gulp-listfiles

Create a list of files and perform an action on each file in the list then write the results to a file.

Getting Started

This plugin is a gulp version of grunt-listfiles.

If you haven't used Gulp before, be sure to check out the Getting Started guide, as it explains how to create a Gulpfile as well as install and use Gulp plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install gulp-listfiles --save-dev

This option will hold all your pattern/replacement pairs. A pattern/replacement pair should contain key:value pairs containing:

• pattern String or Regex
• replacement String or Function

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

var options = {
  filename: 'output.txt',
  replacements: [{
    pattern: /\/(asdf|qwer)\//ig,
    replacement: '"$1"'
  }, {
    pattern: ',',
    replacement: ';'
  }, {
    pattern: /(file)(_)([\S]*?)(_)(test)/gi,
    replacement: function (match, p1, p2, p3, p4, p5, offset, string) {
      return [p1, p3, p5].join('-');
    }
  }]
};

gulp.task('listfiles', function () {
  return gulp.src(['src/**/*.js'], {read: false})
             .pipe(listfiles(options))
             .pipe(gulp.dest('tmp'));

Note

If specifying a function as a parameter for the replacemnt please see the documentation at https://developer.mozilla.org for more details. If the pattern is a string, only the first occurrence will be replaced, as stated on String.prototype.replace.

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Gulp.
