AUTOCOMMANDS *dirvish-autocommands*

DirvishShdoCreated *User_DirvishShdoCreated*
A |User| |autocommand| invoked after creating a |:Shdo| buffer.
b:dirvish_dir is set to the previous Dirvish buffer's path.

To ensure scripts always cd to the current dirvish directory, you could
add this to your vimrc: >

autocmd User DirvishShdoCreated call OnShdoCreated()
function! OnShdoCreated() abort
if has('win32')
" work across hard drives
let chdir = 'pushd '
else
let chdir = 'cd '
endif
call append(0, [chdir .. b:dirvish_dir, ''])
