2008-10-08 Di-an Jan <dianj@freeshell.org> (tiny change)
Small but important bugfixes for the Java skeleton.
* data/lalr1.java (yyerror): Change Location to b4_location_type.
(yy_symbol_print): Call toString on yyvaluep.
* data/java.m4 (b4_single_class_if): Remove.
(b4_abstract_if): Look at "%define abstract".
(b4_lexer_if): New.
(b4_union_name): Rename...
(b4_yystype): ... to this. Map to "%define stype".
(b4_rhs_value, b4_parse_param_decl, b4_lex_param_decl,
b4_maybe_throws): Fix quoting.
(b4_lex_param_call): Move below to keep b4_*_param_decl close.
* data/lalr1.java (Lexer interface): Always define.
(Lexer interface within parser class): Remove.
(YYLexer class): New, used when "%code lexer" is present.
(constructor): When "%code lexer" is used, pass %lex-param
to the lexer constructor.
(yylex, yyparse): Remove %lex-param from method invocations
(YYStack, yyaction, yyparse): Rename b4_union_name to b4_yystype.
* doc/bison.texinfo (Java Bison Interface): Mention "%define
abstract". Rename "%define union_name" to "%define stype".
Rename method names according to previous patch.
(Java Scanner Interface): Describe "%code lexer" instead of
"%pure-parser" and "%define single_class".
(Java Differences): Mention "%code lexer".
* tests/java.at (_AT_DATA_JAVA_CALC_Y): Remove final argument.
Include scanner here, using macros from tests/local.at.
(AT_DATA_CALC_Y): Remove final argument.
(_AT_CHECK_JAVA_CALC): Likewise.
(AT_CHECK_JAVA_CALC): Likewise. Test all four combinations
of %locations and %error-verbose.
(main): Test with and without %lex-param.
* tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Push AT_LEXPARAM_IF.
(AT_BISON_OPTION_POPDEFS): Pop it.
* data/lalr1.java (Stack): Work around old verifiers that disallow
access to the private fields of an inner class, from the outer class.
We can make Stack's fields public because user code doesn't have access
to the instance of Stack used by parse().
* NEWS: Mention java.
* TODO: Remove things that are done.
* bootstrap.conf: Add javacomp-script and javaexec-script.
* configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
* data/Makefile.am: Add new files.
* data/java-skel.m4: New.
* data/java.m4: New.
* data/lalr1.java: New.
* doc/bison.texinfo: Put "A Complete C++ Example" under
C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
under Other Languages.
* src/getargs.c (valid_languages): Add Java.
* src/getargs.h (struct bison_language): Update size of string fields.
* tests/Makefile.am: Add java.at.
* tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
* tests/java.at: New.
* tests/testsuite.at: Include it.
