Haskell-Data-Analysis-Cookbook

That line of code was demonstrative. The actual book uses 'Data.Char.IsSpace' which properly handled it. "Returns True for any Unicode space character, and the control characters \t, \n, \r, \f, \v." Before you chastise them for not handling something, verify it. I'm not affiliated with the book but you probably deterred people from buying it. https://github.com/BinRoot/Haskell-Data-Analysis-Cookbook/bl...

This is a repost of a book we published in 2014. It's well reviewed, and the author kept the Github repo for the code up to date with feedback (https://github.com/BinRoot/Haskell-Data-Analysis-Cookbook). If anyone wants to try it, you can pick it up in the Packt sale currently for $10 @ packtpub.com

I like seeing more things come out helping people with data analysis in various languages, but this put me off: > isWhitespace x = elem x " \t\r\n" This is the kind of thing that makes me concerned about using this resource for real-world data. In real-world data you're going to get all kinds of crazy things coming in, and if you're assuming nobody will ever have something like a zero width non-breaking space, or a form feed, you're going to have a problem. It's the kind of thing I see with people starting out when dealing with data, similarly the punctuation detection here: https://github.com/BinRoot/Haskell-Data-Analysis-Cookbook/bl... If you rely on these things, you will have problems. Text is hard and weird and terribly more complicated than people usually expect. Does haskell have good libraries for dealing with the more awkward par
