poetry-plugin-pycopy 1.0.6

Copy fields from pyproject.toml to source directory

poetry-plugin-pycopy

This plugin adds command pycopy to Poetry which will copy information from pyproject.toml to source directory.

The goal is to have pyproject.toml as a single source of truth for app version, name, description etc. and to have these values available during a program runtime.

Use case

FastAPI app in which you want to show application name or version in API docs.

Installation

From Pypi:

$ poetry self add poetry-plugin-pycopy

Usage

$ poetry pycopy

Plugin configuration in pyproject.toml

[tool.poetry-plugin-pycopy]
keys = ["name", "version", "description"]
dest_dir = "<some_package_name>"
dest_file = "__init__.py"

• keys list tells which fields should by copied from [tool.poetry]
• dest_dir is package/module root
• dest_file is the name of an output file

Plugin also runs with $poetry version command automatically. So when you use version bump, e.g.: $poetry version patch the plugin will copy the new version value into the output file.

Output file example

The dest_file is set to __init__.py. Thus the plugin will create or replace that file with current values for a given keys. For example:

pyproject_toml = {
    "name": "test-venv-1",
    "version": "0.1.0",
    "description": "dsa",
}
