To systematically address and rectify issues related to error handling and parameter validation in the rendering tool, enhancing the tool's reliability and user interface.
Issues and Proposed Solutions
Invalid Input File Handling
Issue: Failure to properly notify users when an invalid input file is supplied.
Solution: Before processing, validate the input XML file's integrity and structure, providing a descriptive error message upon detection of invalid content, and halt execution.
Parameter Handling Deficiencies
Issues and Solutions:
No Parameters Supplied: Automatically display a detailed help message outlining all available parameters when the tool is run without arguments.
Empty World Parameter: Check for and report the absence of a value following the -w parameter.
Silent Parameter Misuse: Clarify the non-acceptance of values with the silent (-s) parameter and enforce this rule by issuing an error if a value is mistakenly provided.
Missing World Parameter: Ensure the tool offers comprehensive usage guidance when mandatory parameters like -w are omitted.
Interrupted Overwrite Selection: Handle interruption (e.g., Ctrl+C) gracefully during overwrite confirmation prompts without throwing exceptions.
Inaccurate Usage Help Message: Update the help (-h) command output to accurately reflect all command-line options, including -h, -i, -w, and -s, with clear descriptions.
Specific File Access and Overwrite Concerns
Issues and Solutions:
Overwrite Failure with Open Files: Detect and notify users when an attempt to overwrite existing files fails because they are open in another application, like Excel.
Silent Overwrite Conflicts: In silent mode, specifically handle cases where files cannot be silently overwritten due to being in use, informing the user of the issue.
Invalid World Path: Validate the provided world path for existence and write permissions before attempting file operations, issuing a clear warning if the path is invalid.
Enhanced Error Reporting
General Approach: For all errors, especially those resulting from invalid parameters or operational interruptions, ensure the tool provides clear, actionable feedback to the user and logs these incidents appropriately for troubleshooting.
Action Items
[ ] Implement upfront validation for the input XML file structure.
[ ] Enhance parameter validation logic to cover all cases of misuse or omission.
[ ] Revise the help message to fully document the tool's command-line interface.
[ ] Develop robust error handling for file access issues, particularly during overwrite operations.
[ ] Test each identified issue with corresponding fixes to ensure comprehensive coverage and solution effectiveness.
Goal
Through these improvements, aim to significantly elevate the user experience by making the rendering tool more intuitive, fault-tolerant, and informative, thereby minimizing user errors and frustration.
