errwrap
A Go tool that analyzes and fixes fmt.Errorf() calls to use the new %w error-wrapping verb directive.
What is errwrap?
errwrap is a Go command-line tool that analyzes Go source code to identify fmt.Errorf() calls that should use the %w error-wrapping verb directive introduced in Go 1.13. It helps developers migrate their error handling patterns to support proper error wrapping and inspection, and can automatically fix detected issues.
Go developers maintaining codebases that need to adopt Go 1.13+ error wrapping conventions, particularly those working on larger projects where manual updates would be tedious.
Developers choose errwrap because it automates a tedious but important code migration task, ensures consistent error wrapping patterns across codebases, and integrates seamlessly with existing Go tooling through the go/analysis framework.
