RCaron

A .NET shell and scripting language. It is currently unusable as a shell, a little usable as a scripting language. You can also call it ř or Ř.

Documentation for the language is available at rcaron.jan0660.dev.

A simple number guessing game currently looks like this:

// we "open" a .NET namespace with open
open 'System'
// to use a .NET type we start it's name with a '#' and then access it's members with ':'
// from there we access the members of a variable, property or whatever with '.'
// variables don't have to be declared
$number = #Random:Shared.Next(1, 10000)
print 'Guess a number between 1 and 10000'
// 'loop' is a loop that can be exited with 'break'
loop {
    #Console:Write('Your guess: ')
    $guess = #Int32:Parse(#Console:ReadLine())
    // 'print' is a built-in function that prints arguments to the console with a space between them
    print 'You guessed:' $guess
    // operators look normal
    if ($guess < $number) {
        print 'Too low'
    }
    else if ($guess > $number) {
        print 'Too high'
    }
    else {
        print 'You guessed it!'
        break
    }
}
print 'congrats'

Structure of this repository

This repository contains the following projects:

• RCaron: The language itself
• RCaron.Shell: The RCaron shell
• RCaron.LibrarySourceGenerator: A source generator for creating libraries
• RCaron.LibrarySourceGenerator.Attributes: Attributes for the source generator
• RCaron.AutoCompletion: Auto completion that powers the language server and the shell
• RCaron.LanguageServer: A Language Server Protocol implementation
• RCaron.Tests: Unit tests
• RCaron.FunLibrary: Experimental stuff
• RCaron.Benchmarks: Just a basic benchmark for checking between language versions
• RCaron.Jit: An expression tree compiler for the language, allowing for faster execution at the cost of a slower "dry" run
• RCaron.Jit.Tests: Unit tests for the JIT (uses RCaron.Tests)
• RCaron.Testing: Just some testing stuff
• Rcaron.Cli: A basic command line interface, this is not the main RCaron experience
