# Test that go fix skips fixes to non-main and/or vendored packages.
# (It uses the interface{} -> any modernizer.)

# Create vendor tree programmatically to avoid
# having to hardcode sums in this txtar archive.
go mod vendor

# Show fixes on two packages, one in the main module
# and one in a vendored dependency.
# Only the main one (a) is shown.
go fix -diff example.com/a example.com/b
stdout 'a[/\\]a.go'
stdout '\-var _ interface\{\}'
stdout '\+var _ any'
! stdout 'b[/\\]b.go'

# Apply fixes to the same two packages.
# Only the main module was modified.
