After some tinkering, I came up with this version, which attempts to
expand tokens mentioned in ':he cmdline-special' before moving the
cursor to the scratch buffer:
command! -complete=shellcmd -nargs=+ Shell call s:RunShellCommand(<q-args>)
function! s:RunShellCommand(cmdline)
echo a:cmdline
let expanded_cmdline = a:cmdline
for part in split(a:cmdline, ' ')
if part[0] =~ '\v[%#<]'
let expanded_part = fnameescape(expand(part))
let expanded_cmdline = substitute(expanded_cmdline, part,
expanded_part, '')
endif
endfor
botright new
setlocal buftype=nofile bufhidden=wipe nobuflisted noswapfile nowrap
call setline(1, 'You entered: ' . a:cmdline)
call setline(2, 'Expanded Form: ' .expanded_cmdline)
call setline(3,substitute(getline(2),'.','=','g'))
execute '$read !'. expanded_cmdline
setlocal nomodifiable
1
endfunction
It likely has problems of its own. It assumes everything that will be
expand()'ed will result in a file name, for one thing. However, I can
get trivial buffer name expansions to work, so I'm happy.
