Add one step generator for new projects

[wende]

Add:

Example:

elmchemy new my_project
mix test 
# 0

->

my_project/
├── elm-package.json
├── mix.exs
├── elm
    ├── Hello.elm
├── lib
    ├── Hello.ex
├── tests
    ├── hello_test.exs

I technically could do that.

Shouldn't files be named after project name or something? What contents should those files have?

[wende]

They (elm/File.elm, tests/file_test.exs) could be parametrized to the name of the project. The main idea is to cut the boilerplate and hopefully generate something self-explanatory code with benefits of learning all the essential basics with just a template

[Hajto]

@wende Do you still want to store files under Elm directory after name change?

[Hajto]

@wende Mix task is created and it does work. It needs more testing though. I have no idea how to put in production.

Sample usage. Go into installer and call:

mix elchemy.new erlang_style_name --location where_to_put_files

Also help needs to be written.

@wende Do you still want to store files under Elm directory after name change

That's a good question actually. I think it's worth leaving it as it is until we're using .elm extension and Elm tooling

@Baransu Let me know when you're feeling like picking up this issue
