Import files to babel blocks

Import files to babel blocks

[Michael Bach]

Dear org-mode Users and Developers,

I am trying to write a simple function for importing files to org-mode
babel code blocks.

My naive approach was

--8<---------------cut here---------------start------------->8---
(defun import-to-org-from-files (path pattern progmode)
  (mapcar #'(lambda (filepath)
              (progn
                (insert (format
                         "\n#+name: %s\n" (file-name-nondirectory
                                           (file-name-sans-extension
                                            filepath))))
                (insert (format "#+begin_src: %s :eval no\n" progmode))
                (insert-file-contents filepath)
                (insert "\n#+end_src\n"))
              )
          (directory-files path t pattern)))
--8<---------------cut here---------------end--------------->8---

to be called e.g. like this

--8<---------------cut here---------------start------------->8---
(import-to-org-from-files "/path/to/scripts/" ".*\.sh$" "sh")
--8<---------------cut here---------------end--------------->8---


This leads to all babel code blocks being inserted empty and all file
content inserted afterwards, i.e. the `insert-file-contents' is somehow
delayed until all `insert's have happened.

Maybe this is just related to my misunderstanding of the involved elisp,
but I am posting it here since I am sure someone must have thought about
this import. Or is there even an org-mode builtin that can be used?

Best Regards,
Michael

From the documentation (C-h f insert-file-contents), it says that it
"returns list of absolute file name and number of characters" but
doesn't move the marker forwards, unlike insert does.  So, I guess you
would have to then move the marker forwards by the number of characters.

Erhm, another case of readthedocs... Thanks for the shove! For
reference, I got it to work using a simple let like so:

--8<---------------cut here---------------start------------->8---
(defun import-to-org-from-files (path pattern progmode)
    (mapcar #'(lambda (filepath)
                (progn
                  (insert (format
                           "\n#+name: %s\n" (file-name-nondirectory
                                             (file-name-sans-extension
                                              filepath))))
                  (insert (format "#+begin_src %s :eval no\n" progmode))
                  (let ((res (insert-file-contents filepath)))
                    (forward-char (second res)))
                  (insert "\n#+end_src\n"))
                )
            (directory-files path t pattern)))
--8<---------------cut here---------------end--------------->8---

much obliged,
Michael
