choco

This is a interpreter language whose host language is golang.

IMPORTANT This project is based on Writing An Interpreter In Go

what choco can do

let thresholdForAdult = 20;
let user = {
    "name": "Tom",
    "age": thresholdForAdult + 10
}

let userrole = if (user["age"] >= thresholdForAdult) {
                 return "ADULT"
               } else {
                 return "CHILD"
               }

let showNameIfAdult = fn(user) {
    if (userrole == "ADULT") {
        puts(user["name"])
    }
}

you can find more example in ./examples directory

(Off topic) why "choco"?

this lang is named after one of my dogs, and "ちょこ"っと使える(can be used a little in Japanese) sounds like "Choco".
