> A [Gulp](https://github.com/gulpjs/gulp) plugin to remove sections of code from files based on conditions

## Install

```sh
npm install gulp-remove-code --save-dev
```

## Usage

```js
const removeCode = require('gulp-remove-code');

gulp.src('./src/*.js')
  .pipe(removeCode({ noDevFeatures: true }))
  .pipe(gulp.dest('./dist/'))

gulp.src('./src/*.js')
  .pipe(removeCode({ noDevFeatures: true, commentStart: '/*', commentEnd: '*/' }))
  .pipe(gulp.dest('./dist/'))

gulp.src('./src/*.coffee')
  .pipe(removeCode({ noDevFeatures: true }))
  .pipe(gulp.dest('./dist/'))
```

## Examples

### Remove code from HTML files

```html
<div>
  
  <div class="sandbox-banner">Running in sandbox environment</div>

<span>Removing code is easy.</span>
</div>
```

```js
const removeCode = require('gulp-remove-code');

gulp.src('./src/file.html')
  .pipe(removeCode({ production: true }))
  .pipe(gulp.dest('./dist'))
```

The plugin will remove the code inside the comments, as well as the comments.

### Remove code JavaScript files

```js
let value = JSON.stringify({key: 'value'});

//removeIf(production)
value = JSON.stringify({key: 'value', production: true}, null, 2);
//endRemoveIf(production)

//removeIf(!development)
value = JSON.stringify({key: 'value', development: false}, null, 2);
//endRemoveIf(!development)

```

```js
const removeCode = require('gulp-remove-code');

gulp.src('./src/file.js')
  .pipe(removeCode({ production: true }))
  .pipe(gulp.dest('./dist'))
```

The plugin will remove the code inside the comments, as well as the comments.

### Advanced usage

Starting with version 2 of this plugin, conditions can also be expressed using the `!` specifier.

```js
// Remove code using *!* (negated) conditions

//----------- gulpfile.js -----------
//
const removeCode = require('gulp-remove-code');

gulp.src('./src/file.js')
  .pipe(removeCode({ production: false }))
  .pipe(gulp.dest('./dist'))

//----------- app-file.js -----------
//
//removeIf(!production)
value = JSON.stringify({key: 'value', production: false}, null, 2);
//endRemoveIf(!production)

```
