ligo

ligo - scheme like language interpreter in golang

Introduction

ligo is implemented as a subset of lisp language with some changes in syntax. The syntax and usage is described in the documentation included in the doc folder.

Building

• First of all fetch all the packages without installing.

  go get -d github.com/aki237/ligo
  

• cd into the project directory

  cd $GOPATH/src/github.com/aki237/ligo
  

• Build the interpreter

  go install ./cmd/ligo
  

• Build the ligo plugin packages

  cd $GOPATH/src/github.com/aki237/ligo/packages/
  ./build.sh
  

  This installs the ligo plugins in $HOME/ligo

The ligo interpreter is installed in your $GOPATH/bin.

Usage

A commandline call without any arguments starts a interactive interpreter session. In that process it also initializes a interpreter by running a start script from the file $HOME/.ligorc (like .bashrc, in case of bash). Any argument passed is treated as a file and executes the contents in the file.

Simple Example

Simple example to get an input from the shell and

;; include all the required libraries
(require "base")

(printf "Hello %s!!" (input "Enter your name :"))

The bare interpreter has no functionalities (not even basic functionalities). The "base" package includes all the bare minimum functionality.

Extending the interpreter

Writing packages for the interpreter in Go is very simple and is discussed in this file.
