Re: Text centralized above a TextSpan

[David Nalesnik]

Hi,

Alright!  This should do it...

You can:

--Adapt this for versions < 2.19.27 with a loss of overriding power (style, dash-fraction, etc.)--see comments beginning in line 435

--Use/mix markups and strings.

--Specify any number of texts >= 2 for your spanner.

--Break it across an arbitrary number of lines, with an acceptable distribution.

--Use spacers ("") to force texts closer/farther apart.  You can also move them like this:

\markup \translate [...]

\markup \right-align [...]

etc.

--Override the number of texts per line if you don't like the automatic distribution.  There's a warning if the numbers don't tally.

--Specify which texts will be joined by a line and which won't using TextSpanner.connectors. I noticed this request in another related thread:

http://www.mail-archive.com/lilypond-user%40gnu.org/msg103939.html

The default is to join everything, and we revert to that with a warning if you specify too few connections. (Full disclosure: you can't hide one half of a line crossing a break and show the other half, but unless there's some pressing need, I'm going to forget I noticed this....)  

--Change the distance from text to line with TextSpanner.line-offset, which defaults to #'(0.0 . 0.0).

Additionally, there are warnings for overlaps.  There's no attempt at fixing these.  I wouldn't know how to influence spacing.

By the way, is there a way to get spacing to accommodate really long left/right texts with ordinary TextSpanners without resorting to \newSpacingArea, manual breaks, and the like?  I don't find a mechanism: \textLengthOn doesn't seem to work...

Enjoy--

David

P.S.  One area of further improvement would be the input syntax.  Any suggestions for making this more user-friendly?  I can't figure out how to get markups to process properly without that off-putting

#(list #{ \markup "foo" #} )

construction.
