table exactly and I fear that it makes the ACIP->Tibetan converter code a lot uglier. The TODO(DLC)[EWTS->Tibetan] comments littered throughout are part of the ugliness; they point to the ugliness. If each were addressed, cleanliness could perhaps be achieved. I've largely forgotten exactly what this change does, but it attempts to improve EWTS->Tibetan conversion. The lexer is probably really, really primitive. I concentrate here on converting a single tsheg bar rather than a whole document. Eclipse was used during part of my journey here and some imports were reorganized merely because I could. :) (Eclipse was needed when the usual ant build failed to run a new test EWTSTest. And I wanted its debugger.) Next steps: end-to-end EWTS tests should bring many problems to light. Fix those. Triage all the TODO comments. I don't know that I'll ever really trust the implementation. The tests are valuable, though. A clean implementation of EWTS->Tibetan in Jython might hold enough interest for me; I'd like to learn Python.

/**
|
|
* This ActionListener is like any other except in the way that it
|
|
* handles exceptions or errors thrown during the execution of
|
|
* <code>actionPerformed()</code>. Because event listeners are on
|
|
* threads, an exception during <code>actionPerformed()</code> is just
|
|
* printed out on the console by
|
|
* <code>java.awt.EventDispatchThread.run()</code>. It does not cause
|
|
* the program to terminate. In our code, it helps developers more
|
|
* quickly get to the root of a problem if the program terminates as
|
|
* soon after a problem as possible.
|
|
*
|
|
* Thus, this class calls <code>System.exit(1)</code> when an
|
|
* exception is throw by <code>theRealActionPerformed()</code>, which
|
|
* is the method that subclasses should implement.
