    iSphere

    iSphere

    The iSphere Project for and RDi 9.5.1.3+

    The iSphere Source Code has been moved to GitHub (https://github.com/rdi-open-source/isphere) on January 3rd, 2024. The update site is still available on SourceForge, as is ticket management. iSphere is an open source plug-in for IBM's Rational Developer for i 9.5.1.3+. It delivers high quality extensions to improve developer productivity. IBM's current Eclipse based Integrated Development Environment (IDE) is a huge step beyond SEU, but it still lacks features available only on the green screen. That is where the iSphere Project comes into play, filling in those gaps. The iSphere library requires V7R1 or higher. For lower releases you can try to compile the library from an i Project by hand. Refer to the iSphere help for details. Available at SourceForge since December 3rd, 2013.
