.Sh DESCRIPTION
|
||||
.Nm Yacc
|
||||
reads the grammar specification in the file
|
||||
.I filename
|
||||
.Ar filename
|
||||
and generates an LR(1) parser for it.
|
||||
The parsers consist of a set of LALR(1) parsing tables and a driver routine
|
||||
written in the C programming language.
|
||||
.I Yacc
|
||||
.Nm Yacc
|
||||
normally writes the parse tables and the driver routine to the file
|
||||
.IR y.tab.c.
|
||||
.PP
|
||||
.Pa y.tab.c .
|
||||
.Pp
|
||||
The following options are available:
|
||||
.RS
|
||||
.TP
|
||||
\fB-b \fIfile_prefix\fR
|
||||
The
|
||||
.B -b
|
||||
option changes the prefix prepended to the output file names to
|
||||
.Bl -tag -width indent
|
||||
.It Fl b Ar file_prefix
|
||||
Change the prefix prepended to the output file names to
|
||||
the string denoted by
|
||||
.IR file_prefix.
|
||||
.Ar file_prefix .
|
||||
The default prefix is the character
|
||||
.IR y.
|
||||
.TP
|
||||
.B -d
|
||||
The \fB-d\fR option causes the header file
|
||||
.IR y.tab.h
|
||||
.Pa y .
|
||||
.It Fl d
|
||||
Cause the header file
|
||||
.Pa y.tab.h
|
||||
to be written.
|
||||
.TP
|
||||
.B -l
|
||||
.It Fl l
|
||||
If the
|
||||
.B -l
|
||||
.Fl l
|
||||
option is not specified,
|
||||
.I yacc
|
||||
.Nm
|
||||
will insert #line directives in the generated code.
|
||||
The #line directives let the C compiler relate errors in the
|
||||
generated code to the user's original code.
|
||||
If the \fB-l\fR option is specified,
|
||||
.I yacc
|
||||
If the
|
||||
.Fl l
|
||||
option is specified,
|
||||
.Nm
|
||||
will not insert the #line directives.
|
||||
Any #line directives specified by the user will be retained.
|
||||
.TP
|
||||
\fB-o \fIoutput_filename\fR
|
||||
The
|
||||
.B -o
|
||||
option causes
|
||||
.I yacc
|
||||
.It Fl o Ar output_filename
|
||||
Cause
|
||||
.Nm
|
||||
to write the generated code to
|
||||
.IR output_filename
|
||||
.Ar output_filename
|
||||
instead of the default file,
|
||||
.IR y.tab.c .
|
||||
.TP
|
||||
\fB-p \fIsymbol_prefix\fR
|
||||
The
|
||||
.B -p
|
||||
option changes the prefix prepended to yacc-generated symbols to
|
||||
.Pa y.tab.c .
|
||||
.It Fl p Ar symbol_prefix
|
||||
Change the prefix prepended to yacc-generated symbols to
|
||||
the string denoted by
|
||||
.IR symbol_prefix.
|
||||
.Ar symbol_prefix .
|
||||
The default prefix is the string
|
||||
.IR yy.
|
||||
.TP
|
||||
.B -r
|
||||
The
|
||||
.B -r
|
||||
option causes
|
||||
.I yacc
|
||||
.Pa yy .
|
||||
.It Fl r
|
||||
Cause
|
||||
.Nm
|
||||
to produce separate files for code and tables. The code file
|
||||
is named
|
||||
.IR y.code.c,
|
||||
.Pa y.code.c ,
|
||||
and the tables file is named
|
||||
.IR y.tab.c.
|
||||
.TP
|
||||
.B -t
|
||||
The
|
||||
.B -t
|
||||
option changes the preprocessor directives generated by
|
||||
.I yacc
|
||||
.Pa y.tab.c .
|
||||
.It Fl t
|
||||
Change the preprocessor directives generated by
|
||||
.Nm
|
||||
so that debugging statements will be incorporated in the compiled code.
|
||||
.TP
|
||||
.B -v
|
||||
The
|
||||
.B -v
|
||||
option causes a human-readable description of the generated parser to
|
||||
.It Fl v
|
||||
Cause a human-readable description of the generated parser to
|
||||
be written to the file
|
||||
.IR y.output.

If the environment variable TMPDIR is set, the string denoted by
