From 089afdc8ccbd37647f3b9d3b6181db5bcf3e43e9 Mon Sep 17 00:00:00 2001 From: Chris Feng Date: Thu, 6 Oct 2016 12:47:56 +0800 Subject: [PATCH] Fix problems with active minibuffer * exwm-floating.el (exwm-floating--unset-floating): Never use the minibuffer window to display an `exwm-mode' buffer. * exwm-input.el (exwm-input--on-buffer-list-update) (exwm-input--update-focus): Allow updating input focus when the minibuffer is active. (exwm-input--update-focus): Handle the case when an auto-hiding minibuffer is active. (exwm-input--during-key-sequence): Renamed to `exwm-input--line-mode-passthrough'. (exwm-input--line-mode-passthrough): New variable for forcing all events to be passed to Emacs in line-mode. (exwm-input--on-KeyPress-line-mode, exwm-input-send-next-key): Use it. (exwm-input--finish-key-sequence, exwm-input--init, exwm-input--exit): Drop `exwm-input--finish-key-sequence'. (exwm-input--line-mode-cache): New variable for caching incomplete key sequences. (exwm-input--cache-event): New function for handling new key events. (exwm-input--on-KeyPress-line-mode, exwm-input--on-KeyPress-char-mode): Use it. --- exwm-floating.el | 6 ++-- exwm-input.el | 83 +++++++++++++++++++++++++----------------------- 2 files changed, 47 insertions(+), 42 deletions(-) diff --git a/exwm-floating.el b/exwm-floating.el index 1780e5fc3..dffdc3cd1 100644 --- a/exwm-floating.el +++ b/exwm-floating.el @@ -337,9 +337,11 @@ context of the corresponding buffer.")
