* data/lalr1.java: Capture the declarations as m4 macros to avoid duplication. When push parsing, the declarations occur at the class instance level rather than within the parse() function. Change the way that the parser state is initialized. For push-parsing, the parse state declarations are moved to "push_parse_initialize()", which is called on the first invocation of "push_parse()". The %initial-action code is also inserted after the invocation of "push_parse_initialize()". The body of the parse loop is modified to return values at appropriate points when doing push parsing. In order to make push parsing work, it is necessary to divide YYNEWSTATE into two states: YYNEWSTATE and YYGETTOKEN. On the first call to push_parse(), the state is YYNEWSTATE. On all later entries, the state is set to YYGETTOKEN. The YYNEWSTATE switch arm falls through into YYGETTOKEN. YYGETTOKEN indicates that a new token is potentially needed. Normally, with a pull parser, this new token would be obtained by calling "yylex()". In the push parser, the value YYMORE is returned to the caller. On the next call to push_parse(), the parser will return to the YYGETTOKEN state and continue operation. * tests/javapush.at: New test file for java push parsing. * tests/testsuite.at: Use it. * tests/local.mk: Adjust. * doc/bison.texi (Java Push Parser Interface): New.

-*- outline -*- This directory contains data needed by Bison. * Skeletons Bison skeletons: the general shapes of the different parser kinds, that are specialized for specific grammars by the bison program. Currently, the supported skeletons are: - yacc.c It used to be named bison.simple: it corresponds to C Yacc compatible LALR(1) parsers. - lalr1.cc Produces a C++ parser class. - lalr1.java Produces a Java parser class. - glr.c A Generalized LR C parser based on Bison's LALR(1) tables. - glr.cc A Generalized LR C++ parser. Actually a C++ wrapper around glr.c. These skeletons are the only ones supported by the Bison team. Because the interface between skeletons and the bison program is not finished, *we are not bound to it*. In particular, Bison is not mature enough for us to consider that "foreign skeletons" are supported. * m4sugar This directory contains M4sugar, sort of an extended library for M4, which is used by Bison to instantiate the skeletons. * xslt This directory contains XSLT programs that transform Bison's XML output into various formats. - bison.xsl A library of routines used by the other XSLT programs. - xml2dot.xsl Conversion into GraphViz's dot format. - xml2text.xsl Conversion into text. - xml2xhtml.xsl Conversion into XHTML. ----- Copyright (C) 2002, 2008-2013 Free Software Foundation, Inc.
