>I doubt FFI is not included in any typical build of CLISP.
I have to correct myself: I forgot some of the compilation problems =
with ffcall mentioned by Will Newton et al.
No ffcall =3D> no FFI, thus there are builds of CLISP on UNIX without =
However, Dan's gdi module should still work, since I've recently =
pointed out that modules do not necessarily depend upon the FFI.
An interesting(?) call for volunteer task could be:
better integration of regexp into CLISP
a) it depends on the FFI
b) as such, it uses "1:1" C-style strings, whereas CLISP uses some UCS =
internally. The result for each call is character encoding conversion =
from CLISP's internal format to custom:*foreign-encoding* (probably =
c) because of 1:1, it doesn't work with all supported encodings, e.g. =
not with Chineese, Korean or Japaneese ones
d) the API is not efficient at all (w.r.t. to multiple invocations), as =
I pointed out in April, subject "About speed, and regexp&FFI in =
The better regexp module could operate directly on CLISP strings, =
without encoding conversion and copying strings on the stack.
i) A version of the regexp code which operates on two-byte characters =
would integrate much better with CLISP.
ii) While doing so, the regexp interface could be turned into a "pure =
module", not needing the FFI (for howto see my module cookbook).
1) I don't know whether the GNU/perl/xyz regexp code would have to be =
changed for this to work.
2) Furthermore, CLISP also uses some 7bit strings internally (e.g. on =
some constant symbols names): don't assume everything is UCS-2.
Of course, one could argue this is solely an optimization area (except =
for the 1:1 restriction). Time and effort might be better devoted to =
bringing new things to CLISP.
Difficulty: unassessed because of 1)
Interest/Fun factor: not assessed
