ERROR: Failed building wheel for Levenshtein Failed to build Levenshtein error: failed-wheel-build-for-install × Failed to build installable wheels for some pyproject.toml based projects ╰─> Levenshtein ERROR: Failed to install required packages cpanel webmail Set up email on application tool PDF Auto MATCHING LOGIC: EmployeeID, FirstName, MiddleName, LastName NAME-BASED MATCHING If Employee ID is not found in the filename, implement a controlled secondary matching method based on employee name. Example: PDF: ``` Abel Harry Anthony.pdf ``` CSV: ``` 10152 | Abel | Harry | Anthony | abel@example.com ``` The application should identify: ``` Abel Harry Anthony ``` and match it with the CSV record. The matching logic can be changed so the application uses any 3 of the 4 CSV fields: * `ID` * `First Name` * `Middle Name` * `Last Name` Input PDF: 10004_Vihang_Wani_SalarySlip_March_2026.pdf no need to rename the pdf file once it's attached also show dashboard me all attachments before sending email can be built as a Windows desktop application that: 1. Imports an employee CSV. 2. Lets you select a folder containing hundreds/thousands of PDFs. 3. Extracts the Employee ID from each filename. 4. Finds the matching employee in the CSV. 5. Renames the PDF according to a defined format. 6. Shows success, unmatched, duplicate, and error reports. 7. Provides a one-click Windows build that produces a `.exe`. For your example:Input: SumitShyamraoTunkikar_0020063_Aug_2026.pdf CSV: 20063 | Sumit | Shyamrao | Tunkikar Output: 20063_Sumit_Shyamrao_Tunkikar.pdf Or Input: Abel Harry Anthony.pdf CSV: 10152 | Abel | Harry | Anthony Output:10152_Abel_Harry_Anthony.pdf Or Input: AbhishekYadav_0020311_Aug_2026.pdf CSV: 20311 | Abhishek | Yadav Output:20311_Abhishek_Yadav.pdf SAFETY Original PDFs are preserved by default. The output is written to a separate folder. Add Naming Templates: Configure rename patterns: add Placeholders: Define how renamed pdf should look example: Pattern SalarySlip Or SalarySlip_ Live preview 20311_Abhishek_Yadav_SalarySlip_August_2026.pdf the specification to: The matching logic can be changed so the application uses any 3 of the 4 CSV fields: * `ID + First Name + Middle Name + Surname` * `ID + First Name + Surname` * `First Name + Middle Name + Surname` when no ID is present * Handle concatenated names such as `SumitShyamraoTunkikar` * Handle spaced names such as `Abel Harry Anthony` * Normalize leading-zero IDs: `0020063` → `20063` * Preserve the original PDFs * Never overwrite an existing output PDF * Separate Input and Output folders * Add configurable naming templates: * `` * `` * `` * `` * ` I will select month` * ` I will select year` * Extract `Month` and `Year` from the original filename where available * Provide a live preview * Provide a Preview/Review table before processing * Export unmatched/duplicate/error reports * Include Undo for the current output run Match method: uses any 3 of the 4 CSV must
