PlantUML has an "org-compatible" outlining mode to generate graphical tree images. It is ironically not org /babel/ compatible, since org does not like having lines starting with =*= in a source code block.
* Reproduction: ** Install instructions 1. Add config to your init. #+begin_src emacs-lisp (require 'plantuml-mode) ;Must install first. (plantuml-set-exec-mode "server") #+end_src ** Observe the bug Put your cursor in this block and run =org-babel-execute maybe=. It will not execute. #+begin_src plantuml :file "~/aphids-are-plant-bugs.png" @startmindmap * This is weird ** It does not work *** If you have bullet fonts on, they go all wonky. *** Org thinks this stuff inside is not plantuml. *** Cannot even do a src edit command. @endmindmap #+end_src -- Spenser Truex https://spensertruex.com/ San Francisco, USA
