yacc [-dlrtv] [-b file_prefix] [-o output_filename] [-p symbol_prefix]
filename
DESCRIPTION
Yacc reads the grammar specification in the file 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. Yacc
normally writes the parse tables and the driver routine to the file
y.tab.c.
The following options are available:
-b file_prefix
Change the prefix prepended to the output file names to the
string denoted by file_prefix. The default prefix is the charac
ter y.
-d Cause the header file y.tab.h to be written.
-l If the -l option is not specified, yacc will insert #line direc
tives in the generated code. The #line directives let the C com
piler relate errors in the generated code to the user's original
code. If the -l option is specified, yacc will not insert the
#line directives. Any #line directives specified by the user
will be retained.
-o output_filename
Cause yacc to write the generated code to output_filename instead
of the default file, y.tab.c.
-p symbol_prefix
Change the prefix prepended to yacc-generated symbols to the
string denoted by symbol_prefix. The default prefix is the string
yy.
-r Cause yacc to produce separate files for code and tables. The
code file is named y.code.c, and the tables file is named
y.tab.c.
-t Change the preprocessor directives generated by yacc so that de
bugging statements will be incorporated in the compiled code.
-v Cause a human-readable description of the generated parser to be
written to the file y.output.
If the environment variable TMPDIR is set, the string denoted by TMPDIR
will be used as the name of the directory where the temporary files are
created.
