org-set-tags only allows completing a single tag

[elubeck]

Hello,

Org-set-tags differs slightly from the expected behavior of being able to autocomplete multiple tags for a headline. After autocompleting a single tag the minibuffer exits. If multiple tags are in my history they can be completed, but novel combinations of multiple tags are not autocompleted.

Thanks

Hi @elubeck ,

Sadly, this is a problem between org-mode and helm (see the discussion here).

A quick workaround is to disable helm completion for org-set-tags. It can be done by adding the following to your .spacemacs config:
(add-to-list 'helm-completing-read-handlers-alist '(org-set-tags)) (EDIT: wrong, see my next comment)
You will then have the "classic" completion for org tags, that works as expected.

Not sure if it would be relevant to add this to the org layer by default...

I just noticed that directly adding (add-to-list 'helm-completing-read-handlers-alist '(org-set-tags)) to the spacemacs config does not actually work. Spacemacs complains on startup that the helm-completing-read-handlers-alist variable does not exists (not sure why as the helm loading is delayed).
EDIT: anyways, at this point the org-set-tags is not loaded (org-mode is lazily loaded), so it would have failed even in this case

Instead I added the following to my user config:

(add-hook 'org-mode-hook
            (lambda () (add-to-list 'helm-completing-read-handlers-alist '(org-set-tags))))

that correctly sets the variable when launching org-mode.

2020 EDIT: Note that org-set-tags has since been renamed to org-set-tags-command, so to fix the behavior the correct config is now

(add-hook 'org-mode-hook
            (lambda () (add-to-list 'helm-completing-read-handlers-alist '(org-set-tags-command))))

It doesn't seem to be possible to completely remove tags with the helm interface either. After testing the native function I'd vote to change the default to not use helm until the issues are fixed.

I can still reproduce this behaviour in develop (95422ae).

As described in emacs-helm/helm#2063, it seems like the issue is on our side :(

When editing org tags (org-set-tags) with helm-mode enabled.

The tags can be removed by pressing C-RET or M-RET which calls helm-cr-empty-string.

The keys are visible on the mode line, when not using Spacemacs or any mode line packages

In Spacemacs

The keys are not visible with the mode line themes:

• spacemacs (default) (https://github.com/TheBB/spaceline)

• or doom (https://github.com/seagle0128/doom-modeline)

But the keys are visible with the vanilla mode line theme:

Thanks @duianto this resolved a long-standing inconvenience for me. Is there a way to include this keybinding in the spacemacs mode-line? I'd be willing to submit the relevant patch with a little guidance
