^title Core Library ^category core

Because Wren is designed for embedding in applications, its core library is minimal and is focused on working with objects within Wren. For stuff like file IO, graphics, etc., it is up to the host application to provide interfaces for this.

All Wren source files automatically have access to the following classes:

• Bool
• Class
• Fiber
• Fn
• List
• Map
• Null
• Num
• Object
• Range
• Sequence
• String
• IO
