The scsh CVS repository at sourceforge.net contains ODBC and LDAP bindings in the modules scsh-ldap and the directory scsh/scsh/odbc. The LDAP bindings are almost complete and about 1200 LOC C-code and 1100 LOC Scheme-code (about 300 LOC automatically generated). The ODBC bindings consist of about 3000 LOC C-code (partially tricky) and about 2000 LOC Scheme-code. Currently, I'm busy cleaning up the ODBC bindings and changing them to use the SRFI 34/35 exception system. Building the c-stub as a shared module that can be dlopen()'ed by scsh and Scheme48 is also on my list. I'm very confident that migrating those bindings to the SRFI-FFI is not much work. Checking whether the GC annotations are (still) correct and a few search/replace-operations should be enough. > I sampled some of the C code in a version of SCSH that I have on hand > (0.5.2 -- sorry, a download for a more recent version was taking _way_ > too long so I'll risk being embarassed that everything has changed > since then). Actually, that changed completely in the 0.6-series, it's almost exactly the FFI Scheme48 is using. That's why migration of the existing bindings for scsh *0.6-series* and Scheme48 is easy. -Eric Footnotes:  <http://cvs.sourceforge.net/viewcvs.py/scsh/scsh-ldap/>  <http://cvs.sourceforge.net/viewcvs.py/scsh/scsh/scsh/odbc/> -- "Excuse me --- Di Du Du Duuuuh Di Dii --- Huh Weeeheeee" (Albert King)
