Scrapile

A somewhat fully-fleged rust-like programming language that, surprisingly, compiles to scratch

Guide

How to install

Make sure you have a rust toolchain of your liking installed and then run:

cargo install scrapile

Otherwise, if building it yourself isn't an option (rust toolchain isn't installed). You can download pre-built binaries for linux-gnu, linux-musl and windows in the releases section and then add it to your PATH environemnt variable.

How to use it

To compile a scrapile project:

• scrapile <source-code>.srpl <output_path>.sb3
• then simply upload the resulting file to scratch

Basic Hello World

1. First create a new scrapile project with the contents:

main { // the program starts executing at the main block
  println!("hello, world!"); // 'println' is a builtin function and "hello, world" is it's argument
}

2. Then run the command scrapile <source-code>.srpl <output_path>.sb3 to compile the source code.
3. After that, you can upload the resulting .sb3 file to scratch by opening their website, creating a new empty project, opening the file tab and hitting 'Load from your computer'.

4. Then, once the project is imported, simply hit the green flag and "hello, world" should be printed to the console.

Other examples

Other examples can be found in the examples directory and include:

• examples/showcase.srpl which showcases all the language's features.
• a simple benchmark (examples/benchmark.srpl) for the language's speed
• a simple brainfuck interpreter examples/brainfuck.srpl
