New in Railo 3.1 is an interface to interact with the CFML debugger, FusionDebug. Now Railo developers have the opportunity to benefit from using an interactive step debugger.

• Increase your productively
• Improve code quality
• Debug your CFML code faster
• Better understand your code
• Accelerate the learning of CFML and existing CFML applications

What is an interactive step debugger?

Interactive step debuggers let you see what is happening in your application as each line of code is being executed. You can use the FusionDebug CFML debugger to set breakpoints, step over, into, or out of code, inspect variables (across different scopes), and watch expressions. Modify the values of variables as your code is executing, so that you can force specific execution paths. You can even stop on certain runtime exceptions to see what is happening, and add conditions to your breakpoints so they only fire when the expression evaluates to true. FusionDebug is particularly helpful when testing code that does not produce HTML output, such as components (CFCs), SOAP web services, Ajax applications, and Adobe Flex™ or Flash® applications that use Flash Remoting.

Why would I need a CFML debugger?

Debugging CFML pages usually requires using lots of <cfoutput> statements, <cfdump> or writing to log files. As applications grow more sophisticated with the addition of object oriented components, and the integration of Flex, it's becoming increasingly difficult to solve complex problems. FusionDebug solves these problems by allowing you to suspend any page or component during its execution and see all the variables used by that page. You can add specific watch expressions as well as set variable values while the page is suspended. Pages can then be single-stepped or resumed.

Do I have to edit my code in Eclipse?

If you use Dreamweaver, CFStudio, HomeSite+, CFEclipse or even a text editor, don't worry. You don't have to use Eclipse to edit pages, or change your development platform. You can still develop with Dreamweaver or whatever your favorite editor happens to be, and jump into FusionDebug whenever you need to work out a problem. FusionDebug is able to use your files from the software you used to create them.
