Builder, a new IDE for GNOME
Builder is a new effort to bring a modern development environment to GNOME. It aims to bring together the core developer tools that we expect from an IDE today. Auto completion, error reporting, documentation, debugging, VIM keybindings, split view, build management, hardware integration, simulator, code navigation, robust search, and more. To make GNU/Linux programming more accessable, Builder will include tutorials for beginners and intermediate developers right in the IDE.
The project is under heavy development and funded by both Christian Hergert and the community at large.
