The advanced Go linter

Staticcheck is a state of the art linter for the Go programminglanguage. 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.

Documentation

You can find extensive documentation on Staticcheck on its website.

Installation

Releases

It is recommended that you run released versions of the tools. Thesereleases can be found as git tags (e.g. 2019.1) as well as prebuiltbinaries in the releases tab.

The easiest way of using the releases from source is to use a Gopackage manager such as Godep or Go modules. Alternatively you can usea combination of git clone -b and go get to check out theappropriate tag and download its dependencies.

Master

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

Tools

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

Tool	Description
keyify	Transforms an unkeyed struct literal into a keyed one.
staticcheck	Go static analysis, detecting bugs, performance issues, and much more.
structlayout	Displays the layout (field sizes and padding) of structs.
structlayout-optimize	Reorders struct fields to minimize the amount of padding.
structlayout-pretty	Formats the output of structlayout with ASCII art.

Libraries

In addition to the aforementioned tools, this repository contains thelibraries 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. If youdecide to use these libraries, please vendor them and expect regularbackwards-incompatible changes.
