By default it shows function parameters and function return values

Options:

-F do not trace function parameters
-r trace function return values (default: on)
-R do not trace function return values
-l trace source lines before they are executed (default: on)

-s trace setting of variablesa (default: off)
-S do not trace setting of variables
-g trace getting of variables (default: off)
-G do not trace getting of variables
-o print out object content (default: off)
-O do not print out object content
-t show the current thread id in prefix for each source line (default on)
-T hide the current thread id
-n show the nesting level, how many levels down the call stack (default on)
-N hide the nesting level

can be invoked as an api


class NTraceFromCommandLine

command line parser for ntrace

Methods defined here:
__init__(self, argv)

class NTracer

the tracer object; invoke this class to run a python file with tracing

Methods defined here:
__init__(self, traceOptions=31, follow_objects=False)
object constructor; options are passed as bit mask values via traceOptions parameter, available options:

TO_FUNCTION_ARGUMENTS argument flag: print function arguments TO_FUNCTION_RVALUES argument flag: print function return values TO_SET_VARS argument flag: print modification of variables TO_GET_VARS argument flag: print variable access TO_TRACE_SRC_LINES argument flag: show souce lines before they are executed TO_SHOW_PREFIX_TID show thread id in prefix string of lines traced TO_SHOW_PREFIX_NESTING show call strack nesting in prefix string of lines traced

follow_objects parameter is true if object references are to be printed trace(self, progname, tracingenabled=True) tracer invocation progname - python file to be traced tracingenabled - if tracing is initially on (True by default)

Functions

enabletrace(on)
enable/disable tracing, can be called from the traced program
