The following features and functionality are currently implemented:

• signature begin, end, version
• boolean, set of boolean
• char, widechar, custom char, set of custom char
• integers, custom int, set of custom int
• strings, codepage system and UTF8
• float, currency
• enum, custom enum range
• set of enum, set of custom enum range
• variant: integers, boolean, string, floats, currency
• method
• persistent
• component children, use SetParentComponent or optional Parent
• collection
• IInterfaceComponentReference
• with ancestor
• ancestor: change ComponentIndex -> call SetChildPos
• reference foreign root, reference foreign component
• create components before setting properties to avoid having to set references later
• inline component, csInline, call SetInline, inherited inline, inline on inherited
• TComponent.Left/Right via DesignInfo
• DefineProperties
• RegisterDefinePropertiesPas

TCompWriterPas is used in the implementation of the TCustomFormEditor class in the Lazarus IDE.
