Haskell for Mac supports OS X Yosemite or above. Autosaving and automatic project versioning.Haskell binding to Apple's 2D animation and games framework SpriteKit.Add code and multimedia files to a Haskell project with drag'n'drop.Playground results can be text or images produced by the Rasterific, Diagrams, and Chart packages.Easy to explore type information and to observe the behaviour of you program as you change it.Interactive Haskell playgrounds evaluate your code as you type.Built-in Haskell editor with customisable themes, or you can use a separate text editor.They are convenient to learn functional programming, prototype Haskell code, interactively visualize data, and to create interactive animations. Haskell playgrounds support exploration and experimentation with code. It is a one-click install of a complete Haskell system, including Haskell compiler, editor, many libraries, and a novel form of interactive Haskell playgrounds. Haskell for Mac is an easy-to-use integrated programming environment for Haskell on OS X.
There are Mac OS X installers of the full Haskell Platform development environment. 7 Shipping Installable Haskell Applications.5 Installing libraries with external C bindings.3.4 Mac OS X 10.6 (Snow Leopard) and 10.7 (Lion).3.2 Mac OS X 10.9 (Mavericks), Mac OS X 10.8 (Mountain Lion) and Xcode 5.Or maybe it's just because a lot happens in 3 lines of code. or perhaps there'd be a nicer way to compose these functions. But somehow I don't feel happy about its readability. InsertMissing date acc = if M.member date acc then acc else M.insert date 0 acc Zeros cs = M.toList $ S.fold insertMissing (M.fromList cs) allDates Insert zero counts into date buckets that are missing a sample.ĪllDates = M.fold (flip (foldr (\(date,_) -> S.insert date))) S.empty m The code I use for filling the gaps with zero samples is as follows: import Data.Time (UTCTime) The same data with the gaps closed becomes: fromList ) I need to fill these gaps with zeros before I pass the data to the plotting library. You will note that the above "bar" series is missing a sample for. Data used for plotting data series 'foo' and 'bar' I have a map from tags to lists of (time,count) which I plot as a stacked graph: import Data.Time (UTCTime) I'm working around a bug/feature in a plotting library. I'm looking for tips on how to make my functional code easier to follow. My Haskell set/map/list folds often become terse and difficult to read.
