Hello. First I'd like to thank for great job c2hs is doing. However I find a few points where it could be better.
1. New marshallers. Sometimes pointer + defaults are not good enough.
Maybe something like
{#marshaller cname [into hname] in='hname[-*]' out='hname[-*]#}
would be helpful.
Possibly overriding default marshallers would also be helpful (for
example if string is encoded in UTF-8).
2. Most of the C2HS library can be done as default elements. What's the
point of defining cIntConv as fromIntegral? Why not simply not insert
fromIntegral or Prelude.fromIntegral?
3. I find that many times I'd like to insert a simply variable into
argument. So I find out that:
{#fun ... {
withNullPtr- `Ptr ...',
...
} -> ...#}
where withNullPtr f = f nullPtr
I guess that
{#fun ... {
nullPtr% `Ptr ...',
...
} -> ...#}
or similar or
{#fun ... {
($nullPtr)- `Ptr ...'
} -> ...#}
would be helpful (the second notation allows any arbitrary Haskell
function to be executed which is also usefult.
