Tab completion doesn't work.

Tab completion doesn't work.

[-- Attachment #1: Type: text/plain, Size: 506 bytes --]

Hi here,

In my Emacs, I want to inspect the value of the variable
`bibtex-completion-cite-commands` defined by helm-bibtex package. But
what puzzles me is `C-h v bib RET` doesn't expand to any completions,
as shown in the attached screenshot.

Any tips for this problem?

Regards,
Zhao

Is the package correctly installed and loaded?

In my case, the configuration for helm and helm-bibtex is as follows:

```elisp
(use-package helm
  :bind (:map helm-command-map
          ("C-c h" . helm-execute-persistent-action)))

(use-package helm-bibtex
  :init
  (setq
   bibtex-completion-pdf-field "File"
   ;;https://github.com/tmalsburg/helm-bibtex#insert-latex-cite-commands
   bibtex-completion-cite-prompt-for-optional-arguments nil)

  :bind-keymap
  ("<menu>" . helm-command-prefix)
  :bind
  (
   :map helm-command-map
   ("b" . helm-bibtex)
   ("B" . helm-bibtex-with-local-bibliography)
   ("n" . helm-bibtex-with-notes)
   ("<menu>" . helm-resume)
   )

  :config
  (require 'helm-config)
  ;;https://github.com/tmalsburg/helm-bibtex#application-used-for-opening-pdfs
  ;;https://github.com/tmalsburg/helm-bibtex/issues/386
  (defun bibtex-completion-open-pdf-external (keys &optional fallback-action)
    (let ((bibtex-completion-pdf-open-function
       (lambda (fpath) (start-process "evince" "*helm-bibtex-evince*"
"/usr/bin/evince" fpath))))
      (bibtex-completion-open-pdf keys fallback-action)))

  (helm-bibtex-helmify-action bibtex-completion-open-pdf-external
helm-bibtex-open-pdf-external)

  (helm-add-action-to-source
   'helm-bibtex
   '(("P" helm-bibtex-open-pdf-external "Open PDF file in external
viewer (if present)")))

  ;;https://github.com/tmalsburg/helm-bibtex#browser-used-for-opening-urls-and-dois
  (setq bibtex-completion-browser-function
    (lambda (url _) (start-process "firefox" "*firefox*" "firefox" url)))

  )
```
I confirm the above configuration alone when testing with `emacs -Q`
doesn't trigger the problem here. So, it must be caused by other
settings.

See here [1] for the related discussion.

What does (featurep 'helm-bibtex) eval to?

C-x b *scratch* RET

Then in scratch buffer eval (featurep 'helm-bibtex) by C-x C-e gives nil.

Then the package is not loaded, your init file does not load it.  And the
variable is not known to Emacs.  Maybe there is an error on startup?

Then, I try to eval `(require 'helm-bibtex)` in scratch buffer and the
following error will be triggered:

AFAICT this file is not present in all helm installations (has it been
removed? I don't recall).

You are requiring that library in the config you posted.  I don't know
the background but I think I would try to simply remove that
requirement from your config.

The `(require 'helm-bibtex)` doesn't exist in my init.el, but just as
used to test the problem discussed here.

I mean "helm-config".  Or is the error above you posted not relevant?

Isn't (require 'helm-config) part of your config?

Thank you for pointing this out. I now have commented this line out in
my init.el, but still I cannot see the candidate
`bibtex-completion-cite-commands`, as shown in the attached
screenshot.

Then iterate: is the package loaded?  If not, do you get any other
error(s)?

eval `(featurep 'helm-bibtex)` still gives nil.

I tried to start as follows, but still did not see any error reports:

Then

(1) Does the *Messages* buffer maybe contain something useful after
startup?

(2) Does (require 'helm-bibtex) succeed without error?

So here is another error in the config you posted (the source argument
is missing in that call).

Unless I'm missing something, we found the problematic lines in your
config and you just have to specify the Helm source you want to add the
action to in the problematic expression I cited.

Yes. It solved the problem discussed here with the following configuration:

;;;;;;;;;;;;;;;;;;; begin config
;; https://github.com/emacs-helm/helm/wiki#if-installed-from-source
;; First issue the following command
/home/werner/.emacs.d/straight/repos/helm$ make
(use-package helm :config (require 'helm-autoloads))

(use-package helm-bibtex
  :init
  (setq
   bibtex-completion-pdf-field "File"
   ;;https://github.com/tmalsburg/helm-bibtex#insert-latex-cite-commands
   bibtex-completion-cite-prompt-for-optional-arguments nil)

And this also fixed the Tab completion problem discussed in this
thread, aka, `bib <Tab>` will give the desired completion, as shown in
the screenshot.

Ok - good!

I think you would benefit from enabling `debug-on-error' temporarily
when your init file is loaded, and/or, even better, start to compile
your init file regularly, since it will catch a lot of errors and
problems like this.

This will require some small changes (loading some stuff when compiling
etc.), but if you try to get rid of any warnings you will avoid most of
such surprises.

But I also noticed the following description here [1]:

Byte-compiling your init file is not recommended (see Byte Compilation
in the Emacs Lisp Reference Manual). It generally does not speed up
startup very much, and often leads to problems when you forget to
recompile the file. A better solution is to use the Emacs server to
reduce the number of times you have to start Emacs (see Using Emacs as
a Server). If your init file defines many functions, consider moving
them to a separate (byte-compiled) file that you load in your init
file.

Errors in your init file are worse.  Either simply remove the compiled
file afterwards or don't forget to recompile regularly.  You definitely
want some method to detect mistakes.
