Hussar

A small programming language (very much under development).

Getting StartedUsageContributingPlanned FeaturesVersioningLicense

What's this?

This is my implementation of the Monkey interpreter in Go, based on Thorsten Ball's Writing an Interpreter in Go with my own changes, extensions and improvements. There are a lot of big changes planned, so this will probably divert a lot from the original project.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development, as well as normal use of the Hussar tools.

Prerequisites

To install Hussar for development, you need Go on your local machine. For instructions on how to install Go for your OS, follow the guide on their website.

Installing

For normal usage, you can install Hussar using Homebrew like this:

$ brew install hussar-lang/tap/hussar

Alternatively, you can download a copy from the releases.

For Development

The simplest method to download this project for development is with go get. Simply run go get github.com/hussar-lang/hussar in your terminal of choice, and the project will be downloaded to your Go path.

An alternative method is to clone the project from this repository directly. You can do this by running git clone git@github.com:hussar-lang/hussar. For the Go imports to work correctly without change, you will need to place the downloaded project in $GOPATH/src/github.com/hussar-lang/hussar. Once you're inside the project directory, you may have to run go get ./... to fetch any dependencies.

Usage

You can run scripts with the run subcommand, while passing in the script in question.

$ hussar run file.hss

Another option is to simply call the Hussar command without any subcommands, which will start the interactive mode (or REPL) like so:

$ hussar

Once in the interactive mode, you can run code and get the result returned. You can exit this mode by calling exit(0) or by pressing control-c in your terminal.

For more information about the tooling and which commands are available to you, you can run the env subcommand:

$ hussar env
arch:  amd64
os:    darwin
bin:   hussar
gc:    go1.12
vers:  0.4.0
