Hi! I use NixOS and ditaa is globally installed. That means I have ditaa executable in PATH but no easy way to find a ditaa.jar file. There is no way to instruct org-ditaa to use the specified executable (it requires java and path to the ditaa jar file). Note also that I don't have java in PATH.
I would like org-ditaa to use ditaa executable from the PATH. Same goes for org-plantuml. Regards, Alexey Shmalko
