Compile LiveScript to JavaScript for Gulp
Installation
npm i --save gulp-livescriptInformation
| Package | gulp-livescript |
| Description | Compile LiveScript to JavaScript for Gulp |
| Node Version | >= 0.10 |
| Gulp Version | >= 3.5.0 |
Example
See how we compile src/index.ls to lib/index.js in this project.
Notice: I used gulpfile to compile src to lib in the old days, now I use lsc compiler directly.
Usage
var gulpLiveScript = require('gulp-livescript');
gulp.task('ls', function() {
return gulp.src('./src/*.ls')
.pipe(gulpLiveScript({bare: true})
.on('error', gutil.log))
.pipe(gulp.dest('./public/'));
});Error Handling
gulp-livescript will emit an error for cases such as invalid LiveScript syntax.
If you need to exit gulp with non-0 exit code, attatch a lister and throw the error:
gulp.task 'build' ->
return gulp.src 'test/fixtures/illegal.ls'
.pipe gulp-livescript bare: true
.on 'error' -> throw it
.pipe gulp.dest '.'Options
The options object supports the same options as the standard LiveScript compiler.
Source maps
gulp-livescript can be used in tandem with gulp-sourcemaps to generate source maps for the livescript to javascript transition. You will need to initialize gulp-sourcemaps prior to running the gulp-livescript compiler and write the source maps after.
var sourcemaps = require('gulp-sourcemaps');
gulp.src('./src/*.ls')
.pipe(sourcemaps.init())
.pipe(livescript())
.pipe(sourcemaps.write())
.pipe(gulp.dest('./dest/js'));
// will write the source maps inline in the compiled javascript filesBy default, gulp-sourcemaps writes the source maps inline in the compiled javascript files. To write them to a separate file, specify a relative file path in the sourcemaps.write() function.
var sourcemaps = require('gulp-sourcemaps');
gulp.src('./src/*.ls')
.pipe(sourcemaps.init())
.pipe(livescript({ bare: true })).on('error', gutil.log)
.pipe(sourcemaps.write('./maps'))
.pipe(gulp.dest('./dest/js'));
// will write the source maps to ./dest/js/mapsContributing
