kaze 風

A basic tree-walk interpreter for Kaze, a simple interpreted programming language. Based on everyone's favorite interpreted learning-language Lox.

I created this to learn some basic things about programming language development. Kaze is nothing more than a simple toy language, and not intended for any real world use.

quickstart

Pass in a Kaze source file to the interpreter:

kaze program.kaze

Or fire up a REPL by invoking the interpreter without any args:

kaze

vscode extension

This repo includes a VSCode extension that provides syntax highlighting for the language! To use it, simply move the folder into your .vscode/extensions/ directory in your home folder, which is ~ in Linux and C:\Users\<username> in Windows.

examples

hello, world

print("hello, world!\n")

square root

fun sqrt <- x begin
    var z = 1

    for var i = 0; i <= 10; i = i + 1 do
        z = z - ( ( z * z - x ) / (2 * z) )

    return z
end

print(sqrt(36)) //=> 6

See more examples in /examples/.

building

You need the following to build Kaze:

• crystal: The language in which the interpreter is written.
• just: A command runner with syntax similar to make, used as the build tool. Note that on Windows, you'll need a sh like Git Bash to use it.

Run the following to build a development build for Kaze!

git clone https://www.github.com/pes18fan/kaze.git
cd kaze
just

The build will be produced as bin/debug/kaze. To produce a release build as bin/release/kaze, run:

just r
