Cannot show sidebar

[manufactory]

Hello,

Calling frame-purpose-show-sidebar gives me the error message:

frame-purpose-show-sidebar: No clause matching ‘nil’

I just reproduced this with emacs -Q and only frame-purpose loaded in the following steps:

1. Enter in *scratch*, call M-x frame-purpose-mode and eval the example from the readme

   (frame-purpose-make-frame :modes 'org-mode
                         :title "Org")

2. Create two new buffers; /tmp/foo.org and /tmp/foo.bar

3. Call frame-purpose-show-sidebar

I'm running

• the latest package from MELPA (version 20190114.1403)
• GNU Emacs 27.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.22, cairo version 1.17.3) of 2020-08-28

Thanks for reporting.

Please let me know if that fixes it for you.

Thanks for working on this so quickly! When I start a fresh emacs instance (using -Q again), create two .org files and call M-x frame-purpose-show-sidebar, I get a sidebar, however it shows not only the Org-buffers:

*Minibuf-0*
*frame-purpose-buffers for frame: Org*
bar.org
foo.org
 *Echo Area 1*
*scratch*
 *Echo Area 0*
 *Minibuf-1*
*Completions*
init.el
*Messages*
 *code-conversion-work*

When I then close the sidebar using C-x C-k and call M-x frame-purpose-show-sidebar again, no sidebar but an error message is shown: frame-purpose-show-sidebar: Symbol’s function definition is void: nil.

I also noticed that the frame-purpose-make-frame returns a frame now, before the recent changes it returned nil

Thanks.
