Configuration Poetry can be configured via the config command (see more about its usage here) or directly in the config.toml file that will be automatically created when you first run that command. This file can typically be found in one of the following directories: macOS: ~/Library/Application Support/pypoetry Windows: %APPDATA%\pypoetry For Unix, we follow the XDG spec and support $XDG_CONFIG_HOME. That means, by default ~/.config/pypoetry. Local configuration Poetry also provides the ability to have settings that are specific to a project by passing the --local option to the config command.

The pyproject.toml file The tool.poetry section of the pyproject.toml file is composed of multiple sections. name The name of the package. Required This should be a valid name as defined by PEP 508. name = "my-package" version The version of the package. Required This should be a valid PEP 440 string. version = "0.1.0" Note If you would like to use semantic versioning for your project, please see here. description A short description of the package. Required

The pyproject.toml file In package mode, the only required fields are name and version (either in the project section or in the tool.poetry section). Other fields are optional. In non-package mode, all fields are optional. Note Run poetry check to print warnings about deprecated fields. The project section The project section of the pyproject.toml file according to the specification of the PyPA. name The name of the package. Required in package mode

Managing environments Poetry makes project environment isolation one of its core features. What this means is that it will always work isolated from your global Python installation. To achieve this, it will first check if it’s currently running inside a virtual environment. If it is, it will use it directly without creating a new one. But if it’s not, it will use one that it has already created or create a brand new one for you.

Community Badge For any projects using Poetry, you may add its official badge somewhere prominent like the README.

Commands You’ve already learned how to use the command-line interface to do some things. This chapter documents all the available commands. To get help from the command-line, simply call poetry to see the complete list of commands, then --help combined with any of those can give you more information. Global options --verbose (-v|vv|vvv): Increase the verbosity of messages: “-v” for normal output, “-vv” for more verbose output and “-vvv” for debug. --help (-h) : Display help information. --quiet (-q) : Do not output any message. --ansi: Force ANSI output. --no-ansi: Disable ANSI output. --version (-V): Display this application version. --no-interaction (-n): Do not ask any interactive question. --no-plugins: Disables plugins. --no-cache: Disables Poetry source caches. --directory=DIRECTORY (-C): The working directory for the Poetry command (defaults to the current working directory). new This command will help you kickstart your new Python project by creating a directory structure suitable for most projects.

Managing dependencies Poetry supports specifying main dependencies in the project.dependencies section of your pyproject.toml according to PEP 621. For legacy reasons and to define additional information that are only used by Poetry the tool.poetry.dependencies sections can be used. See Dependency specification for more information. Dependency groups Poetry provides a way to organize your dependencies by groups. The dependencies declared in project.dependencies respectively tool.poetry.dependencies are part of an implicit main group. Those dependencies are required by your project during runtime.

pre-commit hooks pre-commit is a framework for building and running git hooks. See the official documentation for more information: pre-commit.com This document provides a list of available pre-commit hooks provided by Poetry. Note If you specify the args: for a hook in your .pre-commit-config.yaml, the defaults are overwritten. You must fully specify all arguments for your hook if you make use of args:. Note If the pyproject.toml file is not in the root directory, you can specify args: ["-C", "./subdirectory"]. poetry-check The poetry-check hook calls the poetry check command to make sure the poetry configuration does not get committed in a broken state.
