Syntax Highlighting Haskell

I was unhappy with the Haskell scripts that are shipped with vim, therefore I decided to make my own based on [idris-vim][].

I hope you find this useful.

Features

• Covers a broader spectrum of keywords
• Highlighting for new features like type families, pattern synonyms, arrow syntax, recursive do, role annotations, QuasiQuotation
• More contextual highlighting (e.g. highlight 'as' or 'family' only in appropriate places)
• Smarter indentation
• UnicodeSyntax extension support
• HexFloatLiterals extension support
• Special highlight Boolean Ordering syntax
• Highlight return, pure
• Highlight (,),[,],{,} with Type,
• Fix #132

Installation

Any package manager you like

Features

To enable the features you would like to use, just add the according line to your .vimrc.

let g:haskell_enable_quantification = 1    " to enable highlighting of `forall`
let g:haskell_enable_recursivedo = 1       " to enable highlighting of `mdo` and `rec`
let g:haskell_enable_arrowsyntax = 1       " to enable highlighting of `proc`
let g:haskell_enable_pattern_synonyms = 1  " to enable highlighting of `pattern`
let g:haskell_enable_typeroles = 1         " to enable highlighting of type roles
let g:haskell_enable_static_pointers = 1   " to enable highlighting of `static`
let g:haskell_backpack = 1                 " to enable highlighting of backpack keywords
let g:haskell_enable_boolean = 1           " to enable highlighting of `True` and `False`
let g:haskell_enable_ordering = 1          " to enable highlighting of  `LT` and `EQ` and `GT`
let g:haskell_enable_monad_return = 1      " to enable highlighting of `return`
let g:haskell_enable_applicative_pure = 1  " to enable highlighting of `pure`
let g:haskell_enable_delimiter_is_type = 1 " to enable highlighting of `(` and `)` and `[` and `]` and `{` and `}`
