lexer

Single Line Operations Processor (SLOP) is an extensible expression language using it's own grammar system. Results are derived from expression strings which can be stored in anything i.e. database records, annotations in code, documents etc.

Utility for doing lexical parsing of some input. It is optimized for static (string) parsing, not partial input stream parsing, but contains tokenizer supporting either.

For my compiler theory class in college, the students each built a compiler from the ground up for a fictional language, C-. This is the lexer, which parses the text of the program into a tokenized format.
