Symmetry groups broken on current Mac version.

Let the developers know what you think of the software and what can be done to either improve the CFDG language or the Context Free program.

Symmetry groups broken on current Mac version.

Post by kipling »

Looking at the latest "code golf" I thought I'd give it a go.

Current gallery code gives:

Parse error - pmg symmetry mirror axis argument must be 2 or 3
Context Free Version 3.0.8 (40) on Mac. 8-(

I did a bit of poking, and it looks like axis 0 in pmg symmetry on a mac is broken. Also the transformations in the wallpaper groups that do work seem strange. I don't have time to do much poking around just now, but will come back to it.

On the code golf thing, the good news is that I think you may be able to shave a few bytes off. You only need to specify half the shape, so

Code: Select all

path d{ARCTO(1,1,-1)ARCTO(0,2,1)}
and get the symmetry to fill in the other half.

Hand-coding a symmetry group works:

Code: Select all

CF::Symmetry=[],[f 90],[f 0],[r 180],[x 2 y 2],[x 2 y 2 f 90],[x 2 y 2 f 0],[x 2 y 2 r 180]
but the built-in symmetry groups seem to be doing really strange things.

Also put "startshape d" at the end to save a space char.

Dang. I didn't notice that because the issue is fixed in my development build. I have version 3.0.8 in my Application folder but my mac always chooses my developer builds unless I go to the Finder and explicitly run the v3.0.8 binary.

I was going to hold off on Context Free v3.0.9 until Microsoft releases the final build of Visual Studio 2015. But I guess the VS2015 release candidate is solid enough.

I have also migrated to Github here since Google Code is going away.
