The Ada package is only an anchor or namespace for Ada's standard library. Most compilers will not allow you to add new packages to the Ada hierarchy and even if your compiler allows it you should not do so since all package names starting with Ada. are reserved for future extensions.

List of language defined child units

The following library units (packages and generic subprograms) are descendents of the package Ada.

(Ada 2005)
This package is available since Ada 2005.
(Ada 2012)
This package is available since Ada 2012.
(Ada 2022)
This package is available since Ada 2022.

A – C

Ada.Calendar.Arithmetic (Ada 2005)

Ada.Characters.Conversions (Ada 2005)

Ada.Containers.Bounded_Doubly_Linked_Lists (Ada 2012)

D – F

Ada.Directories.Hierarchical_File_Names (Ada 2012)

Ada.Dispatching.EDF (Ada 2005)

Ada.Execution_Time.Interrupts (Ada 2012)

G – R

Ada.Interrupts.Names

Ada.Numerics.Big_Numbers (Ada 2022)

W – Z

List of implementation defined child units

The Reference Manual allows compiler vendors to add extensions to the Standard Libraries. However, these extensions cannot be directly children of the package Ada, only grandchildren—for example Ada.Characters.Latin_9.

Currently, only the implementation defined library units of the GNAT compiler are listed here. You can help Wikibooks by adding implementation dependent packages of other compilers:

GNAT
Extended package implemented by GNAT.
ObjectAda
Extended package implemented by ObjectAda.
APEX
Extended package implemented by IBM/Rational APEX.

A – K

L – Q

R – Z

Nobody has written it yet — it is the source material at a new address, which is why search engines are asked to skip it and why no one earns from it. It is up for grabs: take it on, and it is yours to rewrite and to earn from.
