================
Rewrite occurrences of filenames which have been renamed by gulp-rev
## Install
```bash
$ npm install --save-dev gulp-rev-replace
```
## Usage
Pipe through a stream which has both the files you want to be updated, as well as the files which have been renamed.
For example, we can use [gulp-useref](https://github.com/jonkemp/gulp-useref) to concatenate assets in an index.html,
and then use [gulp-rev](https://github.com/sindresorhus/gulp-rev) and gulp-rev-replace to cache-bust them.
```js
var gulp = require('gulp');
var rev = require('gulp-rev');
var revReplace = require('gulp-rev-replace');
var useref = require('gulp-useref');
var filter = require('gulp-filter');
var uglify = require('gulp-uglify');
var csso = require('gulp-csso');
gulp.task("index", function() {
var jsFilter = filter("**/*.js", { restore: true });
var cssFilter = filter("**/*.css", { restore: true });
var indexHtmlFilter = filter(['**/*', '!**/index.html'], { restore: true });
return gulp.src("src/index.html")
.pipe(useref()) // Concatenate with gulp-useref
.pipe(jsFilter)
.pipe(uglify()) // Minify any javascript sources
.pipe(jsFilter.restore)
.pipe(cssFilter)
.pipe(csso()) // Minify any CSS sources
.pipe(cssFilter.restore)
.pipe(indexHtmlFilter)
.pipe(rev()) // Rename the concatenated files (but not index.html)
.pipe(indexHtmlFilter.restore)
.pipe(revReplace()) // Substitute in new filenames
.pipe(gulp.dest('public'));
});
```
It is also possible to use gulp-rev-replace without gulp-useref:
```js
var rev = require("gulp-rev");
var revReplace = require("gulp-rev-replace");
gulp.task("revision", ["dist:css", "dist:js"], function(){
return gulp.src(["dist/**/*.css", "dist/**/*.js"])
.pipe(rev())
.pipe(gulp.dest(opt.distFolder))
.pipe(rev.manifest())
.pipe(gulp.dest(opt.distFolder))
})
gulp.task("revreplace", ["revision"], function(){
var manifest = gulp.src("./" + opt.distFolder + "/rev-manifest.json");
return gulp.src(opt.srcFolder + "/index.html")
.pipe(revReplace({manifest: manifest}))
.pipe(gulp.dest(opt.distFolder));
});
```
## API
### revReplace(options)
#### options.canonicalUris
Type: `boolean`
Default: `true`
Use canonical Uris when replacing filePaths, i.e. when working with filepaths
with non forward slash (`/`) path separators we replace them with forward slash.
#### options.replaceInExtensions
Type: `Array`
Default: `['.js', '.css', '.html', '.hbs']`
Only substitute in new filenames in files of these types.
#### options.prefix
Type: `string`
Default: ``
Add the prefix string to each replacement.
#### options.manifest
Type: `Stream` (e.g., `gulp.src()`)
Read JSON manifests written out by `rev`. Allows replacing filenames that were
`rev`ed prior to the current task.
#### options.modifyUnreved, options.modifyReved
Type: `Function`
Modify the name of the unreved/reved files before using them. The filename is
passed to the function as the first argument.
For example, if in your manifest you have:
```js
{"js/app.js.map": "js/app-98adc164.js.map"}
```
If you wanted to get rid of the `js/` path just for `.map` files (because they
are sourcemaps and the references to them are relative, not absolute) you could
do the following:
```js
function replaceJsIfMap(filename) {
if (filename.indexOf('.map') > -1) {
return filename.replace('js/', '');
}
return filename;
}
return gulp.src(opt.distFolder + '**/*.js')
.pipe(revReplace({
manifest: manifest,
modifyUnreved: replaceJsIfMap,
modifyReved: replaceJsIfMap
}))
.pipe(gulp.dest(opt.distFolder));
```
