:loader :path packages keep trying to get installed

[ivan-m]

I have a few files that I've picked up along the way that aren't available via package.el. Previously I had just either autoloaded or require'd them.

I'm now trying to load them up using req-package but it doesn't seem to work; for example if I have this in my config:

(req-package hs-lint
  :loader :path
  :commands hs-lint)

But when I try and launch Emacs I get the following backtrace:

Debugger entered--Lisp error: (error "Package ‘hs-lint-’ is unavailable")
  signal(error ("Package ‘hs-lint-’ is unavailable"))
  error("Package `%s-%s' is unavailable" hs-lint "")

I tried to add in :pin manual, which didn't seem to affect it.

Should req-package set :ensure nil when :loader :path is used?

[ivan-m]

Also jwiegley/use-package#190 (and I do have (setq use-package-always-ensure t)).

[edvorg]

Hi. Regarding always-ensure this should not be used with req-package. req-package has a providers system, which is more feature rich than the one we have in use-package.

[edvorg]

Investigating your load path related issue.

[edvorg]

Ok. So, I believe this is how you should use :path loader

(req-package test-foo
  :loader :path
  :load-path "/home/edvorg/Documents"
  :config (message "test %s" test-foo-value))

[ivan-m]

Oh, it can't pick it up from the existing load-path? I might stick with autoloads for them then.

[edvorg]

I think this might be a good way for further improvement ;)

[edvorg]

Actually I'm looking at this function now @ivan-m . And I think the we support what you want, but there is possibly some bug there

(defun req-package--load-path (package)
  (append (ht-get req-package-paths package nil) load-path))

Here we merge the system load-path with the provided one. Need to check, why it doesn't work for you.

[edvorg]

Yes, it actually works @ivan-m . You don't even have to specify :loader :path, because req-package will walk through all the providers and check if any one has your package. just make sure that you put provide call in your path located files and setup your load-path before requiring any packages.

Could you please confirm if it works for you now?

[edvorg]

The bar.el file contents from example above

(defconst bar-var 9)

(provide 'bar)

[ivan-m]

That seems to do it, thanks!
