[julia-users] interpolation: variable not defined

[Tamas Papp]

I am trying to write a simple utility that opens the readme of a package
in my browser:

@doc "Open readme of package in browser."->
function Pkgreadme(package)
  file = Pkg.dir(package) * "/" * "README.md"
  isfile(file) && `x-www-browser $(file)`
end

but get the error

ERROR: UndefVarError: file not defined

when evaluating. I must have misunderstood something about
interpolation, but can't find a solution to this, even after checking
the archives. v"0.4.0-dev+4160".

Best,

Tamas
