Implement a Console Using the TerrJava API
We have provided the example Java code in both Windows and Linux
for a Java application that implements a simple
TERR
console using the TerrJava API. This is similar to the console application in
TerrJava.main
, except that it accesses the TerrJava
methods from another class.
An interesting feature of this code is that the main
read-eval
loop detects when the current line cannot be
evaluated because it is an incomplete expression or string, and it accumulates
multiple lines until it does evaluate (or another type of error occurs). It
also calls into
TERR
with
TerrJava.evaluateToString
to retrieve the appropriate
prompt string for normal input, incomplete expression, or incomplete string,
which can be changed in
TERR
at any time.
- A Console Application
This is the Java code for a simple console application using the TerrJava API. - Run the Console Application
After you create the console application, you can test it using example user input and text output on Linux.
