Walkthrough

This update enhances the project by introducing new tokenization features in both Python and Rust, alongside benchmarking tests for performance comparison. It also improves project organization by updating the .gitignore file and adding necessary dependencies in Rust's Cargo.toml.

Changes

File(s)	Change Summary
.gitignore	Added entries to ignore __pycache__ and .hypothesis directories.
Cargo.toml	Added cached, regex, lazy_static dependencies.
benchmark/py_token.py, src/tokenizer.rs	Introduced new tokenization functionality using regular expressions.
benchmark/test_benchmark_regex.py	Added benchmark tests for Python and Rust regex tokenizers.
src/lib.rs, src/main.rs	Enhanced Rust functionality with new modules and simple programs.

🐰✨
Oh hoppity day, a fresh update's here!
New tools in our box, oh so dear.
Regex dances, tokens align,
In Python and Rust, our code does shine.
Celebrate the craft, for progress we cheer!

Additional comments not posted (6)

src/main.rs (1)

1-4: Simple demonstration of text splitting in Rust.

Consider adding more comprehensive examples or integration with the newly added tokenizer modules to showcase their functionality.

Cargo.toml (1)

12-14: Addition of dependencies suitable for tokenization tasks.

Ensure that the versions of the dependencies are compatible with the project's Rust edition and other dependencies.

src/lib.rs (1)

7-25: Integration of new tokenizer functions into the bleuscore module.

Ensure robust error handling, especially when interfacing with Python, to maintain system stability and provide clear error messages to users.

benchmark/test_benchmark_regex.py (1)

10-56: Benchmark tests comparing Python and Rust tokenizer implementations.

Consider adding more diverse test cases to cover edge cases and unusual inputs, ensuring a comprehensive evaluation of tokenizer performance.

src/tokenizer.rs (1)

6-90: Implementation of Rust tokenizers with regex and caching.

Consider adding comments explaining the regex patterns and their intended matches for better maintainability and understanding of the code.

benchmark/py_token.py (1)

20-107: Implementation of Python tokenizers with regex and caching.

Consider adding more detailed documentation for the tokenization methods to aid future developers and users in understanding the code's functionality.

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>.
  • 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.

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 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.
