Sub-libaries in a package and use-package ?

Sub-libaries in a package and use-package ?

[David Masterson]

The 'async' package has 2 extra libraries (dired-async &
smtpmail-async). I'm trying to figure out how to set these up with
use-package, The documentation for use-package in chapter 3.1 says:

----
But the ‘foo’ package might also contain a library named ‘foo-extra.el’.
If that library is not loaded automatically, you will need a separate
‘use-package’ declaration to make sure that it is.
----

It doesn't say anything else about this (CMIIAW), but this suggests to
me that the following should work:

(use-package async
  :config (async-bytecomp-package-mode 1)
  )
(use-package dired-async
  :config (dired-async-mode 1)
  )
(use-package smtpmail-async
  :config (setq message-send-mail-function 'aync-smtpmail-send-it)
  )

But the following error when I start Emacs:

Error (use-package): Failed to install dired-async: Package
  ‘dired-async-’ is unavailable 
Error (use-package): Failed to install smtpmail-async: Package
  ‘smtpmail-async-’ is unavailable 

This suggests that use-package can't find the *package* when all it
should be doing is picking up the library in async which already
established the load-path.

What am I missing?

Did you set `use-package-always-ensure' to a non-nil value?  It might be
that use-package is trying to install the package
{dired,stmpmail}-async, even though these are just libraries, part of
the async package.

Also, I don't think it is necessary to configure all of these
separately, at least in your case.

Hmm. I do have 'use-package-always-ensure' set to t, but it doesn't look
like it's trying to install -- it just can't find the package.  There
should be a mechanism to tell use-package that this is a library in some
other package,

Possibly true.  I can get around this by requiring the sub-libraries in
the :config section of async.  But that doesn't quite feel right,,, :(

It cannot install the packages, because they don't exist.  Perhaps
adding a :ensure nil could help?

I'd question why you need to require the libraries in the first place.

Ah!  This seems to work good:

----
(use-package async
  :delight
  :config (async-bytecomp-package-mode 1)
  )
(use-package dired-async
  :ensure nil
  :config (dired-async-mode 1)
  )
(use-package smtpmail-async
  :ensure nil
  :autoload async-smtpmail-send-it
  :init (setq message-send-mail-function 'async-smtpmail-send-it)
  )
----

The async package seems to have made the decision that, if you want to
do dired/smtpmail asynchronously, then require the sub-libraries.  I
thought I'd try it to see if I have a problem, but, since there are
cases where it might have a problem, I might turn it off again which I
could do with :disabled in the sub-library packages if it worked.
