Description:

CDL3 is an implementation language based on affix grammars. It rides
the borderline between syntactic formalism and programming language,
and tries to combine the good properties of both. The control
structure and data structures have been choosen such that it is
extremely easy to write deterministic parsers and transducers in CDL3.
In this sense, CDL3 is a Compiler Description Language (hence the
acronym). Its applicability is, however, not limited to compiler
construction. The language is wellsuited, more in general, for all
applications that can be characterized as syntax-directed:
communication between processes (human and machine) adhering to
well-established protocols, or interpreter-like systems, interactively
obeying a set of commands.
