Hi, Trying out the new exporter and hoping to have it work with o-blog ...
A bug occurs with org-html-format-latex (in ox-html.el) when called from a non-file buffer. In the context of o-blog, it gets called as (org-html-format-latex "$x$" 'mathjax) but still tries to bind some ltxpng related support. This ends up calling file-name-sans-extension to the output of (file-name-nondirectory (buffer-file-name)) which is nil ... Crashing in such a case makes sense for ltxpng but not for mathjax. This makes it work: diff --git a/lisp/ox-html.el b/lisp/ox-html.el index f4fc27b..03e09aa 100644 --- a/lisp/ox-html.el +++ b/lisp/ox-html.el @@ -1994,8 +1994,8 @@ CONTENTS is nil.
