Poem

🐇 In the meadow where constants play,
New characters brighten up the day!
Strings dance lightly, no more dismay,
Robust helpers, come what may.
With tests that hop and always stay,
Code now leaps in a joyous way! 🌼

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.
    • @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.

182-189: Test implementation looks good!

The testEscapePercentEqualAnd method effectively tests the escape and unescape functionality for special characters.

tracer-core/src/main/java/com/alipay/common/tracer/core/utils/StringUtils.java (6)

60-61: Addition of INDEX_NOT_FOUND is beneficial.

The introduction of the INDEX_NOT_FOUND constant standardizes the representation of a not-found index, improving code readability.


79-86: isEmpty and isNotEmpty methods are well-implemented.

These methods offer concise checks for string emptiness, improving utility and readability.


234-250: Enhancement to handle null inputs is effective.

The escapePercentEqualAnd method now gracefully handles null inputs by returning an empty string, improving robustness.


491-494: Overload for replace method adds useful functionality.

The new overload allows specifying a maximum number of replacements, offering more control over string manipulation.


591-604: Enhancements to indexOf and indexOfIgnoreCase methods improve flexibility.

By accepting CharSequence, these methods can handle a wider range of input types.

Also applies to: 638-659


672-717: regionMatches method enhances string comparison capabilities.

The new method provides a nuanced approach to matching substrings with an option for case sensitivity.
