can't handle HTML5 type DOMStringList

[davidflanagan]

The parser can't parse the type DOMSringList, or, in general any type name that has one of the primitive WebIDL types as a prefix. So longStringList would also not parse. I don't know if this is a problem with the grammar or the parser generator. But consider this line from node/WebIDLParser.js:

                if (input.substr(pos, 9) === "DOMString") {
                  var result4 = "DOMString"
                  pos += 9;

It looks ahead for known type names, but doesn't verify that they are at token boundaries.

Do you have a test handy? I think it's a problem with the grammar and I think I know how to fix it, but a copy of the IDL you're trying to parse (not just the bits that break) would be helpful. It's probably a problem with the grammar.

When I try to parse this (straight from the HTML5 spec):

interface HTMLPropertiesCollection : HTMLCollection {
caller getter PropertyNodeList namedItem(in DOMString name);
readonly attribute DOMStringList names;
};

I get this:

node.js:114
throw e; // process.nextTick error, or 'error' event on first tick
^
Expected "?", "[]" or [ \r\n
] but "L" found.

If I change DOMStringList to DOMString or StringList it parses. If I change it to "octet" it parses. But if I change it to "octetTest", it doesn't parse. This time, the error is on the "T" (in Test) instead of the L in List.
