GitAuto: [FEATURE] Add Command to Set Environment Variable

[gitauto-ai]

Resolves #38

What is the feature

Add a new command to the .NET CLI tool that allows users to set environment variables via the command-line interface. The command accepts two arguments:

1. Variable Value (required): Specifies the environment variable in the format VAR_NAME=value.
2. Target Scope (optional): Specifies where the environment variable should be set (User or Machine). Defaults to User if not provided.

Why we need the feature

This feature simplifies the process of setting environment variables, particularly in CI/CD pipelines and automated scripts. By enabling users to set environment variables directly through the CLI tool, it enhances automation capabilities and reduces the need for manual configuration. Additionally, the ability to specify the target scope provides flexibility, allowing users to choose between setting variables for the current user or system-wide.

How to implement and why

1. Define the Command Structure:

   • Create a new command set-env within the CLI tool.
   • Configure the command to accept the environment variable in the format VAR_NAME=value.
   • Add an optional --target flag to specify the scope (User or Machine).

2. Parse Command-Line Arguments:

   • Implement argument parsing to extract the variable name, value, and target scope.
   • Ensure that the variable argument is required and validate its format.
   • Set the default target scope to User if the --target flag is not provided.

3. Set the Environment Variable:

   • Utilize the .NET Environment.SetEnvironmentVariable method to set the variable.
   • Determine the EnvironmentVariableTarget based on the provided target scope.
   • Handle cases where setting a Machine scope variable requires elevated permissions.

4. Provide User Feedback:

   • After setting the variable, output a confirmation message indicating the variable name, value, and scope.
   • Handle and display error messages for invalid inputs or permission issues.

5. Update Documentation and Help Text:

   • Add usage examples to the CLI tool's help documentation.
   • Ensure that users understand how to use the new set-env command and the implications of setting different scopes.

6. Write Unit Tests:

   • Implement tests to verify that environment variables are set correctly for both User and Machine scopes.
   • Test edge cases, such as invalid variable formats and insufficient permissions.

7. Integrate with Existing Codebase:

   • Place the new command implementation within the appropriate directory (e.g., Src or a specific commands folder).
   • Ensure consistency with the project's coding standards and practices.

This step-by-step implementation ensures that the feature is robust, user-friendly, and seamlessly integrated into the existing CLI tool, providing valuable functionality to users.

About backward compatibility

Introducing the set-env command is an additive change and does not affect existing commands or functionalities of the CLI tool. There are no breaking changes, ensuring that current users and scripts continue to function as before. This enhancement maintains backward compatibility while providing additional capabilities.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
