World: r3wp

hi i would like to give you a example i am trying to do of a CRUD 
application

here it is http://users.skynet.be/fc078613/client/client.rip

you mus just de-rip the file with rebol

do client.rip

that create a folder and you must  execute the script with rebol 
START.R

i use rebGui 118 and rebDB203 to do it

i would like to improve my how to !-)

give me some advice

first thing ... add tool-tips for the english translation!

Looks interesting, but I don't speak french :)
And what is it suppossed to do ?

Create Retrieve Update and Destroy records = CRUD

delete ...

it is just a simple example of a create refresh update delete of 
a pretty db rebdb with rebgui

i would like to optimize this with rebdb and rebgui

like we can have example with java

with entity and "percistence"  i would like to have a java EE5  but 
in rebol or better in R3

I would like to see proposals from the community to improve this 
point in R2 and rebdb, rebgui at first.
and later in R3!

Hi. Is there a build-in function do do something like this : given 
the number 5 and the string "abc"  construct the string "abcabcabcabcabc" 
(equal 5 times "abc")?

I think the closest is to-string reduce array/initial 5 "abc"

to-string reduce
 is faster than rejoin

Henrik: thanks you!

I see that reduce is not even necessary.

And if you're really concerned about speed, this is a little faster:

to string! array/initial 5 "abc"

Ok, but I found it strange that there's no build-in function to do 
that.

Well, array just give a block. Maybe you didn't want a string but 
an issue:
>> to issue! array/initial 5 "abc"
== #abcabcabcabcabc

or something else. Strings are just one form of series.

So we use to-<some datatype> to get, what we want.

This looks funny:
>> to email! array/initial 5 "abc"
== [abc-:-abc-:-abc-:-abc-:-abc]

oh : really cool !

Geomol: have you finished your work on LaTeX backend ?

Almost. Some other work came in the way. I believe, I'll get something 
released this week.

Have you got a look at the XeLaTeX output ?

Yes, and it looks nice. I have someting to think about. On one side 
keep it as simple as possible, on the other side, it should look 
nice.

Ok; like REBOL

A motto I like very much and think about daily:
Everything should be made as simple as possible, but not simpler.
- A. Einstein

And my own:
It's more important to get it right than to get it fast.
:-)

For sure !

even when the customers are pounding you for fixes... :-)

Kib2, try this:
>> head insert/dup copy "" "abc" 5
== "abcabcabcabcabc"

And then just wrap it up:

    string-of: func [
        "Returns a string of <value> repeated <count> times."
        count [integer!]
        value [word! char! any-string!]
    ][
        head insert/dup copy "" value count
    ]

BrianH and Gregg : thanks, I need to write all these tips on a page 
now.

as I've just finished implementing nested list in my markup engine.

Still having fun with REBOL, kib? Watch it! You're caught in the 
web now. ;-)

Geomol: more than ever. But I'm rather fed up now working on this 
markup engine. I need fresh air.

I was thinking of a game, and in fact I've found one, but I think 
I need your help. Beware : that's not easy !

:-) We have a game group. You could start posting there and see, 
what will happen.

games

Thanks Geomol. I think I have to study game programming before!

How could I generate a random number (a real number) between 2 given 
values, ie between -pi and pi ?

random pi gives me an integer

interesting
