Package shadow
Package shadow defines an Analyzer that checks for shadowed variables.
Constants
const Doc = `check for possible unintended shadowing of variables
This analyzer check for shadowed variables.
A shadowed variable is a variable declared in an inner scope
with the same name and type as a variable in an outer scope,
and where the outer variable is mentioned after the inner one
is declared.
(This definition can be refined; the module generates too many
false positives and is not yet enabled by default.)
For example:
func BadRead(f *os.File, buf []byte) error {
var err error
for {
n, err := f.Read(buf) // shadows the function variable 'err'
if err != nil {
break // causes return of wrong value
}
foo(buf)
}
return err
}
