Hello, On bigger Projects, the resulting output executable can be very big for small Solutions. As this reason, I have look to an alternative, and found one of them: that I can load external Files, and execute them with Prolog Interpreter or the virtual zip maschine. and I could get the Code fro…

On bigger Projects, the resulting output executable can be very big for small Solutions. There should a topic or post on this site that talks about using tell/1 and told/0. The example would look something like ?- tell('fiilename.pl'),goal(1,2,3),told. such a file can then be loaded with IIRC i…

[image] EricGT: For the real bleeding edge there is the SWI-Prolog interface for RocksDB . If you do any work on this, please coordinate with me. I started extending it but got sidetracked into improving the C++ interface (SWI-cpp.h). I’m also wondering whether RocksDB or redis, or something …

[image] peter.ludemann: it might make sense to have an over-all interface that can work with a variety of database-ish “engines”. Please don’t. I would hate to lose efficiency for the sake of a unified back end. SQL, Redis, RocksDB, RDF and network databases are each so different that it coul…

Thank you for your feedback. Please sorry, the Subject has a little Typo: “…big Projects…small Solutions”. This is Paradox/Type, so the Admins can replace “small Solutions” with empty gap. I am not on the state, to foreign function calls (FFC). I have thinking about the PCE/XPCE to have a own Qt…

I can see rocksdb on msys2, what is the issue with Windows?

For me, msys2 is not new to me. I use the the mingw32, and mingw64 very often with fpc. But the data base RockDB is new to me. And I don’t know, if it has SQL facilities, so I don’t need learn C/C++ Library calls (okay, some background in it are useful. But it is not the actual problem in using S…

Not sure what you are after. You can load code from anything that can be turned into a stream, which is basically any source. You can also unload code. For temporary reasoning there is in_temporary_module/3. As is, there are a few objects that are not subject to GC. These are functors (…

I work under Windows, and can esily create .dll there like under Linux the .so files by simple command line: # gcc/g++ -fPIC -O2 -o libname[.dll | .so] objects.o -L/lib/path -lprolog -lc [-l std++] # strip libname[.dll | .so] The text in brackets are optional. Important gnu c/c++ option for DLL/…
