I don't plan to fix everything in one go. But this was in the way of
the next commit.
* data/skeletons/lalr1.java: Avoid space before parens.
* tests/java.at: Adjust.
Soon calculator tests for Java will move from java.at to calc.at.
Which implies improving the Java testing infrastructure in
local.at (for instance really tracking columns in positions, not just
token number). Detach java.at from local.at.
* tests/java.at (AT_JAVA_POSITION_DEFINE_OLD): New.
Use it.
* data/skeletons/lalr1.java: Use more conventional function names for
Java.
Prefer < and <= to => and >.
Use the same approach for m4 quotation as in the other skeletons.
Fix indentation issues.
* tests/calc.at, tests/java.at, tests/javapush.at: Fix quotation style.
(main): Use 'args', not 'argv', the former seems more conventional and
is used elsewhere in Bison.
Prefer character literals to integers to denote characters.
* examples/java/Calc.y: Likewise.
The previous name was historical and inconsistent.
* src/muscle-tab.c (define_directive): Use the proper value passing
syntax, based on the muscle kind.
(muscle_percent_variable_update): Use the right value passing syntax.
Migrate from parser_class_name to api.parser.class.
* data/skeletons: Migrate from parser_class_name to api.parser.class.
* doc/bison.texi (%define Summary): Document both parser_class_name
and api.parser.class.
Promote the latter over the former.
* 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.
