func ServicePackageShadowNames ¶

func ServicePackageShadowNames(t testing.TB, dir, genpkg, marker string) []string

ServicePackageShadowNames returns the identifiers that the generated Go files below dir declare where a service package imported under the same name would not compile, in the packages that import a service or views package, that is a package whose import path is genpkg/<name> or genpkg/<name>/views:

• the package-level declarations, which conflict with the import;
• the receivers, parameters, results and locals in scope where a service or views package is used, which would hide it;
• in the files that do not import a service or views package, the receivers, parameters, results and locals that are the operand of a selector, such as ws in ws.Close(): a generated file keeps an import when a selector of its name remains, so the file would keep the service package import and leave it unused.

It skips the service and views packages themselves. The result is sorted. It omits struct field names, names with upper case letters, which no generated package name has, and every name that contains marker, so that a test design can mark the names it gives to generated code.
