プロジェクトの歴史

The terryyin/lizard repository was created on GitHub in June 2012. The README describes the tool as an extensible cyclomatic complexity analyzer for many programming languages, with an emphasis on scanning C/C++ without needing complete header search paths and Java without resolving all imports.

Over time the tool expanded beyond basic cyclomatic complexity counts into duplicate-code detection and other static-code metrics. Its language list in the README spans C/C++, Java, Python, JavaScript/TypeScript, Go, Rust, Swift, Solidity, Zig, and other languages.

採用の歴史

The README documents both direct script usage and installation through pip, which made Lizard convenient for CI jobs and local quality gates before language-specific static-analysis suites were always present in package-manager workflows.

Homebrew packaging under lizard-analyzer gives macOS users a CLI install path while avoiding the formula-name collision with the unrelated lizard compressor.

使われ方

Lizard is commonly used as a lightweight metric pass over source trees: run lizard on a path, optionally select languages, exclude paths, and fail builds when complexity or parameter-count thresholds are exceeded.

Because it intentionally measures how complex code looks rather than trying to fully compile or semantically resolve a project, it fits quick scans, pre-commit checks, and repository audits where low setup cost matters.

パッケージ好きにとっての重要性

The formula is a small example of package-manager disambiguation: the upstream project, command name, and common Python package name are lizard, but Homebrew has to call the formula lizard-analyzer because brew:lizard is already the compression tool.

It also shows how scripting-language tools enter Unix package managers even when pip installation is available, because packaging the CLI gives users a repeatable system-level binary without managing a Python environment by hand.

タイムライン

• 2012: terryyin/lizard repository created on GitHub.
• 2026: GitHub releases 1.20.0 and 1.23.0 were published for the analyzer.
• 2026: Homebrew formula lizard-analyzer identified the executable as lizard and the package as an extensible cyclomatic complexity analyzer.

Related projects

• The package sits near linters, static analyzers, and code-metric tools such as cloc, radon, cppcheck, and language-specific complexity plugins.
• It is unrelated to brew:lizard, the compression utility packaged in the same batch.
