AltME: R3 Extensions


Good initiative, Tomas. For CGI, I think you should get by purely with mezzanine code (environment, stdin, stdout).
Good initiative Sunanda
(And I think technically, no native code would make CGI not really an extension, but a "delayed embedded module".)
"...we wouldn't need of 2 standard versions of Rebol (core and view)..."
That would be great, I remember that it was very confusing to me to have Core, Base, View, Face, Command etc.
Giuseppe -- thanks, but it was TomBon's idea in the SELF group.
Andreas, yes exactly these considerations are important because the sore temptation could lead into an overload and therefore polluted R3 with embedded extensions beyond a usefull 'R3 with batteries included' ;-)
there are tons of usefull libs and free code out there, compression, crypto, text processing, serialisation, image manipulation, audio, math, ai and very important;  db connectors. filling these areas step by step is a lot of work but I think it's worth. As soon R3 has reached a stable structure (couple of weeks I think) a new bounty system should be established for extensions we need but haven't the time or skills to create those. Just now I started with a simple one to get a feeling for the handling and any advise in this is highly appreciated.
Which library do you suggest for universal DB connection ?
Guiseppe, I'm going to add my ODBC extension, which is already available as dll. It's Windows only for now, but with the sources available, incorporation of Linux and Mac ports shouldn't be a problem.
There are several DB layer aggregators like OpenDBX, libDBI or even APR (as a function part). Problem here is most of them are looking outdated.
Afaict some of the ODBC APIs for Unix/Linux are kept up to date. Supporting those too would be a good idea. ODBC isn't Windows-specific.
Some NOSQL connectors would be fine too, not all supporting a straight REST interface. MongoDB, Redis and Tokyo/Kyoto offers a very clean C api.
Tomas, if you're working on Windows, you can write your extension in Red/System, using the dyn-lib-emitter branch of Red:
Kaj, thx for the info. now I am on the serverside (nix) to compare the handling and performance with the current Lua stack I am using.
Would be great if we could work on some extensions later, on the base we did before if you like ;-)
I'm open to it. R3 extensions in Red/System on Unix requires the dyn-lib-emitter branch to be finished and extended to other platforms
Alternatively, a Red(/System) host could be written that loads the R3 library, but that's not so simple, because there's no real separation in the R3 host code between the platform-specific and cross-platform parts of the host. That means you're almost forced to write the host in C, pulling in the existing C code
should Red/System not be advertised/pomoted a bit more as a better way to write rebol extensions, now that Rebol is OS? I mean, it should be listed on the Rebol GitHub project as the best way, if indeed it is. Possible on, if Carl would allow it.
possible = possibly
I think so, but only after the dyn-lib-emitter branch is finished
