" Vim syntax file
"
" Modification of vims Haskell syntax file:
" - match types using regular expression
" - highlight toplevel functions
" - use "syntax keyword" instead of "syntax match" where appropriate
" - functions and types in import and module declarations are matched
" - removed hs_highlight_more_types (just not needed anymore)
" - enable spell checking in comments and strings only
" - FFI highlighting
" - QuasiQuotation
" - top level Template Haskell slices
" - PackageImport
"
" TODO: find out which vim versions are still supported
"
" From Original file:
" ===================
"
" Language: Haskell
" Maintainer: Haskell Cafe mailinglist <haskell-cafe@haskell.org>
" Last Change: 2010 Feb 21
" Original Author: John Williams <jrw@pobox.com>
"
" Thanks to Ryan Crumley for suggestions and John Meacham for
" pointing out bugs. Also thanks to Ian Lynagh and Donald Bruce Stewart
" for providing the inspiration for the inclusion of the handling
" of C preprocessor directives, and for pointing out a bug in the
" end-of-line comment handling.
"
" Options-assign a value to these variables to turn the option on:
"
" hs_highlight_delimiters - Highlight delimiter characters--users
" with a light-colored background will
" probably want to turn this on.
" hs_highlight_boolean - Treat True and False as keywords.
" hs_highlight_types - Treat names of primitive types as keywords.
" hs_highlight_debug - Highlight names of debugging functions.
" hs_allow_hash_operator - Don't highlight seemingly incorrect C
" preprocessor directives but assume them to be
" operators
"
