jterm
JTerm is a swing component that roughly has the look and
feel of a Unix shell window: You can type text to some prompt and
after hitting Return the text is evaluated. You are shown
the result and you are presented with the next prompt. There is no
mouse cursor but a caret at the text insertion point. The cursor keys
can be used to move the caret (left and right) or to navigate in the
command history (up and down).
In accordance with the way swing
proposes to handle text, JTerm is implemented by defining a
subclass Session of Document. A single
JTerm window could handle multiple sessions (just call
setDocument).
The main application is interaction with
Java interpreters: to provide a shell window where you can interact
with Java objects. The "interpreter" can however be anything that
implements a very simple interface called
StringEvaluator. This contains only one method
evaluate that given a string returns a result string
together with a boolean telling whether the result string is a regular
result or in fact an error message (has influence on the color of the
result string).
