📝 Walkthrough

Walkthrough

The pull request adds clarifying comments to the RegisterModule function in the depinject/appconfig/module.go file. The comments explain the behavior of module registration, specifically highlighting that a module can be manually overwritten in the global module registry by calling RegisterModule again with the same configuration but different options. The changes focus on improving documentation about protobuf message types for module configuration and provide guidance on defining module options for better debugging.

🪧 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>, 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.

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.

20-23: Consider enhancing documentation with examples and risk warning.

To make the documentation even more helpful, consider:

1. Adding a code example demonstrating how to wrap a default module
2. Including a warning about potential risks when overwriting modules in the global registry

Example addition:

 // In some cases, a module may need to be manually overwritten from the global module
 // registry. This can be done by calling RegisterModule again with the same config,
 // but different options. This is useful when wrapping default modules.
+//
+// For example, to wrap a default bank module:
+//   RegisterModule(banktypes.Module{},
+//     Provide(
+//       func(m *banktypes.Module) CustomBankModule {
+//         return WrapBankModule(m)
+//       },
+//     ),
+//   )
+//
+// Note: Exercise caution when overwriting modules as it affects the global state
+// and may impact other parts of the application that depend on the original module.

20-23: Documentation clearly explains module overwriting capability.

The added documentation effectively clarifies how modules can be manually overwritten in the global registry, which is particularly useful for module wrapping scenarios.
