ex - Vim command for "edit a copy of this file" -

-

a pattern seem following right is:

  • edit file until it
  • :w another-file use starting point another-file
  • :e another-file polish another-file

is there existing ex command latter 2 steps @ once? :writeandedit another-file?

i can fake 1 using vimscript, want know if there's existing command.

could :saveas job?

:sav[eas][!] [++opt] {file}             save current buffer under name {file} , set             filename of current buffer {file}.              previous name used alternate file name.

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
