Does anyone know the rules for valid Ruby variable names? Can it be matched using a RegEx?
UPDATE: This is what I could come up with so far:
^[_a-z][a-zA-Z0-9_]+$
Does this seem right?
Identifiers are pretty straightforward. They begin with letters or an underscore, and contain letters, underscore and numbers. Local variables can’t (or shouldn’t?) begin with an uppercase letter, so you could just use a regex like this.
