Sankuru Blog:
A simple bytecode compiler with virtual machine, written in Php, for the EL language
December 30, 2011 @ 11:06:36

On the Sankuru blog there's a recent post looking at the construction of a simple bytecode compiler with a virtual machine as written in PHP (for Expression Language).

In my previous blog posts, I demonstrated how we can use the builtin PCRE library, to create a lexer in Php. I also showed how to use Bison-generated LALR1 parser tables in Php. In this blog post, I will re-use these lexing and parsing facilities to compile EL programs from within Php.

He uses his lexer/parser (available for download) in an example program that outputs some values and does some simple mathematical operations. There's sections detailing the Bison grammar used, execution stacks, callbacks and the bytecode it produces.
