Pattern-based Text Generator

The Pattern-Based Text Generator PTG supports translations into any kind of structured text. The structure of the target text is described by a set of patterns. PTG generates a set of functions for them. They are called to compose an instance of the target structure which is then output.

PTG is suitable to produce any kind of target language, e. g. programs of any programming language, special purpose languages like TeX or PostScript, or just structured data or tables in textual form.

PTG is typically applied for tasks of a language processor's translation phase. The calls of the patterns functions are then used in LIDO specifications to describe the translation of certain tree contexts. PTG may as well be used in C functions or in stand-alone C programs that translate some data structure into an output text.
