## Warning: This app executes code dangerously, use with caution

The ideal case for this app is to have it deployed in a Docker container with an exposed API where it can do little to no harm.

## Currently Supported Languages

- elixir

- ruby

- node (any Javascript that Node can run)

## Install

Make sure that you have whatever language(s) you want to use

installed/available on the machine you will be running this on.

Add executor to you dependencies in `mix.exs`

```elixir

defp deps do

  [

    {:executor, "~> 0.0.3"},

  ]

end

```

Then install

```bash

mix deps.get

```

## Usage

Common API looks like: Executor.Language.run("code as string")

Example in IEx:

```elixir

# ruby

iex(2)> Executor.Ruby.run "1 + 1"

{:ok, %{return: "2", stdout: ""}}

iex(2)> Executor.Ruby.run "[].upcase"

{:error,

 %{error_message: "undefined method `upcase' for []:Array",

   error_type: "NoMethodError", return: nil, stdout: ""}}

iex(3)> Executor.Ruby.run "puts 'hello'; [1,2,3]"

{:ok, %{return: "[1, 2, 3]", stdout: "hello"}}

# node

iex(4)> Executor.Node.run "1 + 1"

{:ok, %{return: "2", stdout: ""}}

iex(5)> Executor.Node.run "1 / 0"

{:ok, %{return: "Infinity", stdout: ""}}

iex(6)> Executor.Node.run "apple.juice()"

{:error,

 %{error_message: "apple is not defined", error_type: "ReferenceError",

   return: nil, stdout: ""}}

   

iex(7)> Executor.Node.run "console.log('hello world')"        

{:ok, %{return: "undefined", stdout: "hello world"}}

# elixir

iex(9)> Executor.Elixir.run "1 + 1"

{:ok, %{return: "2", stdout: ""}}

iex(10)> Executor.Elixir.run "0 / 0"

{:error,

 %{error_message: "bad argument in arithmetic expression",

   error_type: "ArithmeticError", return: nil, stdout: ""}}

iex(11)> Executor.Elixir.run "IO.puts \"hello world\""

{:ok, %{return: ":ok", stdout: "hello world"}}

# pass language as argument

iex(12)> Executor.run "1 + 1", "ruby"

{:ok, %{return: "2", stdout: ""}}

```
