#gulp-replace-template

Create your own templating syntax and replace with an object via gulp.

##Install

npm install --save-dev gulp-replace-template

===

##Usage

In your gulpfile:

1var gulp = require("gulp");
2var replaceTemplate = require("gulp-replace-template");
3
4gulp.task("replace", ["myDepTask"], function (cb) {
5  return gulp.src(["**/*"])
6          .pipe( replaceTemplate({
7            repKeyA: "REPLACEMENT TEXT",
8            repKeyB: "TEST",
9            repKeyC: "WORLD!"
10          }) )
11          .pipe( gulp.dest("./dist") )
12});

In the file you want to process:

This is a random text file.

Here is where I want my repKeyA.

Again, this is just a repKeyB.

HELLO repKeyC

The output from the gulp task pipe:

This is a random text file.

Here is where I want my REPLACEMENT TEXT.

Again, this is just a TEST.

HELLO WORLD!

###Advanced Usage: You can also use it to create your own (not-so-smart) templating engine (sort-of).

In your gulpfile:

1var gulp = require("gulp");
2var replaceTemplate = require("gulp-replace-template");
3
4function _randomString (len) {
5  var alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
6  var output = "";
7
8  for (var i = 0; i < len; i++) {
9    var randomNum = Math.floor( Math.random() * (alphabet.length - 0) ) + 0;
10
11    output += alphabet.charAt(randomNum);
12  }
13
14  return output;
15}
16
17gulp.task("replace", ["myDepTask"], function (cb) {
18  return gulp.src(["**/*.js"])
19          .pipe( replaceTemplate({
20            generatedVarName: _randomString(12),
21            generatedVarVal: Boolean(Math.floor(Math.random() * (1 - 0 + 1)) + 0),
22            defaultValForX: "foo",
23            newValForX: "bar"
24          }) )
25          .pipe( gulp.dest("./dist") )
26});

In the file you want to process:

1var {{generatedVarName}} = {{generatedVarVal}};
2
3var x = "{{defaultValForX}}";
4
5if ({{generatedVarName}} >= 3) {
6  x = "{{newValForX}}";
7}

The output from the gulp task pipe:

1var vAbGbaxJxtnc = true;
2
3var x = "foo";
4
5if (vAbGbaxJxtnc >= 3) {
6  x = "bar";
7}
