Introduction

Bonzai is a generic purpose programming language that relies on a strong and non-taulerant typechecker to guarantee types and computations in your code. It compiles down to a custom bytecode with relatively good performance.

Features

• Strong typechecker: Throw errors for incompatible types, to ensure security when running your code.
• Datatypes as expressions: All datatypes are expressions, allowing for more flexibility in your code.
• Row polymorphism: Allows for dictionary-like structures with flexible keys.
• Bytecode compilation: Suitable for Unix-like systems, enabling almost multi-platform code running.

Example Code

A parallel HTTP server dispatcher example :

require "std:http"
require "std:foundation"
require "std:datatypes/json"

let thread = spawn HTTP::create(
  fn(req) => {
    let headers = req->get()

    match Header::from(headers) {
      case Some(Header(top, _, content)) => {
        let json = JSON::parse(content)
        let [method, path .. _] = String::split(top, " ")

        print("[$method] Received request on $path")

        req->send(JSON::stringify(json))

        true
      }

      case None => {
        print("Invalid JSON")
        req->send(JSON::stringify(
          JSON->Object([
            ("error", JSON->String("Invalid JSON")),
            ("status", JSON->String("400 Bad Request"))
          ])
        ))

        false
      }
    }
  },
  8000
)

print("Server started on port 8000")

thread.wait()

Building Bonzai

Prerequisites

• Haskell compiler: GHC 2021 is required to compile the code
• XMake: to compile the VM
• Python: to run the build script

1. Clone the Repository:

git clone https://github.com/bonzai-lang/bonzai.git
cd bonzai

2. Build the project:

python3 scripts/build.py

3. Set the environment variable:

export BONZAI_PATH="/path/to/bonzai"
export PATH="/path/to/bonzai/bin:$PATH"
