query/set the debug level for the current script environment.
level - an integer specifying the current debug level. Debug levels can be OR'd together.
The following debug levels can be combined with the OR operator i.e. 1 | 24:
Level Description 1 display all hard errors as runtime warnings. 2 display all soft errors as runtime warnings. These are the same errors that are caught programatically using &checkError 4 display a runtime warning for the first time use of non-declared variables. 8 trace all function calls (collects profiler statistics) 24 trace function calls only for the purpose of collecting profiler statistics
34 "throw" all errors flagged for use with &checkError 64 trace all predicate decisions (follow program logic) 128 trace propagation of tainted values
If no argument is specified then the current debug level is returned with no changes.
the current debug level
# query and print the current debug level $level = debug(); println("The current debug level is $level"); # turn off all debug warnings debug(0); # enable all debug warnings debug(7); # enable debug options 1 and 4 debug(1 | 4); # turn on debug option 4 (without affecting other options) debug(debug() | 4); # turn off debug option 4 (without affecting other options) debug(debug() & not(4));
The current debug level is 1
