slack-compilebot

Like /u/compilebot, but for Slack.

The Basics

All you have to do is mention CompileBot in a thread, or send it a direct message, along with a language and source code:

@compilebot python

print("Hello World!")

CompileBot will then process your message, execute it remotely, and then respond with the output:

Output:

Hello World!

Code blocks are done with three backtics (```) in Slack:

```
code here
```

Supplying Input

You can also give an input block that the program will use as Stdin:

@compilebot python 3

n = int(input())
while n != 42:
    print(n)
    n = int(input())

Input:

1
2
10
42
11

Make sure the word "input" is written before the code block followed by a colon. Also make sure the line with "input" is not included in a code block. CompileBot will take the block and supply it as standard input to the program:

Output:

1
2
10

Options

You can supply additional options in your comment that will signal CompileBot to display additional information. You can place these options after the programming language on a new line and before the code block.

@compilebot Ruby
time memory

x = 1
50000.times { x *= 10 }
puts x / 10 ** 50000

Reply:

Output:

1

Memory Usage: 75776 bytes
Execution Time: 0.48 seconds

How it works

CompileBot runs off the slackbot API, and uses the Sphere Engine API to execute the code.

Note that Sphere Engine no longer is giving out free forever accounts, so unless you already have a free account and an API token, you will need to make a trial account.

Inspired by compilebot for Reddit.

Contributing

Even if you don't want to contribute to the compilebot source, we need people for testing and improving documentation.

If you would like to contribute new features, or fix bugs or contribute anything else to the compilebot module, you can follow the instructions below to get a local instance of compilebot set up on your system.

Installation

Docker

Running on Docker is the simplest way to setup the bot. You will need a Slack bot token and a Sphere Engine API token.

Run the container with docker-run or docker-compose:

docker run --name=slack-compilebot \
    --restart=always \
    -e SE_API_TOKEN=token \
    -e SLACK_BOT_ID=UXXXXXXXX \
    -e SLACK_API_TOKEN=xoxb-XXXXXXXXXXXX-XXXXXXXXXXXXXXXXXXXXXXXX \
    rycieos/slack-compilebot

version: '2.3'
services:
  slack-compilebot:
    image: rycieos/slack-compilebot
    restart: always
    environment:
      - SE_API_TOKEN=token
      - SLACK_BOT_ID=UXXXXXXXX
      - SLACK_API_TOKEN=xoxb-XXXXXXXXXXXX-XXXXXXXXXXXXXXXXXXXXXXXX

Env options:

• DEBUG: Default False. If True, print debugging messages in the logs.
• SE_API_TOKEN: The Sphere Engine API token to use for authentication.
• SE_API_ENDPOINT: The URL endpoint. The default is probably good.
• SLACK_BOT_ID: The Slack bot ID to respond to, in UXXXXXXXX format. It's easy to get from the webapp by "Inspect Element"ing the @bot username.
• SE_API_TOKEN: The Slack token to authenticate with. Can be generated at the old style bot page.
• ERRORS_TO: The slack username (not user ID) of the user to report bot errors to. Could also be a channel name (not channel ID). This will not be compile errors, but actual errors with the bot. Optional.

Local

Requires Python 3.4+

git clone git@github.com:Rycieos/slack-compilebot.git
cd slack-compilebot

Setup a virtual env and download dependencies

virtualenv venv
. ./venv/bin/activate
pip install -r requirements.txt

Copy default settings and set them. You will need a Slack bot token and a Sphere Engine API token.

cp slackbot_settings.py.dist slackbot_settings.py
#edit slackbot_settings.py

Finally, run it:

python run.py

Supported Languages

CompileBot supports any language that is supported by ideone. Chances are CompileBot can process any language you would want to use. However, if the language you are looking for isn't available, you can contact Ideone/Sphere Engine to add a new one, and CompileBot will automatically support it.

Some languages need an entry point, like int main() in C. All languages use the standard for the language. For Java, the main() method needs to be in the public class Main. For C#, the Main() method needs to be in the public class Test.
