Traditional vi is derived from the 4BSD source and includes support for modern operating systems, 8-bit input, multi-byte character encodings like UTF-8, and features demanded by POSIX.2. It contains few additions beyond this, so it is of interest for those who look for a small but well-defined vi implementation close to that of most commercial Unix systems. It also has some features to cope with primitive terminals or slow connections.
Java+ is a Java preprocessor that adds its features to any Java compiler. It has long, multi-line strings with executable inclusions like Perl or Ruby, optionally segregates Java+ strings into ResourceBundle files, eliminates the need for JSP or ASP and their implied need for Java compilers on deployment servers (a security concern), and adds absolutely no overhead in either space or time. There are graphical and command line interfaces, and a simple, general, and recursive string syntax.
