Woah... I intended this thread for *what* we want to put in the file format to allow one to easily assign relationships between and characteristics of elements. I was trying to shift the focus away from awk, ruby, other program's file formats. I re-submit my original list:First grow up, you are the one crying.... And here is the solution for making the version control with git understand a zipped pcb file. http://the-gay-bar.com/2010/06/23/managing-zip-based-file-formats-in-git/ In summary you tell git that to diff the file it needs to me unzipped first.

1) Better angle support: include rotation (in degrees, rotation/translation matrix, whatever) as a location argument instead of altering the pad/pin/silk/refdes/whatever location data separately 2) Footprint re-use: reduce file size by having components refer to a 'base' component with XYRS information, make component tweaking easier. Say you wanted to change all your 0603 resistors - it's easier to change the fundamental component, rather than the present case of to modifying individual components in all of their rotations. 3) Connectivity information: include the connection information between line segments, similar to (but not necessarily exactly!) SVG format, where multiple points and arcs can be included in one line. 4) DRC re-use: refer to a 'base' DRC rule, rather than re-describing the DRC at every instance. DRC rules could be arbitrarily complex or simple, e.g. elements in DRC class '250V' must have a 0.050" clearance from class '5V', but can have 0.010" clearance within '250V', or something along the lines of the 'skinny, normal, fat, power' we have in place now. 5) Ability to lock any portion of the location coordinate, either in absolute or relative to another entity (line segment locked to pin/pad, components locked to the same Y coordinate, etc) - rather than just specifying an absolute coordinate.
