This allows a deeper lint-check of printf style functions, like: commands/instances.go:344:46: printf: github.com/arduino/arduino-cli/internal/i18n.Tr format %v reads arg #1, but call has 0 args (govet) s := status.Newf(codes.FailedPrecondition, i18n.Tr("Loading index file: %v"), err)
This commit fixes invalid calls to i18n.Tr.
1. Missing positional arguments, for example:
return fmt.Errorf(i18n.Tr("installing %[1]s tool: %[2]s"), tool, err)
in the above case the positional arguments must be part of the Tr call:
- return fmt.Errorf(i18n.Tr("installing %[1]s tool: %[2]s"), tool, err)
+ return fmt.Errorf(i18n.Tr("installing %[1]s tool: %[2]s", tool, err))
2. This also makes the fmt.Errorf call useless and it could be replaced by
the less expensive errors.New:
- return fmt.Errorf(i18n.Tr("installing %[1]s tool: %[2]s", tool, err))
+ return errors.New(i18n.Tr("installing %[1]s tool: %[2]s", tool, err))
but we have cases of useless calls even when the string is a constant,
for example:
- err := fmt.Errorf(i18n.Tr("no instance specified"))
+ err := errors.New(i18n.Tr("no instance specified"))
Unfortunately, this imperfection is not detected by the linter.
3. The "%w" directive is not supported directly in i18n.Tr, so we have
to wrap it around another fmt.Errorf:
- return nil, fmt.Errorf(i18n.Tr("reading library headers: %w"), err)
+ return nil, fmt.Errorf("%s: %w", i18n.Tr("reading library headers"), err)
