gulp-pragma

Gulp Pragma

A Gulp plugin to optionally remove pragma comments from your code that follow a particular pattern. Useful for JavaScript builds.

Installation  

npm install gulp-pragma

Simple Usage

Pass a simple config object to pragma() in your Gulp pipe. All the properties of the objects represent pragma tags. Set to false to remove them. Use all if you want to just remove all pragma blocks.

The system will look for sections of code that have this signature:

// To remove this section use: pragma({ debug: false })
/* pragma:DEBUG_START */
var a = true;
console.warn("a is", a);
/* pragma:DEBUG_END */

// To remove this section use: pragma({ amd: false })
/* pragma:AMD_START */
var a = true;
console.warn("a is", a);
/* pragma:AMD_END */

Use in your gulpfile:

var pragma = require('gulp-pragma');
gulp.src(['/**/*.js'])
.pipe(pragma({
    debug: false,
    amd: false
  }));

To remove all pragma blocks:

gulp.src(['/**/*.js'])
.pipe(pragma({
    all: false
  }));

Note: Its recommended you run this on your concatenated stream rather than your split-up file stream for performance reasons.
