📝 Walkthrough

Walkthrough

This pull request refines both the documentation and the implementation of the check-redirects and fix-redirects scripts. The documentation now clearly explains that the check-redirects script identifies links pointing to old URLs based on data in the _redirects file, and that the fix-redirects script updates links—both in Markdown and HTML—to the new destinations. Terminology has been updated throughout, replacing "broken links" with "outdated links" and "files" with "pages". In the TypeScript files, error handling has been improved with try-catch blocks during file and directory operations, variable names have been adjusted for clarity (e.g., renaming updates to fixed), and the process now explicitly flags files that were changed before writing updates. Additional validations ensure that required files and directories exist, making the scripts more robust.

91-92: Added helpful troubleshooting information.

The added points about no outdated links being found and the script's limitation regarding destination URL verification provide valuable troubleshooting information for users.

You might want to ensure the list formatting is consistent by adding a space after the asterisk, as with other list items in the document:

-*   No outdated links found: Verify `_redirects` entries are correct or all links might already be updated.
-*   Links still broken after fixing: The script only updates links based on the `_redirects` file; it doesn't check if the destination URLs actually exist.
+*   No outdated links found: Verify `_redirects` entries are correct or all links might already be updated.
+*   Links still broken after fixing: The script only updates links based on the `_redirects` file; it doesn't check if the destination URLs actually exist.

1-2: Improved script identification and clarity!

Adding a shebang line and descriptive comment enhances script identification and usability, allowing direct execution and clarifying the file's purpose.


18-21: Improved interface formatting.

The reformatting of the Redirect interface improves code readability while maintaining the same functionality.


23-27: Improved interface formatting.

The reformatting of the Summary interface improves code readability while maintaining the same functionality.


30-30: Better terminology in warning messages.

Changing "broken link" to "outdated link" in the warning message is more accurate, as these links aren't broken but pointing to old URLs that have redirects.


33-46: Enhanced error handling in getRedirects function.

Adding try-catch error handling for file operations is an excellent improvement. This prevents the script from crashing when the redirects file can't be read and provides a meaningful error message.


48-67: Enhanced error handling in findMdxFiles function.

The addition of try-catch error handling for directory operations is a valuable improvement. This ensures the script continues execution even if a directory can't be accessed, logging the error instead of crashing.


88-103: Enhanced error handling in checkFile function.

Adding try-catch error handling for file operations in the checkFile function improves robustness. This ensures that errors during file checking are properly logged without stopping the entire process.


107-110: Improved summary output terminology.

Changing "files" to "pages" and "broken links" to "outdated links" in the summary output provides more accurate and consistent terminology throughout the application.


122-138: Added essential directory and file existence checks.

Adding explicit checks for the existence of the root directory and redirects file before proceeding is an excellent improvement. This prevents cryptic errors later in the process and provides clear error messages about missing prerequisites.


151-155: Improved error counting logic.

The modification to count files with errors rather than total warnings is a better approach. This provides a more meaningful summary by focusing on the number of pages that need attention rather than the total number of individual links.


171-175: Enhanced error handling for script execution.

Adding explicit script execution with proper error handling ensures that any uncaught errors during the main process execution are properly logged and result in an appropriate exit code.

9-9: Better terminology in section title.

Changing "broken links" to "outdated links" in the section title is more accurate and consistent with the actual functionality of the script.


14-15: Helpful addition of alternative command.

Adding the alternative command (pnpm lint) is useful for users who might be more familiar with the lint command for checking issues.


18-26: Excellent detailed explanation of check-redirects functionality.

This comprehensive explanation of what the check-redirects script does and doesn't do is very valuable. It clearly outlines the script's purpose and limitations, helping users understand exactly what to expect.


35-35: Updated example output for consistency.

The example output has been updated to use "Pages with outdated links" instead of referring to broken links, maintaining terminology consistency.


39-39: Better terminology in section title.

Changing "Fixing broken links" to "Fixing outdated links" in the section title is more accurate and consistent with the actual functionality of the script.


44-45: Helpful addition of alternative command.

Adding the alternative command (pnpm fix) is useful for users who might prefer a shorter command to fix issues.


48-58: Excellent detailed explanation of fix-redirects functionality.

This comprehensive explanation of what the fix-redirects script does is very valuable. It clearly outlines the script's capabilities, including handling both Markdown and HTML links, saving modified files, and reporting changes.


63-68: Updated example output for clarity and consistency.

The example output has been updated to use "Pages fixed" and "Pages unchanged" terminology, which better reflects what the script does and maintains consistency with the script's actual output.

1-2: Improved script identification and clarity!

Adding a shebang line and descriptive comment enhances script identification and usability, allowing direct execution and clarifying the file's purpose.


9-9: Better variable naming for clarity.

Renaming the variable from updates to fixed is a good change that better reflects the purpose of the array - to track fixed links rather than generic updates.


26-26: Improved terminology in Summary interface.

Changing skipped to unchanged in the Summary interface is more descriptive and accurately represents files that didn't need modifications, rather than suggesting they were intentionally skipped.


29-42: Enhanced error handling in getRedirects function.

Adding try-catch error handling for file operations is an excellent improvement. This prevents the script from crashing when the redirects file can't be read and provides a meaningful error message.


47-60: Enhanced error handling in findMdxFiles function.

The addition of try-catch error handling for directory operations is a valuable improvement. This ensures the script continues execution even if a directory can't be accessed, logging the error instead of crashing.


65-100: Significantly improved fixFile function with better error handling and safety checks.

The enhancements to the fixFile function include:

  1. Proper error handling for file operations
  2. Addition of a fileChanged flag to accurately track modifications
  3. Proper escaping of special characters in regex patterns to prevent potential regex errors
  4. Clear tracking of which files were modified before writing changes

These changes make the function more robust and reliable.


105-108: Improved summary output terminology.

Changing "files" to "pages" and "skipped" to "unchanged" in the summary output provides more accurate and consistent terminology throughout the application.


114-114: Improved field naming for consistency.

Changing the field name from skipped to unchanged ensures consistency with the interface definition.


121-135: Added essential directory and file existence checks.

Adding explicit checks for the existence of the root directory and redirects file before proceeding is an excellent improvement. This prevents cryptic errors later in the process and provides clear error messages about missing prerequisites.


138-142: Added informative logging.

The added log messages about the number of redirects loaded and MDX files found provide better visibility into the script's operations, which is helpful for both users and debugging.


154-159: Improved output message clarity.

Changing "fixed broken links" to "fixed outdated links" in the output message is more accurate and consistent with the terminology used throughout the application.


168-168: Added clarifying comment.

Adding a comment for script execution enhances code readability and maintainability.
