Fwd: New Feature: musicxml2ly should consider colors of noteheads and stems
Forwarding to devel list - this is more patch proposal than bug report. Please comment if we need tracker issue for this... -- Forwarded message -- From: DaLa d.la...@gmx.de Date: 2013/7/20 Subject: New Feature: musicxml2ly should consider colors of noteheads and stems To: bug-lilyp...@gnu.org Hello, many thanks for all the software of the lilypond project. Yesterday I colored some noteheads in a piece of music using the format musicxml. I learned: the format musicxml supports color attributes for noteheads and stems. Unfortunately the script musicxml2ly.py in lilypond version 2.16.2-1 seems to ignore color attributes of noteheads and stems. I therefore would like to recommend the following changes in the scripts * musicxml2ly.py * musicexp.py I have made some simple tests - the changes seem to work. Maybe some additional regression tests are necessary. (and: I'm not familiar with the methods pre_note_ly of the Event classes - must they consider the color attribute? I don't know.)

Re: Ignoring note value when spacing notes and rests
Hello, 2013/6/15 Phil Holmes em...@philholmes.net I'm setting a piece of late 16th century music (it's in Musica Transalpina), and at this time notes and rests tended to occupy a space determined by their fitment on the page, rather than their note value. I've read the section of the NR on proportional spacing, which does exactly the opposite of what I want. Is there a way to force essentially uniform spacing, regardless of note value? How about this solution? http://lists.gnu.org/archive/html/lilypond-user/2010-08/msg00301.html HTH -- Marek Klein http://gregoriana.sk Gregoriana on youtubehttp://www.youtube.com/playlist?list=PLBQHqmaUgUMZ4Bd4w4heeQF9lV9L7BS-s ___ lilypond-devel mailing list lilypond-devel@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-devel
Re: Bass figures are not horizontally aligned to whole notes
Hello,
2013/2/2 Xavier Scheuer x.sche...@gmail.com
My guess is that bass figures should indeed be centered on the note
heads (note column), so default behaviour should be changed accordingly.
But only the figures. Accidentals, +, etc. should not be taken into
account in the centering, contrary to Bertrand's first workaround.
If someone possessing a reference book could confirm this, thanks.
Could this be considered as the minimal example and the bad output?:

financial support according to The Lilypond Report #24
Hi David, I am willing to support the development of LilyPond financially with small amount of money regularly. I am not sure I understand your payment plans. For example (quoting from http://news.lilynet.net/?The-LilyPond-Report-24): - [*Lifesaver*] Minimum €0, cap €250 per month, monthly target €800. That means that if the target (which basically allows me to postpone my decision to work elsewhere) is reached with everybody’s minimum already, you are not billed. This is the option to pick if you don’t want to support a single person as much as keep the LilyPond project from losing me. You do what is necessary to avoid my leaving, but nothing else. Yes, it will be annoying if it turns out you have to pay the cap more than once, but it will also be annoying for me not even to afford survival in spite of highly qualified work. Does it mean, that people should express their interest to keep the LilyPond project from losing you and you will let them know according to the number of payers how much should everyone each particular month pay?

Re: Lilypond's SVG output
Hello, 2011/8/18 Sandor Spruit a.g.l.spr...@uu.nl Hello, I recently had an informal discussion with some collegues on the use of SVG, in general. They are in music research, I am a developer working on a completely unrelated topic - so please forgive me my ignorance w.r.t. music-related terminology. We discussed the possibilities to use music scores on web pages, and they immediately referred to Lilypond because of its quality output. While browsing this list's archives, and other on-line discussions for that matter, two questions came up: - In what version, exactly, did Lilypond drop the use of groups (svg:g) in its output? I read a debate on this issue, where the key argument against groups was the trouble people have in editing grouped SVG elements in Inkscape. I can, however, imagine all sorts of situations in which group elements could be very useful - from a developer's point of view at least. This leads to the second question: - For what purpose are people putting music up on the web; what's the typical use case? Just publishing it for others to read? Hyperlinking to it, from it? Annotations? Keeping bits and pieces of music for later reference? Learning? Studying? Comparing versions? I may, at some point, be in the position to do some work on this. But I'm hesitant to dive in at the deep end - meaning Lilypond tens of thousands of lines of code ... A bit of guidance might help though :) cheers, Sandor Spruit Information and Computing Sciences, Utrecht University __**_ lilypond-user mailing list lilypond-u...@gnu.org https://lists.gnu.org/mailman/**listinfo/lilypond-userhttps://lists.gnu.org/mailman/listinfo/lilypond-user I can not answer your questions, but maybe developers list is better place to ask... forwarding.

Re: dynamic alignment
Hi Jan-Peter,
2010/12/13 Jan-Peter Voigt jp.vo...@gmx.de
Hello list,
I wrote a script to align dynamics centered on the corresponding note:
--snip--
\version 2.12.3
% calculate x-alignment based on attribute text + dynamic text
#(define-markup-command (center-dyn layout props atr-text dyn)(markup?
string?)
x-align on center of dynamic
(let* (
(text (string-append atr-text ))
(atr-stencil (interpret-markup layout props (markup #:normal-text
#:italic text)))
(dyn-stencil (interpret-markup layout props (markup #:dynamic
dyn)))
(atr-x-ext (ly:stencil-extent atr-stencil X))
(dyn-x-ext (ly:stencil-extent dyn-stencil X))
(atr-x (- (cdr atr-x-ext)(car atr-x-ext)))
(dyn-x (- (cdr dyn-x-ext)(car dyn-x-ext)))
(x-align
(* (-
(/ (+ atr-x (/ dyn-x 2)) (+ atr-x dyn-x) )
0.5) 2)
)
)
(interpret-markup layout props (markup #:halign x-align #:concat
(#:normal-text #:italic text #:dynamic dyn)))
))
% define some dynamics
pocof = #(make-dynamic-script (markup #:center-dyn poco f))
menof = #(make-dynamic-script (markup #:center-dyn meno f))
subp = #(make-dynamic-script (markup #:center-dyn subito p))
% activate X-offset, so that halign works
dynx = #(define-music-function (parser location musik)(ly:music?)
#{
\override DynamicText #'X-offset = #0 $musik \revert DynamicText
#'X-offset
#})
% example %
\new Staff
\relative c'' {
d \dynx c\pocof d e | d\ff d cis eis ~ | \dynx eis1\subp | r4 \dynx
b\menof c\f
}
--snip--
This script first calculates the widthes of the attribute-text (wa) and
the dynamic text (wd), so that I can calculate the right \halign value:
halign = ((wa + (wd / 2)) / (wa + wd) - 0.5) * 2
Then I use a markup with \halign. This works quite well as long DynamicText
#'X-offset is set! If that is set all other dynamics are aligned badly.
So I wrote a little function, that sets and unsets (reverts) that value to
let the halign work.
My question is:
Is it possible to set that value inside the make-dynamic-script or align it
some other way, so that I can simply use my defined \pocof (etc.) without
switching X-offset on and off?
Regards,
Jan-Peter
I can not answer your question, but it is probably better placed on
lilypond-devel (cc-ing).

Re: tracking patches
Hi, I will do it. -- Marek Klein http://gregoriana.sk 2009/10/26 Graham Percival gra...@percival-music.ca Could we get a volunteer to keep track of patches? The idea is that whenever somebody sends a patch, if nobody does anything to it within, say, 3 days, you add it to the google issue tracker. If you already read the mailists, I estimate it will take 1 hour each month. That's not much time to volunteer, but it could make a *huge* difference for new contributors. It's really discouraging when you submit something, nobody replies, and you're left wondering if your email client ate the patch or if everybody hates you or something.

gregorian notation
Hi, I like lilypond very much and use it for writing scores for my choir. I would love to use it for gregorian (square) notation also, but for this lilypond output is simply not satisfiable. It is obvious from examle given in current documentation: http://lilypond.org/doc/v2.11/Documentation/user/lilypond-big-page#Ancient-notation. Comparing with Ideas of lilypond essay http://lilypond.org/web/about/automated-engraving/ there is a big contradiction. There are many issues, as discussed already few times, for example here: http://lists.gnu.org/archive/html/lilypond-devel/2006-03/msg00224.html The main issue IMO is spacing. As Juergen Reuter 32 months ago writes: Right, horizontal spacing is a known issue in Gregorian chant notation in Lily. It has been discussed in the past more than once, though without finding a good and easy-to-implement solution. I can believe, it is not easy at all, but I would like to find a way how to change/improve it. I could offer my time (some little part of it), some amount of money, my knowledge in this area (gregorian chant)... Maybe I could do some coding also, but I don't know python yet and because of complexity of the problem it would definitely require some leading. Where to begin?
