From: Tom Tromey Date: Tue, 10 Sep 2019 23:25:35 +0000 (-0600) Subject: Give a name to the TUI SingleKey keymap X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=11061048d;p=binutils-gdb.git Give a name to the TUI SingleKey keymap Readline 8.0 has a feature that lets an application name a keymap. This in turn makes it simpler for users to bind keys in keymaps in their .inputrc. This patch gives a name to the TUI SingleKey keymap, so that additional bindings can be made there. For example: $if gdb set keymap SingleKey "X": "echo hello\\n\n" $endif The call to rl_initialize, in tui_initialize_readline, had to be removed so that .inputrc was not read too early. Note that Readline explicitly documents that this call is not needed. gdb/ChangeLog 2019-09-18 Tom Tromey * NEWS: Add entry. * tui/tui.c (tui_initialize_readline): Set name of keymap.
