|
||||
.skip
|
||||
file-spec
|
||||
.skip
|
||||
Here file-spec is the grammar file name, which usually ends in
|
||||
.y. The parser file's name is made by replacing the .y
|
||||
with _tab.c. Thus, the command bison foo.y yields
|
||||
foo_tab.c.

2 Qualifiers
|
||||
.skip
|
||||
The following is the list of available qualifiers for BISON:
|
||||
.literal
|
||||
/DEBUG
|
||||
/DEFINES
|
||||
/FILE_PREFIX=prefix
|
||||
/FIXED_OUTFILES
|
||||
/NAME_PREFIX=prefix
|
||||
/NOLINES
|
||||
/NOPARSER
|
||||
/OUTPUT=outfilefile
|
||||
/RAW
|
||||
/TOKEN_TABLE
|
||||
/VERBOSE
|
||||
/VERSION
|
||||
/YACC
|
||||
.end literal
|
||||
.skip
|
||||
.indent -1
|
||||
2 /DEBUG
|
||||
.skip
|
||||
In the parser file,
|
||||
define the macro YYDEBUG to 1 if it is not already defined,
|
||||
so that the debugging facilities are compiled.
|
||||
.skip
|
||||
.indent -1
|
||||
2 /DEFINES
|
||||
.skip
|
||||
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.
|
||||
.skip
|
||||
If the parser output file is named "name.c" then this file
|
||||
is named "name.h".
|
||||
.skip
|
||||
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.
|
||||
.skip
|
||||
.indent -1
|
||||
2 /FILE_PREFIX
|
||||
.skip
|
||||
.literal
|
||||
/FILIE_PREFIX=prefix
|
||||
.end literal
|
||||
.skip
|
||||
Specify a prefix to use for all Bison output file names. The names are
|
||||
chosen as if the input file were named prefix.c
|
||||
|
||||
.skip
|
||||
.indent -1
|
||||
2 /FIXED_OUTFILES
|
||||
.skip
|
||||
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:
|
||||
|
||||
.literal
|
||||
$YACC:==BISON/FIXED_OUTFILES
|
||||
.end literal
|
||||
.skip
|
||||
.indent -1
|
||||
2 /NAME_PREFIX
|
||||
.skip
|
||||
.literal
|
||||
/NAME_PREFIX=prefix
|
||||
.end literal
|
||||
.skip
|
||||
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.
|
||||
|
||||
.skip
|
||||
.indent -1
|
||||
2 /NOLINES
|
||||
.skip
|
||||
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.
|
||||
.skip
|
||||
.indent -1
|
||||
2 /NOPARSER
|
||||
.skip
|
||||
Do not generate the parser code into the output; generate only
|
||||
declarations. The generated name_tab.c file will have only
|
||||
constant declarations. In addition, a name.act file is
|
||||
generated containing a switch statement body containing all the
|
||||
translated actions.
|
||||
.skip
|
||||
.indent -1
|
||||
2 /OUTPUT
|
||||
.skip
|
||||
.literal
|
||||
/OUTPUT=outfile
|
||||
.end literal
|
||||
.skip
|
||||
Specify the name "outfile" for the parser file.
|
||||
.skip
|
||||
.indent -1
|
||||
2 /RAW
|
||||
.skip
|
||||
When this switch is specified, the .tab.h file defines the tokens to
|
||||
have the bison token numbers rather than the yacc compatible numbers.
|
||||
To employ this switch you would have to have your own parser.
|
||||
.skip
|
||||
.indent -1
|
||||
2 /TOKEN_TABLE
|
||||
.skip
|
||||
This switch causes the name_tab.c output to include a list of
|
||||
token names in order by their token numbers; this is defined in the array
|
||||
yytname. Also generated are #defines for YYNTOKENS, YYNNTS, YYNRULES,
|
||||
and YYNSTATES.
|
||||
|
||||
.skip
|
||||
.indent -1
|
||||
2 /VERBOSE
|
||||
.skip
|
||||
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.
|
||||
.skip
|
||||
This file also describes all the conflicts, both those resolved by
|
||||
operator precedence and the unresolved ones.
|
||||
.skip
|
||||
The file's name is made by removing _tab.c or .c from
|
||||
the parser output file name, and adding .output instead.
|
||||
.skip
|
||||
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.
|
||||
.skip
|
||||
.indent -1

Print the version number of Bison.

The command line syntax for Bison on @acronym{VMS} is a variant of the usual
|
||||
Bison command syntax---adapted to fit @acronym{VMS} conventions.
|
||||
|
||||
To find the @acronym{VMS} equivalent for any Bison option, start with the long
|
||||
option, and substitute a @samp{/} for the leading @samp{--}, and
|
||||
substitute a @samp{_} for each @samp{-} in the name of the long option.
|
||||
For example, the following invocation under @acronym{VMS}:
|
||||
|
||||
@example
|
||||
bison /debug/name_prefix=bar foo.y
|
||||
@end example
|
||||
|

@noindent
|

is equivalent to the following command under @acronym{POSIX}.

|

@example
|
||||
bison --debug --name-prefix=bar foo.y
|

@end example
|

|
||||
The @acronym{VMS} file system does not permit filenames such as
|
||||
@file{foo.tab.c}. In the above example, the output file
|
||||
would instead be named @file{foo_tab.c}.
