goldpy-cli 0.1.2

A small CLI for checking Swissquote gold prices from the terminal.

goldpy

goldpy is a command line tool for people who want a fast answer to a simple question: what is gold trading at right now?

I wanted something small, readable, and honest about the data it shows. The CLI pulls live quote data from Swissquote, validates the response with Pydantic, and prints either terminal-friendly output or structured JSON.

The default behavior uses an aggregate quote strategy. It finds the best bid and best ask across the returned quote sources and profiles, then calculates a mid price from those values. If you want something more specific, you can filter by platform, spread profile, or switch selection mode.

What it does

• Fetches live precious metal quotes from Swissquote
• Defaults to XAU/USD
• Supports other instrument pairs like XAU/EUR
• Prints either readable terminal output or JSON
• Lets you inspect available platforms and spread profiles
• Ships as a normal Python package managed with uv

Installation

For local development:

uv sync --group dev

Once published to PyPI, the intended install will be:

uv tool install goldpy-cli

Usage

Basic quote:

uv run goldpy price

JSON output:

uv run goldpy price --json

Different pair:

uv run goldpy price --pair XAU/EUR

Specific source options:

uv run goldpy price --platform SwissquoteCapitalMarkets --spread-profile prime

List available platforms and spread profiles for a pair:

uv run goldpy price --list-options

Use the tightest single quote instead of the aggregate view:

uv run goldpy price --mode tightest

Development

Run tests:

uv run --group dev pytest

Run coverage:

uv run --group dev coverage run -m pytest
uv run --group dev coverage report -m

The test suite is configured to require 100% coverage.

Documentation

This repository now includes a Sphinx setup that uses Markdown via MyST, so you do not need to write reStructuredText.

Build the docs locally:

uv sync --group dev --group docs
uv run --group docs sphinx-build -b html docs docs/_build/html

The project also includes a .readthedocs.yaml file for publishing on Read the Docs.

Releases

This project publishes from Git tags that match v*, for example v0.1.0.

Typical release flow:

uv version --bump patch
git commit -am "Bump version to $(uv version --short)" -m "Co-authored-by: OpenAI Codex <[e-mail]>"
git tag "v$(uv version --short)"
git push origin main --tags

The GitHub Actions release workflow builds the sdist and wheel, then publishes them to PyPI using trusted publishing via pypa/gh-action-pypi-publish. It also checks that the pushed tag exactly matches the version declared in pyproject.toml.

Versioning

goldpy uses straightforward semantic versioning:

• Patch releases for fixes and small internal improvements
• Minor releases for new CLI options or behavior that stays backward compatible
• Major releases for breaking CLI or output changes
