(Build b757) – 12 Dec 2014
Whether you just started a new job, inherited someone else’s project, or just have a lot of code to navigate, Understand has a lot of features to help you figure out a new or confusing project.
These graphs provide a quick way of seeing how the major code directories are related to each other. In this case I can easily see that the directories “common” and “ri” are important and used by almost everything. The dependency graph lets you drill down to the class and function level and filter out things you aren’t interested in, making it a great tool for exploring.
A quick way to see how the different classes in the project are related.
Complicated functions can make more sense when you can walk though the control flow logic visually.
Imagine browsing the source for a function and running across an unfamiliar variable, what is it, where was it defined, is it global or local? The Info Browser was made to answer questions like that. While not as pretty as the graphs, the Information Browser (IB) is probably the most powerful feature of Understand.It displays almost everything Understand knows about the selected entity: the initial value, relationships to other entities, everywhere it is referenced, sub-entities, basic metrics, etc. Just right click and select View Information on just about anything.
The Contextual Information Sidebar(CIS) updates dynamically based on where focus is in the editor, showing pertinent information about the surrounding structures and entities. It provides a quick heads-up display to provide context on whatever you are looking at.
If you’re exploring more than writing code, browse mode can save you a few mouse clicks, it changes entity names in the editor to hyperlinks that update the Info Browser and jump to the definition of the clicked entity.
As you make sense of the code, you may want to make notes on what you’ve learned. Annotations lets you make notes on entities without modifying the source code. You can choose to share those notes with others on your team or keep them private. Annotations are displayed inline with the code as well as in the Info Browser. That can also be displayed as a list and searched so you can quickly find the the right note.
There are many other features in Understand that may prove helpful in your situation, for a more detailed feature overview see this video.
You can grab a fully functional eval version of Understand and get started now!
To install just go to Tools->User Tools->Import
We finished our official testing this morning and are happy to announce support for Windows 8.1. Our testing was done with Understand 3.1 build 694 – however earlier builds of Understand will probably work just fine.
Diving into the API documentation can be a little overwhelming, so here is a collection of tutorials to get you started.
With build 642 we’ve added an awesome new feature called Background Parse. It is designed to let you get right to work on your project as soon as Understand opens, instead of needing to wait for the parse. Right away you’ll have access to the Project Browser and Editor windows, and as soon as the parse is finished, everything else will be available.
Other features added since the release of Understand 3.0:
In the past we have used the Visio API to export Understand’s graphs to Microsoft Visio. Understand would attempt to launch Visio and use the API to interactively draw the graph in Visio. There were several problems with this approach, the nodes and arrows of the graphs were not adequately connected, and in some cases the API would refuse to launch Visio. Of course this approach also required that Visio itself be installed on the same system as Understand.
Some graphs also have an option to export to the graphviz .dot format. This option is only available to newer graphs that are generated using the graphviz engine in Understand. Some older graphs use a different layout engine so that option is not available for them.
We are excited to announce the release of Understand 3.0 (build 611 and later).
We don’t like to make you wait for new features, so many of these features were already added in beta form and you may be familiar with some of them. There is an updated manual covering all of these new features, and several new floating licensing options are also available. The upgrade to 3.0 is free as long as your maintenance is up to date and Understand 2.5 and 2.6 Licenses will also work with Understand 3.0. Grab Understand 3.0 here
A node-locked floating license is designed for a single machine that many users will be accessing, such as in a lab or a secure environment. It is similar in concept to a Standard Floating License but no license server is needed, and it will only work on the one machine.
This license is ideal when the license needs to be shared between different people on different networks, or if there is a lot of traveling involved. The license is mailed to you on a USB drive. As long as that drive is attached to the computer, Understand will work. The license dongle can be shared between users as needed.
Dongle licenses expire after two years and will need to be replaced. There is an additional fee for new and replacement dongle licenses to offset the setup and shipping costs.
We just added a plugin to identify duplicated lines of code. You can grab it in the API/Plugins section of the support page.
Update April,26 2012 – I’ve made some extensive changes to this script to improve performance and remove repeated results
