The goal of this project is to provide a fully-functioning implementation of the Bel language, proposed by Paul Graham. The main goal is not to provide performance; instead, it is supposed to be a didatic approach to implementing a Lisp interpreter.
The code here contained is also a study on how to build a Lisp interpreter from scratch in C. Given that Bel is so simple and is supposed to be a formalism before a commercial language, it seems like the perfect didatic resource to do so.
Here are some useful links with language resources:
This project was also implemented as a proper /book/, so it is supposed not only to be compiled, but also to be read. All the development was made in the ~believe-literate.org~ file, though the book was exported to LaTeX and the code was exported to a C source file.
This project was implemented as an experiment with literate programming, so it can be read in PDF form. Just check the ~believe-literate.pdf~ file, or check out ~believe-literate.tex~ to see a LaTeX export of the book.
Alternatively, most Git services are able to render Org files properly, so you can check ~believe-literate.org~ on your browser.
All the compilation steps are done through a ~Makefile~. You can refer to further information within the chapter /Tools and scripts/ on the book.
