World: r4wp

shouldn't ./rebol -v open the console on linux directly?

note: this is happening with MaxV's http://www.maxvessi.net/rebsite/Linux/
2.7.8 as well

just saw this:
http://www.rebol.org/aga-display-posts.r?post=r3wp226x4139
trying a reboot

no luck with rebooting...

xfonts-100dpi and xfonts-75dpi installed (yum install xorg-x11-fonts-100dpi.noarch 
and xorg-x11-fonts-75dpi.noarch)

damn. >2 hrs and no luck
any ideas anyone?

read somewhere that Xvfb may need to be used - no luck yet... :(

ok - finally got it to launch the console

two more dependencies loaded:
1. xorg-x11-xvfb.x86_64
2. xorg-x11-xauth.x86_64

then:
$ xvfb-run ./rebol -vs

>>

works!

Sujoy, what distro are you using?

Amazon Linux AMI 2012.09

WOW, I didn't know of the existence of Amazon Linux. 

It has a very particular configuration for cloud and not for graphic, 
so you need Xvfb.

:)

took a while to figure out, but i found your posts on altme

However if you have trouble with more "classic" distro, let me know, 
so I'll correct the installer packages. See also this:

thanks MaxV

With Kaj here I've got my own private school, but I still am curious, 
so taking a look here. Goodmorning.

Kaj - i've been trying to run the ZeroMQ bindings on an Amazon Linux 
AMI (took a while to get Rebol View running!)

I have installed and built zeromq from the source, but the result 
is a 64bit build, so rebol complains:

wrong ELF class: ELFCLASS64

would you happen to have a 32bit libzmq.so i can use?

Sujoy - Kaj is still asleep, I will tell him you asked this question 
as soon as he's awake.

:) thanks Natasja

Welcome Sujoy :)

Sujoy, you're in luck; last week I added most dependency libraries 
for Windows to my Red testing repository:

http://red.esperconsultancy.nl/Red-test

They're in the MSDOS folder. The 0MQ library is a bit old, because 
newer available versions are a bit harder to unpack in Windows, but 
it's sufficient for my bindings

Hi Kaj
Am actually trying on an aws instance (amazon linux 2012.09)
would you have the .so files?

Ah, as Natasja said, not very awake yet here. Sorry

I'm not planning to add Linux binaries, as they're very dependent 
on the Linux distribution

true

It would be best to force a 32 bit compile on your AMI. If that's 
problematic, best install some 32 bit distro and extract them from 
there

got it working just as you said. forced a 32bit compile of zeromq
works - i can now do %ZeroMQ-binding.r2 with no issues
more anon

works flawlessly so far kaj

Nice to know :-)

An unhappy Ubuntu user (seems disoriented, not even knowing how to 
create a new ML thread):


https://groups.google.com/forum/?fromgroups=#!topic/Rebol/iSgc1-dDZLs

I guess somebody can tell him what he needs to download.

Still no luck for him, more dependencies needed, I guess. Or maybe 
he really needs Core, not View?

Hello, all.


 Back in May I was here asking for lots of help in creating a simple 
 CGI script in REBOL. Wanted to say thanks. It was most appreciated, 
 especially considering how rarely you get new people my questions 
 must have seemed so simple to the point of boring the crap out of 
 all of you hardcore experts. My regular job has insane hours and 
 months pass by in what seems like minutes. The person I was doing 
 it for suddenly had other things come up on his website and business 
 that required attention first so it fell by the wayside. I intend 
 to pick it up where I left off this week during an evening when I 
 have more time. While I had a few minutes I had to send my thanks.


 And I see REBOL might become open source... good to see it  moving 
 forward instead of stagnating.

Welcome back, JohnM!

Thanks for the welcome back message.
 

 I left off asking about the mySQL driver. So I want to insert into 
 a database a random number the code already generated and associate 
 it with an email address that was provided by a CGI form. Have yet 
 to create this in the real world but for now let us assume I will 
 call the database "customers". The people who process the credit 
 card and collect the email address advised me that the address will 
 be labelled "trnEmailAddress".


 After finding the mySQL driver Here is what I figured out using placeholders 
 for things like password, etc. Would appreicate knowing if this is 
 correct.

; Loads MySQL driver
do %mysql-driver/mysql-protocol.r
; Opens connection to MySQL server
db: open mysql://[[user][:pass]@]host[:port]/database


; Send query to database server. Enters random number from above. 
customers is probably the name of the database I will create

insert db ["INSERT INTO customers VALUES (?,?)" "trnEmailAddress" 
"token"]



 Next I need to insert an existing PDF file (an e-book) into a directory 
 created by the script. The directory will be named after a random 
 number that was earlier generated by the script. I am astounded that 
 I can not find the command to copy a file. So the variable assigned 
 to this random number is called "token".

 So I have the following.

make-dir %token/


 How do I copy a file into this new directory? Also, is that the corecct 
 way to make a directory?

Use READ and WRITE together

guys ,i explained my mini project in database and game room ...they 
suggest me this room ! plz help me . my project is about one crossword 
which should show on web page !  i created html form and cgi file 
... when user enter value and press submitt it should save in database 
! my problem is i can not save value from form into database(MYSQL)... 
i am using mysql driver...i can make connectivity and retrieve data 
but i ca not save values ! plz guide me ,i do not have experience 
in REBOL... :(

Please read the CGI documentation suggested to you multiple times.

Basically, you create an HTML file and put it on your webserver. 
Let's call it "form.html":


<form action="form.cgi"><input type="text" name="word"><input type="submit"></form>


Then you create a REBOL CGI matching the "action" used above, so 
"form.cgi", and also put it on your webserver:

#!/usr/local/bin/rebol278 -cs
REBOL []
cgi-values: construct decode-cgi system/options/cgi/query-string


;; Now you can access the "word" value submitted via the HTML form
;; as cgi-values/word.

;; Let's echo the value back to the user, as an example:
print rejoin [
  "Content-type: text/html" crlf
  crlf
  cgi-values/word
]

Instead of echoing the value back to the user, you can do whatever 
you want in the CGI. Such as inserting the value in a database.

Where to use throw-on-error function? How differ from DOing a block?

In R2, THROW-ON-ERROR is used for error handling in functions.

In particular, for error handling in functions with the [catch] attribute.

usually as follows:

my-function: func [[catch] x] [throw-on-error [1 / x]]

(notice the [catch] function attribute)

Got it. Thanks a lot.

@Andreas: i could insert data in database ... now i am comparing 
values which user insreted with correct answers ,i got the result 
of that as well but i want show the result to user on web page ,plz 
tell me what should i do?

print ["this is the result:" result]

result is like:[
    ["c" none]
]
[
    ["a" none]
]
[
    ["t" none]
]
[
    ["a" none]
]
[
    ["e" "e"]
]
[
    ["r" none]
]
[
    ["o" "o"]
]
[
    ["a" "a"]
]

i do not want result like this
