World: r3wp

Thanks for updating INCLUDE Ladislav! I use it a lot, and this will 
give me more reason to try some things under R3.

I'll just copy my email here, as I don't know everybody's on the 
ML:


This is great! First real R3 extension. Just few suggestions overall:


- we should not really forget about using schemes/ports - aproach 
you used is really an old-school, non rebolish. Surely useable, but 
maybe I am just too much used to nice other-rebol-db-driver interfaces. 
As for ports and blocking argument - wasn't R2 ODBC eventually blocking 
too?


- embedded extension is nice, but as well as for SQLite Robert did, 
I suggest to use DLL aproach, with tiny wrapper - you save novices 
from the need to set-up the compiler.


Other than that, I am very surprised that somene actually finally 
produced something VERY usefull, along with nice docs. Just - wow, 
and thanks :-)

Thanks, Petr, you're feedback is appreciated! Just some comments: 
Yes, I was thinking *ports*, too, but with R3, the not yet available 
*devices* will be an even better way to go. The API with open-* and 
close-* isn't really nice but it's not yet set in stone, no way. 
Definitely I'll compile to a DLL, too, that's just a matter of time.

Christian... compiling to a db, requires two lines of text to change 
in you C code, and a change in compiler so that it compiles as a 
dll instead of an exe.   really. it takes 15 minutes to change (I 
did so as a test with one extension I was using to try out the new 
interface)

on top of it, you won't have to play around with updating your host 
itself each time a new release is done.   The host itself which is 
subject to change very often right now.

These two lines, Max, should be somet #define REB_EXT and a RXI_LIB 
RL  declaration, but that doesn't get me too far. This "15 minute 
 change" is going to cost me hours ;-) And the funny thing is that 
I had it working as a DLL first with A102/A103 and then changed to 
embedded extension. Now I don't find my way back ...

looking at it now... there are a few changes... but look at this 
code by Andreas, and it should get you up and running within minutes... 
basically copy/paste all the appropriate stuff and change what is 
specific to your code.

That's what I was doing, the comiler still is complaining about missing 
stuff. Will have a look into this tomorrow.

note that you cannot use the hostkit API directly, only the extension 
API.


what I did was a separate host-kit like header which creates defines 
for the functions I needed.  I added a platform #ifdef, so that it 
will automatically adapt to new platforms if I try to port it.

ChristianE: I took the liberty of adapting your code to also allow 
building it as DLL. Here's the complete diff:

https://gist.github.com/fa147ed65ee752b23133

Building as hostkit-embedded extension is the default, the ODBC_DLL 
define triggers building as external extension.

This also adds a target to the makefile, that allows buidling the 
external dll via `make ../lib/ext-odbc.dll`.

Andreas, this is great! I'll apply the changes tomorrow evening since 
I'm not a my dev pc now, and put the DLL on the page for others to 
download and play it..

(play with it)

Andreas, thanks again for the diff ! I wouldn't have come up with 
the solution. I've just put the DLL online.

Perhaps you could write a small tutorial on how to create extension 
and dll while it's fresh in your mind :)

NIce idea, Graham.

Please do!

Max is Renote like National Velocity?

yeah, it seems to be very similar (You meant notational Velocity 
I guess ;-)

though the title is actually called tags, they are the same concept... 
only in renote, they are pushed on the right, to be less obstructive.

funny I never heard about NV, thought the idea is borne of the same 
thing... though renote already seems more powerfull with 3 days of 
dev behind it.

(because of macros)

note that I've tested with hundreds of notes and its still very fast., 
even the scrolling.

auto-tagging is also flexible, especially when you use the parent 
modes.  this automatically adds tags to your note based on the parent 
it is in.
this is done even when its grouped later.  


I will be adding a "get all children" command so that it can be used 
in macros. (add/remove tags to a whole group)

I also plan on adding other export modes, one being for make-doc 
 it would allow us to edit data and look at it via make-doc strings 
in a single click.

Z:\Downloads\Applications\r3-cgr\cgr-apps\r3.exe


This application has failed to start because the application configuration 
is incorrect. Reinstalling the application may fix this problem.

Not sure what that means...

I've never seen this error !  on what os?

XP under VirtualBox

Sounds like corrupted EXE

Maxim, the exe doesn't work for me either. I'm gettingsomethinglike 
"There was an error during execution" or so in a Windows message 
box. Win XP here.

what size was your zip.

it might have corrrupted on upload... ' :-/

5.660.639 bytes

darn, I just downloaded and unpacked it... works for me...  :-(

hum... ok. its correct... let me try something else.

are you able to start the r2.exe in the bin folder?

On Win7 when starting r3.exe I get "The application has failed to 
start because its side-by-side configuration is incorrect."

Maybe http://buffered.io/2008/05/17/resolving-side-by-side-configuration-issues/
has some hints ...

ahhh... compiled using debug mode.!

ok.... this is going to take a few minutes... since I have to update 
the release mode so it has the same setup as the debug mode.

I got it to work...pretty cool. Maxim!

What's with r2 stuff...does this work under R2 too? I thought this 
was R3 stuff only?

Is this just nice excercise to show the possibilities, or is there 
any feedback from Carl, if he is willing to extend API to support 
such stuff?

no its just that I'm using r2 to build files.

pekr, its not just an exercise.


and yes Carl is interested, it just wasn't obvious what would make 
it easier to hook into, now we have something to look at and discuss.

I am unable to get the external dll working when doing a Release 
level build.  it compiles without any errors... 


but when running the same script which is working in debug mode, 
I get this  error in the console:


** access error: cannot open: %opengl-cgr.dll reason: "not found 
or not valid"

very strange

Perhaps because of the option -s "which strip the symbols from binary"

Some things that might cause it:
- memory alignment
- uninitialized globals that are used
- missing entry points (use something like dump to see it)

might be the struct alignment.... I just found that it wasn't set 
in release level

yep... that was it  :-)
