Tracing your code in MPS
This is one recent feature that perhaps deserves some more popularization – jetbrains.mps.baselanguage.logging has been enhanced with two logging statements, which replace the now deprecated logging statements like error, warn, info and others:
- message outputs a logging message into the MPS Messages view and so provides a very convenient instant way to trace your code. If multiple projects are open in MPS, an optional project parameter can be used to target the Messages view of a particular project.
- log forwards a logging messages to the log4j library using the configuration in $MPS_HOME/bin/log.xml and so it will by default appear in the system log.
Both statements need the severity specified and an optional exception parameter can be also provided.
