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: #<subr progn>
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!

Fontification and export work fine with this code block for me. Does the error still happen when you use emacs -q ? Or if you use 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!

All it should do is improve font-lock on Python f-strings, and it used to work fine, but now it doesn't. It isn't real critical for me, so I don't mind commenting it out, but I neither understand why it stopped working!

I haven't tested to confirm, but I'd guess that is due to the restructuring of python-font-lock-keywords in 36b64e087e (Add 'font-lock-maximum-decoration' levels for Python, 2018-07-19), which was included in Emacs 27. In case it's helpful, here's the compatibility kludge I used in snakemake-mode: https://git.kyleam.com/snakemake-mode/commit/snakemake-mode.el?id=5d5bb0109f6a84c0c191559ab71670fae4650e6a ^ permalink raw reply [flat|nested] 9+ messages in thread
