Re: Appropriate way for package to require seq for Emacs 24.5?

I apologise for the previous garbled message.

May I ask the appropriate way for a package to require seq for Emacs 24.5?

Currently I have:

> Package-Requires: ((emacs "24.5") (seq "2.20"))

However, I see in the seq commentary:

> While seq.el version 1.8 is in GNU ELPA for convenience, seq.el
> version 2.0 requires Emacs>=25.1.

Am I correct in interpreting that the above package header would not
work with 24.5?

If so, would this work?

> Package-Requires: ((emacs "24.5") (seq "1.11"))

Thank you, and again, sorry for the previous MIME noise.

AFAICT it would work fine in 24.5: package seq-2.20 does not require
Emacs-25, instead it comes with both the "old" API for Emacs-24 and the
new API for Emacs≥25 (concretely these are divided into two files
(seq-24.el and seq-25.el) which are the two alternative implementations:
the API is slightly different because seq-25.el uses cl-generic so it
can be used with sequences other than lists, vectors, and strings).

Why though? We are on two major versions on and about to be three?

Cool, thank you.

I would like to drop 24 but even after recently bumping the requirement
to 25 someone complained that their Linux Mint distro only had 24.

I’ll drop it as soon as it causes me the slightest annoyance, but for
now it seems okay.

Hello William,

JFTR, to inform anyone (who might not know) reading this and using Gnus:

  W 6 (gnus-article-de-base64-unreadable)

come in handy.
