Utility for bumping dependency versions specified in pyproject.toml files

Overview

BumpDeps is a utility for bumping dependency versions specified in pyproject.toml files. It attempts to adhere to specifications outlined in PEP 440 and PEP 508.

BumpDeps can be used as part of a release process or CI workflow to ensure pinned dependencies do not become outdated.

Background

Typically, dependency versions should not have upper-bound pinning because this is a deployment activity. Pinning dependencies moves the implicit security contract from the user to the maintainer. Instead, automated CI testing should run regularly against the latest versions of dependencies with any issues resolved quickly. Upper-bound pinning, if required, should be temporary and tied to an issue or task.

So why does this tool exist? There may be cases where pinning is still done. Whether this is for valid reasons or not, the dependencies in these cases can quickly become outdated. This tool is intended to simplify the process of updating those dependencies.

Usage

For the most basic usage, run bumpdeps in the root of a project. This will bump the base dependencies found in pyproject.toml.

$ bumpdeps

To bump optional dependencies, simplify provide the name of the extra.

$ bumpdeps some_extra some_cooler_extra

To bump all dependencies, use --all or -a

$ bumpdeps --all

For more granular options, see below.

Customizing

BumpDeps behavior can be customized though the use of in-line comments.

If # bumpdeps: ignore is found after a dependency, BumpDeps will skip updates for that dependency.

If # bumpdeps: ignore-until=YYYY-MM-DD is found after a dependency, BumpDeps will skip updates for that dependency until the date provided.

CLI Arguments

usage: bumpdeps [-h] [-a] [-b] [-i REGEX] [-e REGEX] [-f FILE] [–dry-run] [–pkg-index URL] [-d] [EXTRAS …]

-a

–all

Update dependencies for base and all extras

-b

–base

Update base dependencies.

This is the default when no extras are provided. Typically used in combination with specific extras.

-i REGEX

–include REGEX

Regular expression filter. Only dependencies matching the filter will be updated.

-e REGEX

–exclude REGEX

Regular expression filter. Dependencies matching the filter will be skipped.

-f FILE

–file FILE

Path to TOML file. Defaults to pyproject.toml in the current directory.

This file is expected to compatible with the pyproject.toml format.

–dry-run

Show what changes would be made without making any changes.

–pkg-index DIR

URL of package index. Defaults to https://pypi.org.

If using a custom URL, it must have an API compatible with PyPI.

-d

–debug

Show debug output

-h

–help

Show help message and exit
