/**
|
|
* A helper function parsing provided command line arguments and handling two
|
|
* specific args:
|
|
*
|
|
* -MOZ_LOG=modulelist
|
|
* -MOZ_LOG_FILE=file/path
|
|
*
|
|
* both expecting an argument, and corresponding to the same-name environment
|
|
* variables we use for logging setup.
|
|
*
|
|
* When an argument is found in the proper form, the consumer callback is called
|
|
* with a string in a follwing form, note that we do this for every occurence,
|
|
* and not just at the end of the parsing:
|
|
*
|
|
* "MOZ_LOG=modulelist" or "MOZ_LOG_FILE=file/path"
|
|
*
|
|
* All the following forms of arguments of the application are possible:
|
|
*
|
|
* --MOZ_LOG modulelist
|
|
* -MOZ_LOG modulelist
|
|
* --MOZ_LOG=modulelist
|
|
* -MOZ_LOG=modulelist
|
|
*
|
|
* The motivation for a separte function and not implementing a command line
|
|
* handler interface is that we need to process this very early during the
|
|
* application startup. Command line handlers are proccessed way later
|
|
* after logging has already been set up.
