jay - an LALR(1) parser generator for Java and C#


jay [ -tv ] [ -c ] [ -p ] [ -b file_prefix ] [ -V yyValue ] filename < skeleton


Jay 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 from the file skeleton written in the Java programming language. Jay writes the parse tables and the driver routine to standard output.

The following options are available:

-b file_prefix
The -b option changes the prefix prepended to the output file names to the string denoted by file_prefix. The default prefix is the character y.
The -c option makes jay generate C# code instead of the default Java.
The -t option arranges for debugging information to be incorporated in the compiled code.
The -v option causes a human-readable description of the generated parser to be written to the file y.output.
The -p option causes jay to print the directory in which its sample skeleton files are installed. If a project wants to use the default skeleton file included with jay, it can use this option in a makefile to find the path to the skeleton or skeleton.cs file included with the jay distribution.

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.




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.


Jay is derived from Berkeley yacc . Input conventions closely follow those of yacc ; for details, consult the parser skeleton file and the commented example included with the sources.
Je projette par la suite, de recompiler MultideskOS pour Amiga 500 et
Atari 1040 ST fm et STE. De cette manière, MultideskOS tournera sur
quelques plateformes et quelques plates formes tourneront sous celui-ci.
Ca marchera dans tous les sens :-)
