    <p>Our <a href="http://www.semanticdesigns.com/Products/FrontEnds/CppFrontEnd.html" rel="nofollow">C++ Front End</a> is able to parse a variety of C++ dialects (ANSI, GCC, MSVS), automatically builds ASTs whose nodes are marked with precise source positions and are decorated with any nearby comment text, and builds a full symbol table. (EDIT Jan 2013: the C++ front end has been able to handle C++11 for quite awhile now).</p> <p>The C++ front end is built on top of our <a href="http://www.semanticdesigns.com/Products/DMS/DMSToolkit.html" rel="nofollow">DMS Software Reengineering Toolkit</a>, generalized compiler technology for program analysis and transformation, designed to support custom tool building. The C++ front end includes a preprocessor, in which the preprocessor directives can be expanded or not collectively or individually as appropriate for the task. It also includes full symbol construction with all the nasty Koenig lookup stuff.</p> <p>DMS accepts explicit language definitions (that's how it understands C++; there are also fron ends for C, C#, Java, COBOL, and variety of other languages). DMS provides general parsing, symbol table building, flow analysis machinery, procedural APIs for tree navigation/inspection/modification, source-to-source transformation, and AST-to-source text regeneration including the original comments, number radices, etc. All of these capabilities are available for use by the C++ Front End.</p> <p>DMS is also designed to handle the scale required for serious tasks. Often you need not just <em>one</em> compilation unit (which is what GCC will give you at best) but access to an entire set. DMS has been used to analyze/transform thousands of C++ compilation units, and literally tens of thousands of C compilation units (on a 25 million line application).</p> <p>"Easy to use library" is an oxymoron when it comes to program manipulation tools. The langauges themselves are complex (C++ being one of the most difficult and getting worse with C++0X) and that induces complexity in the nature of the questions you can ask and what the answers look like (e.g. "are there any template instantions that can modify local variable X in method Y in class C in any namespace N?"). The questions themselves are hard.</p> <p>What you want is a library with the <em>necessary</em> complexity to let you carry off your task. DMS has been under continuous development for the last 15 years, to provide that necessary complexity. If you want to do serious program processing, I claim you will need that information.</p> <p>As proof, DMS has been used to carry out massive automated reengineering of C++-based mission avionics software for Boeing. I don't believe there are any other tools that can do this. (Clang looks to be trying, but only for C++. YMMV).</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
