| 41 | .Nm yyfix |
| 42 | .Ar file |
| 43 | .Op Ar tables |
| 44 | .Sh DESCRIPTION |
| 45 | Programs have historically used a script (often named ``:yyfix'') to |
| 46 | extract tables from the |
| 47 | .Xr yacc 1 |
| 48 | generated file |
| 49 | .Pa y.tab.c . |
| 50 | As the names of the tables generated by the current version of |
| 51 | .Xr yacc |
| 52 | are different from those of historical versions of |
| 53 | .Xr yacc , |
| 54 | the shell script |
| 55 | .Nm yyfix |
| 56 | is provided to simplify the transition. |
| 57 | .Pp |
| 58 | The first (and required) argument to |
| 59 | .Nm yyfix |
| 60 | is the name of the file where the extracted tables should be stored. |
| 61 | .Pp |
| 62 | If further command line arguments are specified, they are taken as |
| 63 | the list of tables to be extracted. |
| 64 | Otherwise, |
| 65 | .Nm yyfix |
| 66 | attempts to determine if the |
| 67 | .Pa y.tab.c |
| 68 | file is from an old or new |
| 69 | .Xr yacc , |
| 70 | and extracts the appropriate tables. |
| 71 | .Pp |
| 72 | The tables |
| 73 | .Dq yyexca , |
| 74 | .Dq yyact , |
| 75 | .Dq yypact , |
| 76 | .Dq yypgo , |
| 77 | .Dq yyr1 , |
| 78 | .Dq yyr2 , |
| 79 | .Dq yychk , |
| 80 | and |
| 81 | .Dq yydef |
| 82 | are extracted |
| 83 | from historical versions of |
| 84 | .Xr yacc . |
| 85 | .Pp |
| 86 | The tables |
| 87 | .Dq yylhs , |
| 88 | .Dq yylen , |
| 89 | .Dq yydefred , |
| 90 | .Dq yydgoto , |
| 91 | .Dq yysindex , |

| 93 | .Dq yygindex , |
| 94 | .Dq yytable , |
| 95 | .Dq yyname , |
| 96 | .Dq yyrule , |
| 97 | and |
| 98 | .Dq yycheck , |
| 99 | are extracted from the current version of |
