Loading arbitrary packages during plain iex sessions

[Abdullah Esmail]

Hello,

I believe it would be extremely helpful to old and new elixir developers to be able to try out packages without the need to create a whole project.

Developers coming from different backgrounds (python, ruby, etc) are used to getting into the interactive shell and just importing/requiring the package they need and start playing with it.

I don't know if this is technically possible with iex, but it would definitely change how I work with elixir in general.

Something like:

iex --hex <package1> <package2>

Even if it takes longer to start, at least I could try those packages without creating a dummy project and including those packages as dependencies and then compiling everything.

One command to rule them all.

Maybe `iex --hex` could create a temporary dummy project behind the scenes?

For what it's worth, I'd be very willing to help work on implementing this if it's going to happen.

I apologize if this has been discussed or brought up before. I couldn't find a similar topic.

It's possible to experiment with this by creating a custom mix task, installing it as an archive and then running `iex -S mix try.package ...`.

This is a nice proposal, but I'd rather have this go all the way and allow me to pull Hex packages while maintaining the current IEx session, so something like:

$ iex --hex

iex> Something.deps_get :some_http_client, "1.0.0"

iex> SomeHttpClient.get(...)

Best,

Stefan

I would love to see (some version of) both the original proposal and this one.  They would make IEx a lot more useful.

Thanks,

The issue is, those packages need to be compiled and in a specific order, how would that work? `hex` isn't a build tool, `mix` is.

I like this idea, but I do believe that creating something like this will necessarily require certain opinionated decisions to be made.
As such, it might be more suitable to be a custom Mix archive that will not be included (nor maintained) as part of Elixir itself.
