What books would you like to see written on Scala?

[Yuvi Masory]

Hi everyone,

I've exchanged a few emails with Manning. They are interested to know what subjects the community is interested in having Scala books written on.

For example, would a Scala cookbook-style book be good? One on Akka? Etc.

Please add your suggestions. Since this is being discussed publicly all publishers will benefit equally from your answers.

I'd personally love a full book on Akka.

+1 on an Akka book, as well as Debasish's idea for "Effective Scala".

Carl-Eric

[Thomas Lockney]

I would love to see books covering the following topics (could be a complete book on each or some part of a larger work on something more broad):

* Akka (perhaps extending more broadly into distributed systems dev with Scala)

* Functional programming (preferably covering general FP concepts applied to Scala, the theoretic underpinnings and, perhaps, some coverage of Scalaz)

* As mentioned by Debasish, Effective Scala would be an great companion to the two Scala books currently in development at Manning

There are interesting books at manning like Debasish Ghosh Dsl in action, the Joshua Suereth  MEAP Scala in depth. I 'd really like a book about the philosophy of writing with actors from Carl Hewitt thougths to Scala/Akka implementations, through Erlang applications, with real world examples. To embrace Actor paradigm I have bought an Erlang book. Nice move, but some Scala/Akka stuff would be really welcome.

[Durgesh Mankekar]

If someone from O'Reilly is reading this, then a newer edition (for 2.9) of Programming Scala (by Dean Wampler / Alex Payne) would be great too, specially for newcomers.

[mansoor.ashraf]

I would like to a see a book on Scalaz Covering type classes,
Applicative functors, Monads and other FP topics. Also an Effective
Scala book would be great as well

[Dean Wampler]

Yea, I want to do that. I'm finishing another O'Reilly book now (Functional Programming for Java Developers) that comes out next week at OSCON. I'll talk to my editor about updating Programming Scala. I've already started working on updating the code examples.

[Xuefeng Wu]

I need Effective Scala such as Effective Java.

And I also need a Scala Lite? for  Software Engineer without mush programming experience and math knowledge.

The number of beginner is large and the learn cure of scala FP is high.

I think need a book or something  could fill the gap.

The most of developer is developing application but not framework, and without much math knowledge.

The book may should cute some scala feature and promote some code standard.

[Xuefeng Wu]

In a short, I need a book for beginner who don't have programming experience and math knowledge.

They would do work follow some example/standard/other engineer guide.

They would not design and develop framework, and may never read scala-user mail list.

here is my wishlist,

1) more functional oriented scala
2) more on generics including manifest and the new specialise annotation.
3) more on implicits for 2.8
3) monads,monads,monads (theory and practice); from identity monad to comprehension monad
4) delimited continuation, theory and practice. enough to start programming using continuation
5) compiler plugin, why should one write one and how.
6) how to use the above to write dsl
7) parallel collections made simple - when n where to use parallel and how, best practices.

Also a book that will assume that the reader is already use to some scala idioms, and do not need introduction to stuff like class, pattern matching,
closures etc....

[Josh Suereth]

Just wanted to state two things:

(1) Scala In Depth was initially titled Effective Scala.  You'll see a lot of this flavor in the book.   However, it became apparent that education in the type system and FP on Category theory (as seen in haskell) was needed.  Hence the move to Scala In Depth.  Hopefully you should find a bit of what you need there, or I've failed in my mission.
(2) Scala best practices are probably going to change (just slighty) over the course of the next year or two.  I'd say we can put together a good book, but something akin to Effective Java might be a year or two away....

Effective Java is a really good book. However, it benefited from Java being a mature programming language with a body of practical experience backing it, and from an author who had intimate knowledge of Java. It also is unashamedly the author's personal views. I'd agree with Josh that we are probably a little time away from having this depth of experience with Scala, although it is a book I'd buy tomorrow if it was available.

Matthew

[Debasish Ghosh]

I agree Scala idioms may change somewhat over the next couple of years. We can have multiple editions of Effective Scala (just like Effective Java) reflecting the changes. Lots of people are using Scala today. And they need this guidance today. The earlier we have such a book, better will be the code base that gets accumulated for tomorrow. And anyway if we start writing such a book today, it will take (almost) a year to complete.

Just my 2 cents ..

[Sonnenschein]

To become a widely used programming language, Scala needs to
effectively replace parts of the Java Enterprise world. Any book or
whitepaper on this topic suitable for it managers and software
architects would pave the way for this process. I would also expect
typesafe.com to provide such material.

 Functional programming for the imperative programmer

[Josh Suereth]

I guess what I'm saying is I tried to capture this in Scala IN Depth, but it's intermixed with some "Let's explain FP" and "Here's the nitty gritty on implicits".   Right now, best practices exists *and* certain areas of Scala need more in depth understanding so we can even describe best practices.  Hence the book, Scala In Depth.

So, if you want an Effective Scala book, please read Scala In Depth.   If it doesn't fit the bill 100%, I'll write another :)

Hi

 

I'm getting a List of Extractors like 

 

object eInt  {def unapply(s: String) = Some(s.toInt)} 

object eDbl {def unapply(s: String) = Some(s.toDouble)} 

...

 

val extrs = List(eInt, eDbl, eInt, eString, ...)

 

and data

 

val data = List("1", "2.0", "3", "foo", ...)

 

now I want to extract the corresponding list of Anys via

 

data zip extrs map {e =>

    e._1 match {case e._2(a) => a}

}

 

and getting

 

error: value _2 is not a case class constructor, nor does it have an unapply/unapplySeq method

 

How can I cure that?

 

Thanks in advance,

and I'm missing the book "Scala: Best Practice"

Your list of extractors is most likely being inferred as a List[Any].
Easiest way to remedy that would be to create a common trait for them:

trait StringExtractor[A] {
def unapply(s: String): Option[A]
}

then define them as:

object EInt extends StringExtractor[Int] {def unapply(s: String) =
Some(s.toInt)}
object EDbl extends StringExtractor[Double] {def unapply(s: String) =
Some(s.toDouble)}

That should make your extractor list a List[StringExtractor[Any]]

Then to do the actual extracting it may work with pattern matching as
you tried, but you might have to do it manually:

data zip extrs flatMap {e => e._2.unapply(e._1) }

which will give you a List[Any].

Well, if you don't mind Java syntax, O'Reilly is publishing my book, "Functional Programming for Java Developers" next week.

http://oreilly.com/catalog/9781449311032/

It's a short introduction, so experienced functional programmers won't find much that's new. It's aimed at the "imperative" Java programmer ;)

Hi Marc-Daniel,

> There are interesting books at manning like Debasish Ghosh Dsl in action, the Joshua Suereth MEAP Scala in depth. I 'd really like a book about the philosophy of writing with actors from Carl Hewitt thougths to Scala/Akka implementations, through Erlang applications, with real world examples. To embrace Actor paradigm I have bought an Erlang book. Nice move, but some Scala/Akka stuff would be really welcome.

This is exactly what we are aiming at with our book on actors ("Actors in Scala", Artima).

It starts with the philosophy behind actors, covers Scala's language support for programming with actors, and then continues with concrete examples written in Scala. It covers both the scala.actors package in Scala 2.8/2.9 as well as Akka's actors (Akka 2.0). There are larger examples on how to do MapReduce-style computations, graph processing, as well as the core of a cluster runtime system using remote actors.

While we cannot cover the entire Akka API (which still has to stabilize in some areas), the book should get you up to speed, in a way that is complementary to Akka's excellent online documentation.

Cheers,
Philipp

I'd rather they waited a bit, actually... :-) There are a few books in
the pipeline:

Scala in Depth by Josh Suereth
Lift in Action by Tim Perret
the actors book by Phillip Haller, I don't recall it's name
the mysterious book about functional programming in Scala -- by Runar?
Tony? Not sure.

If they all accomplish what they set out to do, they'll cover most of
what's needed right now. If something is missing, then I'd target what
they miss. Personally, I think more books like Scala in Depth will be
needed, however well Josh might have done his job. Unfortunately,
finding an author that is _really_ up to it might be very hard,
because most of us are simply not using Scala on large scale projects
long enough.

I don't know how the functional programing book is going, but I think
there's market for more books on learning functional programming with
Scala. Then again, I'm biased.

I agree that a short book on SBT would be really nice, since SBT is
now such an important and essential element of the Scala ecosystem. +1
on that.

Another book that I'd enjoy would be Testing with Scala, covering
Scalatest, Specs 1 and 2 and Scalacheck. It can have additional
chapters covering testing on Lift, that Scala mocking library (sorry,
can't recall the name right now), Scala's partest system or minor
testing libraries, as "extras". It is not that these frameworks are
particularly hard to learn and use, but having a book about something
lowers the entry barriers to that.

The nice thing about a book like that would be each other would only have to write a few chapters, which could streamline the process from the publisher's perspective. I'd like to see a testing book too! Maybe if that's not large enough a subject it could be embedded in a larger book on Scala software engineering that also covers sbt and some other topics.

I hope so. On the other hand, the first three are already completed,
just undergoing editing. The functional programming one I wouldn't
have mentioned if Tony was not so emphatic about it. :-) I'm just
trying to focus on thing that are almost out there. I should have left
the FP one out.

[Bill Venners]

Hi Francois and y'all,

Yup. Monadic Design Patterns by Greg Meredith is in the pipeline.

Actors in Scala is the name of Philipp and Frank's book. Meeting with
Philipp and the editor on that tonight in fact. Actors will be the
next book we publish, currently scrambling to get it out end of
September.

The name of the Scala mocking framework is Borachio (by Paul Butcher).

Dick Wall and I are thinking of writing a pair of Effective Scala
books, one for library users and the other for library designers. I
haven't seen what Josh has done yet with Scala in Depth, but I'm
pretty sure given his descriptions that it would be different from
what Dick and I have in mind. We're want to write them with lots of
community feedback as we go, because these should document what the
community has learned over time.
