• Command stdout redirection

  :! # get last output redir @a echo toto redir END let @a=getcwd()

• Random, Sort, Shuffle
  • Random shuffle :10,20!shuf func Random() return reltimestr(reltime())[-2:] endfunc %s/^/=Random() . ""/|sort n|%s/^//

• Remote

  vim –servername DEMO vim –servername DEMO –remote file.txt vim –servername DEMO –remote-send “:3d” :!vim –servername DEMO –remote-tab “%” " Send current buffer to remote vim

• File format
  • :e ++ff=unix
  • :w ++ff=dos
  • %s/\r\n/
• Buffer
  • :b *.java<c-d> : list buffer names matching regex
• Pipeline
  • echo toto | vim - : take arguments from stdin
  • echo foo | vim -e '+%print' '+q!' /dev/stdin : exmode to not consume stdin and not clear output on quit
  • vim <(echo toto) : process substitution command (BaSh)
  • :w !tee : write to stdout
• Script : Get filetype of a buffer
  • :let bufFiletype = getbufvar(bufNr, '&filetype')
• Substitute without escaping the replcement
  • :%sno/search_string/replace_string/g
  • :s/</\='&lt;'/g
• Delete everything except text
  • :%s/\(^\|\(text\)\@<=\).\{-}\($\|text\)\@=//g

  • \(^\|\(text\)\@<=\)     # means start of line, or some point preceded by “text”
    .\{-}                   # as few characters as possible
    \($\|text\)\@=          # without globbing characters, checking that we reached either end of line or occurrence of “text”.

  • Another way to do it:

  • Create a function that count matches of a pattern in a string (see :help match() to help you design that)

  • Use: :%s/.*/=repeat(‘text’, matchcount(‘text’, submatch(0)))

• Find where root runtime is
  • :echo $VIMRUNTIME -> /usr/share/vim/vim74
• Source autoload file
  • :call example#BadFunction()
• Find where a map has been defined (in which script)
  • :verbose map <c-z>

• Use s/\%V to substitude within selection and not full lines

• Remember manual folds
  • au BufWinLeave ?*mkview
  • au BufWinEnter ?* silent loadview
