Ⅲ. 安装方法
使用Vundle管理器安装
在你的.vimrc下添加:Plugin 'begriffs/haskell-vim-now':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 'begriffs/haskell-vim-now':source %
:NeoBundleInstall使用VimPlug管理器安装
在你的.vimrc下添加:Plug 'begriffs/haskell-vim-now':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/begriffs/haskell-vim-nowⅣ. 文档说明
<h2 align="left">Haskell Vim IDE</h2>
In less than ten minutes your Vim will transform into a beautiful
Haskell paradise. (Don't worry, it backs up your original
configuration to ~/.config/haskell-vim-now/backup/.vimrc.yearmonthdate_time.) It also builds all necessary support binaries
including ghcide, hlint, hoogle and more.
No more wading through plugins trying to make them all work together.
In ten minutes you will have a fully functional Vim that looks great
and lets you
- inspect types
- evaluate Haskell
- lint and check
- manipulate tags
- hoogle lookup
- pointfree refactor
- tab complete
- unicode symbols
- highlight DSLs
- work with git
Installation
Just download and run the installer:
curl -L https://git.io/haskell-vim-now > /tmp/haskell-vim-now.sh
bash /tmp/haskell-vim-now.shWARNING: this command, once successful, will make backups and remove your existing VIM configurations (.vim, plugins etc). You can later customize HVN configurations.
Keybindings and commands
The commands are organized into logical groups to help you remember
them.
Types, autocomplete, refactoring, and linting
| <Tab> | Autocomplete with words in file |
| <C-space> | Autocomplete with symbols in your Cabal sandbox |
| ,hr | Apply one refactoring hint at cursor position |
| ,hR | Apply all refactoring suggestions in the file |
| ,hl | Run Haskell linter on file |
| ,hc | Run Haskell compile check on file |
| ,<cr> | Clear type selection |
Hoogle
| ,hh | Run Hoogle on the word under the cursor |
| ,hH | Run Hoogle and prompt for input |
| ,hi | Run Hoogle for detailed information on word under cursor |
| ,hI | Run Hoogle for detailed information and prompt for input |
| ,hz | Close the Hoogle search window |
GHCI repl
If you open a tmux terminal alongside MacVim then you can send Vim
selections to it. This works well for evaluating things in GHCI.
| ,rs | Send selected text to tmux |
| ,rv | Change tmux session, window, and pane attachment |
Git
| ,g? | Last-committed files (Monday morning key) |
| ,gs | Git status (fugitive) |
| ,gg | Git grep |
| ,gl | Git log (extradition) |
| ,gd | Git diff |
| ,gb | Git blame |
Commenting
| gc | Comment / Uncomment selection |
Aligning
| ,a= | Align on equal signs |
| ,a, | Align on commas |
| ,a| | Align on vertical bar |
| ,ap | Align on character of your choice |
Splits and find file
| ,<space> | Fuzzy file find (CtrlP) |
| ,f | Toggle file browser, find file |
| ,F | Toggle file browser |
| ,sj | Open split below |
| ,sk | Open split above |
| ,sh | Open split leftward |
| ,sl | Open split rightward |
Buffers
| ,bp | Previous buffer |
| ,bn | Next buffer |
| ,b<space> | Buffer fuzzy finder |
| ,bd | Delete buffer, keep window open (bbye) |
| ,bo | Close all buffers except the current one |
Misc
| ,ma | Enable mouse mode (default) |
| ,mo | Disable mouse mode |
| ,ig | Toggle indentation guides |
| ,u | Interactive undo tree |
| ,ss | Enable spell checking |
| ,e | Open file prompt with current path |
| ,<cr> | Clear search highlights |
| ,r | Redraw screen |
| C-h | Move cursor to leftward pane |
| C-k | Move cursor to upward pane |
| C-j | Move cursor to downward pane |
| C-l | Move cursor to rightward pane (redraw is ,r instead) |
| gq | Format selection using hindent for haskell buffers (par for others) |
| ,y | Yank to OS clipboard |
| ,d | Delete to OS clipboard |
| ,p | Paste from OS clipboard |
(If you prefer to restore the default screen redraw action of C-l
then add unmap <c-l> to your vimrc.local)
Customizing
After installing this configuration, your .vimrc and .vim will
be under version control. Don't alter these files. Instead, add
your own settings to ~/.config/haskell-vim-now/vimrc.local.pre,~/.config/haskell-vim-now/vimrc.local.
Adding Vim Plugins
Haskell-Vim-Now uses vim-plug
to install plugins. It uses the following vim configuration structure
to determine what to install:
call plug#begin('~/.vim/plugged')
" The plugins are named in github short form, for example:
Plug 'junegunn/vim-easy-align'
" All plug statements must be between plug#begin and plug#end
call plug#end()However the .vimrc file in Haskell-Vim-Now is under version control
so you shouldn't edit it directly. To add a plugin what you should
do is add Plug statements to ~/.config/haskell-vim-now/plugins.vim.
When ready reload .vimrc and run :PlugInstall to install plugins.
Neovim support
The .vimrc configuration is fully compatible with Neovim, and adds a few
Neovim specific mappings for the terminal mode (terminal emulation is activated
with :terminal). The mappings make Esc and c-[hjkl] function as one would
expect them to from normal mode.
The Neovim configuration is found at .config/nvim, and is symlinked just like
regular vim, which means you should only add your own settings to~/.config/haskell-vim-now/vimrc.local.pre, ~/.config/haskell-vim-now/vimrc.local
and ~/.config/haskell-vim-now/plugins.vim.
You can quickly backup and replace your Neovim setup by running the scripts/neovim.sh
script.
Docker image
If you are into developing with Docker, you can use the image.
docker pull haskell:7.8
docker build -t haskell-vim .
docker run --rm -i -t haskell-vim /bin/bash
If instead you want to extract the vim setup from the image that is easy enough
docker build -t haskell-vim .
mkdir ~/.haskell-vim-now
cd ~/.haskell-vim-now
docker run --rm haskell-vim tar -cz -C /root/.haskell-vim-now . > haskell-vim-now.tgz
tar -xzf haskell-vim-now.tgz
However, some things (for example the hoogle database) use absolute paths and don't work correctly.
Advanced install methods
Basic install
In case you want to skip the haskell specific components and want to install
just the common vim config you can use:
bash <(curl -sL https://git.io/haskell-vim-now) --basicInstalling from a fork or clone
If you have a modified fork you can use the --repo option to tell the install
script the location of your repository:
bash <(curl -sL INSTALL-SCRIPT-URL) --repo FORK-URLFor example:
bash <(curl -sL https://raw.githubusercontent.com/begriffs/haskell-vim-now/master/install.sh) --repo https://github.com/begriffs/haskell-vim-now.gitAdditionally the --branch argument can override the default of master used when cloning the repo.
If you have a local git clone you can use install.sh directly
to install from your clone:
install.sh --repo CLONE-PATHInstalling in Nix build environment
Use --nix parameter, in case you want to execute stack installation in nix-shell
bash <(curl -sL https://git.io/haskell-vim-now) --nixTroubleshooting

page for tips on fixing installation problems.
Thank you!
Big thanks to contributors. I'd especially like to thank @SX91 for rewriting the installer and for other major improvements.
