gulp.task('default', function () {
	gulp.src(SRC)

API

changed(dest, options)

dest

Type: String

The destination directory. Same as you put into gulp.dest().

This is needed to be able to compare the current files with the destination files.

options

Type: Object

Set options.extension value to specify extension of the destination files.

gulp.task('jade', function() {
	gulp.src('./src/**/*.jade')
		.pipe(changed('./app/', { extension: '.html' }))
		.pipe(jade())
		.pipe(gulp.dest('./app/'))
});
