"No description available." for 0xc on melpa?

[xuchunyang]

I notice https://melpa.org/#/0xc and M-x list-packages show "No description available." for 0xc. However 0xc.el does contain a short description (https://github.com/AdamNiederer/0xc/blob/master/0xc.el#L1):

;;; 0xc.el --- Base conversion made easy

Such packages have problems about package header.

I have sent PRs

Oh, I didn't know that.

And from Emacs 25.1, M-x package-install-from-buffer on the previous version of 0xc.el then M-x describe-package 0xc provides a correct short description. In other words,

;; Package-Requires: ((emacs "24.4") (s))

is treated as

;; Package-Requires: ((emacs "24.4") (s "0"))

So I thought there might be something wrong with melpa or the version of emacs used by melpa to create package archive.

0xc issue is fixed by my PR. I think above PRs are merged then this issue is fixed too.

[xuchunyang]

Yes, it's fixed. Thank you.

;; Package-Requires: ((emacs "24.4") (s))

package-lint detects this as an error. Very new versions of package.el allow the above, but that is backwards-incompatible, so it is best to avoid it.

[xuchunyang]

I see. Thanks for telling.
