Re: [Denemo-devel] excerpt from selection

[Richard Shann]

I've looked into this: I think we should make the print commands pop up
a dialog under the following conditions

1) Ordinary (pdf) print if there *is* a selection: dialog offers to
print just the selection but the default response (Enter from the
keyboard) is to print the whole music
2) Excerpt print if there is *no* selection: dialog offers to print the
whole file or accept start/end measure numbers and start end staff
numbers (each in range 1+) which sets the selection and then prints the
selection.
Otherwise there should be no dialog, just print, the selection (for
excerpt) or the whole music (for pdf)

To do this:
        exportlilypond.c needs modifying to use   si->markstaffnum,
si->first/laststaffmarked si->first/lastmeasuremarked instead of passed
parameters start,end
the callers of export_lilypond() need modifying (mainly file.c, the
exportpdf.c needs to be retired and the functionality integrated in
print.c where most of the code is duplicated).
Dialogs need writing - there is no function set_selection(firststaffnum,
laststaffnum, firstmeasurenum, lastmeasurenum, firstobjnum, lastobjnum)
but I can create one. (If possible we should pass two pointers to a
bookmark structure rather than separate gints, but that is a detail).

I am happy to handle the lilypond & its callers, Jeremiah would you be
up for the dialog(s) and the exportpdf.c integration/retirement?
