- State "DONE"       from "NEXT"       [2020-10-01 Thu 21:28]
:END:

Frequent readers of this blog know that I'm in the process of
switching from [[id:tags-emacs][Emacs]] Org mode [[https://orgmode.org/worg/org-contrib/org-depend.html][org-depend]] to [[https://www.nongnu.org/org-edna-el/][org-edna]] because of the
additional functionality offered.

I had to convert [[id:2020-03-30-current-org-files][my existing Org files]] because both tools are using
the same =TRIGGER= and =BLOCKER= properties but with different syntax.
If the other syntax is found, syntax errors are reported since they
don't match.

Therefore, I wrote [[https://github.com/novoid/orgdepend_to_orgedna][orgdepend_to_orgedna]] which does the job of
converting Org files from org-depend to org-edna. Since I don't know
Elisp good enough, I wrote it in Python. However, I followed the [[https://en.wikipedia.org/wiki/Test-driven_development][TDD]]
approach and used [[http://mypy-lang.org/][static typing]] to ensure a good level of quality.

I used it to convert syntax of my personal use-cases with contains
only a limited set of org-depend syntax elements. However, in my
opinion, those use-cases reflect the most important use-cases for
org-depend so there is high chance that your files do not contain
non-recognized syntax to convert. Please do read the "Assumptions and
Notes" section of [[https://github.com/novoid/orgdepend_to_orgedna/blob/master/README.org][the readme file]].

I also included conversion of Elisp snippets which I'm using within my
[[https://github.com/Kungsgeten/yankpad][yankpad]] templates.

If you want to see the details of the migration capabilities, you have
to look at [[https://github.com/novoid/orgdepend_to_orgedna/blob/master/orgdepend_to_orgedna_test.py][the unit test file]].

If you're also using org-edna, you should check out [[https://github.com/toshism/org-linker-edna][org-linker-edna]]
which is a brand new thing that let's you define simple dependencies
with minimal effort.

Look at me, I've accomplished to write this blog article without
writing "org-elpa" as I've done several times in the recent weeks. ;-)
