Version: SMASH-2.2
Logging Classes and Functions

The interfaces in this group are used for debug and informational console output.

SMASH uses the einhard logging library for debug and info/warn/error output to stdout. This library builds upon the C++ ostream classes and thus uses stream operators for converting objects into a text representation.

The einhard library supports named output streams (which simply means they automatically add the name to the prefix string). We use this feature to define log areas in SMASH that can be configured independently. The einhard::Logger class supports two options: colorization and verbosity. For colorization we stay with the default of auto-detecting a color-terminal. For verbosity we use a Configuration object to set the verbosity of each area independently. This way we have control over the amount of debug output at runtime and without the need to touch the code/recompile.

To output something from your code do the following:

logg[LAreaName].trace(source_location);
logg[LAreaName].debug("particle", p);
logg[LAreaName].warn("Something happened.");
std::array< einhard::Logger<>, std::tuple_size< LogArea::AreaTuple >::value > logg
An array that stores all pre-configured Logger objects.
Definition: logging.cc:39
constexpr int p
Proton.

Note that LAreaName needs to be declared within the smash namespace of the respective file in a form of (using PauliBlocking as an example area):

static constexpr int LPauliBlocking = LogArea::PauliBlocking::id;
static constexpr int LPauliBlocking
Definition: action.cc:26

The einhard::Logger class supports two ways of writing to an output stream: Use stream operators or pass the list of objects for output as parameters. Thus

log.debug("particle: ", p);

and

log.debug() << "particle: " << p;

are equivalent (except for a small optimization opportunity in the former variant, that could make it slightly more efficient). You can see, though, that the former variant is more concise and often much easier to type than the stream operators.
