✏️ In short

Note This project was initially done in a week so do not expect crazy behavior and be immune to bugs.

This is a Discord compiler bot which can compile / interpret code blocks and display the result. Keep in mind that we're working in discord. This means, of course, that we have many operating restraints. Here's a few of the big ones.

• Complicated syntax for non-trivial compilations
• Limited output length (limited to a couple hundred characters)
• Single-file input only

Please read the Wiki for more.

👩‍🏫 Usage

First you should install the Rust programming language for your operating system. Then, you should create a new .env file on the model of the .env.example. You should at least set BOT_TOKEN and APPLICATION_ID (you can let other fields untouched) environnement variables.

cargo run --release

The bot should then connect to the servers and if succesfull, show a list of debug commands on the go.

💁 Get Help

While in discord, please type ;help to get generic help and show a list of available commands, or type ;help <cmd> to get help about a specific command. Here is a list of the most usefull ones.

• ;format on a code block with the language set will trigger a format command for the language
• ;compile will compile and run a code block with the given language
• ;languages will show a menu to display all languages
• ;asm will transform the code block into Assembly _x86_64 for linux

🔰 Support

Support for following languages : c++, c, java, python, ruby, rust, javascript, go, php, lua and many more.

On a side note, support has been added for ARM architectures. Meaning you can now host the bot yourself on a Raspberry PI without any tweaks to the code ! But you will need to compile it yourself though...

🧪 Testing

Oh god... please don't.

Still, make sure you have valgrind up and ready and then run :

cargo test --all

🧑‍🏫 Contributing

If you ever want to contribute, either request the contributor status, or, more manually, fork the repo and make a full request !. On a more generic note, please do respect the Rust Coding Conventions and wait for your PR to be reviewed. Make sure you respect and read the Contributing Guidelines, make pull requests and be kind.

The standard procedure is :

fork -> git branch -> push -> pull request

Note that we won't accept any PR :

• that does not follow our Contributing Guidelines
• that is not sufficiently commented or isn't well formated
• without any proper test suite
• with a failing or incomplete test suite

Happy coding ! 🙂
