.Sh SYNOPSIS

.Ar file
|
|
.Op Ar tables
|
|
.Sh DESCRIPTION
|
|
Programs have historically used a script (often named
|
|
.Dq :yyfix )
|
|
to extract tables from the
|
|
.Xr yacc 1
|
|
generated file
|
|
.Pa y.tab.c .
|
|
As the names of the tables generated by the current version of
|
|
.Xr yacc
|
|
are different from those of historical versions of
|
|
.Xr yacc ,
|
|
the shell script
|
|
.Nm
|
|
is provided to simplify the transition.
|
|
.Pp
|
|
The first (and required) argument to
|
|
.Nm
|
|
is the name of the file where the extracted tables should be stored.
|
|
.Pp
|
|
If further command line arguments are specified, they are taken as
|
|
the list of tables to be extracted.
|
|
Otherwise,
|
|
.Nm
|
|
attempts to determine if the
|
|
.Pa y.tab.c
|
|
file is from an old or new
|
|
.Xr yacc ,
|
|
and extracts the appropriate tables.
|
|
.Pp
|
|
The tables
|
|
.Dq yyexca ,
|
|
.Dq yyact ,
|
|
.Dq yypact ,
|
|
.Dq yypgo ,
|
|
.Dq yyr1 ,
|
|
.Dq yyr2 ,
|
|
.Dq yychk ,
|
|
and
|
|
.Dq yydef
|
|
are extracted
|
|
from historical versions of
|
|
.Xr yacc .
|
|
.Pp
|
|
The tables
|
|
.Dq yylhs ,
|
|
.Dq yylen ,
|
|
.Dq yydefred ,
|
|
.Dq yydgoto ,
|
|

.Dq yygindex ,

.Dq yytable ,
|
|
.Dq yyname ,
|
|
.Dq yyrule ,
|
|
and
|

are extracted from the current version of
