VIM - HVboom/HowTo-DigitalOcean GitHub Wiki

Vim is a highly configurable text editor built to enable efficient text editing. It is an improved version of the vi editor distributed with most UNIX systems.

Vim is often called a "programmer's editor," and so useful for programming that many consider it an entire IDE. It's not just for programmers, though. Vim is perfect for all kinds of text editing, from composing email to editing configuration files.

Despite what the above comic suggests, Vim can be configured to work in a very simple (Notepad-like) way, called evim or Easy Vim.

• This script is automatically copied to the user directory, if it does not exists (see /usr/local/share/bash/profile)

  ...
  # copy default VIM options
  if [ ! -e "$HOME/.vimrc" ]
  then
    cp "$globalSettings/.vimrc" "$HOME"
  fi
  ...

• The editor is automatically used as a substitution von VI (see /usr/local/share/bash/.alias)

  ...
  # use VIM, if installed
  if [ -x `which vim` ]
  then
    alias vi='vim'
    alias view='vim -R'
  fi
  ...

• You can edit the copied version, e.g. to trim trailing spaces of ruby files on save

  ...
  autocmd BufWritePre *.rb :call TrimWhiteSpace()
