In simple English
This tool inspects your source code files and counts how many paths and decisions exist inside your functions. It helps you find messy parts of your project that might break later. You run it from your command line and it gives you a report. It costs nothing to use and runs locally on your machine. You need Python installed on your computer to run it.
What it is
Lizard is an extensible cyclomatic complexity analyser (a tool that counts the number of linearly independent paths through a program's source code) that supports many programming languages. It parses files directly without needing header files or package imports set up.
What it is good for
Solo builders want this to spot overly complicated functions before they become bugs, and to enforce quality checks in their projects.
- Works with dozens of programming languages like Python, JavaScript, C++, and Go.
- Does not require you to configure complex compiler header files or package imports.
- Can detect duplicate code blocks across your project.
- Requires Python 3.8 or above installed on your computer.
- Fails or misinterprets code when given syntactically incorrect source files.
- Custom licence terms require careful checking for commercial redistribution.
