In the NR in Section 7.4.4
(http://lilypond.org/doc/v2.11/Documentation/user/lilypond/New-markup-list-command-definition
)
there is a definition of the \paragraph markup list command, which
indents
the first line by the value of the property 'par-indent. There is
also an
example how to override that property to a different value, but
apparently
the \override-lines macro works like \once\override and not like
\override,
i.e. it works only for the very next call of \paragraph, but not for
subsequent calls.
This also means that I cannot globally change the indentation of the
paragraphs (except changing the hard-coded default in the
definition, which
is not what I want, because the definition is in an external style
sheet,
included by multiple different scores with different formatting
styles).
So, how can I globally change a property like par-indent or line-
width?
With the following definition of the \paragraph command, you can
globally change the indentation by setting a paper variable at
top-level:
#(define-markup-list-command (paragraph layout props args) (markup-
list?)
(let ((indent (chain-assoc-get 'par-indent props
(ly:output-def-lookup layout 'par-indent 2))))
(interpret-markup-list layout props
(make-justified-lines-markup-list (cons (make-hspace-markup
indent)
args)))))
\paper { par-indent = #3 }
