[Jmol-developers] extensive changes: interpreter + applet

[mth <mt...@mt...>]

Jmol team,

I have good news and bad news.

The good news:

While I was on vacation the last week and a half I was able to do quite a
bit of work on scripting support and on the applet.
 * The script interpreter is running quite well. It runs as a separate
thread and interacts properly with redisplay. I think the repaint thread
synchronization technique can be applied to vibrations and animations to
improve performance. I wrote the lexical scanning in the tokenizer. This
eliminates the use of javax.util.regex, eliminating a problem on 1.1
browser JVMs.
 * I got the applet running successfully on the new code base. If it
detects JVM >= 1.2 then it applies antialiasing so that the rendering And
the script interpreter is available to the applet. I refactored a lot of
code so that there is much less code which is applet-specific.

The bad news:

 * This will be a big check-in. I changed a lot of stuff. I am sure that I
broke some things.
 * The applet has problems which loading the CDK AtomColorer. Therefore,
all the atoms come up in grey. Egon, I will need your help to figure out
what is going wrong
 * On 1.1 JVMs (IE and old netscape) there is a problem loading some CDK
classes. The error message says that the class is not found. But it is in
the jar files. I couldn't really figure out what was going wrong since I
wasn't online and didn't have access to resources.

Haven't actually checked this stuff in yet, but plan to do so later today
or tomorrow morning (European time).
