Viable is a plugin for the Eclipse environment that provides an interface as similar to vi (specifically Vim) as possible while maintaining access to all the powerful features of Eclipse. It supports visual block mode, common normal mode actions, command line mode (including command line history), "window" splits and management, regular expression search and replacement, and external filters and commands.
Bviplus is a console ncurses based binary file editor (hex editor) with Vim-like keys and features. It can quickly open/edit/save very large files (> 2GiB). It can perform regexp-like pattern searches in hex or ASCII windows. It features search highlighting, multiple undo/redo, a tabbed multiple file interface, visual selection, cut and paste (which works between files as well), blob coloring, and more. It can run external programs on selected data, supporting any program that reads stdin and writes stdout. It has few dependencies for easy portability.
