Simple logic path tracer

OracleTrace

OracleTrace is a simple logic path tracer for Python applications. It visualizes the execution flow of your code, helping you understand function calls and performance bottlenecks.

GitHub: https://github.com/KaykCaputo/oracletrace

Features

• Performance Summary Table: Visualize the most time-consuming functions with a clean table showing totam time, and average time per call.
• Logic Flow Visualization: See a tree structure of function calls.
• Performance Metrics: View execution time and call counts for each function.
• Clean Output: Filters out internal Python calls for better readability.

How It Works

OracleTrace uses Python's built-in sys.setprofile() function to intercept function call events (call, return). It measures the time spent inside each function and records the caller-callee relationships. By tracking the file path of each function, it can filter out calls that are not part of your local project directory, resulting in a clean and relevant report.

Installation

pip install oracletrace

Quick Start

1. Create a Python script. For example, save the following as my_app.py:

   # my_app.py
   import time
   
   def process_data():
       print("  > Processing data...")
       time.sleep(0.1)
       calculate_results()
   
   def calculate_results():
       print("    > Calculating results...")
       time.sleep(0.2)
   
   def main():
       print("Starting application...")
       for i in range(2):
           print(f"\nIteration {i+1}:")
           process_data()
       print("\nApplication finished.")
   
   if __name__ == "__main__":
       main()
   

2. Run oracletrace from your terminal:

   oracletrace your_script.py
   

   Or run it as a module:

   python -m oracletrace.cli your_script.py
   

Example Output

Running the command above will execute your script and then generate a report like this:

Starting application...

Iteration 1:
  > Processing data...
    > Calculating results...

Iteration 2:
  > Processing data...
    > Calculating results...

Application finished.
