If a tree falls in the forest and nobody is there to hear it, does it make a 
sound?

Or, If a man speaks in a forest and there is no woman around to hear him, is he 
still wrong?

Re: What's the syntax to check if a local folder exists?

Sure -- what you get instead of true or false is "damn right there ain't no

One technique is to replace a repeating string that sets off pieces of content 
you want to isolate with a single character, e.g., 

   replace "" with divChar in tText

then use that as an itemdelim or linedelim to access "item n of tText" or "line 
n of tText"

You need to make sure that the characters you will use as delimiters are not 
found in the text. For HTML, all you have to do is use any higher-ASCII 
characters. Here is a way of doing that that actually works also with text that 
may contain high-ASCII characters, but you can use this fine to parse HTML text.

-

local lineChar, itemChar, cellDivChar
local textBlockDivider, frameDivider -- extras as needed

on assignDelims tText
   put getdelimiters(tText) into delimArray
   -- an array of high-ASCII characters not found in tText
   put "lineChar,itemChar, cellDivChar" into delimList
   -- add more if you want, these are 
   put the number of items of delimList into nbrDelimsNeeded
   repeat with i = 1 to nbrDelimsNeeded
  put delimArray[i] into tDelim
  if tDelim = empty then
 answer "Could only assign" && i-1 && "out of" && \
 nbrDelimsNeeded & "!"
 -- in case you have high nbrDelimsNeeded
 -- or tText contains lots of unusual characters,
 -- and the list of allowable delims is very short
 exit to top
  end if
  do "put tDelim into" && item i of delimList
   end repeat
   
   -- you can also do this manually, for one-off parsing jobs
   -- should check that delimArray[n] is not empty if in doubt
   -- (declare script local variables as needed)

   -- put delimArray[4] into textBlockDivider
   -- put delimArray[5] into frameDivider
   -- etc
end assignDelims

on getdelimiters tText
   if tText = empty then return empty
   put "ßπ∆ƒµ¡™£¢∞§¶ªç≈…æ∑ø©®Ω" into charList
   -- don't know if this will show well in all email clients
   -- it's a string of high-ASCII characters
   put 0 into tCount
   repeat for each char tChar in charList
  if tChar is in tText then next repeat
  add 1 to tCount
  put tChar into delimList[tCount]
   end repeat
   return delimList
end getdelimiters

Then you can do things like:

   replace cr with empty in tText
   -- html ignores cr's, and extraneous returns may complicate things
   replace "" with lineChar in tText
   replace "" with 
cellDivChar in tText
   -- or whatever the tag string is for this particular table

then:

   set the lineDelimiter to lineChar
   set the itemDelimiter to cellDivChar
   repeat for each line tLine in tText
  repeat for each item textRun in tLine
  -- do more parsing stuff here:
  -- now you can work on each block textRun
   end repeat
   end repeat

This helps to pare down some of the HTML formatting/tagging so as to use LC's 
powerful chunk manipulation to extract the content you want.

Don't know if anyone has already tackled this kind of thing in LC, but it 
should be fairly easy to do. (Whether the algorithms actually work to 
distinguish different authors is something I know nothing about.) The gap 
between pairs of a given word, in particular, is nearly trivial. The question 
would be speed, and since LC is blindingly fast at processing text strings, I'd 
be optimistic about that, unless you're talking really huge texts.

Re: System Date/Time Format Problems

There may be a better way, but you might have to use a shell call. Execute the 
following in the message box:

   put shell("man date | col -b")

and look at the options. You can get any format you want, and this way you 
would have full control over date display format in LC.

Try this, perhaps?

on mouseup
   put 1 + (word 4 of the selectedchunk) into saveMark
   -- this will be the first character after the selection
   put length(char saveMark to -1 of fld "myUnicodeFld") into savedLength
   put (-1)*savedlength into savedLength

One way to "turn that off" is to group all the controls on the card, then set 
the traversalon of the *group* to false. You can still enter text in any 
individual field, but you don't get an unintended insertion point in the first 
(lowest layer) field when the card opens. I use this a lot, since I'm one of 
the people (can't really call myself a true developer) you might have seen 
gibbering in the street

Here's what I have in one of my fields, where I am creating links from time to 
time:

on mouseup
   -- select the text you want to turn into a link
   -- then control-click the selectedText
   -- mouseup is sent when control-clicking in an unlocked field
   if the environment <> "development" then pass mouseup
   if $user <> "pmbrig" then exit mouseup
   -- prevents other users from modifying links
   if the controlkey is down then
  put the clickchunk into cc
  put the clicktext into ctxt
  put the linktext of cc into linkT
  -- in case you are modifying an existing link
  ask "Linktext for '" & ctxt & "'?" with linkT as sheet
  put result() into r
  put it into linkT
  if r = empty then
 if linkT = empty then
-- to remove link & set the text back to normal style
set the forecolor of cc to empty
set the textstyle of cc to empty
set the linktext of cc to empty
 else
set the forecolor of cc to blue
set the textstyle of cc to link
set the linktext of cc to linkT
 end if
  end if
   else
  pass mouseup
   end if
end mouseup

I made a simple stack to generate strong passwords. Options include choosing 
length of PW and whether to use punctuation characters or not. Should be pretty 
robust. Using this kind of password really means you have to have a secure 
repository for your passwords, since random passwords are rarely easy to 
remember. (Here is a plug for Bill Vlahos' InfoWallet!)

Re: AW: security code number generation

[Peter Brigham MD]

You could include (without telling the user) the contents of $user as part of 
what is inputted to generate the code. This would make it more secure but cause 
problems with portability, etc. I agree with the later posts pointing out the 
trade-offs between security and user-frendliness. Consider your decisions in 
that light.

I use a frontscript -- wholesale is better than retail:

on closefield
   setDirty
   pass closefield
end closefield

on setDirty tf
   if tf = empty then put true into tf
   put the version into v
   replace "." with empty in v
   if v < 453 then exit setDirty
   -- version must be 4.5.3 or higher,
   -- or you just create a new customprop
   set the modifiedMark of stack "myStack" to tf
end setDirty

If you want to exclude certain fields, use a customprop to mark fields that 
shouldn't trigger setDirty when edited:

   set the the dontFlagDirty of fld "excludedFld" to true

Then in the closeField handler in the frontscript, insert as the first line

   if the dontFlagDirty of the target <> true then pass closefield

Changes other than field content that should be saved (radiobuttons or 
checkboxes, etc) can be handled, eg, with a mouseup handler in the frontscript, 
and suitable checks on the target. (Pass the mouseup!)

I also do:

on preopenstack
   set dirty false
   ...  ...
   ...
end preopenstack

Re: Where does survive the inventive user ?

[Peter Brigham MD]

Just to let you know that you're not alone -- I'm a similar LC user, started 
with HC (actually bought and read through Danny Goodman's book even before I 
bought my first Mac), developed a set of stacks to manage my clinical notes, 
incorporated more and more features, moved it over to LC a number of years ago, 
at which point with all of LC's capability the feature set grew even larger, 
now a full-fledged practice management tool, with 45 substacks, over 32,000 
lines of script, couldn't manage without it. I'm not a programmer, just picked 
it up on the side. I have no idea how you market to people like me, but I 
suspect there are lots of us scattered around.

Re: User Interface Question

[Peter Brigham MD]

And it's much better not to lock the cursor and then change it. Locked cursors 
have a way of sticking if the handler to unlock the cursor somehow misses. 
instead, don't lock anything, just set the defaultcursor to hand, then set it 
to empty when done. I usually have this in my stack script:

on mousemove
   put the target into tTarg
   if the name of the target contains "button" then
  if the tool contains "browse" then
 set the defaultcursor to hand
  end if
   else
  set the defaultcursor to empty
   end if
   pass mouseMove
end mousemove

on mouseLeave
   set the defaultcursor to empty
   pass mouseLeave
end mouseLeave

Re: How do I remove part of a path?

[Peter Brigham MD]

When you replace item 4 of tStr with empty, you don't delete the item itself, 
you just make the item empty:

put "a/b/c/d/e/f" into k
set itemdel to "/"
put "" into item 4 of k
put k

  -> a/b/c//e/f

What you need to do is delete the item itself:

put "a/b/c/d/e/f" into k
set itemdel to "/"
delete item 4 of k -- note the change
put k

  -> a/b/c/e/f

furthermore, when I click to join and get the fields to fill in personal info, 
which I did not fill in, and I click "terms and conditions" (which I do before 
I join anything these days), nothing happens. No terms and conditions. Doing a 
search on "terms and conditions" gives me a list of articles but no telecomtv

nothing else. So needless to say, I ain't joining.

Re: Nine digit zip codes

[Peter Brigham MD]

FWIW, I have a handler that feeds the address to Google Maps and then  
parses the HTML to extract the 5-digit zip code. Takes less than a  
second unless the traffic is high. I'm pretty good at text parsing but  
know very little about XML and GET/POST commands -- I had to look  
around to find a webpage that I could post the address using straight  
HTML rather than Java or SQL or whatever, and Google Maps was it. Only  
a 5-digit zip, though.

Re: Cursors in a Revlet

[Peter Brigham MD]

FYI, though I know little about revlets, if you are setting cursors on  
a stack running on the desktop (in the IDE or as a standalone), it  
will work much better to set the defaultCursor. I used to lock the  
cursor and set it to something but ran into intermittent problems with  
it not unlocking. Try this in a stack script, so that the cursor  
changes to hand for all buttons and reverts reliably when leaving the  
button:


on mouseMove
   -- more reliable than mouseEnter
   if the name of the target contains "button" then
  set the defaultcursor to hand
   else
  set the defaultcursor to empty
   end if
   pass mouseMove
end mouseMove

on mouseLeave
   set the defaultcursor to empty
   pass mouseLeave
end mouseLeave

Re: Finding local minima and maxima of a graph

I had thought of using a moving average to find a slope of zero and

I've used stackoverflow to have a look and apparently the problem is

Any suggestions for fitting to a function, using the graphing

Re: PDF ?

If you only want to fill in the stamp and then print the result, what  
I do is import the pdf as an image, overlay fields wherever I need  
them, then fill them in by script, and print the result. If you want  
to export it instead of printing it, you could take a snapshot of the  
result and export that as jpg or, I guess, as a pdf file, though I'm  
not sure about the latter, maybe use the pdfLib for that.

We simply want to 'stamp' an existing document with a customers  
unique ID and details. The area of the document to be stamped will  
be blank space on each pageat a defined location (footer or  
header area, for example) and requires no interaction with the  
existing content.


From there, just a re-export of the PDF would be required.

What do you think?

Cheers,

While I have written a library to create new PDF files from  
scratch, by script, I'm not sure where to begin taking apart an  
existing PDF file and modifying its content.
The structure of a PDF file is completely unlike Word DOC or RTF  
files. Word processing files are structured around a flow of  
paragraphs, sentences and words. PDF files are a set of low-level  
instructions (draw a line here, draw this bit of text there, now  
switch to font 'Times', set the drawing color to 'red', etc.) and  
there is no rigid flow structure.
More precisely, PDF has no concept of paragraphs - you're at the  
mercy of the producing application printing each bit of text in the  
'right' order to ease extraction. In fact, PDF doesn't even have  
text styling concepts other than 'font'. You want an underline?  
Draw it yourself.
In fact, it's so complicated that the selection of text in Adobe  
Reader or Apple Preview is based on OCR (optical character  
recognition) algorithms: we know there's a bit of text here, and  
that other bit of text has the same baseline, so that could  
actually be a single line of text in the user's mind - let's select  
both!
So if you're looking to read an existing file, and modify the  
content - such as replacing placeholder text and expecting the  
whole flow of the text to update along with it - you have your work  
cut out for you.
One feature I have been working on, is the ability to open an  
existing PDF file, and use pages from it as a background on top of  
which you draw additional elements. In that scenario I'm not even  
really tweaking the content, and this is presenting its own  
gotchas...

You are missing a "then" in the image mouseup script. If this script

Any clues?


Where is the focus? If there is an insertion point in a field, or any  
other control has traversalOn = true and has the focus, and that  
control has a commandkeydown handler, then the commandkeydown message  
will be caught there and could be trapped.

You get the same with any build-in command, e.g.:

Whether this is a weakness in the engine or the documentation is a

Re: Recursion warning: what's the owner of a background?

[Peter Brigham MD]

On Dec 23, 2010, at 6:34 AM, David Bovill wrote:

This one just caught me out. I have a script that checks a property  
of it's
owner and returns the value. Specifically it checks the owner for a  
property

of the same name to see when the local value is empty to see if it is
defined higher up in the object hierarchy. I thought this would be a  
safe

way of implementing object oriented stuff.

But you get recursion when the control is a background, because the  
owner of
a background is the card the background is on, but the card is  
actually
below the background in the message hierarchy, so the background  
script gets

triggered again when you look for it in the backgrounds owner.

A recursive tongue twister maybe - but just remember a background's  
owner is

itself in scripting terms!


On the other hand, this utility function works fine for me:

function masterBG theObjectRef
   put the long id of the owner of theObjectRef into onr
   if word 1 of onr = "card" then
  return theObjectRef
   else
  return masterBG(onr)
   end if
end masterBG

It returns the highest level group a control belongs to. I have a  
stack with two major backgrounds (switch between making one or the  
other visible with a button). In my custom find function I need to  
know which master background the foundfield is part of, and it may be  
nested in lower level groups, so this tells me which bg to show when a  
string is found, and it works reliably without the recursion problem  
above.

the locktext if you work with list fields a lot, so that the usual

  set the writable of the target to not the writable of the target
   else
  pass mouseup
   end if
end mouseup

But you have to add the mouserelease handler below, since clicking on  
a blank line of a list field doesn't send mouseup, it sends  
mouserelease instead.


on mouserelease theBtn
   if theBtn = 1 and "field" is in the target and the \
  commandkey is down and the shiftkey is down then
  set the writable of the target to not the writable of the target
   else
  pass mouserelease
   end if
end mouserelease

The only problem with the final result is that if you set the  
listbehavior of a field to true, then toggle the writable, then set  
the listbehavior of the field to false, it is still flagged in the  
customprop as being a list field, and when you toggle writable again  
it will revert to being a list field again. So you have to delete the  
customprop by hand to get it to behave correctly. This could be solved  
with a preopencard handler as follows:


on preopencard
   if "field" is not in the target then pass preopencard

Re: RevOnline: New version of Shell Command Help

So, no way of decoding this easily, huh? If you do a char by char pass  
through the text and replace every doubled letter with its single,  
then you'll get sily comands How do the "geek apps" manage to

Re: When is a Word not a Word?

Got weird things going on with the wordoffset function.  The code is:

if field Selection contains xyz and myline contains abc def xyz,

if field Selection contains xyz and myline contains abc def  
"xyz" (xyz in double quotes this time), wordoffset returns zero.


I've tried this with all combinations of casesensitive and  
wholematches true and false.


According to the dictionary, "A word is delimited by one or more  
spaces, tabs, or returns, or enclosed by double quotes" so why isn;t  
"xyz" recognised as a word?


Pete Haworth


Word 3 of
   abc def "xyz"
is
   "xyz"
not
   xyz

The business about "enclosed in double quotes" refers to the (to my  
mind) puzzling convention in RC, dating back to the old HC days, of  
considering anything in double quotes to be one word. So, word 3 of

   abc def "ghi jklmno"
is
   "ghi jklmno"
(with the quotes included). There was a debate about the merits of  
this convention a while back -- search the archives.


But you might have wholematches set to true.

If you do:
   put "abc def ghi" && quote & "xyz" & quote into tSentence
   put "xyz" into tWord
   put s & cr & wordoffset(tWord, tSentence)
then you get
   abc def ghi "xyz"
   4
unless the wholematches = true, in which case the wordoffset returns 0.

Re: Re: saving data in a standalone before quit
(Was Re: (mac) application menu)

Peter,

When you use the Quit menu item, Mac OS X sends an event to  
Revolution. You can catch this message with the AppleEvent handler or  
the shutdownRequest handler. On Mac OS X, I prefer to use the  
AppleEvent handler most of the time.


If you use either the AppleEvent handler or the shutdownRequest  
handler without a pass command, the application will not quit by  
itself (you can also lock messages and issue the quit command).


When you press command-Q, the Quit menu item should work just like  
when you use the mouse to select this menu item and you can catch the  
AppleEvent and shutdownRequest messages again. However, your script  
may catch the commandKeyDown message. If you don't pass this message  
with the pass command, your application may not quit.


There are versions of Revolution that don't pass the commandKeydown  
message because of a bug. There are also versions that don't pass the  
AppleEvent message.


If you are using Rev 2.8.1, problems with quitting are probably due to  
a script.

The field needs to have focus first.


If the insertion point is in the field then it has focus, right?

I just double-checked: created a new mainstack, put a new field in it,  
put some text into it, and put this in the field script:


on selectionchanged
   beep

and when I click anywhere in the text to change the insertion point I

I finally checked on this, and you're right, selectionChanged isn't  
sent in an unlocked, non-list field. Instead, arrowkeys are treated  
as keypresses like any other character, so you need to trap key- 
related messages instead.


If the field is a list field, then arrowkeys do trigger  
selectionChanged.


That makes sense, since that is the whole point of list fields, right?  
to be able to select a line or lines for various purposes.


I'm always happy with any element of consistency -- we live in a

Jacqueline is correct. The fields make up a mixed up paragraph. I  
have it working where it lines up the mixed up fields nicely across  
and down the window. The user is to put the fields back in order. If  
one of the fields is a pixel lower on a line, or when the user has  
to start another line of fields below the first, there is a problem.  
I like your idea Jacqueline about the drop down fields but I'm  
afraid not being able to see all parts of the paragraph will make it  
too challenging at a beginning level.


I thought I could make each row of fields on the window a separate  
group. This could be done when the stack creates the fields for each  
line. However, that would mean that I would only have mixed up  
content for each line going across, and I couldn't make the user  
drag fields between lines. I want more mixed up flexibility...


Maybe I could have the fields snap to alignment some how when the  
user checks their answer and before the sort...but that still would  
not eliminate the issue with the subsequent lines of fields and  
their order over all...


LiveCode doesn't do character recognition does it (OCR)? I could do  
a screen capture, covert the pict to text and then check its  
content ;-) ...


Hmmm? What if the user drags the fields over a target...the target  
could "suck the text" out of the field and spit it out in another  
field. (This essentially would be eliminating the user to type out  
their words on a keyboard.) However, how would I handle the user  
wanting to change their order? Could the text chunks they drag into  
the target be "special chunks" that act as quasi buttons that when  
clicked on by the users recreates that specific chunk text and  
deletes itself from the answer field? The user could still drag  
their fields around on the screen to order them the way they want,  
and then just drag them into the target one at a time. What do you  
think? This seem doable?


Sure. Create a number of small text fields with behavior set to a  
behavior button and a target button. In the behavior button script set  
up mousedown and mousemove handlers to handle dragging (see the  
archives for how to do this), and in the mousemove handler include a  
'if the mouseloc is within the rect of btn "target then eatme" '. Then  
the on eatme handler in the card script takes the text of the target  
field and appends it to the display field and deletes the target  
field. In the display field, put a mouseup handler that hilites the  
clicked line briefly for user feedback then creates a new small field,  
sets it behavior to the behavior button, loads it with the line text,  
then deletes the clicked line.


If that's what you want to do. Not sure why you prefer this to just  
dragging the lines around to reorder them in the display field. I  
guess it's a game that you have in mind?

Look at the Google API. I just paid attention to the case of inputting

Ah, sorry, I forgot. A couple of other utility functions from my

function offsets str,ctr

   -- if none found, returns 0
   put "" into mosList
   put 0 into startPoint
   repeat
  put offset(str,ctr,startPoint) into os

   return mosList
end offsets

-- To find the last of multiple matches for str in ctr, use
--   item -1 of lineoffsets(str,ctr)

First, the traversalon of the button must be false or the selection in

Re: Sample code for reading a CSV file

First, thanks to everyone who replied, but especially to Nosanity.  
Your code reminded me that you can effectively tell when you are  
inside an encapsulated bit of data by an odd/even count of the  
encapsulation character. So, for anyone who wants it, here is a  
generalized function that I just wrote to parse a CSV file,  
regardless of the field or record delimiters (commas, tabs or  
whatever) and to deal with encapsulation appropriately.


This assumes you read the entire CSV file into a variable you pass  
into pData, so a call would look like:


put csvToArray(myEntireCSVData,return,comma,quote) into myDataAsArray

I have tested it a bit in the last 30 minutes and it working in the  
cases I tried, but did not test exhaustively and have not checked  
performance on large datasets. If any one uses this and run into an  
issue, please let me know.


function csvToArray pData, pRecordDelimiter, pFieldDelimiter,  
pEncapsulationDelimiter

 local tReservedRecordDelimiter, tReservedFieldDelimiter, tArray

 # Initialize the temporary record and field delimiters. Change  
these if your CSV file may contain them.
 put charToNum(1) into tReservedRecordDelimiter; put charToNum(2)  
into tReservedFieldDelimiter;


 # Step 1: Replace any Record or Field delimiters that are  
encapsulated with temporary characters

 set itemdel to pEncapsulationDelimiter
 repeat with i = 1 to the number of items in pData
   if trunc(i/2) = (i/2) then
 replace pFieldDelimiter with tReservedFieldDelimiter in item i  
of pData
 replace pRecordDelimiter with tReservedRecordDelimiter in item  
i of pData

   end if
 end repeat

 # Step 2: Replace all occurances of the encapsulation delimiter
 replace pEncapsulationDelimiter with empty in pData

 # Step 3: Parse records and fields into the array, replace any  
occurances of the reserved record and field delimiters for each  
element

 set itemdel to pFieldDelimiter
 set lineDel to pRecordDelimiter
 repeat with i = 1 to the number of lines in pData
 repeat with j = 1 to the number of items in line i of pData
get item j of line i of pData
replace tReservedRecordDelimiter with pRecordDelimiter in it
replace tReservedFieldDelimiter with pFieldDelimiter in it
put it into tArray[i][j]
 end repeat
  end repeat

  # Step 4: return the array
  return tArray
end csvToArray


Here's an extension of your handler that will find appropriate  
reservedDelimiters that do not appear in the csv text, so you don't  
have to hope that numtochar(1) and numtochar(2) are not in the data:


function csvToArray pData, pRecordDelimiter, pFieldDelimiter,  
pEncapsulationDelimiter

   local tReservedRecordDelimiter, tReservedFieldDelimiter, tArray
   # Initialize the temporary record and field delimiters. Change  
these if your CSV file may contain them.


   put getDelimiters(pData) into tDelim -- ## see below
   put numtochar(line 1 of tDelim) into tReservedRecordDelimiter
   put numtochar(line 2 of tDelim) into tReservedFieldDelimiter

# Step 1: Replace any Record or Field delimiters that are  
encapsulated with temporary characters

set itemdel to pEncapsulationDelimiter
repeat with i = 1 to the number of items in pData
 if trunc(i/2) = (i/2) then
  replace pFieldDelimiter with tReservedFieldDelimiter in  
item i of pData
  replace pRecordDelimiter with tReservedRecordDelimiter  
in item i of pData

 end if
end repeat

# Step 2: Replace all occurances of the encapsulation delimiter
replace pEncapsulationDelimiter with empty in pData

# Step 3: Parse records and fields into the array, replace any  
occurances of the reserved record and field delimiters for each element

set itemdel to pFieldDelimiter
set lineDel to pRecordDelimiter
repeat with i = 1 to the number of lines in pData
   repeat with j = 1 to the number of items in line i of pData
 get item j of line i of pData
 replace tReservedRecordDelimiter with  
pRecordDelimiter in it
 replace tReservedFieldDelimiter with pFieldDelimiter  
in it

 put it into tArray[i][j]
   end repeat
 end repeat

 # Step 4: return the array
 return tArray
end csvToArray

function getDelimiters tCSV
   -- return 2 non-printing ASCII characters not found in the  
variable tCSV

   put "1,2,3,4,5,6,7,8" into dList
   -- could use other non-printing ASCII values
   put false into foundOne
   repeat with i = 1 to the number of items of dList
  put item i of dList into testNbr
  if numtochar(testNbr) is not in tCSV then
 put true into foundOne
 put testNbr into delimOne
 exit repeat
  end if
   end repeat
   if not foundOne then

Best to not lock and unlock the cursor but rather use:
   set the defaultcursor to 1005
on mousemove (occasionally with rapid mouse movement the mousenter

and then
   set the defaultcursor to empty

I used to lock the cursor then unlock it, but then sometimes the  
cursor stays locked and it's very annoying to the user.


Can you use any png for a cursor? or are there constraints? I know  
that if you want transparency you need a png with alpha channel -- a  
jpg will give you an opaque square with your cursor inside it. I seem  
to remember having to do some tricks with the png image before trying  
to use it as a cursor

Well said.

And sometimes lengthy deeply-nested IFs are good candidates for a  
switch block.


I once stumbled across two tips about code style that have been very  
helpful:


1. If a given function has nested IFs more than three levels deep,  
it may be a good candidate for breaking it up into smaller functions.


2. If a function is longer than can be viewed in one screen, it may  
be a good candidate for breaking it up into smaller functions.


Sometimes those can't be applied for sound practical reasons, but  
where they can oh boy does it make code more readable.


I grapple with this all the time. My status with LC is "dedicated  
amateur," so I may not use the best practices, but One other  
consideration is breaking out a chunk of code when it needs to be  
reusable, but this is not without problems too.


I have a number of text-processing handlers that parse out various  
context-sensitive options for constructing pop-up menus, inserting  
text strings that are themselves constructed using various if-else- 
then scenarios, etc, and these tend to result in very long handlers  
with lots of conditional branching. I keep trying to break up my long  
handlers into smaller chunks. What I run into is that to do this I  
often face trying to construct functions that require 8-10 parameters,  
which are cumbersome to call, since you have to keep careful track of  
the order in which to list things in the calling statement. Whereas  
within a long handler I can make use of multiple variables that  
already contain pieces of data and make use of them without having to  
pass them anywhere. I usually end up splitting off a chunk of code  
into a function when I find that I need to use it a number of times in  
different contexts. I end up with some handlers and functions that  
require lots of parameters but can be called from many different  
buttons, fields, menus, etc., in which case living with a long  
parameter list is well worth it for the flexibility.


I have not yet found very many tricks to avoid long multivariable  
handers, given that I'm trying to provide extremely context-sensitive  
behavior. I do end up with some very sophisticated features, eg,  
constructing a prescription for printing or just logging, checking to  
ensure the med is not in the patient's allergy list, checking if a  
telephoned prescription is a controlled drug and therefore needs a  
faxed copy and if so then setting up a reminder to fax the copy (but  
only if there is a fax number listed for the patient's pharmacy, if  
not, then a reminder to get the fax number), logging the prescription  
in the notes field and the current meds list, calculating and noting  
the expected date the med will expire, loading the med into the  
prescription history, and checking to see if a serum blood level is  
(a) necessary and (b) overdue -- all with a mouseclick on the med  
listing line, and a couple of keypresses.


It turns out that it is hard to break this kind of thing down into one- 
page handlers, but I keep trying. I tend to use switch blocks for long  
complex conditionals and if-else-then for the shorter conditionals,  
but I'm fairly sloppy about when I do one or the other. But I almost  
always construct if-else-then structures using the long form -- I  
heartily agree that it is much, much more readable.

new trick, for me

[Peter Brigham MD]

Just discovered a trick I didn't know about. This is in the IDE, BTW.  
I needed to have the first card of one of my stacks as the current  
card, while I do something from another stack (a utility stack). If I  
"go card 1 of stack " then the stack  comes to  
the front, but I want to keep the utility stack as the topstack, so  
even following this by "go back" or some such looks messy on screen.  
Instead, I can do this:


   set the currentcard of stack  to \
   the short name of card 1 of stack 

and it all happens in the background.

Probably others knew about this, but I didn't, so I'm posting it for  
those like me for whom it is a new trick.

Re: new trick, for me

[Peter Brigham MD]

It appears not to trigger openCard.

FYI, the reason that I needed to do this is that I am trying to do  
something with long id's and found what seems to be a bug in how the  
engine handles this. If I do this while on the first card of the stack:


   put the long id of control 76 of card 1 of stack 

I get something like this:

field id 1051 of group id 1045 of group id 1004 of card id 2276 of  
stack "PDdata" of stack 


But if I move to any other card of the stack, and execute the same  
command, I get:


field id 1051 of group id 1045 of group id 1004 of card id 2675 of  
stack "PDdata" of stack 


Note that the card id number in the long id is different, depending on  
which card is current -- despite that fact that I asked specifically  
for "the long id of control 76 of ***card 1*** " both times.


I know that occasionally executing commands via msg box give anomalous  
results, but that appears not to be a factor here.


So I need to be on the same card of the stack every time I fetch long  
id's for controls of that stack, or else my handlers won't work  
properly.


Bug, or what?

No. I don't think it triggers any messages.

"belongs to" is what sense? The owner of the background group is the  
card. Can you say what you mean operationally?



Also try:

send "put the long id of control 76" to card 1 of stack 
get the result
What does that produce?


the result is empty
executing just the first line gives (for some reason) just the short

Re: newbie script question re Find command

On Mar 22, 2011, at 5:31 PM, Timothy Miller wrote:


Hiya,

I guess I never tried to write a script like this before. Thought it  
would be simple... Well, it is simple, probably, just not simple in  
a way that I actually understand.


How do I find multiple instances of a string in a given field of a  
given card and record each foundchunk in a variable, and then stop  
repeating the find command when the last instance is found?


I want to do this in the context of a repeat loop that goes to all  
the cards in the stack in sequence.


Sooo, I also need to know... How do I tell the repeat loop to move  
on to the next card:


- if no instance of the string is found on the card

- and

- after the last instance of the string is found on the card

Hope that's clear.

I understand I'll probably want to nest a repeat loop using the find  
command on each card, with exits when certain conditions are met.  
I'm choking on the details.


I don't need a complete and accurate script. Just the general idea.

Thanks in advance.

Tim (the world's oldest newbie)


It's never too late to be a newbie!   :-)

Here is a function that returns the all the offsets of a string in a  
container:


   function offsets tStr,tCntr
  -- returns a comma-delimited list of all the offsets of tStr in  
tCntr

  put "" into mosList
  put 0 into startPoint
  repeat
 put offset(tStr, tCntr,startPoint) into os
 if os = 0 then exit repeat
 add os to startPoint
 put startPoint & "," after mosList
  end repeat
  if char -1 of mosList = "," then delete last char of mosList
  if mosList = "" then return "0"
  return mosList
   end offsets

Using that, you could first

   mark cards where fld  contains 

then loop through the marked cards and find the full list of  
foundchunks:


   put empty into foundList
   put length(tStr) into strLength
   repeat with c = 1 to the number of marked cards
  put the name of marked cd c into cdName
  put fld  of marked cd c into fldContents
  put offsets(tStr, fldContents) into offsetList
  replace comma with cr in offsetList
  repeat for each line f in offsetList
 put f & "|" & f+strLength-1 & "|" & cdName & cr after  
foundList

 -- use pipe char as delimiter,
 -- or any other char not found in data
  end repeat
   end repeat
   if char -1 of foundList = cr then delete char -1 of foundList

this will give you the full list of foundchunks in the form:

78|85|card id 1016
266|273|card id 1016
13|20|card id 1018
... etc.

and you can parse this by setting the itemdelim to "|" and referring to

   char (item 1 of line n of foundList) to (item 2 of line n of  
foundList) of  of (item 3 of foundList)


to get the chunks.

Not tested, and can probably be streamlined, but you get the idea

I have a button that calls a command - upDateSongs - from its

If upDateSongs is in the stack script everything works fine. However
if it's in the card script the app goes mad - it starts processing  
the

card script from the top, running any code it encounters (my
urlProgress code was at the top of the card script, so it was
triggered by the sending of upDateSongs from the button - hence my
suspicions about libUrlDownloadToFile and urlProgress).

Crazy. And it makes me wonder if my stack is somehow corrupt. Anyone
seen that before?


Never. You may have some duplicate handlers somewhere, or handlers  
that call others you aren't expecting. The best thing would be to  
set a breakpoint near the beginning of the code sequence and step  
into every line until you see what's calling the wayward code.

Re: novice question re "marked" and customkeys

I suspect that using a customproperty of the card would be faster for

Hey dudes,

The "marked" property is so easy to use. "go next marked" and  
"unmark all cards" are so fast and foolproof! Very handy.


I'm wondering if I can somehow define my own versions of "marked"

E.g., in a hypothetical stack, the "marked" of cards 3, 10, 22 and  
99 is "true"


I somehow define my own properties, like "barked" and "darked"

In the same hypothetical stack, the "barked" of cards 1,2, 3 and 4  
is "true"


the "darked" of cards 2,4,6,8 and 99 is "true"

Somehow I could "go next barked" or "go next darked" just as fast  
and easy as I could "go next marked"


In this perfect world, I could "unbark" or "undark" all cards as  
easily as I could unmark them.


I suspect this isn't really possible. I suspect the closest  
equivalent would be to use customkeys and repeat loops, to find the  
next card with a certain value of a certain customkey, and so on. I  
suspect this would be somewhat slower than "go next marked" or  
"unmark all"


The marked of a card resembles a customkey, but I suspect it works  
differently. True?


Is it possible to "go next" to a card with a certain value of a  
certain customKey? Or is it necessary to use a repeat loop to  
inspect the each card until I encounter the customKey and value I  
want?


Is it possible to "set the poodleNose of all cards to empty"? I  
suspect not.


Am I getting this right? Am I missing anything important?

Thanks in advance,

Re: novice question re "marked" and customkeys

[Peter Brigham MD]

"mark cards where..." is very fast and very flexible. Using a  
(possibly hidden) checkbox button should be quite feasible even with  
lots of cards. To "unbark all" you can loop through all the cards and  
set the hilite of the button to false -- be sure not to *go* to the  
cards, just loop through them by reference -- and that should be quite  
fast as well. (set the hilite of btn "barked" of marked card n to  
false) Or, 'mark cards where the hilite of btn "barked" = true' and  
then loop through the marked cards, set the hilite of btn "barked" to  
false, then unmark all cards. Cycling through the cards by reference  
is fast ('set the hilite of btn "barked" of marked card n to false')  
-- always, always, always avoid things like "go card n" within a loop,  
since that takes lots of time.
