Usage examples

Using with gulp

var gpp = require('gulp-gpp');

	return gulp
			.src('./lib/*.js')
			.pipe(gpp())
			.on('error', function(err){
				console.log('Preprocessig error');	// Actual error log is in gpp.log file
				cb();
			})
			.pipe(gulp.dest('./dist'));
});

Using with conventional streams

var gpp = require('gulp-gpp')

	fs
	.createReadStream('lib/myfile.js')
	.pipe(gpp({ gulp: false }))
	.on('error', function(err){
		console.log('Preprocessig error');	// Actual error log is in gpp.log file
	})
	.pipe(createWriteStream('dist/myfile.js'));
