Gopher Artwork

Goo is a reflection library written in Go, which provides an abstraction for built-in reflection api in GoLang. Thanks to the abstraction which is provided, it make reflection easier. Unlike built-in reflection api, it is easy to use and understand.

If you want to contribute to library or find a bug, please report.

Which projects uses

• Procyon Framework written in Go uses it during development, which is a Http Web Framework
