Can confirm this is also happening to me. Note also that Invalid function: hs-life-goes-on also appears any time I click anywhere - I assume because it thinks I’m trying to fold something.

[galaunay]

Maybe a missing require somewhere.

Is it better after executing (require 'hideshow) ?

[spluque]

@galaunay requiring hideshow before or after elpy is loaded makes no difference in my case, using the latest elpy from elpa (20200805.1736). As far as I can tell, this issue seems to have been introduced in this latest version.

[nscavalier]

I have the same error message when I use my mouse click on the text.

elpy-folding--click-text: Invalid function: hs-life-goes-on

[nscavalier]

I disabled the elpy code folding module, and the error message is gone.

[galaunay]

hs-life-goes-on is part of Emacs since 19.0 so it should be around.
I tried with a clean Emacs -Q and just Elpy with the folding module activated, and it is not complaining so far.
Do you something related to hideshow.el in your configuration ?

[akovardakov]

Get same error for all folding functions.
Also folding of code blocks like "for" or "if" does not work don't know if this is related or not.

[Yevgnen]

@galaunay hs-life-goes-on is a macro instead of a function on my Emacs. Does it matter?

[mhlr]

The fix is to add (require 'hideshow) to elpy.py. The issue is that hs-life-goes-on is a macro, so it's definition needs to be available when the code using it is being loaded/bytecompiled.

I have submitted a fix in #1952

[mhlr]

What do I need to do to get #1952 reviewed & merged?
