Dear Stardiviner,
I used the "scimax" configuration. Scimax's maintainer, John Kitchin,
helped me out to find the root cause of the problem, i.e. the following
addition to " python-font-lock-keywords":
(setq python-font-lock-keywords
(append python-font-lock-keywords
'(;; this is the full string.
;; group 1 is the quote type and a closing quote is matched
;; group 2 is the string part
(
;; "f\\(['\"]\\{1,3\\}\\)\\([^\\1]+?\\)\\1"
"f\\(['\"]\\{1,3\\}\\)\\(.+?\\)\\1"
;; these are the {keywords}
("{[^}]*?}"
;; Pre-match form
(progn (goto-char (match-beginning 0)) (match-end 0))
;; Post-match form
(goto-char (match-end 0))
;; face for this match
(0 font-lock-variable-name-face t))))))
Commenting out this code snippet, the fontfying / HTML-export problem goes
away.
Cheers,
sebastian
