Is tomlkit compatible with older versions of Python?

The tomlkit library used by this skill supports Python 3.8 and above, making it widely applicable for modern Python development.

Does it support cross-platform configuration paths?

Yes, the skill includes integration guidance for the XDG Base Directory specification to ensure configuration files are stored in the correct locations on Linux, macOS, and Windows.

How does this skill prevent configuration file corruption?

It provides established patterns for atomic updates, involving writing to a temporary file before performing a move operation, ensuring the configuration remains intact even during a crash.

Can this skill help with pyproject.toml files?

Yes, it is specifically optimized to handle pyproject.toml and other standard Python configuration files without disrupting existing metadata or formatting styles.

Why use tomlkit instead of the standard tomllib?

While tomllib (introduced in Python 3.11) is excellent for read-only access, tomlkit is required if you need to write or modify TOML files while preserving comments, whitespace, and formatting.

Developer Tools

Manages TOML configuration files in Python with a focus on preserving comments, formatting, and structural integrity during read-write operations.

About

This skill provides a comprehensive framework for handling TOML files within Python environments, primarily leveraging the tomlkit library to ensure that human-authored comments and specific formatting are preserved during automated updates. It bridges the gap between raw data manipulation and configuration management, offering patterns for atomic updates, schema validation, and integration with the XDG Base Directory specification. Whether you are managing pyproject.toml files or building complex application settings, this skill ensures your configuration remains both machine-readable and developer-friendly.

Key Features

Implementation patterns for atomic configuration updates to prevent file corruption.
Automated TOML validation and error handling for robust application settings.
Guidelines for selecting between tomlkit and the Python 3.11+ tomllib standard library.
Support for XDG Base Directory standards for cross-platform configuration storage.
10 GitHub stars
Comment and formatting preservation during read-modify-write cycles using tomlkit.

Use Cases

Automating updates to pyproject.toml manifests without destroying hand-written comments or specific indentation.
Implementing safe, atomic configuration changes for high-uptime Python applications and services.
Building CLI tools that require persistent user configuration stored in standard OS locations.
