Cppcheck vs HLint

Cppcheck is a static analysis tool for C and C++ code that detects bugs, undefined behavior, and dangerous coding constructs. It can analyze non-standard syntax commonly found in embedded projects. The tool fully supports C++11, C++14, and C++17, with partial support for C++20, and lists integrations with Visual Studio, VSCode, Keil, Eclipse, CLion, Qt Creator, and C++ Builder. Its Soundy mode is intended to help find hard-to-find bugs discovered during testing. The free Open-source plan provides core static analysis. Premium adds checks for safety and security standards, with compliance reports for supported standards; the maker describes Premium as TÜV SÜD certified for safety-critical development. A three-week free trial is offered without a credit card or commitment. Individual licensing excludes CI environments, virtual machines, and containers, while Enterprise supports those environments and air-gapped use. Project requires at least five users and one Git repository. Paid plan prices are available by tailored quotation.

HLint is free software for analyzing Haskell source and suggesting possible improvements. It can point out alternative functions, simpler expressions, and redundant code. Every hint identifies the file and line, gives a severity and description, shows the code found, and proposes a replacement. Projects can configure behavior in a .hlint.yaml file, adding custom hints or ignoring selected suggestions. The --refactor flag applies some recommendations and requires the refactor executable from the apply-refact package on PATH. The --report flag creates an interactive HTML findings report. HLint runs on Linux, macOS, and Windows, with listed integrations including editor plugins, Haskell Language Server, ghc-mod, Intero, a GHC source plugin, Code Climate, and GitHub Actions. It analyzes one module at a time without type or scope knowledge. Version 3.10 is listed as released February 2, 2024. It is distributed under a BSD-style license.
