Overview

A namespace for LilyPond-notation parsing helpers

Defined Under Namespace

Modules: StringText Classes: AssignmentReader, BookWriter, ContextReader, Document, DocumentReader, DurationReader, DurationWriter, FlowBuilder, KeyMapper, KeyReader, Lexer, MeterReader, MusicItemReader, MusicReader, ParseError, ParsePreflight, Parser, PitchReader, PitchReaderStack, PitchWriter, Preflight, RenderError, RenderPlan, SourceScanner, Token, TokenCursor, UnsupportedFeatureError, VoiceContext, VoiceStream, VoiceWriter, Writer

Constant Summary collapse

ENVELOPE_COMMANDS = The commands that wrap a document rather than appear in its music. The DocumentReader dispatches on them; the MusicReader rejects them.

Class Method Summary collapse

.parse(lily_pond_string) ⇒ Object
Interprets a LilyPond document, or a bare music expression, as a flow.
.render(flow, **options) ⇒ Object
transposed: says the flow's pitches are already the written ones, so that each part prints its own key and a \transposition naming what it sounds.

Class Method Details

.parse(lily_pond_string) ⇒ `Object`

Interprets a LilyPond document, or a bare music expression, as a flow. Raises before building on anything outside the supported subset, so callers never receive a partial flow.
