Let's clarify --help: use clearer "section" names, as in the doc.
Move --yacc to where it belongs.
* src/getargs.c (usage): Rename "Parser" as "Tuning the Parser", as in
the doc.
Rename "Output" as "Output Files"
Move --yacc to "Tuning the Parser".
* doc/bison.texi: Likewise.
It can now generate the usage message.
* src/complain.h (feature_fixit_parsable): Rename as...
(feature_fixit): this, for column economy.
Adjust dependencies.
(warning_usage): New.
Use it.
* src/complain.h, src/complain.c, src/getargs.h, src/getargs.c:
Use ARGMATCH_DEFINE_GROUP instead of the older interface.
The code is inconsistent: sometimes we pass by value, sometimes by
reference. Let's stick to the last, more conventional for large
values in C.
* src/scan-code.l: Pass locations by reference.
* configure.ac (DCFLAGS): Pass -g.
* data/skeletons/d.m4 (b4_locations_if): Remove, let bison.m4's one do
its job.
* data/skeletons/lalr1.d (position): Leave filename empty by default.
(position::toString): Don't print empty file names.
(location::this): New ctor.
(location::toString): Match the implementations of C/C++.
(yy_semantic_null): Leave undefined, the previous implementation does
not compile.
* tests/calc.at: Improve the implementation for D.
Enable more checks, in particular using locations.
* tests/local.at (AT_YYERROR_DEFINE(d)): Fix its implementation.
Sadly enough, AFAIK, there were never answers to the "More user
feedback will help to stabilize it" sentences. Remove them.
* src/getargs.c: IELR, canonical LR and XML output are here to stay,
and they are no more experimental than some other features.
* doc/bison.texi: Likewise.
Also remove "experimental" warning for Java, LAC, LR tuning options,
and named references.
* 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.
Travis answered favorably to my suggestion to provide a means to
disable git clone on some jobs (issue 7542). See
https://docs.travis-ci.com/user/customizing-the-build/#disabling-git-clone.
* .travis.yml: Disable git globally, enable it for i. the compile job,
and ii. the test job on ICC which needs the install-icc.sh script.
This is an experiment. Maybe more styles will be used (in which case
a short-hand function will be useful), maybe it will be just reverted.
* data/bison-default.css (.traces0): New.
* src/lalr.c (lalr): Use it.
See e3fdc37049: in C++ we generate
explicitly the code for the default action instead of simply copying
blindly the semantic value buffer. This is important when copying
raw memory is not enough, as exemplified by move-only types.
This is currently tested by examples/c++/variant.yy and variant-11.yy.
But it is safer to also have a test in the main test suite.
* tests/local.at (AT_REQUIRE_CXX_STD): Fix.
(AT_BISON_OPTION_PUSHDEFS, AT_BISON_OPTION_POPDEFS): Define/undefine
AT_BISON_OPTIONS.
* tests/c++.at (Default action): New.
It will be convenient to check sets elsewhere.
* tests/sets.at (AT_EXTRACT_SETS): Transform into...
* tests/local.at (AT_SETS_CHECK): this.
* tests/sets.at: Adjust.
The final gain is small: 2h2min instead 2h9min. But that is still an
improvement.
* .travis.yml (git.depth): Make the clone very shallow.
(git.submodules): Don't clone gnulib in test jobs.
(jobs.include.compile.script): Do it here.
