Usage

Basic Usage, No options.

var concatFilenames = require('gulp-concat-filenames');
 
var concatFilenamesOptions = {
 
};
 
function fileManifest(){
  gulp
      .src('./lib/**/*.*')
      .pipe(concatFilenames('manifest.txt', concatFilenamesOptions))
      .pipe(gulp.dest('./output/'));
}
 
 
gulp.task('file-manifest', fileManifest);
 

Arguments

Gulp concat-filenames takes 2 arguments: filename and options

Filename [Required]

This first argument is the name of the output file the list of filenames will be put into.

Options [Optional]

The second argument is optional (pun intended), and is an object with the following properties:

• newline - The character to use in place of \n for a newline. The default value will be \n
• prepend - Some text to prepend to every entry in the list of filenames
• append - Some text to append to every intry in the list of filenames
• template - a function that takes one parameter (the file name) and returns the string after some formatting. Can be used in addition to, or instead of, append and prepend
• root - the root folder. Including this argument will return a list of relative paths instead of absolute paths.

Examples

Given the file structure:

.
+-- somefile.txt
+-- lib
|   +-- one.txt
|   +-- two.txt
+-- gulpfile.js

var concatFilenames = require('gulp-concat-filenames');
 
var concatFilenamesOptions = {
    root: '/lib',
    prepend: '==> ',
    append: ' <=='
};
 
function fileManifest(){
  gulp
      .src('./lib/**/*.*')
      .pipe(concatFilenames('manifest.txt', concatFilenamesOptions))
      .pipe(gulp.dest('./output/'));
}
 
 
gulp.task('file-manifest', fileManifest);

running gulp file-manifest now produces a file called manifest.txt with the contents

==> one.txt <==
==> two.txt <==

Or you can use the template property, to format the output as well.

 
function fileNameFormatter(filename) {
   return 'XXX--' + filename.toUpperCase() + '--YYY';
}
 
var concatFilenames = require('gulp-concat-filenames');
 
var concatFilenamesOptions = {
    root: '/lib',
    template: fileNameFormatter // Pass in a function
};
 
function fileManifest(){
  gulp
      .src('./lib/**/*.*')
      .pipe(concatFilenames('manifest.txt', concatFilenamesOptions))
      .pipe(gulp.dest('./output/'));
}
 
 
gulp.task('file-manifest', fileManifest);

running gulp file-manifest now produces a file called manifest.txt with the contents

XXX--ONE.TXT--YYY
XXX--TWO.TXT--YYY
