lesshint custom rule get the filename being walked

Question

I'm creating a custom linting rule in lesshint.

I want to access the filename of the file being walked.

Current code:

module.exports = {

    name: 'customrule',

    nodeTypes: ['decl'],



    lint: function(config, node) {        

        console.log(node.root().source.input.from);        

    }

};

The closest I've got is

node.root().source.input.from

which seems to output the index of the file, but not its name.

config

object seems to be a boolean

I've just pushed an update where the full file path will be included on all nodes. You can access it via the source property, like this:

module.exports = {
    name: 'customrule',
    nodeTypes: ['decl'],

    lint: function(config, node) {        
        console.log(node.source.input.file)     
    }
};

The value of config will be the value you specified for it in your .lesshintrc file. For example:

{
    "customrule": {
        "enabled": true,
        "option": false
    }
}

Will pass that object in config.
