pymwp: MWP analysis in Python







pymwp is a tool for automatically performing static analysis on programs written in C.
It is inspired by "A Flow Calculus of mwp-Bounds for Complexity Analysis".
It analyzes resource usage and determines if a program's variables growth rates are no more than polynomially related to their inputs sizes.
Try our online demo to see it action.
For more details on usage and behavior, see pymwp documentation, particularly supported C language features.

Documentation and Demo
Refer to statycc.github.io/pymwp for a documentation, an online demo, and a presentation of examples.

Installation
Install the latest release from PyPI
pip install pymwp

How to Use
To analyze a C file, run:
pymwp path/to_some_file.c

For all available options and help, run:
pymwp --help

You can also use pymwp by importing it in a Python script:
from pymwp import Polynomial
from pymwp.matrix import identity_matrix, show

matrix = identity_matrix(3)
matrix[0][1] = Polynomial('m')
matrix[1][0] = Polynomial('w')
matrix[2][1] = Polynomial('p')

show(matrix)

See modules documentation for available methods.
Running from source
If you want to use the latest stable version (possibly ahead of
latest release), use the version from source following these steps.


Clone the repository
git clone https://github.com/statycc/pymwp.git



Set up Python environment (use venv)
install required packages
python -m pip install -r requirements.txt

Note: for development purposes install dev dependencies instead:
python -m pip install -r requirements-dev.txt



Run the analysis
From project root run:
python -m pymwp path/to_some_file.c

for example:
python -m pymwp c_files/basics/if.c

for all available options and help, run:
python -m pymwp
