From 9d2d8a16e1ce033d6b7956d4b4f37961705bb5cf Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Wed, 13 Jan 2021 20:08:51 +0000 Subject: gdb: add new version style This commit adds a new 'version' style, which replaces the hard coded styling currently used for GDB's version string. GDB's version number is displayed: 1. In the output of 'show version', and 2. When GDB starts up (without the --quiet option). This new style can only ever affect the first of these two cases as the second case is printed before GDB has processed any initialization files, or processed any GDB commands passed on the command line. However, because the first case exists I think this commit makes sense, it means the style is no longer hard coded into GDB, and we can add some tests that the style can be enabled/disabled correctly. This commit is an alternative to a patch Tom posted here: https://sourceware.org/pipermail/gdb-patches/2020-June/169820.html I've used the style name 'version' instead of 'startup' to reflect what the style is actually used for. If other parts of the startup text end up being highlighted I imagine they would get their own styles based on what is being highlighted. I feel this is more inline with the other style names that are already in use within GDB. I also decoupled adding this style from the idea of startup options, and the possibility of auto-saving startup options. Those ideas can be explored in later patches. This commit should probably be considered only a partial solution to issue PR cli/25956. The colours of the style are no longer hard coded, however, it is still impossible to change the styling of the version string displayed during startup, so in one sense, the styling of that string is still "hard coded". A later patch will hopefully extend GDB to allow it to adjust the version styling before the initial version string is printed. gdb/ChangeLog: PR cli/25956 * cli/cli-style.c: Add 'cli/cli-setshow.h' include.
