In reading C++ diagnostics, it's often hard to find the name of the function in the middle of the template header, return type, parameters, and template arguments. So let's colorize it, and maybe the template argument bindings while we're at it. I've somewhat arbitrarily chosen bold green for the function name, and non-bold magenta for the template arguments. A side-effect of this is that when this happens in a quote (i.e. %qD), the rest of the quote after the function name is no longer bold. I think that's acceptable; returning to the bold would require maintaining a colorize stack instead of the on/off controls we have now. gcc/cp/ChangeLog: * error.cc (decl_to_string): Add show_color parameter. (subst_to_string): Likewise. (cp_printer): Pass it. (type_to_string): Set pp_show_color. (dump_function_name): Use "fnname" color. (dump_template_bindings): Use "targs" color. (struct colorize_guard): New. (reinit_cxx_pp): Clear pp_show_color. gcc/ChangeLog: * diagnostic-color.cc: Add fnname and targs color entries. * doc/invoke.texi: Document them. gcc/testsuite/ChangeLog: * g++.dg/diagnostic/function-color1.C: New test. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
