My first version property "EVAL" inline src block indeed don't using
:async and :session. It can play video file.
But I found it will block [Tab] org-cycle expand headline. I don't want
Emacs to be suspended. So I added :async change.
Now I use python `os.system()` to invoke shell command works fine.
Here is my current version:
(defcustom org-property-eval-keyword "EVAL"
"A property keyword for evaluate code."
:type 'string
:safe #'stringp
:group 'org)
(add-to-list 'org-default-properties org-property-eval-keyword)
(defun org-property-eval-on-cycle-expand (&optional state)
"Evaluate Org inline source block in property value on headline cycle expand."
(when (memq state '(children subtree))
(if-let ((inline-src-block (org-entry-get nil org-property-eval-keyword
nil)))
(with-temp-buffer
(insert inline-src-block)
(goto-char (point-min))
(let* ((context (org-element-context))
(lang (org-element-property :language context))
(type (org-element-type context))
(src-block-info (org-babel-get-src-block-info nil context)))
(when (eq type 'inline-src-block)
(org-babel-execute-src-block
nil src-block-info
(pcase lang
("sh" `((:session . ,(make-temp-name " *ob-sh-inline-async
(sh) ")) (:async . "yes") (:results . "silent")))
("shell" `((:session . ,(make-temp-name " *ob-sh-inline-async
(shell) ")) (:async . "yes") (:results . "silent")))
("bash" `((:session . ,(make-temp-name " *ob-sh-inline-async
(bash) ")) (:async . "yes") (:results . "silent")))
("zsh" `((:session . ,(make-temp-name " *ob-sh-inline-async
(zsh) ")) (:async . "yes") (:results . "silent")))
("python" `((:session . ,(make-temp-name
"ob-python-inline-async ")) (:async . "yes") (:results . "silent")))
(_ '((:results . "none")))))))))))
(add-hook 'org-cycle-hook #'org-property-eval-on-cycle-expand)
(defvar org-property-eval-templates
'("src_sh{mpg123 \"path/to/music.mp3\"}"
"src_python{import os; os.system(\"mpv 'path/to/video.mp4' \")}"))
(org-completing-read-property-construct-function "EVAL"
org-property-eval-templates)
(add-to-list 'org-property-set-functions-alist '("EVAL" .
org-completing-read-property_eval))
