Re: Is this rdmd bug or my fault ?

Can anybody explain: Is dependencies file produced from command: dmd -deps=moduleA.deps moduleA.d must contains mention of moduleC? Is dependencies file produced reccursively? Thanks.

Convert some ints into a byte array without allocations?

I'm trying to make a fast little function that'll give me a random looking (but deterministic) value from an x,y position on a grid. I'm just going to run each co-ord that I need through an FNV-1a hash function as an array of bytes since that seems like a fast and easy way to go. I'm going to
