Use this code to highlight the cursor line after a jump. This makes it easy to spot the new cursor position. The highlight will be removed automatically when you move the cursor within the current line, or down or up by one line.
function s:Cursor_Moved() let cur_pos = winline() if g:last_pos == 0 set cul let g:last_pos = cur_pos return endif let diff = g:last_pos - cur_pos if diff > 1 || diff < -1 set cul else set nocul endif let g:last_pos = cur_pos endfunction autocmd CursorMoved,CursorMovedI * call s:Cursor_Moved() let g:last_pos = 0

TO DO
- Should use autogroup and remove old autocmd when source again.
- Need WinEnter autocmd?
- Nice if could handle split windows reasonably (highlight when enter split).
If you want the current line highlighted when moving even by one line, use:
if diff >= 1 || diff <= -1
instead of
if diff > 1 || diff < -1
If you still want to be able to manually set the cursor line:
In your autocmd section:
let g:manual_cursor = 0
Create a mapping to manually toggle the cursorline and set a global var for the function to check:
nnoremap <silent> <LocalLeader>tc :set invcul cul?<CR>:let g:manual_cursor=&cul<CR>
In the function definition:
if g:manual_cursor return endif
Then, \tc
in normal mode allows you to toggle a persistent or transient cursorline ('tc' is a mnemonic for "toggle cursor").
By default, in a cterm, this highlights the current line by underlining it. Is it possible to highlight some other way, e.g. by changing the background colour of that line, or formatting the line's text in bold?
- The format of the highlight can be set using 'hi CursorLine', eg. 'hi cursorline cterm=bold ctermbg=grey'
It is probably better to use
setlocal cul
and
setlocal nocul
to only change the setting for the buffer you're working in. Also, for some "special" buffers you may add the following code at the beginning of the function to avoid changing the setting (the following skips the function for the NERDTree window):
if bufname ('%') =~ '^NERD_tree_' return endif
(Or check for some buffer-local variable and skip based on that...)
