(void-function transient-prefix-object) about magit HOT 3 CLOSED

Perhaps this change should be reconsidered.

What change? "Improving Transient, even though it is now part of Emacs"? 😁

upgrading built-ins is more complicated than external packages.

That's very unfortunate and the result of a bad default. But it's easily fixed: (setq package-install-upgrade-built-in t), basically.

We have the same issue with seq and I recently added a warning that informs users how to fix the issue. I've now done the same for transient.

⛔ Emergency (magit): Magit requires `transient' >= 0.5.0,
but due to bad defaults, Emacs' package manager, refuses to
upgrade this and other built-in packages to higher releases
from GNU Elpa.

To fix this, you have to add this to your init file:

  (setq package-install-upgrade-built-in t)

Then evaluate that expression by placing the cursor after it
and typing C-x C-e.

Once you have done that, you have to explicitly upgrade `transient':

  M-x package-upgrade transient RET

Then you also must make sure the updated version is loaded,
by evaluating this form:

  (progn (unload-feature 'transient t) (require 'transient))

If you don't use the `package' package manager but still get
this warning, then your chosen package manager likely has a
similar defect.

You have to update Transient. transient-prefix-object is a new function.

Duplicate of #5062 and a few others, I believe. Please use the search feature before opening issues.

Perhaps this change should be reconsidered. emacs-29.1 ships with transient 0.4.1 and upgrading built-ins is more complicated than external packages.
