[furusax0621]

The goaslog package should describe how to initialize loggers using log/slog, but currently it uses logrus.
I fixed it.

Walkthrough

This change signifies a shift in logging strategy within the goaslog package, transitioning from the logrus to the slog logger framework. This adjustment aims to configure the logger backend in a service, enhancing logging capabilities and potentially offering improvements in performance, usability, or feature set.

Changes

File(s)	Change Summary
logging/slog/adapter.go	Switched logging from logrus to slog in goaslog package.

🐇✨
In the realm of code, a rabbit hopped,
From logrus fields to slog it swapped.
With every line, it left a trace,
A leap towards efficiency, with grace.
In logs, it found a brand new space.

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-tests for this file.
• 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 tests 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 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 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.

• 9-11: The example usage in the documentation correctly demonstrates initializing the goaslog logger with slog. This change aligns with the PR's objective to guide developers towards using log/slog instead of logrus. It's crucial to ensure that the rest of the documentation throughout the project is updated to reflect this change if not already done.

The import statement for log/slog is correctly added, ensuring that the adapter uses the intended logging library. This change is essential for the adapter's functionality to align with the PR's objectives. It's also important to remove any logrus imports if they are no longer needed, although such changes are not visible in the provided diff.

The adapter struct definition is concise and clearly associates the slog.Handler with the adapter. This struct serves as the foundation for integrating slog with the goa framework, ensuring that logging calls within goa can be redirected to slog. The implementation appears to be straightforward and maintainable.

The logging functions (Info, InfoContext, Warn, WarnContext, Error, ErrorContext) are correctly implemented to use slog for logging. Each function appropriately handles context and logging levels, ensuring that the adapter can be used seamlessly within the goa framework. It's important to ensure that these functions are thoroughly tested, especially to verify that context and logging levels are handled as expected.

The New function implementation for creating a new logger instance with additional data is well-designed. It demonstrates a good understanding of slog's API, particularly in handling attributes. This function enhances the adapter's flexibility by allowing the creation of new logger instances with pre-defined attributes, which can be very useful in a structured logging context. It's recommended to add examples or documentation on how to use this function effectively.

The log function is the core of the adapter, handling the actual logging operation. The use of runtime.Callers to capture the caller's PC (Program Counter) is a sophisticated approach to include call site information in the logs. This detail is valuable for debugging. However, it's crucial to ensure that the offset passed to runtime.Callers (currently 4) is accurate, considering the call stack depth might vary based on how the logging functions are structured or if they are wrapped. Testing or documenting the rationale behind choosing this offset would be beneficial for maintainability.
