cannot enable xenops-mode on emacs 29

[lyjdwh]

I install gccemacs on archlinux with sudo pacman -S emacs-native-comp-git and get the following error when enabling xenops-mode

Debugger entered--Lisp error: (invalid-function (ov (and (not (or parse-at-point-fns no-recurse)) (xenops-overlay-at-point))))

I have the same issue.
@lyjdwhc BTW, the AUR package emacs-native-comp-git is outdated for the branch feature/native-comp has been merged into master branch. You can install emacs-git directly.

Same issue here for emacs 28 with native comp enabled on mac os and gentoo.

Same issue on Emacs 28.0.60 built with native-comp on Gentoo.

Seems like the native compilation has bugs. I simply deleted all the xenops-xxxxx.eln files in ~/.emacs.d/eln-cache/28.0.60-xxxxxx, then everything works fine.

[VitalyAnkh]

@lizhuohua Awesome! It's a great workaround. Just don't know how to blacklist xenops-mode from native compiling...

[dandavison]

Hi all, thanks for investigating this. So, when installing from MELPA in Emacs 28 with native-comp, I see many compilation warnings, but in particular I see various "malformed function" warnings like

Warning (comp): xenops-parse.el:14:72: Warning: `(ov (and (not (or parse-at-point-fns no-recurse)) (xenops-overlay-at-point)))' is a malformed function Disable showing Disable logging

which appears to be related to the runtime error reported above. All of these "malformed function" warnings seem to be related to usage of the -if-let* macro from dash.el. Furthermore, for each of the affected files, I see a compilation warning like this

Warning (comp): xenops-parse.el:26:4: Warning: the function `-if-let*' is not known to be defined. Disable showing Disable logging

So, I am wondering whether the problem is that I am not making the required forward declaration of -if-let*. I don't know why that would be a problem on native-comp and yet apparently wasn't with standard byte compilation. In any case, if anybody knows the exact change that I need to make, do shout out.

I've merged #29 which I hope will fix this. I believe MELPA will pick that up automatically at some point in the next few hours. If anyone is able to tell me exactly where in the package files I should be using (require 'dash) and where (eval-when-compile (require 'dash)) that would be great.

[dandavison]

These issues should be fixed if you reinstall from MELPA now.

M-x package-delete xenops
M-x package-refresh-contents
M-x package-install xenops

[lizhuohua]

Thank you @dandavison !

Reinstalled from MELPA and now it works perfectly.
