Re: Org mode fontification error in # in python and ipython source blocks
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

Re: Org mode fontification error in # in python and ipython source blocks
Hi Jack,
I have cloned the git master. Running without configuration ("make
vanilla"), emacs correctly fontifies the source block and it also gets
exported to HTML. It seems that it is a configuration problem. Sorry for
not double checking first!
Many thanks for your help!
Cheers,
Sebastian

Re: Org mode fontification error in # in python and ipython source blocks
Hi Jack,
thanks for replying!
The error does not happen using "emacs -q" (built-in package: org 9.3). I
haven't tried with the git version yet. i will and let you know.

Org mode fontification error in # in python and ipython source blocks
Hi,
I am using emacs 27.1 and org-plus-contrib 20201026.
I am having problems with the fontification of python and ipython source
blocks when the code contains curly brackets "{}" (other course blocks are
ok). For instance, the following snippet
#+BEGIN_SRC python :results drawer
import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.show()
a=1
print("a={}".format{a})
#+END_SRC
does not fontify correctly in either python or ipython source blocks.
As a consequence, when exporting the org file to HTML (C-c C-e h h), it
fails with the following message:
font-lock-fontify-keywords-region: Invalid function: #
If changing the code snippet to:
#+BEGIN_SRC python :results drawer
import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.show()
a=1
print("a=%s" % a)
#+END_SRC
the block fontifies and the file is exported to HTML correctly.
Can you reproduce this behaviour?
Many thanks in advance!
