Failure to load in Emacs 25

[DarthFennec]

I'm using Emacs 25.1.1. When I try to run groovy-mode, the mode fails to start, with the following error:

Eval error in the ‘c-lang-defconst’ for ‘c-constant-kwds’ in groovy-mode:
Eval error in the ‘c-lang-defconst’ for ‘c-basic-matchers-before’ in groovy-mode:
Eval error in the ‘c-lang-defconst’ for ‘c-matchers-2’ in groovy-mode:
c-get-lang-constant: Invalid function: (quote ("true" "false" "null"))

I have very little context on elisp and the package itself, but I gave it a try.

Changing the quoting mark did the trick here. Not sure why. It does not work on Emacs 24.5 with this change.

@DarthFennec Debian Sid has now switched from Emacs 24 to Emacs 25 (25.1.1). I just tried editing a Groovy file and did not see the problem you reported. Even though it "works for me", is there still a problem for you?

[russel]

@bltavares The normal quote (') is correct here. Although backquote(`) should work, the extra facilities of that quote form would not be used here so the behaviour using either should be identical.

[DarthFennec]

Yeah, I don't have this problem anymore. No idea what was causing it, seeing as my emacs hasn't been updated since, and this mode hasn't changed in a way that would affect this either. Very strange. Also very strange that the quasiquote would work when a normal quote didn't (by the way, thank you @bltavares for this, it fixed the issue for me in the meantime). But everything seems to work normally now, so I think this is resolved.

[bltavares]

@DarthFennec Yeah, it was odd that ` worked. I don't have the issue anymore. Probably something unrelated, or it was bad compiled file.

[russel]

Good to know it works now. I was having a very hard time thinking what the problem could be. The idea of a badly compiled file that got recompiled would fit, but I am not sure what might have caused that.

Hi,

I experienced a similar problem [1] and managed to fix it by uninstalling and reinstalling the package from within package-list-packages.

Hope it helps.
