
	return comment + contents;
}));

See https://github.com/wearefractal/vinyl for docmentation on the 'file' parameter.
