I'm glad it to hear that.
In addition to the concerns you raised, I realized that sparsetools.h
was a bit too large itself.
At some point I will want to reintroduce the unrolled variants of
bsr_matvec and bsr_matmat. If these template-heavy functions cause
similar problems for you, let me know and we'll figure something out.
Ideally we would generate the SWIG interface files and wrappers
dynamically. We could then automatically create interface files on a
per function basis (if need be) without polluting the repository.
E.g. csr_foo() -> csr_foo.i -> csr_foo_wrap.cxx
In this case csr_foo.i consists of only a few lines, much like csr.i
or dia.i do now.
I wouldn't recommend this approach yet, since few people have SWIG
installed and even fewer have the most recent SWIG installed (which is
necessary on some platforms). Perhaps in a year or so.
