Two string comparisons in same expression fails #67

I have an object defined thus:

define Value {
    id : null,
    v : null,
    constructor : function (id, value) {
        this.id = id;
        this.v = value;
     }
}

I'm asserting a fact like this:

s.assert(new Value("xyz", "abc"));

Then looking for it in a when clause like this:

v4 : Value v4.id =~ /xyz/ && v4.v =~ /abc/;

The above fails to trigger the rule. The following does trigger the rule:

 v4 : Value v4.id =~ /xyz/ && v4.v ==  'abc';

For some reason, two string comparisons in the same rule don't want to play nice.

After some investigation there is an issue with parsing regexps in the constraint grammar which does a greedy match on the first regexp. Im working on fixing the parser for the regexp and will have a fix soon.

* Added ability to `import` other nools files to create composible rules files [#58](C2FO#58)
* When using `global` to require other files you can now require other files relative to the nools file
* Added uglify-js as a dependency instead of devDependency #71
* Fixed issue #61 where transpile would not properly escape `"` character.
* Fixed issue #66 and #67 where regular expression matching was too greedy.
* Fixed issue #62 where constraints with a `"` character would produce invalid javascript when `transpiling`.
* Fixed issue #69 where rules names with a `'` character in a rule would produce invalid javascript when `transpiling`.
