Field	Explanation
entrypoint	This is the name of the file that you want to run. For example main.py
stdin	This is the standard input that is set before running the program. Standard input is the way you pass data into the program.
language	This compiler supports 4 Languages. Choose one using the selector
zip file	This is the zip a folder of all the files that conatin your code.It is very important that your folder name and zip name are exactly the same (should not contain spaces). Note that one of these files should be your entrypoint

Making an API call

In order to make an API call to this compiler, you will first need a form of the following structure

<form enctype="multipart/form-data" onsubmit="handle();" id="myForm">
    <div class="entrypoint">
        <label for="entrypoint">Enter entry point</label>
        <input type="text" name="entrypoint"/>
    </div>

    <div class="input_text">
        <label for="input_text">Enter stdin</label>
        <textarea type="text" name="input_text"></textarea>
    </div>

    <div class="language">
        <label for="language">Choose Language</label>
        <select name="language">
            <option value="python">Python</option>
            <option value="C">C</option>
            <option value="C++">C++</option>
            <option value="java">Java</option>
        </select>
    </div>

    <div class="myCode">
        <label for="myCode">Upload Zip File</label>
        <input type="file" name="myCode"/>
    </div>

    <button type="submit">Submit</button>
</form>

Next you will need to write JavaScript to make the API call.

function handle() {
  var myForm = document.getElementById("myForm");
  var formData = new FormData(myForm);
  var url =
    "http://compiler-env.i3hveummcp.ap-southeast-1.elasticbeanstalk.com/";
  var options = {
    method: "POST",
    body: formData
  };
  fetch(url, options)
    .then(res => res.json())
    .then(json => {
      console.log(json);
      //Do whatever you want with this JSON response
    });
}

Response

If everything works out perfectly, you will recieve a response of the following structure

{
    "stdout":"A string that will contain the standard output of the code",
    "timeTaken": "An integer that will represent time taken to run this code in milliseconds",
    "memory":"A string that will contain the total memory used by the code."
}

Example output

{
    "stdout":"Hello World\n",
    "timeTaken":1443,
    "memory":"1.126 MB"
}

If there is an error, the API will send back the following resonse

{
    "error":"A string that describes the error"
}

Example output (This was a python code that had prin("Hello World"))

{"error":"Command failed: valgrind --tool=massif python3 data/myCode/main.py\n==51== Massif, a heap profiler\n==51== Copyright (C) 2003-2017, and GNU GPL'd, by Nicholas Nethercote\n==51== Using Valgrind-3.13.0 and LibVEX; rerun with -h for copyright info\n==51== Command: python3 data/myCode/main.py\n==51== \nTraceback (most recent call last):\n  File \"data/myCode/main.py\", line 4, in <module>\n    prin(\"Hello world\")\nNameError: name 'prin' is not defined\n==51== \n"}
