May be this will help on using jython within a Java application http://www.jython.org/jythonbook/en/1.0/JythonAndJavaIntegration.html#using-jython-within-java-applications

jython sounds like the way to go. So we just place the jython jar in dist/lib and the Python scripts somewhere in the src tree. I imagine the scripts are called through methods in the jar. Where should they go in the distribution?

If one uses jython, the Java implementation of Python, then it should be no harder than just including the jython jar file. Also no bindings would need to be created as jython allows Java and Python scripts to interact. One down side to jython is that it normally trails the official Python implementation by a little and so may not have all new language features. Also some say it is slow, however for small things it may not be too bad and it might be a way to allow people to script BrailleBlaster. John G mentioned not needing to distribute a Python runtime, well that is sort of true but not strictly as far as I know. One can bundle the appropriate parts of the Python runtime with a Python script, so removing the need to require the user to install Python. However as I said this strictly speaking still means a Python runtime is being used, it may just be the python DLL, but its still a runtime like those who work in visual C need to distribute visual C runtimes. This would need Java to C and C to Python bindings for the script and probably will not offer a general scripting solution like jython can. There are some libraries to help with binding Java to Python (they still go through the C layer). The final option is that one can require the user to manually install Python, butg that probably really is not the route to go for BrailleBlaster. Michael Whapples On 26/04/2012 02:26, John J.

This would still raise the problem of porting. I've found that the easy way is likely to be the hard way quite soon. So I favor a Java implementation of LEAN. Besides, we have to consider SWT compatibibility. Much of the work could be done by liblouis and liblouisutdml.

XSLT is fine there as you go one way (MathML to LEAN), however BrailleBlaster may want to go both ways. One could use jython to include the python version John G is writing, but that might not be the most efficient way although it would save some effort in not creating a Java version as well. Michael Whapples On 26/04/2012 01:19, John J. Boyer wrote:As you know, I would prefer to do everything in Java except for the liblouis and liblouisutdml libraries and a few other things like hunspell. XSLT sounds interesting, but I'm not sure it's the best approach for BrailleBlaster.

The only issue with an XSLT implementation would be that it would only go MathML to LEAN but not the other way, but XSLT has the great advantage that it can be used in many different languages such as Python, Java, javascript and probably many more. In general though, I would recommend it as a math notation for most people (those who are doing a large amount of maths may still prefer LaTeX, but they probably would be doing the whole document in LaTeX). I will be very interested to see how it works in practice and hopefully if people feel improvements can be made they will be able to be incorporated. Michael Whapples On 25/04/2012 23:15, John J. Boyer wrote:The forwarded mesage contains a link to a preprint of a paper on the LEAN (Linear Editing and Authoring Notation). This is a very compact mathematical notation based on Unicode and was developed by John Gardner of ViewPlus Technologies and co-authors. It may be used for authoring math in BrailleBlaster. Translating LEAN to Braille should be a relatively straightforward matter of developing semantic-action files and liblouis tables. One big question is how LEAN can be integrated into BrailleBlaster, since the current implementation is in Python. I'm sure Michael will have something to say about this. The paper is a good read and gives an overview of currently-used math notations before describing LEAN.

I did. It is at: http://www.access2science.com/jagqn/More%20Accessible%20Math%20preprint.htm LEAN is Linear Editing and Authoring Notation and is described in that paper. There will soon be a MS Word macro permitting one to flip MathType equations to/from LEAN notation similarly to the way you can now flip to/from Latex. LEAN and other Unicode symbols are all pronounceable using screen reader speak dictionaries.LEAN was specifically designed to work well with current technology screen readers, and I believe that most blind people will find LEAN to be very intuitive, making MathML reading in audio very straightforward. And authoring math as well. More on that in a few weeks. I should acknowledge many useful conversations with Michael Whapples on this topic. Michael's intuition has undoubtedly made LEAN better than it was when I first started.
