Usage

In your pyproject.toml make the following changes:

• Append hatch-requirements-txt to build-system.requires.
• Append "dependencies" to project.dynamic.
• Add the following table:

.. code-block:: toml

[tool.hatch.metadata.hooks.requirements_txt]
files = ["requirements.txt"]

The resulting pyproject.toml should look something like:

.. code-block:: toml

[build-system]
requires = ["hatchling", "hatch-requirements-txt"]
build-backend = "hatchling.build"

[project]
name = "my-project"
version = "1.0.0"
dynamic = ["dependencies"]

[tool.hatch.metadata.hooks.requirements_txt]
files = ["requirements.txt"]

You can also define groups of optional dependencies <https://hatch.pypa.io/latest/config/dependency/#features>_ (also known as "features") by appending optional-dependencies to project.dynamic and adding a table like:

.. code-block:: toml

[tool.hatch.metadata.hooks.requirements_txt.optional-dependencies]
crypto = ["requirements-crypto.txt"]
fastjson = ["requirements-fastjson.txt"]
cli = ["requirements-cli.txt"]

Requirements file format

hatch-requirements-txt only supports a subset of the requirements.txt format_ supported by pip. The following are supported:

• requirement specifiers, per PEP 508_
• Comments, prefixed with a #.
• --<option> options, both on their own line and after a requirement specifier. Note however that the options themselves are ignored.

The following are unsupported:

• Editable install commands with the -e option,
• References to other requirements or constraints files with the -r or -c options.
• References to paths on the local filesystem, or URLs.

TL;DR For best compatibility, ensure all lines in your requirements.txt files are valid PEP 508 requirements, or comments starting with a #.
