Thanks for the PR! Would you mind fixing the linting errors? It looks like golangci-lint just wants usages of ioutil to be replaced with io or os. These are the offending usages:

structslop/structslop.go

Line 190 in 275afe0

if err := ioutil.WriteFile(fn, content, st.Mode()); err != nil {

structslop/structslop_test.go

Lines 37 to 54 in 275afe0

	tmpdir, err := ioutil.TempDir(dir, "structslop-test-apply-")
	if err != nil {
	t.Fatal(err)
	}
	defer os.RemoveAll(tmpdir)
	fn := filepath.Join(tmpdir, "p.go")
	src, _ := ioutil.ReadFile(filepath.Join(".", "testdata", "src", "struct", "p.go"))
	if err := ioutil.WriteFile(fn, src, 0644); err != nil {
	t.Fatal(err)
	}
	testdata := analysistest.TestData()
	_ = structslop.Analyzer.Flags.Set("apply", "true")
	defer func() {
	_ = structslop.Analyzer.Flags.Set("apply", "false")
	}()
	analysistest.Run(t, testdata, structslop.Analyzer, filepath.Base(tmpdir))
	got, _ := ioutil.ReadFile(fn)
	expected, _ := ioutil.ReadFile(filepath.Join(".", "testdata", "src", "struct", "p.go.golden"))
