Quick CGI question: doing nothing?

[David Bovill]

How do I create a CGI that does nothing - from searching around I came
across the 204 HTTP Response code. So my basic question is how do I write
cgi's to return different HTTP response codes?

David,

a nice read is "HTTP Made Easy" 

for a 204 response, just begin your response with

HTTP/1.0 204 my descriptive text

then put your headers, then your actual data...

Thanks Andre, I have tried a bunch of variations and think I must be making
a basic error as I am getting nothing but "Internal server errors". What's
wrong with this script:

on startup
  put "Do nothing" into buffer
  -- put "HTTP/1.1 204" && buffer & crlf & crlf

  put "HTTP/1.0 204 my descriptive text"
  put "Content-Type: text/html" & CR
  put "Content-Length: "& length(buffer) & crlf & crlf
  -- write buffer to stdout

  quit
end startup

Looking again at your original question, you shouldn't use the 204  
response if you are returning any data. In other words, don't write  
anything after the headers:


put "Status: 204 my descriptive text" & cr
put "Content-Type: text/html" & cr & cr

You can achieve basically the same thing with a standard 200 response  
and a Content-length header of zero.


Cheers
Dave

Re: Quick CGI question: doing nothing?

[David Bovill]

OK - thanks guys that fixed it:

on startup
  put "Hello world!" into buffer

  -- put "HTTP/1.0 204 my descriptive text" & crlf
  put "Status: 204 my descriptive text" & CR
  put "Content-Type: text/html" & CR
  put "Content-Length: "& length(buffer) & crlf & crlf
  put buffer
  quit
end startup

I guess the "Status:" part of the header applies to other status responses?

NB - is there a rhyme and a reason to when to use CR and when CRLF - it
seems pretty well interchangeable on a Linux server, are there any "buts"?
Sam goes with using "write buffer to stdout" or just "put buffer" - any
actual differences?

dictionary question

[Mark Swindell]

Just looking into this, but I'm wondering about architecting a small  
stack that would allow me to input a list of words into a field, and  
then click a button which would return the entire list of words with  
their dictionary definitions.  Ideally these would be drawn from a  
source such as Merriam-Websters student dictionary (online http:// 
wordcentral.com/ ), or another student dictionary on the HD


How difficult would this be to do in Rev, and what might be an   
efficient way to pull it off?  Or does such a tool already exist  
somewhere?


TIA,
Mark

Re: dictionary question

[Phil Davis]

Hi Mark,

I've never built a lookup tool like this but it reminds me of one I used for 
several years. It used the DICT protocol. If you've never looked at this 
protocol, you might find it interesting. Typing 'DICT protocol' into google or 
wikipedia will bring up a veritable firehose of info about it!

The http spec calls for crlf, but it seems Apache is very nice and  
changes from cr to crlf when sending the response to the client.  I  
don't think all servers do this.


If in doubt, I'd suggest using crlf.

Actually, I think it is Rev that does this, just as it changes line 
endings in imported text files and across platforms in stacks.


I've never used anything but cr, and it always works.

>Hi Bob, Charles,

Rather than putting an RTF file into a field, I would put it into a custom 
property. That way you don't have any risk of it being changed to conform to any 
requirements the field might place on it to make it displayable (even though the 
field is hidden).


If it's stored in a custom prop, your app can then write it to disk when needed.

Some years ago I did this with an application needed by my Metacard app. My app 
retrieved the other app from a custom property, wrote it to disk, used it, then 
deleted it when done. Worked great. That was on Unix but it shouldn't make any 
diff what platform. (Famous last words!)



I do this all the time with Rebol and HTML scripts without trouble. They are 
only texts, after all, just like RTFs.

Your app can also write it to disk from the field.

But as you say, "Famous last words!"
It might be different when you are doing this with an app.

Hello,

I have a lot of word-files (with Footnotes), which I want to print to  
pdf on Mac OS X using the button in OSX-Print-Dialog.


Can you tell  me how to do? How to do it in Applescript?

BTW: I learned with your help to use the shell command to convert doc  
to pdf, but that doesn´t work for doc-Files with Footnotes.

Basically you get a URL that includes the word in the search string.
Do a few site searches and copy the url that is in the browser, then build
the same string in a repeat loop for each word.

Pretty simple once you get the hang of it.

Re: Methodology forprogramming challenge

[Terry Judd]

Why not as Ken suggest use imageSource (htmlText/whatever) but use a fixed
line height in combination with identically sized images which either
represent all or part of an icon depending on the size/height of that icon.
So if you have a tall icon - say three units high - you use three lines each
with a different imageSource character.

Re: Methodology forprogramming challenge

[J. Landman Gay]

Just a thank-you to everyone who helped me brainstorm on the dance 
notation idea. While all the various pieces of advice seem do-able 
individually, the totality of it all makes me uncomfortable. There is 
hardly anything that wouldn't be a hack -- printing, screen display, 
data entry, all of it. I've had plenty of times where I had to use a 
work-around here and there, and in general those do fine, but when the 
core guts of the software needs to be a kludge I'm not comfortable. 
There's just too much that could go wrong, and it is too susceptible to 
multiple problems. After some consideration, I don't think I'll take the 
job.


Rev is good for just about everything, but this one project seems like a 
rare exception to the rule. If anyone feels differently, I'd be happy to 
pass the project on to you.

non-blocking post

[Dave Beck]

 

Is there any way to make a non-blocking post request? Often times when
posting multi-part form data to a URL the post operation appears to time out
and an empty result  and the "it" variable are both left empty if there is a
lag before the server responds. The problem seems to also be related to the
amount of data being posted, but it seems to be most dependant on the lag
time with the server. Is there a non-blocking way to post data to a URL that
may not be subject to this (apparent) timeout issue? Thanks very much in
advance for any help or advice.

 

(I did try setting the socketTimeoutInterval to a very high value but the
problem persists.)

 

Thanks,

Dave

Is there a currentCard Property?

[Len Morgan]

I've got an application that has a stack with several cards that are 
selected by a selection from a combobox (which is in a toolbar group on 
all cards).  I need to update the information on the currently visible 
card when a new card is selected from the combobox or when the current 
record is changed (in another group on all cards).  Since this stack may 
end up being 50+ cards with a lot of data (from a database BTW), I don't 
want to update every card every time new data is selected.


Is there a currentCard property or function I can use?  I'm going to 
have an updateFields handler on each card that will update only the data 
on that card.


Any ideas?

Thanks!

[Phil Davis]

Also, 'current card' is a synonym for 'this card'.

It's listed as unsupported in the Engine Change Log file, but you can use:
   put the currentCard of stack "Whatever"

Another possibility is to get "line 1 of the recentCards".

Both of these allow for the stack with the cards to be other than the
front most stack at the time.

Cheers,
Sarah

How to tell if a stack has been edited

[Sarah Reichelt]

Is there any way to tell if the data in a stack has been edited? I
don't want to have to keep track of every field and record any changes
so I am hoping there is a hidden property somewhere that can tell me
this. It has to work in a standalone, not just in the IDE.

TIA,
Sarah

Hi Len,

It may be that you could trap the opencard message further back in your stack 
script and always update the field values based on the card name like this...

on opencard
put the short name of this card into fld "title"
put the myCustomAttribute of this card into fld "someOtherInfo"
pass opencard
end opencard

If you have cards that don't have the fields to be updated inthe stack just put 
an if statement around the put statement/s like this...

on opencard
 if there is a fld "title"
 then
 put the short name of this card into fld "title"
 put the myCustomAttribute of this card into fld "someOtherInfo"
 end if
pass opencard
end opencard

Regards

John

Re: How to tell if a stack has been edited

[Phil Davis]

Hi Sarah,

How is the data stored? In fields, custom props, ???

I'm thinking you might have to detect changes from messages fired (e.g. 
closeField) but I would love to be wrong.


I suppose you could get the md5digest of the stackfile at preopenstack time and 
store it in a global; then at closeStackRequest time you could do it again 
and... naaah, that assumes the stack was saved along the way.


Is there some kind of equivalent way to see if in-memory stuff has changed? I 
guess that's your basic question, isn't it?


Hmmm. This is less easy than one might wish. :o)  Please do tell us if you find 
a way.

Note the wildcard, which wordnet doesn't support.  Of course, wordnet is
vastly richer.

Newbie Question

[Simon HARPER]

Hi there,
I'm trying to delete the selected rows in a list field - however to  
make this work I have to do it in reverse so deleting


2,3 out of say 1-5 doesn't work is line 3 is removed incorrectly -  
therefore I need to remove 3, 2


I'm trying this (when the 'delete' button is pressed) code fragment  
as part of the delete button, however,

  sort items of tLineList descending of each

doesn't seem to do anything, I wonder if you cold help me with what  
I'm getting wrong here - also is there a 'in reverse' option for the  
repeat loop?


on mouseUp
  put the hilitedlines of field "listCats" into tLineList
  split tLineList by comma
  sort items of tLineList descending of each
  repeat for each element tLineNumber in tLineList
delete line tLineNumber of field "listCats"
  end repeat
  sort field "listCats" ascending
end mouseUp



Cheers
Si.
