Development Machines

[shiroyasha]

Hi guys,

I would like give it a shot and try to help with issues/development/etc. What is your preferred development environment while working on elixir? Do you have a recommended vagrant machine, or a docker image that you use for development?

Thanks,

Igor

Welcome! We don't have an official vagrant machine but maybe someone has made one available. Developers should be just fine on Mac or Linux. It may be not as straight-forward on Windows, but they are guides on the wiki to get the C compilers working.

Thanks for the fast reply. I'll try to look into what is available.

I have no issue with it on Windows but I have a heavily modified bash shell (not Windows 10's bash shell) with mingw that works fine.  :-)

I have played around with the idea of using docker as a development environment for developing elixir. It works very nice, and it would allow us quickly compile on more than one OTP platform without dirtying our host machines (e.g installing kerl and compiling various erlang versions).

The development flow would be the following:

1. First, you open a terminal, navigate to the root of the project, and start a development machine. For example, you would type docker-compose run erl192 to compile/test your code based on Erlang 19.2. This starts a bash shell, and shares(mounts) the projects into the docker image.

2. You edit the code, either on your host machine with Atom for example, or from inside of the docker image with Vim and when you are happy with the changes you can type make test in the bash shell from the running docker image.

This could be also used as the base for testing in the CI environment, but I am not sure of the performance penalty.

I got a successful (green) build for every docker image (erl_18.1, erl_18.2, erl_18.3, erl_19.0, erl_19.1, erl_19.2, erl_19.3)

Let me know if you like this idea.

I developed an Elixir app in docker for a couple months. If you're doing it on linux where it can natively run it'll probably work great. I noticed a significant boost in speed when compiling outside of a container on mac. The disk access for docker on mac is slower because it has to go through a couple layers on mac.
