brazilian-utils/dotnet

This system is a .NET 8 library, originally written in C\# and now rewritten in F\#, dedicated to validating and formatting Brazilian-specific identifiers and financial data. It provides comprehensive modules for checking documents such as CPF, CNPJ, CNH, and CEP, as well as financial instruments like Boletos and Pix payloads. The codebase includes extensive unit tests to ensure the correctness of these validation algorithms and formatting logic.

The BrazilianUtils library has been rewritten in F\# (replacing the previous C\# implementation), introducing a comprehensive suite of new validation and utility modules. This update adds support for validating and formatting Brazilian Area Codes, Bank codes (COMPE/ISPB), Bank Accounts (including Verhoeff algorithm for Nubank), Boleto lines, CAEPF, CBO, CEI, CEP (with ViaCEP integration), Civil Registry Certificates, CFOP, CNAE, and CNH (2022 format). It also includes a new CNO module and updates the package version to 2.4.0.

BrazilianUtils · high confidence

The Brazilian Utils library has been rewritten in F\#, replacing the previous C\# implementation. This migration is reflected in the solution file, which now references .fsproj files instead of .csproj, and includes a new .editorconfig for F\# formatting. Additionally, the project target framework has been updated to .NET 8, as noted in the changelog.

(repo-wide) · high confidence

Added comprehensive unit tests across the BrazilianUtils.Tests project for validating Brazilian identifiers and utilities, including Boletos, CEPs, CNHs, CNPJs, CPFs, IEs, Legal Process IDs, License Plates, NFe keys, Phones, PIS, Pix payloads, RENAVAMs, and Voter IDs. The tests cover valid/invalid inputs, formatting, generation, and specific regression fixes for edge cases such as CNPJ digit generation, CNH checksum remainder handling, and Pix payload mutual exclusivity.

BrazilianUtils.Tests · high confidence

The BrazilianUtils library and its test suite have been migrated from C\# to F\#, replacing the previous .NET Standard 2.0 and .NET Core 2.1 targets with .NET 8. This change updates the project structure to use .fsproj files, upgrades the test framework dependencies (xunit to 2.9.2, Microsoft.NET.Test.Sdk to 17.11.1), and sets the library version to 2.4.0.
