I tried printing something to the debug log, but I see no output:
julia> @debug "foo"
How can I enable debug output?

To see the debug output window, in Microsoft Visual Studio, click View, click Other Windows, and then click Output. You can view the debug output in this window only if the debugger is attached to the process that is writing to the output window.
Navigate to Event Viewer (Local)\Applications and Service Logs\Microsoft\User Experience Virtualization\App Agent. Right-click on Debug under App Agent and select Enable Log. Select OK when presented with the "Analytic and Debug logs may lose events when they are enabled.
Debug Output is an OpenGL feature that makes debugging and optimizing OpenGL applications easier. Briefly, this feature provides a method for the driver to provide textual message information back to the application.
Use the JULIA_DEBUG environment variable to set debug output.
Set the value to the name of the module for which you want to enable debug logging:
julia> ENV["JULIA_DEBUG"] = Base
For the case of @debug calls in the REPL, set the module to Main:
julia> ENV["JULIA_DEBUG"] = Main
Main
julia> @debug "foo"
┌ Debug: foo
└ @ Main REPL[6]:1
The special all value will enable debug logging for all modules:
julia> ENV["JULIA_DEBUG"] = "all"
If want to enable debugging during startup, you can set it through the shell:
$ JULIA_DEBUG=all julia
