CAST Administrators

Summary: This page describes what you need to do if you have existing custom Universal Analyzer extensions (language packages) used with previous versions of CAST AIP and you want to use them with this release and any future release of CAST AIP.


CAST has made changes to the way in which Universal Analyzer extensions (language packages) are handled:

Each change is detailed below.

XML configuration file encoding

All XML files used in the extension must use the UTF-8 encoding as follows:

<?xml version="1.0" encoding="utf-8" ?>

The following files are involved:

Regular Expression formatting

You must ensure that any Regular Expressions you have defined in your extension's configuration files (for example to detect specific objects) are compatible with the new BOOST Regular Expression engine.You can find out more about this engine here: http://www.boost.org/doc/libs/release/libs/regex/doc/html/boost_regex/syntax/perl_syntax.html.

The following files are involved:


All braces ( { and } ) in regular expressions need to be escaped with a backslash ( \ ). For instance, if you want to match one or more letters, followed by one or more blanks, followed by an opening brace:

Note that inside character sets ( […] ) the backslash is not necessary. For instance "[A-Za-z$({]" is correct and will match any letter, or the dollar sign, or the opening parenthesis, or the opening brace.

Extended ASCII characters

You cannot specify extended ASCII characters with the "\x…" notation any longer. Use character classes instead. For instance, to match any alpha-numeric character, including accented letters:

Metamodel changes

If you have developed the metamodel for your custom Universal Analyzer extension using the Excel file provided by CAST, then you must ensure that the following line is removed from your existing XXXmetamodel.xml file:

<tree parent="EnlightenUniversalObjects" category="EnlightenTree"/>

Custom extensions created for use with CAST AIP 6.4.x

In custom extensions developed for CAST AIP 6.4.x, references to the stored procedure ADG_CENTRAL_RESULT_STD (in either the metric tree XML file injected by CAST Server Manager or in the Assessment Model PMX file) must be replaced by references to the stored procedure ADG_CENTRAL_RESULT_DIAG when adapting the extension for use with CAST AIP 7.0.x (or higher).

Testing your changes

CAST highly recommends that you install a "test" CAST environment (i.e. all CAST schemas) to check that the changes you have made to the extension files are:

Once the extension has been tested and you are happy with the results, you can then apply it to your "production" CAST environment, either as part of a migration process to the current version of CAST AIP or by installing the extension from scratch in the current version of CAST AIP.
