music21.lily.lilyObjects

music21 translates to Lilypond format and if Lilypond is installed on the local computer, can automatically generate .pdf, .png, and .svg versions of musical files using Lilypond

this replaces (April 2012) the old LilyString() conversion methods.

The Grammar for Lilypond comes from http://lilypond.org/doc/v2.14/Documentation/notation/lilypond-grammar

LyAssignment

class music21.lily.lilyObjects.LyAssignment(assignmentId=None, identifierInit=None, propertyPath=None, embeddedScm=None)

one of three forms of assignment:

assignment_id ‘=’ identifier_init assignment_id property_path ‘=’ identifier_init embedded_scm

if self.embeddedScm is not None, uses type 3 if self.propertyPath is not None, uses type 2 else uses type 1 or raises an exception.

>>> lyIdInit = lily.lilyObjects.LyIdentifierInit(string='hi')
>>> lya = lily.lilyObjects.LyAssignment(assignmentId='title', identifierInit=lyIdInit)
>>> print(lya)
title = "hi"

Note that you could also pass assignmentId a LyAssignmentId object, but that’s overkill for a lot of things.

Note that if any LyEmbeddedScm is found in an output then the output SHOULD be marked as unsafe. But a lot of standard lilypond functions are actually embedded scheme. For instance, clef, which as http://lilypond.org/doc/v2.12/input/lsr/lilypond-snippets/Pitches#Tweaking-clef-properties shows is a macro to run a lot of set commands.

LyObject read-only properties

LyObject.newlineIndent

Read-only properties inherited from ProtoM21Object:

LyObject methods

LyObject.ancestorList()

returns a list of all unwrapped parent objects for the current object

LyObject.comment(stringIn: str) → str

returns a comment that is %{ stringIn.strip() %}

(Don’t put %} etc. in comments – it will break the system.)

LyObject.encloseCurly(arg)
LyObject.getAncestorByClass(classObj, getAncestorNumber=1)
LyObject.getFirstNonNoneAttribute(attributeList)
LyObject.getParent()
LyObject.newlineSeparateStringOutputIfNotNone(contents)
LyObject.quoteString(stringIn)

returns a string that is quoted with internal quotation marks backslash’d out and an extra space at the end.

>>> m = lily.lilyObjects.LyObject()
>>> print(m.quoteString(r'Hello "there"!'))
"Hello \"there\"!"
LyObject.setAttributes(m21Object)

Returns a dictionary and sets self.lilyAttributes to that dictionary, for a m21Object of class classLookup using the mapping of self.m21toLy[classLookup]

>>> class Mock(base.Music21Object):
...     pass
>>> m = Mock()
>>> m.mockAttribute = 32
>>> m.mockAttribute2 = None

>>> lm = lily.lilyObjects.LyMock()

LyMock (our test class) defines mappings for two classes: to LyMock.lilyAttributes:

>>> print(lm.supportedClasses)
[...'Mock', ...'Mocker']

Thus, we can get attributes from the Mock class (see setAttributesFromClassObject):

>>> lilyAttributes = lm.setAttributes(m)
>>> for x in sorted(lilyAttributes.keys()):
...    print(f'{x}: {lilyAttributes[x]}')
mock-attribute: 32
mock-attribute-2: None

>>> lilyAttributes is lm.lilyAttributes
True
LyObject.setAttributesFromClassObject(classLookup, m21Object)

Returns a dictionary and sets self.lilyAttributes to that dictionary, for a m21Object of class classLookup using the mapping of self.m21toLy[classLookup]

>>> class Mock(base.Music21Object): pass
>>> m = Mock()
>>> lm = lily.lilyObjects.LyMock()

LyMock (our test class) defines certain mappings from the m21 Mock class to LyMock.lilyAttributes:

>>> for x in sorted(lm.m21toLy['Mock'].keys()):
...    print(f"{x}: {lm.m21toLy['Mock'][x]}")
mockAttribute: mock-attribute
mockAttribute2: mock-attribute-2
