poncho_package_analyze - command-line utility for analyzing Python script for library and interpreter dependencies
poncho_package_analyze [options] <python-script ...> <json-output-file>
poncho_package_analyze is a simple command line utility for analyzing Python scripts for the necessary external dependencies. It generates an output file that can be used with python_package_create to build a self-contained Conda environment for the Python application.
The python-script ... argument is the path(s) to the Python script(s) to be analyzed. The json-output-file argument is the path to the output JSON file that will be generated by the command. Specifying - for either will use stdin/stdout instead of a file.

Only include imports at the top level of the script.
Only include imports in the given function.
Specify that the module imported as <import> in the code is provided by the pip/conda package <name>.
Also include the pip/conda package <pkg>, even if it does not appear in the sources. May be useful for scripts that execute other (possibly non-Python) components that must also be included.
On success, returns zero. On failure, returns non-zero.
An example Python script example.py contains the following code:
import os import sys import pickle import antigravity import matplotlib if __name__ == "__main__": print("example")
To analyze the example.py script for its dependencies and generate the output JSON dependencies file dependencies.json, run the following command:
$ poncho_package_analyze example.py dependencies.json
Once the command completes, the dependencies.json file within the current working directory will contain a Conda environment specification (suitable to use with conda env create).
Note that system-level modules are considered part of the Python package installed into the Conda environment. Additionally, imports not managed by Pip or Conda are not allowed. This includes other modules within the CWD or in user-written packages.
