I tried to install Haskell Platform from the official website and they asked me to configure Chocolatey on my computer and then to run choco install haskell-dev refreshenv, so I did it and installed:
and now i have no idea how to get started with the Haskell and whether I've installed everything I needed, could somebody help me?
This looks like pretty much everything you need. It looks like you’re struggling a bit to understand what everything is for, so I’ll explain the purpose of each component:
ghc is the Glasgow Haskell Compiler a.k.a. GHC, which compiles your code to an executable. Also included in this package is ghci, the GHC interpreter a.k.a. GHCi, which you can use to interactively enter and execute code.haskell-dev appears to be an auxiliary package to get msys2 properly set up.msys2 is MSYS2, which provides an environment allowing access to Unix-like tools. You won’t need it for simple stuff, but it can be invaluable when trying to build some Haskell packages.cabal is the Haskell package manager. (Well, one Haskell package manager: the alternative is Stack, which is compatible with Cabal.) You’ll be using this to develop, build and install Haskell packages.As for ‘how to get started with Haskell’, this isn’t really the place to ask (maybe try Reddit /r/haskell), but off the top of my head I can think of http://learnyouahaskell.com/ and https://haskellbook.com/ as well-known resources for learning the basics. If you already know the basics and want to start learning more advanced features, try What I Wish I Knew When Learning Haskell.
