" Vim syntax file " Language: Haskell " Maintainer: Haskell Cafe mailinglist <haskell-cafe@haskell.org> " Last Change: 2004 Feb 23 " 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_more_types - Treat names of other common 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 " " 2004 Feb 19: Added C preprocessor directive handling, corrected eol comments " cleaned away literate haskell support (should be entirely in " lhaskell.vim) " 2004 Feb 20: Cleaned up C preprocessor directive handling, fixed single \ " in eol comment character class " 2004 Feb 23: Made the leading comments somewhat clearer where it comes " to attribution of work.
