We’ve added a new option to highlight entities that are defined but not used.

To enable this option go into Tools->Options->Editor->Advanced->Unused Entities

Right now this only works for functions and variables. Let us know if you find it useful, and if there are other entities you want it added for.

We moved our main office this week. 

We are still in scenic St George, near Zion National Park and less than two hours from Vegas. If you are in the area feel free to stop by and visit us!

Our new address is:

Scientific Toolworks, Inc.
249 East Tabernacle, Suite 200

Many users have asked us in the past if Understand could have better support for Templates and Overloaded functions. We are excited to announce that this is now a reality. Our engineers have worked hard to add a completely new C++ parser to Understand, which is available for Beta testing in build 586.

Our current C++ parser was written with the goal of being able to use fuzzy logic to handle incomplete, non-compiling code gracefully and as accurately as possible. It does a great job at that and will continue to be an important part of our toolset. Unfortunately that same feature caused severe difficulties in parsing templates and recognizing overloaded functions.  The new parser is more strict than the old parser and requires a more accurate project definition. If you plan on using it, please follow the instructions from this post to ensure your project is as correct as possible:  Improving Project Accuracy (C/C++)

To access the new parser, just check the new checkbox on the Languages screen when creating a new project or in the Project Configuration dialog.

We welcome and appreciate your feedback and comments on this new parser – please send it to us at support@scitools.com

We’ve made a few changes to how keyboard shortcuts are managed with build 586.

Key Bindings can still be accessed via Tools->Options->Key Bindings  but this page now lets you search for key binding, either by name or by the actual keystrokes. This page also has all of the key bindings in one place for easy browsing. The other change was to add a separate page for each Component(Category) of key bindings in the navigation pane.

While these are relatively small changes, we hope they will make life easier for those who rely heavily on keyboard navigation.

Understand now fully supports Python access to its underlying database! The new Python API allows you to write your own scripts that can create custom reports, generate your own metrics and in general make Understand deliver exactly what you want it to.

Getting Started

The Python API runs on your 3.x installation of Python, you can grab it from here if you need to install it.

Once you have Python installed you need to tell it where the Understand module is. The easiest way to do that is to add/modify the PYTHONPATH environment variable to include the module location, which is SciTools/bin/<System>/python. Also if you did not add Understand to the Path variable during installation, you will need to add the SciTools/bin/<System> directory to PATH.

Finally, to use the API you will need to put ‘import Understand’ in your script.

Documentation

The most up-to-date documentation will ship with Understand and can be accessed from the Python Console with:
   import understand
  help (understand)
A more readable version can be obtained with the python ‘pydoc’ command, which can generate an html version of the documentation. We also try to keep a current version of the Python documentation on the Manuals page.

Sample Scripts

The documentation includes some samples. More detailed example scripts are shipped with Understand in the SciTools/scripts/python folder.

Happy Scripting!

The new interactive Clustered Call Graphs show the function call graph, organized by file. There are several variants of this graph: Call, Call-by, Butterfly and Internal Call. They can also be accessed from the function, class, file or architecture level. These graphs can all be accessed from the Graphical View right click menu for the entity.

There is a new option for identifying and defining missing macros. The new tool shows what macros are not defined as well as how and where they are referenced. This makes it easy to see which missing Macro definitions would have the largest impact on your project.

Build 571 contains a completely re-written version of ‘und’, the command line interface for Understand.

The commands have been standardized and the tool should be much easier to use. Because of the extensive changes, this new version is not backwards compatible with older versions of und. The old und will still ship and has been renamed ‘undlegacy’ – current users will need to change the name of the binary for scripts to continue to work.

In general the syntax for running commands are similar to Subversion and should be much more intuitive than previous versions.

The new version also includes a cool new interactive mode that lets you specify a database and then continually run commands in it, similar to MySQL.

The help documentation has been flushed out extensively and should be much more useful – just run und help for a complete overview of how to use this great new tool. Also this post steps through each different method of using und and demonstrates some of the most common commands: Integrate Understand with your build system.

With this weekend’s release of Understand 2.6 Build 551, we are pleased to announce support for the COBOL language.  We’d love your feedback on it, and if you have some sample code you would like us to look at, we’d love to see it.
