It’s time to blog about my .vimrc — maybe someone finds some useful lines in it. It has grown over the years, aggregated from various sources all over the nets, and also includes some stuff I figured out myself.
The first few lines adjust some default settings like line numbering, etc.
set number
set lbr
set fdc=0
set vb
set expandtab
set shiftwidth=2
set tabstop=2
set linespace=0
set autoindent
set smartindent
set mouse=a
set cursorline
syntax on
set showcmd
set autowrite
set noautochdir
The more interesting options are autowrite and autochdir. autowrite automatically saves everyting when you do a :make, and autochdir automatically sets the working directory to the directory where the file in the current buffer is. I disabled this though, because I got used to manually changing directories again.
Yes, I use space indentation where I have the choice.
Next are some key mappings:
nmap <silent> <c-n> :NERDTreeToggle<CR>
set hlsearch
map <silent> <c-k> :nohlsearch<CR>
map j gj
map k gk
The first mapping is for the NERDTree-Plugin, a little file browser for vim.
The hlsearch option activates the highlighting of all hits when you search for something with / or do a search and replace. When I press Ctrl-K, the highlighting is disabled. It automatically re-activates the next time I search for something though.
I mapped j and k to gj and gk respectively, so the cursor always goes straight up or down when I press k or j, even when I’m going through long lines which wrap at the right end of the screen.
The next part is commented out, but I’m including it anyway because I still think it’s a useful feature:
"set list
"set listchars=tab:»·,trail:·
"hi SpecialKey ctermfg=cyan
This shows little arrows for tabs and dots at the end of lines with trailing spaces.
The next part makes the status line at the bottom of the windows a bit more populated:
set laststatus=2 "make a status line above the command line. otherwise this won't work
set statusline= "clear statusline
" set statusline+=%#comment# "make the statusline comment-color
set statusline+=%-3.3n\ " buffer number
set statusline+=%f\ " file name
set statusline+=%h%m%r%w " flags
set statusline+=[%{strlen(&ft)?&ft:'none'}, " filetype
set statusline+=%{strlen(&fenc)?&fenc:&enc}, " encoding
set statusline+=%{&fileformat}] " file format
set statusline+=%= " right align
set statusline+=%{synIDattr(synID(line('.'),col('.'),1),'name')}\ " highlight
set statusline+=%b,0x%-8B\ " current char
set statusline+=%-14.(%l,%c%V%)\ %<%P " offset
Here is my tabline:
function! MyTabLine()
let s = ''
let wn = ''
let t = tabpagenr()
let i = 1
while i <= tabpagenr('$')
let buflist = tabpagebuflist(i)
let winnr = tabpagewinnr(i)
let s .= '%' . i . 'T'
let s .= (i == t ? '%1*' : '%2*')
let s .= ' '
let wn = tabpagewinnr(i,'$')
let s .= (i== t ? '%#TabNumSel#' : '%#TabNum#')
let s .= i
if tabpagewinnr(i,'$') > 1
let s .= '.'
let s .= (i== t ? '%#TabWinNumSel#' : '%#TabWinNum#')
let s .= (tabpagewinnr(i,'$') > 1 ? wn : '')
end
for j in range(tabpagewinnr(i,'$')) " show a + if the tab contains modified buffers
let bufmodified = getbufvar(buflist[j], "&mod")
if bufmodified
let s .= '+'
endif
endfor
let s .= '%*'
let s .= (i == t ? '%#TabLineSel#' : '%#TabLine#')
let bufnr = buflist[winnr - 1]
let file = bufname(bufnr)
let buftype = getbufvar(bufnr, 'buftype')
if buftype == 'nofile'
if file =~ '\/.'
let file = substitute(file, '.*\/\ze.', '', '')
endif
else
if i != t
let file = fnamemodify(file, ':p:~:.:gs?\([^\/]\)[^\/]*\/?\1/?') " shorten path name to first letter of each directory
else
let file = fnamemodify(file, ':p:~:.')
endif
endif
if file == ''
let file = '[none]'
endif
let s .= file
" let s .= (i == t ? '%m' : '')
let i = i + 1
endwhile
let s .= '%T%#TabLineFill#%='
return s
endfunction
set showtabline=2 " always show tab line
set tabline=%!MyTabLine()
Most of the code for the tabline is from http://www.offensivethinking.org/data/dotfiles/vimrc.
It shows a nice tab line which shows tab numbers and the number of windows in a tab. I added the display of a path name which is shortened to the first letter of each directory when the tab is inactive. A also added the code that shows a little + in front of a tab name for each window in the tab which contains a modified buffer.
Next is more commented out code.
"set colorcolumn=80,120
"hi colorcolumn ctermbg=NONE ctermfg=red cterm=bold guibg=NONE guifg=red gui=bold
This highlights the 80th and 120th column of each line.
Since I'm mostly using gvim, except for quickly editing some config files, I also have a .gvimrc which sets guioptions=a.
I'm synchronizing these files on my netbook and desktop PC via Unison. Because I want to use different fonts and colorschemes on each computer, my .gvimrc ends with the line source ~/.gvimrc-local, and the .gvimrc-local, which is not synchronized, contains the font and colorscheme settings.
I hope my blog or your browser didn't eat too many of the angle brackets and other special characters in the code fragments.
