.SH DESCRIPTION
.I Bison
is a parser generator in the style of
.BR \-\-file-prefix ,
connect the option name and the argument with
.BR = .
-.SS OPTIONS
+.PP
+Generate LALR(1) and GLR parsers.
+.PP
+Mandatory arguments to long options are mandatory for short options too.
+.SS "Operation modes:"
.TP
-.BI \-b " file-prefix"
-.br
-.ns
+\fB\-h\fR, \fB\-\-help\fR
+display this help and exit
.TP
-.BI \-\-file-prefix= file-prefix
-Specify a prefix to use for all
-.I bison
-output file names. The names are
-chosen as if the input file were named
-\fIfile-prefix\fP\fB.c\fP.
+\fB\-V\fR, \fB\-\-version\fR
+output version information and exit
.TP
-.B \-d
-.br
-.ns
-Write an extra output file containing macro definitions for the token
-type names defined in the grammar and the semantic value type
-.BR YYSTYPE ,
-as well as a few
-.B extern
-variable declarations.
-.sp
-If the parser output file is named
-.IB name .c
-then this file
-is named
-\fIname\fP\fB.h\fP.
-.sp
-This output file is essential if you wish to put the definition of
-.B yylex
-in a separate source file, because
-.B yylex
-needs to be able to refer to token type codes and the variable
-.BR yylval .
-.TP
-.BI \-\-defines= defines-file
-The behavior of
-.B \-\-defines
-is the same than
-.B \-d
-option.
-The only difference is that it has an optional argument which is
-the name of the output filename.
-.TP
-.BI \-g
-.br
-.ns
-Output a graph of the grammar automaton computed by
-Bison. If the grammar file is
-.BR foo.y
-, the output file will be
-.BR foo.dot .
-.TP
-.BI \-\-graph= graph-file
-The behavior of
-.BI \-\-graph
-is the same than
-.BI \-g
-option. The only difference is that it has an optional argument which
-is the name of the output graph filename.
-.TP
-.B \-k
-.br
-.ns
-.TP
-.B \-\-token-table
-This switch causes the
-.IB name .tab.c
-output to include a list of
-token names in order by their token numbers; this is defined in the array
-.IR yytname .
-Also generated
-are #defines for
-.IR YYNTOKENS ,
-.IR YYNNTS ,
-.IR YYNRULES ,
-and
-.IR YYNSTATES .
+\fB\-\-print\-localedir\fR
+output directory containing locale\-dependent data
.TP
-.B \-l
-.br
-.ns
+\fB\-\-print\-datadir\fR
+output directory containing skeletons and XSLT
.TP
-.B \-\-no-lines
-Don't put any
-.B #line
-preprocessor commands in the parser file.
-Ordinarily
-.I 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.
+\fB\-y\fR, \fB\-\-yacc\fR
+emulate POSIX Yacc
.TP
-.BI \-o " outfile"
-.br
-.ns
-.TP
-.BI \-\-output-file= outfile
-Specify the name
-.I outfile
-for the parser file.
-.sp
-The other output files' names are constructed from
-.I outfile
-as described under the
-.B \-v
-and
-.B \-d
-switches.
+\fB\-W\fR, \fB\-\-warnings\fR=\fI[CATEGORY]\fR
+report the warnings falling in CATEGORY
+.SS "Parser:"
.TP
-.BI \-p " prefix"
-.br
-.ns
+\fB\-S\fR, \fB\-\-skeleton\fR=\fIFILE\fR
+specify the skeleton to use
.TP
-.BI \-\-name-prefix= prefix
-Rename the external symbols used in the parser so that they start with
-.I prefix
-instead of
-.BR yy .
-The precise list of symbols renamed is
-.BR yyparse ,
-.BR yylex ,
-.BR yyerror ,
-.BR yylval ,
-.BR yychar ,
-and
-.BR yydebug .
-.sp
-For example, if you use
-.BR "\-p c" ,
-the names become
-.BR cparse ,
-.BR clex ,
-and so on.
-.TP
-.B \-t
-.br
-.ns
+\fB\-t\fR, \fB\-\-debug\fR
+instrument the parser for debugging
.TP
-.B \-\-debug
-In the parser file, define the macro
-.B YYDEBUG
-to 1 if it is not already defined,
-so that the debugging facilities are compiled.
+\fB\-\-locations\fR
+enable locations computation
.TP
-.B \-v
-.br
-.ns
-.TP
-.B \-\-verbose
-Write an extra output file containing verbose descriptions of the
-parser states and what is done for each type of lookahead token in
-that state.
-.sp
-This file also describes all the conflicts, both those resolved by
-operator precedence and the unresolved ones.
-.sp
-The file's name is made by removing
-.B .tab.c
-or
-.B .c
-from the parser output file name, and adding
-.B .output
-instead.
-.sp
-Therefore, if the input file is
-.BR foo.y ,
-then the parser file is called
-.B foo.tab.c
-by default. As a consequence, the verbose
-output file is called
-.BR foo.output .
-.TP
-.B \-V
-.br
-.ns
+\fB\-p\fR, \fB\-\-name\-prefix\fR=\fIPREFIX\fR
+prepend PREFIX to the external symbols
.TP
-.B \-\-version
-Print the version number of
-.I bison
-and exit.
+\fB\-l\fR, \fB\-\-no\-lines\fR
+don't generate `#line' directives
.TP
-.B \-h
-.br
-.ns
+\fB\-k\fR, \fB\-\-token\-table\fR
+include a table of token names
+.SS "Output:"
.TP
-.B \-\-help
-Print a summary of the options to
-.I bison
-and exit.
+\fB\-d\fR, \fB\-\-defines\fR[=\fIFILE\fR]
+also produce a header file
.TP
-.B \-y
-.br
-.ns
+\fB\-r\fR, \fB\-\-report\fR=\fITHINGS\fR
+also produce details on the automaton
.TP
-.B \-\-yacc
-.br
-.ns
-.TP
-.B \-\-fixed-output-files
-Equivalent to
-.BR "\-o y.tab.c" ;
-the parser output file is called
-.BR y.tab.c ,
-and the other outputs are called
-.B y.output
-and
-.BR y.tab.h .
-The purpose of this switch is to imitate
-.IR yacc 's
-output file name conventions.
-Thus, the following shell script can substitute for
-.I yacc
-and is often installed as
-.IR yacc :
-.sp
-.RS
-.ft B
-bison \-y "$@"
-.ft R
-.sp
-.RE
