Re: lilypondbook with multiple files

[Susan Dittmar]

Dear Stefan,

looks like lilypond-book does not honor the \input command, which means you
will have to process those parts one by one. I would even appreciate this
behaviour if my assumption is correct, as it reduces the workload for
lilypond in case of changes in only one of the part files.

I did not work with lilypondbook yet, but I would try this approach:

- move partone.tex to partone.lytex
- move parttwo.tex to parttwo.lytex
Do *not* change the \input calls in master.tex!

When processing the main document, you'd have to

- process partone.lytex:
  lilypond-book --pdf partone.lytex
  (I removed the output directory as I suspect that would raise new
  problems for TeX. They can be solved, but I want to keep this one
  simple. Once it works we can try to re-introduce that.)
  Do *not* pdflatex that part, as it is no complete document!
  If I understand correctly, it generates a file partone.tex.
- process parttwo.lytex:
  lilypond-book --pdf parttwo.lytex
- Now process the main document. As it does not include any lilypond
  code, no lilypond preprocessing is necessary. So you only need to
  run it through the TeX engine:
  pdflatex master.tex

This can be done using the 'make' command and a Makefile like this (replace
the <tab> by true tab keystrokes; they are important!):

#### Makefile begin #############

default: master.pdf

master.pdf: master.tex partone.tex parttwo.tex
<tab>pdflatex master.tex

.SUFFIXES:
.SUFFIXES: .lytex .tex

.lytex.tex:
<tab>lilypond-book --pdf $(basename $(notdir $@)).lytex

#### Makefile end ################

Unfortunately I do not have a running lilypond at the moment, so all this
is untested.

Hope it helps nonetheless,

        Susan

PS: If you have any questions about what the individual commands do or
    mean, feel encouraged to ask!
