As Tcl has been ported to the Java platform (http://tcljava.sourceforge.net/) certain C-based libraries have been left behind. Expect4j is an attempt to rewrite Expect in Java and provide bindings to the TclJava interpreter. The goal is to be able to port existing Tcl code bases that use Expect directly to Java without changes. The current version has successfully run a 10,000 line Tcl script which heavily depends on Expect for it operation.
Expect is the kitchen sink of IO control. It supports control of processes and sockets, and a complex method of match multiple patterns at the same time. These are needed in some applications, but it complicates the API a tad. Especially when it used in Java which doesn"t support closures natively. There are other libraries which offer a more concise API, e.g. enchanter (http://code.google.com/p/enchanter/). enchanter is a v
