version 1.16r11 of June 5th, 2014
AdaControl is a free (GMGPL) tool that detects the use of various kinds of constructs in Ada programs. Its first goal is to control proper usage of style or programming rules, but it can also be used as a powerful tool to search for use (or non-use) of various forms of programming styles or design patterns. Searched elements range from very simple, like the occurrence of certaine entities, declarations, or statements, to very sophisticated, like verifying that certain programming patterns are being obeyed..
Which elements or constructs are searched is defined by a set of rules; the following table gives a short summary of rules currently checked by AdaControl. The number in parentheses after the rule name gives the number of subrules, if any. Considering all possible rules and subrules, this makes 513 tests that can be performed currently by AdaControl!

For more details on these rules, or on the use of AdaControl in general, please refer to the user guide below.
AdaControl is a command line tool, but it has been fully integrated into AdaCore's GPS environment. From GPS, you can run AdaControl, fix the violations, or edit the rules file with just a few clicks.
But AdaControl is more than a set of coding rules: it is a complete environment, designed to be easily extended. If your favorite rule is not provided, you can add it yourself! And of course, we will continue to extend the number of rules in the future. If you want to look into how this is possible, please refer to the AdaControl programmer guide.
Initial development of AdaControl was sponsored by Eurocontrol. Some rules were sponsored by BelgoControl, Ansaldo-STS (prev. CSEE-Transport) and SAGEM-DS. It is a mature tool, routinely used to check Ada codes at Eurocontrol (Brussels, more than 1_100_000 SLOC, Maastricht), BelgoControl, Ansaldo-STS, Faiveley, SAGEM-DS (level DO178B/A)... It has also been run against all executable tests from the ACATS.
AdaControl is an ASIS application.
AdaControl is a free tool under GMGPL license. Nonetheless, it is a commercial product from Adalog, for which we offer a maintenance contract. We offer also services for the development of rules for your specific needs, or more generally assistance for the definition and usage of programming rules. For information, please contact email@example.com.
AdaControl, like any ASIS application, can run only if compiled with the exact same version of the compiler that it uses itself when executing. It is therefore provided as executable only for GNAT GPL/2014 (Windows and Linux); for use with any other version of GNAT, please download the source version and recompile (which is quite easy to do, provided ASIS has been installed). It has been tested only with GNAT, but should be easily portable to any other compiler that provides an ASIS interface.
incompatibility was introduced in the
ASIS interface for Ada 2005/2012, which was necessary to properly
handle some of the new features. The source distribution of
AdaControl requires at least GnatPro-7.2.0 or GnatGPL 2013. If you want
to use an earlier version of Gnat, please dowload a source version from
SourceForge (cf. below),
using branch "master-old_gnat" for
versions up to GnatPro-7.0.x and GnatGPL2011, and branch "GPL2012'' for
The ZIP or TGZ versions allow you to install AdaControl as you please; under Windows, the installers install everything automatically - provided the <GNAT>\bin directory is on your execution path.
Windows Gnat GPL 2014
Linux Gnat GPL 2014
FreeBSD users: you can find a port of AdaControl to FreeBSD here.
The current development version (unstable) is available (under GIT)
You can also find there intermediate versions between official releases
that may be appropriate to certain versions of Gnat and even provide you own rating of
