Dotvim

An attempt at The Ultimate Vim Configuration™ ;)

All the right plugins are in. Nerdtree, CtrlP, you name it.

The focus is on supporting Rails, but there is a lot of generic stuff too, so it will surely serve you well with any language of your choice.

The config is using Vundle for easy upgrading.

Some help tips are provided for some of the plugins. please check out the plugin's docs for more info.

Follow @vkushner and @astrails on Twitter to receive announcements of new versions, tips, etc.

#### Contents ##### Installation

From your homedirectory (on Linux/Mac OSX):

  • git clone git://github.com/astrails/dotvim.git

  • ln -sfn dotvim .vim

  • ln -sfn dotvim/vimrc .vimrc

  • cd .vim; make install

    Note: if you already have ~/.vim ~/.vimrc REMOVE THEM (you might want to backup them first :)

  • create ~/.vimrc.before or ~/.vimrc.after if you want to have some local/personal settings you don't want to commit into the repo. see "Local Configuration"

    IMPORTANT: always add a colorscheme to your ~/.vimrc.after file. Even if you use the defaults scheme add colorscheme default. Othewise you will get a highlighting error "E411: highlight group not found: Normal" during vim startup.

IMPORTANT: vim-powerline requires some extra glyphs to work properly. Check the official documentation on font installation and follow the instructions. If you do not, then strange symbols will be displayed instead. While this is not critical, it remains pretty annoying.

#### General configuration

, is used as mapleader backslash is used as localleader

  • ,e mapped to :e **/. essentially you do ,efoo<tab> to get a list of all files starting with foo
  • ,s - toggle invisible characters display
  • ,n - next quicklist result (like :Ggrep etc)
  • ,N - previous quicklist result (like :Ggrep etc)
  • Ctrl-E - switch between 2 last buffers (its just a :b#<cr> :)
  • Ctrl-N to cancel current search highlighing
  • ,f global Ggrep for word under the cursor or for selection
  • +, - - easily inc/decrement integers
  • ,W - remove trailing spaces
  • Ctrl-h/j/k/l - simplified split panes navigation
  • ,d - :diffupdate
  • ,dp - :diffput
  • ,dg - :diffget
  • %% - in control mode, i.e. after you typed : it will expand to the directory name of the currently opened file.

Check out the 'plugins.vim' and 'after/plugin/bindings.vim' files for more...

top

#### Local configuration

For easy upgrades its preferable not to change the dotvim configuration files. Instead you can add your own local configuration into one of the local override files. There are several override files supported by dotvim.

They are loaded in the following order:

  • base dotvim configuration (global, plugin configurations, bindings, macros)

  • ~/.local-before.vim [deprecated]

  • ~/.vimrc.before

    Loaded before the plugins

    This is where you should pre-set various plugin flags, enable/disable options etc. This is for things you would normally put into your vimrc file.

  • ~/.gvimrc.before [when GUI running]

  • vim plugins

  • dotvim bindings and overrides (loaded from ~/.vim/after.vim)

  • .local-after.vim [deprecated]

  • .vimrc.after

    Loaded after the plugins

    This is where you can override settings set by plugins that have no customization options.

  • .gvimrc.after [when GUI running]

top

#### Backups

Backups and swapfiles are disabled. I really hate them both.

You can re-enable backups by adding the following to your ~/.local.vim:

set backup

and swapfiles by

set swapfile

backup dir is set to ~/.backup/

The directory is created if it doesn't exist.

top

#### Persistent Undo

Persistent undos are enabled by default.

You can disable by adding the following to your ~/.local.vim:

set noundo

top

#### Macros

I included a couple of macros that I frequently use in macros.vim which is loaded from after.vim:

  • @q (re)format paragraph forward
  • @s enclose selection with double *. e.g. **foo**.

You really should start writing your own macros. The life will never be the same ;).

I recommend editing your macros in a vim buffer.

To load a macro into a register you can 'yank' it.

For example if you have a line with a macro and cursor is at the beginning of it "ay$ will load the macro into register a, so that you will be able to execute it with @a.

    Note: the old Lokaltog/vim-powerline project is now deprecated in favor of Lokaltog/powerline which is python based and is supposed to be better.

    Unfortunately I coudn't get it to work on my OSX machine. Even more unfortunately the old project has changed default branch to new-plugin which is empty except for the README file announcing the new project location. This makes it impossible to use with vundle. The solution for now is that I forked the original plugin project and make it available under astrails account in a form suitable for vundle.

  • ]p paste with autoindent.
  • ga print ascii value of character under the cursor
  • g# like "#", but without using "<" and ">"
  • g< display previous command output

  • zb scroll cursor line to bottom
  • CTRL-W x exchange current window with n-th window (or next if no count given)
  • gv reselect last selection
  • gt next tab
  • gT prev tab
  • ci change inside delimiters
  • di delete inside delimiters
  • @@ execute last macro
  • "xyy copy line into x register (replace x with any other)
  • <C-R>x while in insert mote will paste content of register x (replace x with any other)
  • "xp paste from register x
  • :reg Display the contents of all numbered and named registers.

#### Russian Translit Layout support

There is ~/.vim/bindings-ru-translit.vim file.

OSX has a nice russian translit keyboard layout which I use when I need to write any russian text. The problem is that once I go to the normal mode nothing works. This is an attempt to make vim at least partially useful when the kerboard is in russioan translit mode and not in the default US mode. The idea is to remap the russian characters to the english characters that correspond to the same keyboard key. And a couple of userful multy-key combinations.

Similar can be done for other keyboard layouts, your pull requests are welcome ;).

To use this feature: just include the file from your ~/.local.vim:

source ~/.vim/bindings-ru-translit.vim

top

#### writer.vim

My attempt to make vim look like iWriter ;) You can read about the details on our blog.

In short, just do :so ~/.vim/writer.vim when you are going to do some plain text writing.
