Mute log record emission through Environment Variables

[marcellodesales]

Hi there,

I was looking for a way to disable a given record to be emitted depending on its value. Is this possible???

My requirement is as follows:

Component A

• require("bunyan");

Component B

• Is composed by Component A
• require("bunyan");

Components A and B have their own logging settings. Considering Component A is a shared library, I want to be able to disable records to be logged from Component B, depending on the properties of the logs from Component A, say, "component".

I'm thinking about something like this... Given the record:

{ name: "my app",
   component: "componentA"
   ...
}

I want to be able to remove disable the logging specifically from this using environment variables on Component B like the one below:

{{{
process.env.BUNYAN_DISABLE_REC_component = "ComponentA".
}}}

thanks!
Marcello

Just noticed that the current version of the pull request may interfere with matching records from any app. I'm thinking I can add a prefix for the "name" of used for the record.

process.env.BUNYAN_DISABLE_REC_myapp.component=web

Where:

• myapp = is the record.name value
• component = is the record.component value.

That way, we can restrict the value that is "muted".

Thanks for the issue. See my comments on #176.
