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.
  • @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.

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 an incremental review. This is useful when automatic reviews are disabled for the repository.
• @coderabbitai full review to do a full review from scratch and review all the files again.
• @coderabbitai summary to regenerate the summary of the PR.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai configuration to show the current CodeRabbit configuration for the repository.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configuration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
• Please see the configuration documentation for more information.
• If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/schema.v2.json

I ran this feature locally, the strings do not be printed one by one, did I miss something?

facades.Route().Get("/stream", func(ctx http.Context) http.Response {
  b := []string{"a", "b", "c"}
  return ctx.Response().Stream(func(w http.StreamWriter) error {
    for _, a := range b {
      if _, err := w.Write([]byte(a)); err != nil {
	return err
      }
      
      if err := w.Flush(); err != nil {
	return err
      }
      
      time.Sleep(1 * time.Second)
    }
    
    return nil
  }, 200)
})

    }
    
    return nil
  }, 200)
})

When you use Flush, buffered content only be displayed after reaching to newline.

...
if _, err := w.Write([]byte(a + "\n")); err != nil {
     return err
}
...

@kkumar-gcc I changed it, but doesn't have an effect.

facades.Route().Get("/stream", func(ctx http.Context) http.Response {
		b := []string{"a", "b", "c", "c", "c", "c", "c"}
		return ctx.Response().Stream(func(w http.StreamWriter) error {
			for _, a := range b {
				if _, err := w.Write([]byte(a + "\n")); err != nil {
					return err
				}

				if err := w.Flush(); err != nil {
					return err
				}

				time.Sleep(1 * time.Second)
			}

			return nil
		}, 200)
	})
