Usage

First, install gulp-csstree as a development dependency:

`

Then, add it to your gulpfile.js:

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

gulp.task('css', function () {
gulp.src('./styles/*.css')
.pipe(csstree())
.pipe(gulp.dest('build'));
});
`

`js
var csstree = require('gulp-csstree');

gulp.task('css', function () {
gulp.src('./styles/*.css')
.pipe(csstree({ formatter: formatterFn }))
.pipe(gulp.dest('build'));
});
`
formatterFn is a function like this:
`js
function formatterFn(report, file) {
// some code, that outputs a report data...
}
`
Formatter function will be called for every file which has an invalid css.

Fail on errors

Pipe the file stream to csstree.failAfterError() to fail on errors.

`js
var csstree = require('gulp-csstree');

gulp.task('css', function () {
gulp.src('./styles/*.css')
.pipe(csstree())
.pipe(csstree.failAfterError())
.pipe(gulp.dest('build'));
});
