Staticcheck is a state of the art linter for the Go programming language. Using static analysis, it finds bugs and performance issues, offers simplifications, and enforces style rules.

Financial support by private and corporate sponsors guarantees the tool's continued development. Please become a sponsor if you or your company rely on Staticcheck.

You can find extensive documentation on Staticcheck on its website.

It is recommended that you run released versions of the tools. These releases can be found as git tags (e.g. 2022.1).

The easiest way of installing a release is by using go install, for example go install honnef.co/go/tools/cmd/staticcheck@2022.1. Alternatively, we also offer prebuilt binaries.

You can find more information about installation and releases in the documentation.

You can also run the master branch instead of a release. Note that while the master branch is usually stable, it may still contain new checks or backwards incompatible changes that break your build. By using the master branch you agree to become a beta tester.

All of the following tools can be found in the cmd/ directory. Each tool is accompanied by its own README, describing it in more detail.

In addition to the aforementioned tools, this repository contains the libraries necessary to implement these tools.

Unless otherwise noted, none of these libraries have stable APIs. Their main purpose is to aid the implementation of the tools. You'll have to expect semiregular backwards-incompatible changes if you decide to use these libraries.

Staticcheck can be compiled and run with the latest release of Go. It can analyze code targeting any version of Go upto the latest release.
