Possible Feature Request?

[Fr. Samuel Springuel]

Right now we have ly:source-files which contains a list of all input files 
which have been opened up to the point of it’s call, but there is, so far as I 
can tell, no equivalent for output files.  How difficult would it be to add 
such a scheme function/list?

As I see it, LilyPond obviously knows the name of each file it writes to at the 
time of the write operation (regardless of the kind of file it’s writing), so 
it ought to be possible to simply have it store said name in a list (perhaps 
with a check to make sure it’s unique if LilyPond writes to the same file 
multiple times) either just before or just after the write operation.  
Temporary/intermediate files would not need to be added to the list (if 
LilyPond knows they are temporary/intermediate at the time of the write) or 
could be removed from the list as part of the clean-up operations that remove 
the files themselves.

Of course I’m entirely speculating without having examined the source to look 
for the various write operations.  Could one of the developers with more 
knowledge of the source be so kind as to reality-check this idea?
