The cosmos generator linked a consumer to its provider only through an '<role>' in group_names reference or an explicit provides: name. A hard dependency has neither -- pinning the provider on unconditionally is exactly what removes the Jinja reference the generator was reading -- so web-svc-asset's bond to web-svc-file vanished from the diagram the moment it became binding. Match a service key against the provider's own primary key from the registry, in both directions. Services the role turns off drew a solid 1:1 edge, claiming a mandatory relationship for something that carries nothing at deploy time. They now render as a red 0..0 edge; edge merging gained a real precedence so a provider consumed through two keys stays live when only one is off. Named colour, not hex: a '#' opens an entity code in the mermaid lexer and turns the whole diagram into a parse error on GitHub. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# Python Development Utilities
|
||
|
||
## Description
|
||
|
||
This Ansible role sets up a Python development environment on Arch Linux. It includes Python itself, the `pip` package manager, and builds on the general developer persona to support scripting, application development, data science, and more.
|
||
|
||
Learn more at the [Python Official Site](https://www.python.org/), the [Arch Wiki - Python](https://wiki.archlinux.org/title/Python), and [Wikipedia – Python](https://en.wikipedia.org/wiki/Python_(programming_language)).
|
||
|
||
## Overview
|
||
|
||
This role provides the essential tooling for Python developers, enabling immediate use of `python` and `pip` from the command line. It supports both general-purpose scripting and advanced software engineering workflows.
|
||
|
||
## Cosmos
|
||
|
||
The diagram places Python Development Utilities in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).
|
||
|
||
```mermaid
|
||
flowchart LR
|
||
subgraph deps [Dependencies]
|
||
dep_dev_core["dev-core 💻 ⚙️"]
|
||
end
|
||
subgraph role [dev-python 💻]
|
||
svc_python["python"]
|
||
end
|
||
dep_dev_core -- "1:1" --> svc_python
|
||
```
|
||
|
||
Solid `1:1` edges are fixed relationships; dashed `0..1` edges are conditional (enabled only in matching deployments); red `0..0` edges are turned off in this role. Node markers show the role's deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in `meta/main.yml`.
|
||
|
||
## Purpose
|
||
|
||
To simplify and standardize the provisioning of Python-ready environments for developers, students, data scientists, and automation engineers.
|
||
|
||
## Features
|
||
|
||
- **Installs Python and Pip:** Ensures the interpreter and package manager are available.
|
||
- **Prefers Python 3.11+:** Installs Python 3.11+ where available and makes it the default via `/usr/local/bin/python3` and `/usr/local/bin/pip3`.
|
||
- **Persona Integration:** Extends `dev-core` with Python-specific tools.
|
||
- **Foundation for Further Stacks:** Ideal starting point for Flask, Django, scientific computing, and automation.
|
||
|
||
Supported distro families in the installer script:
|
||
|
||
- Arch Linux
|
||
- Debian
|
||
- Ubuntu
|
||
- Fedora
|
||
- CentOS / RHEL
|
||
|
||
## Customization
|
||
|
||
Easily extend this role with:
|
||
|
||
- Python virtualenv tools (`python-virtualenv`, `pyenv`)
|
||
- Popular libraries (`numpy`, `requests`, `flask`)
|
||
- Framework-specific roles (e.g., `dev-python-django`)
