The Rationale for Ada 2012
provides an overview of new Ada 2012 features, examples of their use,
compatibility with Ada 95 and 2005, and more. It was written by John Barnes, and was
sponsored in part by the Ada Resource Association
This is an unofficial description of the language; refer to the Ada 2012
standard for detailed language rules.
The Rationale is available on-line in HTML
on-line browsing and PDF
Note that the HTML version is slightly different than the PDF, as it includes a
Search function, and of course hotlinks.
This edition of the Rationale combines the all of the chapters
of the Rationale into a single document, fixes a number of errors, adds an index,
and adds discussion of various details of Ada 2012 that were changed since the original
publication of these chapters in the
Ada User Journal.
This version is substantially the same as the version published by Springer as LNCS 8338,
other than that the errata have been applied to the HTML version.
