Question

I’d like to call the VCSStatus function passing the current working directory (whatever :pwd returns) to it. It has to be the full path, and no special characters such as “.” are accepted.

Answer 1

:execute 'VCSStatus' getcwd()

should do the trick. Should you wish to use the current file’s directory instead, it’d be:

:execute 'VCSStatus' expand('%:p:h')

(% refers to the current file, :p modifies to a full absolute path, and :h cuts off the filename; cp. :help filename-modifiers)
