Discuss the alignment of scores in text documents

[Urs Liska]

Hi all,

I have finally managed to check out Jacques Peron's lyluatex package 
(https://github.com/jperon/lyluatex), and I got my first pull request 
merged. I'm totally thrilled about this tool and the possibilities for 
authoring music documents. Essentially it's lilypond-book without the 
hassle of having to use a preprocessor (and deal with cluttered document 
directory or path issues. (Of course it's far from complete, but one 
definitely can see the potential). Now I can finally maintain the scores 
to be used in text documents as LilyPond code (in the .tex file or in 
separate include files) and don't have to worry about keeping them 
up-to-date or updating all examples when something in the layout of the 
text document changes! Even more spectacular will it be when all that 
works smoothly with Pandoc - allowing to author documents in Markdown 
and still have immediate access to LaTeX and LilyPond for automatic 
typesetting.

My first contribution was allowing scores to be aligned to the paragraph 
so that the *staff lines* match the paragraph while margin stuff like 
braces or instrument names protrude into the left margin. It's exciting 
to see that at work automatically - and think back at the days when I 
had to live with inconsistently scaled score examples or tedious 
trial&error formatting.

However, this first success implies the need for further discussion in 
order to continue development. For this I have prepared a PDF that 
demonstrated the feature and discusses the current question. This is 
uploaded as part of the issue https://github.com/jperon/lyluatex/issues/36.

There are questions specific to the use of a LaTeX package but also 
general typographic ones, so everyone on this list could have valuable 
opinions. I would be happy about feedback, but as I will ask other 
communities as well it would be good to concentrate discussion to the 
Github tracker as much as possible.

Best
Urs
