README

honnef.co/go/tools fork with github.com imports

github.com/cabify/go-tools is a fork of github.com/dominikh/go-tools rewriting import paths to use github.com domain instead of honnef.co custom one which is frequently down and therefore unsuitable for using in automated builds.

honnef.co/go/tools/... is a collection of tools and libraries for working with Go code, including linters and static analysis.

These tools are supported by patrons on Patreon and sponsors. If you use these tools at your company, consider purchasing commercial support.

Tools

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.

Tool Description
gosimple Detects code that could be rewritten in a simpler way.
keyify Transforms an unkeyed struct literal into a keyed one.
rdeps Find all reverse dependencies of a set of packages
staticcheck Detects a myriad of bugs and inefficiencies in your code.
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.
unused Reports unused identifiers (types, functions, ...) in your code.
megacheck Run staticcheck, gosimple and unused in one go

Libraries

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. If you decide to use these libraries, please vendor them and expect regular backwards-incompatible changes.

Documentation

You can find more documentation on staticcheck.io.
