Ftrace - A recursive function call tracer for python. Description ----------- Ftrace is designed to make it easy to debug the behavior of recursive functions by printing a function and the parameters it's called with at each invocation. Use --- To use ftrace, import the ftrace function: from ftrace import ftrace Then, for any function you want to trace add @ftrace above the definiton: @ftrace def your_function: ... Behavior -------- When you run the trace, call-depths and ASCII art are printed along with functions and their parameters. For example, running examples.one(5): >>> import examples >>> examples.one(5) 0 one( (5,) {} ) 1 | two( (4,) {} ) 2 | | one( (3,) {} ) 3 | | | two( (2,) {} ) 4 | | | | one( (1,) {} ) 5 | | | | | two( (0,) {} ) 5 | | | | | two( (0,) {} ) returns: 0 4 | | | | one( (1,) {} ) returns: 1 3 | | | two( (2,) {} ) returns: 2 2 | | one( (3,) {} ) returns: 3 1 | two( (4,) {} ) returns: 4 0 one( (5,) {} ) returns: 5 5 >>> Printing the call depth or the ASCII art can be disabled by toggling ftrace.PRINT_CALLDEPTH_NUM and ftrace.PRINT_ASCII_ART, respectively.
Ftrace doesn't decrease the call depth as an exception bubbles up the call stack.
