Rev and replace files according to their mutual dependencies. This plugin accepts a stream containing all the files to filerev and/or replace. It will detect which files reference which files, and then transform the files accordingly. For example, if we filerev and replace these files:

index.html: <img src="/loader.gif" /> <link href="/styles.css" type="text/css" />
loader.gif
styles.css: body {background: url("/loader.gif")}

The process will be the following (hashes are made up for the example):

1. Filerev loader.gif into loader-11111111.gif
2. Replace /loader.gif in index.html and styles.css
3. Filerev styles.css into styles-22222222.css
4. Replace /styles.css in index.html
5. Filerev index.html into index-33333333.html

Notice that loader.gif is filereved first, since it is referenced the most, then styles.css and finally index.html. The resulting stream will be:

loader-11111111.gif
styles-22222222.css: body {background: url("/loader-11111111.gif")}
index-33333333.html: <img src="/loader-11111111.gif" /> <link href="/styles-22222222.css" type="text/css" />

var filerevReplace = require('gulp-filerev-replace');

// Include all files to filerev and/or replace, making sure the base is correct
gulp.src('/mysite/**/*', {base: '/mysite'})
  .pipe(filerevReplace({
    filerev: ['assets/**/*'], // Select the files to filerev
    replace: ['views/**/*'],  // Select the files to replace
    base:    'assets'         // Filerevved files are served from the assets directory by the web server
  }))
  ...

• filerev: minimatch pattern to filter the files to filerev.
• replace: minimatch pattern to filter the files to replace.
• base: Directory from where the files are served by the web server. Optional, defaults to the file's base;

A second plugin is also available that adds a new file to the stream. This file contains a JSON list of all files that were filereved.

var filerevReplace = require('gulp-filerev-replace');

// Include all files to filerev and/or replace, making sure the base is correct
gulp.src('/mysite/**/*', {base: '/mysite'})
  .pipe(filerevReplace({
    filerev: ['assets/**/*'], // Select the files to filerev
    replace: ['views/**/*'],  // Select the files to replace
    base:    'assets'         // Filerevved files are served from the assets directory by the web server
  }))
  .pipe(filerevReplace.addManifest({path: 'assets/filerev.json'}))
  ...

The example above would add a new file in the stream, with path assets/filerev.json, containing something like:

{
  "assets/loader.gif": "assets/loader-11111111.gif",
  "assets/styles.css": "assets/styles-22222222.css"
}

options is an object containing the vinyl file options to use for the manifest file. It defaults to:

• path: filerev-replace-manifest.json

• Try to break this into simpler plugins...
• Handle null files
• Handle relative paths in current directory?
• Document matched patterns
