Merr: an LR Syntax Error Message Tool
page last updated: 2/21/21
Merr is a syntax error message table generator that works with
YACC and related LR-parser generators such as byacc and bison. Merr was
developed in support of the Unicon programming
language implementation. It is now available as a standalone tool for use
in compiler writing and compiler instruction. At present Merr supports
parsers generated for the C/C++ and Icon/Unicon programming languages;
the author is happy to assist people interested in porting Merr for use
with other LR parser generator systems, target languages, and machine
platforms.
