Arguments code -- string of source code to parse, language -- formal language the code is written in, tokennames -- either 'long', 'short', or 'none' (see below). Merge subsequent tokens of the same token-type. Iterating over an instance yields the tokens as ``(tokentype, value)`` tuples. The value of `tokennames` configures the naming of the tokentype: 'long': downcased full token type name, 'short': short name defined by pygments.token.STANDARD_TYPES (= class argument used in pygments html output), 'none': skip lexical analysis. �shortc C sj || _ || _|| _d| _|dv s|dkrdS ts td��z t| j�| _W dS tjj y4 td| ��w )zE Set up a lexical analyzer for `code` in `language`.
