Hard pin your installed dependencies

version_lister

Hard pin your dependencies in requirements.txt

This is a simple python program or rather script to update requirements.txt depending upon its state:

1. Check the dependencies(packages) currently installed in the environment.
2. (Req.file Present):For each value of packages present in environment, update those which were listed already in requirements.txt dependency version.
3. (Req.file absent): For all the values of packages in the environment, list them in requirements.txt as it is, with dependencies locked.(You may have to manually remove un-necessary values.) Note : Hence as a necessity, it requires that project dependencies are already installed with working versions.

Aim:

• helping python package authors/owners to hard pin their dependencies with the working version installed in their requirements.txt file before making it public.

• It is not a complete solution for dependency management in building python projects, nor does it in anyway attempts to become so.

Getting Started

• Install:

  • Activate venv/virtualenv, install through pip:
  • pip install version_lister

• Run:

  • add-version in the top level working dir where requirements.txt is present.
• recommended usage :
  • Before running add-version make sure :
    • All required project dependencies are installed.
    • All dependencies are mentioned in the requirements.txt file in any way with or without any semantic versioning.
    • Failure of first results in requirements.txt updated with un-necessary environment packages and no actual required dependency mentioned.
    • Failure of second results in noisy requirements file where other system packages are mentioned alongside actual dependencies.
