MySQL driver (native)
[1/3] from: m::koopmans2::chello::nl at: 18-Apr-2001 13:22
Hi all, I have used Command 1.0 to develop a mapping to the mysql library, something that you can use very easily from Command or a Pro versions. The main reasons to do it this way instead of the native Rebol way: - Speed of the native libs (depends on the network as well) - Protocols change, I don't want to that myself. - The API has already built-int support for some handy stuff: ping, database error handling etc. I will add more to the interface. So that's why when Doc Kimbel already has a rebol native driver. And it is good to be able to do it two ways :) Some things will be definitely be faster using the c libs, while being able to run it on any Rebol platform (Doc's solution) is an option as well. You can download the script at www.erebol.com (or .org or .net) for free (MIT license, which is even less restrictive than BSD, which is less restrictive than the GPL). This should motivate people to buy pro :) [Really, you should. It adds great value and you support this brilliant work for a low price] There is one limitiation: due to the nature of the free command (free doesn't free memory that is allocated outside of Rebol) memory may get exhausted if you do a lot of queries. This will be fixed in Command 2.0, I have been told. There is some other stuff on erebol as well: - erebol: "embedded rebol" , a preprocessor for Rebol Server Pages. Who needs PHP, JSP or ASP (Ralph are you out there?) I have a sample config for Apache to be able to serve .rhtml files. - Design by contract. This defines a contract definition: a: contract [ b c ] [ pre [ [ b > 0] ] post [[ c < 0 ]] [ d ] [ ;d is a local do something useful here ] All of this I / we am/are using in some major legue commercial projects (I work at a very large bank-insurance company in Europe), so that's why you can consider it reasonably tested. I have erebol hosted as a service to the Rebol community (yes, I pay for this, but it seemed a good idea to do something back). If you have good scripts that you want to publish there (under the MIT license, see www.opensource.org) you can mail them and I'll put it there. Thanks, Maarten Koopmans

just a note - from the technical POV I hope Rebol/View/Pro library interface is going to be exactly the same as in /Command? I hope so :-) -pekr-

It is / will be the same, but free doesn't work as you'd hope right now (in all versions). Anyway, free for the taking so enjoy. -Maarten
