Hi Viktor, Kyle

Fair enough. I’m not attached to the refine-function at all. If you like to have it removed, then remove it, unless others are of different opinion ofc. The functionality is fairly complex, so removing the keybinding might make it seem less complicated.

Hi Gustav,

currently, the remove functionality can also be accessed by C-u /. If we want to provide a dedicated hotkey, then the following definition will do it:

(add-hook 'org-agenda-mode-hook
          (lambda()
            (local-set-key (kbd "\") '(lambda()
                                        (interactive)
                                        (org-agenda-filter-by-tag nil nil 'exclude))))
          'append)

I would prefer to remove this function because it doesn’t add functionality. Keeping it around just adds another potential source of bugs.

Best,
Viktor

Hi Kyle, Viktor and the group,

I'd say it's a naming-problem. What, really, is the purpose of the function? Because applying the proposed change essentially makes the function identical to the function it calls. Right? And that function is still available for the user, so a "refinement" can be done without the org-agenda-filter-by-tag-refine (bound to backslash (\) ) function. As of now, using the function to exclude tags in the agenda provides a direct access to that functionality, instead of calling org-agenda-filter-by-tag (bound to slash (/) ) plus pushing the minus key (-) to switch from filter to exclude.

If you want to make any change, I'd suggest to instead change the name of org-agenda-filter-by-tag-refine to org-agenda-filter-by-tag-exclude and to leave the code within the function as is (well.. maybe change 'refine to 'exclude with the same argument as to the function name change).

Best Regards
Gustav

Hi Viktor,

Hi,

I noticed that org-agenda-filter-by-tag-refine started to exclude
selected tags by default recently because the 'refine in the call to
org-agenda-filter-by-tag is interpreted as an exclude flag.

This seems to have been introduced by 6c6ae99 (org-agenda: Filtering in the agenda on grouptags, 2015-01-24).


The attached patch fixes this.

However, it seems that the function is superfluous because
org-agenda-filter-by-tag can filter on multiple tags as well if called
multiple times (that used not to be the case earlier).  So maybe it
should be deprecated and removed?

I agree.  Gustav, does that make sense given your changes in 6c6ae99?
