build tag file indexes of source code definitions

ctags parses source code and produces a sort of index mapping the names of significant entities (e.g. functions, classes, variables) to the location where that entity is defined. This index is used by editors like vi and emacsen to allow moving to the definition of a user-specified entity.

compiles finite state machines into code in various languages

ragel

compiles finite state machines into code in various languages

Ragel compiles finite state machines from regular languages into C, C++, Objective-C, D, Ruby or Java code. Ragel allows the programmer to embed actions at any point in a regular language. Non-determinism can be controlled through the use of embedded priorities and guarded regular language operators. Ragel also supports the construction of scanners and the building of state machines using state-charts. Ragel can be used to create robust recognizers and parsers which run very fast. It can work with integer-sized alphabets and can compile large state machines. The generated code has no dependencies.
