It can alternatively be thought of as -" a template expander. -" -" 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. -" -" If, in order to take care of the above problems, you do instead -" -" iab lhs something -" -" then the timeout problem is solved and so is the problem of mistyping. -" however, abbreviations are only expanded after typing a non-word character. -" which causes problems of cursor placement after the expansion and invariably -" spurious spaces are inserted. -" -" Usage Example: -" this script attempts to solve all these problems by providing an emulation -" of imaps wchich does not suffer from its attendant problems. Because maps -" are activated without having to press additional characters, therefore -" cursor placement is possible. furthermore, file-type specific indentation is -" preserved, because the rhs is expanded as if the rhs is typed in literally -" by the user. -" -" The script already provides some default mappings. each "mapping" is of the -" form: -" -" call IMAP (lhs, rhs, ft) -" -" Some characters in the RHS have special meaning which help in cursor -" placement. -" -" 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. -" -" NOTE: 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 hoders. -" -" 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>", '') -" -" sets up the map for date` to insert the current date. -" -"--------------------------------------%<-------------------------------------- -" Bonus: This script also provides a command Snip which puts tearoff strings, -" '----%<----' above and below the visually selected range of lines.
