Is there a simple way to find out from where a module is imported? I.e. something like

```julia
using Foo
path(Foo)

```

```julia
Pkg.dir("Foo")

```

or

```julia
using Foo
Pkg.dir(string(Foo))

```

should do it.

This works only for packages that are installed by the package manager. In fact the package doesn’t even have to be installed - it just returns the directory + the given name:

```julia
julia> Pkg.dir("abcde123")
"/home/sebastian/.julia/v0.5/abcde123"

```

I also want to handle the case where the module is loaded from somewhere else via LOAD\_PATH.

Assuming the module folder follows the standard structure and also that the module defines or extends at least one function this should work:

```julia
function moduleloc(M::Module)
    for n in names(M, true, true)
        if isdefined(M, n) && getfield(M, n) isa Function
            f = getfield(M, n)
            ms = Iterators.filter(m-> m.module==M, methods(f))
            if !isempty(ms)
                dir = join(split(string(first(ms).file), "/")[1:end-1], "/")
                return dir
            end
        end
    end
    return ""
end

```

</div>

Based on this, but simpler and more robust, consider

```julia
dirname(dirname(Base.functionloc(Foo.eval, Tuple{Void})[1]))

```

This assumes that the module was declared with `module` rather than `baremodule`, and uses the fact that the `module Foo` line is the one credited for the definition of the `Foo.eval` function (which is defined for all `module`s).

Thank you both very much for taking the time to even implement these functions for me!
