Re: notes regex expression

I have been using a perl regular expression to parse lilypond notes for my own
application,
which handles guitar notes with possible right hand, left hand, plectrum,
string, glissando markings.
Thus it only includes some of the features of lilypond notes. It assumes
english note names
(easily modified).

function to end melody with rests to end of measure
I need to fill in the end of a score (a melody) with rests to the end of the final measure, if needed. Any ideas for how to do that, like writing a new function or ...? Thanks, Jim ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
keyboard graphic
I need to display small graphics of a piano keyboard with selected notes indicated by color. It will be used similarly as the guitar fret diagrams and actually in conjunction with them (and with standard and tablature notation, and explanatory comments) as guitarists examine chord voicings. I've found a few things but thought I'd ask here if some lilypond user has developed such a graphic in the system. Or, an expert advice on where to begin to develop one myself within lilypond, would be most appreciated. My wish list is parameters for range, width/height, and pressed keys; labels under the pressed keys would be a nice plus. Thanks, Jim ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
make many icons
I want to create about a hundred icons that contain short (2- 5-note) rhythms or melodic shapes, without staff lines. They will have no staff (which I see how to do). Ideally I could write them all in one file and invoke lilypond to create the hundred or so svg files. (My current solution is to create individual files and compile, with perl script.) Any advice about svg settings, lilypond input format, etc., to create many icons of short phrases? Thanks, Jim ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
new lilypond guitar site
Hi, Although it's still early days... http://GuitarAvatar.net creates scores for student/teacher use. Scales, arpeggios, rhythms, melodic patterns, audio, lots of fingering alternatives. Chords/harmony in active development but not live yet. Examples of fingering approaches from the chapters of a book in development. And no doubt plenty of bugs in what is live ;>) I thought you lot might like to see how I'm using lilypond. Peace, Jim ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
fill last measure with rests?
Does there exist a directive that will automatically fill the last measure of a voice with rests? If not, any pointers for programming such would be welcome. ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
fill last measure with rests
Is there a directive that will automatically fill the last measure with rests? For instance, if the music ends on a quarter note on the first beat of a 4/4 measure, the directive would fill that measure with 3 beats of rests so that the measure is filled to the bar line? (I'm generating scores algorithmically and this would be a pleasant shortcut ...) Peace, Jim ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
Completion_heads_engraver and repeated marks
When using the Completion_heads_engraver,
I'm having a problem with repeated fingering markings in my guitar music,
as described in the comments included in these three staves.
.ly and .png image attached.
I have written external code to insert ties across moments and bar lines myself,
but I'm hoping there's a fix within the existing lilypond system that I've
just not found in my state of internals, and general typesetting, ignorance.
(I much prefer the first version, as I'm processing scores algorithmically
and they're a lot easier to parse with the < > groupings, especially
with the right-hand markup syntax as "\RH #2 " (space at the end required) )
Thanks all,

The web program now takes 1 second on a small score instead of 30 seconds I then re-edited /Applications/LilyPond.app/Contents/Resources/etc/fonts/local.conf so that both these lines appear one after the other: ~/.lilypond-fonts.cache-2 .lilypond-fonts.cache-2 That's so that when a home directory can be found, lilypond will use the cache there instead of the one in cgi-bin (Caveat: there well may be an easier way to accomplish this - but this works at least.)

lilypond ram disk
Has anyone had good - or bad or indifferent- results by installing the lilypond software onto a ram disk? I find that my fairly spiffy server, typesetting a very small score, takes about 12-15 seconds ... unless I've just typeset another one, and the program is still mostly loaded in memory, in which case it takes maybe 3 seconds. If I could make that speedup permanent, it would be huge for my (interactive) work. And that's what a ram disk may possibly enable - anyone done this?

Re:Two possible bugs when dealing with Automatic note splitting
I posted some details about this a week ago, No, you didn't. Not wanting a repetition of fingerings and string numbers would be a feature request: I don't think that would ever have worked differently. -- David Kastrup Ah, true. I reported fingerings and string numbers being repeated unnecessarily when automatic note splitting was invoked, whereas this new post reported some accidentals being repeated in somewhat similar circumstances. Pardon my confusion. Since I find the note splitting unusable with the proliferation of incorrect fingerings (incorrect in the sense of how scores are normally fingered) I do request this feature. I would be willing to tackle it myself if I can ask someone to help me identify the parts of the code which would need attention. Before the rest completion was added, I wrote some score filter code that handled splitting, so I can just use that for rests and notes for the time being.

Content-Type: text/plain; charset=iso-8859-1
Hello,
I think I found two possible bugs when dealing with Automatic note
splitting.
1) when a note has an accidental and it has to be split, the ligaturas look
out of place.
2) when a note has an accidental (regular accidental, or forced accidental
with an !, or even due to *dodecaphonic style*) and it has to be split,
these accidentals appear in all repeated notes.
Here is an example:
\version 2.17.26
\markup {This works perfectly well}
\new Voice \with {
\remove Note_heads_engraver
\consists Completion_heads_engraver
\remove Rest_engraver
\consists Completion_rest_engraver
}
{
g'2\pp~g'8. f'1\mf a''2..\mf cis''4..\ff
}
\markup {But this don't, the ligaturas are out of place when notes have
accidentals}
\new Voice \with {
\remove Note_heads_engraver
\consists Completion_heads_engraver
\remove Rest_engraver
\consists Completion_rest_engraver
}
{
g'2\pp~g'8. fis'1\mf aes''2..\mf cis''4..\ff
}
\markup {Also, accidentals (including forced ones with ! and with
dodecaphonic style) are repeated for all notes...}
\new Voice \with {
\remove Note_heads_engraver
\consists Completion_heads_engraver
\remove Rest_engraver
\consists Completion_rest_engraver
}
{
g'2\pp~g'8. f'!1\mf
#(set-accidental-style 'dodecaphonic)
a''2..\mf cis''4..\ff
}
The result can be seen on this link:

So are these bugs or am I misusing the rhythm splitting?
Thanks a lot,

Re: lilypond slowdown in CGI web program
No one else reported the same problem on mac w/apache (or anywhere else) -- in brief, a 30 second delay running lilypond called from web page. But just to finish up, I did get some expert attention and I tried several things, and *something* worked, but I'm not sure what was the change that actually solved the problem. After including the original post, I append some of the troubleshooting exchanges, and, as I say, something did finally work. (And by the way, I tried all sorts of things, permissions, apache config files, ad infinitum in a subjective sense.) Thanks to Jan Nieuwenhuizen.

click track lead-in invisible bar
I'm generating a click track. I need it to start a measure (or two) before the music in a staffgroup. I want the extra beginning measure to be hidden, so it doesn't show up in the typeset score, but just sounds in the midi output. I already have the clicktrack hidden. I just need it to start a measure early, without displaying an empty measure in the score. Thanks for considering my problem, any pointers or suggestions will be most appreciated. -- Jim Tisdall ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

Re:completion_heads_engraver within a bar
Many thanks for the help with completion_heads_engraver.
I've got a related question about completion_rest_engraver
In this example, I'm trying to split the rhythms in bars of 4/4
time, so that note values that span the beginning of the third
beat, are rewritten with ties. (The idea is that it's easier to
read rhythms in 2-beat chunks with ties between them.)
But I'm trying to do a similar thing with rests.
I'd like to have the rests that span the 3rd downbeat, to be split
into two rests, the second one starting at the 3rd downbeat.
Either I'm using the wrong syntax for \with, or the
Completion_rest_engraver just doesn't do what I would desire, or ??
This example score is 4/4 time and I'm asking for adjustments
every 2 beats (with 1/2). The rests in the 2nd and 3rd bars
span the 3rd downbeat: I'd like to get a quarter rest followed
by an eighth rest, and an eighth rest followed by a quarter rest,
respectively, in those bars.
Peace,
Jim

completion_heads_engraver within a bar
Relative newbie alert. I'd like to have the action of the completion_heads(rests)_engraver *within* a bar --- so that, for example, rhythms that cross over the start of the 3rd beat in a measure of 4/4 rewrite as two groups of two-beat rhythms with a tie between them. (Also, between bars as before). I had the idea of changing the time signature to 2/4 (in that example), calling the completion_heads_engraver and completion_rests_engraver, and then wrapping that back into a 4/4 time signature. But I'm not sure if that's the happy path to take. (I'd also, for example, like to handle 3/8 time signatures, by rewriting as 3 groups of 1/8 beat-long groups, with ties between them as needed. And etc...) I'm generating random rhythms from user input, so this will be a help. I've actually got a perl rewrite program that's mostly working, but then I found the completion_heads_engraver and realized that my needs might already be met by the lilypond system. Any built-in solution or sage advice would be much appreciated. Thanks for your help, and Peace, Jim ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
lilypond on webserver
I'm making interactive typesetting to provide material to users of a music book. First pass, I'm using mac pro system and perl CGI and apache 2.2 server. (I've programmed in scheme in the past, but perl is likely the best - quickest - tool for what I'm doing.) 1) I don't see a way to have the actual graphics (e.g. png) output to a pipe like STDOUT, instead of to a file, when invoking lilypond, on a unix command line. Right? 2) I'm getting an error message to STDOUT (appears on my web page) related to permissions of webuser ... anyway, it's *** Warning: GenericResourceDir doesn't point to a valid resource directory. the -sGenericResourceDir=... option can be used to set this. Advice on how to pass that through to ghostscript when compiling a score with lilypond? 3) Has anyone ever put lilypond into webserver memory, using ModPerl or similar, performance-enhancing, facility? 4) Are there any lilypond/perl programmers within the sound of my voice? I'm developing some typical perl-style parsing and transformation and system-calling perl code for lilypond. I'd love to not reinvent this wheel.

publish music book
I'm preparing a book for publication. My book incorporates many short examples and a fair amount of text. I am developing a web site so that readers can be presented with customized exercises and hear midi playback. The complete exercises will be only available on the web. I've got a couple publishers interested (I've published books before). Lilypond has several methods to combine text and examples. One is lilypond-book, but due to the many examples in my chapters, I find that is too slow, so I'm deciding on other ways to include the graphics. No problem since everything is made possible, especially for a programmer. Probably some combo of lilypond with make. If you've been down this road, providing a book that incorporates lilypond typesetting to a publisher, I'd be very grateful to hear about your experience and advice on successful practices as well as pitfalls; and in past experience, which publishers accept/dislike lilypond and may prefer other formats for submissions.

sudo frescobaldi for music view
Hi everybody. I finally got frescobaldi running on my mac pro os x 10.7.5, by backing out of previous installs and using macports instead -- and by lots of trial and error. The Music View pane now opens and works ... but only if I start up frescobaldi with sudo frescobaldi. Otherwise, with just frescobaldi and no sudo, the graphics start up without the Music View pane, but no error messages. (A previous post by Paul Morris had recommended sudo python setup.py install for poppler-qt and that did seem to work, but maybe is a cause of this.) Anyone seen this, and have an idea for what's wrong? Nothing obvious that I've seen yet. (I'm an old Bell Labs unix hand and a programmer, but I have little python or mac sysadmin experience.)

newbie guitar fingering layout question
Greetings! I'll introduce myself after asking my question.
I'm new to Lilypond and have a question about laying out some
fingering in guitar material for a new book I'm writing. I'm
not neglecting the copious documentation, but I'm still on the
learning curve for sure and have missed or misunderstood a lot
as of yet.
Using LilyPond 2.16.0, modified the scripts.scm definitions of
\upbow and \downbow so they are DOWN instead of UP (couldn't
see a way to do that in the score ... yes, I'm a newbie).
The following small example produces a brace of standard notation and
tablature:
lilypond
\new Staff {
\clef treble_8
\set fingeringOrientations = #'(down)
\set stringNumberOrientations = #'(up)
\set strokeFingerOrientations = #'(down) % these are RH
e\6\downbow-1 f\upbow-3 g\downbow-4
a\5\downbow-1 b\upbow-3 c'\downbow-4
d'\4\downbow-1 e'\upbow-3 f'\downbow-4
g'\3\downbow-1 a'\upbow-3
b'\2\downbow-1 c''\upbow-2
d''\downbow-4 e''\1\downbow-1 f''\upbow-2 g''\downbow-4
}
\new TabStaff {
\clef moderntab
\set fingeringOrientations = #'(down)
\set stringNumberOrientations = #'(up)
\set strokeFingerOrientations = #'(down) % these are RH
e\6 f\6 g\6
a\5 b\5 c'\5
d'\4 e'\4 f'\4
g'\3 a'\3
b'\2 c''\2 d''\2
e''\1 f''\1 g''\1
}
/lilypond
My main question is this: I'd like to have the bow and
left-hand fingering and right-hand fingering appear in the
space between the two staffs, in a straight line, so they
can be seen easily by those reading either the standard
staff above, or the tablature staff below. How to do? The
staffs are in synch, so I just need to take the fingering
info from the standard staff and push it down so it will
line up underneath (and therefore between the two staffs.)
As part of this, I'll need to figure out how to adjust the
spacing between the staffs ... well really I have many
things I need to learn how to do!
to introduce myself:
I'm a musician and scientist, published author and so forth.
I got interested in computer music way back when and ended
up working with Max Mathews at Bell Labs for seven years.
The computer skills I learned I then used in human genome
project. But now I'm back to full-time music. I've played
with some names ... I'm fairly eclectic.
I'm writing a large book on guitar technique, Sibelius didn't
have what I needed so I'm turning to Lilypond which does.
I like the edit-compile-run ; I'm trained in several computer
languages. I'm developing Perl classes to process my
Lilypond scores. I have programmed in Scheme but not recently,
but it's a comfort to have a real programming language embedded.
(Again, Sibelius with Manuscript seems a bit painful, although
it is a nice WYSIWYG and has many excellent features.)
Thanks and I'm glad I found this software and this community!
Peace,
Jim Tisdall
