Here is user-defined RENAME command that seems to work::command! -narg=1 RENAME if rename(expand('%'),<q-args>)==0|file <args>|else| echo "Renaming error"| endif
Thanks! I'll give it a try...
The :rename command is in the todo list. (':help todo', search for :rename).
Oh, i see, kudos to developers for their hard work! -- Best regards, Pavel
