Much of + the material it contains is well-explained, from a tutorial point of view, by + <http://hackage.haskell.org/package/lens-tutorial lens-tutorial> It is independent, + self-standing and readily intelligible apart from any darker + more general system of combinators that might attempt to extend it. Much + of it ought to be in the Prelude. + + Convenient import of the elementary combinators from @lens-family@, + however, a little complicated. The idea of this trivial module, then, is just to make a sort of + low-powered, minimal-dependency, @lens-family@ equivalent of + the 800 lb gorilla of lens library imports: + + > import Control.Lens + + namely, the light-weight and elegant: + + > import Lens.Simple + + Check it out, it's even one character shorter! + + The material in <http://hackage.haskell.org/package/lens-tutorial lens-tutorial> + will work fine if you make this substitution in the underlying + <http://hackage.haskell.org/package/lens-tutorial-1.0.0/docs/src/Control-Lens-Tutorial.html source> + and follow along as prompted. + + As another illustration of the simplicity of the + fundamental van Laarhoven-O'Connor lens combinators - and their homogeneity with + @Control.Lens@ - note that the gloss + <https://github.com/michaelt/lens-family-simple/blob/master/examples/Pong.hs pong example> + from the @lens@ library examples directory - which continues to be + among the best introductory lens tutorials precisely by saying nothing - + requires only this abbreviating change of imports. + + If you make that program more complicated, + you might of course end up needing + the more sophisticated material in @Control.Lens@ and + its immense mass of dependencies.
