is basically that we use our own special ViewFactory, with a new
subclass of LabelView (the view RTFEditorKit uses for the nitty
gritty) that is aware of Tibetan.
There are a couple of nasty hacks still here, and Swing's
documentation for doing what I did was quite poor. I searched the web
for hours, read the Javadocs and the tutorials, and consulted a Swing
reference book, but I still don't have tremendous confidence in this
solution. If it fundamentally doesn't work, though, we have to define
our own first-class Document, Element hierarchy, ViewFactory, Views,
and EditorKit. So let's hope it *does* work fundamentally.
I can't say for sure if this even works, as I have yet to run this
code on a machine where Jskad works properly. I had major trouble
installing the TMW fonts on Linux, and have yet to resolve it, even
after verifying via xlsfonts that the fonts were installed and then
changing TibetanMachineWeb.java to look for them. Because I haven't
tested this yet, a lot of nasty code is tagged 'DLC' and commented
out.
I fixed this the easy way, by checking the value of isEditable() before
cutting, pasting, or adding typed text. I may have missed a spot, but
checking at a lower level is a bit less efficient.
Fixing this the hard way, the keymaps-and-overridden-default-action way,
seems like it will make the code uglier, not cleaner. And it won't get us
closer to fixing the killer bug, 614475, "Improper Line Wrapping".
string-valued preferences built atop java.util.Properties.
How it works: the jvm is asked first, and then the user's prefs file, if it exists,
then the system-wide prefs file, and then the built-in preferences. Finally, for
robustness, a default may be optionally hard-coded in the source.
I made several things configurable, too:
the default Tibetan keyboard
the default font sizes and faces
whether you want developer-only features enabled
Savant's file extension (.savant)
etc.
The only known problems are the following:
The default location for the user's preferences file is windows-specific,
arbitrary, and not in the user documentation. Likewise for the location of the
system-wide preferences file. You can change them using 'java -D', though.
There is no "Save preferences" option yet, and closing the program does
not save preferences either.
that you don't want one. It's on by default.
If you set another system property, every keypress in "Tibetan" input mode
causes an update to the status bar. The messages are for developers, not
users, so this option is off by default.
Updated to use the new log file facility.
comments.
Reformatted the code in processTibetan() in an attempt to understand what
it does. I'll soon commit some code that updates a status bar with "what
Jskad is thinking" in this maze of control flow.
Added a "Quit" option to Savant's File menu. Factored out the Close
option in doing so.
Exceptions in many action listeners are now handled by
org.thdl.util.ThdlActionListener or org.thdl.util.ThdlAbstractAction.
Many exceptions that we used to just log now optionally cause aborts.
This option is on by default for developers using 'ant savant-run'-style
targets, but it is off for users.
An erroneous CLASSPATH now causes a useful error message in almost
all situations.
Fixed some typos and bad links in Javadoc comments.
Added a simple assertion facility, but the overhead is suffered even in
release builds.
Factored out the code that sets up log files like savant.log and jskad.log.
