Consistent log level with `Async.Std.Log.Global` across different modules

[Dominik Gabi]

Hi All,

potential dummy question: I'm playing with async and I have several modules from which I want to log. So in module `A` I have something along the lines of 

  open Async.Std

  module Log = Log.Global

  ...

  Log.set_level (if verbose then `Debug else `Info);

  Log.debug "blah";

and if I pass a `-verbose` option to my binary I get all the debug output. However, if I call `Log.debug` from module `B` (after the above code has been executed) the output is swallowed unless I call `set_level` again. Am I missing something here? Do I have to pass my `verbose` flag to every module in my program and re-initialize the logging module?

Thanks,

Dominik

It should work. It's hard to know why it's not without looking at your code in more detail. Although I will mention that most of the time, one does this kind of logging setup in the "main" function of your program, rather than at the module top-level as it looks like you are doing here.
