- IMAP -- A fluid replacement for :imap
- *imaps.txt*

- Abstract
- ========
-This plugin provides a function IMAP() which emulates vims |:imap| function. The
-motivation for providing this plugin is that |:imap| suffers from problems
-which get increasingly annoying with a large number of mappings.
-
-Consider an example. If you do >
- imap lhs something
-
-
-then a mapping is set up. However, there will be the following problems:
-1. The 'ttimeout' option will generally limit how easily you can type the lhs.
- if you type the left hand side too slowly, then the mapping will not be
- activated.
-
-2. If you mistype one of the letters of the lhs, then the mapping is deactivated
- as soon as you backspace to correct the mistake.
-
-3. The characters in lhs are shown on top of each other. This is fairly
- distracting. This becomes a real annoyance when a lot of characters initiate
- mappings.
-
-This script provides a function IMAP() which does not suffer from these
-problems.

-================================================================================
-Viewing this file
-
-This file can be viewed with all the sections and subsections folded to ease
-navigation. By default, vim does not fold help documents. To create the folds,
-press za now. The folds are created via a foldexpr which can be seen in the
-last section of this file.
-
-See |usr_28.txt| for an introduction to folding and |fold-commands| for key
-sequences and commands to work with folds.
-
-================================================================================
-Using IMAP *im_1* *imaps-usage*
-
-
-
-Each call to IMAP is made using the syntax: >
- call IMAP (lhs, rhs, ft [, phs, phe])
-
-
-This is equivalent to having <lhs> map to <rhs> for all files of type <ft>.
-
-Some characters in the <rhs> have special meaning which help in cursor placement
-as described in |imaps-placeholders|. The optional arguments define these
-special characters.
-
-Example One: >
- call IMAP ("bit`", "\\begin{itemize}\<cr>\\item <++>\<cr>\\end{itemize}<++>", "tex")
-
-
-This effectively sets up the map for "bit`" whenever you edit a latex file. When
-you type in this sequence of letters, the following text is inserted: >
- \begin{itemize}
- \item *
- \end{itemize}<++>
-
-where * shows the cursor position. The cursor position after inserting the text
-is decided by the position of the first "place-holder". Place holders are
-special characters which decide cursor placement and movement. In the example
-above, the place holder characters are <+ and +>. After you have typed in the
-item, press <C-j> and you will be taken to the next set of <++>'s. Therefore by
-placing the <++> characters appropriately, you can minimize the use of movement
-keys.
-
-Set g:Imap_UsePlaceHolders to 0 to disable placeholders altogether.
-
-Set g:Imap_PlaceHolderStart and g:Imap_PlaceHolderEnd to something else if you
-want different place holder characters. Also, b:Imap_PlaceHolderStart and
-b:Imap_PlaceHolderEnd override the values of g:Imap_PlaceHolderStart and
-g:Imap_PlaceHolderEnd respectively. This is useful for setting buffer specific
-place holders.
-
-Example Two: You can use the <C-r> command to insert dynamic elements such as
-dates. >
- call IMAP ('date`', "\<c-r>=strftime('%b %d %Y')\<cr>", '')
-
-
-
-With this mapping, typing date` will insert the present date into the file.

-About this file
-
-This file was created automatically from its XML variant using db2vim. db2vim is
-a python script which understands a very limited subset of the Docbook XML 4.2
-DTD and outputs a plain text file in vim help format.
-
-db2vim can be obtained via anonymous CVS from sourceforge.net. Use
-
-cvs -d:pserver:anonymous@cvs.vim-latex.sf.net:/cvsroot/vim-latex co db2vim
-
-Or you can visit the web-interface to sourceforge CVS at:
-http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/vim-latex/db2vim/
-
-The following modelines should nicely fold up this help manual.
