puncover 0.7.0

Analyses C/C++ build output for code size, static variables, and stack usage.

puncover

Analyzes C/C++ binaries for code size, static variables and stack usages. It creates a report with disassembler and call-stack analysis per directory, file, or function.

Installation and Usage

Install with pip:

pip install puncover

Run it by passing the binary to analyze:

puncover project.elf
...
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

Open the link in your browser to view the analysis.

You can also use uvx to run the script without installing globally:

uvx puncover project.elf

Running Tests Locally

Setup

To run the tests locally, you need to install the development dependencies. This project uses uv to manage the python environment.

uv venv && source .venv/bin/activate
uv sync

Running Tests

Then you can run the tests with tox (note that this will fail if any of the supported python versions aren't found, see tox.ini):

tox

or, to target only the current python on $PATH:

tox -e py

Publishing Release

Release Script

See release.sh for a script that automates the above steps. Requires uv to be installed. This example will work with the PyPi tokens (now required):

PUNCOVER_VERSION=0.3.5 PYPI_TOKEN=<pypi token> ./release.sh

Manual Steps

Only for reference, the release script should take care of all of this.

Click to expand

1. Update the version in puncover/__version__.py.

2. Commit the version update:

   git add . && git commit -m "Bump version to x.y.z"
   

3. Create an annotated tag:

   git tag -a {-m=,}x.y.z
   

4. Push the commit and tag:

   git push && git push --tags
   

5. Either wait for the GitHub Action to complete and download the release artifact for uploading: https://github.com/HBehrens/puncover/actions OR Build the package locally: python setup.py sdist bdist_wheel

6. Upload the package to PyPI:

   twine upload dist/*
   

7. Create GitHub releases:

   • gh release create --generate-notes x.y.z
   • attach the artifacts to the release too: gh release upload x.y.z dist/*
