I just added tooltips and went thru my "do list" and realized... I am done!

http://teamalgebra.com/

Done with the desktop-to-RIA port, that is: I am back to where I was on
the desktop application, except for (OK) an abiding need to get jsMath
to give up layout info after converting TeX to HTML -- but that is
manageable for now.

Eight weeks, including the bit about dealing with AWS and incorporating
jsMath and developing the Lisp/qooxdoo glue called qooxlisp.

The bad news is that Team Raw HTML won't have me to kick around any
more, unless something interesting happens on the qooxlisp end of
things; from here on out I will just be working on the functionality of
the Algebra application.

Of course that was the plan: use a good JS library to hide all those
whacky browser issues and avoid learning HTML and CSS (credit as well to
Franz AllegroServe and AllegroGraph) so I could concentrate on the beef.

Peace. Out.

Like it says on your site: "We seem to be missing an operand from the
equality."

Yeah, that comes and goes for me. It derives from my not having fully
wrestled jsMath to the ground. Once I am able to dynamically interrogate
jsMath for dimensions of generated HTML I should be able to understand
when/where/why it gets lost.

For the curious, it is related to the visible insertion caret that tells
user where they are typing. Inserting that tex code into a larger tex
expression randomly (well, I have not found the pattern yet) knocks off
the overall positioning.

I guess I know what I am doing this week. :) Besides this, I mean:

Thx! I meant "I am back to where I was on the desktop version", which
(a) means, yes, I will never be done and (b) means I lied because I
still had to wrestle jsMath to the ground.

Still not there yet on jsMath, but I have not seen the unpredictable
vertical jump in the few hours since I eliminated once probable source
of Heisenberg Uncertainty. A few hours is not much comfort, but anyway:

Known remaining problem is that some math will get outside its bounds a
little if you click around here enough:

http://teamalgebra.com/#TRAINING

.... but I just have not had the time (and I gotta run) to re-tune the
sizing logic since the breakthrough: jsMath lets you put math in a div
or a span. spans are for referring to math right in the middle of a
normal sentence, divs are for centering math in their own paragraph if
you will. I was using spans, even tho I was essentially giving each bit
of math its own universe, a qooxdoo embed.Html widget. jsMath was doing
its best to cleverly align the math with...nothing else! But it would
assume it was on aline of text and I guess do things odd vertically, or
odder than usual. Now just using a div.

Off to tend to this now: http://thelaughingstockatpngs.com/, a much
welcome change of pace for a homebound geek.
