Openlilylib snippets announcement

[Andrew Bernard]

Hello All,

 

Just letting you know that I have contributed some snippets to openlilylib worth having for doing some small things in contemporary style scores, but which need some Scheme coding.

 

Slashed beams

 

A function \slashBeam that can add a slash to the left or the right of a beamed group, with a fair degree of control over angle and position. This is a generalisation of work that others have created previously, in particular it extends the concept of \slash.

 

Slashed stems

 

The function \slashStem allows you to add a slash to a stem with a fair degree of control over position and angle. Note that this is a different case from slashing a beamed group. [There may be arguments against this but I wanted a separate function.] I developed this to make horizontal stem slashes, but it was easy to generalize.

 

Pedal decorations

 

People have often requested to be able to add cautionary labels to pedal brackets on continued lines. There have been many workarounds given. This solution in Scheme attacks the problem directly by modifying the bracket stencil. An arbitrary text label can be added, and optional continuation arrows can be added to the right hand end of the bracket. This style is commonly seen in contemporary scores.

 

These three new capabilities can be found under snippets/notation-snippets in the openlilylib repository.

 

If there do not exist bugs and defects I would be surprised. I am happy to take feedback and suggestions. The code is for the >= 2.19.45 releases. I have not tested on 2.18.2, and unless somebody requests, I don’t intend to.
