Ⅱ. 基本信息

创建日期：  2014-06-17 使用用户：  18 Github星：  1 插件作者：  Yann Esposito

Ⅲ. 安装方法

使用Vundle管理器安装

在你的.vimrc下添加:

Plugin 'yogsototh/haskell-vim-long-live'

… 然后在Vim中运行以下命令:

:source %
:PluginInstall

对于Vundle版本 < 0.10.2，请用上面的Bundle替换Plugin。

使用NeoBundle管理器安装

在你的.vimrc下添加:

NeoBundle 'yogsototh/haskell-vim-long-live'

… 然后在Vim中运行以下命令:

:source %
:NeoBundleInstall

使用VimPlug管理器安装

在你的.vimrc下添加:

Plug 'yogsototh/haskell-vim-long-live'

… 然后在Vim中运行以下命令:

:source %
:PlugInstall

使用Pathogen管理器安装

在终端中运行以下命令:

cd ~/.vim/bundle
git clone https://github.com/yogsototh/haskell-vim

Ⅳ. 文档说明

This project has two homes.
It is ok to work in github, still, for a better decentralized web
please consider contributing (issues, PR, etc...) throught:

Haskell Syntax/Indentation

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
• More contextual highlighting (e.g. highlight 'as' or 'family' only in approriate places)
• Smarter indentation

Installation

I recommend using [Pathogen][] for installation. Simply clone
this repo into your ~/.vim/bundle directory and you are ready to go.

cd ~/.vim/bundle
git clone https://github.com/raichoo/haskell-vim.git

Manual Installation

Copy content into your ~/.vim directory.

Be sure that the following lines are in your
.vimrc

syntax on
filetype on
filetype plugin indent on

Configuration

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

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.

• let g:haskell_indent_if = 3

  if bool

  then ...
  else ...

• let g:haskell_indent_case = 5

  case xs of

  [] -> ...
  (y:ys) -> ...

• let g:haskell_indent_let = 4

  let x = 0 in

  x

• let g:haskell_indent_where = 6

  where f :: Int -> Int

  f x = x

• let g:haskell_indent_do = 3

  do x <- a

  y <- b

• let g:haskell_indent_in = 1

  let x = 1

  in x
