Walkthrough

The trap built-in command has undergone a comprehensive update, enhancing its documentation, refactoring its command structure, and bolstering its error handling and testing. Parsing of command line arguments and signal numbers has been improved, and performance optimizations have been applied. The changes align terminology with POSIX standards and extend test coverage for the trap functionality in a shell environment.

Poem

Amidst the code where logic weaves, The trap ensnares with grace and ease. Bugs flee from tests, their fate is sealed, With every patch, the shell is healed. 🐇✨

Tips ### Chat with CodeRabbit Bot (`@coderabbitai`) - You can directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit .` - `Generate unit-tests for this file.` - You can tag CodeRabbit on specific lines of code or entire files in the PR by tagging `@coderabbitai` in a comment. Examples: - `@coderabbitai generate unit tests for this file.` - `@coderabbitai modularize this function.` - You can tag `@coderabbitai` in a PR comment and ask questions about the PR and the codebase. Examples: - `@coderabbitai generate interesting stats about this repository from git and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@coderabbitai read src/utils.ts and generate unit tests.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid.` - `@coderabbitai read the files in the src/scheduler package and generate README in the markdown format.` 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. ### CodeRabbit Commands (invoked as PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger a review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai help` to get help. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### CodeRabbit Configration File (`.coderabbit.yaml`) - You can programmatically configure CodeRabbit by adding a `.coderabbit.yaml` file to the root of your repository. - The JSON schema for the configuration file is available [here](https://coderabbit.ai/integrations/coderabbit-overrides.v2.json). - 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/coderabbit-overrides.v2.json` ### CodeRabbit Discord Community Join our [Discord Community](https://discord.com/invite/GsXnASn26c) to get help, request features, and share feedback.
