[Mono-list] Diagnostic Messages

[Jonathan Pryor]

Interesting idea, but it's been my experience that environment variables
can lead to confusion *if* there isn't an analogous way to invoke that
functionality directly on the command line.

So both a MONO_TRACE environment variable and a --diagnostics argument
might be useful.

    I think the Trace and Debug facilities you want can be easily supported
    with and environment variable: the code will look it up and set the
    filestream where the output should go:
    
    export MONO_TRACE=debug,trace=/dev/null
    
    would mean that debug is enabled (and the output goes to stderr) and
    trace is enabled and the output goes to the file named /dev/null.
    If either debug or trace is not mentioned in the var or if it's not set,
    you get no output. This is a runtime library issue, so there should be
    no switches for it in mono/mint.
    Anyone that wants to submit a patch to implement this?
    
    That said, I don't think the Debug and Trace classes should be used in
    the libraries (certainly not in corlib).
