📝 Walkthrough

## Walkthrough The pull request introduces several modifications across multiple files, primarily enhancing functionality related to node management and clipboard operations. In `node.ts`, new imports and improved action creators are implemented, including the integration of the `toggleSelection` function within the `deleteNodes` action creator. The `injectNode` function is updated to better handle node connections, and the `nodeAdded` function now disables automatic batching during dispatches to support Redux undo functionality. In `ClipboardUtils.ts`, the `writeText` function is redefined to utilize the `navigator.clipboard.writeText` method when available, falling back to a textarea-based approach otherwise. This change is accompanied by the introduction of a new interface to standardize clipboard writing functions. The `SelectionContextProvider.tsx` file sees enhancements in clipboard management and user action handling, including the addition of clipboard permission checks and improved node positioning logic when pasting. The `InputWithIcon.tsx` component modifies the clear button's event handling to maintain focus after clearing input. Lastly, `BindKeyboardShortcuts.tsx` refines keyboard shortcut event handling to prevent copy and cut actions when interacting with input fields, streamlining the overall control flow. ## Sequence Diagram(s) ```mermaid sequenceDiagram participant User participant ClipboardUtils participant SelectionContextProvider participant NodeActions User->>ClipboardUtils: writeText("example text") alt Clipboard API available ClipboardUtils->>User: Promise resolved with "example text" else Fallback ClipboardUtils->>User: Promise resolved with "example text" (via textarea) end User->>SelectionContextProvider: paste() SelectionContextProvider->>ClipboardUtils: read clipboard text SelectionContextProvider->>NodeActions: parseInsertNodes(clipboard text) NodeActions->>NodeActions: calculate node positions NodeActions->>User: Nodes pasted successfully ```

🪧 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` 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://docs.coderabbit.ai) for detailed information on how to use CodeRabbit. - Join our [Discord Community](http://discord.gg/coderabbit) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
