Clean up Cobra `Example` blocks by austin-denoble · Pull Request #41 · pinecone-io/cli

austin-denoble · 2025-09-30T02:30:27Z

Problem

We're working on improving the overall documentation experience around the CLI. One area that could use some attention are our Example blocks in our cobra.Command configurations. We're inconsistently using utilities in different commands, some commands need examples, etc. These are important because they're part of the self-documenting nature of the CLI, and are used when calling --help against a command, or generating man pages.

Solution

Improve the help.Examples helper function, move heredoc inside of it so we get easier expression at callsite.
Make sure our example commands are consistent in syntax and style. Update commands that need examples.
Add new unit tests for help.Examples to validate behavior.

After these updates, the examples that are printed with the --help flag should be consistently styled across all commands.

Before	After

Type of Change

Bug fix (non-breaking change which fixes an issue)
New feature (non-breaking change which adds functionality)
Breaking change (fix or feature that would cause existing functionality to not work as expected)
This change requires a documentation update
Infrastructure change (CI configs, etc)
Non-code change (docs, etc)
None of the above: (explain here)

Test Plan

Pull this branch down, build the binary with goreleaser, and run commands with --help to validate the output.

…so we get easier expression at callsite, make sure our example commands are consistently styled

Code Review Complete ✅

I've conducted a thorough review of the PR that cleans up Cobra Example blocks across 46 files. Here's my comprehensive feedback:

Review Checklist:

Read repository guidelines (CLAUDE.md)
Analyze core helper function changes in examples.go
Review command file changes for consistency
Check for potential bugs or issues
Assess performance considerations
Evaluate security concerns
Check test coverage implications
Provide comprehensive feedback

Overall Assessment: 🟢 Excellent Refactoring

This is a well-executed cleanup that significantly improves the CLI's documentation experience and maintainability.

Code Quality & Best Practices ✅

Strengths:

Excellent abstraction: The new help.Examples() function centralizes example formatting logic, reducing code duplication across 46 files
Clean API design: Changed from Examples([]string) to Examples(string) with heredoc support makes callsite code more readable
Consistent formatting: All command examples now follow a uniform pattern with proper indentation and styling
Good separation of concerns: Helper handles all formatting complexity while commands focus on content

Minor suggestions:

Consider adding a godoc example to internal/pkg/utils/help/examples.go:16 showing typical usage
The function signature could benefit from a more descriptive parameter name: func Examples(exampleBlock string) vs func Examples(examples string)

Implementation Analysis 🔍

Key improvements in examples.go:

Heredoc integration: Uses heredoc.Doc() to handle indentation normalization automatically
Smart line processing: Differentiates between comment lines (styled with Faint) and command lines (styled with CodeWithPrompt)
Whitespace handling: Properly trims trailing whitespace while preserving interior blank lines
Robust edge cases: Handles empty blocks gracefully

Command file updates:

Consistent replacement of heredoc.Doc() with help.Examples() across all commands
Removal of manual $ prompt prefixes (now handled by style.CodeWithPrompt)
Improved visual hierarchy with comments vs commands

Potential Issues 🟡

Very minor concerns:

Memory allocation: out := make([]string, 0, len(lines)) pre-allocates optimally, but could use len(lines) instead of 0 capacity for slightly better performance in typical cases
Error handling: Function doesn't validate malformed input, but this is acceptable for internal tooling
Consistency: Mixed indentation in some examples (tabs vs spaces) but the helper normalizes this anyway

Performance Considerations ⚡

Positive impacts:

Reduces code duplication across 46 files
Centralized logic means easier maintenance
String processing is efficient for typical CLI example sizes

No performance concerns: The string operations are lightweight and appropriate for CLI help text generation.

Security Concerns 🔒

No security issues identified:

No user input validation needed (internal tooling)
No external dependencies introduced beyond existing heredoc library
No credentials or sensitive data handling

Test Coverage 📊

Observations:

No existing tests for the help package utilities
The refactor maintains existing behavior, so regression risk is low
Consider adding tests for the new Examples() function to cover:
- Empty input handling
- Mixed content (comments + commands)
- Whitespace edge cases
- Heredoc normalization

Suggestion:

func TestExamples(t *testing.T) {
    // Test cases for comment/command differentiation,
    // empty blocks, whitespace handling, etc.
}

Specific File Feedback 📁

internal/pkg/utils/help/examples.go - Excellent implementation

Clean, readable, well-documented
Handles edge cases appropriately
Good use of existing style utilities

Command files - Consistent improvements

internal/pkg/cli/command/auth/clear.go:22-31 - Good example of clean conversion
internal/pkg/cli/command/index/create.go:82-91 - Complex examples handled well
All files show consistent application of the new pattern

Final Recommendation ✨

Approve and merge - This is a high-quality refactoring that:

Improves code maintainability
Enhances user experience with consistent help formatting
Reduces technical debt
Follows Go best practices
Maintains backward compatibility

The only enhancement I'd suggest is adding unit tests for the new helper function, but this shouldn't block merging since the behavior is well-defined and the risk is low.

 				createParams.Name = options.name

+			if len(options.roles) > 0 {


Fix for defaulting the appropriate role if a user hasn't passed any.

improve the help.Examples helper function, move heredoc inside of it …
