# Janus: Vim Distribution

This is a distribution of plug-ins and mappings for Vim, Gvim and

MacVim.

It is designed to provide minimal working environment using the most

popular plug-ins and the most common mappings.

The distribution is completely customisable using a `~/.vimrc.before`

and `~/.vimrc.after` Vim RC files.

## Updating to the latest version

To update to the latest version of the distribution, just run `rake`

inside your `~/.vim` directory.

NOTE: If you ever have an error updating Janus relating to a

missing commit in a submodule, please try running `rake` again before

submitting an issue.

## Mailing list

The mailing list is hosted at [Google

Groups](http://groups.google.com/group/janus-vimius), please join it for

discussion and announcements.

## Pre-requisites

The distribution is designed to work with Vim >= 7.3.

The distribution also requires `ack`, `ctags`, `git`, `ruby` and `rake`.

For the most comfortable experience, use the GUI version of Vim. Linux

users should install `gvim`, OSX users should install

[MacVim](http://code.google.com/p/macvim/). The recommended way of

installing MacVim is using

[Homebrew](http://mxcl.github.com/homebrew/), but before installing

MacVim you need to use system-wide Python (If you are using python that

is):

* If you're using **pythonbrew**: do `pythonbrew off`

```bash

$ brew install macvim

```

If you don't use Homebrew, you can still download MacVim

[here](https://github.com/b4winckler/macvim/releases).

Take a look at the [Pre-requisites wiki

page](https://github.com/carlhuda/janus/wiki/Pre-requisites) for more

information.

## Installation

To install Janus, please use our [automatic

installer](https://github.com/carlhuda/janus/blob/master/bootstrap.sh)

, which backs up any Vim files found in your home folder and installs

Janus.

```bash

$ curl -L https://bit.ly/janus-bootstrap | bash

```

## Customization

You can use `~/.gvimrc.before` and `~/.vimrc.before` for settings Janus itself uses,

such as the __leader__ setting. You may also use `~/.gvimrc.after` and

`~/.vimrc.after` for any additional settings; it is also a good place for

overriding Janus settings, as both files will be loaded at the end of

Janus.

For example, to override the default color schemes:

```bash

$ echo 'color desert'  >> ~/.vimrc.after

$ echo 'color molokai' >> ~/.gvimrc.after

```

If you want to do additional customization or add more Vim plugins,

create a `~/.janus` directory and add your plugins there, either with a

`git clone` or by adding submodules to your own git repository there.

This directory is treated like a normal pathogen directory. For example:

```bash

$ cd ~/.janus

$ git clone https://github.com/vim-scripts/Rename2.git rename2

```

Or, if you have a git repository in `~/.janus`, you can use a submodule:

```bash

$ cd ~/.janus

$ git submodule add https://github.com/vim-scripts/Rename2.git rename2

```

If you would like to disable an included plug-in, you can do that with

the `janus#disable_plugin()` function from inside your

`~/.vimrc.before`. This function takes a plug-in name as an argument

without the group. For example, if you would like to disable the

NERDCommenter plug-in, you can do that with the command:

```bash

$ echo "call janus#disable_plugin('nerdcommenter')" >> ~/.vimrc.before

```

**WARNING**: We've noticed over and over, that people fork Janus just to

customize it. This is bad practice for several reasons and you should

not do that, and here's why:

- Janus is fully customisable and there's no need to change the core for

  using a different plugin fork or using a different mapping.

- Forking means maintenance; maintenance means burden. Do not burden

  yourself with maintaining a fork; that's what the `~/.janus` folder

  is for.

If you find yourself needing a customisation that is not possible with

the current setup, then please open an issue or consider submitting a

pull request to make it possible to continue using/improving the official repo.

**WARNING**: Any **uncommited** files inside the **janus** folder will be

removed the next time you run `rake` so make sure to either put them in

the custom folder (`~/.janus`), or commit them. We clean the janus

folder in case we replace a manually installed plugin (using rake tasks)

with a submodule.

For more information on how to customize Janus, you might want to take

a look at the [Customization wiki

page](https://github.com/carlhuda/janus/wiki/Customization).

Additional you can see [Example](https://github.com/khusnetdinov/.janus) of customization.

# Intro to VIM

Here're some tips in case you've never used VIM before:

## Tutorials

* Type `vimtutor` into a shell to go through a brief interactive

  tutorial inside VIM.

* Watch this presentation at [VIM: Walking Without Crutches](https://vimeo.com/16458939) or read the [slides on Speaker Deck](https://speakerdeck.com/nelstrom/vim-precision-editing-at-the-speed-of-thought).

* Watch the screencasts at [vimcasts.org](http://vimcasts.org/)

* Watch Derek Wyatt's energetic tutorial videos at [his site](http://derekwyatt.org/vim/tutorials/)

* Read wycats' perspective on learning Vim at

  [Everyone who tried to convince me to use vim was wrong](http://yehudakatz.com/2010/07/29/everyone-who-tried-to-convince-me-to-use-vim-was-wrong/)

* Read this and other answers to a question about vim at StackOverflow:

  [Your problem with Vim is that you don't grok vi](http://stackoverflow.com/questions/1218390/what-is-your-most-productive-shortcut-with-vim/1220118#1220118)

* Read the [Getting Started with Vim](http://www.sitepoint.com/getting-started-vim/) tutorial on SitePoint

* Read the [Effective Rails Development with Vim](http://www.sitepoint.com/effective-rails-development-vim/) tutorial on SitePoint

## Modes

* VIM has three modes:

  * insert mode- stuff you type is added to the buffer

  * normal mode- keys you hit are interpreted as commands

  * visual mode- allows you to select blocks of text

* To enter insert mode, hit `i`

* To exit insert mode, hit ``

* To enter visual mode, hit `v`

* To exit visual mode, hit ``

## Useful commands

* Use `:q` to exit vim

* Certain commands are prefixed with a `` key, which maps to `\`

  by default. You can, for example, use `let mapleader = ","` to change this to a comma. If you want this

  to be in effect for uses of `` in the .vimrc file, make sure to define

  this in `~/.vimrc.before`

* Keyboard [cheat sheet](http://vim.rtorr.com/).

# Features

This Vim distribution includes a number of packages built by others.

## Base Customizations

Janus ships with a number of basic customizations for vim:

* Line numbers

* Ruler (line and column numbers)

* No wrap (turn off per-buffer via :set wrap)

* Soft 2-space tabs, and default hard tabs to 2 spaces

* Show trailing whitespace as `.`

* Make searching highlighted, incremental, and case insensitive unless a

  capital letter is used

* Always show a status line

* Allow backspacing over everything (indentations, eol, and start

  characters) in insert mode

* `` inserts the directory of the current file into a command

* Automatically resize splits when resizing the Vim window (GUI only)

* `ew` expands to `:e (directory of current file)/` (open in the

  current buffer)

* `es` expands to `:sp (directory of current file)/` (open in a

  horizontal split)

* `ev` expands to `:vsp (directory of current file)/` (open in

  a vertical split)

* `et` expands to `:tabe (directory of current file)/` (open in

  a new tab)

* Write a privileged file with `:SudoW` or `:SudoWrite`, it will prompt

  for sudo password when writing

* `` toggles paste mode

* `fef` formats the entire file

* `u` converts the entire word to uppercase

* `l` converts the entire word to lowercase

* `U` converts the first char of a word to uppercase

* `L` converts the first char of a word to lowercase

* `cd` changes the path to the active buffer's file

* `md` creates the directory of the active buffer's file

  (For example, when editing a new file for which the path does not

exist.)

* `gw` swaps the current word with the following word

* `ul` underlines the current line with `=`

* `tw` toggles wrap

* `fc` finds the next conflict marker (tested with Git

  conflicted files)

* Remap `` and `` to `gj` and `gk` (Wrapped text is not

  considered a single long line of text.)

* `hs` toggles highlight search

* `=` adjusts viewports to the same size (`=`)

* `!` invokes kwbd plugin; it closes all open buffers in the open

  windows but keeps the windows open

## [Ack.vim](http://github.com/mileszs/ack.vim)

Ack.vim uses ack to search inside the current directory for a pattern.

You can learn more about it with :help Ack.

**Customizations**: Janus rebinds command-shift-f (``) to bring up

`:Ack `.

## [CtrlP](https://github.com/ctrlpvim/ctrlp.vim)

Fuzzy file, buffer, mru and tag finder. Replaces [Command-T](https://github.com/wincent/Command-T)

**Customizations**: For users of Command-T Janus maps CtrlP to command-t (``)

## [NERDCommenter](http://github.com/ddollar/nerdcommenter)

NERDCommenter allows you to wrangle your code comments, regardless of

filetype. View `:help NERDCommenter` for all the details.

**Customizations**: Janus binds command-/ (``) to toggle comments.

## [NERDTree](https://github.com/scrooloose/nerdtree)

NERDTree is a file explorer plugin that provides "project drawer"

functionality to your vim projects.  You can learn more about it with

:help NERDTree.

**Customizations**: Janus adds a number of customizations to the core

NERDTree:

* Use `n` to toggle NERDTree

* Ignore compiled ruby, python, and java files

* When opening vim with vim /path, open the left NERDTree to that

  directory, set the vim pwd, and clear the right buffer

* In general, assume that there is a single NERDTree buffer on the left

  and one or more editing buffers on the right

## [Unimpaired](https://github.com/tpope/vim-unimpaired)

This plugin provides a lot of useful mappings, here's a brief example of

what it does provide:

* `[b` to go to the previous buffer

* `]b` to go to the next buffer

* `[n` to go to the previous SCM conflict marker

* `]n` to go to the next SCM conflict marker

Please check [`:help

unimpaired`](https://github.com/tpope/vim-unimpaired/blob/master/doc/unimpaired.txt)

for a complete list

## [SuperTab](http://github.com/ervandew/supertab)

In insert mode, start typing something and hit `` to tab-complete

based on the current context.

## [Syntastic](https://github.com/scrooloose/syntastic/)

Syntastic is a syntax checking plugin that runs files through external syntax

checkers as they are saved and opened. If syntax errors are detected, the user

is notified and is happy because they didn't have to compile their code or

execute their script to find them.

Please see [`:help

syntastic`](https://github.com/vim-syntastic/syntastic/blob/master/doc/syntastic.txt)

for more information.

## [Tagbar](https://github.com/majutsushi/tagbar)

Tagbar is a vim plugin for browsing the tags of source code files.

**Customizations**: Janus binds `rt` to toggle Tagbar.

## [SnipMate](https://github.com/garbas/vim-snipmate)

SnipMate defines text snippets (a series of characters) that expand to

a useful piece of code when tab is pressed.  For example, in a Ruby

file, def`` expands to:

```ruby

def method_name

end

```

After typing in the method name, press tab again to put the cursor right

where you want it on the next line.  [This repository](https://github.com/honza/vim-snippets/tree/master/snippets)

has a full list of the Snippets that are available in Janus.

## [EasyMotion](https://github.com/Lokaltog/vim-easymotion)

EasyMotion provides a much simpler way to use some motions in vim. It

takes the `` out of `w` or `f{char}` by highlighting

all possible choices and allowing you to press one key to jump directly

to the target.

When one of the available motions is triggered, all visible text

preceding or following the cursor is faded, and motion targets are

highlighted.

EasyMotion is triggered by one of the provided mappings.

check EasyMotion's [home

page](https://github.com/Lokaltog/vim-easymotion) for more information.

## [NrrwRgn](https://github.com/chrisbra/NrrwRgn)

Narrowing means focussing on a region and making the rest inaccessible.

You simply select the region, call :NarrowRegion and the selected part

will open in a new scratch buffer. The rest of the file will be

protected, so you won't accidentally modify that buffer. In the new

buffer, you can do a global replace, search or anything else to modify

that part. When you are finished, simply write that buffer (e.g. by

|:w|) and your modifications will be put in the original buffer making

it accessible again.

## Git Support ([Fugitive](http://github.com/tpope/vim-fugitive))

Fugitive adds pervasive git support to git directories in vim. For more

information, use `:help fugitive`

Use `:Gstatus` to view `git status` and type `-` on any file to stage or

unstage it. Type `p` on a file to enter `git add -p` and stage specific

hunks in the file.

Use `:Gdiff` on an open file to see what changes have been made to that

file

**customizations**:

* `gb` maps to `:Gblame`

* `gs` maps to `:Gstatus`

* `gd` maps to `:Gdiff`

* `gl` maps to `:Glog`

* `gc` maps to `:Gcommit`

* `gp` maps to `:Git push`

## [Git Gutter](http://github.com/airblade/vim-gitgutter)

A Vim plugin which shows a git diff in the 'gutter' (sign column). It

shows whether each line has been added, modified, and where lines have

been removed. You can also stage and revert individual hunks.

## [ZoomWin](http://github.com/vim-scripts/ZoomWin)

When working with split windows, ZoomWin lets you zoom into a window and

out again using `Ctrl-W o`

**Customizations**: Janus binds `zw` to `:ZoomWin`

## [JSON](https://github.com/elzr/vim-json)

Better JSON and JSONP with distinct highlighting for keywords versus

values, strings colored differently from numbers and booleans and double

quotes concealed (disable with `let g:vim_json_syntax_conceal = 0` in

`~/.vimrc.after`, folding of {...} and [...] blocks (enable with

`:setlocal foldmethod=syntax`, and JSON-specific warnings highlighted in

red.

## [BufferGator](https://github.com/jeetsukumaran/vim-buffergator)

Buffergator is a plugin for listing, navigating between, and selecting

buffers to edit. Upon invocation (using the command, `:BuffergatorOpen`

or `BuffergatorToggle`, or the provided key mapping, `b`), a

`catalog` of listed buffers are displayed in a separate new window split

(vertical or horizontal, based on user options; default = vertical).

From this "buffer catalog", a buffer can be selected and opened in an

existing window, a new window split (vertical or horizontal), or a new

tab page.

Selected buffers can be "previewed", i.e. opened in a window or tab

page, but with focus remaining in the buffer catalog. Even better, you

can "walk" up and down the list of buffers shown in the catalog by using

`` (or ``) / `` (or ``). These keys select the

next/previous buffer in succession, respectively, opening it for preview

without leaving the buffer catalog viewer.

## [Vroom](https://github.com/skalnik/vim-vroom)

VRoom is a plugin inspired by [Gary Bernhardt's vim

config](https://github.com/garybernhardt/dotfiles/blob/69330074b7a15c67efa4594a71fa91592f1ce4f9/.vimrc#L286-342)

for running your ruby tests/specs/features.

Imagine you're hacking on a Rails controller, when you switch to the

test or specs for the controller, you can use `r` to run all the

specs or `R` to run the closest spec, then you can jump back to

the controller hack on it and use `r` to run the last spec you

ran last time, so you don't need to open the test again.

Then benefits of this plugin are to centralize your workflow in one

window, one software to do it all, which is a huge speedup over using

`tmux` or multiple terminal tabs.

## [vim-multiple-cursors](https://github.com/terryma/vim-multiple-cursors)

Out of the box, all you need to know is a single key `Ctrl-n`. Pressing the key

in Normal mode highlights the current word under the cursor in Visual mode and

places a virtual cursor at the end of it. Pressing it again finds the next

occurrence and places another virtual cursor at the end of the visual selection.

If you select multiple lines in Visual mode, pressing the key puts a virtual

cursor at every line and leaves you in Normal mode.

More at [QuickStart](https://github.com/terryma/vim-multiple-cursors/blob/master/README.md#quick-start)

## [vim-trailing-whitespace](https://github.com/bronson/vim-trailing-whitespace)

This plugin causes all trailing whitespace to be highlighted in red.

To fix the whitespace errors, just call :FixWhitespace.  By default it

operates on the entire file.  Pass a range (or use V to select some lines)

to restrict the portion of the file that gets fixed.

## Additional Syntaxes

Janus ships with a few additional syntaxes:

* Markdown (bound to \*.markdown, \*.md, and \*.mk)

* Markdown auto styling (disabled by setting

  `g:disable_markdown_autostyle` in `~/.vimrc.before` => `let

  g:disable_markdown_autostyle = 1`)

* Mustache (bound to \*.mustache)

* Haml (bound to \*.haml)

* Sass (bound to \*.sass)

* SCSS (bound to \*.scss)

* An improved JavaScript syntax (bound to \*.js)

* Javascript for any file having `nodejs` in the shebang.

* Map Gemfile, Rakefile, Vagrantfile, Procfile, Thorfile, config.ru and

  *.rake to Ruby.

* Git commits (set your `EDITOR` to `vim -f` or  `mvim -f` on OSX)

  `$ echo "export EDITOR='vim -f'" >> ~/.bashrc`, you can also use Git

  global config to set this if you have EDITOR set to something else

  `$ git config --global core.editor 'vim -f'`
