Biome vs HLint

Biome is a toolchain for maintaining the health of web projects. It formats JavaScript, TypeScript, JSX, TSX, JSON, HTML, CSS, and GraphQL, and provides lint rules for JavaScript, TypeScript, JSX, CSS, and GraphQL. Linting can report diagnostics and apply safe fixes. Its check command can format files, lint them, and organize imports in one run. Biome is distributed as a standalone executable, so it does not require Node.js. Installation instructions cover npm, pnpm, bun, deno, and yarn. First-party editor extensions are available for VS Code, IntelliJ, and Zed; community extensions include Vim, Neovim, and Sublime Text. The getting-started guide links to CI integrations for GitHub Actions and GitLab CI. Biome describes itself as open source and lists MIT or Apache 2.0 licensing. The open-source toolchain is free. Contributors may offer commercial support, but requests depend on their availability.

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.
