From: Andrew Burgess Date: Fri, 10 Jul 2015 13:06:28 +0000 (+0100) Subject: gdb/tui: Add command completion to winheight command. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=97605e61a14518b1a0ac2a576f4f3c843743e4d5;p=binutils-gdb.git gdb/tui: Add command completion to winheight command. Share the window name completion code from the focus command with the winheight command, providing window name completion for the winheight command. gdb/ChangeLog: * tui/tui-win.c (window_name_completer): New function. (focus_completer): Call window_name_completer. All old content moved into window_name_completer. (winheight_completer): New function. (_initialize_tui_win): Rename variable. Add completer to winheight command. Update doc string on winheight. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 5e687f0eafb..41400a20283 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,12 @@ +2015-07-13 Andrew Burgess + + * tui/tui-win.c (window_name_completer): New function. + (focus_completer): Call window_name_completer.
