    <p>I am about to starting to work on a project which involves refactoring and modifying existing code which is in c &amp; c++. The code is a bloated one and is in huge volume. Of course since the code needs to be modified, an understanding of the code has to be developed and in a very short span of time since we have some pretty time pressed project schedule. Can anyone please suggest any open source tools which will help in achieving the above. In short what I am looking for is tool which can:</p> <ol> <li>Reverse engineering tools which will help understand the design.</li> <li>Sequence generator tools which will help draw sequences at run time(Most probably we will be able to run the code, but not in the initial stages at least) or through code examination.</li> <li>Good code browsing tools to study the existing code base.</li> <li>Suitable tool which can auto refactor code with minimal efforts.</li> </ol> <p>Please do tell me about any experiences,preferences or favorites worth looknig out for.</p> <p>[EDIT] Came up with a list of tools to help in above. Here's the list:</p> <ol> <li><p><a href="http://www.graphviz.org/" rel="noreferrer">Graphviz</a> &amp; <a href="http://www.stack.nl/~dimitri/doxygen/" rel="noreferrer">Doxygen</a><br> Generate UML class diagrams from existing code base</p></li> <li><p><a href="http://www.pragsoft.com/prod_umls.html" rel="noreferrer" title="Umlstudio">UMLStudio</a><br> Creating an object model for your OO legacy code is the best approach to analysing, understanding and maintaining it. UMLStudio can automatically convert C++, Java, CORBA IDL, PHP 5, and Ada 95 code into OOA&amp;D notation faster than any other CASE tool. </p></li> <li><p><a href="http://www.codedrawer.com/" rel="noreferrer" title="codedrawer for C++">CodeDrawer for C++</a><br> The CodeDrawer converts source code to visual based diagrams.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
