grunt-autoprefixer breaks my code (theme)
#12452 adds grunt-autoprefixer this also means the less code is not any longer pre-fixed.
Unprefixed Less code breaks my WordPress theme.
The JBST WordPress theme (http://wordpress.org/themes/jbst) is based on Bootstrap 3. The theme also has a built-in Less compiler. The Less compiler has been build with less.php (http://lessphp.gpeasy.com/).
The theme includes / imports bootstrap.less and compiles the theme's css. Other Less code in the theme also depends of Bootstrap's Less, for instance of the Bootstrap's gradient mixins.
I found https://github.com/vladkens/autoprefixer-php already, but also these tool depends on node.js. The WordPress theme should only depend on PHP.
Adding the autoprefixer in the build process makes compiling Bootstrap's CSS dependent of node.js (and grunt), i understand the profits but for my it is a bad idea now.
NB also usage / compiling of for instance https://github.com/bassjobsen/bootstrap-a11y-theme becomes dependent of node.js now
