Doesn't work with gulp-postcss

[TrySound]

[01:58:05] TypeError in plugin 'gulp-postcss'
Message:
    Object.keys called on non-object

With standard config everything fine. Maybe some rules somehow break warnings?

I can't seem to replicate this. No warnings with stylelint-config-cssrecipes@2.0.0, gulp-postcss@6.0.1 and gulp@3.9.0.

My gulpfile is this:

var postcss = require('gulp-postcss');
var gulp = require('gulp');
var stylelint = require('stylelint');

gulp.task('default', function () {
    var processors = [stylelint()];
    return gulp.src('css/temp.css')
        .pipe(postcss(processors));
});

And the config specified in the package.json:

{
  "stylelint": {
    "extends": "stylelint-config-cssrecipes"
  }
}

Can you please paste your gulpfile here so we can try to get to the bottom of this? :)

And what version are you using @TrySound ?

Seems like the problem since indentation rule in postcssPlugin.js

indentation: [ 2, 2, { hierarchicalSelectors: true } ]

Here is number

[TrySound]

Yep. Actual is not checked. Only possible.

This works fine.

indentation: 2

[TrySound]

Oh, I understand. It can't validate old syntax. But should.

Think we should also check the second element here
