I d like to, but when I write,
// Load returns the list of partition found and their properties.
func (l *LinuxLoader) Load() ([]*Properties, error) {
//-
ret := []*Properties{}
if temp, err := runDf(); err != nil {
return ret, err
}
ret = PropertiesList(ret).Append(PropertiesList(temp))
...
# github.com/mh-cbon/disksinfo/diskinfo
/tmp/go-build658543611/github.com/mh-cbon/disksinfo/diskinfo/_test/_obj_test/linux.go:25:
undefined: temp
FAIL github.com/mh-cbon/disksinfo/diskinfo [build failed]
:X
Otherwise i have to work with shadowed variable.
