# Background

A static analysis is a function that inspects a package of Go code and
reports a set of diagnostics (typically mistakes in the code), and
perhaps produces other results as well, such as suggested refactorings
or other facts. An analysis that reports mistakes is informally called a
"checker". For example, the printf checker reports mistakes in
fmt.Printf format strings.

run 'go env -w <NAME>=<VALUE>'. Defaults changed using 'go env -w'
are recorded in a Go environment configuration file stored in the
per-user configuration directory, as reported by os.UserConfigDir.
The location of the configuration file can be changed by setting
the environment variable GOENV, and 'go env GOENV' prints the
effective location, but 'go env -w' cannot change the default location.
