- .Sh NAME
- .Nm yyfix
- .Nd extract tables from y.tab.c
- .Sh SYNOPSIS
- .Nm
- .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 1
- are different from those of historical versions of
- .Xr yacc 1 ,
- 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 1 ,
- 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 1 .

- .Dq yytable ,
