A Better Binary File Generator DSL in Ruby

September 13th, 2008 | Category: Programming, Ruby

In Creating a Binary File Using a Ruby DSL I did a very small example of using a ruby DSL to generate complex binary files without having to use C or a hexeditor. I’ve beefed it up significantly since then so here is the updated version of h2b.irb.

Boost Spirit Part I (Validating Against a Grammar)

July 01st, 2008 | Category: C++, Programming

I haven’t done a post in a while, but I thought the boost spirit library was worth an entry.

Spirit makes it so easy to specify and use a grammar that you should never hand write even the most trivial parser again.

The full code for this example can be found here.
