Overview

package exception implements a Tokenizer which extracts pieces matched by a regular expression from the input data, delegates the rest to another tokenizer, then insert back extracted parts in the token stream. Use it to preserve sequences which a regular tokenizer would alter or remove.

Its constructor takes the following arguments:

"exceptions" ([]string): one or more Go regular expressions matching the sequence to preserve. Multiple expressions are combined with "|".

"tokenizer" (string): the name of the tokenizer processing the data not matched by "exceptions".
