It might also be better to go to the '. mark instead of leaving it where it
ends up, if you DID make a change, so you're going back to the last place
where a change was actually made rather than just where the cursor was when
you closed the file, in case you moved around a bit after making a change.
This isn't what was asked, but I like to ignore the mark when opening
certain files and go to a specific place in the file rather than where the
cursor was, so I use this (legacy Vim script because I wrote it over a many
years ago):
let g:noRestorePositionList = {}
let g:noRestorePositionList[ 'COMMIT_EDITMSG' ] = 'top'
let g:noRestorePositionList[ 'bugs\.vim' ] = 'bottom'
let g:noRestorePositionList[ '.*\.money' ] = 'ignore'
function! GoToLastEditedPosition()
let filename = expand( "%:t" )
let matchFound = 0
let position = ''
for key in keys( g:noRestorePositionList )
if ( filename =~? key )
let matchFound = 1
let position = g:noRestorePositionList[ key ]
endif
endfor
if ( matchFound )
" Can't just execute 1 or $ because we don't just want to go to the
line, but rather the beginning of the line
if ( position == 'top' )
normal! gg0
elseif ( position == 'bottom' )
normal! G0
endif
" Ignore empty value or if the value is 'ignore'.
return
endif
let lastLine = line( "'\"" )
if ( lastLine > 0 && lastLine <= line( '$' ) )
" Go to the last cursor location and center it on the screen
normal! g`"zz
endif
endfunction
augroup lastedit
" Go to the last edited position if it's valid and move it to the middle
of the screen
au BufReadPost * call GoToLastEditedPosition()
augroup END
