What's wrong with these filter command definitions?

Question

1. command fil filter! (важность-(важное|неважное-topics)|срочность-(не)\?срочное)$
2. command fil filter!/(важность-(важное|неважное-topics)|срочность-(не)\?срочное)$/

Both full commands result in "Add bang to force".

1. The part after "fil " of the first command (with a space) alone works.
2. The part after "fil " of the second command (without a space) says "Invalid command name". I guess that's because the unescaped "|" is not considered part of the regexp. But doesn't that contradict the manual, which says "Using second variant you can use the bar ('|') symbol without escaping."?

For vimrc, Vifm says "Error in …/.config/vifm/vifmrc at line 4" instead of any of the messages above.

Answer 1

fil is a short name of :f[ile], so there is a conflict. You can't redefine :file and not sure if redefining :fil should be allowed.

filter!/(важность-(важное|неважное-topics)|срочность-(не)\?срочное)$/

Would work with a space after ! before, works without it now. It was a bug, thanks.

For vimrc, Vifm says "Error in …/.config/vifm/vifmrc at line 4" instead of any of the messages above.

Yeah, status bar should display actual error while dialog is visible, but that doesn't work out well in all cases (so would be better to display error in dialog).

Thanks, now the second filter works (and the "?" must not be escaped in it because of the slashes).
