From 364d710448e607e4ae9cb338583179dd6e734f0b Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Wed, 20 Nov 2019 16:39:44 -0700 Subject: [PATCH] Make isearch change readline prompt in TUI PR tui/23619 points out that isearch changes the prompt in the CLI gdb (and in Bash) -- but not in the TUI. This turns out to be easily fixed by removing tui_rl_saved_prompt and instead using the prompt that readline computes. This is stored in rl_display_prompt, which according to git was added in readline 6.2. gdb/ChangeLog 2019-12-20 Tom Tromey PR tui/23619: * tui/tui-io.c (tui_rl_saved_prompt): Remove. (tui_redisplay_readline): Use rl_display_prompt. (tui_prep_terminal): Update.
