Build Status

Haskell NetCDF library: as well as conventional low-level FFI bindings to the functions in the NetCDF library (in the Data.NetCDF.Raw modules), hnetcdf provides a higher-level Haskell interface (currently only for reading data). This higher-level interface aims to provide a "container polymorphic" view of NetCDF data allowing NetCDF variables to be read into Storable Vectors and Repa arrays easily.

For example:

import Data.NetCDF
import Foreign.C
import qualified Data.Vector.Storable as SV
...
type SVRet = IO (Either NcError (SV.Vector a))
...
  enc <- openFile "tst.nc" ReadMode
  case enc of
    Right nc -> do
      eval <- get nc "varname" :: SVRet CDouble
      ...

gets the full contents of a NetCDF variable as a Storable Vector, while the following code reads the same variable (assumed to be three-dimensional) into a Repa array:

import Data.NetCDF
import Foreign.C
import qualified Data.Array.Repa as R
import qualified Data.Array.Repa.Eval as RE
import Data.Array.Repa.Repr.ForeignPtr (F)
...
type RepaRet3 a = IO (Either NcError (R.Array F R.DIM3 a))
...
  enc <- openFile "tst.nc" ReadMode
  case enc of
    Right nc -> do
      eval <- get nc "varname" :: RepaRet3 CDouble
      ...
Something went wrong with that request. Please try again.
