Re: fondu fails on newer OS X versions

[padovani]

Hello,

it seems that I'm having the mentioned fondu issue while running LilyPond
2.19.80 on OSX 10.11.6 - El Capitan.
[
http://lilypond.1069038.n5.nabble.com/fondu-problems-on-El-Capitan-td189203.html
]

Is there a fix around? Digging the LilyPond user, developer and bug lists I
didn't found the fix, although someone mentioned a patch.

Thank you very much for any help on this
José H.

Not sure if it was already mentioned...

just installed 2.17.17 and it seems that the new (and nice!) angled hairpins are
not compatible with the circled tip:

\once \override Hairpin #'circled-tip = ##t %%doesn't work
\once \override Hairpin #'stencil = #flared-hairpin
g4\< ~ g4 ~ g8\f

Re: exponential crescendo... / Mike "experimental" spanners?

[padovani]

Thank you Janek... sorry to post it in the wrong place.

Well...
If this issue means to change something in circled-tip definition, I think
that it would be nice to have a second type of dal niente/al niente.
If I remember correctly, circled-tip was hard-coded in C - away from my
hacking capabilities.

Maybe it would be better to define it in scm files with path, so that one
could use other styles of dal-niente/al-niente.

As an example, I prefer very much something like a slashed-circle (messy
example, sorry):

%%code
slashflag = \markup{\combine \translate #'(-0.3 . -0.3) \draw-line #'(0.6 .
0.6)
\fontsize #-5 \musicglyph #"scripts.flageolet"}
nientedyn = #(make-dynamic-script slashflag)

\relative c' {
%\once \override Hairpin #'circled-tip = ##t
\once \override Hairpin #'stencil = #flared-hairpin
\once \override Hairpin #'bound-padding = #0
%\once \override Hairpin #'bound-details #'left #'padding = #0 %% <- this
feature would be nice, just as in Glissandos...
g'2\nientedyn\< ~  g8\fff
}
%%end of code

Does anyone know a trick to slash the circled-tip option of Hairpins?

I think the problem is that the wrapper app *only* works on Leopard.
IIRC, there were reports of it not working on 10.4.

The link for Leopard on the LilyPond download page points to a page 
(ivo.bouwmans.name/lilypondleopard) that I set up for 2.10.


I have just tried both lilypond-2.12.0-1.darwin-x86 and 
lilypond-2.12.0-1.darwin-ppc from 
. Both versions only show one 
menu without any items when run as application (the same as with 
2.10). But both work fine when used in Terminal - and the x86 version 
is faster, as can be expected.


I will change the page so that Mac users will be directed to the x86 
version, with the option of using my LilyPondScript.


If anyone has additional ideas: please let me know!

svg font issue(bug?): can't change TimeSignature font (but markup fonts can be changed)

[padovani]

Hi,

This code compiles on .ps /.svg backends without problems:

%code 1
\score {
\new Staff {
\time 2/4
c2_\markup {
  \override #'(font-name . "Helvetica")
"here it works"
}
}
}
%end code 1

But the code below one gives me an error if I compile with -dbackend=svg

%code2
\score {
\new Staff {
\override Staff.TimeSignature.font-name = #'"Helvetica"
\time 2/4
c2_\markup {
  \override #'(font-name . "Helvetica")
"here it works"
}
}
}
% end code 2

here is the error:
%%error begin
Interpreting music...
Preprocessing graphical objects...
Finding the ideal number of pages...
Fitting music on 1 page...
Drawing systems...
Layout output to `teste.svg'...
warning: cannot find SVG font #f

%%error end

(I'm using 2.19.19 on OSX 10.9.5.)

Is this a bug? It seems that something need to be changes in
output-svg.scm... any idea?

Re: svg font issue(bug?): can't change TimeSignature font (but markup fonts can be changed)

[padovani]

So... I discovered that the TimeSignature issue is related to the fact that
it is not being written as text to the svg file, but as a path.

If I use this code I can create a svg file with different fonts for the
time signature, overriding the stencil with a text:

%% BEGIN CODE 1
\score {
\new Staff {

\once \override Staff.TimeSignature.stencil = #ly:text-interface::print
  \once \override Staff.TimeSignature.text = \markup {
  \override #'(font-name . "Helvetica")
  \override #'(baseline-skip . 0.2)
  \fontsize #4
 \column { "3"
   "4"
  }}
\time 2/4
c2
}
}
%% END CODE 1

It works, but I'm struggling here to change the text of the time signature
automatically with a scheme function. Tried the code below, but it does not
work (giving me exactly the same error dump of my previous message). Any
suggestions?

%% BEGIN CODE 2
#(define-public (tsigastext grob)
   (let* ((frac (ly:grob-property grob 'fraction))
  (num (if (pair? frac) (car frac) 4))
  (den (if (pair? frac) (cdr frac) 4))
  (m (markup
  #:override '(font-name . "Helvetica")
  #:override '(baseline-skip . 0.5)
  #:fontsize 4
  #:center-column (#:number (number->string num)
   #:override '(style . default)
   #:number (number->string den)
 
(ly:grob-set-property! grob 'stencil ly:text-interface::print)
(grob-interpret-markup grob m)))


\score {
\new Staff {

  \override Staff.TimeSignature.stencil = #tsigastext
\time 2/4
c2


%%% \override Staff.TimeSignature.stencil = #(lambda (grob)
%%%(parenthesize-stencil (ly:time-signature::print grob) 0.1 0.4 0.4
0.1 ))

\time 3/4
c2
}
}
%% END CODE 2

thanks!

but if no solution rises up, a bug report seems appropriate.

just found that it just happens with Texier fonts... (my own fonts work

Maybe it is something specific with his fonts?

use guile to set specific extra-offset values if stem direction is up or down

[padovani]

Hello,

I'm dealing with special noteheads I've designed and I need to move the 
stem and the flag differently if stem direction is up or down.


I would like to create a guile lisp clause that sets the extra-offset 
value accordingly to the Stem position.


I was trying this, but it does not work...

\once \override Stem #'extra-offset = #(if (eqv? ly:stem::calc-direction 
UP) '(-0.02 . -0.25) '(0.02 . 0.25))


(also tried this...
\once \override Stem #'extra-offset = #(if (ly:dir? 
ly:stem::calc-direction UP) '(-0.02 . -0.25) '(0.02 . 0.25))

)

any tips?

thanks

Hello David,

thank you very much!

Now I see that ly:stem::calc-direction only gives me the standard Stem 
direction, but if I am using some \stemDown or \stemUp before the note, 
the lambda function will ignore the actual direction of the Stem and 
adjust stem offsets accordingly to the standard direction.


Do you (or anybody else) know a way to access the actual direction of 
the Stem?

Re: use guile to set specific extra-offset values if stem direction is up or down

[padovani]

Hi again,

so.. as the flags are now separate objects (2.15.38), I'm having 
problems to move them to the same place that I am moving the stems... if 
I just reproduce the lambda function I am using with Stems with flags, 
it does not work...


\once \override Stem #'extra-offset =
#(lambda (grob)
 (if (eq? (ly:grob-property grob 'direction) UP)
  '(-0.02 . -0.25) '(0.02 . 0.25)))

%this fails
\once \override Flag #'extra-offset =
#(lambda (grob)
 (if (eq? (ly:grob-property grob 'direction) UP)
  '(-0.02 . -0.25) '(0.02 . 0.25)))

So, is there a way to know the Flag direction? Or maybe a wat to access 
the Stem's grob from the Flag one (so that I can point the function to 
the Stem properties?).


Thank you again,

José

emacs lilypond-mode.el and lilypond-init.el patches to process .lytex files with "lilypond-book --pdf"/"pdflatex"

[josé henrique padovani]

Hi,
I have made some changes on my emacs lilypond-mode files to process 
lytex files as suggested here 
(http://lilypond.org/doc/v2.13/Documentation/usage-big-page#Invoking-lilypond_002dbook)... 
directly with: "lilypond-book --pdf file.lytex" and "pdflatex file.tex"


I'm sending the patches... Please tell me if it is ok (don't know if the 
shortcuts are ok to other people, for example)



I would also like to know if it would be possible to have an option, 
when compiling LilyPond, to change some system specific commands that 
are in lilypond-mode...

For example, for OSX:
"xpdf" -> "open"
"timidity" -> "open"
etc..
(OSX's "open" uses the system default app to read pdf/play midi files)


I have no idea about how to do it as I am a "newbie" in LilyPond 
development..
maybe creating a system specific file lilypond-mode-osx.el would be the 
easier way?


Thanks,
josé

PS: .lytex extension was added to lilypond-init to load lilypond-mode 
automatically as (I think) that latex \include can be used to organize 
files .. and those files with lilypond code need more the ly syntax 
colorizing than tex colorizing...

I do this too on my own lilypond-mode.el..
I meant to have some mechanism to generate "ready-to-use" .el file for

-dbackend=svg ... warning: missing stencil expression `embedded-ps'

[josé henrique padovani]

(OBS: I'm writing to user and devel lists as I am not sure if it is a 
bug...)


Hello,

I am trying to generate svg files of my score, where I use some 
\postscript markups. Everything goes ok, except those markups...

I get this warning and the svg file comes without the postcript drawings...
"warning: missing stencil expression `embedded-ps'"

Is this a bug? If not, is there some work-around?

Thanks
josé

It's not a bug.  :-)

The \postscript command is one of the few commands that uses native
PostScript code in the output.  Since SVG doesn't support embedded
PostScript, there is no easy way to support \postscript in the SVG
backend.

If your PostScript code is simple enough, you could try trying
creating custom figures with the 'embedded-svg routine.  This permits
entering native SVG code that can be used with the SVG backend.  For
an example, see this code:

   http://uoregon.edu/~pmccarty/svg/src/embedded-svg/embedded-svg.ly

Note that 'embedded-svg will not work with the PostScript/PDF output.

Another option is to use the 'path routine.  This isn't documented yet
and is a little cumbersome to use, but you can find an example that
uses 'path in this snippet:

   http://lsr.dsi.unimi.it/LSR/Item?id=623

In other words, there is no *easy* workaround... yet.

-Patrick

   

Thank you for the tips Patrick... (I'm new to lilypond with svg...)
I will take a look on the path routine.

Store values in a scheme variable to use after

[josé henrique padovani]

Hi... I'm trying to store a NoteHead's position (by using scheme 
functions) to be abble to use this value after (as a string in a markup)...
To do that I define a variable (myvar with the string "init") and then I 
use tweak to set! myvar to its new value...


But when I call myvar from a markup, it still finds the old argument 
"init"...


Why?
Is it possible to do something like what I am trying to do in another way?

Thank you,
josé

code:
\version "2.13.22"

#(define myvar "init")

#(define (notehead-get-staffposition notehead)
   ;; notehead is grob
   (ly:grob-property notehead 'staff-position))

#(define (change-myvar notehead)
   ;; notehead is grob
   (let ((sp (ly:number->string (notehead-get-staffposition notehead
 (format #t "~2&~a\n" (make-string 40 #\-))
(begin
 (format #t "~a\n" sp)
 (set! myvar sp

\relative c' {
  c1^\markup{\text \myvar}

  \once \override NoteHead #'before-line-breaking = #change-myvar
  c
  g^\markup{\text \myvar}
  a^\markup{\text \myvar}
}

scheme function to extract a specific grob property from a music event?

[josé henrique padovani]

Hi,

I have tried to find in the manual and in the sources a scheme function 
that let me extract a specific grob from a music object...
I want to be able to know which is the 'staff-position (or should it be 
Y-offset?) grob-property of the notehead I am creating and use it to set 
the Y-offset of my markup.



As my last attempt storing and resetting scheme variables didn't worked, 
I'm following Mike Solomon suggestion and I have created a scheme 
function which writes everything I need...


Here is what I have until now
The function has four entries: event-chord(music?) txt(markup?) 
numx(number?) numy(number?)
What I want to do is to eliminate the last argument by setting it to be 
equal to the same 'Y-offset (or 'staff-position, it is not clear to me 
yet) of the notehead



 CODE BEGIN
myfunction = #(define-music-function (parser location event-chord txt 
numx numy)

   (ly:music? markup? number? number?)
   (let ((result-event-chord (ly:music-deep-copy event-chord))
 (tscript-outside-staff-priority (make-music ;;\override 
TextScript #'outside-staff-priority = ##f

  'ContextSpeccedMusic
  'context-type
  'Bottom
  'element (make-music
'OverrideProperty
'pop-first
#t
'grob-property-path
(list (quote outside-staff-priority))
'grob-value
#f
'symbol
'TextScript)))
 (tscript-xoffset (make-music ;; \override TextScript 
#'X-offset = numx

   'ContextSpeccedMusic
   'context-type
   'Bottom
   'element
   (make-music
'OverrideProperty
'pop-first
#t
'grob-property-path
(list (quote X-offset))
'grob-value
numx
'symbol
'TextScript)))
 (tscript-yoffset (make-music   ;  \override TextScript 
#'Y-offset = numy

   'ContextSpeccedMusic
   'context-type
   'Bottom
   'element
   (make-music 'OverrideProperty
'pop-first
#t
'grob-property-path
(list (quote Y-offset))
'grob-value
numy
'symbol
'TextScript
(set! (ly:music-property result-event-chord 'elements)
 (cons (make-music 'TextScriptEvent 'text (markup txt)) ;;;my 
markup

  (ly:music-property result-event-chord 'elements)))
(make-music 'SequentialMusic 'elements (list 
tscript-outside-staff-priority tscript-xoffset tscript-yoffset 
result-event-chord


\score{
\relative c'{
%{
%\displayMusic
{
 \override TextScript #'outside-staff-priority = ##f
 \override TextScript #'X-offset = #2
 \override TextScript #'Y-offset = #0
 g'1-\markup{"<-"}
}
%}

\myfunction g'1 \markup{\sans "<-"} #2 #0
}
}

cap in path routine (was: Re: Eyeglasses (was Re: -dbackend=svg ... warning: missing stencil expression `embedded-ps'))

[josé henrique padovani]

Just to be sure: Is it possible to set different caps with the path 
routine? (I didn't found this option)
If not, would it be possible to add an optional variable to set it and 
have it working on both ps and svg backends?


thanks

Looking into this more, I see two issues:

1) What names should we use for the different linecap options?
2) Where should these values be specified?

For 1), we could use the PostScript naming convention, though it is
somewhat difficult to remember.  The SVG naming convention is easier
to understand, but more wordy.

For 2), I don't really know at the moment.  :-)

I think it would be best to find a "general" solution that will work
for all routines capable of supporting linecap settings (for example,
'draw-line and 'polygon).

Any thoughts (about syntax, or otherwise)?

Thanks,
Patrick

   
well.. I think that would be good to preserve the ps-like words (simply 
to avoid confusion between svg and

ps syntaxes)

It would be nice to add both "setlinecap" and "setlinejoin" to the 'path 
defs...
They could be added as optional arguments (not sure about the guile 
syntax as I am more


(use-modules (ice-9 optargs)) ;; is this module already loaded by LilyPond?
(define* (path thickness exps #:optional cap join )

 ...)

or, using keywords (more elegant?)... and then if linecap or linejoin 
are not supplied
by the user they can have their actual default values... (maybe path 
could be extendend in this way?)


(use-modules (ice-9 optargs)) ;; is this module already loaded by LilyPond?
(define my-proc (lambda* (thickness exps #&key linecap linejoin)


What do you think?

It's not really time yet to disseminate amongst the Lilypond users, but I
will keep you posted. It has been my personal wish to have this since 2006
(go figure how long it takes to understand how syntax colouring works).

One special request: is there a list full list of Lilypond keywords and
functions available in XML or asci? Going through the manual and copy
pasting is too much for me.

Can you make the syntax keywords and functions avalaible to me as a list so
I can finish up the syntax colouring?


 
The emacs extension has a file "lilypond-words.el" which lists these 
words... maybe it is easier to copy them from there.
