lintero

Lintero is a generic term used to describe a static analysis tool that focuses on linting, i.e., checking source code for potential errors, style violations, and potential bugs. It is designed to help developers enforce coding standards and catch issues early in the development cycle. It is language-agnostic in some contexts, while in others it targets specific languages through configurable rule sets.

Features include a rule engine that can be extended with community or custom rules, support for multiple languages or ecosystems, integration with code editors and IDEs, integration with continuous integration pipelines, and a mechanism to autofix certain issues. Configuration is typically provided via a manifest file or configuration section that lists enabled rules and their severities.

Operation involves parsing source files to generate an abstract syntax tree or other semantic representation, applying a set of rules to detect issues, and reporting findings with location and severity. Many implementations classify issues by error, warning, or info, and may offer autofix capabilities or suggested corrections.

Use cases include enforcing consistent styling, catching common bugs (like undefined variables, unreachable code), optimizing code quality, and improving maintainability. In collaborative projects, lintero helps enforce shared guidelines across teams.

The term can also refer to specific projects named Lintero in different ecosystems; there is no single canonical tool universally recognized under that name. See also: Lint, Static code analysis, Code quality tools.
