`M-x help-with-tutorial-spec-language` will always get error message

Indeed, I can reproduce this from helm.sh and just doing M-x help-with-tutorial-spec-language.

OTOH, with my own settings, it seems to work (no error), although I get two completions buffers, one from helm, and one from vanilla completion.

[redguardtoo]

I'm using console emacs in shell, btw.

What are you reproducing ? Which error ? I still can't reproduce, please backtrace.

OTOH, with my own settings, it seems to work (no error), although I get two completions buffers, one from helm, and one from vanilla completion.

This is what I have from ./emacs-helm.sh and from my own emacs.

This is an emacs bug in `help-with-tutorial' which use redundant code:

(minibuffer-with-setup-hook #'minibuffer-completion-help (read-language-name 'tutorial "Language: " "English"))

only

(read-language-name 'tutorial "Language: " "English")

is needed.

I did some investigation, looks it's completing-read will always use the helm one instead original one even with my set up:

Here is the code copied from /usr/share/emacs/24.3/lisp/international/mule-cmds.el

(defun read-language-name (key prompt &optional default)
  "Read a language environment name which has information for KEY.
If KEY is nil, read any language environment.
Prompt with PROMPT.  DEFAULT is the default choice of language environment.
This returns a language environment name as a string."
  (let* ((completion-ignore-case t)
     (name (completing-read prompt
                language-info-alist
                (and key
                     (function (lambda (elm) (and (listp elm) (assq key elm)))))
                t nil nil default)))
    (if (and (> (length name) 0)
         (or (not key)
         (get-language-info name key)))
    name)))

My last message has not been posted, probably because the backtrace included so much words in different languages.

Thierry, I do indeed get an error, but I even get it with emacs -Q, i.e., without helm.

OTOH I do think that the redundant call

(minibuffer-with-setup-hook #'minibuffer-completion-help ...)

is intended, to help newbies, because they might not yet know how to complete before having read the tutorial.

@redguardtoo can you please test if you get the error even when turning off helm-mode, e.g. with emacs -Q?

Anyway, I do get an error with vanilla Emacs, so I'll make a bug report.

I have no error with emacs -Q, it is working as expected.

Before reporting it, I've updated my Emacs, just to be sure. The problem disappeared!

@redguardtoo: please try updating your Emacs if possible

@thierryvolpiatto: So there doesn't seem to be a problem with Helm. Maybe we can avoid that two completions buffer pop up, the helm completions plus the vanilla completions buffer?

Have you upgraded? If yes, do you still see the error with helm-mode enabled?

BTW, it's normal that helm substitutes `completing-read' (in all situations) - that's what helm-mode is for.

[redguardtoo]

yes, check my setup. i disable helm for certain command, but not work. that is the issue On Mar 15, 2014 12:15 AM, "michael-heerdegen" notifications@github.com wrote:

I think we should live with this.

To fix this we have to remove minibuffer-completion-help' from minibuffer-setup-hook'. It is what I do in helm--completing-read-default' and it is working in most cases, but when the hook is added withminibuffer-with-setup-hook' we have a closure and it is impossible to know what this closure is for. (i.e is this closure running minibuffer-completion-help ?)

I can remove all closures and keep only symbols, but we will loose useful closures that have been added here.

That doesn't sound good... Ok, then it's probably better to do nothing.

Ok, sorry for being inattentive, I think I understand now. Although you have

(help-with-tutorial-spec-language . nil)

in your setup, you nonetheless get an error when using helm-mode, but you don't get an error with emacs -Q. That's indeed a helm related problem.

But I can't reproduce it, also not with my Emacs 24.3.1 from the Debian repositories. Strange that I got an error in my trunk built before upgrading. BTW, the backtrace ended like this:

Debugger entered--Lisp error: (wrong-type-argument numberp nil) zerop(nil) minibuffer-completion-help()

Dunno which circumstances trigger this.

OK, looks solved if If I add to list helm-completing-read-handlers-alist with (help-with-tutorial . ido) but (help-with-tutorial) has the same error.

anyway, I'm fine with current solution.

Note you never told me what was this "same error", please send a backtrace starting from ./emacs-helm.sh (or the default setting of `helm-completing-read-handlers-alist').

This is an error message coming from delete-other-windows', if you turn ondebug-on-error', you will have a backtrace.

you mean "M-x toggle-debug-on-error", right? I always turn on it before reporting the bug. the weird thing is "can't expand minibuffer to full frame" is the only error message I got.

I actually edit the emacs's original lisp code, insert log function and try to debug it line by line before reporting the issue.

All I can tell is that in read-language-name the line containing completing-read my trigger the error.

to reproduce the bug, you need below code:

(setq helm-completing-read-handlers-alist
      '((describe-function . ido)
        (describe-variable . ido)
        (debug-on-entry . helm-completing-read-symbols)
        (find-function . helm-completing-read-symbols)
        (find-tag . helm-completing-read-with-cands-in-buffer)

        (wg-load . ido)
        (rgrep . ido)
        (read-directory-name . ido)
        ))

The only setup line related to this issue is (help-with-tutorial . nil)

My guess is that the error is caught by a condition-case'. You can nonehteless get a backtrace by setting the variabledebug-on-message' to a regexp matching the message you get:

(setq debug-on-message "can't expand minibuffer to full frame")

Note that when the debugger pops up, the error has already been caught, so this backtrace will only reveal where the error happens, but won't show the cause of the error, so we will need to dig further then.

to reproduce the bug, you need below code:

Sorry, i can't reproduce it. Maybe this depends on circumstances outside of Emacs.

Thanks, Michael.

Nothing in backtrace. Here is the info from message buffer.

What does "nothing in backtrace" mean? I see that the debugger popped up. Please post the contents of the backtrace buffer. Or was it completely empty???

Oh no!

Ok, I grepped the Emacs sources for

"Can't expand minibuffer to full frame"

and there is only one match: in delete-other-windows in window.el. So, please try M-x debug-on-entry delete-other-windows RET. Hopefully you get a useful backtrace this time. Please load the relevant source files before (window.el, helm sources) so that we get a backtrace without unreadable byte code.

Now I know, it's because I'm using popwin and helm will call its API.

and looks my popwin set up has some issue:

(require 'popwin)

(setq popwin:special-display-config nil)
(setq display-buffer-function 'popwin:display-buffer)

;; enable popwin-mode globally is too dangerous

Ok, thanks. Looks quite like a bug in popwin. I don't use popwin, but I guess when you are using helm, you can just remove

(add-to-list 'popwin:special-display-config '("*Completions*" :noselect t))

from you config, which seems to trigger the bug, and is not needed with helm-mode turned on.

If you have used a minimal emacs settings (emacs -Q) or the script ./emacs-helm.sh as preconised, you would have saved our time...
