xet

xet is a powerful command-line tool for easily managing and updating values across multiple files using a single configuration file (.xet). Whether you need to update versions, secrets, or any arbitrary values in your codebase or configuration files, xet provides a flexible, scriptable, and reproducible workflow.

Key Features

• Batch Value Management: Modify values in many files (supports path name expansion) simultaneously with simple commands.
• Multiple Targeting Modes: Identify values to change by tag, line/column, or regex — works with any text file.
• Presets: Define named presets and instantly switch between configurations for different environments (dev, prod, staging, etc.).
• Local & Global Modes: Use configuration locally in your project, or globally across your system.
• History & Undo/Redo: Mistake? xet tracks changes and supports undo/redo for safe editing.
• SSH Support: Update files on remote systems using SSH integration (via your OpenSSH config).
• Script-Friendly: Works seamlessly in CI/CD pipelines or as part of your automation scripts.

Typical Use Cases

• Bumping version numbers or API keys in many files at once
• Managing configuration across multiple environments
• Keeping secrets or tokens in sync
• Automated updates in build and deploy pipelines

Quick Start

Install with pipx or pip:

pipx install xet
# or
pip install xet

Documentation

Configuration

Initialize Configuration

xet init

• Options:
  • -g, --global: Global Mode. Creates a .xet file in the XDG_CONFIG_HOME folder instead of locally.

Creates an empty .xet if it does not already exist.

Any xet command will use the .xet file in the immediate directory, if there is no local .xet the global .xet file will be used instead. You can force the usage of the global .xet using the -g, --global flag.

Open .xet in editor

xet edit

• Options:
  • -g, --global: Edit the global .xet instead of the local one.

Opens .xet in your standard editor or nano.

Clarify .xet directory
