" File: multiple_cursors.vim
|
|
" Author: Terry Ma
|
|
" Description: Emulate Sublime Text's multi selection feature
|
|
" Issues:
|
|
" - Performance in terminal vim degrades significantly with more cursors
|
|
" - All user input typed before Vim is able to fan out the last operation to all
|
|
" cursors is lost. This is a implementation decision to keep the input
|
|
" perfectly synced in all locations, at the cost of potentially losing user
|
|
" input.
|
|
" - Multi key commands is not supported
|
|
" - Single key commands that do not terminate properly cause unexpected
|
|
" behavior. For example, if the cursor is on the first character in the buffer
|
|
" and 'b' is pressed.
|
|
" - Undo behavior is unpredictable
|
|
" - Select mode is not implemented
|
|
" - There is a bug with selection and highlight when wrap is on
|
|
"
|
|
" Potential Features:
|
|
" - Create a blinking cursor effect? Good place to do it would be instead of
|
|
" waiting for user input, cycle through the highlight
|
|
" - Integrate with the status line? Maybe show a special multicursor mode?
|
|
" - Support mouse? Ctrl/Cmd click to set cursor?
|
|
"
|
|
" Features:
|
|
" - Real time update of cursor locations
|
|
" - In normal mode, pressing <C-n> will highlight the current word under cursor,
|
|
" and places a 'multicursor' at the end of the word, and goes to visual mode
|
|
" - In visual mode, right after the above operation, pressing <C-n> again will
|
|
" search for the word forward, and places a new cursor at the end of the
|
|
" resulting search, one can continue to do this in Visual mode, this resembles
|
|
" the Cmd-D feature of Sublime
|
|
" - In insert mode, insert operations are captures and replayed at all the
|
|
" cursor locations
|
|
" - Pressing <Esc> in Normal mode quits multicursor mode and clears all cursors
|
|
" - Normal mode single keystroke commands work:
|
|
" - Works: 'w,e,i,p,a,h,j,k,l,x,v,b'
|
|
" - Does not work: ''
|
|
" - Replace mode just seems to work
|
|
" - Visual mode
|
|
" - Works: 'w,e,b,h,j,k,l,o'
|
|
" - Does not work: 'A, I', because <C-o> does not get it out of normal mode
|
|
" for these commands. It takes two
