Thanks to the hard work ! Do you plan to sell hardcopy of it, or only pdf/epub ? Regards, Romain Le 2016-01-12 00:20, Darren Grant a écrit :

That is a healthy sum of work! Been keeping tabs and looking forward to the final product. Still have that spot on the shelf at home, and increasing rationale for the office.

Cheers, Darren

I'd been reticent in the past to announce the book on the mailing list, but it's pretty comprehensive now and we have enough ecstatic readers learning Haskell with it that I thought I'd share what we've been up to.

We're writing this Haskell book (http://haskellbook.com/ [2]) because many have found learning Haskell to be difficult and it doesn't have to be. We have a strong focus on writing it to be a book for learning and teaching - it's not just a reference or review of topics. Particularly, we strive to make the book suitable for self-learners. We think Haskell is a really nice language and learning Haskell should be as nice as using it is.

The new release puts the book at 26 chapters and 1,156 pages. You can track our progress here: http://haskellbook.com/progress.html [3]

The latest release included parser combinators, composing types, and monad transformers.

My coauthor Julie Moronuki has never programmed before learning Haskell to work with me on this book. She has written about using the book to teach her 10 year old son as well - https://superginbaby.wordpress.com/2015/04/08/teaching-haskell-to-a-10-year-... [4]

Julie has also written about learning Haskell more generally - https://superginbaby.wordpress.com/2015/05/30/learning-haskell-the-hard-way/ [5]

If you've been reading the book, please speak up and share your thoughts. We have some reader feedback on the site at http://haskellbook.com/feedback.html [6]

We'll be looking for a press to do a print run of the book soon as it's about 80% done. If anyone has any pointers or recommendations on whom to work with, particularly university presses, please email me.

Cheers everyone, Chris Allen

Hello, I never wrote that i consider this book "a bad thing", that would not make any sense. I expressively wrote the contrary in order to avoid misunderstandings, but that was not enough. Let me state it clearly: this book seems to have all the features to become a milestone for the Haskell community, and a reference for future users. It is getting a lot of interest and enthusiasm, and this is great! While more and more people will approach Haskell starting from Chris' book's pages, i hope that beginners will still be pointed to existing Haskell resources maintained by the community, like i was in the past. I was delighted by finding the quality and variety of knowledge in Haskell wikis. I was pointed to papers, i have got used to be exposed to the bare code of core libraries. I thought about the types and the source. I enjoyed my journey through the often blamed existing Haskell documentation, and i hope that people will keep getting lost into it and be passionate about it. Here are some important values i see in the docs coming from the community: * they are communitary - for me this is invaluable. they are an effort we do together, the result of a complex process. we can all try to contribute if we are not satisfied, and beginner's input is precious * they are public, free, not affiliated with any specific company * they are succinct - this always motivated me. i can read and forget 100 explanations about monads, but the type class in itself will always challenge me for its simplicity. one could write the core formulae in a small notebook and keep studying on it for weeks * they are open ended and diverse - this leaves room for criticism and evolution. often, the Haskell guide for something is a paper about the theory of it I think that i received a lot studying Haskell through this community-contributed material, i just want that we keep considering this a viable path, even after the valuable work from Chris will become the common ground for most of us. I want to avoid that in the future, when somebody comes to #haskell with a question, the easy answer would be "go read the 1000 pages and then we can chat". Anyway, from the feedback i have got i realise that there are a lot of strong feelings about this, more than i expected. What moves around this book are all good news for the Haskell community, and i admire how Chris and Julie were able to convey so much content and experience through it. I just wanted to express a different path to learning. I am sorry if my few words, a bit too abstract and cold in their tone, were preceived as gratuitous criticism.

Hello,

Can you explain your point a bit more ? How can more learning material can be a bad thing ?

I have bought nearly every books regarding haskell but for now every single one fall into those 3 categories.

- *Outdated* -> Real World Haskell, Programming in Haskell - *Too* *specific* -> Parallel and Concurrent Programming in Haskell, Haskell Data Analysis Cookbook - *Only* *for* *beginners* -> Learn you a haskell for great good, Thinking Functionally with Haskell, Beginning Haskell: A Project-Based Approach

I plan to buy "*Haskell Design Patterns*" and I have great hope for this one, but for now I think when learning haskell there is a missing step after being intermediate. My only good ressources to advance in haskell were the haskell wikibook (great stuff) https://en.wikibooks.org/wiki/Haskell, and blogposts where you can find more about traversable, foldable, generics, Free monads, GADTS, Template Haskells, comonads, lens, how to handle exceptions, ...

Those topics are not uncomonn in daily haskell programming, but are not present in learning materials. If this book can cover all of this, I will gladly accept it as a classical to have in your bookshelf.

As I am not very sure about why you are not entousiastics about this one, can you please explain how this book approch differs from the others and why it will impact negatively the actual ecosystem ?

Regards, Romain

Hello Chris and thanks for your effort in making Haskell more understandable to everyone. I hope that you will be open to an opinion which differs from the many enthusiastic comments you usually receive.

I do not want to sound grumpy, but i need to say that i am not ecstatic about the idea of this book, so i hope that it will not become a sort of mandatory reference for the Haskell community.

I do not consider the book and its research effort a bad thing, but i value existing resources and processes used by the Haskell community to document the language and the related theory. I don't think that getting into the details is useful here, i just want to mention that someone might be not interested in this project, and i hope that the choice not to read the book will be respected in all Haskell's public fora.

I sincerely hope not to start a flame. You do not have to convince me, i might buy the book tomorrow. I just want to mention the risk to consider this very extensive and comprehensive work as the *only* or the *best* way to learn Haskell. This would take some precious diversity away from us.

I hope that most people will understand the spirit of this remark.

Cheers, Francesco Occhipinti
