Subject: Have SRC_BLOCK :padline accept numbers
Date: Tue, 28 Mar 2017 21:47:42 +0200 [thread overview]
Message-ID: <CAJTMgxg0+bub2OzaKhUVN32O3iLWe44OkyS1P0nb-4H8z-PT=w@mail.gmail.com> (raw)
[-- Attachment #1.1: Type: text/plain, Size: 703 bytes --]
A use case is tangling python source code snippets containing class
definitions.
(
http://emacs.stackexchange.com/questions/31738/org-mode-babel-ensure-two-empty-lines-between-tangled-code-blocks-for-python
)
Per PEP8, the use of blank lines stipulates:
"Surround top-level function and class definitions with two blank lines."
To achieve two blank lines before a class definition, one would have to set
:padline 2.
I've written a small patch (attached here), following the contribution
guidelines on the org-mode website. The "patched" repository can be found
here: https://github.com/dangom/org-mode/tree/feature_padline
Please let me know if there is anything else I should do.
Thanks,
Daniel
