Hi guys. I just wanna create a package and assing a binding to that function. Any tutorial or document ?

@scknkkrer checkout this guide: it does a pretty good job of explaining all of spacemacs configuring

http://thume.ca/howto/2015/03/07/configuring-spacemacs-a-tutorial/

How can I fetch a package from github ? I couldn’t find any example.

check this snippet out:

dotspacemacs-additional-packages
'(
  (mypackage :location (recipe :fetcher github :repo "githubuser/mypackage"))
 )

part of this FAQ https://github.com/mbertheau/spacemacs-faq/wiki#how-do-i-install-an-emacs-package-from-github

I did that. But my package doesn’t load. How can I debug the problem ?

@scknkkrer I would check the *messages* buffer first to see if it reports an error when it tries to load it.

(Probably at SM startup time)

gotta love those SM startup time error messages

Wait, it install my package from source.

But it doesn’t load the functioncs inside it.

Ah, you probably need to add (require 'my-package) to your user-config.

IIRC

But, use-package function don’t that for me ?

Oh. I would expect it to, on the face of it. Not sure I've actually used use-package, it just sounds like it would 😆

So, it will live ? 😂

yeah, it won't autorequire things

that would defeat the purpose of spacemacs' lazy loading

well, it won't unless the package config tells it to

Chris, here is the thing. I started development on spacemacs yesterday. I read a lot. But every documentation shows the things from far away. so tiny perspective.

(defconst exercism-layer-packages
  '(evil-magit (exercism-mode :location (recipe :fetcher github
                                                :repo "LeaveNhA/exercism-mode"))))

(defun exercism-layer/post-init-evil-magit ()
  (with-eval-after-load 'magit
    (require 'evil-magit)
    (evil-define-key 'motion magit-mode-map
      (kbd dotspacemacs-leader-key) spacemacs-default-map)))

(defun exercism-layer/init-exercism-mode ()
  (use-package exercism-mode
    :defer t))

(defun exercism-layer/post-init-exercism-mode ()
  (progn
    (spacemacs/declare-prefix "E" "Exercism")
    (spacemacs/declare-prefix "Ex" "Exercise")
    (spacemacs/set-leader-keys
      "Exf" 'exercism-mode/fetch-new-exercise
      "Exs" 'exercism-mode/send-solution-to-exercism)))

I need magit but not as owner layer. so I do my init in post-init stage.

I add my mode package from github.

It really install my package from there.

But when I don’t define the package functions in my layer. It says invalid commandp……. I think it really don’t load my mode properly.

@scknkkrer you might want to consider bringing it up in the Spacemacs gitter -- that seems to be where a lot of the SM devs hang out. https://gitter.im/syl20bnr/spacemacs

I did. They laugh at me.

Sorry to hear that.

“Community-Driven”

Says on my sapcemacs.

Ironic…

@eggsyntax also, when I require the package, it says; Required feature was not provided

Definitely way outside my expertise; I've never tried to do anything at all complicated with packages. I mostly stick with existing layers.

https://github.com/LeaveNhA/exercism-layer

I just did.

If anyone who use http://exercism.io for exercise in spacemacs.

You can use this.

Nice work @scknkkrer! Just curious, have you opened a PR to add the layer to core spacemacs? That'd be neat to see.

Did you get all your problems straightened out?

Not yet. It’s too empty right now. I have to implement another features.

I am glad you like it.

@eggsyntax I am with you on that!

oh what a cool idea @scknkkrer!

@scknkkrer I believe you need layers.el in your dir. where you declare layers that your layer depends upon

in that file you'd add something like (configuration-layer/declare-layers '(git))

I didn’t use any external layer.

well, you need magit, magit is already comes with git layer, if you want layers to load in order I think you need to do that

Opps. wait a minute. 😞

I removed it.

Thanks for the inform.
