How to write a toy interpreter

Ruby
1

Hi,

I was reading today this post [1], and i would like to write my own
toy interpreter. The simplest example possible (with or without ruby).

Can anyone recommend me some start points ? (URLs, tutorials, or books )

Thanks.

An excellent book for everything about language parsing and code
generation
is “Compilers: Principles, Techniques and Tools”

A toy interpreter is part of the test suite for Dhaka (a parser
generator -
http://dhaka.rubyforge.org). There’s even a page documenting the
interesting
bits:

The whole interpreter is about 300 lines of code.

Mushfeq.
