Introduction

Eclisp is a Lisp dialect that focuses on minimalism, simplicity, and clarity. Its design decisions are guided by the following mantras:

• Need for speed. Performance is a priority.
• Close to metal. There is less between you and vanilla Lisp by design. That means less to work around when you tinker.
• Different is good. Eclisp occasionally deviates from the original Lisp in favour of building a better, more modern language.
• The smaller the better. With the binary coming in at 121kb, and only about a thousand lines of code, Eclisp's core is tiny, without compromising on delivering a full-fledged, functional programming language.

Prerequisites

• a C compiler (GNU C Compiler v12.2+ is recommended)
• Git v2.23+

Install

Only GNU/Linux systems are supported.

language core

• clone the repository

git clone https://github.com/samarthkulshrestha/eclisp.git ~/.eclisp

• compile the code

cd ~/.eclisp/src
cc -std=c99 -Wall eclisp.c lib/mpc.c -ledit -lm -o eclisp

• make sure the binary is executable

chmod +x ./eclisp

• move the binary to somewhere in your shell's $PATH

mv ./eclisp ~/.local/bin/

standard library

• move the standard library file to library location

cd ~/.eclisp/src
sudo cp std.eclp /lib/

• set the environment variable for stdlib's location. add the following line to your shell's configuration file (.bashrc or .zshrc).

export ECLISP_ROOT="/lib"

Run

• running eclisp in the terminal launches the interactive prompt
