Wrong number of arguments error

[shivahnshankar]

I updated the repo today and i started getting these errors:

Warning (initialization): An error occurred while loading ‘/Users/shivashankar/.emacs.d/init.el’:

Wrong number of arguments: (3 . 4), 2

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the ‘--debug-init’ option to view a complete error backtrace. Disable showing Disable logging

Emacs started with --debug-init

I am using Emacs 28.1 with native compilation and chemacs2.

This is coming from the evil-ex project, not Rational Emacs, see: https://github.com/emacs-evil/evil/blob/222b791d3ebed9f58aeb3462522fa9e836fca642/evil-ex.el#L582

However, this version is older and should be updated to a newer version. This line was changed 15 months ago to be in compliance with Emacs 28. (see this commit: emacs-evil/evil@19cc5f8).

Unfortunately, there has not been a release which includes the commit above. Rational Emacs prefers versioned packages for (hopefully) a more stable experience. This depends on packages "releasing" a version of their packages. So, here are the options:

1. Reach out to the maintainers of evil-ex and request a new versioned release (this is simply adding a tag ala: git tag 1.15.0). Regardless if you choose either (or both) of the following options, please do this one.
2. You can pin the evil package to the melpa archive with code like this: (add-to-list 'package-pinned-packages '('evil . "melpa")) do this in your early-config.el file. Stop Eamcs, delete evil from your installation in the elpa/ folder, restart Emacs and you should get the "melpa" version of evil.
3. You can reorder the package priorities. Currently, "melpa" is prioritized lowest because the "version" numbers are only time stamps, but that makes them larger (both physically and numerically) than any stable version. package.el assumes a bigger version number is more recent and will therefore attempt to upgrade to the highest version it finds. We prioritize this lower than every other elpa to defeat that behavior. If you change the priority (or just set package-archive-priorities to nil) you will get the most current commits built in melpa (aka the development versions) of every package. If you choose this step, you don't need to do step 2. If you choose step 2, you don't need this one, but they are not mutually exclusive. You can choose to do them both without hurting anything.

Does this help you?

Thanks....that helped.

Great! If that resolves your issue, can we close this?
