Greetings Ihor.
Thanks for your feedback. A couple of notes and questions before I can proceed to format the next version of the patch.

Will do so.

This could be done, but I do not see much harm in providing an override. Note that the file extension is used by default. So, your choice: is it a) file extension only b) file extension with possibility to override with parameters? >> + (message cmd) >> + (shell-command cmd) >> + (when pdf >> + (let ((pdf-cmd (concat "epstopdf" " " ditaa-out-file " " >> + "-o=" (org-babel-process-file-name out-file)))) >> + (message pdf-cmd) > > Why message? I was originally directed to ob-plantuml, which message's its command. During the testing of this patch I found messaging useful to observe what was happening. So, your choice: a) no messaging b) message always c) defcustom a toggle for messaging? And, finally, should I add myself as the maintainer? All the best, Jarmo
