3.4. Functions from other modules and imports

Suppose that we have a module foo.Bar:

module foo.Bar

function f = {
  return "f()"
}

We can invoke f from another module by prefixing it with its module name:

let r = foo.Bar.f()

Of course, we may also take advantage of an import statement:

module Somewhere.Else

import foo.Bar

function plop = {
  return f()
}

Note

Imports in Golo do not work as in Java. Golo is a dynamic language where symbols are being resolved at runtime. Module imports are not checked at compilation time, and their sole purpose is to help in dynamic resolution. Back to the previous example, f cannot be resolved from the current module, and the Golo runtime subsequently tries to resolve f from each import statement. Also, note that the order of import statements is important, as the resolution stops at the first module having the f function.

Last but not least, you may prepend the last piece of the module name. The following invocations are equivalent:

module Somewhere.Else

import foo.Bar

function plop = {
  let result = f()
  let result_bis = Bar.f()
  let result_full = foo.Bar.f()
  return result
}

Golo modules have a set of implicit imports:
