Allow defining custom functions from outside the less files

[slorber]

Hi,

This is related to less/less.js#2747

I'd like to be able to add custom functions for usage in mixin guards.

The thing is that I'm not really interested declaring these fonctions in Less syntax but just register some custom useful functions in my build process.

Is it possible to do?

Yes, you just write your own plugin. (There're actually two slightly different plugin formats currently - 1, 2).

Closing as out of the plugin scope.
