TREE-META
The TREE-META (aka Tree Meta and TREEMETA) Translator Writing System is a Compiler-compiler system for context-free languages originally developed in the 1960s. Parsing statements of the metalanguage resemble Augmented Backus–Naur Form with embedded tree-building directives. Unparsing〔 rules include extensive tree-scanning and code-generation constructs. ==History== TREE-META was instrumental in the development of the On-Line System and was ported to many systems including the Univac 1108, GE 645, SDS-940, ICL 1906A, PERQ, and UCSD p-System.〔
