To submit a PR, in DrRacket, click on the Help menu, choose "Submit Bug
Report...", fill out the form, then click "Submit". It may help Robby
and/or Matthew figure out what the problem is if you do this on one of
the computers that doesn't render the chants properly.
BTW, as a musician, I think your project is pretty awesome. :D
My pie-in-the-sky dream is that someday, someone will port LilyPond to
Racket, because its abstraction mechanisms could be better. I'd love to
try programmatically generating music (with constraints or some other
kind of guidance), engraving it, and then playing it.
Anyway, good luck!

Thank you for the suggestion, but that didn't work on XP or Ubuntu. Should I
submit the issue to Racket's github? I'm new to programming and don't know
what the protocol is for things like this...

Oh, I see. I'm sorry I don't know what is going wrong. Different
versions of cairo/pango could be relevant, possibly.
I doubt it is going to matter, but if you change the expression on
line 932 in collects/mrlib/image-core.rkt:
(send dc draw-text (text-string np-atomic-shape)
(real-part p)
(imag-part p)
#f 0 θ)
by turning the #f into a #t, does that change anything?

I'm sorry, I don't think I've explained the problem I'm having clearly.
I have fonts that I'm using that map latin characters to neumes for
byzantine chant music. So pressing "1" gives me a particular musical
symbol,
and "a" gives me another symbol. I am trying to use text/font to render
those symbols, so I call it with a "1" but I'm getting a "1" instead of
the
musical symbol on certain platforms. This method works fine on Ubuntu
12.04
32bit and a Debian system that another user tested it on (I'm not sure
of
the version info), but it isn't working on Windows XP and on Ubuntu
12.10
64bit.
If you go to https://github.com/muraiki/byzscribe and scroll down to the
picture, you can see what the output should look like. On platforms
where it
doesn't work, instead of getting the musical symbols I simply get the
textual string that should map to those symbols, such as 01a.
You can download the font package, which includes a PDF with a character
table, from here:
http://www.stanthonysmonastery.org/music/ByzMusicFonts.zip
The character table is EZ-CharacterTables.pdf
The other symbol fonts that I've tried work in the same way, although
instead of musical symbols they have other things like snowflakes and
shapes. Those aren't the fonts that I need to use, but I wanted to make
sure
that the problem didn't lie in the byzantine chant fonts. On platforms
where
the byzantine chant fonts don't work as expected, no other symbol fonts
work, either.
I'm sorry if this is a bit confusing. Thank you for your help!

If you want to use, say, α, then you need an actual α in the string,
not
an "a".
I don't know how the dingbats work, but certainly that's how it works
for characters that are in the unicode character set.
(You can type those characters by using their LaTeX equivalents and
then hitting control-\ or alt-\ (depending on the platform).)

Now I'm experiencing the same problem in Ubuntu 12.10. No symbol
fonts
render when using text/font; I only get the latin text equivalent. I
tried
this using the Dingbats font built into Ubuntu along with custom
symbol
fonts I had downloaded. Both Dingbats and the other symbol fonts I
downloaded work fine in other programs.
The system where this did work correctly was an Ubuntu 12.04 machine
(running under a VM). The Ubuntu 12.10 machine I'm using now is a
fresh
OS
installation using the 64-bit binary downloaded from the Racket site.
Is anyone else using Ubuntu 12.10? Can you try running the following
code?
(require 2htdp/image)
(text/font "test" FONT-SIZE "black" "Dingbats" 'symbol 'normal
'normal
#f)
This should render some triangles and a snowflake, not "test".
Thanks!

The text/font function ultimately just calls find-or-create-font

the font details and then draw-string on the dc<%> with the string,
so
I guess that this is either a problem at that level of the Racket
GUI
system, or something that is just different about how Windows works
from other platforms. (Sorry I don't know the right answer here.)

Hi all,
I'm a newcomer to Racket and I ran into a problem with the
text/font
function in 2htdp/image. stamourv on #racket helped me diagnose
this,
and it
seems to be a problem confined to Windows XP. When using text/font
with
a
symbol font like Wingdings or Symbol (standard symbol fonts
included
with
Windows) the character is not rendered. Instead, I get whatever
the
equivalent Roman character would be.
For instance:
(define testingfont
(text/font "012abc" 36 "black"
"Wingdings" 'default 'normal 'normal #f))
If I then type testingfont into the interactions window, instead
of
rendering a series of symbols I get the input string 012abc
instead.
I
also
tried using 'symbol instead of 'default. We tried the same code on
Debian
(stamourv) and Ubuntu (me) and it worked fine on those platforms.
I'm running Windows XP 32-bit, and I am using Racket 5.3.1.
Thanks!
