Re: ox-taskjuggler scenarios

[Tim Cross <theophilusx@gmail.com>]

Hi David,

it has been many years since I last used taskjuggler from within org. I
recall when I did I had a similar issue to yours e.g. some valid task
juggler values could not be passed into task juggler from within org
mode.

Although my recollections is hazy, I seem to recall that when I looked
at the code, the ox-taskjuiggler.el code only accepted a subset of what
was valid input for taskjuggler. I ended up doing something similar to
you i.e. generated the export file and then modify it before generating
the taskjuggler artifacts.

From memory, it looked like it would be fairly easy to modify the
taskjuggler elisp code to add additional support/integration, but my
requirements moved on and I stopped needing to use taskjuggler, so never
got around to it.

I do recall sending emails to the ox-taskjuggler.el author, but did not
get any response.

My guess is that ox-taskjuggler.el is currently lacking an active
maintainer. Bastien can probably clarify, but I would consider just
modifying the code to add the missing functionality you need and posting
some patches. Maybe someone can take on the maintenance, but until that
happens, I would consider ox-taskjuggler.el to be a basic starting point
which you can modify for your needs (it is part of the contrib packages
and not core org).
