Akim Demaille	7ea108fa67	traces: use colors for the semantic values ... This makes reading the trace slightly easier. It would be very nice to highlight the "big steps", especially reductions. But this is a private experiment: do not use it. * data/diagnostics.css (value): New. * src/parse-gram.y: Use no delimiters and no c quotation for strings to facilitate debugging. (tron, troff, TRACE): New. Not very elegant, but until there is support for printf-formats in libtextstyle, it shall be enough.	2019-04-27 18:27:04 +02:00
Akim Demaille	4d34b06fb3	diagnostics: use gnulib's libtextstyle-optional ... Bruno Haible just added a default implementation of libtextstyle's interface when the library is not available. https://lists.gnu.org/archive/html/bison-patches/2019-03/msg00025.html * gnulib: Update. * bootstrap.conf: Replace libtextstyle with libtextstyle-optional. * src/complain.c, src/getargs.c: Remove now useless cpp guards.	2019-03-24 18:40:46 +01:00
Akim Demaille	f6e38d7ac9	diagnostics: use libtextstyle for colored output ... Bruno Haible released libtextstyle, a library for colored output based on CSS. Let's use it to generate colored diagnostics, provided libtextstyle is available. See https://lists.gnu.org/archive/html/bug-gnulib/2019-01/msg00176.html https://lists.gnu.org/archive/html/bison-patches/2019-02/msg00073.html https://lists.gnu.org/archive/html/bison-patches/2019-02/msg00084.html https://lists.gnu.org/archive/html/bison-patches/2019-03/msg00007.html * bootstrap.conf (gnulib_modules): Use libtextstyle when possible. * data/diagnostics.css: New. * src/complain.c (begin_use_class, end_use_class, flush) (severity_style, complain_init_color): New. Use them. * src/getargs.c (getargs_colors): New. (getargs): Use it. Skip --color and --style. * src/location.h, src/location.c (location_print): Use a style. * tests/bison.in: Force --color=yes when stderr is a tty. * tests/local.at: Disable colors during the test suite. * tests/input.at: Adjust expectations to the extra options passed on the command line.	2019-03-16 16:46:17 +01:00
