1# Janus: Carlhuda's vim Distribution
2
3This is a basic distribution of vim plugins and tools intended to be run
4on top of the latest MacVIM snapshot.
5
6We (Carl and Yehuda) both use this distribution for our own use, and
7welcome patches and contributions to help make it an effective way to
8get started with vim and then use it productively for years to come.
9
10At present, we are still learning to use vim ourselves, so you should
11anticipate a period of rapid development while we get a handle on the
12best tools for the job. So far, we have mostly integrated existing
13plugins and tools, and we anticipate to continue doing so while also
14writing our own plugins as appropriate.
15
16In general, you can expect that the tools we use work well together and
17that we have given careful thought to the experience of using MacVIM
18with the tools in question. If you run into an issue using it, please
19report an issue to the issue tracker.
20
21## Pre-requisites
22
23Janus is built primarily for [MacVim](http://code.google.com/p/macvim/) on OSX.
24Download it [here](https://github.com/b4winckler/macvim/downloads).
25
26Alternatively, you can use Janus with the bundled console `vim` installation on
27OSX (via Terminal), or with any other `vim` or `gvim` installation.
28
29Linux users can install `gvim` for an experience identical to MacVim.
30On Debian/Ubuntu, simply `apt-get install vim-gnome`. For remote
31servers, install console vim with `apt-get install vim-nox`.
32
33On a fresh Ubuntu install you also have to install the packages `rake` and `ruby-dev`
34before running the install script and `exuberant-ctags` for ctags
35support.
36
37## Installation
38
390. `for i in ~/.vim ~/.vimrc ~/.gvimrc; do [ -e $i ] && mv $i $i.old;
40 done`
411. `git clone git://github.com/carlhuda/janus.git ~/.vim`
422. `cd ~/.vim`
433. `rake`
44
45or
46
47 `curl https://raw.github.com/carlhuda/janus/master/bootstrap.sh -o - | sh`
48
49## Customization
50
51Create `~/.vimrc.local` and `~/.gvimrc.local` for any local
52customizations.
53
54For example, to override the default color schemes:
55
56 echo color desert > ~/.vimrc.local
57 echo color molokai > ~/.gvimrc.local
58
59If you want to add additional Vim plugins you can do so by adding a
60`~/.janus.rake` like so:
61
62 vim_plugin_task "zencoding", "git://github.com/mattn/zencoding-vim.git"
63 vim_plugin_task "minibufexpl", "git://github.com/fholgado/minibufexpl.vim.git"
64
65If you do not wish to use one of the plugins Janus provides out of the
66box you can have it skipped using the `skip_vim_plugin` method in
67`~/.janus.rake`:
68
69 skip_vim_plugin "color-sampler"
70
71**Note**: Skipping the plugin will only apply to installation. It won't
72remove configurations or mappings Janus might have added for it.
73
74## Updating to the latest version
75
76To update to the latest version of the distribution, just run `rake`
77again inside your `~/.vim` directory.
78
79# Intro to VIM
80
81Here's some tips if you've never used VIM before:
82
83## Tutorials
84
85* Type `vimtutor` into a shell to go through a brief interactive
86 tutorial inside VIM.
87* Read the slides at [VIM: Walking Without Crutches](http://walking-without-crutches.heroku.com/#1).
88* Watch the screencasts at [vimcasts.org](http://vimcasts.org/)
89* Watch Derek Wyatt's energetic tutorial videos at [his site](http://www.derekwyatt.org/vim/vim-tutorial-videos/)
90* Read wycats' perspective on learning vim at
91 [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/)
92* Read this and other answers to a question about vim at StackOverflow:
93 [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)
94
95## Modes
96
97* VIM has two modes:
98 * insert mode- stuff you type is added to the buffer
99 * normal mode- keys you hit are interpretted as commands
100* To enter insert mode, hit `i`
101* To exit insert mode, hit `<ESC>`
102
103## Useful commands
104
105* Use `:q` to exit vim
106* Certain commands are prefixed with a `<Leader>` key, which maps to `\`
107 by default. Use `let mapleader = ","` to change this.
108* Keyboard [cheat sheet](http://walking-without-crutches.heroku.com/image/images/vi-vim-cheat-sheet.png).
109
110# Features
111
112This vim distribution includes a number of packages built by others.
113
114## Base Customizations
115
116Janus ships with a number of basic customizations for vim:
117
118* Line numbers
119* Ruler (line and column numbers)
120* No wrap (turn off per-buffer via set :wrap)
121* Soft 2-space tabs, and default hard tabs to 2 spaces
122* Show tailing whitespace as `.`
123* Make searching highlighted, incremental, and case insensitive unless a
124 capital letter is used
125* Always show a status line
126* Allow backspacing over everything (identations, eol, and start
127 characters) in insert mode
128* `<Leader>e` expands to `:e {directory of current file}/` (open in the
129 current buffer)
130* `<Leader>tr` expands to `:te {directory of current file}/` (open in a
131 new MacVIM tab)
132* `<C-P>` inserts the directory of the current file into a command
133
134## "Project Drawer" aka [NERDTree](http://github.com/wycats/nerdtree)
135
136NERDTree is a file explorer plugin that provides "project drawer"
137functionality to your vim projects. You can learn more about it with
138:help NERDTree.
139
140**Customizations**: Janus adds a number of customizations to the core
141NERDTree:
142
143* Use `<Leader>n` to toggle NERDTree
144* Ignore `*.rbc` and `*~` files
145* Automatically activate NERDTree when MacVIM opens and make the
146 original buffer the active one
147* Provide alternative :e, :cd, :rm and :touch abbreviations which also
148 refresh NERDTree when done (when NERDTree is open)
149* When opening vim with vim /path, open the left NERDTree to that
150 directory, set the vim pwd, and clear the right buffer
151* Disallow `:e`ing files into the NERDTree buffer
152* In general, assume that there is a single NERDTree buffer on the left
153 and one or more editing buffers on the right
154
155## [Ack.vim](http://github.com/mileszs/ack.vim)
156
157
158Ack.vim uses ack to search inside the current directory for a pattern.
159You can learn more about it with :help Ack
160
161**Customizations**: Janus rebinds command-shift-f (`<D-F>`) to bring up
162`:Ack `.
163
164## [Align](http://github.com/tsaleh/vim-align)
165
166Align lets you align statements on their equal signs, make comment
167boxes, align comments, align declarations, etc.
168
169* `:5,10Align =>` to align lines 5-10 on `=>`'s
170
171## [Command-T](https://wincent.com/products/command-t)
172
173Command-T provides a mechanism for searching for a file inside the
174current working directory. It behaves similarly to command-t in
175Textmate.
176
177**Customizations**: Janus rebinds command-t (`<D-t>`) to bring up this
178plugin. It defaults to `<Leader>t`.
179
180## [ConqueTerm](http://code.google.com/p/conque/)
181
182ConqueTerm embeds a basic terminal inside a vim buffer. The terminal has
183an insert mode in which you can type commands, tab complete and use the
184terminal like normal. You can also escape out of insert mode to use
185other vim commands on the buffer, like yank and paste.
186
187**Customizations**: Janus binds command-e (`<D-e>`) to bring up
188`:ConqueTerm bash --login` in the current buffer.
189
190**Note**: To get colors working, you might have to `export TERM=xterm`
191and use `ls -G` or `gls --color`
192
193## [indent\_object](http://github.com/michaeljsmith/vim-indent-object)
194
195Indent object creates a "text object" that is relative to the current
196ident. Text objects work inside of visual mode, and with `c` (change),
197`d` (delete) and `y` (yank). For instance, try going into a method in
198normal mode, and type `v ii`. Then repeat `ii`.
199
200**Note**: indent\_object seems a bit busted. It would also be nice if
201there was a text object for Ruby `class` and `def` blocks.
202
203## [surround](http://github.com/tpope/vim-surround)
204
205Surround allows you to modify "surroundings" around the current text.
206For instance, if the cursor was inside `"foo bar"`, you could type
207`cs"'` to convert the text to `'foo bar'`.
208
209There's a lot more; check it out at `:help surround`
210
211## [NERDCommenter](http://github.com/ddollar/nerdcommenter)
212
213NERDCommenter allows you to wrangle your code comments, regardless of
214filetype. View `:help NERDCommenter` for all the details.
215
216**Customizations**: Janus binds command-/ (`<D-/>`) to toggle comments.
217
218## [SuperTab](http://github.com/ervandew/supertab)
219
220In insert mode, start typing something and hit `<TAB>` to tab-complete
221based on the current context.
222
223## ctags
224
225Janus includes the [TagList](http://github.com/vim-scripts/taglist.vim)
226plugin, which binds `:Tlist` to an overview panel that lists all ctags
227for easy navigation.
228
229**Customizations**: Janus binds `<Leader>rt` to the ctags command to
230update tags.
231
232**Note**: For full language support, run `brew install ctags` to install
233exuberant-ctags.
234
235**Tip**: Check out `:help ctags` for information about VIM's built-in
236ctag support. Tag navigation creates a stack which can traversed via
237`Ctrl-]` (to find the source of a token) and `Ctrl-T` (to jump back up
238one level).
239
240## Git Support ([Fugitive](http://github.com/tpope/vim-fugitive))
241
242Fugitive adds pervasive git support to git directories in vim. For more
243information, use `:help fugitive`
244
245Use `:Gstatus` to view `git status` and type `-` on any file to stage or
246unstage it. Type `p` on a file to enter `git add -p` and stage specific
247hunks in the file.
248
249Use `:Gdiff` on an open file to see what changes have been made to that
250file
251
252## [Gist-vim](http://github.com/mattn/gist-vim)
253
254Nice [gist integration](https://github.com/mattn/gist-vim) by mattn.
255Requires exporting your `GITHUB_TOKEN` and `GITHUB_USER` as environment
256variables or setup your [GitHub token config](http://help.github.com/git-email-settings/).
257
258Try `:Gist`, `:Gist -p` and visual blocks.
259
260## [ZoomWin](http://github.com/vim-scripts/ZoomWin)
261
262When working with split windows, ZoomWin lets you zoom into a window and
263out again using `Ctrl-W o`
264
265**Customizations**: Janus binds `<Leader><Leader>` to `:ZoomWin`
266
267## Additional Syntaxes
268
269Janus ships with a few additional syntaxes:
270
271* Markdown (bound to \*.markdown, \*.md, and \*.mk)
272* Mustache (bound to \*.mustache)
273* Arduino (bound to \*.pde)
274* Haml (bound to \*.haml)
275* Sass (bound to \*.sass)

278* Map Gemfile, Rakefile, Vagrantfile and Thorfile to Ruby
279* Git commits (set your `EDITOR` to `mvim -f`)
280
281## Color schemes
282
283Janus includes the vim color sampler pack, which includes [over 100
284popular color themes](http://www.vi-improved.org/color_sampler_pack/):
