Re: Defining custom symbols

[Andrew Bernard]

Hi Robert,

Hmm. I have played around with this a bit. I think if you are using safe
mode of necessity then you simply can't use lilypond for this use case.
Sooner or later you have to mix Lilypond and Scheme, and it is forbidden in
safe mode.

Transforming the code for the cut from the repo in question, I came up with
this:



\version "2.19.81"


#(define larsenSymbolsOutlineWidth 0.065)
#(define larsenSymbolsScale 1.5)
#(define larsenSymbolsOutlineWidth 0.065)

#(define larsenSymbolsHalignFactor (+ (* larsenSymbolsScale ( / 2 3 ) ) .15
))
#(define larsenSymbolsHalfSize (* .5 larsenSymbolsScale))
#(define larsenSymbolsFlipVertical (* -1 larsenSymbolsScale))

cutCoordinates =   #'(
   (.4 .9)
   (.55 .825)
   )

cutStencil =
\markup \halign #(/ -3 larsenSymbolsHalignFactor) \stencil
#(make-connected-path-stencil
  cutCoordinates
  larsenSymbolsOutlineWidth
  larsenSymbolsScale
  larsenSymbolsScale
  #t
  #t
  )

#(append! default-script-alist
   (list
`("cut"
   . (
   (text . ,#{ \cutStencil #})
   (stencil . ,ly:text-interface::print)
   ; any other properties
   (toward-stem-shift-in-column . 0.0)
   (padding . 0.20)
   (avoid-slur . around)
   (direction . ,UP)

%cut = #(make-articulation "cut")
#(define cut (make-articulation "cut"))

test = {
  \time 2/4
  c''2\cut
  c''
  c''\cut
}

\score {
  \new Staff \test
}


But under safe mode Guile throws errors, in accordance with the NR
statements.

At this point, we need to turn to greater experts than me. I am sure that
my posting this weak code above will stimulate somebody of greater
knowledge to show if this really is possible.

In the meantime, the set of Larsen ornamentation glyphs is a really nice
library if one is using it in a 'normal' context.

Re: Defining custom symbols

[Andrew Bernard]

Hi Robert,

I myself have never used safe mode, but according to the NR:

It is also not possible to import LilyPond variables into Scheme while in
safe mode.

Therefore the present code will not work as written. I'll take a look at it.

Strongly recommend using 2.19.81, especially if I am going to help you out
extending this symbol code library. The wording of unstable on the website
is open source over modesty, a conventional trope. The latest releases are
very stable, and I bang away at them all day on very very complex scores
and even I cant crash them. There are lots of new features in the 2.19
series that I cannot imagine not wanting to have.

The Ubuntu repo is stuck at the nominated stable release. Just download
from lilypond.org.

Re: Defining custom symbols

[Robert Hickman]

I'm trying to set the page size so that it automatically
matches the size of the staff with zero margins. Looking
at the documentation on this shows the following command,

but I cannot see how to set it to scale 'as big or small
as needed'. The section on automatic scaling isn't clear
as this appears to relate to internal operation of the software,

not to automatically scaling the size of the page..


#(set-default-paper-size "quarto")

Attached is what I'm currently getting, with a large amount

of empty space.

That means: yes, you can prohibit the use of \include and instead include some 
(safe) code before it even reaches LilyPond.

Thanks, -dsafe looks like the simplest to use but 'In addition, safe mode
disallows \include' which I need to use the symbol file. Is it sufficient
to concatenate the symbol file at the beginning of the user code?

Re: Defining custom symbols

Hi Robert,

I cloned the git repository and compiled the Larsen symbols. I all works
beautifully with the current highest revision of lilypond 2.19.81, even
though the code is somewhat old.

Here's the result of the test code attached as an image.

The code fr this is not hard to understand:



\version "2.19.81"
\include "larsen-symbols.ily"

  \time 2/4
  {

b'2\cut
b'\strike
b'\slideUp
b'\slideDown
b'\longRoll
b'\shortRoll
b'\longDoubleCutRoll
b'\shortDoubleCutRoll
b'\crann
b'\shortCrann
b'\trill
b'\singleTrill
b'\shake
b'\breathe
  }



I'd really recommend you go with lilypond as it is incredibly powerful -
witness this extension as an example - and it does not take long to learn
the basics.

Re: Defining custom symbols

[Andrew Bernard]

Hi Robert,

Using a font is not how this is done in lilypond. It's a matter of defining
new symbols that can be used by the engraver modules for the notes, like
articulations and so on. This is fairly advanced to build from scratch, but
you can just use the results of the work I pointed to as a type of library,
without having to know all the low level details.

Looking for a font with Irish symbols is not the way to go.

Andrew
