1 " Author: Gergely Kontra <kgergely@mcl.hu>
2 " You may direct issues regarding version 0.4+ to
3 " Eric Van Dewoestine (ervandew@yahoo.com).
4 " Version: 0.41
5 " Description:
6 " Use your tab key to do all your completion in insert mode!
7 " The script remembers the last completion type, and applies that.
8 " Eg.: You want to enter /usr/local/lib/povray3/
9 " You type (in insert mode):
10 " /u<C-x><C-f>/l<Tab><Tab><Tab>/p<Tab>/i<Tab>
11 " You can also manipulate the completion type used by changing g:complType
12 " variable.
13 " You can cycle forward and backward with the <Tab> and <S-Tab> keys
14 " (<S-Tab> will not work in the console version)
15 " Note: you must press <Tab> once to be able to cycle back
16 " History:
17 " 0.41 Fixed couple bugs introduced in last version (Eric Van Dewoestine).
18 " 0.4 Added the following functionality (Eric Van Dewoestine)
19 " - support for vim 7 omni, user, and spelling completion modes
20 " (should be backwards compatible with vim 6.x).
21 " - command :SuperTabHelp which opens a window with available
22 " completion types that the user can choose from.
23 " - variable g:SuperTabRetainCompletionType setting for determining if
24 " and for how long to retain completion type.
25 " 0.32 Corrected tab-insertion/completing decidion (thx to: Lorenz Wegener)
26 " 0.31 Added <S-Tab> for backward cycling. (req by: Peter Chun)
27 " 0.3 Back to the roots. Autocompletion is another story...
28 " Now the prompt appears, when showmode is on
29
30 if !exists('complType') "Integration with other completion functions...
31
32 " This variable determines if, and for how long, the current completion type
33 " is retained. The possible values include:
34 " 0 - The current completion type is only retained for the current completion.
35 " Once you have chosen a completion result or exited the completion
36 " mode, the default completion type is restored.
37 " 1 - The current completion type is saved for the duration of your vim
38 " session or until you enter a different completion mode.
39 " (SuperTab default).
40 " 2 - The current completion type is saved until you exit insert mode (via
41 " ESC). Once you exit insert mode the default completion type is
42 " restored.
43 if !exists("g:SuperTabRetainCompletionType")
44 let g:SuperTabRetainCompletionType = 1
45 endif
46
47 " This variable is used to set the default completion type.
48 " There is no need to escape this value as that will be done for you when
49 " the type is set.
