polytropos 3.2.2

A build backend for Odoo modules supporting multiple versions

Polytropos

Polytropos is a Python build backend for Odoo modules that enables writing code once and using it across multiple Odoo releases.

Features

• Multi-release support: Write your module once, target multiple Odoo releases
• Conditional manifests: Configure different manifest values per Odoo release, to let you include or exclude data files per release
• Editable installs: Develop in editable is supported
• PEP 517 compliant: Works with any PEP 517 compatible frontend

Quick Example

Replace your module's __manifest__.py with this pyproject.toml file:

[build-system]
requires = ["polytropos[build]"]
build-backend = "polytropos.build"

[project]
name = "odoo-addon-my-module"
version = "1.0.0"
dependencies = [
    # Specify supported Odoo versions here
    "odoo>=17"
]

# All versions have this data
[[tool.polytropos.manifest]]
depends = ["base"]
data = ["data/views.xml"]

# This section is only for Odoo 18+
[[tool.polytropos.manifest]]
releases = ">=18"
data = ["security/ir.model.access.csv"]

Then, inside the module folder:

# Don't forget the module must be a Python package
touch __init__.py

# Build wheels for different odoo releases
uv build --sdist
uv build --wheel --config-setting odoo_release=17.0
uv build --wheel --config-setting odoo_release=18.0
uv build --wheel --config-setting odoo_release=19.0

# List artifacts
ls -1 dist/
my_module-1.0.0.tar.gz
odoo_addon_my_module-17.0.1.0.0-py3-none-any.whl
odoo_addon_my_module-18.0.1.0.0-py3-none-any.whl
odoo_addon_my_module-19.0.1.0.0-py3-none-any.whl

Single branch, single code, multiple releases! 🤯

Installation

Python will auto-install the build backend when you build a module.

But yes, you can install a small CLI with:

pip install polytropos[cli]

For development, the recommended tool you need is uv. Then:

uvx polytropos[cli] --help-all

Why Polytropos?

Odoo modules traditionally require separate codebases or branches for each release. Polytropos solves this by generating release-specific code at build time, allowing you to maintain a single codebase.

So, it will help you or not depending on your product vision:

What is your product?	What does that mean?	Is Polytropos for you?
Odoo + its release + all addons in that release	Customers that want new features must upgrade to newer Odoo releases.	⛔ No
Addons that should work always the same way	Customers need new features and cannot wait for the upgrade to the next Odoo release; but when they upgrade, they expect the same features they have now	✅ Yes

Examples
