Replace OsStr with UnixStr #401

Closed magicant closed 2 months ago

magicant commented 2 months ago

The OsStr type in std behaves differently depending on the target platform. Since yash is a Unix shell, we should use types that have consistent behaviors across platforms. This pull request introduces unix_str and unix_path as dependencies that are used in place of OsStr(ing) and Path(Buf) from std.

Walkthrough

The recent changes to the yash_builtin and yash_env modules significantly improve error handling and path management by standardizing the use of Unix-specific string types and replacing standard library paths with custom implementations. This transition enhances compatibility, particularly in Unix-like environments, and consolidates error types for better robustness across the codebase.

Changes

Files Change Summary
yash-builtin/... Updated error handling to use yash_env::system::Errno and paths to yash_env::path::Path.
yash-env/... Introduced new exports for unix_path and unix_str, re-exporting existing types to improve usability.
yash-builtin/src/cd/... Transitioned from std::path to yash_env::path for all path-related functionality.
yash-semantics/... Adjusted path handling to utilize UnixString and UnixStr for Unix-specific string operations.

Poem

In the land of code, where paths intertwine,
A rabbit hops forth, with changes so fine.
From standard to custom, the strings now align,
Unix-style handling, oh how they shine! 🐇✨
With errors now clear, and paths that are bright,
Let’s celebrate progress, in day and in night!

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 .` - `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 generate interesting stats about this repository and render them as a table.` - `@coderabbitai show all the console.log statements in this repository.` - `@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 as 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. Additionally, you can add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. ### 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.
