From 597bf39df91c9a2e27cf1966dd4c942ac645ae33 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 13 Jun 2019 00:06:52 +0100 Subject: [PATCH] Remove "show" command completers, "set" command completers for string commands The default command completer is symbol_completer, but it makes no sense for a "show" command to complete on symbols, or anything else, really. I wonder whether we should instead make the default be no completer. That seems like a much larger/complicated audit/change, so I'd like to move forward with this version, as it'll be covered by tests. I noticed this because a following patch will add a new gdb.base/settings.exp testcase that exercises all sorts of details of settings commands, including completing the show commands, using new representative "maint test-settings " commands. Also remove the completer for var_string and var_string_noescape commands. No point in completing symbols when GDB is expecting a string. gdb/ChangeLog: 2019-06-13 Pedro Alves * cli/cli-decode.c (add_setshow_cmd_full): Remove "show" completer.
