To address and improve upon several identified issues regarding error handling and parameter validation in the placing tool, ensuring a more robust, user-friendly experience.
Issues Identified and Proposed Solutions
Handling Invalid Input Files
Issue: The tool does not correctly handle invalid input files, resulting in uninformative errors when content is missing or malformed.
Solution: Implement validation to check the input file's structure and content before processing. On detection of invalid content, provide a clear error message to the user and exit without proceeding.
No Parameters Supplied
Issue: Running the tool without any parameters does not yield a helpful message, leading to potential confusion about its usage.
Solution: Enhance the tool to detect when no parameters are supplied and respond by printing an informative help message detailing available commands and their usage.
Empty Output Parameter
Issue: The tool reacts incorrectly when the output parameter is supplied without a value.
Solution: Validate that the output parameter is followed by a valid file path. If not, display a clear message indicating the missing value and halt execution.
Inaccurate Usage Help Message
Issue: The help message (-h) does not accurately list or describe all available command-line options.
Solution: Update the help message to accurately reflect all available parameters (-h, -i, -o, -l, -m) and provide concise descriptions of their purposes and expected values.
Missing Layout Parameter Value
Issue: Omitting a value for the layout parameter (-l) does not trigger an appropriate warning.
Solution: Implement checks to ensure the layout parameter is accompanied by a valid value. Inform the user of the missing value with a clear message and stop the process.
Map Parameter Misuse
Issue: The tool does not correctly handle the misuse of the map parameter (-m) when a value is incorrectly provided.
Solution: Clarify in the documentation and error messages that the map parameter does not accept any values. Validate parameter usage and provide feedback if misused.
Invalid Output File Path
Issue: Specifying an invalid path for the output file does not result in user-friendly error handling.
Solution: Before attempting file creation, validate the output file path for feasibility. Notify the user with a clear and actionable error message if the path is found to be invalid.
