I post-process the midi files from LP because the default names don't
sort correctly. Simply put, I insert "-00" into the first, then "0"
into the next nine single-digit files. After that, the default filenames
will now sort into the correct position. This process is done on each
bookpart independently, if they exist, by spotting the first file in
each sequence:
MIDI output to `adeste-choir.midi'...
MIDI output to `adeste-organ.midi'...
MIDI output to `adeste-organ-1.midi'...
MIDI output to `adeste-organ-2.midi'...
MIDI output to `adeste.midi'...
MIDI output to `adeste-1.midi'...
MIDI output to `adeste-2.midi'...
MIDI output to `adeste-3.midi'...
MIDI output to `adeste-4.midi'...
gets turned into:
adeste-choir-00.midi
adeste-organ-00.midi
adeste-organ-01.midi
adeste-organ-02.midi
adeste-00.midi
adeste-01.midi
adeste-02.midi
adeste-03.midi
adeste-04.midi
However, if you print a distinguishable string whenever you create
a midi file, it would be a relatively simple matter to rename each
midi filename to each respective string:
New name for MIDI file:Adeste fideles congo.mid
New name for MIDI file:Adeste fideles organ.mid
New name for MIDI file:Adeste fideles right.mid
New name for MIDI file:Adeste fideles left+pedal.mid
New name for MIDI file:Adeste fideles descant.mid
New name for MIDI file:Adeste fideles soprano.mid
New name for MIDI file:Adeste fideles alto.mid
New name for MIDI file:Adeste fideles tenor.mid
New name for MIDI file:Adeste fideles bass.mid
The challenge for my doing this without using bash arrays¹ would be
getting each line in the output: MIDI output to `adeste-choir.midi'...
to be immediately preceded or followed by: New name for MIDI file:Adeste
fideles congo.mid
because the only methods I know for printing an arbitrary line will
print them all in a heap at the very end, after the last PostScript
file has been converted and deleted.
#(format (current-error-port) "New name for MIDI file:Adeste fideles
congo.mid\n")
\midi % MIDI-generating command placed before or after as convenient.
is the method I currently use for writing strings. "write-me" is
allegedly another method. "ly:message" might be another, but any
documentation on these things is either opaque or absent. Perhaps
someone else will chip in...
¹or you could pack the filenames in one bash string, delimited with
a forbidden character like / or : between each one.
Cheers,
David.
