Installation

var gulp = require('gulp');
var changed = require('gulp-changed');
var sass = require('gulp-sass');

var sassDataURI = require('lib-sass-data-uri');

gulp.task('build-css', function() {
  return gulp.src('**/*.scss')
    .pipe(changed('dist/', {extension: '.scss'}))
    .pipe(sass({
      errLogToConsole: true,
      functions: Object.assign(sassDataURI, {other: function() {}})
    }))
    .pipe(gulp.dest('dist/'));
});
