I figured that I should eventually write something talking about my favorite text editor, and how I like it configured. What follows is the explanation of my .vimrc, as well as a description of the plugins that I use. A lot of the credit for this configuration goes to Bart Trojanowski, who has an excellent Vim configuration. At the bottom I’ll have a link to download any of the files themselves if you so desire. I hope you find it useful (everything in fixed-width font is the actual text, everything else is comments about it):

My ~/.vimrc:

Modelines have been abused in the past, and while I haven’t heard of anything lately that would abuse them, it’s always better safe than sorry. This requires the securemodelines vim script

" ---------------------------------------------------------------------------
" first the disabled features due to security concerns
set modelines=0               " no modelines [http://www.guninski.com/vim1.html]
let g:secure_modelines_verbose=0 " securemodelines vimscript
let g:secure_modelines_modelines = 15 " 15 available modelines

Since these are all simple features, I won’t bother to explain them besides the inline comments:

I do like candycode for my terminals (which tend to be black) and I like macvim for my GUI, so I change schemes depending on which I’m using.

if !has("gui_running")
      colorscheme candycode   " yum candy
end
if has("gui_running")
      colorscheme macvim      " macvim == win
      set guioptions-=T       " no toolbar
      set cursorline          " show the cursor line
end

For the taglist plugin, I want it to appear on the right and to quick vim as soon as I close the last file I’m working on.

" Settings for taglist.vim
let Tlist_Use_Right_Window=1
let Tlist_Auto_Open=0
let Tlist_Enable_Fold_Column=0
let Tlist_Compact_Format=0

Misc TOhtml settings

" Settings for :TOhtml
let html_number_lines=1
let html_use_css=1

My status line is basically <filename> [<filetype>] [+] #<buffernum> <linenum>/<totallines>,<columnnum>

" ---------------------------------------------------------------------------
" status line
set laststatus=2
if has('statusline')
        function! SetStatusLineStyle()
                let &stl="%f %y "                       .
                        \"%([%R%M]%)"                   .

                        \""
        endfunc
        call SetStatusLineStyle()

        if has('title')
                set titlestring=%t%(\ [%R%M]%)
        endif

endif

More simple search options, see inline comments

" ---------------------------------------------------------------------------
"  searching
set incsearch                 " incremental search
set ignorecase                " search ignoring case
set hlsearch                  " highlight the search
set showmatch                 " show matching bracket
set diffopt=filler,iwhite       " ignore all whitespace and sync

I *occasionally* use the mouse. If I have to.

" ---------------------------------------------------------------------------
"  mouse stuffs
set mouse=a                   " mouse support in all modes
set mousehide                 " hide the mouse when typing
" this makes the mouse paste a block of text without formatting it
" (good for code)
map <MouseMiddle> <esc>"*p

I prefer not to litter my current directory with backup files, so I put them all in ~/.backup. I also save a lot of line positions in the viminfo file.

" ---------------------------------------------------------------------------
"  backup options
set backup
set backupdir=~/.backup
set viminfo=%100,'100,/100,h,\"500,:100,n~/.viminfo
set history=200
"set viminfo='100,f1

I use ,ss to toggle between spellcheck on and spellcheck off.

" ---------------------------------------------------------------------------
" spelling...
if v:version >= 700

  setlocal spell spelllang=en
  nmap <LocalLeader>ss :set spell!<CR>

endif

Here are all the keyboard shortcuts I use most often:

" ---------------------------------------------------------------------------
" some useful mappings
" Y yanks from cursor to $
map Y y$
" for yankring to work with previous mapping:
function! YRRunAfterMaps()
    nnoremap Y   :<C-U>YRYankCount 'y$'<CR>
endfunction
" toggle list mode
nmap <LocalLeader>tl :set list!<cr>
" toggle paste mode
nmap <LocalLeader>pp :set paste!<cr>
" change directory to that of current file
nmap <LocalLeader>cd :cd%:p:h<cr>
" change local directory to that of current file
nmap <LocalLeader>lcd :lcd%:p:h<cr>
" correct type-o's on exit
nmap q: :q
" save and build
nmap <LocalLeader>wm  :w<cr>:make<cr>
" open all folds
nmap <LocalLeader>fo  :%foldopen!<cr>
" close all folds
nmap <LocalLeader>fc  :%foldclose!<cr>
" ,tt will toggle taglist on and off
nmap <LocalLeader>tt :Tlist<cr>
" ,nn will toggle NERDTree on and off
nmap <LocalLeader>nn :NERDTreeToggle<cr>
" When I'm pretty sure that the first suggestion is correct
map <LocalLeader>r 1z=

I use this one quite often, as I often forget to do “sudo vim file” in the first case, now I don’t have to exit vim to write the file with sudo.

" If I forgot to sudo vim a file, do that with :w!!
cmap w!! %!sudo tee > /dev/null %
" ruby helpers
iab rbang #!/usr/bin/env ruby
iab idef def initialize

I think candycode looks good in all the color modes, but it’s still nice to set it up for different terms.

" ---------------------------------------------------------------------------
" setup for the visual environment
if $TERM =~ '^xterm'
        set t_Co=256
elseif $TERM =~ '^screen-bce'
        set t_Co=256            " just guessing
elseif $TERM =~ '^rxvt'
        set t_Co=88
elseif $TERM =~ '^linux'
        set t_Co=8
else
        set t_Co=16
endif

Switch between tabs with ,tn and ,tp

" ---------------------------------------------------------------------------
" tabs
" (LocalLeader is ",")
map <LocalLeader>tc :tabnew %<cr>    " create a new tab
map <LocalLeader>td :tabclose<cr>    " close a tab
map <LocalLeader>tn :tabnext<cr>     " next tab
map <LocalLeader>tp :tabprev<cr>     " previous tab
map <LocalLeader>tm :tabmove         " move a tab to a new location

Load extensions we need and change some format options for markdown files.

" ---------------------------------------------------------------------------
" auto load extensions for different file types
if has('autocmd')
        filetype plugin indent on
        syntax on

        autocmd BufReadPost *
                \ if line("'\"") > 0|
                \       if line("'\"") <= line("$")|
                \               exe("norm '\"")|
                \       else|
                \               exe "norm $"|
                \       endif|
                \ endif

        " improve legibility
        au BufRead quickfix setlocal nobuflisted wrap number

        " improved formatting for markdown
        " http://plasticboy.com/markdown-vim-mode/
        autocmd BufRead *.mkd  set ai formatoptions=tcroqn2 comments=n:>
        autocmd BufRead ~/.blog/entries/*  set ai formatoptions=tcroqn2 comments=n:>
endif
And that’s the .vimrc
Here are some of the plugins that I used:
  • NERD Commenter – auto comment sections of code
  • NERD Tree – display file tree for directories, like a project view
  • Alternate – Alternate between implementation and header files
  • Compview – Search for a word and display a window with results
  • GetLatestVimScript – Get the latest version of scripts
  • Matchit – Extended % matching
  • Rails – Tons of RoR stuff
  • Securemodelines – Secure modeline support
  • Taglist – display a list of tags from the file
  • VCScommand – help with files under revision control
  • Vimball – install vimball plugins
  • Yankring – have a ring of copy/paste buffers for history pasting
  • C – A collection of helpful things for C (Although mine is heavily customized)
Enough with text, here’s a couple of screenshots of how it looks:


I maintain a pretty-up-to-date copy of most of my configuration files in my github dotfile repository, that’s the best way to get this configuration as well as all the plugins that I use, you can download a tarball of all the files from the github (direct link: here) page as well.

Well, hope someone out there finds these configuration files useful. I welcome any feedback :)

Soon to come: an explanation of the project that I’ve been working on that has taken me away from blogging for so long, an Intrusion Detection System based on Locality events.

Update 10/23/08: After some theme changes, updated screenshot (no NERDtree or taglist shown in the image):

Update 12/9/09: Been over a year, just for a teaser of what it looks like now:
