Subject: 29.0.91; New vc commands missing on vc-menu
Date: Wed, 24 May 2023 19:16:23 +0300

etc/NEWS on emacs-29 contains:

  'vc-print-branch-log' is bound to 'C-x v b l', and new commands are
  'vc-create-branch' ('C-x v b c') and 'vc-switch-branch' ('C-x v b s').

But new commands are not yet added to 'vc-menu-map'.
This patch for emacs-29 fixes this omission:

Thanks.  This is okay, but the help-echo text "needs work".

What is "branch root"?

"the" branch?

Also, AFAICT these commands are not described in the manual.  If they
are important enough to be on the menu bar, I think we should mention
them in the manual as well, no?

Probably better to drop the word "root" to e.g.:

  "List the change log for branch"

Then docstring of 'vc-print-branch-log' could be changed too.

Maybe "the selected branch".  Then it may need an ellipsis:
"Switch Branch..."

They are mentioned briefly in

  (info "(emacs) Creating Branches")
  (info "(emacs) Switching Branches")
  (info "(emacs) Editing VC Commands")

This prompts for the branch to log, right?  Then the menu item should
ends in a "...", and the help text should be

   "List the change log for a branch"

> Then docstring of 'vc-print-branch-log' could be changed too.

Yes, and it should say that the command prompts for the branch to log.

I think

  "Switch to another branch"

Yes.

Mentioned, but not indexed.  Please always index every command
described in the manual, both its name and its key binding (if any).
This is necessary to allow users to find the description of each
command quickly and easily.

Also, vc-print-branch-log is not really described, it's just used in
an unrelated example of using a different feature.

These are fixed in the following patch.

I can't find an existing Info node to document vc-print-branch-log.
(info "(emacs) Branches") has such submenus:

* Menu:
* Switching Branches::    How to get to another existing branch.
* Pulling / Pushing::     Receiving/sending changes from/to elsewhere.
* Merging::               Transferring changes between branches.
* Creating Branches::     How to start a new branch.

Maybe vc-print-branch-log could be mentioned
directly in (info "(emacs) Branches")?

Mentioned there, yes.  But maybe it should be described in full in "VC
Change Log"?
