There are currently four libraries in the snapshot: DSP, Matrix, Poly, and Stat. I would like to add these to the official namespace, and would like to know where they should live.
Would you like to submit a proposal - or does the library snapshot you posted constitute a proposal? Would anyone else interested in DSPs care to comment on possible names for these libraries? In the current hierarchy design we have: Numeric DSP FastFourierTransform Noise Oscillator but given the size of your DSP library, perhaps moving it to the top level would be justified? The other question to ask is whether this is will be *the* DSP library, or whether there are other competing designs. If there are multiple designs, then the pattern we usually follow is to do something similar to the Text.PrettyPrint hierarchy, where we have Text.PrettyPrint.HughesPJ, Text.PrettyPrint.Wadler and so on.
Everything is GPL. I don't really care one way or another about this, but there is some code that I don't claim copyright to, and some derived code that inherits the GPL. In particular, MT19932.hs and Roots.hs have different copyright holders, and the original code was GPL. FFT.hs, FFTHard.hs, and PFA.hs have some derived code, so they have to inherit the GPL. I have to consult with the author, but IIRCookbook.lhs is a derived work, and I have a feeling that the license on this will be PD.
There is no problem with GPL code, but we must be careful with dependencies. Any code (library or otherwise) which depends on your library will potentially be required to be GPL'd too, so the license needs to be prominently displayed. Cheers, Simon
