for example,

I have the module:

```julia
module Foo

  bar() = println("moo")
  baz() = 404

  a = 2
  b = 3.4e2
  c = a + b / baz()

end

```

how do i get a dictionary that looks like:

```julia
{
  a: 2
  b: 3.4e2
  c: 2.8415841584
}

```

// note this dictionary ignores (direct definitions of) `bar` and `baz`

Dict{Symbol,Real} with 3 entries:

Do not use `eval` here, use `getfield` instead.

Ah, good point. I actually didn’t know about using `getfield` with a module.

This works too:

```julia
julia> Dict(s=>getfield(Foo, s) for s in names(Foo, true) if s != :Foo && s != :eval && !isa(getfield(Foo, s), Function) && !startswith(string(s), "#"))
Dict{Symbol,Real} with 3 entries:
  :c => 2.84158
  :a => 2
  :b => 340.0

```

that’s awesome!

is `s != :eval` needed, though?

it looks like `!startswith(string(s), "#"))` catches that.

were you just trying to be explicit?

It’s probably just an artifact of the order in which I added the checks while figuring it out. I’m not surprised that one of them is redundant.

</div>

the code I got working with my project was:

`Dict(s=>getfield(Foo, s) for s in names(Foo, true) if s != :Foo && !startswith(string(s), "#") && !startswith(string(s), "/") && !isa(getfield(Foo, s), Function) && !isa(getfield(Foo, s), Type) && !isa(getfield(Foo, s), Module))`

beyond original question, this also ignores:

- macros
- types
- modules
- loaded files
