Common Lisp code

This collection comprises Common Lisp libraries and sample code specifically designed for Lispworks. Some of these libraries have been actively utilized in production systems, running continuously for over ten years.

MySQL Native Driver

Native driver for the MySQL database in Common Lisp. The word "native" here means that the code connects directly to the database through a socket without using C bindings or other foreign language bridges. The code requires no additional libraries, as everything needed is included in a single file. It works with MySQL 5.0 or higher and any version of LispWorks 8.0 or higher.

This library was my first piece of code ever written in Common Lisp and has since become the backbone of production systems driving warehouse operations and online shops.

Amazon SES

Interface to Amazon Simple Email Service (Amazon SES) to send text messages without requiring additional Lisp libraries. All the necessary Lisp code is included in a single file. The implementation depends on OpenSSL libraries and is compatible with any version of LispWorks 8.0 or higher. The code includes an SHA-256 implementation written in generic Common Lisp.

SQLite3 Driver

Foreign language interface to the SQLite Version 3 database in Common Lisp for LispWorks, requiring no additional Lisp libraries. All necessary code is contained within a single file. The code depends on the sqlite3 external dynamic library and works with any LispWorks version 8.0 or higher.

SHA-1

SHA-1 (Secure Hash Algorithm 1) and Hashed Message Authentication Code (HMAC) implementations in generic Common Lisp, not specific to LispWorks. They require no additional libraries; all the necessary code is included in one file.

MD5 Message Digest

An implementation of the MD5 message-digest algorithm and the Hashed Message Authentication Code (HMAC) using the MD5 algorithm, written in generic Common Lisp (not specific to LispWorks). It requires no additional libraries; all necessary code is included in one file.

2048 Game

The Common Lisp implementation of this simple game was developed to explore the graphics capabilities of LispWorks' CAPI for cross-platform drawing on both Windows and Linux systems.

Python code

MySQL Native Driver

This is a reimplementation of Common Lisp's native driver for MySQL, written in Python. I needed a database connection for some Python code and wanted something simple to deploy, so one evening I wrote this code. While it isn't a complete library, it includes all the necessary machinery to function as one. The code is fully functional.

Forth code

I've exclusively used RPN calculators since high school, so I never questioned why I should use Forth. It just clicked naturally, and has stayed with me ever since.

COM Interface

This interface to the Component Object Model (COM) was written in just 25 lines of code. I consider it one of the most elegant pieces of code I've ever written. The Component Object Model is inherently simple, yet in every programming language I've used — C++, C#, Delphi, and Common Lisp — it is often perceived as overly complicated. It shouldn’t be.

The snippet of COM interface code is extracted from a larger library designed to interface with Microsoft Outlook. The Forth code was written for SwiftForth 32-bit.

Calendar

Monthly and yearly text-based calendar with weeks starting on Monday. Forth code is compatible with SwiftForth for Linux 32/64-bit systems. The screenshot of the program.
