Proposed Changes for git-sync

Overview

The discussion revolves around enhancing the command-line interface (CLI) experience for git-sync. The primary focus is on structuring help commands to provide clearer usage instructions for users.

Current Implementation Issues

1. Usage Block Structure
   The current implementation using the standard library flag package only produces a single usage block, making it harder for users to find help for specific subcommands.

2. Error Handling
   All error scenarios return the same usage error, leading to confusion for users.

Proposed Solutions

1. Migration to Cobra Package

   • Transitioning to the Cobra package which offers built-in support for subcommand help.
   • Each subcommand automatically receives its own --help option.
   • Provides a root command that can display usage more cleanly when invoked without parameters, improving usability.

2. Refactor Existing Command Logic

   • Replace the large usageError block with concise messages based on the invoked command.
   • Maintain backward compatibility for existing command behavior while providing enhancements.

Recommendations

• Migrate to Cobra: This approach not only smooths the user experience but also allows for easier maintenance and expansion in the future.

Implementation Details

• The cmd/git-sync/main.go file will contain streamlined entry logic.
• The cmd/git-sync/root.go file will define a new root command that shows help when no arguments are provided.
• All command files (e.g., sync.go, bootstrap.go, etc.) will be consolidated for better organization.

Behavioral Changes

• Successful Exit Codes: Invoking git-sync without any commands should result in a success exit status instead of failure.
• Error Messaging: Improved error messaging will guide users better by showing relevant command options when wrong flags or commands are invoked.

Testing and Maintenance

• All functionalities have been verified to ensure that existing commands operate as expected after the migration.
• Continuous integration checks to keep linting and testing in place to maintain code quality.

Note: All relevant flags and behaviors have been preserved to ensure a seamless transition for users.
