EDTS in elisp package repository?

[qrilka]

I'd be convenient to have a possibility to install EDTS from any emacs lisp packages repository (elpa/melpa/marmalade)
I don't know much about the process of adding a new package though.
And distel is supposed to go this way - massemanet/distel#21

Please see #52

"EDTS has non-elisp (specifically Erlang) dependencies, that are not available to install from package.el
EDTS requires compilation of its Erlang modules as part of the install procedure which can't be done in package.el"

[qrilka]

As I understand disterl also needs to have beam available and they are planning to solve it somehow

[josephDunne]

That ticket has been open for 10 months now so I wouldn't hold your breath. The only mechanism I can think of is to distribute the .erl files and compile them when edts is first initiated. @tjarvstrand what do you think? If we explained that the initial startup would hang Emacs while it compile it might work.

[tjarvstrand]

Yeah, AFAIK there's no way to compile the Erlang binaries at install time using package.el. There's also no way to depend on non-elisp packages (such as Erlang).

@tjarvstrand We can do this with little helper function like edts-install. I add something similar to my 'company-jedi' package for python dependencies resolution.

Or even this:

(eval-when-compile
  (let ((default-directory (file-name-directory load-file-name)))
     (compile "make")))

Also I think moving project to Cask instead of git submodules will help with this direction.

[tjarvstrand]

Yeah, that looks like it could be get us part of the way. Unfortunately it will fail if erlang, make, or git is not installed on the machine.

Moving to Cask may work for the elisp dependencies but there are a number of erlang ones that will still have to be fetched using git in some way.

[proofit404]

Fail without git, make or Erlang is normal I think. But having emacs dependencies managed in emacs way is really necessary because user can install or update edts in the same way as any other emacs package.

Unfortunately it will fail if erlang, make, or git is not installed on the machine.

Seems fine to me as long as it is documented,

[tjarvstrand]

Looking into it

[goofansu]

You can use el-get to install edts. I just send a PR to it.

It just git cloned edts into ~/.emacs.d/el-get/edts and invoke make.

Here is my usage: https://github.com/goofansu/prelude/blob/master/personal/preload/init-el-get.el

[tjarvstrand]

EDTS should now be more or less ready for installation using package.el. You can follow the progress in melpa/melpa#1651

[proofit404]

Nice work!
