Installing lilypond-book on macOS

lilypond-book is not generally distributed as part of a TeX distribution and most likely you will need to install it. On macOS this can be done most easily with brew by running brew install lilypond on the command line.

Creating a lilypond-book Custom Build Script

As lilypond-book is not by default part of a TeX distributions, the support for it is not built into Texpad. You can however run the typeset from within Texpad by using a Custom Build Script apps/typesetting/typesetters/external/custom-typesetting .

A simple example for lilypond is shown below.

An example Custom Build Script for lilypond-book

 # A Texpad build script to run lilypond-book and generate a pdf

BareName="$(basename $TEXPAD_ROOTFILE_NO_EXT)"

mkdir -p "$TEXPAD_TEMPDIR"
lilypond-book "$TEXPAD_ROOTFILE" --output "$TEXPAD_TEMPDIR/$BareName.lytex" || {
    exit 1
cd "$TEXPAD_TEMPDIR/$BareName.lytex" || {
    echo "fatal: lilypond-book did not generate the output in the expected location"
    exit 1
latex "$BareName.tex"
dvips "$BareName.dvi"
ps2pdf "$" || {
    echo "fatal: ghostscript step failed"
    exit 1
mv "$BareName.pdf" ../..

This is intended as a starting point for simple documents. It is possible that you require further features such as indices, bibliographies, etc that it does not cover and you should extend it for them.

To install the build script please follow the instructions here apps/typesetting/typesetters/external/custom-typesetting#4-local-and-global-scripts . We suggest that you download this script using the button and install it as a Global Build Script. After rebooting Texpad you will be able to use it for any document on your computer.
