===============================================================================
===============================================================================
===============================================================================
CONTENTS *haskell-vim-contents*
1. Features |haskell-vim-features|
2. Configuration |haskell-vim-configuration|
3. Highlighting |haskell-vim-indentation|
===============================================================================
FEATURES *haskell-vim-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
* Better Cabal support
===============================================================================
CONFIGURATION *haskell-vim-configuration*
To enable the features you would like to use, just add the according line to
your `.vimrc`.
===============================================================================
HIGHLIGHTING *haskell-vim-highlighting*
`haskell-vim` can highlight additional keywords. This is enabled by setting
the according variable to 1 in the `.vimrc`.
* |haskell-vim-enable-quantification|
* |haskell-vim-enable-recursivedo|
* |haskell-vim-enable-arrowsyntax|
* |haskell-vim-enable-pattern-synonyms|
* |haskell-vim-enable-typeroles|
* |haskell-vim-enable-static-pointers|
* |haskell-vim-classic-highlighting|
* |haskell-vim-disable-TH|
*haskell-vim-enable-quantification*
`g:haskell_enable_quantification` Enables highlighting of `forall`.
*haskell-vim-enable-recursivedo*
`g:haskell_enable_recursivedo` Enables highlighting of `mdo` and `rec`.
*haskell-vim-enable-arrowsyntax*
`g:haskell_enable_arrowsyntax` Enables highlighting of `proc`.
*haskell-vim-enable-pattern-synonyms*
`g:haskell_enable_pattern_synonyms` Enables highlighting of the `pattern` keyword.
*haskell-vim-enable-typeroles*
`g:haskell_enable_typeroles` Enables highlighting of the `role` keyword, as
well as `phantom`, `norminal` and
`representational`.
*haskell-vim-enable-static-pointers*
`g:haskell_enable_static_pointers` Enables highlighting of the `static` keyword.
*haskell-vim-classic-highlighting*
`haskell-vim` has an opinionated highlighting. If you do not like that you can
switch to a more traditional mode by setting `g:haskell_classic_highlighting`
to 1.
*haskell-vim-disable-TH*
Disabling Template Haskell and Quasiquoting syntax is possible by setting
`g:haskell_disable_TH` to `1`.
===============================================================================
INDENTATION *haskell-vim-indentation*
To configure indentation in `haskell-vim` you can use the following variables to
change indentation depth, just add the according line to your `.vimrc`.
You can disable the indentation by setting `g:haskell_indent_disable` to `1`.
