Python model of the Fortran package manager

This project provides a pydantic model of the fpm package manifest format used in the Fortran package manager.

Installation

Install this project with pip

pip install git+https://github.com/fortran-lang/fpm-metadata

Usage

You can read a package manifest with your TOML library of choice and construct a manifest object from it which allows to access all package entries directly in Python

>>> from fpm.metadata import Manifest
>>> from tomlkit import loads
>>> with open("fpm.toml") as fh:
...     package = Manifest(**loads(fh.read()))
...
>>> package.name
'fpm'
>>> package.version
'0.2.0'

Alternatively, you can use the load_manifest function to read a package manifest

>>> from pathlib import Path
>>> from fpm.metadata import load_manifest
>>> package = load_manifest(Path("fpm.toml"))
>>> package.name
'fpm'
>>> package.version
'0.2.0'

Finally, you can dump a package manifest to a TOML string using the dump_manifest function

>>> from pathlib import Path
>>> from fpm.metadata import dump_manifest, load_manifest
>>> package = load_manifest(Path("fpm.toml"))
>>> print(dump_manifest(package))
name = "fpm"
version = "0.2.0"
...
