Staticcheck

What Staticcheck is

Staticcheck is a free Go linter that applies static analysis to detect bugs and performance issues, recommend simpler code, and enforce style rules. More than 150 checks cover correctness, simplification, style, and quick fixes. The project emphasizes checks designed to produce few or no false positives, making Staticcheck suitable for continuous integration without spurious failures. It runs from the command line, in CI pipelines, and inside editors. Integration with gopls and most major Go editors lets it report problems and offer automatic fixes. Projects can control checks and individual behavior through TOML files named staticcheck.conf. A published GitHub Actions workflow runs it in CI. Installation options include go install, binary releases for common operating systems and CPU architectures, plus packages for Arch Linux, Debian, Fedora, Homebrew, MacPorts, NixOS, and Scoop; package-manager releases may lag. Each release supports the two Go versions most recent when that release was made. Staticcheck runs on Linux, macOS, and Windows and is presented for use alongside go vet during development or CI.
