Yarn JS package manager lockfile parser
Project description
PYarn
If, for some weird reason, you need to parse a Yarn's yarn.lock file using
Python, you are in the right place!
PYarn is currently in an early developmente stage. It will create a dict from a yarn.lock file, given the yarn.lock file is correct as per its implementation. At this moment, there is no guarantees that PYarn will behave well (e.g., raise an error) in case a malformed Yarn lockfile is passed to PYarn.
PYarn only supports Yarn v1 lockfiles. Parsing Yarn v2 lockfiles should be trivial since they are yaml files.
Development
make devel
make check
Usage
The following prints all the content in the yarn.lock file:
from pyarn import lockfile
my_lockfile = lockfile.Lockfile.from_file(FILE_NAME)
print(my_lockfile.data)
# or
my_lockfile.to_json()
my_lockfile.data is a dict where the top level keys are the top level entries
(i.e., the package names) for the yarn.lock file entries.
Releasing
Before releasing a new version to PyPI, don't forget to bump the version number in setup.cfg.
Make sure to git tag the release commit with the corresponding version and create
a Github release explaining what is new.
Afterwards, releasing to PyPI is quite simple:
make build
twine check dist/*
twine upload dist/*
