Golang ArrayNameFromLength Examples

Example #1

File: main.go Project: sbinet/go-clang-gen

func prepareStructMembers(s *gen.Struct) {
	for _, m := range s.Members {
		if (strings.HasPrefix(m.CName, "has") || strings.HasPrefix(m.CName, "is")) && m.Type.GoName == gen.GoInt16 {
			m.Type.GoName = gen.GoBool
		}

		// If this is an array length parameter we need to find its partner
		maCName := gen.ArrayNameFromLength(m.CName)

		if maCName != "" {
			for _, ma := range s.Members {
				if strings.ToLower(ma.CName) == strings.ToLower(maCName) {
					m.Type.LengthOfSlice = ma.CName
					ma.Type.IsSlice = true
					ma.Type.LengthOfSlice = m.CName // TODO wrong usage but needed for the getter generation... maybe refactor this LengthOfSlice alltogether? https://github.com/go-clang/gen/issues/49

					break
				}
			}
		}
	}
}
