NAME
yyfix - extract tables from y.tab.c
SYNOPSIS
yyfix file [tables]
DESCRIPTION
Programs have historically used a script (often named :yyfix) to extract
tables from the yacc(1) generated file y.tab.c. As the names of the
tables generated by the current version of yacc are different from those
of historical versions of yacc, the shell script yyfix is provided to
simplify the transition.
The first (and required) argument to yyfix is the name of the file where
the extracted tables should be stored.
If further command line arguments are specified, they are taken as the
list of tables to be extracted. Otherwise, yyfix attempts to determine
if the y.tab.c file is from an old or new yacc(1), and extracts the
appropriate tables.
The tables "yyexca", "yyact", "yypact", "yypgo", "yyr1", "yyr2", "yychk",
and "yydef" are extracted from historical versions of yacc(1).
The tables "yylhs", "yylen", "yydefred", "yydgoto", "yysindex",
"yyrindex", "yygindex", "yytable", "yyname", "yyrule", and "yycheck", are
extracted from the current version of yacc(1).
FILES
