Trying to implement new rule for scss

[ChrisKam]

Hey Tony, thank you for all your awesome work on this and on CSSComb. My question does concern CSSComb but I'm pretty sure I can solve it myself once I learn how to add a new rule to gonzales-pe, more specifically I need to differentiate between @include one-liners like

@include font_size(0.85);

and multi-line includes like

@include breakpoint($breakpoint_tablet) {
    width: 50%;
}

This is actually already implemented internally by the standard checkInclude(i) function in the rules.js portion for SCSS by this function

    /**
     * Check if token is part of an included mixin like `@include nani(foo) {...}`
     * @param {Number} i Token's index number
     * @returns {Number} Length of the include
     */
    function checkInclude1(i) { ...

I would just need to make a rule to make this check seperately without lumping in all the other @include cases. In CSSComb, I could then do something like

if(currentNode[0] === 'include-multi-line') { ... }

I have tried hacking this in but I never made it execute up to the point of my custom function. I'm a total node.js noob unfortunately. Any help on this would be immensely appreciated, CSSComb now does almost everything I need perfectly :)

You can check if include node contains block in its content.
For example, from within dev branch:

var isMultiline = function(include) {
    return include.content.some(function(block) { return block.type === 'block' });
};

var css, include;

css = '@include font_size(0.85)';
include = gonzales.parse(css, { syntax: 'scss', rule: 'include' });
isMultiline(include); // returns `false`

css = '@include breakpoint($breakpoint_tablet) { width: 50%; }';
include = gonzales.parse(css, { syntax: 'scss', rule: 'include' });
isMultiline(include); // returns `true`

CSScomb will be moved to dev branch of this parser in a week or so.

Thank you for your super quick response, this solves it for me! I actually did something very similiar (though ugly and hack-ish), see: https://gist.github.com/thebugs/977813e0040a4145cf9d

I will reference your answer there as well.
