ok, I've got a simple solution which avoids all
bash/sh/make/stepmake confusion altogether: write a simple
(5-line?) python script. The script is basically just
import sys
cmd = sys.argv[1]
target = sys.argv[2]
status = os.system(cmd+" "+target)
if not status:
print "Something went wrong! Look in",
print target.replace(".ly", ".log")
sys.exit(1)
sys.exit(0) # success
(not tested)
Now, that's a totally gratuitious use of python... but OTOH, why
not? We already require python, and we use it for tons of other
stuff... and really, a
compile-lilypond-book-file-with-warning-about-log.py
script would be *far* easier for casual hackers to read+understand
than all that make and sh garbage. (ok, the script name is a bit
long, but that's easily thought about)
ok, there we go. We have a backup plan. I'm not wedded to the
"small python script" idea, but if all else fails, it will
definitely work. There might be a better solution out there; I'm
happy to hear alternatives.
Cheers,
