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.
