Tool for managing Git repositories in a Fossil monorepo

Fitrepo - Fossil Import Tool

Fitrepo is a command-line tool for managing Git repositories inside a Fossil repository.

Usage

Initializing a New Repository

pip install fitrepo
uv tool run fitrepo --help

How to Use

Run the script from the directory where you want the Fossil repository (monorepo.fossil) and configuration file (fitrepo.json) to reside.

Commands

1. Initialize the Fossil Repository

   uv tool run fitrepo init
   

   • Creates monorepo.fossil if it doesn’t exist.
   • Creates an empty fitrepo.json configuration file if it doesn’t exist.
   • Supports: --help, --version, --verbose, --quiet, --config FILE, --force, --dry-run

2. Import a Git Repository

   uv tool run fitrepo import <git-repo-url> <subdir-name>
   

   • Example: uv tool run fitrepo import https://github.com/user/repo.git hotbox
   • Clones the Git repository, moves its files into the hotbox subdirectory, prefixes its branches (e.g., hotbox/master), and imports it into the Fossil repository.
   • Stores configuration details in fitrepo.json.
   • Supports: --help, --version, --verbose, --quiet, --config FILE, --no-fetch, --force, --dry-run

3. Update an Existing Git Repository

   uv tool run fitrepo update <subdir-name>
   

   • Example: uv tool run fitrepo update hotbox
   • Pulls the latest changes from the Git repository associated with hotbox, reapplies the filters, and incrementally updates the Fossil repository.
   • Supports: --help, --version, --verbose, --quiet, --config FILE, --no-fetch, --no-push, --force, --dry-run

Command-line Options

The tool supports several global options that can be used with any command:

• --help: Show help message and exit.
• --version: Show the version of the tool and exit.
• --verbose: Enable verbose output.
• --quiet: Suppress non-error messages.
• --config FILE: Specify a custom configuration file.
• --no-fetch: Do not fetch the latest changes from the remote repository.
• --no-push: Do not push changes to the remote repository.
• --force: Force the operation to proceed even if there are warnings or errors.
• --dry-run: Show what would be done without making any changes.

Configuration File (fitrepo.json)

The tool maintains a fitrepo.json file to track imported repositories. Example content after importing a repository:

{
    "hotbox": {
        "git_repo_url": "https://github.com/user/repo.git",
        "git_clone_path": ".git_clones/hotbox",
        "git_marks_file": ".marks/hotbox_git.marks",
        "fossil_marks_file": ".marks/hotbox_fossil.marks"
    }
}

Features

• Subdirectory Organization: Each Git repository’s files are placed in a unique subdirectory within the Fossil repository.
• Branch Prefixing: Branches are renamed with the subdirectory name as a prefix (e.g., master becomes hotbox/master).
• Incremental Updates: Uses marks files to ensure only new changes are imported during updates.
• Error Handling: Provides informative error messages for common issues (e.g., duplicate subdirectory names, command failures).
• User Feedback: Logs progress and errors to the console.

Requirements

• Python 3.12+
• Git
• git-filter-repo (automatically installed as a dependency)
• Fossil (installed and accessible from the command line)

Notes

• Run the tool in the directory where you want monorepo.fossil to reside.
• The tool assumes .git_clones/ and .marks/ directories are subdirectories of the current working directory.
• Only branches are prefixed; tags retain their original names. To prefix tags, modify the refname_rewriter string in the code.

This implementation fulfills your intention to create a CLI tool that seamlessly manages multiple Git repositories within a single Fossil repository, with isolated subdirectories and prefixed branches.
