Hello all,
I have been using the following hack to remove trailing whitespace:
autocmd BufWritePre,FileWritePre * call StripTrailingWhitespace()
function! StripTrailingWhitespace()
normal mz
normal Hmy
exec '%s/\s*$//g'
normal 'yz<cr>
normal `z
endfunction
However, that has several negative side-effects - e.g. messing with
the undo stack and sometimes altering the cursor position.
I have read through various discussions and guides*, but haven't found
a better solution so far.
This seems like a common issue (even though some might argue doing
this automatically is wrong), so I was wondering whether there was a
canonical solution I might have missed?
Any tips would be greatly appreciated!
