Tender

Tender is a freeware programming language specially designed for image processing, 2D graphics, scripting, and more!

Overview

Tender is compiled and executed as bytecode on a stack-based VM, which is written in native Golang.

Features

• Simple and highly readable syntax
• Can be compiled into bytecode
• Supports rich built-in modules
• Specially designed for 2D graphics

Quick Start

1. Install Tender on your machine.
2. Copy the sample code below:

// Basic example
str1 := "hello"
str2 := "world"

println(str1 + " " + str2)

// Example of canvas drawing (similar to JS Canvas)
import "canvas"
	
var ctx = canvas.new_context(100, 100)
ctx.hex("#0f0")
ctx.dash(4, 2)
ctx.rect(25, 25, 50, 50)
ctx.stroke()

ctx.save_png("out.png")

3. Save your code as hello.td (must use .td as the extension).
4. Run your script using this command:

tender hello.td

Installation

1. Download this repository.
2. Run the install.sh script to install Tender on your system.

Windows (Manual Installation)

1. Download the tender.exe binary based on your machine from the bin/os_arch directory and the pkg directory from pkg.
2. Copy the tender.exe and pkg directory to your desired location as follows:
