Line comment's text value not returned in the AST

[vecerek]

Hi Guys!

I'd like to ask you, what happens to the text value of line comments after parsing? When I get the AST, their value is an empty string. Block comment values are returned correctly.
Here I see, that the parser saves the comment's text value regardless its type.
Should I pass some extra option to the parser, or is it a bug?

Thanks in advance :)

This is my code for parsing:

var less = require('/usr/local/lib/node_modules/less/lib/less-node')
    , fs = require('fs')
    , path = require('path');

module.exports = {
    parse: function(src, isStdin) {
        // Parses a Less file and outputs its AST

        var visit = function(o) {
            // Attaches the node type to the necessary objects
            for (var p in o) {
                if (typeof o[p] == 'object') visit(o[p]);
            }
            if (o != null && o != "") {
                if ("type" in o) o["class"] = o.type;
            }
        };

        var code = src;
        var options = {};

        if (!isStdin) {
            code = fs.readFileSync(src, 'utf8').toString();
            options = {
                filename: path.resolve(src)
            }
        }

        return less.parse(code, options, function(e, tree) {
            if (!e) {
                visit(tree);
                console.log(JSON.stringify(tree, null, 2));
            } else {
                e.class = "error"
                console.log(JSON.stringify(e));
            }
        });
    }
};

And an extract from its output:

{
          "value": "/* Color Properties */",
          "isLineComment": false,
          "currentFileInfo": {
            "filename": "/Users/attila/Projects/OpenSource/less2sass-test/less2sass/tmp/less/test_rules.less",
            "rootpath": "",
            "currentDirectory": "/Users/attila/Projects/OpenSource/less2sass-test/less2sass/tmp/less/",
            "entryPath": "/Users/attila/Projects/OpenSource/less2sass-test/less2sass/tmp/less/",
            "rootFilename": "/Users/attila/Projects/OpenSource/less2sass-test/less2sass/tmp/less/test_rules.less"
          },
          "class": "Comment"
},
{
          "value": "",
          "isLineComment": true,
          "currentFileInfo": {
            "filename": "/Users/attila/Projects/OpenSource/less2sass-test/less2sass/tmp/less/test_rules.less",
            "rootpath": "",
            "currentDirectory": "/Users/attila/Projects/OpenSource/less2sass-test/less2sass/tmp/less/",
            "entryPath": "/Users/attila/Projects/OpenSource/less2sass-test/less2sass/tmp/less/",
            "rootFilename": "/Users/attila/Projects/OpenSource/less2sass-test/less2sass/tmp/less/test_rules.less"
          },
          "class": "Comment"
}
