I've setup my vim editor (I use MacVim) to save files automatically when the focus is lost:
autocmd FocusLost * silent! wall
I also automatically strip trailing whitespace from python files using this auto command:
autocmd BufWritePre *.py :%s/\s\+$//e
This auto command works perfectly when I save the file manually (either by typing :w or by pressing ⌘s) but it is not executed (i.e. the whitespace is not stripped) when I switch to another application and the buffer is automatically written.
How can I modify these auto commands to make them work together?
You need to change your FocusLost autocommand to:
autocmd FocusLost * nested silent! wall
See :h autocmd-nested for details.
I can't test this in a graphic Vim, but you can try some options:
- Join some events in the same autocommand
autocmd BufWritePre,FocusLost *.py ... - Execute an autocommand from an event, something like:
autocmd BufWritePre *.py :execute "%s/\s\+$//e" | doautocmd FocusLost %
