Subject: 26.1; Undefined functions when calling invoking project.el
Date: Sun, 02 Aug 2020 11:07:27 +0200

When trying to to use some project.el commands, and noticed that there
are a (at least) two undefined functions right after loading project.el
in a vanilla session:

- The first complaint is seq-every-p, used by
  project--read-project-list, but this is "easily" solved by loading
  seq.el.
- The more critical complaint is that assoc-delete-all, used by 
  project--add-to-project-list-front and
  project--remove-from-project-list are not loaded or defined in Emacs
  26.
  My guess is that this function should be replaced by it's functionally
  equivalent code, that only uses functions available in Emacs 26?

To make sure I understand the report: you are using project.el from
GNU ELPA in conjunction with Emacs 26?

Yes, I open Emacs 26, and load ~/.emacs.d/elpa/project-0.5.0/project.el.

I see that seq has been added as a dependency in the git repository
(that appears to not have been released to ELPA yet).

The patch attached below should fix the assoc-delete-all issue.

Thank you for testing that.

That is already fixed on master, should be in the next project.el release.

seq-remove, cl-delete-if (or even cl-delete with :key) seem like the 
prime candidates.

Thanks!

Could you add a commit message as well, formatted according to CONTRIBUTE?
