PyMC Workflow Analyzer

Analyze what how people are using PyMC by parsing folks code. See https://discourse.pymc.io/t/extended-event-gathering-pymc-usage-information/13064 for the higher level discussion

---

The PyMC Workflow Analyzer is a tool designed to statically analyze Python scripts or Jupyter notebooks to identify PyMC workflows. It can process Python files, Python code as a string, or Jupyter notebooks from a local system or a URL.

Features

• Analyze Python scripts or Jupyter notebooks containing PyMC workflows.
• Support for local files, Python code as strings, or files from URLs.
• Detailed reporting of the analysis.

Requirements

• Python 3.6 or higher
• Requests library (pip install requests)
• Nbformat library (pip install nbformat)

Usage

This script can analyze Python scripts or Jupyter notebooks to extract information about PyMC usage. It supports input directly from a file, a string of Python code, or a URL pointing to a Jupyter notebook or a raw Python script.

Command-Line Usage

1. Clone the repository to your local machine.
2. Navigate to the directory containing the script.
3. Run the script using Python and provide the necessary arguments.

Command Line Options

• --file: Path to the local Python script or Jupyter notebook to analyze (Optional).
• --url: URL pointing to a Python script or Jupyter notebook. Ensure this is the URL of the raw file.
• --code: A string of Python code to analyze.
• --output: Specify the path where the output report should be saved. If not provided, the report will be stored to report.txt

Examples

Analyze a local Python file:

python main.py sample_script.py

Analyze a local Jupyter Notebook file:

python main.py sample_script.py

Analyze a local file and save the report to a specified path:

python main.py sample_script.ipynb --output /path/to/save/report.txt

Optional --file argument:

python main.py --file sample_script.ipynb

Analyze code from a direct URL Jupyter Notebook:

python main.py --url https://github.com/bwengals/hsgp/blob/main/cherry_blossoms_hsgp.ipynb

Analyze code from a direct URL containing Python code:

python main.py --url https://github.com/pymc-devs/pymc/blob/main/pymc/sampling/mcmc.py

Analyze a string of code and print the report to the console:

python main.py --code "import pymc as pm; model = pm.Model()"

Output

The script generates a report that includes details about the PyMC functions used, their arguments, and other relevant information extracted from the static analysis of the code.

If the --output option is provided, the report will be saved to the specified path. Otherwise, it will be printed to the console and saved to report.txt.

Python Script Usage

You can also import the static_analyzer function in your Python scripts:

from pymc_workflow_analyzer import static_analyzer

# For local file analysis
report = static_analyzer("sample_script.py") #defaults source_type="file"

# For URL analysis
report = static_analyzer("https://raw.githubusercontent.com/user/repository/branch/file.ipynb", source_type="url")

# For analyzing code as a string
code = """
import pymc as pm
model = pm.Model()
"""
report = static_analyzer(code, source_type="code")

# Process the `report` as needed
