In tty, the help window never closes

[yangchenyun]

The window will always be there no matter no matter what key I press.

I could provide more debug info if you point me to the right place to look at.

Show me the code of defhydra. Then explain how you get the bug in steps, from the Emacs start. I'm guessing you did emacs -nw, then info, then ...

[yangchenyun]

Hi Oleh, I did more test, it seems to only occur in a daemon/client mode. emacs --daemon & emacsclient -t

Then, bring up the `M-x info', try couple times with hydra then the window will become sticky.

(defhydra hydra-info (:color blue :hint nil :idle 0.4)

I can't reproduce this on Linux. If you have access to Linux, try to reproduce it there - it might be an OSX specific bug.

[yangchenyun]

I reproduced it on both linux / mac. I recorded a screen session: https://drive.google.com/file/d/0B3PWs5iiwLQjV3dFRHJhS0tSdmc/view?usp=sharing

[yangchenyun]

The sticky part is now a window (I cannot move cursor there), it seems just a "occupied" portion of the whole frame. New hydra dialog will open up a new window, see below (only the first half is interactive).

[yangchenyun]

I also tested on the emacs with GUI on ubuntu, the issue is the same and actually the some hydra definition doesn't even work. (like the snippet I copied from wiki, hydra-org-clock/body)

the Message buffer contains some error message from hydra:

hydra-disable: Invalid function: remove-function Composing main Info directory...done hydra-disable: Invalid function: remove-function

[yveszoundi]

I pretty much encounter the same issue. The menu remains sticky. Note: I only use emacs in the terminal, within tmux sessions, via emacsclient.

Screenshot

I'm calling a function to compose an email in org-mode via an hydra (later on org-mime-org-buffer-htmlize would be called within the buffer).

Environment

• Hydra : 0.13.4
• Emacs terminal: GNU Emacs 25.1.50.1
• Operating System: OSX El Capitan
• Other details: OSX Terminal, tmux

Relevant configuration

(define-key global-map (kbd "C-h M-o")
         (defhydra hydra-org-rimero (:color pink :hint nil)
        "
     ^Main^             ^Rimero^
     ^^^^^^^^------------------------------
     _c_: Capture       _n_: Notes
     _a_: Agenda        _b_: Bills
     _e_: Email         _i_: Inbox
     ^ ^                _A_: Accounting
     ^ ^                _l_: Links
     "
        ("c" org-capture)
        ("a" org-agenda)
        ("e" ers-org-email)
        ("n" (find-file org-ers-notes-file))
        ("b" (find-file org-ers-bills-file))
        ("i" (find-file org-ers-inbox-file))
        ("A" (find-file org-ers-accounting-file))
        ("l" (find-file org-ers-links-file))
        ("q" nil)))

Steps

• Call the relevant hydra binding that has a custom menu C-h M-o in my config
• Wait for the hydra popup menu to disappear

Expectations

• The hydra popup should vanish after invocation of a menu shortcut
• The above never happens, the menu just stays there

@yangchenyun , @abo-abo , it seems that adding :exit t to the hydra definition fixes it. @yangchenyun can you give it a shot?

Everything works as expected after updating my hydra definition to use :exit t.

@yveszoundi I was just about to reply, but you fould your issue. Swapping pink for teal would also work.

[yangchenyun]

@yveszoundi Thanks, I am giving it a shot and will verify it later.
