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
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.
Currently, we have the alpha release here: github.com/sv4u/scli-interpreter/releases/tag/alpha
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.
- 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
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) |
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 |
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 |
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 |
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.
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.
If you are interested in seeing this project grow or helping me, feel free to contact me at [email protected]. I'm always looking for help.
