PR Review: swap-shakacode-deps Gem Structure and Documentation

Thank you for this well-organized PR! This is an excellent foundation for creating a globally installable dependency swapping tool. Here's my comprehensive review:

✅ Strengths

  1. Excellent Documentation: The README, USAGE_EXAMPLES, and implementation plan are thorough and well-written
  2. Clear Architecture: The module structure is well-thought-out and follows Ruby conventions
  3. Comprehensive CLI Design: The CLI interface in lib/swap_shakacode_deps/cli.rb covers all the features from the existing tool
  4. Proper Gem Structure: Follows standard Ruby gem conventions with appropriate files and structure
  5. Good Error Hierarchy: Error classes are properly defined with specific error types

🐛 Potential Issues

Critical Issues

  1. Missing Implementation Files (swap-shakacode-deps/lib/swap_shakacode_deps.rb:5-12)

    The main module requires several files that don't exist yet:

    • github_spec_parser.rb
    • backup_manager.rb
    • cache_manager.rb
    • watch_manager.rb
    • gem_swapper.rb
    • npm_swapper.rb
    • config_loader.rb
    • swapper.rb

    Impact: The gem won't load/run until these are implemented.

    Recommendation: Either implement stub versions of these classes or remove the requires until they're ready. For now, I'd suggest adding TODO comments and having the CLI display a "not yet implemented" message.

  2. Gemfile Missing Newline (swap-shakacode-deps/Gemfile:6)

    The file ends without a newline character.

    Fix: Add a newline at the end of the file (Ruby style guide requirement).

  3. LICENSE Missing Newline (swap-shakacode-deps/LICENSE:21)

    Same issue as Gemfile.

  4. Rakefile Missing Newline (swap-shakacode-deps/Rakefile:13)

    Same issue.

Medium Priority Issues

  1. Gemspec Repository URL (swap-shakacode-deps/swap-shakacode-deps.gemspec:17,22-23)

    The gemspec references https://github.com/shakacode/swap-shakacode-deps but this appears to be a new gem. Should this be under the same repo or a separate one?

    Recommendation: Verify the intended repository structure. If this is staying in react_on_rails-demos, update the URLs accordingly.

  2. YAML Dependency (swap-shakacode-deps/swap-shakacode-deps.gemspec:34)

    You're requiring yaml gem version ~> 0.2, but YAML is part of Ruby's standard library as of Ruby 2.7+.

    Recommendation: Remove this dependency. YAML is built-in and doesn't need to be declared. You can just use require 'yaml'.

  3. Error Handling in CLI (swap-shakacode-deps/lib/swap_shakacode_deps/cli.rb:255-257)

    The infer_gem_from_repo method raises ValidationError, but ValidationError is defined in error.rb. However, the error message could be clearer.

    Enhancement: Consider showing supported repository patterns in the error message.

🔒 Security Considerations

Low Risk Issues

  1. Path Traversal Prevention

    The CLI accepts arbitrary paths via --path, --shakapacker, etc. When implementing the actual file operations, ensure you:

    • Validate that paths don't escape intended directories
    • Handle symlinks carefully
    • Sanitize user-provided paths before file operations

    Note: This is for future implementation, not current code.

  2. GitHub Repository Input

    The --github option accepts repository names. When implementing:

    • Validate repository format to prevent command injection
    • Use safe shell escaping when running git commands
    • Consider rate limiting for GitHub operations
  3. File Backup Safety

    When implementing backup/restore:

    • Ensure atomic file operations
    • Validate backup file integrity before restoring
    • Implement proper file locking to prevent concurrent modifications

🚀 Performance Considerations

  1. Recursive Processing

    The --recursive flag could process many directories. When implementing:

    • Add progress indicators for large directory trees
    • Consider parallelization for independent projects
    • Add limits to prevent runaway processing
  2. GitHub Caching

    Good that you've planned for caching at ~/.cache/swap-shakacode-deps/. Consider:

    • Implementing cache invalidation strategies
    • Adding cache size limits
    • Cleaning up old/unused cached repos automatically

📝 Test Coverage

Critical Gap

  1. No Tests Present

    The PR includes RSpec configuration but no actual test files.

    Recommendation: Before the next PR, add at least:

    • Unit tests for CLI option parsing
    • Tests for error handling
    • Integration tests for the main workflows (once implemented)

    Even stub/placeholder tests would be valuable to establish testing patterns.

💡 Code Quality Suggestions

  1. RuboCop Compliance (swap-shakacode-deps/lib/swap_shakacode_deps/cli.rb:6,33,71)

    The code already has RuboCop disable comments for metrics. This is acceptable for now, but when implementing:

    • Consider extracting some methods to reduce complexity
    • The run! method could delegate to smaller, single-purpose methods
    • The parse_options! method could be split into logical sections
  2. Constant Organization (swap-shakacode-deps/lib/swap_shakacode_deps/cli.rb:8)

    Consider moving CONFIG_FILE to the main module as SwapShakacodeDeps::CONFIG_FILE for consistency with other constants.

  3. Date Placeholder in CHANGELOG (swap-shakacode-deps/CHANGELOG.md:10)

    The date shows 2024-01-XX. Update this to the actual release date or remove the version entry until release.

  4. Gemfile.lock Platform

    The Gemfile.lock includes platform-specific entries (arm64-darwin-24). Consider:

    • Adding a .gitignore entry or
    • Using bundle lock --add-platform ruby to ensure cross-platform compatibility

📋 Documentation

  1. Missing Development Docs

    Consider adding:

    • DEVELOPMENT.md with instructions for working on the gem itself
    • Architecture decision records (ADRs) for key design choices
    • Contributing guidelines specific to this gem
  2. README Examples (swap-shakacode-deps/README.md)

    The README is excellent! One suggestion:

    • Add a troubleshooting section for common errors during development
    • Include version compatibility matrix (Ruby versions, gem versions)

✨ Best Practices Adherence

Excellent Work On:

  • Frozen string literals in all Ruby files ✓
  • Proper module namespacing ✓
  • Clear separation of concerns in CLI design ✓
  • Comprehensive help text and examples ✓
  • MIT License (standard and appropriate) ✓
  • Semantic versioning plan ✓
  • MFA requirement in gemspec metadata ✓

🎯 Summary and Recommendations

This PR provides an excellent foundation for the swap-shakacode-deps gem. The documentation and structure are solid, making it easy to understand the intended functionality.

Before Merging:

  1. Can merge as-is if this is intentionally a documentation/planning PR
  2. Add missing newlines to Gemfile, LICENSE, and Rakefile
  3. Verify repository URLs in gemspec
  4. Remove YAML gem dependency

For Next PR:

  1. Implement stub classes for all required files, or update requires to be conditional
  2. Add basic test coverage
  3. Consider extracting implementation from existing bin/swap-deps script
  4. Update CHANGELOG date or mark version as unreleased

Overall Assessment:

Excellent work! This PR demonstrates thoughtful planning and good Ruby practices. The transition from a project-specific script to a global gem is well-designed. I'm excited to see the implementation in future PRs.

26-27: Consider refining the file glob pattern.

The File::FNM_DOTMATCH flag will include hidden files (like .DS_Store or .git*) in the gem package. Consider using a more explicit pattern or adding exclusions.

Example refinement:

-  spec.files = Dir.glob('{bin,lib}/**/*', File::FNM_DOTMATCH) +
-               %w[README.md LICENSE CHANGELOG.md]
+  spec.files = Dir.glob('{bin,lib}/**/*') +
+               %w[README.md LICENSE CHANGELOG.md]

Or use git ls-files for precise control:

-  spec.files = Dir.glob('{bin,lib}/**/*', File::FNM_DOTMATCH) +
-               %w[README.md LICENSE CHANGELOG.md]
+  spec.files = Dir.chdir(File.expand_path(__dir__)) do
+    `git ls-files -z`.split("\x0").reject { |f| f.match(%r{^(test|spec|features)/}) }

Fix config discovery to honor --path and home configs

File.join leaves ~ untouched, so --apply --path ~/app never finds the config even when it exists. We also never consult ~/.swap-deps.yml, yet the docs rely on that location. Both gaps break common workflows.

Please normalize the candidate paths with File.expand_path and include the home-directory fallback:

-      if @options[:target_path]
-        config_path = File.join(@options[:target_path], CONFIG_FILE)
-        return config_path if File.exist?(config_path)

Home-directory config example currently fails

The CLI only looks for .swap-deps.yml in the target directory or the current working directory, so this workflow against ~/.swap-deps.yml will always raise “Config file not found.” Please either revise the docs or (preferably) extend find_config_file to search the user’s home directory so the documented behavior works.

Based on thorough code review, made the following improvements:

## Added Files
- .gitignore: Standard Ruby gem gitignore with IDE and OS files
- .swap-deps.yml.example: Example configuration file with documentation
- Stub implementation modules for all required classes:
  - BackupManager: File backup/restore operations
  - CacheManager: GitHub repository cache management
  - WatchManager: NPM watch process management
  - GemSwapper: Gemfile dependency manipulation
  - NpmSwapper: package.json dependency manipulation
  - ConfigLoader: YAML configuration file handling
  - GitHubSpecParser: GitHub repo spec parsing
  - Swapper: Main orchestrator class

## Fixed Issues
- Removed yaml gem dependency (YAML is in Ruby stdlib)
- Updated CHANGELOG to mark version as [Unreleased]
- Removed Gemfile.lock (shouldn't be committed for libraries)
- Added stub implementations with TODOs for next iteration
- All modules show helpful "not yet implemented" messages
- Fixed RuboCop offenses (unused params, code style)
- Added RuboCop disables for acceptable complexity metrics

## Implementation Notes
Each module contains:
- Clear class/module documentation
- TODO comments referencing source implementation
- Basic structure and method signatures
- NotImplementedError or informative messages for users

This allows the gem to load and run, displaying helpful messages
about upcoming functionality rather than crashing with missing files.

✅ Code Review Feedback Addressed

Thank you for the thorough code review! I've addressed all the critical and medium priority issues:

Fixed Issues:

  1. Added stub implementation files - All required modules now exist with helpful "not yet implemented" messages
  2. Removed yaml gem dependency - YAML is indeed part of Ruby stdlib
  3. Updated CHANGELOG - Marked version as [Unreleased] instead of a placeholder date
  4. Removed Gemfile.lock - Shouldn't be committed for libraries
  5. Added .gitignore - Standard Ruby gem gitignore with IDE and OS files
  6. Added .swap-deps.yml.example - Example configuration with documentation
  7. Fixed all RuboCop offenses - Code style issues corrected, complexity metrics disabled where acceptable

Implementation Structure:

Each stub module includes:

  • Clear class/module documentation
  • TODO comments referencing the source implementation
  • Basic method signatures matching the expected interface
  • Informative messages for users when they try the commands

Next Steps:

The gem can now be loaded and run without errors. Users will see helpful messages about upcoming functionality. The next PR will focus on extracting and implementing the actual swapping logic from the existing demo_scripts code.

This approach allows for:

  • Incremental development and review
  • Early testing of the gem structure
  • Clear separation between planning/structure and implementation phases

Code Review - PR #54: Create swap-shakacode-deps gem structure and documentation

Thank you for this comprehensive PR! This is a well-structured foundation for extracting the swap-deps functionality into a standalone gem. Below is my detailed review:


🎯 Overall Assessment

This PR provides an excellent skeleton structure and planning documentation for the new gem. The approach of creating the structure first before implementing the logic is sound and makes the architecture review straightforward.

Summary: ✅ Approved with suggestions - The structure is solid, but there are areas for improvement before implementation begins.


✅ Strengths

1. Excellent Documentation

  • Comprehensive README with clear examples and use cases
  • Detailed implementation plan outlining the migration strategy
  • USAGE_EXAMPLES.md demonstrates real-world workflows effectively
  • CHANGELOG follows Keep a Changelog format

2. Well-Organized Structure

  • Clean separation of concerns across modules (CLI, Swapper, BackupManager, CacheManager, etc.)
  • Logical file organization following Ruby gem conventions
  • Proper use of module namespacing

3. CLI Design

  • lib/swap_shakacode_deps/cli.rb:1-327: Comprehensive option parsing with excellent help text
  • Good balance of features: dry-run, verbose, status reporting, etc.
  • Clear error handling structure with custom error types

4. Configuration Management

  • .swap-deps.yml.example provides clear guidance for users
  • Good examples mixing local paths and GitHub repos

🔍 Issues & Concerns

1. Critical: Missing Implementation (Expected)

All core modules contain NotImplementedError or placeholder messages. While this is acknowledged in the PR description, ensure the next phase implementation is tracked:

  • lib/swap_shakacode_deps/swapper.rb:30-47: Swap functionality placeholder
  • lib/swap_shakacode_deps/backup_manager.rb:16: Backup logic not implemented
  • lib/swap_shakacode_deps/gem_swapper.rb:16: Gem swapping logic missing
  • lib/swap_shakacode_deps/npm_swapper.rb:16: NPM swapping logic missing

Recommendation: Create GitHub issues for each module implementation to track progress in Phase 2.

2. Security Considerations

File Path Handling

The CLI accepts arbitrary file paths without validation:

# swap-shakacode-deps/lib/swap_shakacode_deps/cli.rb:80-90
opts.on('--shakapacker PATH', 'Path to local shakapacker repository') do |path|
  @gem_paths['shakapacker'] = path
end

Recommendations:

  • Add path validation and expansion before use
  • Check for path traversal attempts
  • Validate that paths point to actual gem directories
  • Ensure paths are within reasonable bounds (not system directories)

GitHub Repository Validation

lib/swap_shakacode_deps/cli.rb:228-242: The parse_github_option method performs basic parsing but lacks validation:

Issues:

  • No validation that repo matches org/repo format
  • Branch/tag names not validated against Git naming rules
  • Potential for injection if these values are used in shell commands later

Recommendations:

  • Validate repo format: /^[\w-]+\/[\w-]+$/
  • Validate branch/tag names against Git ref rules
  • Document the planned implementation of validate_github_repo and validate_github_branch in github_spec_parser.rb

Shell Command Execution (Future Risk)

Since this tool will eventually run bundle install, npm install, and potentially git commands, ensure:

  • All paths and arguments are properly escaped
  • Use Ruby's Shellwords.escape or avoid shell execution entirely
  • Never interpolate user input directly into shell commands

3. Code Quality Issues

RuboCop Violations

Multiple RuboCop disables without justification:

  • lib/swap_shakacode_deps/cli.rb:6: Metrics/ClassLength disabled
  • lib/swap_shakacode_deps/cli.rb:33: Multiple complexity metrics disabled

Recommendation: Consider refactoring to avoid needing these disables. The CLI class could be split:

  • OptionParser logic → separate CliParser class
  • Command handlers → separate CommandDispatcher class
  • This would improve maintainability and testability

Inconsistent Error Handling

lib/swap_shakacode_deps/cli.rb:59-66: Error handling catches both custom and standard errors, but the distinction isn't clear.

Recommendation: Document which errors are expected vs unexpected, or add logging.

4. Missing Test Coverage

No test files are included in this PR. While the PR description mentions tests will come in Phase 2, consider:

  • Adding a spec/ directory structure now
  • Including at least basic test setup/configuration
  • Creating skeleton test files to guide implementation

Recommendation: Add skeleton test structure with spec_helper.rb

5. Dependency Concerns

Gemspec Dependencies

swap-shakacode-deps/swap-shakacode-deps.gemspec:33: Only one runtime dependency:

spec.add_dependency 'json', '~> 2.0'

Questions:

  • Will YAML parsing use stdlib only?
  • Are there dependencies for file manipulation, git operations, or process management that should be declared?
  • Consider if additional gems would improve implementation (e.g., git, tty-* for better CLI UX)

6. Configuration File Location

lib/swap_shakacode_deps/cli.rb:315-323: Config file discovery logic doesn't check parent directories or home directory.

Recommendation: Consider a search order like:

  1. --path directory if specified
  2. Current directory
  3. Parent directories (up to git root or home)
  4. ~/.swap-deps.yml

7. Documentation Gaps

Missing Sections

  • README.md: No section on contributing, testing, or releasing
  • README.md: No information about minimum Ruby/Node versions required
  • No CONTRIBUTING.md file

Unclear Behavior

  • What happens if a gem is already swapped and you swap again?
  • How does restore work if multiple backups exist?
  • What's the behavior with --recursive and conflicting configs?

🎨 Best Practices & Suggestions

1. Add Version Check

Consider adding a check for compatible Ruby versions at runtime, not just in gemspec.

2. Better User Feedback

When implemented, ensure clear progress indicators:

  • Show which files are being modified
  • Indicate when operations complete successfully
  • Provide actionable error messages with solutions

3. Idempotency

Document whether operations are idempotent:

  • Can you run swap twice?
  • Can you restore then restore again?
  • What's the expected behavior?

4. Integration with Bundler

Consider whether this should integrate with bundle config local.* functionality, which provides similar features for local gem development.

5. Atomic Operations

lib/swap_shakacode_deps/backup_manager.rb:25: Comment mentions file locking. Ensure:

  • Backups are created atomically
  • Failed swaps can be rolled back completely
  • Concurrent runs don't corrupt state

📊 Performance Considerations

1. GitHub Cache Strategy

lib/swap_shakacode_deps/cache_manager.rb:16: Cache management is mentioned but not implemented.

Recommendations:

  • Use git clone --depth 1 for faster cloning
  • Implement cache expiration strategy
  • Consider using git worktree for multiple branch testing

2. Recursive Processing

lib/swap_shakacode_deps/swapper.rb:86-94: The recursive file discovery could be slow in large directories.

Recommendations:

  • Add progress indicator for recursive operations
  • Consider adding --exclude patterns (node_modules, vendor, etc.)
  • Limit recursion depth

🧪 Test Coverage Recommendations

When implementing tests in Phase 2:

  1. Unit Tests:

    • CLI option parsing
    • GitHub spec parsing
    • Path validation
    • Config loading
  2. Integration Tests:

    • Full swap/restore cycle
    • Config file application
    • Error recovery
  3. Edge Cases:

    • Missing files
    • Invalid permissions
    • Malformed config files
    • Concurrent runs

📋 Checklist for Next Phase

Before merging Phase 2 implementation:

  • Implement path validation and sanitization
  • Add input validation for all user-supplied values
  • Implement proper shell command escaping
  • Add comprehensive test coverage (>80%)
  • Add integration tests with real gem swapping
  • Document security considerations
  • Add CONTRIBUTING.md with development setup
  • Consider adding GitHub Actions CI workflow
  • Test on all supported platforms (macOS, Linux, WSL)
  • Audit for any security vulnerabilities

🎉 Conclusion

This is a well-planned and well-documented PR that sets up an excellent foundation for the swap-shakacode-deps gem. The architecture is sound, the documentation is thorough, and the separation of concerns is clean.

The main areas needing attention are:

  1. Security: Input validation and safe command execution
  2. Testing: Test structure and coverage planning
  3. Refactoring: Consider breaking up the large CLI class

Once the implementation is complete with proper security measures and tests, this will be a valuable tool for the Shakacode ecosystem.

Recommendation: ✅ Merge this PR to establish the structure, then create detailed issues for Phase 2 implementation with focus on security and testing.

🧹 Nitpick comments (7)
swap-shakacode-deps/swap-shakacode-deps.gemspec (1)

25-27: Filter out directories from spec.files.

Dir.glob with File::FNM_DOTMATCH pulls in ./.. entries and directories, so gem build will warn that those aren’t files. Drop the directories when constructing spec.files.

-  spec.files = Dir.glob('{bin,lib}/**/*', File::FNM_DOTMATCH) +
-               %w[README.md LICENSE CHANGELOG.md]
+  spec.files = Dir.glob('{bin,lib}/**/*', File::FNM_DOTMATCH)
+                 .reject { |f| File.directory?(f) } +
+               %w[README.md LICENSE CHANGELOG.md]
swap-shakacode-deps/lib/swap_shakacode_deps/gem_swapper.rb (1)

32-39: Consider error handling for bundle install failures.

The system call does not check the return value, so bundle install failures will be silent. In dry-run mode this is acceptable, but when actually installing, failures should be detected and reported.

Consider this approach:

 def run_bundle_install(path)
   return if @dry_run

   puts '  Running bundle install...'
   Dir.chdir(path) do
-    system('bundle', 'install', '--quiet')
+    success = system('bundle', 'install', '--quiet')
+    puts '  ⚠️  bundle install failed' unless success
   end
 end

Alternatively, for more robust error handling in the full implementation, consider raising an error on failure or returning a status indicator that the caller can check.

swap-shakacode-deps/lib/swap_shakacode_deps/npm_swapper.rb (2)

27-34: Consider error handling for npm install failures.

Similar to the bundle install concern, the system call does not check the return value. npm install failures will be silent, which could lead to incomplete or broken dependency states.

Apply this pattern:

 def run_npm_install(path)
   return if @dry_run

   puts '  Running npm install...'
   Dir.chdir(path) do
-    system('npm', 'install', '--silent')
+    success = system('npm', 'install', '--silent')
+    puts '  ⚠️  npm install failed' unless success
   end
 end

37-44: Consider error handling for npm build failures.

The build command also lacks error checking. Build failures should be reported to avoid confusion when the swap appears to succeed but the package is not properly built.

 def build_npm_package(gem_name, npm_path)
   return if @dry_run

   puts "  Building #{gem_name}..."
   Dir.chdir(npm_path) do
-    system('npm', 'run', 'build')
+    success = system('npm', 'run', 'build')
+    puts "  ⚠️  Build failed for #{gem_name}" unless success
   end
 end
swap-shakacode-deps/lib/swap_shakacode_deps/config_loader.rb (1)

27-37: Consider simplifying the validation logic.

The validation logic for the github section is correct but uses an inverted guard clause that reduces readability. The pattern return unless condition followed by raise is less clear than a direct conditional check.

 def validate_config(config)
   raise ConfigError, 'Configuration must be a hash' unless config.is_a?(Hash)

   # Validate gems section if present
   raise ConfigError, 'gems section must be a hash' if config['gems'] && !config['gems'].is_a?(Hash)

   # Validate github section if present
-  return unless config['github'] && !config['github'].is_a?(Hash)
-
-  raise ConfigError, 'github section must be a hash'
+  raise ConfigError, 'github section must be a hash' if config['github'] && !config['github'].is_a?(Hash)
 end
swap-shakacode-deps/lib/swap_shakacode_deps/watch_manager.rb (2)

8-8: Extract CACHE_DIR to eliminate duplication.

The CACHE_DIR constant is defined identically in both WatchManager and CacheManager. Extract it to a shared module or base class to maintain a single source of truth.

Consider creating a shared configuration module:

module SwapShakacodeDeps
  module Paths
    CACHE_DIR = File.expand_path('~/.cache/swap-shakacode-deps')
  end
end

Then reference it as Paths::CACHE_DIR in both classes.


17-30: Consider consistent stub implementation approach.

The stub methods use two different patterns: list_processes and kill_processes print informative messages, while spawn_watch_process raises NotImplementedError. For consistency and better user experience, consider using the same approach across all stub methods.

If you prefer the informative message approach:

 def spawn_watch_process(gem_name, npm_path)
-  raise NotImplementedError, 'Watch process spawning will be implemented in the next iteration'
+  puts 'ℹ️  Watch process spawning will be implemented in the next iteration'
 end

swap-shakacode-deps/.gitignore (1)

1-70: Comprehensive ignore list looks good.

The patterns cover typical Ruby gem, tooling, and OS artifacts—nothing concerning here.

swap-shakacode-deps/.swap-deps.yml.example (1)

1-36: LGTM - Well-documented configuration example.

The example configuration file is clear, well-structured, and provides helpful inline documentation. The format aligns with the ConfigLoader implementation and includes practical examples for both local paths and GitHub repositories.

swap-shakacode-deps/lib/swap_shakacode_deps/github_spec_parser.rb (1)

5-22: Consider method visibility for module usage.

The GitHubSpecParser is defined as a module with instance methods. Depending on the intended usage pattern, you may want to make these methods callable directly on the module using module_function or defining them as self.method_name.

If these methods are intended to be called as GitHubSpecParser.parse_github_spec(...) rather than via inclusion/extension, they should be module methods:

 module GitHubSpecParser
   # TODO: Extract implementation from demo_scripts/github_spec_parser.rb

   # Parses GitHub spec: org/repo, org/repo#branch, or org/repo@tag
-  def parse_github_spec(github_spec)
+  def self.parse_github_spec(github_spec)
     raise NotImplementedError, 'GitHub spec parsing will be implemented in the next iteration'
   end

   # Validates GitHub repository format (org/repo)
-  def validate_github_repo(repo)
+  def self.validate_github_repo(repo)
     raise NotImplementedError, 'GitHub repo validation will be implemented in the next iteration'
   end

   # Validates GitHub branch name according to Git ref naming rules
-  def validate_github_branch(branch)
+  def self.validate_github_branch(branch)
     raise NotImplementedError, 'GitHub branch validation will be implemented in the next iteration'
   end
 end

Alternatively, if the methods are intended for inclusion/extension (mix-in pattern), the current structure is appropriate. Please verify the intended usage pattern when implementing these methods.

swap-shakacode-deps/lib/swap_shakacode_deps/backup_manager.rb (1)

26-33: LGTM - Utility methods are well-implemented.

The backup_exists? and list_backups helper methods are correctly implemented and will work well once the backup/restore operations are added.

swap-shakacode-deps/lib/swap_shakacode_deps/cache_manager.rb (1)

31-40: LGTM - Cache path utilities are well-structured.

The github_cache_path method correctly transforms repository and branch names into filesystem-safe slugs, and cache_exists? provides a simple existence check. The implementation aligns with the expected usage from the Swapper class.

swap-shakacode-deps/lib/swap_shakacode_deps/swapper.rb (3)

9-24: LGTM - Well-structured orchestrator initialization.

The initialization properly sets up all the component managers and swappers, with sensible defaults for options. The use of keyword arguments and splatting options to sub-components creates a flexible and maintainable architecture.


57-75: LGTM - Robust configuration loading with good defaults.

The load_config method properly normalizes configuration from YAML, handling both string and symbol keys defensively, and applying sensible defaults (branch: 'main', ref_type: :branch). The defensive key access pattern (info['repo'] || info[:repo]) is good practice for configuration handling.


85-94: LGTM - Clean project discovery logic.

The find_projects method correctly handles both recursive and non-recursive modes, with appropriate file existence checks. The recursive glob pattern will properly discover all Gemfile locations in the directory tree.

⚠️ Potential issue | 🟠 Major

Add input validation for pid parameter.

The method uses Process.kill(0, pid) which expects an integer PID. If pid is nil, non-integer, or invalid, this could raise unexpected errors like TypeError or ArgumentError that aren't handled.

Apply this diff to add validation:

 def process_running?(pid)
+  return false if pid.nil? || !pid.is_a?(Integer) || pid <= 0
+  
   Process.kill(0, pid)
   true
 rescue Errno::ESRCH
   false
 rescue Errno::EPERM
   true # Process exists but we don't have permission

to 40, add input validation for the pid parameter so non-integer, nil, or
otherwise invalid PIDs don't raise unexpected errors: first check that pid is
present and is a positive Integer (or, if you want to accept numeric strings,
normalize with to_i and verify > 0), return false immediately for invalid
values, then call Process.kill(0, pid) as before; also catch TypeError and
ArgumentError in the rescue chain and return false so only the expected
ESRCH/EPERM behaviors remain.
