The Mystro system: A comprehensive translator toolkit
Mystro is a system that facilities the construction of compilers, assemblers, code generators, query interpretors, and similar programs. It provides features to encourage the use of iterative enhancement. Mystro was developed in response to the needs of NASA Langley Research Center (LaRC) and enjoys a number of advantages over similar systems. There are other programs available that can be used in building translators. These typically build parser tables, usually supply the source of a parser and parts of a lexical analyzer, but provide little or no aid for code generation. In general, only the front end of the compiler is addressed. Mystro, on the other hand, emphasizes tools for both ends of a compiler
The ModelCC Model-Driven Parser Generator
Syntax-directed translation tools require the specification of a language by
means of a formal grammar. This grammar must conform to the specific
requirements of the parser generator to be used. This grammar is then annotated
with semantic actions for the resulting system to perform its desired function.
In this paper, we introduce ModelCC, a model-based parser generator that
decouples language specification from language processing, avoiding some of the
problems caused by grammar-driven parser generators. ModelCC receives a
conceptual model as input, along with constraints that annotate it. It is then
able to create a parser for the desired textual syntax and the generated parser
fully automates the instantiation of the language conceptual model. ModelCC
also includes a reference resolution mechanism so that ModelCC is able to
instantiate abstract syntax graphs, rather than mere abstract syntax trees.Comment: In Proceedings PROLE 2014, arXiv:1501.0169
