I\'m trying to figure out how to use StateT to combine two State state transformers based o开发者_运维问答n a comment on my Scalaz state monad examples answer.
Given a signature like this one or that one: def foo[A, F[_]](implicit mon: Monoid[F[A]], pr: Pure[F]): F[A]
I want to call Scalaz\'s pure method to put a value into the State monad. The following works: type IntState[A] = State[Int, A]
I\'ve found this pattern quite a few times in my code: if (doIt) object.callAMethod else object I\'m wondering if there could be a syntactically more pleasing way to write the code above, especiall
Given a sequence of eithers开发者_Python百科 Seq[Either[String,A]] with Left being an error message. I want to obtain an Either[String,Seq[A]] where I get a Right (which will be a Seq[A]), if all elem
I\'m currently working on a small project (< 10k loc) which is mainly pure but relies on mutable optimizations mainly based on iterators and some data-structure reuse for heavy-duty calculations.
I imagine something like this: def combine[A, B, C](f: (A, B) => C): (M[A], M[B]) => M[C] while M would be Function0. Is this possi开发者_运维技巧ble in scalaz?import scalaz._; import Scalaz.
I am trying to port a significant amount of code written in python with twisted to scala, and I\'m looking for opinions on what framework combination to choose.
I am currently playing with Scalaz non-blocking futures aka. Promises. I am struggling to make the following function tail-recursive:
We\'re using scalaz validation trait in our project to validate HTTP parameters. The common case is taking few validate开发者_开发问答d values and performing neccessary action only if all of them are
