Write a compiler for brainfunk
Write a compiler for brainfunk
About the Book
This book covers writing all the usual tools we use as software developers for a tiny language named brainfuck (sorry for the typo in the main title).
Presenting all the tools and keep the book small was possible because of the few features of the language.
The downside is that writing a program using this language is something I do not recommend to any of you.
But if you want to know what involves writing programming tools for developers, then brainfuck is a great language.
