lib/patches/hash.rb (1)
4-7: Effective implementation ofsymbolize_keys, consider refactoring error handlingThe
symbolize_keysmethod effectively converts all keys to symbols while handling potential errors. However, the use of a rescue modifier, while compact, can reduce readability.Consider refactoring to use a block form of error handling for improved clarity:
def symbolize_keys transform_keys do |key| begin key.to_sym rescue key end end endThis approach maintains the functionality while improving readability and removing the need for the Rubocop disable comment.
lib/patches/string.rb (2)
21-24: Approve changes with suggestions for improvementThe updated
underscoremethod significantly improves the string conversion functionality. However, I have a few suggestions:
The comment "Copied from Rails" might be misleading if the implementation has been modified. Consider updating it to "Adapted from Rails" or add a note about any modifications.
The method doesn't handle non-ASCII characters, which could be a limitation in some cases. Consider adding a note about this limitation in the method's documentation.
To improve clarity, consider adding examples in the method's documentation to illustrate its behavior with different input types (e.g., namespaced constants, mixed case strings, strings with hyphens).
Would you like me to provide an example of how the documentation could be improved with these suggestions?

1-1: Consider explaining rubocop disablesThe file uses rubocop disable comments for
Style/OptionalBooleanParameterandLint/UnderscorePrefixedVariableName. While it's good that these are scoped to just this file, it would be helpful to add a brief comment explaining why these rules are disabled. This can help future maintainers understand the reasoning behind these exceptions.Would you like me to suggest a format for adding these explanations?

lib/core/terraform_config/generator.rb (2)
31-32: LGTM: Consistent handling of secret configurations.The addition of the "secret" case in the
tf_configmethod is consistent with the existing pattern and correctly calls the newsecret_configmethod.For consistency with the other cases, consider using a single-line format:
when "secret" then secret_config
71-79: LGTM: Well-structured secret configuration method.The
secret_configmethod is implemented correctly and consistently with other configuration methods in the class. It properly initializes aTerraformConfig::Secretinstance with the necessary attributes from thetemplateobject.Consider adding error handling or validation to ensure the
templateobject contains all required attributes. This could prevent potential runtime errors if the template is malformed. For example:def secret_config required_keys = %w[name description type data tags] missing_keys = required_keys - template.keys raise ArgumentError, "Missing required keys: #{missing_keys.join(', ')}" unless missing_keys.empty? TerraformConfig::Secret.new( name: template["name"], description: template["description"], type: template["type"], data: template["data"], tags: template["tags"] ) endThis addition would make the method more robust and easier to debug if issues arise.
spec/core/terraform_config/generator_spec.rb (2)
10-17: LGTM! Consider using a constant for the error message.The new test case for unsupported template kinds is well-structured and correctly verifies the error handling. Good use of
:aggregate_failuresfor multiple assertions.Consider defining the error message as a constant in the
TerraformConfig::Generatorclass to ensure consistency across the codebase:# In TerraformConfig::Generator class UNSUPPORTED_KIND_ERROR = "Unsupported template kind - %s".freeze # In the test expect { generator.tf_config }.to raise_error(TerraformConfig::Generator::UNSUPPORTED_KIND_ERROR % template['kind']) expect { generator.filename }.to raise_error(TerraformConfig::Generator::UNSUPPORTED_KIND_ERROR % template['kind'])This approach would make it easier to maintain consistent error messages and update them if needed.
102-125: LGTM! Consider adding a test for the 'data' field.The new test case for the "secret" template kind is well-structured and correctly verifies the basic attributes of the secret. Good use of
:aggregate_failuresfor multiple assertions.To improve test coverage, consider adding an assertion to verify that the 'data' field is correctly handled by the
TerraformConfig::Secretinstance. You can add this assertion after line 120:expect(tf_config.data).to eq({ "key1" => "key1_value", "key2" => "key2_value2" })This will ensure that the secret data is correctly passed to and stored in the
TerraformConfig::Secretinstance.lib/core/terraform_config/secret.rb (3)
36-36: Raise a more specific exception for invalid secret typesRaising a generic
RuntimeErrormay make error handling less clear for users of this class. Consider raising a more specific exception, such asArgumentError, to provide clearer context about the nature of the error.Apply this diff to specify the exception type:
-raise "Invalid secret type given - #{type}" +raise ArgumentError, "Invalid secret type given - #{type}"
88-94: Handle optionalchainargument consistentlyIn the
tls_tfmethod, thechainargument is fetched with a default ofniland marked as optional:argument :chain, data.fetch(:chain, nil), optional: trueSince
fetchwith a default value will not raise an error if the key is missing, you can simplify it by usingdata[:chain]:Apply this diff for consistency and readability:
-argument :chain, data.fetch(:chain, nil), optional: true +argument :chain, data[:chain], optional: true
96-102: Ensure consistent handling of optional argumentsIn the
userpass_tfmethod, theencodingargument is optional. Similar to the previous comment, consider usingdata[:encoding]for consistency:Apply this diff:
-argument :encoding, data.fetch(:encoding, nil), optional: true +argument :encoding, data[:encoding], optional: true

1-1: Good use offrozen_string_literal: trueThe use of
frozen_string_literal: trueis a good practice. It helps improve performance and prevents accidental string mutations.
1-17: Overall, well-implemented extensions to the Hash classThe additions to the
Hashclass provide useful utility methods for key transformation. Bothsymbolize_keysandunderscore_keysare implemented with proper error handling, ensuring robustness.The suggestions provided earlier aim to improve:
- Readability of the
symbolize_keysmethod by using a block form for error handling.- Robustness of the
underscore_keysmethod by adding a dependency check.These changes will enhance the overall quality and maintainability of the code.
9-16: Effective implementation ofunderscore_keys, consider adding a dependency checkThe
underscore_keysmethod effectively converts keys to underscored format while preserving the original key type (string or symbol). The error handling is well-implemented.However, the method relies on the
underscoremethod, which is not part of Ruby's standard library. It's likely from ActiveSupport. Consider adding a check to ensure the required library is available:def underscore_keys raise "Required method 'underscore' not found. Ensure ActiveSupport is included." unless "".respond_to?(:underscore) transform_keys do |key| underscored = key.to_s.underscore key.is_a?(Symbol) ? underscored.to_sym : underscored rescue StandardError key end endThis addition will provide a clear error message if the required dependency is missing.
Let's verify the presence of the
underscoremethod in the codebase:spec/pathces/hash_spec.rb (1)

frozen_string_literalpragma andspec_helperrequirement. The RSpec structure is clear and follows best practices.lib/core/terraform_config/gvc.rb (1)
27-27: Improved readability with potential performance benefits. Verify method availability.The change from a custom
transform_keysblock to usingunderscore_keysandsymbolize_keysmethods improves code readability while maintaining the same functionality. This approach is likely more efficient, depending on the implementation of these methods.Please ensure that
underscore_keysandsymbolize_keysmethods are available in the project's context. They might be part of a custom extension or a library like ActiveSupport. Run the following script to verify the availability and usage of these methods:If these methods are custom implementations, ensure they are properly tested and documented.

1-44: Overall assessment of changesThe modifications to the
tf_valuemethod in theTerraformConfig::Dslmodule enhance its capability to handle multi-line strings in Terraform configurations. This improvement allows for more flexible and readable representation of complex string values.The changes are well-contained within the
tf_valuemethod and don't introduce breaking changes to the module's interface. The existing functionality for single-line strings and expressions is preserved, ensuring backward compatibility.While the implementation achieves its goal, there's room for further refinement as suggested in the previous comment. These refinements would make the method more flexible and robust, catering to various use cases and coding standards.
To ensure that these changes don't negatively impact other parts of the codebase, please run the following verification:

1-91: Summary: Successful implementation of secret template support.The changes to the
Generatorclass effectively implement support for the new "secret" template kind. The modifications are consistent with existing patterns and integrate well with the current structure. The newsecret_configmethod appropriately handles the creation ofTerraformConfig::Secretinstances.A few minor suggestions have been made for potential improvements:
- Consistent formatting in the
tf_configmethod.- Adding error handling in the
secret_configmethod.Overall, these changes enhance the functionality of the Terraform configuration generator by adding support for secret templates.

50-50: 🛠️ Refactor suggestionConsider a more flexible approach for template kind filtering
The addition of 'secret' to the allowed template kinds aligns with the PR objective of supporting secret templates. However, there are a few points to consider:
The TODO comment above this line suggests that this filtering is temporary. It would be beneficial to address this comment and implement a more permanent solution.
The current approach of explicitly listing allowed kinds might not be scalable if more template kinds are added in the future.
It's not clear what happens to templates that don't match these kinds. Are they silently skipped?
Consider refactoring this to use a more flexible approach. For example:
ALLOWED_TEMPLATE_KINDS = %w[gvc identity secret].freeze # ... next unless ALLOWED_TEMPLATE_KINDS.include?(template["kind"])This allows for easier management of allowed kinds and makes it simpler to add or remove kinds in the future.
For a long-term solution, consider implementing a strategy pattern where each template kind has its own handler. This would eliminate the need for this kind of filtering altogether and make it easier to add new template kinds in the future.
To ensure this change doesn't introduce any regressions, let's verify the usage of template kinds across the codebase:
This will help us understand if there are any other places in the code that might need to be updated to handle the new 'secret' template kind.
✅ Verification successful
Addition of 'secret' to allowed template kinds verified
The addition of 'secret' to the allowed template kinds aligns with the objective of supporting secret templates. However, please note the existing TODO comment indicates that this filtering is intended to be temporary and should be revisited once all template kinds are supported.

1-125: Overall, great additions to the test suite!The new test cases for unsupported template kinds and the "secret" template kind significantly improve the coverage of the
TerraformConfig::Generatorclass. These additions will help ensure the robustness of the generator when dealing with various template types.The structure of the tests is consistent with the existing ones, making the file easy to read and maintain. The use of
:aggregate_failuresin both new contexts is a good practice for cleaner test output.With the suggested minor improvements (using a constant for the error message and adding a test for the 'data' field in the secret context), this update will provide comprehensive coverage for the new functionality.

37-44: Excellent implementation of multi-line string handling!The changes to the
tf_valuemethod address the previous suggestions effectively:
- The heredoc delimiter is now configurable.
- The indentation for multi-line strings is customizable.
- Whitespace in multi-line strings is preserved.
These improvements enhance the flexibility and robustness of the Terraform configuration generation.
For improved code clarity, consider extracting the multi-line string handling into a separate private method:
def tf_value(value, heredoc_delimiter: "EOF", multiline_indent: 2) value = value.to_s if value.is_a?(Symbol) return value unless value.is_a?(String) return value if expression?(value) return "\"#{value}\"" unless value.include?("\n") format_multiline_string(value, heredoc_delimiter, multiline_indent) end private def format_multiline_string(value, delimiter, indent) "#{delimiter}\n#{value.indent(indent)}\n#{delimiter}" endThis refactoring would make the main method more concise and easier to read.
spec/pathces/hash_spec.rb (2)
17-23: LGTM: Consider adding a test for deeper nestingThis test case effectively demonstrates that only top-level keys are transformed. However, to ensure comprehensive coverage, consider adding a test case with deeper nesting to verify the behavior remains consistent at multiple levels.
Here's a suggested additional test:
it "does not transform keys in deeper nested levels" do deep_nested_hash = { "outerCamelCase" => { "innerCamelCase" => { "deeperCamelCase" => "value" } } } expect(deep_nested_hash.underscore_keys).to eq( "outer_camel_case" => { "innerCamelCase" => { "deeperCamelCase" => "value" } } ) end
1-73: Overall: Excellent test coverage with room for minor improvementsThis test suite for
Hash#underscore_keysis comprehensive and well-structured. It covers various scenarios including empty hashes, nested hashes, already underscored keys, keys with special characters and numbers, and both string and symbol keys. The tests are clear, concise, and isolate different cases effectively.To further enhance the test suite, consider the following suggestions:
- Add a test for deeper nesting levels, as mentioned earlier.
- Include a test case with a mix of string and symbol keys in the same hash.
- Consider adding a performance test for large hashes to ensure the method scales well.
These additions would make an already strong test suite even more robust.

56-65: Consider adding a comment explaining the use ofsendThe use of
sendto dynamically call methods is intentional and controlled in this context, as discussed in previous reviews. However, to improve code clarity and prevent future misunderstandings, consider adding a comment explaining whysendis used here and how it's kept safe.For example:
# Dynamic method call is safe here as the method names are strictly controlled # by the case statement and correspond to private methods defined in this class. send("#{type.underscore}_tf")This comment would help future maintainers understand the design decision quickly.

9-15: LGTM: Good coverage of edge caseThis test case appropriately checks the behavior of
underscore_keyswith an empty hash, which is an important edge case to consider.
25-31: LGTM: Good test for idempotenceThis test case effectively verifies that the
underscore_keysmethod is idempotent, ensuring that already underscored keys remain unchanged. This is an important property to maintain.
33-39: LGTM: Comprehensive edge case coverageThis test case effectively covers important edge cases by including keys with numbers and special characters. It ensures that the
underscore_keysmethod can handle these scenarios correctly, which is crucial for robust functionality.
41-55: LGTM: Thorough coverage of string key scenariosThese test cases provide comprehensive coverage for various string key formats, including camelCase, snake_case, and keys with multiple uppercase letters. The separate tests for each scenario allow for easy isolation of potential issues.
57-71: LGTM: Consistent coverage for symbol keysThese test cases mirror the string key tests, providing consistent coverage for symbol key formats. This parallel structure ensures that the
underscore_keysmethod behaves consistently regardless of whether the keys are strings or symbols.lib/core/terraform_config/secret.rb (2)
42-54: Well-structured data preparation and validationThe
prepare_dataandvalidate_required_data_keys!methods are well-implemented:
- The use of
tapinprepare_datais a clean Ruby idiom.- The validation logic in
validate_required_data_keys!is thorough and raises a clearArgumentErrorwhen required keys are missing.- The methods work together to ensure data consistency and completeness.
This approach enhances the robustness of the secret creation process. Good job!
1-132: Overall, well-implemented and flexible secret managementThis
Secretclass provides a comprehensive and flexible way to manage various types of secrets for Terraform configurations. Key strengths include:
- Clear structure and organization of code.
- Robust data preparation and validation.
- Flexible handling of different secret types.
- Good use of Ruby idioms and practices.
While there are opportunities for refactoring to reduce complexity and improve maintainability, the overall implementation is solid and well-thought-out. Great job on creating a versatile solution for secret management!
