Error when attempting to switch tab groups via interactive menu: Symbol’s function definition is void: first

[tomasfarias]

Running:

• Emacs 30.0.50 (2023-06-26)
• Arch Linux
• A centaur-tabs configuration like the recommended one.

Expected behavior

With a mouse, right clicking on a tab, navigating to the tab groups menu, and selecting a different menu should switch to the selected group

Observed behavior

An error is shown:

Symbol’s function definition is void: first

And no switch occurs.

Potential cause

The function centaur-tabs--tab-menu is calling the first function here. From my (short) research, the first from the cl package appears to be deprecated in favor of cl-first provided by cl-lib (see this issue).

Potential resolution

Switching first for cl-first solves the issue (at least in my configuration). I'll open a PR to include this change, but if I'm misguided feel free to close it.

Thank you for making centaur-tabs!
