Wait for Node.connect before using :global.whereis_name


Tag: erlang,elixir

I have the following function:

  def join(id) do
    if Node.connect(:"#{id}@") do
      send :global.whereis_name(id), {:join, id}

I receive the error:

(ArgumentError) argument error
               :erlang.send(:undefined, ...

which I assume is because Node.connect does some gathering of information and when I call :global.whereis_name it has not finished yet. If I throw in a :timer.sleep(1000) sure enough I don't get an error. Is there a more elegant solution? I would like repeat :global.whereis_name until successful or a timeout is reached.


I should mention that I already have a node registered with the name id.


You could do a :global.sync() before :global.whereis_name(id)


How to delete a Phoenix Session?

I'm going through the Phoenix Guide on Sessions.

From the guide: defmodule HelloPhoenix.PageController do use Phoenix.Controller def...

Importing test code in elixir unit test

Erlang syntax error unclear

I just got started with Erlang. I am trying if statement. I found out one particular behavior which I do not understand. the following statement does work perfectly. some_comp(Arg1) -> if (cal(Arg1)>50000)->'reached'; true -> 'invalid' end. cal(Arg2)-> %% some calculation. However the following shows an error syntax near if: some_comp(Arg1)...

Erlang: Returning a function from a function

What is the number that shows up after you define an anonymous function in elixir?

When you define an anonymous function in elixir you get a result like this. #Function<6.90072148/1 in :erl_eval.expr/5> What I've noticed is that the number is based on the arity of the function. So a 1 arg function is always #Function<6.90072148/1 in :erl_eval.expr/5> A two arg function is always #Function<12.90072148/2 in...

Does the pattern [_|_] in Erlang mean anything specific?

I am learning Erlang from Learn You Some Erlang and I've seen the pattern [_|_] twice already but couldn't find any info on it. This usage seems superfluous because omitting it from (1) and subsituting it with _ in (2) yields the same result without degrading readability. It is my...

Erlang pass-by-reference nuances

9> A = lists:seq(1,10). [1,2,3,4,5,6,7,8,9,10] 13> Fn = fun (L) -> [0|L] end. #Fun<erl_eval.6.90072148> 14> Fn(A). [0,1,2,3,4,5,6,7,8,9,10] 15> A. [1,2,3,4,5,6,7,8,9,10] If erlang internally passes by reference (see this), why does the value of A not reflect the change? What fundamental am I missing about passing-by-reference or erlang?...
