def loadBaseRulz
    Treetop.load("#{File.dirname(__FILE__)}/dataMetaParse/basic")
end

.parse(parser, source) ⇒ Object

Parse with error handling, convenience shortcut to the content of this method.

Parameters:

  • parser (Object) —

    Treetop compiled parser whichever class it is. It may be Treetop::Runtime::CompiledParser

  • source (String) —

    the data to parse with the given parser

Returns:

  • (Object) —

    either the AST, likely as Treetop::Runtime::SyntaxNode if the parsing was successful or Err if it was not or nil if there is no match. It’s not very consistent of when you get an Err or when you get a nil, it’s not exact science. One way to get a nil is to cause mismatch in the very first token.
