In their own words
HLint
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.
