These two modules failed to generate much interest in incorporating them into 
Phobos, but I'm still rather proud of them :-)

Here they are:

◦sargon.lz77 - algorithms to compress and expand with LZ77 compression
algorithm

◦sargon.halffloat - IEEE 754 half-precision binary floating point format
binary16

I'll be adding more in the future.

how about you take the time to add a complete set of window 
headers before more people loose customers or their reputation?

Everything is in the lib file... it takes 30 second to copy and 
convert the import header from MSDN. I mean: your attack is not 
relevant. By the way additional imports could be added by PR by 
anyone tough I'm not sure if the DM team accept 3rd party PR (?).

Very cool that you decided to do this!

code.dlang.org has become a real thing really fast, I love that it has
grown so much.


 I'll be adding more in the future.


Sweet, looking forward to it!

So am I, the halffloat is much faster than any other 
implementation I've seen. The fast path for the conversion 
functions involves only a few machine instructions.

I had an extra speedup for it that made it optimal, but it 
requires a language primitive to dump excess hidden precision. We 
still need this, it is a fundamental operation (C tries to do it 
implicitly using "sequence points", but they don't actually work 
properly).

The intrinsics _mm_cvtph_ps and _mm_cvtps_ph converts 4 
floats/halffloats with a latency of 4 clock cycles and a 
throughput of 1 per cycle on Haswell.
