Hello @eapl-gemugami, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
Summary of Changes
This pull request refactors the documentai_quickstart sample to align with the latest style guide. The changes include moving the sample code inside a function, rewriting comments, replacing calls to documentai with documentai_v1 for clarity, adding type hints, and replacing stderr/out checks with assertions on returned objects. The test file was also updated to reflect these changes.
Highlights
- Refactor: The sample code is now encapsulated within a function to improve readability and ease of execution.
- Version Specificity: Replaced generic
documentaiimport withdocumentai_v1to explicitly denote the version being used. - Type Hinting: Added type hints to the function signature and variables for better code clarity and maintainability.
- Test Improvement: Replaced stdout/stderr checks in tests with direct assertions on the returned objects for more robust testing.

Code Review
The pull request refactors the 'documentai_quickstart' sample to align with the latest style guide, improving readability and maintainability. The changes include moving the sample inside a function, rewriting comments, using 'documentai_v1' for clarity, adding type hints, and replacing stderr/out checks with object assertions. Overall, the changes are well-structured and enhance the sample's quality.
Summary of Findings
- Type Hinting: The
quickstartfunction'sprocessor_display_nameparameter lacks a type hint, which should be added for clarity and to ensure type safety. - Variable Naming: The test file uses uppercase variable names (e.g.,
LOCATION,PROJECT_ID), which is generally reserved for constants. Consider using lowercase names for better readability and adherence to common Python conventions.
Merge Readiness
The pull request is well-structured and addresses the stated goals of refactoring the sample for better readability and style guide adherence. However, addressing the missing type hint and variable naming conventions would further improve the code quality. I am unable to directly approve this pull request, and recommend that others review and approve this code before merging.
