Subject: 30.0.92; `emacsclient-program-name' doesn't factor Emacs name changes
Date: Fri, 1 Nov 2024 16:51:32 +0900

Emacs 30 adds the `emacsclient-program-name', but its default value
doesn't factor the build time Emacs name configuration changes (with
prefix, suffix and sed transormation). I only verified this with the
suffix confguration, but assume prefix and sed transformation are the
same.

In my case I configured with `--program-suffix=-30pre'. The Emacs client
program is, as expected, `emacsclient-30pre', but the value of
`emacsclient-program-name' is still `'emacsclient'. The variable value
should reflect the configure time name change(s).

This would make `with-editor' simpler (from Emacs 30 onward) as no
heuristics would be needed to derive the Emacs client name. See:

Thanks

It's actually more complex than that: the programs are renamed only
when Emacs is installed, not when Emacs is built.  So when Emacs is
run from the build tree, this variable should have its original name,
and only when Emacs is run from its installed location, the name
should reflect the transform.  Which means the name transformation
cannot be static, at build time; it must be done at run time when we
take note of invocation-name.

It's too late for Emacs 30 for such non-trivial changes,
unfortunately.  So we can only improve this in Emacs 31.
