Summary of Changes
Hello @arvi18, 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!
This pull request refactors the handling of GitHub event data in main.py to improve robustness and error reporting. It introduces a dedicated function for loading event files, enhancing error handling for file operations and JSON parsing, and provides clearer console output.
Highlights
- Robust Event Loading: A new load_github_event function is introduced to encapsulate the logic for reading and parsing the GitHub event JSON file, including comprehensive error handling for FileNotFoundError, json.JSONDecodeError, and other exceptions.
- Improved Error Handling: The application now gracefully handles cases where the GITHUB_EVENT_PATH is not set or the event file cannot be read/parsed, exiting with a non-zero status code (sys.exit(1)) to indicate failure.
- Enhanced Logging: Console output messages have been updated with clearer language and emojis to provide better visual cues for success, warnings, and errors.

Code Review
This pull request refactors the GitHub event loading logic into a dedicated function, improving modularity and error handling. The changes also ensure that the script exits with a non-zero status code on critical errors, which is a good practice for CI/CD workflows. My feedback focuses on a standard convention for command-line scripts: directing error and warning messages to sys.stderr to separate them from standard output.

This function is well-structured for loading the event data. For better adherence to command-line tool conventions, error messages should be printed to standard error (sys.stderr) rather than standard output. This allows users to separate normal output from error logs. You can do this by adding the file=sys.stderr argument to your print calls within the except blocks.

Similar to the error handling in load_github_event, this warning and error message should also be directed to standard error (sys.stderr). This is a standard practice for command-line applications to distinguish between informational output and diagnostics.
| if not github_event_name: | |
| print("⚠️ GITHUB_EVENT_NAME not set.") | |
| else: | |
| print(f"📦 Received GitHub event: {github_event_name}") | |
| if not github_event_path: | |
| print("GITHUB_EVENT_PATH not set, cannot read event data.") | |
| return | |
| print("❌ GITHUB_EVENT_PATH not set. Cannot read event data.") | |
| sys.exit(1) | |

Missing Type Annotation
The function uses Any type which is too generic. This reduces type safety and prevents proper static type checking for the return value.

Inconsistent Error Handling
Inconsistent error handling between github_event_name and github_event_path. Missing event name only prints a warning while missing event path exits the program, creating unpredictable behavior.

| print("⚠️ GITHUB_EVENT_NAME not set.") | |
| else: | |
| print(f"📦 Received GitHub event: {github_event_name}") | |
| if not github_event_path: | |
| print("GITHUB_EVENT_PATH not set, cannot read event data.") | |
| return | |
| print("❌ GITHUB_EVENT_PATH not set. Cannot read event data.") | |
| sys.exit(1) | |
| if not github_event_name: | |

Missing Docstring
The load_github_event function lacks a docstring. This reduces code maintainability as other developers won't understand the function's purpose and behavior without reading the implementation.

Missing Newline
The file is missing a newline at the end, which is causing the SECTION 1 text to be appended to the code. This could cause syntax errors or unexpected behavior.
