📝 Walkthrough
📝 Walkthrough ## Walkthrough The changes enhance the configuration flow handler by clarifying the management of unique IDs. A unique ID, required for certain integrations, prevents duplicate setups and allows users to ignore unnecessary discovery notifications. The documentation now includes an alternative approach for cases where a unique ID is not available, detailing how to handle discovery while still allowing user interaction. The flow will abort if a duplicate unique ID is detected or if an existing configuration entry is present. ## Changes | Files | Change Summary | |--------------------------------------------|------------------------------------------------------------------------------------------------| | docs/config_entries_config_flow_handler.md | Enhanced documentation on unique ID management, including requirements and alternative handling methods. | ## Sequence Diagram(s) ```mermaid sequenceDiagram participant User participant ConfigFlowHandler participant ConfigEntryManager User->>ConfigFlowHandler: Start configuration flow ConfigFlowHandler->>ConfigFlowHandler: Assign unique ID alt Another flow in progress ConfigFlowHandler->>User: Abort flow (ID conflict) else Existing entry found ConfigFlowHandler->>User: Abort flow (entry exists) else Proceed ConfigFlowHandler->>ConfigEntryManager: Create new configuration entry ConfigEntryManager-->>ConfigFlowHandler: Entry created ConfigFlowHandler->>User: Flow completed successfully end ```

🪧 Tips ### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit , 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. ### CodeRabbit Commands (Invoked using PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. ### Other keywords and placeholders - Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. - Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description. - Add `@coderabbitai` or `@coderabbitai title` anywhere in the PR title to generate the title automatically. ### CodeRabbit Configuration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - Please see the [configuration documentation](https://docs.coderabbit.ai/guides/configure-coderabbit) for more information. - If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: `# yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json` ### Documentation and Community - Visit our [Documentation](https://coderabbit.ai/docs) for detailed information on how to use CodeRabbit. - Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
