From 7c3300ace135e94467942f77f0a2c07a93ab00ad Mon Sep 17 00:00:00 2001 From: cnngimenez Date: Mon, 10 Jan 2022 15:30:46 -0300 Subject: [PATCH] Bug fixed when section has no text but has properties. An error appeared when a header has no text but it has properties. For instance: ```org * A header :PROPERTIES: :ID: 7159694c-0e06-41d6-a2fc-1ae3f9ba0321 :END: * Another header ``` "A header" is processed by `org-gemini-section` and throws error when exporting: `contents` parameter is nil instead of empty string. "Another header" is considered a headline and not a section. --- ox-gemini.el | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/ox-gemini.el b/ox-gemini.el index cb8322f..07081da 100644 --- a/ox-gemini.el +++ b/ox-gemini.el @@ -116,7 +116,9 @@ Note: the footer with the actual links are handled in "Transcode a SECTION element from Org to GEMINI.
