Walkthrough

A new Lua plugin file has been introduced to define syntax highlighting rules for a Rust-like language. The plugin specifies reserved keywords, arithmetic operators, and adds a custom comment string. No changes were made to control flow, error handling, or public API declarations.

Changes

File(s) Change Summary
Lua/Plugins/rs.lua Added new plugin for Rust-like syntax highlighting, defining keywords, operators, and a comment.

Poem

In a warren of code, a new script appears,
Rusty words now sparkle, as syntax clears.
Operators hop, keywords take flight,
Comments add flavor, in Lua’s soft light.
The rabbit approves—highlighting delight! 🐇✨

Tip

⚡️ Faster reviews with caching
  • CodeRabbit now supports caching for code and dependencies, helping speed up reviews. This means quicker feedback, reduced wait times, and a smoother review experience overall. Cached data is encrypted and stored securely. This feature will be automatically enabled for all accounts on May 16th. To opt out, configure Review - Disable Cache at either the organization or repository level. If you prefer to disable all data retention across your organization, simply turn off the Data Retention setting under your Organization Settings.

Enjoy the performance boost—your workflow just got faster.

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>, 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.

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

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.

1-4: Group reserved keywords into a table to reduce duplication.
Instead of individual highlight calls, consider:

local keywords = { "const", "fn", "let", "mut" }
for _, kw in ipairs(keywords) do
  highlight(kw, "reserved")
end

This makes it easier to add or remove keywords.
Also consider expanding with other Rust keywords like struct, enum, impl, etc.


5-9: Consolidate operator highlighting and extend coverage.
Group operators into a list and loop:

local ops = { "+", "-", "*", "/", "%" }
for _, op in ipairs(ops) do
  highlight(op, "operator")
end

Additionally, you may want to include comparison (==, !=, <, >) and bitwise (&, |, ^, <<, >>) operators for fuller Rust support.

⚠️ Potential issue

Use proper comment delimiter(s) for Rust syntax highlighting.
The current call add_comment("add some raw pointers trust") appears to be placeholder text rather than actual Rust comment syntax. To ensure comments are highlighted, register the real comment tokens. For example:

-add_comment("add some raw pointers trust")
+add_comment("//")         -- single-line comments
+add_comment("/*")         -- block comment start (if supported)
+add_comment("*/")         -- block comment end (if supported)

Without valid delimiters, comment highlighting won’t function.

📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
add_comment("add some raw pointers trust")
add_comment("//") -- single-line comments
add_comment("/*") -- block comment start (if supported)
add_comment("*/") -- block comment end (if supported)
