70b31558fa Tried to fix a crashing bug that happened when you converted TM->TMW
and then tried to convert that TMW to Wylie.  I swear it's Java's
problem (see the ugly stack trace in the code and decide for
yourself), and I tried replacing rather than
inserting-and-then-removing, but it didn't work.  I've left these
things as options.

32831b698f If bad (oddball) TM glyphs appear, then converting to TMW causes, by
default, all oddballs to appear once in the resulting document.
This'll help me find the correct glyphs for the oddballs, and it'll
prevent the average user from converting a document with oddballs.

0f724989b5 The Wylie 'M' used to map to TMW7.91, when it should map to TMW7.90.
I've fixed that.

I've also added a couple of Unicode mappings to give a flavor for how
multi-codepoint mappings will be represented.

TM->TMW conversion takes about 1 second per thousand glyphs on my
PIII-550.

tibwn.ini must now have, in the Unicode column, either nothing, or
0FXX(,0FXX)*.  E.g., 0F04,0F05 is valid.  Debugging code ensures this is

0235263ddf TM->TMW and TMW->TM conversion in RTF is now supported. I've
noticed that formatting is mostly OK but sometimes gets bungled slightly.
I tried everything I could think of, and now I'm passing the buck to Java's
RTF support.

TMW_RTF_TO_THDL_WYLIE (now misnamed) support TMW->TM
conversion (but not TM->TMW).  There is an automated test case for a
TMW->TM conversion.

I have full confidence in this conversion.  Even the smallest glitch in the core
functionality (not formatting) would surprise me.

Note that the JUnit test TMW_RTF_TO_THDL_WYLIETest sometimes fails
due to one- or two-line diffs between the actual and expected outputs.  This
is because Java's RTF support is not deterministic, I'm guessing, and is not
a real failure.  I'm too lazy to make a more elaborate sed/diff mechanism
that works on all platforms, and that would complicate the build anyway.

bfacd6c998 Accurate TM->TMW and TMW->TM mappings are now available. I've
verified this extensively and have full confidence that these mappings
agree with Tony Duff's Tibetan! 5.1 documentation (except as described
below).

To get them, I had to disregard Tony Duff's tables for a few glyphs: the
characters with ordinal 32 and 45 (space and hyphen in Roman ASCII,
space and tsheg in Tibetan).  For these glyphs, we must have mappings
from TibetanMachineSkt4.32 to something, etc., and those mappings were
not present.  I've normalized the mapping for these glyphs, as it is arbitrary
because the same two glyphs just appear fifteen times each.

6f0390c5d6 By default (controllable via options.txt), Jskad now fixes the Tahoma curly
brace problem upon opening any RTF document.

The TMW_RTF_TO_THDL_WYLIE test baselines changed because
I fixed (a while ago) some inconsistencies between the EWTS standard and
Jskad.

Conversion of TibetanMachineWeb8.40, @#, to Wylie now works correctly.

Unfortunately, though, typing @# doesn't produce 8.40, it still produces
8.38 and 8.39, two glyphs.

e2a9720d9b I've added a command-line converter,
org.thdl.tib.input.TMW_RTF_TO_THDL_WYLIE.  It converts RTF files
consisting of TMW characters to the corresponding THDL Extended Wylie.

It supports --find-some-non-tmw mode, which allows you to ensure that no
unusual characters will spoil the conversion.  The converter has built-in
intelligence that allows it to handle Tahoma '{', '}', and '\\' characters
properly.

The converter works on mixed Roman/TMW also, but --find-some-non-tmw
and --find-all-non-tmw modes are not as useful.

Invoke org.thdl.tib.input.TMW_RTF_TO_THDL_WYLIE, which resides in
Jskad's jar, with no command-line options to see usage information.

efa8fc1f25 DuffPane now has the start of a unit test suite. Invoke it via 'ant
clean check'.  Right now there are tests to ensure that typing certain
sequences of keys in the Extended Wylie keyboard gives the expected
Extended Wylie back when "Tools/Convert Tibetan to Wylie" is invoked.

The syntactically illegal d.wa now converts to Tibetan and then back
to d.wa (not dwa, as it did); likewise with the illegal g.wa.  wa
doesn't take any prefixes, but I prefer clean end-to-end
behavior. (jeskd doesn't go end-to-end, though.)

Note that you cannot successfully run the DuffPane tests on a Linux
box unless your DISPLAY variable is set correctly.  Thus, my nightly
builds will fail with an Error (as opposed to a Failure).

58f7371e66 I hope that Revamped the "Tools>Convert Tibetan To Wylie" feature that
converts TibetanMachineWeb glyphs to THDL Wylie.  Three-glyph and
four-glyph sequences with implicit "a" vowels are now handled
correctly, except for disambiguation w.r.t. things like b-la-g
vs. bla-g and d-wa vs. dwa.

pa'am, pa'ang etc. now work too.

Illegal Tibetan sequences now become very ugly, but "correct" Wylie.
Correct in the sense that converting it back to glyphs should get you
the glyphs you started with.

I also made a change to TibetanMachineWeb.java that I hope will clear
up problems with this feature when keyboards other than "Extended
Wylie" are selected.

Took nga out of the farRightSet [postsuffixes]; only da and sa belong
there, right?

I tried to get the system in a state such that I could run automated
tests of this stuff, but I ran into difficulties.  I have some manual
test cases; ask if you're interested.

f4a16f8e9d This commit is for my benefit only; these classes are not ready for prime time,
and the build system is not yet aware of them.

I'm adding some classes for representing legal tsheg-bars (syllables, for the
most part) in Unicode.  These classes were designed bottom-up (OK, OK --
they weren't designed designed, but I had to write down everything I knew
about Tibetan syntax somewhere).  The classes are aware of extended
wylie.  I doubt the Javadocs work yet, and I'm still testing (and am not
committing my testing code with these as it is not yet ready).

Next on my list--fix these up to reflect my new awareness of suffix particles
(like le'u'i'o) add classes to support syntactically incorrect Unicode
sequences.  Then add a UnicodeReader, and we've got the back end of
a Tibetan Unicode shaping system (like half of MS's Uniscribe or Apple's
Worldscript or FreeType Layout or Omega's OTPs).

A top-down design would not have included LegalTshegBar.  But now that
my itch has been scratched, potential uses are lingering about.  For example,
it would be nice to scan some input and break it into LegalTshegBars,
punctuation/marks/signs, and illegal stacks.  Then we could alert the client
of the illegality, its precise form, and its precise location.

The real system for turning a Unicode stream into an internal representation
suitable for conversion to EWTS/ACIP/XHTML/what-have-you need not be
aware of Tibetan syntax.  But to make the very best conversion from
Unicode to, e.g., EWTS, it is necessary to konw that gaskad is better
represented as gskad, but that jaskad is not the same as jskad.

53aa2e2309 Added jskad_doc.html (a revision of which is up at
http://iris.lib.virginia.edu/tibet/tools/jskad_doc.html) to the repository.  The
build puts this into Jskad's JARs, but Jskad itself does not allow for viewing
it.  In Java, that's a ten-minute job, but I haven't done it.

9eedfcd909 This is Tashi's TibetanSyllable class for sorting Wylie Tibetan.
It does not have many methods for determining the root letter, suffix,
and so on, but these should be easy to add. David, please use this
class to the extent that it and your new work overlap.
