poseur - Backport Compiler for Positional-only Parameters

Write positional-only parameters in Python 3.8 flavour, and let poseur worry about back-port issues 🍺

Since PEP 570, Python introduced positional-only parameters syntax in version 3.8. For those who wish to use positional-only parameters in their code, poseur provides an intelligent, yet imperfect, solution of a backport compiler by replacing positional-only parameters syntax with old-fashioned syntax, which guarantees you to always write positional-only parameters in Python 3.8 flavour then compile for compatibility later.

Installation

Warning

poseur is currently under reconstruction. It is highly recommended to directly install from the git repo or the pre-release distributions.

Note

poseur only supports Python versions since 3.4 🐍

For macOS users, poseur is available through Homebrew:

brew tap jarryshaw/tap
brew install poseur
# or simply, a one-liner
brew install jarryshaw/tap/poseur

You can also install from PyPI for any OS:

pip install bpc-poseur

Or install the latest version from the Git repository:

git clone https://github.com/pybpc/poseur.git
cd poseur
pip install -e .
# and to update at any time
git pull

Note

Installation from Homebrew will also automatically install the man page and Bash Completion script for you. If you are installing from PyPI or the Git repository, you can install the completion script manually.
