I'm trying to cut string returned from fugitive plugin. It returns branch name of current file. By default returned string is Git(branchname) and this is why I want to get rid of odd Git(..) wrapper. So here is the code:

set statusline+=%{strpart(fugitive#statusline(), 4, 1)}

When I update .vimrc it returns error:

E540: Unclosed expression sequence: statusline+=%{strpart(fugitive#statusline(), 

What do I wrong?


Values used in :set are strings. See :h set-args:

                                                :set-args E487 E521
:se[t] {option}={value}         or
:se[t] {option}:{value}
                        Set string or number option to {value}.
                        White space between {option} and '=' is allowed and
                        will be ignored.  White space between '=' and {value}
                        is not allowed.
                        See option-backslash for using white space and
                        backslashes in {value}.

You should escape the spaces:

set statusline+=%{strpart(fugitive#statusline(),\ 4,\ 1)}

Consider the example from the help for fugitive#statusline:

set statusline=%<%f\ %h%m%r%{fugitive#statusline()}%=%-14.(%l,%c%V%)\ %P

Note how all the spaces (all two of them, anyway) are escaped.


strpart(x, 4, 1) is a single character, which is probably not what you wanted. split() might be more useful:

:echo strpart(fugitive#statusline(),4,1)
:echo split(fugitive#statusline(), '[()]')[1]

So, you probably want:

set statusline+=%{remove(split(fugitive#statusline(),'[()]'),1)}

This will error out outside git repositories. It might better to write a small function at this point:

function! Current_git_branch()
    let l:branch = split(fugitive#statusline(),'[()]')
    if len(l:branch) > 1
         return remove(l:branch, 1)
    return ""

And then:

set statusline+=%{Current_git_branch()}

    Hm...:echo split(fugitive#statusline(), '[()]')[1] works perfectly, but when I place the last line you suggested set statusline+=%{... it returns error: E684: list index out of range: 1. What's wrong!?(( – Timur Fayzrakhmanov Feb 16 '16 at 10:42

    @TimurFayzrakhmanov are you running it in a window whose directory is not in Git? I get that error if I'm not in a git repository. – muru Feb 16 '16 at 10:53
  • Right! And it always append "0" if a file isn't in git repo. Can you please suggest how to prevent this error (I mean place nothing if the file isn't in git repo)? – Timur Fayzrakhmanov Feb 16 '16 at 10:57
  • @TimurFayzrakhmanov see update. – muru Feb 16 '16 at 11:11
