- 1 BISON
-
- The BISON command invokes the GNU BISON parser generator.
-
- BISON file-spec
-
- 2 Parameters
-
- file-spec
-
- Here file-spec is the grammar file name, which usually ends in with
- _tab.c. Thus, the command bison foo.y yields foo_tab.c.
-
- 2 Qualifiers
-
- The following is the list of available qualifiers for BISON:
- /DEBUG
- /DEFINES
- /FILE_PREFIX=prefix
- /FIXED_OUTFILES
- /NAME_PREFIX=prefix
- /NOLINES
- /OUTPUT=outfilefile
- /VERBOSE
- /VERSION
- /YACC
-
- 2 /DEBUG
-
- Output a definition of the macro YYDEBUG into the parser file, so
- that the debugging facilities are compiled.
-
- 2 /DEFINES
-
- Write an extra output file containing macro definitions for the token
- type names defined in the grammar and the semantic value type
- YYSTYPE, as well as a extern variable declarations.
-
- If the parser output file is named "name.c" then this file is named
- "name.h".
-
- This output file is essential if you wish to put the definition of
- yylex in a separate source file, because yylex needs to be able to
- refer to token type codes and the variable yylval.
-
- 2 /FILE_PREFIX
-
- /FILIE_PREFIX=prefix
-
- Specify a prefix to use for all Bison output file names. The
- names are chosen as if the input file were named prefix.c
-
- 2 /FIXED_OUTFILES
-
- Equivalent to /OUTPUT=y_tab.c; the parser output file is called
- y_tab.c, and the other outputs are called y.output and y_tab.h. The
- purpose of this switch is to imitate Yacc's output file name
- conventions. The /YACC qualifier is functionally equivalent to
- /FIXED_OUTFILES. The following command definition will work as a
- substitute for Yacc:
- $YACC:==BISON/FIXED_OUTFILES
-
- 2 /NAME_PREFIX
-
- /NAME_PREFIX=prefix
-
- Rename the external symbols used in the parser so that they start
- with "prefix" instead of "yy". The precise list of symbols renamed
- is yyparse, yylex, yyerror, yylval, yychar and yydebug. For example,
- if you use /NAME_PREFIX="c", the names become cparse, clex, and so
- on.
-
- 2 /NOLINES
-
- Don't put any "#line" preprocessor commands in the parser file.
- Ordinarily Bison puts them in the parser file so that the C compiler
- and debuggers will associate errors with your source file, the
- grammar file. This option causes them to associate errors with the
- parser file, treating it an independent source file in its own right.
-
- 2 /OUTPUT
-
- /OUTPUT=outfile
-
- Specify the name "outfile" for the parser file.
-
- 2 /VERBOSE
-
- Write an extra output file containing verbose descriptions of the
- parser states and what is done for each type of look-ahead token in
- that state.
-
- This file also describes all the conflicts, both those resolved by
- operator precedence and the unresolved ones.
-
- The file's name is made by removing _tab.c or .c from the parser
- output file name, and adding .output instead.
-
- Therefore, if the input file is foo.y, then the parser file is called
- foo_tab.c by default. As a consequence, the verbose output file is
- called foo.output.
-
- 2 /VERSION
-
- Print the version number of Bison.
-
- 2 /YACC
-
- See /FIXED_OUTFILES.
