Select a directory in vim and use it's name in function call

Question

Inside a vim function I would like to have the user select a directory (instead of writing its name), I guess using :Explore, then get the filename of that directory and pass it to another function for example.

E.g. something like this

function! Test()
    let directory = ????
    call Test2(directory)
endfunction

Answer 1

This can be achieved with the browsedir() function:

function! Test()
   let initialDir = '/home/'
   let directory = browsedir('my prompt title', initialDir)
   echo "directory = ".directory
endfunction
