Predefined Language Libraries

Ada's built-in library is provided by three root library units: Ada, Interfaces, and System; other library units are children of these. The library is quite extensive and well-structured. These chapters too are more reference like. Most specifications included in them have been obtained from the reznikmm/adalib repository.

The package Standard contains all predefined identifiers in the language.

• Standard
• Ada
• Interfaces
• System

Ada 83 had a much smaller library and did not yet have this library structure. These root libraries were introduced in Ada 95 to inhibit a name pollution. To preserve compatibility, there exist renamings of all Ada 83 library units XXX as Ada.XXX respectively System.XXX; see RM J.1: Renamings of Library Units (Annotated). Contrary to the names in the root hierarchies, the original Ada 83 names XXX are not protected – they may be reused for user-defined library units.

Implementation-Defined Language Libraries

Every Ada implementation has as an extension of the predefined Ada library. One example is the library provided by the GNAT implementation.

• GNAT

Other Language Libraries

Other libraries which are not part of the standard but freely available.

• Multi Purpose
• Container Libraries
• GUI Libraries
• Distributed Objects
• Database
• Web Programming
