"   You may direct issues regarding version 0.4+ to
"   Eric Van Dewoestine (ervandew@yahoo.com).
" Version: 0.41
" Description:
"   Use your tab key to do all your completion in insert mode!
"   The script remembers the last completion type, and applies that.
"   Eg.: You want to enter /usr/local/lib/povray3/
"   You type (in insert mode):
"   /u<C-x><C-f>/l<Tab><Tab><Tab>/p<Tab>/i<Tab>
"   You can also manipulate the completion type used by changing g:complType
"   variable.
"   You can cycle forward and backward with the <Tab> and <S-Tab> keys
"   (<S-Tab> will not work in the console version)
"   Note: you must press <Tab> once to be able to cycle back
" History:
"   0.41 Fixed couple bugs introduced in last version (Eric Van Dewoestine).
"   0.4  Added the following functionality (Eric Van Dewoestine)
"        - support for vim 7 omni, user, and spelling completion modes
"          (should be backwards compatible with vim 6.x).
"        - command :SuperTabHelp which opens a window with available
"          completion types that the user can choose from.
"        - variable g:SuperTabRetainCompletionType setting for determining if
"          and for how long to retain completion type.
"   0.32 Corrected tab-insertion/completing decidion (thx to: Lorenz Wegener)
"   0.31 Added <S-Tab> for backward cycling. (req by: Peter Chun)
"   0.3  Back to the roots. Autocompletion is another story...
"        Now the prompt appears, when showmode is on

if !exists('complType') "Integration with other completion functions...

  " This variable determines if, and for how long, the current completion type
  " is retained.  The possible values include:
  " 0 - The current completion type is only retained for the current completion.
  "     Once you have chosen a completion result or exited the completion
  "     mode, the default completion type is restored.
  " 1 - The current completion type is saved for the duration of your vim
  "     session or until you enter a different completion mode.
  "     (SuperTab default).
  " 2 - The current completion type is saved until you exit insert mode (via
  "     ESC).  Once you exit insert mode the default completion type is
  "     restored.
  if !exists("g:SuperTabRetainCompletionType")
    let g:SuperTabRetainCompletionType = 1
  endif

  " This variable is used to set the default completion type.
  " There is no need to escape this value as that will be done for you when
  " the type is set.

  if !exists("g:SuperTabDefaultCompletionType")
    let g:SuperTabDefaultCompletionType = "<C-P>"
