Re: latex fragments compilation error when exporting to html

[Jeremie Juste]

Hello,

I have found the culprit in the end. It was the function
org-html--unlabel-latex-environment, int he ox-html.el file.

I'm not sure this function is useful as I think it is better to give the
user control on his environment (labelled or unlabelled) directly in his
org file. I'm I missing something else about the use of this function?

Anyway it was a good experience at debugging elisp.


diff --git a/lisp/ox-html.el b/lisp/ox-html.el
