Tracing and Profiling

The Trace builtins provide a Mathics3-oriented trace of what is getting evaluated and where the time is spent in evaluation.

With this, it may be possible for both users and implementers to follow how Mathics3 arrives at its results, or guide how to speed up expression evaluation.

Python CProfile profiling is available via PythonCProfileEvaluation.

• ClearTrace — clear any statistics collected for Built-in functions
• PrintTrace — print statistics collected for Built-in functions
• PythonCProfileEvaluation — profile the internal evaluation of an expression
• TraceBuiltins — evaluate an expression and print statistics on Built-in functions called
• $TraceBuiltins — enable or disable Built-in function evaluation statistics
• TraceEvaluation — trace expression evaluation
• $TraceEvaluation — enable or disable displaying the steps to get the result
