This change was made by applying emacs' untabify function to
nearly all files in Bison's repository. Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.
that the argument is case-insensitive, and there's no `=' here.
For the %skeleton entry, mention that %language is better.
(Bison Options): Likewise for --language and --skeleton. Move the
--skeleton entry so that the `Tuning the parser' section is sorted
alphabetically on long options.
(C++ Bison Interface): Don't use the word skeleton. Don't explain the
%language directive in detail here; cross-reference the %language
documentation instead.
(Calc++ Parser): Use `%require "@value{VERSION}"' rather than
`%require "2.3b"' so that the example is always up-to-date.
(Bison Symbols): Add entries for %language and %skeleton.
* examples/extexi (normalize): Instead of replacing every %require
argument with the current Bison version, just substitute for
`@value{VERSION}'. This guarantees that we're testing what actually
appears in the documentation.
* examples/calc++/Makefile.am ($(calc_extracted)): Use `$(VERSION)'
rather than `@VERSION@'.
Move the token type and YYSTYPE in the parser class.
* data/lalr1.cc (stack.hh, location.hh): Include earlier.
(parser::token): New, from the moved free definition of tokens.
(parser::semantic_value): Now a full definition instead of an
indirection to YYSTYPE.
(b4_post_prologue): No longer included in the header file, but
in the implementation file.
* doc/bison.texi (C+ Language Interface): Update.
* src/parse-gram.y: Support unary %define.
* tests/actions.at: Define global_tokens_and_yystype for backward
compatibility until we update the tests.
* tests/calc.at: Idem.
(first_line, first_column, last_line, last_column): Define for lalr1.cc
to simplify the code.
* examples/calc++/calc++-scanner.ll, examples/calc++/calc++.cc:
Remove from CVS. These files are automatically generated.
* examples/extexi: Clarify that this file is now part of Bison,
not GNU M4, and that it works with any POSIX-compatible Awk.
* examples/calc++/Makefile.am (run_extexi): Remove; not used.
($(calc_extracted)): Renamed from $(calc_sources_extracted),
so that we also get calc++-parser.yy. Geneate it.
Use $(AWK), not gawk, since any conforming Awk will do.
Put comment before action, since older 'make' can't handle comment
in action.
$(BUILT_SOURCES): List all built sources, not just some of them.
$(MAINTAINERCLEANFILES): Remove *.stamp, and all built sources.
$($(srcdir)/calc++-parser.stamp): Work even if POSIXLY_CORRECT.
$($(calc_sources_generated)): Remove unnecessary test for existence
of target. (This had a shell syntax error anyway; a stray "x".)
(calc_extracted): List $(srcdir)/calc++-parser.yy, not
calc++-parser.yy.
* examples/.cvsignore, examples/calc++/.cvsignore: New files.
* doc/bison.texinfo (Calc++): Add the extraction marks.
* examples/extexi: New, from the aborted GNU Programming 2E.
Separate the different paragraph of a file with empty lines.
* examples/Makefile: Use it to extract the whole calc++ example.
