That said, برای دیدن ادامه مطلب اینجا را کلیک کنید for the work that I do on a daily basis I’m a bit reserved about the offerings of dependently typed languages; having spent a fair bit of time investigating possible use cases for dependently typed numerical programming. There is much work in this space on both the engineering and research side; yet I’m quite confident with some changes that are coming in GHC 8.0 that this will converge on a nice tight solution. Specifically case expansion is a much loved feature that is still missing from our current ghc-mod tooling. The Haskell IDE Engine is a community effort to provide a universal IDE interface that abstracts over the common functionality needed to build future tooling. Vim integration with Haskell has never been easier and a lot of the problems around ghc-mod and syntax highlighting have been packaged up and managed by stack now by the haskell-vim-now package. Building simple things makes sense because it stands to reason developers will lose a lot of time refining a feature, only to be told the refinements were unnecessary weeks later. Although technically not a recent development, Idris has seen a lot of work in 2015. Idris is very promising foray into the next generation of dependently typed languages that actually aims for a full end-to-end compiler. The code generation is fairly natural mapping of Haskell lambda to Javascript functions, delegation to underlying Javascript builtins for primitive operations, and the usual dictionary passing translation for typeclasses. As of 2015 there are several new offerings for high level bindings, most of which offer an interesting new perspective on type-safe query generation. With the advent of type holes (at both the value and type level now) there exists are an interesting set of opportunities for providing Agda-like editor integration that is syntax and type aware. In 2016 when the languages evolves a modern type system I will give it another look. The type system is superset of Haskell 2010 and expressive enough that the full set of common functional programming idioms are expressible. In the past SQL has been a particularly sore spot in the Haskell ecosystem, although typically the low-level bindings are present the problem of building a easy to use, type-safe, database-agnostic, اینجا کلیک نمایید language-integrated query system that maps to Haskell data structures has been ongoing.
