re2c is a tool for writing very fast and very flexible scanners. Unlike any other such tool, re2c focuses on generating high efficient code for regular expression matching. As a result this allows a much broader range of use than any traditional lexer offers. And Last but not least re2c generates

Ruby-WordNet is a Ruby interface to the WordNet® Lexical Database. WordNet? is an online lexical reference system whose design is inspired by current psycholinguistic theories of human lexical memory. English nouns, verbs, adjectives and adverbs are organized into synonym sets, each representing one

graylex offers a means to do string operations on input streams without slurping all input at once by using Common Lisp Gray Streams, fixed-sized and flexible buffers.
This is especially interesting for lexical analysis ("lexing") where input files can be exuberant, e.g. SQL dumps weighing hundreds of Megabytes.
Project Lestes is an ongoing effort to make a C++ compiler with comprehensive C++ source code using the most advanced algorithms seen. Other goals include: easilly retargettable compiler, compiler that can be successfully used in teaching compiler construction, compiler that can compile multitude of languages.
Epoche lexer is a scanner of C source files. It is intended to be used in lexical analysis of C source programs. Aim is to generate a high quality scanner that will detect lexical errors in C source code and provide clear diagnostic messages.
