#42 | fixed | Result of foldAllP isn't forced. | ||
Description |
Report from Chris Reade:
That is why I expected this code to work without the explicit writeHeatMapBMP :: String -> Array U DIM2 Double -> IO() writeHeatMapBMP filename arr = do maxVal <- foldAllP max 0.0 arr minVal <- foldAllP min 0.0 arr arrImageOut <- minVal `seq` maxVal `seq` computeP $ R.map rgb8OfDouble $ R.map (rampColorHotToCold minVal maxVal) arr writeImageToBMP filename arrImageOut The implementation of foldAllP should ensure that the result is evaluated before it returns. |

#34 | fixed | Ambiguous show instance. | ||
Description |
Grigory Sarnitskiy reports: Hello! I'm using repa 2.1.1.5, so maybe this issue is gone already. Nevertheless, repa's Show instance is a bit ambiguous, e.g. show of Maybe (Array DIM1 Int) "Just Array (Z :. 1) [...]" Wouldn't it be better to have "Just (Array (Z :. 1) [...])" just like elsewhere in Haskell? For example show $ Just $ Just 5 "Just (Just 5)" |
