Higher Level Concepts In The Lambda Calculus
Some Syntactic Sugar We are going to be talking about some pretty high level concepts in this post, like true and false and maybe even the natural numbers (although that might be too high level and need to be left to the next post). You’ve probably realised that the Lambda Calculus has no means of … Continue reading Higher Level Concepts In The Lambda Calculus
Computation With The World’s Smallest Programming Language
Update: The latest version of the lambda calculator has line editing and a command history. It’s more convenient than the version linked in the blog and is tagged 0.1.0. Note to the reader: much of this post is based on an article I found on the web called Lambda Calculus (part I). That article covers … Continue reading Computation With The World’s Smallest Programming Language
The World’s Smallest Programming Language
Update: The latest version of the lambda calculator has line editing and a command history. It’s more convenient than the version linked in the blog and is tagged 0.1.0. Introduction The world’s smallest programming language is probably the Lambda Calculus. The Lambda Calculus was invented by Alonzo Church in the 1930’s as a means of … Continue reading The World’s Smallest Programming Language
The Forth Protocol
In which I accidentally discover a performance enhancement I’m really not a fan of the massive switch statement at the heart of the execution loop, so I have decided to see if I can do something with virtual functions or closures on a WordList. The execute function would be reduced to running a particular function … Continue reading The Forth Protocol
