Subject: A small use-package puzzle
Date: Fri, 30 Aug 2024 07:32:34 -0400	[thread overview]
Message-ID: <87cylq8cvh.fsf@rclayton.org> (raw)

I'm running GNU Emacs 29.4 (build 1, i686-pc-linux-gnu, GTK+ Version 3.24.42,
cairo version 1.18.0) of 2024-06-29, modified by Debian, and I'm wondering how
this can happen:

  ELISP> (file-exists-p "/home/rclayton/.emacs.d/elpa/dart-mode-1.0.7")
  nil
  ELISP> (package-installed-p 'dart-mode)
  nil
  ELISP> (executable-find "dart")
  nil
  ELISP> (use-package dart-mode :if (executable-find "dart"))
  nil
  ELISP> (package-installed-p 'dart-mode)
  t
  ELISP> (file-exists-p "/home/rclayton/.emacs.d/elpa/dart-mode-1.0.7")
  t
  ELISP> (executable-find "dart")
  nil
  ELISP>

Maybe there's some weird interaction between ielm and use-package, but when
init.el contains (use-package dart-mode :if (executable-find "dart")) the same
behavior occurs.

Note that

  (when (executable-find "dart")
    (use-package dart-mode))

in init.el behaves as expected.
