Re: LC Server & Server Based Stack?
Hi Mike, This seems a little crazy to me. I can have two stacks open in memory in LiveCode, and I can send a message such as “mouseUp” from one stack to a button in the other stack. The button in the other stack outputs some messages to the message box and puts a message in a field on that stack and that all works just fine. I’m able to view both stacks on the screen at the same time. (This is as it should be.) I send the same message from the server to the button and the messages which normally go into the message box end up in the display of my browser which seems a little strange but Ok I can accept that. The other message which was supposed to go into the field never gets to the field which makes it look like the button ignored that statement completely although it executed everything else it was asked to perform. That message doesn’t seem to go anywhere as it doesn’t even end up being displayed in the browser and ends up in the bit bucket in the sky. (Again, I can see the open stack on the screen at the time that I tell my browser to execute the server code.) Shouldn’t a message be a valid message no matter where it comes from? (Hence my crazy feeling about the whole thing.) So you are telling me that I can send a message to closed stack to modify it, that I should save it after the change, and then reopen the stack to view the change - yes? The file communication idea makes things a little more complex but is certainly doable. I’ve never done anything with sockets - are there any good examples out there you can point me to for this?

Re: LC Server & Server Based Stack?
Yeah, thats what I'm saying. Think of it this way. If you make 2 standalones, run both, and have 1 standalone try to put text into a field of the other, it won't work because they are each running their own engine instance. If one engine instance opens several stacks they're able to talk because its all through one instance of the engine, and they're all interconnected through the engine. Lc server is an instance, and the standalone, or ide that has your open stack is an instance. So there is no direct connection between the 2. It would be like opening the same text file twice in 2 separate text editors. If you type in 1, the change doesn't appear in the other. You'd have to type in 1, save the changes then reload the text in the other to see the changes that were made. If using a file to update will work, it should be simple enough.. (and not require stacks on the server side.) Have the server write the necessary info, and have an update button on your stack that will grab the new info, or have the stack keep checking for changes every so often, and update as necessary. As far as sockets, chatrev is a pretty awesome example. If you click "resources" in the main toolbar, then select "sample projects" on the lower left, there is an "internet chat" that you can poke around with to get a handle on things. If you decide to go the socket way and the cgi (non lc server) method, i'll be little help. I'm not even sure which versions of the lc engine will work for this, but you said you already looked at jacques page, so are on the right track. I have mentioned it before, but there is the revhttpd stack.. If you don't need multithreading, it would make a great starting base. (and another way to explore sockets too) I love the thing, especially the ability to add commands to the stack that are then callable using a get request of the form cmd=commandtorun On Sat, Jan 21, 2017 at 8:47 AM, Rick Harrison via use-livecode < use-livecode@lists.runrev.com> wrote: > Hi Mike, > > This seems a little crazy to me. > > I can have two stacks open in memory in LiveCode, and I > can send a message such as “mouseUp” from one stack > to a button in the other stack.

Re: [ ANN ] Release 8.1.3 RC-1
Thanks to the logs shared, I was able to identify the problem with DGH stoping the plugins loading process. The problem is in the DGH_Help substack (the DGH documentation) which the IDE is considering as locked. Don't ask me why, this is the only substack in DGH which has a couple of properties set, such as the cantdelete property. Setting this property to false in the inspector is solving the issue. Will update the bugzilla report with this information in case this new behavior is not something expected.

Boring but important - selling a download product for Windows
Sorry to witter on after I’ve asked this list a lot about code signing etc so often. The excellent help I’ve had has enabled me to sign both the app I want to distribute and its installer - in fact I’ve done this twice, once for the Mac version of this app and once for the Windows version. The intention is to sell the product by offering a download from a web site, using FastSpring for the payments, and incorporating Jacque Gay’s Zygodact to provide unique activation keys. All this works fine, except for the Windows download, where Norton, Chrome and even Windows 7 all attempt to prevent either the download or the execution of the installer. Again with advice from this list, I know where some of the problems lie (though not the one with Windows, which reports the installer as having an ‘unknown publisher’ but later displays the publisher provided during the code signing!). My question is, what do other people do about this? If you generate a new desktop program for Windows and try to sell it as a download, how can you strip away all this nonsense for the average purchaser? So far all I can think of doing is to issue a warning on the web site that explains what do do if Norton ‘quarantines’ the program. Even this does not cover all the obstacles in the poor purchaser’s way. Doesn’t this affect everyone trying to offer a new executable download? [noise of grinding teeth…] TIA for any further views.

This is just about the only hitch in the process, because Windows presents the zip folder as a regular folder and users think they can just double-click the app inside the zip archive. Other than instructing naive Windows users to drag the app folder out of the zip archive, there have been virtually no other issues. The signed app itself works fine without interference from the OS.

Search and replace Raw unicode html-hex-dec characters
I have *.html files that were extracted from epub documents.
At our instruction, the company preparing these epubs was requested to use
Unicode throughout and avoid all ANSI chars (i.e. us the Unicode for mdash and
not — from the mac keyboard)
If I drop these on any browser they are perfectly rendered.
(see on line example here:
http://www.himalayanacademy.com/media/books/living-with-siva/web/part1_06.html)
When I open these as UTF-8 unicode files in BBEdit. I see the characters like
this:
The knowledge of how to realize this oneness and not create
unwanted experiences along the way. The peerless path is
following the way of our spiritual forefathers, discovering the mystical
meaning of the scriptures.
To make life interesting, some files were exported with the decimal form and
other with the hex form (”) some of the files mix the hex style notation
along side the decimal.. in the same paragraph block… browser doesn't seem to
care about that, so we are getting and then later in the same
paragraph: "¶
which is also exactly what you see if you look at source in the browser for the
page.
I need to be able to target, for search and replace, a subset of these
characters. In particular, we have troublesome
1) Pilcrow (Paragraph Sign) ¶ #old "run on" paragraph mark… which we
want to turn into block paragraph form: just have an extra blank line.
2) discretionary hyphens coming through from InDesign all the way into the HTML
files which are ignore in browsers, but appear as dashes/hyphens in Livecode
fields after textDecode… or sometimes appear after I run scripts as:
""
3) the old ligature double characters, in particule fi "fi" tied together.
fi In Livecode, this just disappeard… instead "we find" I see "we nd" in
the field. I suspect the character is actually there, but the font can't
render it,so the LC field is just white space in that location.
fulfillment
Try as I might, I am unable to target these characters viaLC script…it's as if
what I see in BBEdit and in the source of the page in the browser is not what
gets imported using "put url " … in any form… in LC. using
put url ("file:/" & "part1_ch3.html") into tText ## no search and replace I
attempt will work
using binfile or textDecode before insertion into the variable also doesn’t
work.
Here is my script (latest iteration on many variants all of which don't get the
job done)
global gBookFilesLocation
on mouseup
palette this stack
set the defaultstack to the topstack
put fld "TOC" into tToc
repeat for each line x in tToc
set the itemdel to "."
put item 1 of x & "-clean.txt" into tFilename
put the uBookFilesLocation of this stack into tPath
#put url ("file:" & tPath & "/ops/xhtml/" & x ) into tText
put url ("binfile:" & tPath & "/ops/xhtml/" & x ) into tText
put textDecode(tText,"UTF-8") into tNewText
# check for discretionary hyphens
if tNewText contains "" then
answer "Yes got unicode soft hyphen string" with "OK"
exit to top # this never fires ...
end if
## Attempts to replace here:
replace "¶" with (cr & cr) in tNewText # never happens;may need to use
""&cr&""
replace "¶" with (cr&cr) in tNewText # Pilcrow sign for the above char:
U+00B6 old name "Paragraph Sign" --we want an extra blank line.
replace "" with "" in tNewText # soft hyphen
replace "" with "" in tNewText # Soft hyphen - replace with nothing
replace "" with " " in tNewText
replace "" with " " in tNewText
replace "" with " " in tNewText
replace " " with " " in tNewText # remove double spaces create by breaks
following a space.
put textDecode(tNewText,"UTF-8") into tNewTextOut
set the htmlText of fld "CurrentChapterText" to tNewTextOut
put textEncode(fld "CurrentChapterText","UTF-8") into url ("binfile:" &
gBookFilesLocation &"/_cleanExport1/" & tFilename)
end repeat
end mouseup
I tried, in another text processing stack I have, just to go direct from file
into script/vars and then out to file without going thru a field… that's no
better.
Any clues on how to approach this?

TextDecode JSON array
Here's a test sample of some UTF8 I get back from a server:
{"UserID":48,"UserName":"Eduardo Ba\u00f1uls","UserLoginName":"ebanu"}
If I run textDecode(,"UTF8") on it, I get it back unaltered.
Does anyone recognize the text encoding? It doesn't seem to be UTF8.
If I then run JSONToArray on it, I get a LC array and the name is
changed to this:
Eduardo Bañuls
And when I run textDecode on *that* it comes out right:
Eduardo Bañuls
So what's the first string? JSONtoArray seems to recognize it. I'd like
to decode the JSON array completely before passing it to JSONtoArray. If
I can do that, I don't have to loop through all the array keys, decoding
each one individually.

So LC should recognize it without alteration I'd assume, but it doesn't.
Probably the leading "\u"? I'm still not sure how to handle that.

That is UTF-8. I've seen older versions of Ruby on Rails would use escape

Hi Jacque,
This is valid JSON (and also valid ASCII). In JSON, any character in a
string may be encoded in the form \u where is the 4-digit
hexadecimal representation of a Unicode codepoint. No textDecode()
operation is required.
JSONImport() handles this correctly.
1) Create a stack with a field and a button
2) Put the text above into the field
3) Set the script of the button to:
> local tJson
> put JSONImport(field 1) into tJson
> answer tJson["UserName"]
4) Enter browse mode and click the button
You will get an answer dialog displaying "Eduardo Bañuls".

Using LC server to check for existence of mp3 on our web server?
Hi, On-rev.com hosting, using LC server to present a list of our AM/FM radio programs for people to listening to on-demand. Out of a month's 20 programs, 3 or 4 might not get uploaded due to copyright issues, etc. Also, mp3's are not on the on-rev.com server, but another hosting service we use as well. Filenaming is standardized, so I know the list of programs. I want to hit the server, if the mp3 files exists, present it as an program not available" message. If I wanted to check on the existence of a small text file, it would be fast enough for me to just get it, put it into a variable and see if the variable has anything in it. But mp3's are too big, so too slow. Locally, I would simply write "if there is a file 'filename'..." -- what's the equivalent command for checking on existence of a file on a server? Thanks in advance.
