Komodo Edit and Komodo IDE

A new QPL Add-on for Komodo Edit and Komodo IDE has been developed. This editor will let you develop QPL projects in one "write, compile, and view" environment. This is installed in Komodo the same way as a Firefox Add-on (and requires the Microsoft Redistributal Package for Windows).

If you will be using the QPL Komodo Add-on on a Windows computer, you may also need to install the Microsoft Visual C++ 2013 Redistributable Package (x86). This only needs to be installed the on your computer the first time you install the QPL Firefox Add-on. You do not need to install it again if you later install an updated QPL Firefox Add-on.

Copyright and User Support

The QPL software was developed by the U.S. Government Accountability Office, an agency of the U.S. Government, and thus is not copyrightable. You may freely copy and use the software and documentation, though at your own risk.

While GAO can not provide extensive end-user support, we are happy to provide answers to emailed questions and will use them to update the FAQs on this site. The documentation, however, is very extensive and the source code for all the files that run your questionnaire on your server are provided in the set up programs or are generated when you compile your questionnaire programs. An experienced PHP and MySQL programmer can readily examine these files to diagnose problems or discover how a new feature may be added. And we are, of course, interested to get suggestions for improvements or hear of innovative ways that you used the software.
