A Simple (Custom) List Interpreter

A Simple (Custom) Lisp Interpreter

SCLI (A Simple (Custom) Lisp Interpreter) is a custom Lisp interpreter built in Python 2.7.x. It is meant to follow the language I developed that is an offshoot of Lisp. For more information you can head over to sv4u.github.io/scli-interpreter

Motivation

I have been interested in creating a programming language for the past year. So, I decided to read a bunch of manuals and then one day I finally tried writing one. This is the outcome of that day.

Releases

Currently, we have the alpha release here: github.com/sv4u/scli-interpreter/releases/tag/alpha

Install

To install, clone the repository into any directory you wish. Then, add that directory to your PATH so that you can execute scli from anywhere.

TODO

• Create an executable version of SCLI.py
• Add more default mathematical functions to the SCLI language
  • This was completed by adding the mathematics library
• Create a more user friendly interface for programming (a portable GUI)
• Create full flegded documentation
  • This documentation is only going to grow as features are added
• Add a Strings, Equation Solving, and Statistics Library

Mathematical Functions Library - DONE

This language is meant to be mathematics heavy. Since I am quite interested in computer science research, SCLI is primarily a research language. Currently the list of mathematical functions to implement are:

Function	Description	Status
Modular exponentiation	A simple x^y mod z operator	Done
Square Root	A simple square root operator	Done (with added nroot operator)
Ceiling and Floor	ceil(x) and floor(x)	Done
Absolute Value	abs(x)	Done
Logarithms	log(x) of multiple bases	Done (three types of logs: base e, 2, and n)

String Functions Library - DONE

The functions to add to this library are:

Function	Description	Status
String Concatenation	Concatenate two strings	Done
Substring	Substring between two values	Done
Character At	Finds the specific character at an index	Done
Length	Get the length of a specific string	Done
Split	Split a string on a regular expression	Done

Equation Solving Library - STARTED

The functions to be added to this library are:

Function	Description	Status
Linear Solver	Solves a linear equation	Done
Quadratic Solver	Solves a quadratic equation	Done
Cubic Solver	Solves a cubic equation	Done
Exponential Solver	Solves an exponential equation	Not started
Logarithmic Solver	Solves a logarithmic equation	Not started
Polynomial Solver	Solves a polynomial equation	Deemed Not Possible
Derivative Calculator	Calculates derivative	Not started
Integral Calculator	Calculate integral	Not started
Polynomial Factoring	Factors a polynomial expression	Not started

Statistic Analysis Library - NOT STARTED

Some basic statistic analysis functions to be added are:

Function	Description	Status
Standard T-test	Computes a standard T-test	Not started
Z-score Calculator	Computes a Z-score	Not started
ANNOVA Calculator	Computes an ANNOVA	Not started
Multiple Distribution Calculator	Calculates multiple discributions	Not started

SCLI Editor

Similarly to how Python is bundled with IDLE, I would like to create a IDE for SCLI. This is currently the most long term goal as it will take the longest about of time.

Documentation

Adding a documentation to SCLI for learning how to use it and how it is extremely similar to Lisp would not only help me but also new users.
