We design and demonstrate the feasibility of extending the open source Eclipse integrated development environment (IDE) to support the full range of capabilities now available to Java developers but for Fortran. We have experience in this process from having done analogous SBIR work for the Ada language with the Navy and Missile Defense Agency. As was the case for Ada, there is an existing but insufficient plug in for Fortran now available for Eclipse, namely Photran. We will leverage Harmonia's past work on Rise plug-in for Ada, c, C++ to create product that builds on Eclipse Photran as well as pFUnit and FUnit. Facilities we will implement include annotating source code as an overlay to the existing code, so that developers learning about the code are free to mark it up without affecting the original code, and creating various views tracing execution, showing potential concurrency, etc. We also integrate unit testing, graphical editing of workflows to create scripts that are used with Fortran, support the analysis and porting of Fortran code to different target architectures, and provide a web service link to accommodate cases where the Fortran compiler runs on a different machine from the IDE. Our goal is a 25% productivity improvement.
