history

Project history and usage

errcheck is a Go static-analysis command that reports error-valued results which are neither assigned nor explicitly discarded.

Project history

errcheck is maintained in the kisielk/errcheck repository as a focused static-analysis command for detecting unchecked Go error returns. Upstream also exposes an experimental Analyzer for integration with the go/analysis API.

Adoption history

errcheck became a familiar component of Go static-analysis workflows and is distributed through Go installation tooling as well as system package managers such as Homebrew and Nix, as recorded in source_facts.package-manager.

How it is used

Users run `errcheck` against one or more Go package patterns, commonly `./...`. Optional checks cover blank-identifier assignments and type assertions, while `-exclude` accepts an explicitly selected exclusions file. Because upstream documents no fixed default configuration path, the config-file-location is null.

Why package nerds care

The tool captures a characteristic Go concern: returned errors are ordinary values and may be accidentally discarded. Package enthusiasts value errcheck as a focused Unix-style checker and as an early, recognizable member of the broader Go linting ecosystem.

Timeline

Current project: Distributed as a Go command and an experimental go/analysis Analyzer.

The official README points users seeking deeper analysis toward Staticcheck. errcheck is also commonly encountered through multi-linter runners, although its standalone command remains useful.
