Slur with two turning points

2026-03-13T18:14:19Z

SimonAlbrecht: Update OLL link

A slur normally can only have one turning point. In special situations, one may need two or more turning points, however. This can be achieved by linking two (or more) slur stencils together. The control points need to be specified manually: for two segments this is a set of seven points, of which the fourth is shared by both segments. To ease working with the function, the control points are shown as light blue crosses if the second argument is ##t.<br />
For a more refined solution to the problem, see [https://github.com/openlilylib/snippets/tree/master/notation-snippets/compound-slurs Shaping Bezier Curves], needing version 2.19.48 or higher.

== Bitte LilyPond-Version beachten! ==

Danke für das Update von [[Adjusting vertical positioning of lyric hyphens]]! Allerdings mußte ich deine Änderungen teilweise wieder rückgängig machen, weil Du Syntax verwendet hast, die es in 2.24 noch nicht gibt. Wenn möglich, verwende bitte nichts neueres als 2.24 in diesem Wiki. Falls neueres demonstriert werden soll, muß die Versionsnummer in <code><lilypond></code> angepaßt werden. -- [[User:Lemzwerg|Lemzwerg]] ([[User talk:Lemzwerg|talk]]) 06:06, 28 February 2026 (UTC)

:Oh, das war natürlich ein handwerklicher Fehler. Ich bin gerade nicht mehr sicher, ob ich gar nicht an 2.24 gedacht hatte oder ob ich dachte, das wäre da schon drin gewesen. So oder so danke fürs revidieren! [[User:SimonAlbrecht|SimonAlbrecht]] ([[User talk:SimonAlbrecht|talk]]) 09:50, 28 February 2026 (UTC)
:Wäre es sinnvoll, die <code>property-defaults</code>-Syntax als Kommentar drin zu lassen für das Update zu 2.26? [[User:SimonAlbrecht|SimonAlbrecht]] ([[User talk:SimonAlbrecht|talk]]) 09:53, 28 February 2026 (UTC)

Adjusting vertical positioning of lyric hyphens

2026-02-26T13:20:27Z

SimonAlbrecht: Major syntax update, code formatting

For joining syllables, LilyPond doesn’t use the hyphen of the text font but instead draws a simple line with variable length (this limitation is tracked as {{Issue|1255}}). Its standard vertical position doesn’t always fit the proportions of the text font. When using a font with a large x-height, it may be too low.

You can adjust the vertical positioning of the hyphens manually. To get a good result you may want to insert a “real” hyphen for comparison (like between l-e in the snippet).

Separating footers with a horizontal line

2026-02-26T12:21:45Z

SimonAlbrecht: remove spurious comment, add new comment for documentation

Separating footers from the main content of the page using a horizontal line can be done by altering the <code>oddFooterMarkup</code> paper variable (and <code>evenFooterMarkup</code>, if they should be different). However, this requires printing the horizontal line only if any footer is shown on that page; this snippet demonstrates how to program such a condition.
