[Lily4jedit-devel] My near plans

[Joshua K. <jos...@gm...>]

Hi,

here is some stuff I planning to work on for lilytool.

1. Convert To Lilypond macro. and support for MusicXML.
A macro which allow user to chose a file (eg. midi or musicxml) and
convert it into a new file or replace the buffer file, something like
the convert to newer version function.
I have tried Xalan on the command line with xml2ly. I'm not sure if i
should import the jars into lilytool. One way i think of doing is to
allow user to specify path to the jar (or maybe to another xslt
processor). I tried to create some transcent classes with XSLTC but
didnt work out for me. I also find that inserting a \version "1.7.0"
from the generate ly is quite usefully as it can be converted to the
newest version easily (xml2ly was using a slightly older syntax).
As xml2ly give absolutes pitches, I tempted now to write a macro to
convert absolute pitches in selection to relative pitches.

2. Learning how to use the macrohelper classes
 - to find out whats the pitch/duration of the note in the buffer so
its possible to edit it, and to be able to insert relative notes from
the "Piano input mode".
 - improving someother functions that uses the helper classes.
Bert, do you think for articulations/appendnotes macro, instead of
checking if cursor is infront of notes, but notes behind the
selection/cursor should be placed into the iterator maybe by search
for the next space. This way, a selection of notes hightlighted, by
not hightlighted thru out would work as well.
eg. {a b c}is  can covert correctly to a-> b-> cis-> instead of a-> b-> c->is 
{} is where highlight stops and end.
About the what beat, is it possible to backmatch more to find the
duration of the notes if not yet known. Or could the values of note be
stored in the sidekick parser?

3. Note visualiser
I'm thinking of modifing Nifty from http://niffty.sourceforge.net for
displaying notes. What do you think?

4. After all these, I can work on to integrate these into the Keyboard
class to make sure all is working esp. the Keybindings Actions.

5. Then, I'll try to improve on the playback experience - score and midi.

I'll hope to bring good news in time to come!

That's a good idea. Xalan is included in the XSLT plugin, so we can make 
a dependency and use it. XSLTC is somehow too rigorous, but JDK 5 uses 
this as default xslt processor.

I hope that won't be too difficult. But perhaps they need some more 
hacking. If you decide to change something important, please ask me.

Have you updated your installation to the last CVS version? That does 
work exactly like that. And I'd like to note that a growSelection() 
method has been added that will expand the current selection to the notes.

Yes, I will make the what-beat macro work this way.

Lilypond's syntax is so flexible, that our visualization will be very 
limited. But it really can be useful.

Great, however, I'd prefer quick insert mode on visualization.

Fine, as you wish :-)

ARrr.. sorry my pc in school ran out of memory and then the mail was
accidently sent before i could finish my mail..

Thanks for the info, I found out that Xalan in included in JDK 2 (1.2)
too... so actually there is not need to download the xslt plugin as it
will be an extra 2.1 MB for users.

However, now I run into new problems... where should i place Guido
Amoruso's xml2ly files? If they are placed in the jar files, i cant
run the command line on them.
And im not sure how the getClass().getResource() will work with the
classes, but i'll just try... that why i was thinking using XSLTC
would solve the problem because it would generate the translet classes
so u wont need to specify the stylesheets.

Sure... I think the classes are quite usefully now... I'll ask you
when items come to my mind.

Ha... after trying to study their sources... i got a little scared...
They have many class files just for displaying... It may take me some
time to understand using it.

Btw have you tired Roudoudou ( http://roudoudou.sourceforge.net/ )?
Seems a pity that the project is not complete. Their method of
rendering is using images.

Anyway, if you are wondering why Alt-Tab sometimes dun return jedit
view from J-Dvi, I guess is because everytime u move ur mouse over the
jdvi, focus is returned to the jdvi window.

Thanks Bert again...
Actually I sort of figured that yesterday (getting url was the key
point)... but I got too sleepy before I could send another mail or
update the cvs. Anyway my way of implementation was writing the result
stream into a completely new file, i thought that adding  to the
buffer was make the ly file messy esp. huge musicxml imports.

anyway, I have just commited an "unstable" version into the cvs , so u
might like to check it out.

about the UnixName thingy... you are correct... I did run into problems...
after using my regex to replace the characters all the spaces with a
backslash infront,
the command seems ok. except the lilypond process do not starts.

I check the activity log, its says,
lilypond cygdrive/c/folder\ with\ spaces/test.ly <--- this is okay
cd cygdrive/c/folder\ with\ spaces/ ; cygdrive/c/folder\\ with\\
spaces/test.ly <--- nothing happens after this

typing the first line into the bash would work. but i do not know why
is there double slashes in the second line.

Time to rush to school!
see Ya

In the second line, did you leave out "lilypond" on purpose?

Hth,
Dscho

P.S.: You do awesome work! I am busy until the end of the year, but after
that I plan to participate more actively in lily4jedit again...

Nowhere. We should really use XSLT, but no translet classes but the XSL 
stylesheets. I'm sure they work with the XSLT classes.
See, that's all (in a draft):
factory=TransformerFactory.newInstance();
source=new 
StreamSource(getClass().getResource("something.xsl").openStream());
(or: source=new StreamSource(new 
URL("jeditresource://LilyPondTool.jar!/something.xsl").openStream()))
transformer=factory.newTransformer(source);
writer=new StringWriter();
transformer.transform(new 
StreamSource(getClass().getResource("file.xml").openStream), new 
StreamResult(writer));
textArea.setText(writer.toString());

Quite simple, isn't it?

The problem is the syntax. Many lexer states, lots of token types etc.

I don't think that that project is ever could be finished, because it 
was conceptionally bad.
