tab-rename broken/changed?

[T.V Raman]

As best I can tell, something has changed for the worse in tab-rename
-- after you rename a tab, either via C-x tr or from elisp, the alist
of tabs does not contain the explicitly given name, but continues to
use the name of the file currectnly displayed in that tab.

It seems you have a customization incompatible with recent changes.
Do you have this problem when renaming a tab in emacs without customization?
Maybe you are using some elisp code that accesses internal functions?

The latter, fixed it by changing how I was accessing the tab-name.

Could you perhaps provide a simple tab-bar-tab-name function for use
from outside tab-bar (emacspeak in my case) to stay robust?

For now I'm accessing  the name of the current tab like so:

(format "%s"
           (cdr
             (assoc 'name (assoc 'current-tab (tab-bar-tabs)))))

Maybe such function could be added as part of some new Tab API.
But now at least the internal function was reverted to its
previous behavior.

Your change is even more reliable than using internal functions
and until a more general API is implemented.

:-) And rather than waiting for the grand internal API arrives,
perhaps clone the simple solution I have into a
tab-bar-current-tab-name function --- botom-up APIs usually point the
way to the final top-down API

A tab can have more attributes than a 'name',
for example, there is a new attribute 'group'.
So it would be easier to continue accessing
tab data using 'assoc'.  BTW, there is a simpler function
than 'assoc' and 'cdr', just use (alist-get 'name tab).

Also there is an existing function 'tab-bar--current-tab'
to get the current tab.  The only problem is that it's
an internal function whose behavior is not guaranteed not to change.
Than maybe it would be easier just to create an alias to the
internal function, but without -- in its name.

Sorry for the breakage.  The function tab-bar--current-tab was intended
to create a new current-tab structure.  Mistakenly it also supported
searching for the existing current-tab.  Recently the search part was
moved to a new function tab-bar--current-tab-find.

That explains it:-)

See my other reply asking for a stable tab-bar-tab-name function if
possible.
