Android build executable on test device fails

[Nicolas Cueto via use-livecode]

Testing on an Android device, the "Standalone builder progress" window
shows first "Building classes" and then for a brief moment "Building
executable", after which an error window reads "Unable to build app for
testing: could not open module file".

Searched the forums but no mention at all of this problem.

You could try to use (respects UCI word boundaries):

if the num of trueWords in myString is 0

Works here in LC 7 and later.

Re: Identifying empty lines of text

[Phil Davis via use-livecode]

I wonder if the 202 value would disappear if you did this:

   put textDecode(the clipboarddata["text"], "utf8") into field 1

I don't know the answer, just putting it out there.

Identifying empty lines of text

[David Epstein via use-livecode]

I use “the number of words in myString = 0” to test whether a line of text 
appears empty, since I want a line with only space characters to be understood 
as empty.
But a line of text I pasted from elsewhere contained an invisible character 
whose charToNum value is 202, and this was counted as a word by my script.
Is there a better way to test for a line of text that has no visible characters?

That is precisely why we are having this conversation.  An assumption was
made that creating an HTML version of plain text was needed for the
clipboard.

Non- starter. Can't make assumptions about the end user's intent. What if what 
he was copying was SUPPOSED to have double line breaks or carriage returns? The 
complaint would be that LC was taking liberties with user's data!

Re: Getting datagrid content from other stack in Standalone

[Bob Sneidar via use-livecode]

The last one is possible. As far as substacks getting moved and breaking 
references, the Standalone Builder takes that into account I believe. Also, if 
the stack files are contained in the folder the SB creates for them, I 
*believe* that the engine will upon failing to find a stack reference, check 
that folder, otherwise the SB would have to change the references in the code 
wherever it found them, and that wouldn't account for stack paths stored as 
properties. I'm pretty sure the engine resolves those things on the fly.

Re: Getting datagrid content from other stack in Standalone

[Bob Sneidar via use-livecode]

If the script of an object is running, the stack it belongs to is open. If you 
reference an object in a closed stack (correct me if I am wrong) LC will load 
the stack the object belongs to into memory.

Re: Problem pasting from Livecode to Mac Mail

[Brian Milby via use-livecode]

So there are 2 issues with how LiveCode is handling placing text onto the
clipboard:
- converting plain text to HTML on the clipboard
- using  tags for each line break when converting to HTML

I’m not sure of the reasoning behind the first issue. I understand wanting
to have the native LC format for rich text, but if placing plain text on
the clipboard, I think that the user wants plain text and not HTML.

The second issue may take some additional thought/discussion. Looking at
the code, it uses the  tag to wrap attributes, so eliminating it
globally isn’t an option. Magic happens here:

fieldhtml.cpp / export_html_emit_paragraphs
fieldh.cpp / MCField::doexport

If it was changed to use  for single line breaks and only assuming a
paragraph when there are 2, that would probably take care of it in most
cases. Paragraphs are split by /n here (internal LC styled text
representation):

fieldh.cpp / MCField::texttoparagraphs

Still digging...

Re: Getting datagrid content from other stack in Standalone

[Mike Bonner via use-livecode]

Would this work with a stack on disk that hasn't been opened yet?

Definitely stealing your functions thx. :)

Oh, as to the OP, my first thought on why it wasn't working, is that the
stack wasn't open (hence the need to address it's on disk location), but
another thought occurred to me.  I'm wondering if the standalone auto
inclusions can be affected by moving substacks into separate stackfiles
 Perhaps the datagrid support libraries aren't being included?

Re: Getting datagrid content from other stack in Standalone

[Bob Sneidar via use-livecode]

Don't you mean:

put the dgdata of grp 1 of CARD 1 OF stack "path/to/dgstack.livecode" into 
tDataA

If you are going to be using full paths for this, I recommend using my fine 
functions getParentCard() and getParentStack(). 

function getParentCard pObjectID
   put offset("card id", pObjectID) into tStartChar
   put char tStartChar to -1 of pObjectID into tCardID
   return tCardID
end getParentCard

function getParentStack pObjectID
put offset("stack ", pObjectID) into tStartChar
put char tStartChar to -1 of pObjectID into tParentStack
return tParentStack
end getParentStack

As you can see they are very basic. Pass a long id of the calling object and it 
returns the long card ID or the long name of the parent stack. Now you can do 
this:

put getParentCard(the long id of me) into tThisCard
put the dgData of grp 1 of tThisCard into tDataA

Server-side xml validator anyone ?

[jbv via use-livecode]

Hi list,
I have several server-side LC scripts that transform text and data
uploaded by end users on web pages into xml to be stored in a database and
used later in other web pages or apps.
The problem is, despite all the correction scripts I have added, that
sometimes the uploaded content corrupts the xml structure. This happens
for instance when some weird UTF-8 text is uploaded.
Is there a ready-to-use piece of code that would check the conformity of
some xml data that I could include in my LC scripts ?

Thanks in advance,
jbv

Re: Problem pasting from Livecode to Mac Mail

[Peter Reid via use-livecode]

Sorry, forgot to change Subject in previous posting...

Hi Richard

I found this problem was particularly annoying when trying to extract info from 
vCards exported from Contacts on the Mac, so I developed a tiny app in LC 
called vCardClipper.

I've put together a web page about this app together with download links to a 
Mac App and the source code.  Here's the link to this web page, help yourself:

https://www.reid-it.co.uk/downloads/downvcclip.htm

The key is to paste HTML format text into Mail replacing RETURN with "" and 
replacing spaces with "". The code is in the following handler (which is 
in the stack script):

on loadClipboard pPlainText, pPasteMode
   -- pPasteMode: HTML or text
   set itemDelimiter to "."
   put item 1 of the version into tLCversion
   lock the clipboard
   if tLCversion >= "8" then
  -- for LC 8.x or later:
  set the fullClipboardData to empty
  switch pPasteMode
 case "HTML"
put pPlainText into tHTMLtext
replace return with "" in tHTMLtext
replace space with "" in tHTMLtext
set the fullClipboardData["HTML"] to "" & tHTMLtext & ""
break
 case "text"
set the fullClipboardData["text"] to pPlainText
break
  end switch
   else
  -- for LC 7.x or earlier:
  switch pPasteMode
 case "HTML"
put pPlainText into tHTMLtext
replace return with "" in tHTMLtext
replace space with "" in tHTMLtext
set the clipboardData["HTML"] to "" & tHTMLtext & ""
break
 case "text"
set the clipboardData["text"] to pPlainText
break
  end switch
   end if
   unlock the clipboard
end loadClipboard
