FEATURE REQUEST: Tags column (formatter) for dynamic block

[ujikol]

This would be very simple and is an obviously missing feature.

It should be possible to filter the tags with regexp.

I fixed it for me with the following el-patch for (org-dblock-write:org-ql):

                   (el-patch-add
                     (cons 'tags (lambda (element &optional pattern)
                                   (s-join " "
                                           (--filter
                                            (or (not pattern)
                                                (s-matches? pattern it))
                                            (org-element-property :tags element))))))

As stated in my other feature request, tags and property columns should be able to access inherited tags/properties. This information is currently not accessible via the element parameter of (org-dblock-write:org-ql).
