WIP: This page provides links to resources for learning Haskell and getting information about Haskell-related tools, libraries etc used in Decker.
## General Haskell resources
### Books
-["Get Programming with Haskell"](https://www.manning.com/books/get-programming-with-haskell): Great introductory book for programmers wanting to learn Haskell syntax and how to get started writing productive Haskell code without needing to learn how to program first.
-["Haskell Programming from first principles"](http://haskellbook.com/): Very extensive book (> 1000 pages) starting from the very beginning of learning how to program using Haskell.
-["Learn You a Haskell for Great Good"](http://learnyouahaskell.com/): Entertaining to read but slightly outdated. Not the best resource to actually learn writing code as it does not contain exercises.
### Other
-["The Haskell Tool Stack"](https://docs.haskellstack.org/en/stable/README/): `stack` is the Haskell build tool used in Decker
-["Hackage"](http://hackage.haskell.org/): The Haskell community's central package archive of open source software.
-["Haddock"](https://www.haskell.org/haddock/): A Haskell documentation tool
-["Hoogle"](https://www.haskell.org/hoogle/): Hoogle is a Haskell API search engine, which allows you to search many standard Haskell libraries by either function name, or by approximate type signature (also available as command line tool via Hackage)
- Haskell docsets are also available for [Dash](https://kapeli.com/dash)(macOS), [Zeal](https://zealdocs.org/)(Linux) or [Velocity](http://velocity.silverlakesoftware.com/)(Windows)
## Libraries used in Decker (links to hackage documentation)
- Pandoc:
- General Pandoc documentation page on hackage: http://hackage.haskell.org/package/pandoc
Types for representing a structured document (`Block`, `Inline` etc), defining the pandoc data structure, functions for building and manipulating pandoc documents (`walkM`, ...).
