Documentation - Harding Smalltalk

Getting Started

Installation

git clone https://github.com/gokr/harding.git
cd harding
nimble harding

# Optional install
nimble install_harding

Requires Nim 2.2.6 or later.

Quick Start

harding
harding script.hrd
harding -e "3 + 4"
harding --ast script.hrd
harding --loglevel DEBUG script.hrd

Use the interpreter for interactive work and Granite for native builds.

Granite Compiler

granite compile myprogram.hrd -o myprogram
granite build myprogram.hrd --release
granite run myprogram.hrd

Compile Harding code to standalone native binaries.

Where To Start

Core Language

Web And APIs

MummyX is Harding's current web server path: a fast scalable native multithreaded HTTP server, with Harding handlers executed through the interpreter's green-process model.

Example Code

Hello World

"Hello, World!" println

Simple Class

| c |
Counter := Object derive: #(count)
Counter>>initialize [ count := 0 ]
Counter>>value [ ^ count ]
Counter>>increment [ ^ count := count + 1 ]

c := Counter new.
c initialize.
c increment.
c value println

Resumable Exception

result := [
    10 // 0
] on: DivisionByZero do: [:ex |
    ex resume: 0
].

result println

Web Route

Harding load: "lib/mummyx/Bootstrap.hrd".
Server := HttpServer new.
Router := Router new.
Router get: "/" do: [:req |
    req respondHtml: "<h1>Hello</h1>"
].
Server router: Router.
Server serveForever: 8080.
