Yacc - an LALR(1) parser generator for Java
byaccj [ -dlrtvJ ] [ -b prefix ] [-Jclass= classname ] [-Jpackage=
package_name ] [-Jextends= extends_name ] [-Jimplements=
implements_name ] [-Jsemantic= semantic_type ] [-Jnorun] [-Jnocontruct]
[-Jstack= NNN ] [-Jnodebug] [-Jfinal] [-Jthrows= exception_list ]
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:
The -b option changes the prefix prepended to the output
file names to the string denoted by prefix. The default
prefix is the character y.
-d The -d option causes the header file y.tab.h to be
-l If the -l option is not specified, yacc will insert The
generated code to the user's original code. If the -l
option is specified, yacc will not insert the .TP -r The
-r option causes 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 The -t option changes the preprocessor directives
generated by yacc so that debugging statements will be
incorporated in the compiled code.
-v The -v option causes a human-readable description of the
generated parser to be written to the file y.output.
-J The -J option switches from C/C++ to Java output. Not
necessary if other -J flags are used.
Changes the name of the Java class (and .java file) to
Changes the package in which the parser resides from the
default <nothing> to packagename
Changes the class the parser extends from the default
<nothing> to extend_name
Changes the interface the parser implements from the
default <nothing> to implement_name
Changes the semantic (value of the rules' variables)
type to semantic_type. No extra class will be generated.
The -Jnorun option informs Byacc to not generate a run()
method. Useful when working with threads.
The -Jnoconstruct option informs Byacc to not generate
constructors. Useful when extending classes.
Changes the stack size from default 500 to NNN
The -Jnodebug option informs Byacc to omit debugging code
for further better performance.
The -Jfinal option makes generated class final.
Informs Byacc to declare thrown exceptions for yyparse()
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
If there are rules that are never reduced, the number of such rules is
reported on standard error. If there are any LALR(1) conflicts, the
number of conflicts is reported on standard error.
