Re: How to create a hyperlink within a text field?

[Peter Brigham]

Two ways to do it. The first and simplest is to lock the screen and do 2
finds in succession, as you suggested. The second is to get the lineoffsets
of the link text and scroll to the second occurrence of it. Once you find
the line offset of the actual chapter heading, use "the formattedheight of
line 1 to chapterLineNbr of fld xxx" to get the scroll, and then set it
accordingly.

Re: How to create a hyperlink within a text field?

[Peter Brigham]

A third alternative: split off the chapter title list into another field --
a list field -- and then you can just do a simple find in your text field
when the user clicks in the chapter list field.

Re: list field not getting arrowkey msg

[Peter Brigham]

Unfortunately, I still get nothing with the hilitedlines of me in the
field script. The arrowkey message is not going to the field.

Here's the arrowkey handler in the card script. This works fine but I don't
know why it should be necessary.

on arrowkey what
   put hilitedline of fld notesList into lineNbr
   put the number of lines of fld notesList into totNbr
   switch what
  case left
  case right
 pass arrowkey
 break
  case up
 if lineNbr = 1 then
put totNbr into nextLineNbr
 else
put lineNbr - 1 into nextLineNbr
 end if
 break
  case down
 if lineNbr = nextLineNbr then
put 1 into nextLineNbr
 else
put lineNbr + 1 into nextLineNbr
 end if
 break
   end switch
   set the hilitedline of fld notesList to nextLineNbr
   put line nextLineNbr of fld notesList into listEntry
   put getItem(listEntry, 1, tab) into noteTitle
   displayNote noteTitle
   pass arrowkey
end arrowkey

 What do you get if you put this into the field script:

 on mouseUp

 BTW, I think your arrowkey test needs of the target. Hilitedlines
 without an object reference is probably always empty.

Re: Insertion point problems

[Peter Brigham]

What I do for this is store the selectedchunk in a customprop or a script
local on mouseEnter in the button script that will be doing the pasting.
That way if the mousedown removes the current selection you already have
the info you need. BTW, if you set the traversalon to false for the button,
the current selection should be preserved, which will obviate the need for
this workaround.

 I don’t think there is a way to change this behavior. The workaround that
 comes to my mind is to have an exitField handler in the field which saves
 the selection in a property or global variable that the palette stack can
 access. Alternatively you could have an exitField handler inserted as a
 front script when the palette opens, so that the selection can be saved
 somewhere.

 That is how I would go about this.

Re: Insertion point problems

The difference may be that in Bernd's case the traversalon of the button is
false, whereas in David's case the traversalon of the button is true, which
will void the current selection in the field on mousedown.

  I think there might be several people interested in your stack,
  if you are willing to share :)

 Very - whenever I post a screen shot of a tool I'm working on the
 intention is to make that tool available once it's been sufficiently
 debugged and productized.

 As Steven McConnell reminds us in his book Code Complete, the difference
 in level of effort between a personal tool and a product can be an order of
 magnitude, because with a tool it need only be possible to use it
 correctly, but with a product it should be impossible to use it
 incorrectly.

 My inclination is to give tools and code away at no cost, and sometimes
 even under GPL or other open source licenses when they're a good fit for
 the project's goals, so folks can use them and share them easily.

 Despite my inclinations, however, my accountant reminds me I'm not getting
 any younger, and that I need to remain mindful of little things down the
 road like retirement.

 Like most of us, I toss together ad hoc solutions to help with whatever I
 need to do in my professional work, and now and then things are either so
 trivial that they don't require much polishing to be worth sharing (e.g.
 gZipper and DeskView), or are so necessary to my professional work that
 they're already at least polished enough for others to use (e.g. devolution
 and Flight Recorder).

 But other things require a bit of work to turn them from something useful
 only to me into something that can benefit others as well.

 Looking at the GBs of PBIs (Partly-Baked Ideas) on my hard drives I
 realize some of those would be useful to share - if I can find a way to
 make the time for that away from client work.

 I've considered various forms of crowd-funding, but for small things like
 dev tools it's often more work to set up a campaign and manage it within
 Kickstarter or even IndieGoGo than to just finish the tool itself.

 So while I'm focused right now on meeting some hefty client deadlines, I
 wanted to at least confirm that yes, the code base analysis tool and others
 will become available at first opportunity (devolution 4.0 is very close to
 testable release), and to let you know I'm considering a donation-based
 system to gauge the community's interest in these sorts of things.

 I'm open to other ideas, but at the moment donations seem a good balance
 of flexibility for both myself and anyone interested in the tools.

 There will likely be multiple donation levels to choose from, so if you
 want email support that would be available at a certain minimum, and other
 incentives for higher amounts, yet still allow a gratis option for those
 who may not yet have income streams the tools contribute to.

 There are risks with any model, and I don't expect any donations from dev
 tools to do as much for my retirement as consumer apps do.  But every
 little bit helps so that's my intention at the moment, unless someone here
 has a better idea for both making more money to keep such efforts viable
 while also making the tools very easily available for anyone who can
 benefit from them.

So the Unix case should be:

 else if is a file /sys/class/power_supply/BAT1/ then

 Thanks for checking, Michael.

 That would make sense, because AFAIK the Pi has no Advanced Configuration

 /proc would accurately reflect a non-discharging battery state (since there
 ain't no battery at all).

 I'll explore further to see if I can find a definitive reference on that,
 but so far it looks like we're on our way.

 For any Linux-using laptop owners here (that means you, Mark Wieder g):
 do you find your charging status in:

  /proc/acpi/battery/BAT1/state

 ...or:

  /proc/acpi/battery/BAT0/state

script, so it's available everywhere in LC:

on controlkeydown which
  if which = space and the shiftkey is down then
 put the long name of the target into targRef
 if field is not in targRef then pass controlkeydown
 if revNewScriptEditor is not in targRef then pass controlkeydown
 put the mouseText into the selection
  else
 pass controlkeydown
  end if
end controlkeydown

Then just set the insertion point in a script and hover over a variable name 
and hit the spacebar (with control + shift) and the variable name is copied 
over for you. Adjust the modifier keys as needed -- in my workflow I use 
control-shift-key for all my scripting shortcuts.

this message. I am very sorry for the annoyance. This is the very first
time in 20 years on the Mac I've had a problem with my machine getting

Re: scrollbars for a stack?

[Peter Brigham]

Here's one solution, no scrollbars but allows scrolling using the
scrollwheel or two-finger touchpad scrolling if available. Put the
following into the card script of your stack (or the stack script if more
than one card):

on rawkeydown what
  put the top of stack myStack into t
  if what = 65308 then -- scroll down
set the top of stack myStack to t-12
-- adjust the parameter as desired
  else if what = 65309 then -- scroll up
set the top of stack myStack to t+12
  else
pass rawkeydown
  end if
end rawkeydown

 Some of the text can be small (remember, I can't change that!), so I have
 coded to use scaleFactor to allow zooming.  On even a 15 screen, this will
 rapidly create a stack taller than the screen.  In other cases, someone
 might simply want to zoom yet use less screenspace.

 Currently, the rendering is done by placing the groups on card 1 of the
 output stack.  It would seem simpler to simply slap scrollbars onto the
 stack, and let the user scroll when desired--but this doesn't seem to be a
 supported feature of livecode, unless I've missed something.

 The cleanest (least dirty?) way I see to achieve this at the moment is to
 create yet another group containing all of my display groups, and resize
 that group each time the window resizes.

 Or is there a better way?

Fwd: Shared Doc

[Peter Brigham]

Ah, found out something about this:

From McAfee:

-

The Google Docs phishing scam is a textbook example: it aims to trick you
into handing over sensitive login details, and it does exceptionally well
http://gizmodo.com/beware-of-this-dangerously-convincing-google-docs-phish-1546278702.
The scam starts with an email referring to an “important document” stored
on Google Docs. Clicking on the link in this message will take you to what
appears to be a Google Docs login page—but it’s not. This fake login page
allows scammers to collect your username and password for their own
malicious use.

Unfortunately for Gmail users, the page in this case is remarkably
convincing—emulating Google’s typical login page. And here’s the clincher:
because this scam is hosted on Google’s servers (the scam is, after all, a
public folder on Google Drive) it effectively sidesteps one of the more
reliable ways to detect a phishing scam. Generally speaking, phishing URLs
are one or two characters different from the official website that they’re
masquerading as. To top things off, because the scammers were hosting this
attack on Google’s servers, the URL appears to be secure.

This attack on Google Doc users is especially troubling as Google uses a
single login across all of their services. If the scammers successfully
obtained login credentials for your Google Docs, they’d also be able to
access your email, Chrome browsing history (including searches), YouTube
account, and perhaps even be able to make purchases through the Google Play
store if you’ve previously registered your payment information.

Despite the sophistication of this scam, there’s light at the end of the
tunnel. After its discovery earlier this week, Google has successfully
removed the phishing pages. They’ve also stated that their “abuse team is
working to prevent this kind of spoofing from happening again.”
-

I have changed my google password.

Re: popUp a button with itself on modified mouseDown?

[Peter Brigham]

I'm late to this discussion but here's what I do. It's a modular solution,
and I use it a lot. It's great for contextual menus for right-clicking in a
field (customize the button contents depending on context) and I've often
used it for just what you are doing, to offer a popup list on
right-clicking a standard button. Once it's set up you will likely find
yourself using it for lots of things, since calling it is as simple as:
   put popChoose(Vera,Chuck,Dave,-,Lovely Rita,Nowhere Man)
into uChoice

function popChoose
   -- create a popup button in your mainstack or a library stack
   --button style = menu, menumode = popup, name = contextualMenu
   --button script:
   --  on menupick what
   -- set the uSelection of me to what
   --  end menupick
   -- make the button invisible when you're done, if needed

   -- then paste this handler into a suitable stack script, so it's
available anywhere
   --could be the same stack the button is in, but that's not necessary
   -- enter the short name of the stack containing the button
   --into the constant declaration below.

   -- popChoose() can accept a cr-delimited list of choices
   --or a comma-delimited list
   -- eg: put Vera  cr  Chuck  cr  Dave into choiceList
   -- put popChoose(choiceList) into userChoice
   -- or: put popChoose(choice1,choice2,choice3) into userChoice
   -- or: put popChoose(One,Two,Three) into userChoice

   constant popChooseStackName = yourLibraryStack

   put the params into tList
   put offset((,tList) into q
   delete char 1 to q of tList
   delete char -1 of tList
   replace comma  space  quote with comma  quote in tList
   replace quote  comma  quote with cr in tList
   if char 1 of tList = quote then delete char 1 of tList
   if char -1 of tList = quote then delete char -1 of tList
   put empty into u
   set the uSelection of btn contextualMenu of stack popChooseStackName
to empty
   put tList into btn contextualMenu of stack popChooseStackName
   popup btn contextualMenu of stack popChooseStackName
   put the uSelection of btn contextualMenu of stack popChooseStackName
into u
   set the uSelection of btn contextualMenu of stack popChooseStackName
to empty
   put empty into btn contextualMenu of stack popChooseStackName
   -- belt and suspenders, don't leave contents hanging around
   select empty
   if u = empty then
  exit to top
  -- ie, mouseRelease, no action
   end if
   return u
end popChoose

Re: How do I remove part of a path?

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

 this:

   set the itemdelimiter to tab
   return item pitem of pstring

 put tabItem(3,myString) into myColumn
 
 Since the itemdelimiter setting is local to a handler, don't need to
 save/reset it.  Saved me a few hundred lines of coding and eliminated
 itemdelimiter debuggung issues.
 
 I wish there was a tab-delimited chunk type native to LC.  I see there is a
 columndelimiter property that is set to tab but I think it's only use is for
 combine and split on arrays.  Would be great to be able to do put column 3

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

 not return to any other image no matter where I move the mouse to.
 
 
 This is the first time I've attempted to control the cursor so no doubt I'm

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.

 I've never been a computer professional. Not even close. I taught myself to 
 write Basic programs for my Atari 64, mostly out of curiosity. Around 1984 I 
 taught myself HyperCard. I wrote a variety of applications for home and 
 business use. A pretty good phonics tutorial for my kids, among others. And I 
 gradually cobbled together a complex set of HyperCard stacks, which I use 
 every day to run my business. They're crude, kludgy and ugly, but they work. 
 Many thousands of lines of script, no idea how many thousands. When I need a 
 new feature, I write it. Often, it's working reliably in less than an hour. 
 It's been years since I saw an error message. Sometimes I discover clever 
 and useful features I wrote and forgot about.
 
 When HyperCard became obsolete, I moved over to Runtime Revolution, which was 
 rather an ordeal, because RR was far more complex. It's comfortable now. And 
 now it's LiveCode, but I've barely noticed the change. LiveCode does many 
 things I don't understand, but that's not a problem.
 
 I still write stacks for my own use. I recently written a stack to help me 
 study and identify photos and songs of birds. Also, I'm taking notes for a 
 book and I've written a stack to help me organize the notes. I will 
 eventually use the same stack to help me develop the book -- probably some 
 kind of a one-paragraph-per-card arrangement with many summarizing, indexing, 
 re-sequencing, search and notation features. I tweak old features and invent 
 new ones as I go along.
 
 None of this seems very difficult. It's a gradual transition from HyperCard. 
 I'm not really a nerd -- computers don't fascinate me all that much. I write 
 a stack when the time invested justifies the functionality of the final 
 product.
 
 It's gradually dawning on me that programmers like me have become rather 
 rare. Fewer and fewer non-professionals on this list, as far as I can tell. I 
 don't understand why, seems like a shame.
 
 Many people have use for the kind of functionality an amateur and dabbler can 
 get out of LiveCode, and it isn't that hard to do.
 
 Admittedly, HyperCard was easier, simply because it was less complex. I've 
 wondered if LiveCode might be more approachable if it had some kind of dumb 
 mode, sort of like the old userLevel system in HyperCard. Probably won't 
 happen though.
 
 FWIW...

Re: Setting a dirty flag for a file

On Jul 21, 2011, at 4:02 PM, Mark Schonewille wrote:

 Hi Charles,
 
 I read your e-mail again. I understand that you want to know whether one or 
 more fields have changed, not whether a file is open.
 
 Usually, I generate an md5Digest and save that:
 
 on closeField
  makeDigest 
 end closeField
 
 on makeDigest
  put empty into myDigest
  repeat with x = 1 to number of fields
put md5Digest(fld x  myDigest) into myDigest
  end repeat
  set the cDigest of this stack to myDigest
 end makeDigest
 
 function dataChanged
  put empty into myDigest
  repeat with x = 1 to number of fields
put md5Digest(fld x  myDigest) into myDigest
  end repeat
  return (the cDigest of this stack is myDigest)
 end dataChanged
 
 You just will have to figure out what is a smart event to check the digest: 
 closing a field, closing a window, opening a window, refreshing the file 
 menu, etc.
 
 When you close the window, you might want to do this:
 
 on closeStackRequest
  if dataChanged then
answer Do you want? with Don't Save or OK or No
if it containt Don't then
  exit closeStackRequest
else if it is No then
  pass closeStackRequest
else
  // do your saving stuff here
  // return true if the file was saved
  if the result is true then
pass closeStackRequest
  end if
end if
  end if
 end closeStackRequest


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
   ... rest of your initialization here ...
   ...
end preopenstack

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.

Re: text formatting

You can create the htmltext by hand as suggested, or you can do something like 
the following (not tested):

-- script snippet
local dvdr =   -- or whatever

-- tEntry contains the template for an entry

replace timestamp with tTime in tEntry
replace firstName with tFirstName in tEntry
replace lastName with tLastName in tEntry
replace message with msgText in tEntry
repeat while cr is char -1 of fld msgList
   delete char -1 of fld msgList
   -- make sure no empty lines in fld
end repeat
if line -1 of fld msgList  dvdr then
   put cr  dvdr after fld msgList
end if
put the number of lines of fld msgList into startLineNbr
put cr  tEntry after fld msgList
set the textFont of line startLineNbr+1 to -1 of fld msgList \
   to empty -- start with no formatting
-- on timestamp
set the textSize of line startLineNbr+1 of fld msgList to 8
set the forecolor of line startLineNbr+1 of fld msgList \
   to gray
-- firstName lastName: wrote:
set the textStyle of word 1 to -2 of line startLineNbr+2 of \
   fld msgList to bold
-- message
set the textSize of line startLineNbr+3 to -1 of fld msgList \

 Hi John
 
 I would look at the HTMLtext property in the Manual/Dictionary.
 
 You would take your text, line by line, and wrap each one with the
 appropriate HTML code
 eg
 put font color=grey size=1dateStamp/fontcr into myMsg
 put font color=black size=2bfirstNamesurName/b/fontcr after
 myMsg
 put font color=bluetheMessage/fontcr after myMsg
 set the HTMLText of fld myField to myMsg
 
 To get the size 16 point text you may have too set the default text size of
 the field to 16 - the HTML should vary it.
 To get the ruled line I think it will be necessary to produce a graphic line
 and use the img src tag to reference it.
 
 
 I haven't tried this so you may have to change the colour references to
 numeric values but this hopefully will put you on the correct track

 The problem is that the message-text varies in length and that there may be

 to set the TextColor and TextSize properties while populating the field and
 that I cannot do this afterwards.
 
 So:
 - How can I set the style of the text, put some text in the field and
 change the style again?
 - how can I put in a horizontal line that separates the messages?

 Maybe I'm misunderstanding the purpose of linkText.  What I want to do is

 All that setting the style of a textrun to link does is to display it as a 
 web link and when it is clicked it sends a linkClicked message to the field 
 with the first parameter being the text that was clicked. It's up to you to 
 trap the linkClicked message and then do something with it.
 
 An alternative method is to set the htmlText of a field to text that includes 
 an a href= tag; if you do *that*, the value in href is returned as the 
 parameter to linkClicked, NOT the text itself. Consider this HTML chunk:
 
  a href=TestThis is a test/a
 
 The phrase This is a test will be underlined and clickable, but when you 
 click it:
 
 on linkClicked pText
  answer pText

 This would answer Test, not This is a test.

 were a way to turn that off.

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

 But since we're stuck with it, one solution is to make your Find field the 
 first one (the lowest layer) if possible. Or, see my suggestion in my other 
 post. Or add an (ugly) command to an openCard handler that sends a message in 
 1 millisecond to another handler, which in turn focuses on nothing (or on 
 your field if you prefer.)
 
 
 With the focus gone, my user will probably try to press Tab to return the
 focus to the input field. But when the focus is on the card, none of my
 buttons receives that Tab keypress.
 
 Put the tabkey handler into the stack or card and check the target to see 
 which object received the message.

Re: System Date/Time Format Problems

[Peter Brigham MD]

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.

 I'm running into some major differences in the way LC displays system date
 and time versus what I have set up in my OSX control panel and wondering if
 anyone else has run into this.  This is in the context of providing my users
 with a preference setting for how they want dates/times displayed.
 
 First problem is that OSX has 4 date and time formats (Short, Medium, Long,
 and Full) whereas LC only has three (Short, Abbrev, Long) so there are some
 inevitable discrepancies.
 
 For dates:
 LC Short = OSX Short
 LC Long = OSX Full
 LC Abbrev = no OSX format
 no LC format = OSX medium or long
 
 
 For times:
 LC Short = OSX Short
 LC Abbrev = OSX Short
 LC Long = OSX Medium
 no LC format = OSX Long or full
 
 Any thoughts?

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: How to structure HTML text (tags and attributes) for processing in LiveCode?

 I am a LiveCode novice (1 year, so still a Rookie!). So, part of the

 If you have a URL, I could give some concrete examples of good steps to 
 consider.
 The reality is that there are different ways that become easier depending on 
 the structure of the html.
 
 If the page is a catalog or inventory page, there are lots of repeating 
 blocks of code.  If it is a set of tables, nested tables, or other cellular 
 structure, then the approach should be different.
 
 If it is mostly text blocks in p div without links, or with a tags, 
 again can change the structure of your repeat loops.
 
 One approach is to keep replacing the html strings with delimiters, such as 
 tab, cr, ~, or a run of chars such as  and then pase the resulting text 
 block.  There are almost too many ways to do this.  The key is to those that 
 fit together, rather than try to mix and match combinations of all of them.
 
 This is usually a very confusing puzzle, since html offers so many variations 
 and exceptions.
 
 Hope this helps rather than add to the confusion.

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 td valign=top align=center 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 p with lineChar in tText
   replace /font/tdtd valign=topfont face=Arial size=-1 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.

Is there some reason you use focus on me as opposed to select text of me ?

Re: CustomProperties

 You can. You can even set a custom property to an entire stack.
 
 
 I use these all the time, they are incredibly powerful and convenient.
 
 
 But I do not understand what it means to set a property to an object, as 
 opposed to a chunk of text (or maybe a video file?). So you can set the xxx 
 of btn b1 to btn b2. And if you then get the xxx of btn b1, you will 
 get empty, unless you have made button b2 into a container, and put some 
 text into it. In that case you get that text back. But that is not the same 
 thing as having the button itself as the contents of the property, is it?
 
 
 It is a disconnect between what I think of as a property, and what I think of 
 as a container.
 
 
 Can't wait to see how this works; I have always wondered...

 You may find the copy command will do what you need quite handily, since it

 copy obj to dest
 
  e.g.:
 
 copy grp 1 of stack TemplateParts to this cd of stack UserStack
 
 When using the to option with the copy command it doesn't affect the

 Hi Richard
 
 I tried your suggestion with
 
 copy grp mygroup of this stack to the umycustomProp
 
 and got a Script Compile error
 Error description: Function: missing '('
 
 So I guess that controls can't be stored there.
 
 Correct. As I'd written, I know of no way to 
 store controls in custom properties.
 
The copy command can be used by simply storing your groups in some other 
stack as a repository, copying them into the user's stack as needed.



If you don't want to use a storage stack, which is really the easiest thing to 
do, you can approximate storing a control as a customprop with something like 
this:

put the properties of btn myBtn into btnProps
-- btnProps is an array of properties
set the storedBtn of stack myStack to btnProps

The, to reconstitute the control (I think of this as adding water to a 
freeze-dried stew and sticking in in the microwave...),

put the storedBtn of stack myStack into btnProps
create invisible button
set the properties of it to btnProps

(will also make the new button visible if the original was visible)

FORMalizer -- form printing utility

[Peter Brigham MD]

As I just used this utility stack of mine again recently and was reminded of 
how much it streamlines a particular task, I thought I'd make it available to 
anyone who would like to use it.

In this age of electronic everything, there are still situations when you have 
to fill out a paper form for some reason. If you have to do this repeatedly it 
gets onerous, and it's particularly annoying if you are just rewriting 
information you have in a stack. FORMalizer allows you to print out a form with 
fields automagically filled in with data from a Rev stack. I use it because I 
have to print out and fax stuff to insurance companies, etc. I used to have to 
fill in all the fields by hand -- now I click a button and the form pops up 
with all the fields filled in for me, and I print it and send it out.

FORMalizer automates creating a built-in form as a substack of your mainstack. 
How it works: Open your data stack, then open the FORMalizer palette, then 
click a button to import a PNG or JPG of the form you need. (Multiple page 
forms are supported.) Adjust the rect of the image(s) if necessary. Next, click 
a button on the palette to create a field overlaying the form, name the field, 
move it to the correct position on the form, resize it if required, and repeat 
until all the fields you need are created. You can set the font and fontsize 
for the fields as desired. FORMalizer also makes it easy to create checkboxes 
(actually small locked square fields) and even groups of checkboxes that behave 
like radiobuttons (clicking one member of the group checks that button and 
unchecks the others in the group).

Then, click the clone and attach... button on the palette to clone the form 
stack and attach it as a substack of your data stack. Finally, click a button 
to put a pre-made script snippet on the clipboard, and paste the snippet into 
your data stack script (or wherever is appropriate in your message path). You 
can then edit the script, which will look something like this:

on emailReleasePrint
   set the label of btn FMprint of stack emailRelease to print
   put empty into fld id 1960 of card 1 of stack emailRelease -- clinName
   put empty into fld id 1961 of card 1 of stack emailRelease -- clinEmail
   put empty into fld id 1963 of card 1 of stack emailRelease -- anc1name
   put empty into fld id 1964 of card 1 of stack emailRelease -- anc1relp
   put empty into fld id 1965 of card 1 of stack emailRelease -- anc1phone
   put empty into fld id 1966 of card 1 of stack emailRelease -- anc1email
   put empty into fld id 1967 of card 1 of stack emailRelease -- anc2name
   etc.
   put show into tMode
   send printForm  quote  tMode  quote to stack emailRelease
end emailReleasePrint

Replace those emptys with anything you like -- fld clinName, 
firstLast(ptName, true), item 3 of fld ancillary -- and when you call the 
handler the fields will be filled appropriately and the form will appear for 
review (and for filling in other fields by hand if you need to) and for 
printing.

This is a specialized need, to be sure, but if you have the need, here is a 
solution that will save you time and aggravation.

 Then in my hidden test popup menu, I have numbers 1 through 35. This works 
 until I type in a number that causes the popup menu to hit the top of the 
 screen. Unlike an option menu, it does not truncate itself with a scroll 
 arrow - it just stops at the top of the screen with the first menu item at 
 the top. Interesting, it will truncate with a scroll arrow if it hits the 
 bottom of the screen.
 
 Any thoughts or suggestions?

The formattedrect function will give you the location (relative to the window) 
of a chunk of text. Don't know if that would help.

Re: Data-Entry in a LiveCode form using the tab key

[Peter Brigham MD]

Solved one part of the problem -- there has to be a wait with messages after 
the mouseclick. Without this the mousecontrol always returns empty. I have no 
idea why.

I haven't yet figured out how to change the cursor to ensure the user knows 
s/he is still in the doFieldOrder mode -- it doesn't stick after the first 
click. If you will be actually using this technique then I can investigate 
further to find a fix for that.

The following works except for the cursor problem. Right clicking ensures that 
the mouseclick is sent even with unlocked fields.

on doFieldOrder
   answer RIght-click on the fields in the order you want. \
  When done, press the commandkey. as sheet
   repeat
  set the defaultcursor to hand
  -- why does this only work the first time??
  wait until (the mouseclick or the commandkey is down)
  if the commandkey is down then exit repeat
  wait 1 tick with messages
  put word 2 of the mousecontrol into mc
  put the long id of control mc into fID
  if not (fID begins with field) then -- not a field
 answer You must click on a field!
 set the defaultcursor to hand -- try again
 next repeat
  end if
  select the text of fID -- user feedback
  wait 5
  select empty
  put word 3 of fID  cr after fldList -- short id
  set the defaultcursor to hand -- try again
   end repeat
   delete char -1 of fldList
   put fldList
   --  set the tabOrderList of this card to fldList
   set the defaultcursor to empty
   beep -- user feedback
end doFieldOrder

 WHOOPS! Should be: 
 if the commandkey is down then exit REPEAT
 
 But theFieldList still returns empty, even after I put this into a mouseUp 
 handler. Also, I noticed that the selection did not change. Apparently, 
 mouseUp messages are not getting sent to the object I am clicking on because 
 I am within a mouseUp message already I guess?? Doesn't sound right though.

 Or you can get a list of fields whose focusable is true and locktext is false

 The advantage to this approach is that it will work universally for any card. 
 Ideally you would want to copy every editable field on the card to a new one, 
 along with a Cancel and Save button, and then save the list of fields in a 
 property of the original card. 

You wouldn't have to make a whole new card, just a menuitem which launches 
something like (not tested):

on doFieldOrder
   answer Click on the fields in the order you want. When done, press the 
commandkey.
   repeat
  if the commandkey is down then exit repeat
  wait until the mouseclick
  put word 2 of the clickfield into cf -- fld nbr
  if cf = empty then -- not a field
 answer You must click on a field!
 next repeat
  end if
  select the text of fld cf -- user feedback
  wait 5
  select empty
  put the short id of fld cf  cr after fldList
   end repeat
   delete char -1 of fldList
   set the tabOrderList of this card to fldList
   beep -- user feelback

then use the customprop to find the id of the next field in the list when the 
user tabs out of the field.

Re: Currently playing song on iPod Touch

[Peter Brigham MD]

Tom McGrath put together an iTunesLibrary in LC. I can't seem to find  
it in my LC files, but I'm sure he would make it available to you. I  
used his library to make a little thing called iTunesWidget. Pop it  
into your plugins folder, and any time you're running in the IDE, you  
can open it up and use it to control iTunes without leaving LC. It's a  
little 32-pixel round customwindowshape stack that can be set as a  
systemwindow if you want, uses AppleScript to manage iTunes' basic  
functions. Very simple: click to start/pause iTunes, cmd-click to go  
to iTunes, opt-drag to move widget, ctrl-click or right-click for  
option menu. Hovering over the widget displays the current track,  
album, and artist in a tooltip. You can get it at:


http://home.comcast.net/~pmbrig/iTunesWidget.rev.zip

I haven't tried to pass this around much, because for reasons I can't  
track down, clicks sometimes disappear into emptiness with no  
response, sometimes mousemove doesn't trigger the tooltip display,  
etc. Something is swallowing system messages, or maybe the AppleScript  
messages are going awry, anyway it's occasionally a bit unpredictable.  
But I use it when I'm working in the IDE and want to listen to some  
MP3s. Handy because I don't have to change gears when the phone rings,  
just click to pause, and answer the call.


If you can't find Tom's library stack, look at the stack script in the  
widget for ideas on what you're trying to do. Tom did the real work  
for this, I really just adapted his scripts.

Re: novice question re marked and customkeys

I suspect that using a customproperty of the card would be faster for  
large numbers of cards. Accessing the contents of a field is slow,  
relative to pulling customprops. But it probably doesn't matter unless  
you have 1000 cards.

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

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?

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.

Re: newbie script question re Find command

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 tFld contains tStr

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 tFld 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 tFld of (item 3 of foundList)


to get the chunks.

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

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.

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 stackName then the stack stackName 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 stackName to \
   the short name of card 1 of stack stackName

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 myStack

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 stackPath


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 stackPath


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?

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.

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
  doAlert
  exit to top
   end if
   delete item i of dList

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

With this in place, if you just use:

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

If you're talking about a system to prepare ebooks for publishing in  
various formats, I would be optimistic about LC's ability to manage  
text processing -- that is one of its strengths. The question is  
getting at the APIs for the ebook formats, unless you just want to  
prepare plain text in a decent format to be uploaded as is. Others  
will know more about the technical end of the various formats, but as  
far as text and string manipulation goes, LC is very flexible and fast.

Re: Getting Contents of Multiple fields in order (Left-to-RightDown)

Thanks for looking into this with me!  The way you (Jim) appear to  
take what I did and turn it around in a fraction of the lines is  
amazing! Someday I want to be able to do that :-)


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?

Chipp’s AltLayerTools does it for me!


Is this still available? I can't find it on the Altuit website.

Re: When is a Word not a Word?

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

put wordoffset(field Selection,myLine) into mywordoffset

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.


Best regards,

Mark Schonewille

Now, the other mystery -- I convert my stack to a standalone (now

Anyone have any ideas what could cause this behavior? Per my

scripting, as it seems that the quit command is handled by the  
system. So what could be the problem?

Re: (mac) application menu

This was driving me crazy too. After messing around with it, I pieced
the following together and it's worked for me (I am using Rev 2.6.1):

on appleEvent pClass,pID,pSender  --I got this from Ken Ray's web site
  switch (pClass  pID)
  case aevtquit
answer Save changes? with Don't Save or Save
if it is Save then
  doSaveStuff
  pass appleEvent
else pass appleEvent
break
  default
pass appleEvent
break
  end switch
end appleEvent

on closeStackrequest
  Global homeStack
  if the short name of this stack is homeStack then
answer Save changes? with Don't Save or Save
if it is Save then
  doSaveStuff
end if
  end if
  pass closeStackrequest
end closeStackrequest

on shutdownRequest --I only use this for Windows
  Global homeStack
  if the platform contains Win then
if the short name of this stack is homeStack then
  answer Save changes? with Don't Save or Save
  if it is Save then
doSaveStuff
  end if
end if
  end if
  pass shutdownRequest
end shutdownRequest

Re: RevOnline: New version of Shell Command Help

[Peter Brigham MD]

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  
parse it?

I encountered this as I was trying to read the man for ls on the  
server

machine [On-Rev]... the text file I obtained was almost unreadable!

Nonetheless, doubled chars are interpreted as *bold* chars on geek
apps (you know, line command) ;-)

Interesting. This trick is documented in the man page for man at the  
bottom, though nowhere in the syntax list does it list the col or - 
b parameters.


To  get a plain text version of a man page, without backspaces and  
underscores, try

 # man foo | col -b  foo.mantxt

That was just my reaction to the stack -- great if you know what  
you're
doing already, but you have to know shell commands. (I dropped it  
into my

Plugins folder anyway)

Is there a shell command to get all the shell commands on the  
currently
running system? If so, it should be a snap to expand the stack  
accordingly.

As you can see, the section titles and commands consist of doubled

something to do with the text encoding? Pardon my ignorance, I'm a
