From: David Malcolm Date: Fri, 26 Aug 2016 17:59:08 +0000 (+0000) Subject: Tweak to colors of fix-it hints X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d41e76cf758505ba1bc22ca88cf6d1f626298def;p=gcc.git Tweak to colors of fix-it hints Previous, fix-it hints were printed using the color of the severity of the diagnostic (magenta for warnings, red for errors, cyan for notes). This patch updates fix-it hints so that replacement text is printed in green, to better distinguish the suggested improvement from the current code. For example: spellcheck-fields.cc:52:13: error: 'struct s' has no member named 'colour'; did you mean 'color'? return ptr->colour; <<< RED ^~~~~~ <<< RED color <<< GREEN It makes sense for the underlinings that indicate deletions to be printed in red, so the patch changes that also. For example: diagnostic-test-show-locus-color.c:179:9: warning: example of a removal hint int a;; <<< MAGENTA ^ <<< MAGENTA - <<< RED gcc/ChangeLog: * diagnostic-color.c (color_dict): Add "fixit-insert" and "fixit-delete". (parse_gcc_colors): Update description of default GCC_COLORS. * diagnostic-show-locus.c (colorizer::set_fixit_hint): Delete. (colorizer::set_fixit_insert): New method. (colorizer::set_fixit_delete): New method. (colorizer::get_color_by_name): New method. (colorizer::STATE_FIXIT_INSERT): New constant. (colorizer::STATE_FIXIT_DELETE): New constant. (class colorizer): Drop "_cs" suffix from fields. Delete "_ce" fields in favor of new field "m_stop_color". Add fields "m_fixit_insert" and "m_fixit_delete". (colorizer::colorizer): Update for above changes. Replace colorize_start calls with calls to get_color_by_name. (colorizer::begin_state): Handle STATE_FIXIT_INSERT and STATE_FIXIT_DELETE. Update for field renamings. (colorizer::finish_state): Simplify by using m_stop_color, rather than multiple identical "*_ce" fields. (colorizer::get_color_by_name): New method. (layout::print_any_fixits): Print insertions and replacements using the "fixit-insert" color, and deletions using the "fixit-delete" color. * doc/invoke.texi (-fdiagnostics-color): Update description of default GCC_COLORS, and of the supported capabilities. gcc/testsuite/ChangeLog: * gcc.dg/plugin/diagnostic-test-show-locus-color.c (test_fixit_insert): Update expected output. (test_fixit_remove): Likewise. (test_fixit_replace): Likewise.
