How do I get a list of functions defined in a module?

New to Julia

Is there a command in Julia 1.1 that lists all the methods that are available in a module?
e.g.

module MyMod
  test1() = 1
  test2() = 2
  test3() = 3
end

Which would return:

[test1,test2,test3]

I find this

names(x::Module; all::Bool = false, imported::Bool = false)

Get an array of the names exported by a Module , excluding deprecated names. If all is true, then the list also includes non-exported names defined in the module, deprecated names, and compiler-generated names. If imported is true, then names explicitly imported from other modules are also included.

As a special case, all names defined in Main are considered “exported”, since it is not idiomatic to explicitly export names from Main .

I get a 354-element vector. It is not completely shown on my console.

How can I get the long list complete.

show(stdout, "text/plain", somevector)

there is also the package TerminalPager which can be used like:

using TerminalPager
# [...]
somevector |> pager

I usually do foreach(println, x).

This is not the correct answer, because names() will export all names, not only those of the functions. How can I get only the names of the functions?

you could just filter all the names for beeing a function or not.

filter( x -> isa(getfield(module_name, x), Function), names(module_name))

# or

filter( x -> isa(getfield(module_name, x), Function), names(module_name; all=true))

Thanks! Now using:

function list_functions()
    fncs = filter( x -> isa(getfield(Main, x), Function), names(Main))
    for (i, fn) in pairs(fncs)
        println(fn)
        if (mod(i, 10)) == 0
            println("Press enter to continue...")
            readline()
        end
    end
end

Check also this alternative:

function list_functions(Module)
   fncs = filter(x -> isa(getfield(Module, x), Function), names(Module))
   foreach(x -> (println.(x); Base.prompt("\nENTER")), Iterators.partition(fncs, 10))
end
