"Executable textual modeling tools support automated code generation. For example, supports a number of high-level languages but is targeted towards text parsing and input validation. recently added built-in support for state machines. The State Machine Compiler (SMC) is targeted towards the specification of event driven systems. Microsoft is also developing a textual specification language, AsmL, based on state machine concepts. Those approaches do not incorporate class diagram abstractions and do not support development of complete applications. Executable UML supports a subset of UML textually but misses key features of UML and does not integrate with programming languages."
