Comment #7 on issue 1015 by percival.music.ca: doc line width
http://code.google.com/p/lilypond/issues/detail?id=1015
Some initial info:
- the docs current set the line width to be 160mm in:
python/book_texinfo.py
(all our manuals use @afourpaper)
This seems very reasonable. A4 paper is narrower (210.0mm) than usletter
(215.9mm), so we should use the narrower version. If we have a 25mm
left+right margin, then this leaves 160mm for the width.
NB: this leaves no space for a gutter. I'm comfortable with that, but I'm
prepared to listen to arguments in favour of gutters.
However, the lilypond line-width is *not* 160mm.
- currently, 3mm is subtracted from this figure. I believe this is to
reserve space for bar numbers.
- we SHOULD (but currently do not) reserve space for instrument names, or
make lilypond automatically shift the music to the right. (this is issue
766 and 1093, which on a quick reading are duplicates? and 766 is lacking
an image)
- we SHOULD (but currently do not) reserve space for [quote].
A clear demonstration of these problems is the snippet
heavily-customized-polymetric-time-signatures.ly. In snippets.pdf, the
music extends into the right-hand page margins. In the HTML output, this
image is 683 pixels wide, whereas other "full-width" images are 639
pixels. (this number must have been chosen deliberately, and IMO is quite
appropriate)
So I think this issue is blocked on the instrument name and (maybe) the bar
number shifting. But the overall effect is that the amount of horizontal
space will be reduced; probably to about 150mm.
