* src/counterexample.c, src/parse-simulation.c: It is more usual in
Bison to use sizeof on expressions than on types, especially for
allocation.
Let the compiler do it's job instead of calling memcpy ourselves.
There are too many gl_list_t in there, it's hard to understand what is
going on. Introduce and use more precise types. I sure can be wrong
in some places, it's hard to tell without proper tool support.
* src/counterexample.c, src/lssi.c, src/lssi.h, src/parse-simulation.c,
* src/parse-simulation.h, src/state-item.c, src/state-item.h
(si_bfs_node_list, search_state_list, ssb_list, lssi_list)
(state_item_list): New.
It does not make a lot of sense to use ::= in our counterexamples,
that's not something that belongs to the Bison "vocabulary". Using
the colon makes sense, but it's too discreet. Let's use the arrow,
which we already use in some reports (HTML and Dot).
* src/gram.h (print_dot_fallback): Generalize into...
(print_fallback): this.
(print_arrow): New.
* src/derivation.c: Use it.
* NEWS, tests/conflicts.at, tests/counterexample.at,
* tests/diagnostics.at, tests/report.at: Adjust.
* doc/bison.texi: Ditto.
Unfortunately the literal `→` is output as `↦`. So we need to use
@arrow.
Prefer `&foos[i]` to `foos + i` when `foos` is an array. IMHO, it
makes the semantics clearer.
* src/counterexample.c, src/lssi.c, src/parse-simulation.c,
* src/state-item.c: With arrays, prefer the array notation rather than
the pointer one.
* examples/c/bistromathic/parse.y (user_context): We need the current
line.
(yyreport_syntax_error): Quote the guilty line, with squiggles.
* examples/c/bistromathic/bistromathic.test: Adjust.
Currently autocompletion on a line with errors leaks the error
messages. It can be useful to let the user know, but GNU Readline
does not provide us with an nice way to display the error. So we
actually break into the current line of the user.
So instead, do not show these errors.
* examples/c/bistromathic/parse.y (user_context): New.
Use %param to pass it to the parser and scanner.
Keep quiet when in computing autocompletion.
That quite defeats the whole point of locations... But anyway, we
should not see these messages at all.
* examples/c/bistromathic/parse.y (expected_tokens): Fix (useless)
location tracking.
Currently when we output useless rules, they appear before the
grammar, but using the same invocation. As a result, the anchor is
defined twice, and the wrong one, being first, is honored.
* data/xslt/xml2xhtml.xsl (rule): Take a new 'anchor' parameter to
decide whether being an anchor, or a target.
Let it be true when output the grammar.
* tests/report.at: Adjust.
The text and Dot reports are expected to be identical when generated
directly (--report, --graph) or indirectly (via XML). The xml
testsuite had not be run for ages, let it catch up a bit.
* src/print-xml.c: Pass the type of the symbols.
* data/xslt/xml2text.xsl
Catch up with the new layout.
Display the symbol types.
Use '•', not '.'
* tests/local.at: Smash '•' to '.' when matching against the direct
text report.
* tests/report.at: Adjust XML expectations.
* data/skeletons/c++.m4, data/skeletons/glr.c, data/skeletons/lalr1.d,
* data/skeletons/lalr1.java, data/skeletons/yacc.c:
Be more accurate about yychar and yytoken.
Don't name local variables as if they were members.
* examples/c/bistromathic/parse.y, examples/c/lexcalc/parse.y,
* examples/c/reccalc/parse.y: here.
Add some comments.
* src/parse-gram.y (api_version): Pull out of handle_require.
Bump to 3.7.
* data/bison-default.css: Cobalt does not seem to be supported.
* doc/bison.texi (Counterexamples): A new section.
(Understanding): Show the counterexamples as it shows in the report:
with its items.
(Bison Options): Document -Wcex and -rcex.
In commit c80cdf2db2 ("doc: simplify
uses of @ref", Jan 27 2020, released in Bison 3.6), I broke the
references to the Bibliography. For instance:
For a more detailed exposition of the mysterious behavior in LALR parsers
-and the benefits of IELR, @pxref{Bibliography,,Denny 2008 March}, and
-@ref{Bibliography,,Denny 2010 November}.
+and the benefits of IELR, @pxref{Bibliography}, and
+@ref{Bibliography}.
which results in "see Bibliography" twice, instead of the more precise
reference.
* doc/bison.texi (@pcite, @tcite): New.
Use them instead of @ref to Bibliography.
Cite only the first author (that's what we did for the other entries).
