Hi Brian, I haven't tried it myself but you might look at JSLint for JavaScript files. A checker for .htm files may be more problematic because it may say the custom moi: elements aren't standard and it also won't like that moi.css is implicitly added to every file.

re: semicolons - I believe semi-colons at the end of lines are officially optional in JavaScript so it should still run without those but it is good practice to have them.
