BlockIt

BlockIt is a simple Python framework designed to enable you to block parse your code into nested blocks. That doesn't sound terribly exciting, but each type of block is user defined, inheriting many useful methods from the parent Block class.

The methods allow you to do such things as create dependencies between blocks, modify blocks based on state parameters; dynamically modifying the final realization of the block. In a nutshell, it allows you to create a fairly sophisticated pre-processor, more powerful than straight-up macros (we have the power of Python at our disposal here).

The framework at its base defines a line scanner, a block parser and a symbol table used to globally store the blocks.
