Vim

Make Vim a node.js IDE step by step.(将Vim打造为轻便好用的node.js开发环境)。 ###1.Install Vim brew install vim Restart the terminal and when you run vi [profile] or vim it will open the vim you installed. ###2.The Plugin

2.1 Plugin Manager Vundle.vim

The plug-in manager for Vim.

$ git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

Edit the.vimrc,like this(if there is no .vimrc profile in your home path just create it yourself touch .vimrc):

set nocompatible              " be iMproved, required
filetype off                  " required

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
" alternatively, pass a path where Vundle should install plugins
"call vundle#begin('~/some/path/here')

" let Vundle manage Vundle, required
Plugin 'VundleVim/Vundle.vim'
"............................................................
"my Bundle here:
"
">>>>>>>>>>>>>>>>>>>>>>>>
"original repos on github
"
"Bundle 'kien/ctrlp.vim'
">>>>>>>>>>>>>>>>>>>>>>>>
"vimscripts repos
"
"Bundle 'YankRing.vim'
">>>>>>>>>>>>>>>>>>>>>>>>
"non gihut repos
"
"Bundle 'git://git.wincent.com/command-t.git'

"............................................................
" All of your Plugins must be added before the following line
call vundle#end()            " required
filetype plugin indent on    " required
" To ignore plugin indent changes, instead use:
"filetype plugin on
"
" Brief help
" :PluginList       - lists configured plugins
" :PluginInstall    - installs plugins; append `!` to update or just :PluginUpdate
" :PluginSearch foo - searches for foo; append `!` to refresh local cache
" :PluginClean      - confirms removal of unused plugins; append `!` to auto-approve removal
"
" see :h vundle for more details or wiki for FAQ
" Put your non-Plugin stuff after this line

You'd better to have a look at Vim Plugins

---General--- #####2.2.1 vim-node Tools and environment to make Vim superb for developing with Node.js. Like Rails.vim for Node.

---Linter--- #####2.2.2 Tabular Vim script for text filtering and alignment. #####2.2.3 jshint.vim JSHint is a tool that helps to detect errors and potential problems in your JavaScript code. runsudo npm install -g jshint for global installration of jshint install jshint.vim with Vundle install jshint2.vim with Vundle #####2.2.4 jshint2 ---Syntax--- #####2.2.4 syntastic Syntax checking hacks for vim #####2.2.5 vim-javascript Vastly improved Javascript indentation and syntax support in Vim. #####2.2.6 YouCompleteMe A code-completion engine for Vim.

Step：

1.Install YouCompleteMe

2.NOTE: If you want C-family completion, you MUST have the latest Xcode installed along with the latest Command Line Tools (they are installed automatically when you run clang for the first time, or manually by running xcode-select --install)

3.Install CMake withbrew install cmake

4.Compiling YCM with semantic support for C-family languages:

cd ~/.vim/bundle/YouCompleteMe
./install.py --clang-completer

4.Compiling YCM without semantic support for C-family languages:

cd ~/.vim/bundle/YouCompleteMe
./install.py

5.Install tern_for_vim

6.For node.js run:

cd ~/.vim/bundle/YouCompleteMe
./install.py --tern-completer

7.put a .tern-project file in your project directory. It is very finicky, so make sure the syntax is correct. For example, if you try to load a file in tern that is not in the project, autocompletion will not work. More Information

eg.

{
  "libs": [
    "express"
    //"browser",
    //"jquery"
  ],
  "loadEagerly": [
    //"importantfile.js"
  ],
  "plugins": {
    "requirejs": {
      //"baseURL": "./",
      //"paths": {}
    }
  }
}

8.No 8! It's done. It was painful for getting it ready youself ,hah?

There are stil somethings you should pay attention to:

• For me, it displayYouCompleteMe unavailable: requires Vim 7.3.598+ when I usevi [myfile]to edit some file. And this issue can fix it withalias vi='vim'.But it happens when restart the terminal the my way to fix it is add alias vi='vim' to my ~/.bashrc.
• Sometimes you may got the error display just like:can't find module vim/bundle/tern_for_vim/node_modules/tern/bin/tern'.To solve this problem, run:

cd ~/.vim/bundle/tern_for_vim/
npm install tern

#####2.2.7 vim-pug Vim Pug (formerly Jade) template engine syntax highlighting and indention.

issue If you use vundle to manager the plugin, you may meet the trouble that it dosen't work though you have install vim-pug. To fix it you should do these things below in your .vimrc:

1. disable the filetype before vundle with filetype off;
2. enable the filetype below this line call vundle#end() with filetype on You'd better have a look at this issue.

#####2.2.7 flow Adds static typing to JavaScript to improve developer productivity and code quality.

#####2.2.8 vim-indent-guide A Vim plugin for visually displaying indent levels in code.

#####2.2.9 delimitMate Vim plugin, provides insert mode auto-completion for quotes, parens, brackets, etc.

#####2.2.10 rainbow_parentheeses.vim Better Rainbow Parentheses.

---Colorschemes--- #####2.2.10 vim-colors-solarized precision colorscheme for the vim text editor

#####2.2.11 dracula wonderful theme for everything. By the way: 这个系列的主题，真TM不错。每次打开Vim心情瞬间美美哒！O(∩_∩)O哈哈~ 虽然据说是暗黑系风格。 You like it?

#####2.2.12 vim-airline lean & mean status/tabline for vim that's light as air.

---Browsin---

#####2.2.13 NERDTree A tree explorer plugin for vim. #####2.2.14 ctrlp Fuzzy file, buffer, mru, tag, etc finder.

3. Config

The ~/.vimrc profile control almost everything of vim, so you need to pay some of your time to know about it.

You can see my .vimrc as a sample here. For I am a very very newer!

Libraries

• npm: A package manager for javascript.
• pug Pug – robust, elegant, feature rich template engine for Node.js.
• express: Fast, unopinionated, minimalist web framework for node.
• utility: A collection of useful utilities.
• superagent: A small progressive client-side HTTP request library, and Node.js module with the same API, sporting many high-level HTTP client features.
• cheerio:Fast, flexible, and lean implementation of core jQuery designed specifically for the server.
• node-formidable A node.js module for parsing form data, especially file uploads.
• mongoose MongoDB object modeling designed to work in an asynchronous environment.

Errors

1.Error: listen EADDRINUSE：

listen()方法尝试绑定已经被使用的服务器端口。

解决方案：终端输入lsof -i tcp:8888(8888为端口号)获取在该端口运行的进程id（PID）。输出:

COMMAND  PID     USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
node    3742 wuyunhui   12u  IPv6 0xe120a4e962ac90b5      0t0  TCP *:hbci (LISTEN)

然后杀死该进程： kill -9 3742

根据stackoverflow上面的答案最好是在kill -9之前: kill -15，the reason is：

Generally, you should use kill -15 before kill -9 to give the target process a chance to clean up after itself. (Processes can't catch or ignore SIGKILL, but they can and often do catch SIGTERM.) If you don't give the process a chance to finish what it's doing and clean up, it may leave corrupted files (or other state) around that it won't be able to understand once restarted. Nobita的回答

2.Error: Failed to lookup view "error" in views directory

There could be some troubles when using pug with express for jade had been renamed to pug.

You have to change the name past such as error.jade to error.pug, so that the pug can work well.
