Here is an approach to this issue: create an HTML document that includes
each SVG.
In which case, you don't need to embed the script in the SVG, you can link
it once in the HTML file:
Here is the MWE
% lily-easy-slurs.ly
\version "2.19.45"
\include "lily-easy-slurs.ily"
figure = \relative c' { g4_\( a' b2 ~ | \noBreak 2 ( e8 d ) c,4 \) | }
{ \figure \pageBreak \figure }
Here is the script to run lilypond on the MWE, then create an HTML file
that includes all the SVGs, and open it:
#!/usr/local/bin/bash
# Usage: buildLilyEasySlurs.sh file-base-name
FILE_BASE_NAME="lily-easy-slurs"
if [ "$1" != "" ]; then
FILE_BASE_NAME=$1
fi
LILYPOND="$FILE_BASE_NAME.ly"
HTML="$FILE_BASE_NAME.html"
rm "$FILE_BASE_NAME*.svg"
lilypond -dbackend=svg $LILYPOND
echo "<html>" > $HTML
echo "<head><title>Editing Lilypond curves</title>" >> $HTML
echo "</head>" >> $HTML
echo "<body>" >> $HTML
for SVG in `ls -1 $FILE_BASE_NAME-*.svg`; do
echo "SVG is $SVG"
echo "" >> $HTML
cat $SVG >> $HTML
done
echo "" >> $HTML
echo "<script src="lilyEasySlurs.js"></script>" >> $HTML
echo "</body>" >> $HTML
echo "</html>" >> $HTML
echo "" >> $HTML
open -a "Google Chrome" $HTML
