# pip‑fund

`pip‑fund` is a small command‑line tool that scans your Python
environment (or a list of package names) and reports any funding or
sponsorship links it can find.  It is inspired by Node.js’s
`npm fund` command and uses Python’s packaging metadata to discover
funding information.  The goal is to make it easy for developers to
discover how to support the open‑source libraries they depend on.

## Features

* **Normalises labels and URLs:** Funding links are detected by
  examining `Project‑URL` metadata and matching normalised labels
  against a set of known aliases such as `funding`, `sponsor`,
  `donate` and `donation`.  Labels containing the words `fund` or
  `sponsor` are also matched.  Query strings and fragments are
  stripped from URLs before grouping, so links that differ only by
  tracking parameters are treated as the same.
* **Groups duplicate links:** When multiple packages share the same
  funding URL, the tool groups them into a single entry and lists
  all associated package names.
* **Multiple output formats:** Choose human‑readable text (default),
  JSON (`--json`) or Markdown (`--markdown`).
* **Remote lookups:** Use the `--remote` flag to query the PyPI JSON
  API for funding links of packages that are not installed locally.
* **Optional GitHub sponsor support:** When installed with the
  `github` extra (`pip install pip‑fund[github]`), the tool can
  attempt to fetch sponsor links from a repository’s
  `.github/FUNDING.yml` file on GitHub if no funding metadata is
  present.  This requires a GitHub access token.

## Installation

### Basic usage

```bash
pip install pip-fund

# Scan all installed packages for funding information
pip-fund

# Check specific packages (installed or not) and query PyPI if needed
pip-fund --remote requests flask

# Output Markdown instead of plain text
pip-fund --markdown
```

### Enabling GitHub sponsor integration

To enable GitHub sponsor discovery, install the `github` extra and
provide a GitHub personal access token via the `GITHUB_TOKEN` environment
variable.  Without a token the GitHub API will operate with very
limited rate limits.

```bash
pip install pip-fund[github]

export GITHUB_TOKEN=ghp_yourtokenhere
pip-fund --github flask
```

## Usage

Running `pip-fund` without arguments scans all installed
distributions in the current Python environment.  For each unique
funding link found, it prints the label, the URL and the names of
packages that declare it.  If no funding information is discovered,
the tool explains why this might be the case.

Use the `--json` or `--markdown` flags to produce machine‑readable
output.  Combine `--remote` with package names to query funding
information for packages that aren’t installed.

## Project structure

This project follows the modern Python packaging guidelines:

* A `pyproject.toml` file declares the build system (`setuptools`) and
  metadata such as the project name, version and console script
  entry point.  The `[project.scripts]` table instructs the build
  backend to generate a `pip-fund` command that invokes the
  `main()` function in `pip_fund/fund.py`【917575989859582†L503-L507】.
* Source code lives in the `src/pip_fund/` package.  The main module
  `fund.py` implements the logic of detecting funding links.
* Optional dependencies for GitHub sponsor support are defined under
  `[project.optional-dependencies]` in `pyproject.toml`.  Installing
  with `pip install pip-fund[github]` adds the `PyGithub` and
  `PyYAML` libraries.

## Contributing

Contributions are welcome!  Feature requests, bug reports and pull
requests are greatly appreciated.  Areas of interest include:

* Improving detection of funding links in package metadata
* Supporting additional donation platforms
* Enhancing the GitHub sponsor integration
* Adding interactive prompts or browser integration to open funding
  pages directly from the CLI
