hatch-pip-compile

hatch plugin to use pip-compile (or uv) to manage project dependencies and lockfiles.

Usage

The hatch-pip-compile plugin will automatically run pip-compile whenever your environment needs to be updated. Behind the scenes, this plugin creates a lockfile at requirements.txt (non-default lockfiles are located at requirements/requirements-{env_name}.txt). Once the dependencies are resolved the plugin will install the lockfile into your virtual environment and keep it up-to-date.

Installation

Declare hatch-pip-compile as a dependency in your pyproject.toml file under the [tool.hatch.env] table and hatch will automatically install it. You must also have your environment type set to pip-compile (see Configuration).

• pyproject.toml

  [tool.hatch.env]
  requires = [
      "hatch-pip-compile"
  ]
  
  [tool.hatch.envs.default]
  type = "pip-compile"
  

• hatch.toml

  [env]
  requires = [
      "hatch-pip-compile"
  ]
  
  [envs.default]
  type = "pip-compile"
  

Configuration

Set your environment type to pip-compile to use this plugin for the respective environment:

• pyproject.toml

  [tool.hatch.envs.default]
  type = "pip-compile"
  

• hatch.toml

  [envs.default]
  type = "pip-compile"
  

Common Scenarios

• lock-filename - changing the default lockfile path
• pip-compile-constraint - syncing dependency versions across environments
• Upgrading Dependencies - how to upgrade dependencies
• Using Hashes - how to include hashes in your lockfile
• Using uv instead of pip-compile - how to use uv instead of pip-compile

Configuration Options

The plugin gives you options to configure how lockfiles are generated and how they are installed into your environment.

The following example shows how to specify the pip-compile-hashes option on your environment in your pyproject.toml file:

[tool.hatch.envs.default]
type = "pip-compile"
pip-compile-hashes = true

Generating Lockfiles

name	type	description
lock-filename	str	The filename of the ultimate lockfile. default env is requirements.txt, non-default is requirements/requirements-{env_name}.txt
pip-compile-constraint	str	An environment to use as a constraint file, ensuring that all shared dependencies are pinned to the same versions.
pip-compile-hashes	bool	Whether to generate hashes in the lockfile. Defaults to false.
pip-compile-resolver	str	Whether to use pip-compile or uv to resolve dependencies into the project. Defaults to pip-compile
pip-compile-args	list[str]	Additional command-line arguments to pass to pip-compile-resolver
pip-compile-verbose	bool	Set to true to run pip-compile in verbose mode instead of quiet mode, set to false to silence warnings

Installing Lockfiles

name	type	description
pip-compile-installer	str	Whether to use pip, pip-sync, or uv to install dependencies into the project. Defaults to pip
pip-compile-install-args	list[str]	Additional command-line arguments to pass to pip-compile-installer
