Perhaps I'm confused, but I think org-babel-default-header-args:plantuml is actually an alist, right? I tried removing the (:results . "file") from org-babel-default-header-args:plantuml, and then overwriting the params argument inside the let* block like so: ``` (let* ((do-export (cdr (assq :file params))) (params (if do-export (add-to-list 'params '(:results . "file"))) (out-file ... ``` Logging the params variable after the let* block reveals that :results is set to "file", but I still get "Code block produced no output" when I try to evaluate the plantuml org src block. Thoughts? Joseph
