Is there something similar for HAML? Watcher needed.

PrePros can work with haml
or you can use gulp

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

gulp.task('haml', function () {
  gulp.src('./haml/blue/*.haml')
    .pipe(haml())
    .pipe(gulp.dest('./haml/blue'));
});

gulp.task('watch-haml', function() {
  gulp.watch(('./haml/blue/*.haml', ['haml']);
});

and run
gulp watch-haml
