Re: Posting to LiveCode Server

[David Bovill via use-livecode]

Todd, the browser auto-translates things you type / copy paste in the url
bar to something it expects you want as a url.

You have characters in the url that need to be escaped (<>)

Re: [Ann] xaLib - library to extract data from an array.

[Bob Sneidar via use-livecode]

Heh heh. I wasn't asking you to actually USE convert to sqlite memory in your 
library. I was just saying that for a few xqueries yours a really useful 
library, but for lots of queries against a large array, the performance of 
first converting to an sqlite memory database and then querying that and 
converting back to array would likely be noticibly better performance wise. 

I already wrote code and posted it for converting a numbered array to a sqlite 
memory database so let me know if you didn't get that so you don't have to 
rewrite it all.

Re: [Ann] xaLib - library to extract data from an array.

[Alex Tweedly via use-livecode]

Well, it's only a case of "I expect ..." so we shouldn't trust my 
intuition until we've benchmarked it a bit :-)


Having said that - we will still be using script to iterate over the 
keys/elements of the array, so there is likely to be some cost there - 
even before we allow sqlite to index some columns.


I've just started looking at it from the performance point of view, and 
reduced the time for the simple case in the included test stack by 95% 
so it doesn't feel so bad now  but I'll need to completely rewrite 
the main functions/handlers :-(


I'll try to import the data into an sqlite DB and compare against that 
too - will report with some numbers tomorrow (and come up with a more 
reasonable test case.

Both use hashed lookups to find data.  What would be needed to bring

Re: How to get the line break char?

[Jerry Jensen via use-livecode]

Tiemo,
Is the task to compare two CSV files regardless of their line endings? If you 
don’t care what the line endings are, as Brian points out, using “file:” to 
read them will convert all line endings to just LF. Then there is no problem 
comparing, right?

Re: [Ann] xaLib - library to extract data from an array.

[Bob Sneidar via use-livecode]

I was thinking about that. Depends on what you mean by par. If you are not 
indexing array values, then you will have to touch every array element each 
time you query. It's back to one pass sql conversion then, and you would get 
all the benefits of sql in the bargain. The only time an array query api comes 
in handy is if you are only trying to filter an array for a key:value a few 
times. If you have to do this many times, conversion to a memory based sqlite 
database could really pay dividends for a large array, especially if you took 
the time to index the columns that mattered most. 

I'm going to put together a benchmark soon I think. Shouldn't take too much 
time to do so. I have some good SQL data I can punch into an array then create 
a memory based SQL database from.

We figured it out. When you do a Post to LiveCode Server, you MUST call $_POST
or $_POST_RAW. If you do NOT then the server script will NOT process and
returns an error. We just put the file up there is see if we could get a
return. But when posting...you MUST make one of the two calls.

Thanks also to Elanor for the help,

Todd

Re: Posting to LiveCode Server

[Tom Glod via use-livecode]

I was going to use LC Server until I realized there was a built in httpd
server library present in LC 9 I ditched LC server mainly because
it smokes LC server in performance.  Just bringing to awareness all your
options.

http library is so simple to use with callbacks for each request.  its so
awesome.  good luck.

LC PDF Viewer

[Knapp Martin via use-livecode]

I'm just getting my feet wet with the PDF viewer. Anybody worked with that and 
can help give me with a jump start? I find the dictionary not very helpful. I 
learn a lot better from actual working examples. I didn't see anything in the 
online examples.

Basically I want to be able to select a PDF and then extract the text from it 
page by page.

Thanks,
Marty

Re: [Ann] xaLib - library to extract data from an array.

[Alex Tweedly via use-livecode]

No, no SQL database involved.

The array is kept untouched - although you can use the xaCopy function 
to make a copy of some subset of the data, in general it's going to be 
more efficient (both space and time) to keep the array.


There is no relational anything - it's just intended for wen you are 
using a LC array as a key <--> value data store.


You can do sorting by multiple columns, using xaOrderBy (each column is 
sorted in (reverse) turn, depending on the fact that LC's sort is 
stable).  (note it does the key matching as one phase, then sorts those 
keys as a second phase).


I expect the searches etc. would be faster with SQL / memory database - 
but if you are using the array anyway, this way can be simpler, easier 
and it avoids any sync issues if the array is being changed - as well as 
allowing you to keep only a single copy in memory.

The advantage to converting to a memory based sqLite database is that there are 
features unique to SQL, like relational queries and sorting by multiple columns 
that you cannot get by simply extracting matching keys. The downside *might* be 
the time it takes to convert, but it's one pass through the array (or arrays), 
which I assume you are having to do anyway.

I use a memory database, but of course you wouldn't have to. Any SQL database

[Ann] xaLib - library to extract data from an array.

[Alex Tweedly via use-livecode]

Bob Sneidar and Richard Gaskin said :

  > do the same thing by iterating through all the elements of an array,
  > but what if I wanted to do multiple queries? It's easier for me to

I hear ya'.  I find myself tempted way more than I have time for to
write an xquery-like library for working with arrays.  We could sure use
one.

So, I was tempted too :-)

But I decide there was no need for the complexity of xquery, and it was 
better to keep it simple, along the lines of Andre's DBLib, or 
revIgniter's Database lIbrary.


Hence : xaLib  - eXtract from an Array Library
   which can be found (I hope) at github.com/alextweedly/xalib

(I may not have done everything right on github - please let me know if 
I need to fix anything).


There a script-only library, and a very simple test/demo stack as well 
as some basic documentation.


Summary:
the data is held in a LC array. You
 - (optionally) specify the matching criteria (by a series of calls to 
xaWhere)
 - (optionally) specify the ordering needed (by a series of calls to 
xaOrderBy)

 - (optionally) name that query for later re-use (xaNameQuery)
 - then run the query by calling xaQuery, which returns the set of keys 
matching your needs.
 - (optionally) make a copy of the 'interesting' data (but usually 
better not to do this).


Any suggestions / comments / contributions welcomed.

One other consideration is how you are opening the file. Using “file” will
end up converting to just LF. You will need to use “binfile” to examine the
line endings native in the file.

Re: Posting to LiveCode Server

[Mike Bonner via use-livecode]

Can you share the code to the page you're actually posting to?  Its
sounding like its not actually returning any output, causing a 500 internal
error.  Just to let you test, I set up a quick and dirty page at
http://guidezone.info/test.lc
The code in the page is as follows.

"
   end repeat
else
   put "Error: No data posted" -- gotta put somethingto avoid a 500 error
end if
?>

To test it, I used the following in a button.
put "Accept: text/plain" & CR after tHeaders
put "Content-Type: application/x-www-form-urlencoded" & CR after tHeaders
set the httpHeaders to tHeaders

put liburlformdata("name","Chi","gender","male","color","black") into
tPostData

put tPostData & cr --so that I can see the generated post string

post tPostData to "http://guidezone.info/test.lc;

put it && the result after msg


This works for me, though as I said, I don't have tsnet.  You're welcome to
do test runs against my url if you like. If it works for me as written, and
not for you, i'd be pointing my finger at tsnet.

Tiemo.

I guess I do not understand.

put charToNum(the number of chars of line (lineOfInterest + 1) of yourText)
into tChar

Then tChar can be compared to the "tChar" of any other line.

Hi.

You cannot ask for the "last" char of a line, because LC will give you the
last "non-control" char.

Say you have the below text in a field:

abc
def


So the last char of line 1 is "c". But the number of chars of that text
snippet is 7

But numToChar(char 4 of fld 1) = 10. That is a return char between the "c"
and the "d"

Yes, thats what I said. I am looking for an alternative to examine the line
break if it is LF, CR, LFCR or whatever

Re: Posting to LiveCode Server

[Matthias Rebbe via use-livecode]

Todd,

is there a reason why you are not using the function libURLMultipartFormData to 
format the data before posting?

We are using the post method for different tasks including uploading really big 
files to a livecode server, but we always use libURLMultipartFormData to create 
the form data.

Btw.which version of LC server is running on your side?

Posting to LiveCode Server

[Todd Fabacher via use-livecode]

Any Help will be appreciated...

Normally we use Node.js, but we are trying to get LiveCode server working.
We are doing a simple test:




If I put the URL in a browser I get back, "It works"

https://api01.triviamatic.tv/round_create.lc



*put* "Accept: text/plain" & CR after tHeaders
*put* "Content-Type: application/x-www-form-urlencoded" & CR after tHeaders
*set* the httpHeaders to tHeaders
*put*"fullname=chi=male=black" into tArgList
*post* tArgList to URL "https://api01.triviamatic.tv/round_create.lc

"
*put* the result into tError
*put* it into tFormResults


The tError is:  tsneterr: (52) Empty reply from server

and tFormResults is null


I need some help ASAP. This is SUPER frustrating!!

How to get the line break char?

[Tiemo Hollmann TB via use-livecode]

Hello,

I want to compare two CSV files and I suspect that there is a difference in
the kind of line break. With charToNum(last char of line 1 of field "foo") I
can compare the last visible char of each line, but how can I get and
analyse the line break char that is used?

Thanks

Tiemo

Re: DataGrid Column Labels

[Terence Heaford via use-livecode]

I’ve had a look at various behaviours but rather then make a mess of everything 
can you give a blow by blow of your actions please.


Thanks
