Helpful Hints

Debug Trace and Logging

Ejscript has a debug logging and trace facility that can help when debugging configuration issues or developing your application code that uses Ejscript. You can see each script statement as it is executed and what byte codes the VM is executing. You can vary the level of logging via the --log logfile command line switch for the ejs command. The log command line switch has the format

ejs --log logFile:logLevel

The log level can be from 0 to 9, with 9 being the most verbose level. If compiling your scripts with debug enabled via the --debug switch, a log level setting of 5 will trace each source statement and assembly byte code to the log file.
