Exporting org-mode's entries to html is a fantastic way for knowledge sharing!
Usually entries of "TODO" "HALF" "DELEGATE" "CANCELED" "DEFERRED" are incomplete/immature knowledge.
Thus, I don't want to export them. Furthermore, after they are marked as "DONE", I'd like to export them.
Any idea for how to do this?
Note that org-export-exclude-tags doesn't help us, at my first glance.
Draft solution:
After checking the implementation of org-mode for this part, I found org-export-handle-export-tags function.
It determines what to be excluded when exporting, by search regexp of :\\(TAG1\\|TAG2\\|...\\): in entries' title.
Thus I override org-export-handle-export-tags, by search regexp of \\(TAG1\\|TAG2\\|...\\) with leading/tailing colon removed.
It's ugly but it works.
So my open question is what's the better solution?
