Re: Identifying IDE stacks

[J. Landman Gay via use-livecode]

This has been informative. IDEUserMainStacks() is exactly what I want, I 
don't care about substacks at the moment.


With four or five different ways to get the info, I think all bases are 
covered. Many thanks to those who have the courage to dig through the 
IDE scripts.

Re: Identifying IDE stacks

Interesting...so there are two ways. It looks like revIDEStackIsIDEStack 
needs a long id, and revStackNameIsIDEStack needs only the short name 
but will also accept a long ID.


Thanks for finding the list of qualifications.

If you're just looking at the open stacks, you can iterate through them 
using


revStackNameIsIDEStack(tStackName)

which will return true if it's a system stack.

According to the comments for revIDEStackNameIsIDEStack which call it,

A stack is considered part of the IDE if any of the following are 
satisfied:

* Its name begins with "rev"
* It was loaded by the initialisation library
* Its name begins with "com.livecode."
* Its name is "message box, answer dialog, ask dialog, or home"
* Its _ideoverride property is true

 Thanks Richard. I went ahead earlier and implemented the detailed files 
method and then filtered by filename & *. Works great. I have functions that 
takes the last modified seconds and converts it to an SQL datetime format. Now 
I can look at the filename (no matter what the path to the file appears to be 
to the end user's app) along with the last mod datetime. If those two are 
identical it is the same file, albeit possibly another copy, which doesn't 
matter to me. 

I'm attempting to build into my app a files system with versioning and custom 
user/group permissions in anticipation of a workflow based interface. That will 
take the Forms Generator to a whole new level! Wheee!

Folks:
I can’t seem to get an external script only stack to get assigned to the 
“Stacks” list for an iOS app in LC 9.0.0. Thus, it appears to me that all 
stacks must be substacks in iOS. Is this true?

Shell is great for things we can't do in LiveCode Script yet may not 
warrant writing special C-based API interfaces for in LC Builder.


But in addition to the complexity of attempting to rely on such 
interprocess communication across platforms, it also carries a certain 
impact on memory and performance.


"Why run one process when you can run two at twice the price!" :)

In the enhancement request I cited earlier:
https://quality.livecode.com/show_bug.cgi?id=20384

...Trevor raised a good point about instances where apparently macOS 
sometimes disallows access to a folder even while allowing access to 
specific files within it.  It's hard for me to see how that would not be 
a configuration error on any other system, but I trust Apple has a good 
reason for that.  And in such cases, we're hosed with any current LC 
Script solution that needs access to the whole folder's content.


But for the other 99.9% of cases, using a scripted handler reduces the 
task to a one-liner, here made even more convenient by allowing either 
the detailed info returned in its LC-native comma-delimited format or as 
an array if preferred:



on mouseUp
   put specialFolderPath("desktop")&"/test/Thisisafilename1000" into tPath
   put fwFileInfo( tPath, "Array") into tA
   if the result is not empty then
  answer the result
   else
  put the keys of tA
   end if
end mouseUp


function fwFileInfo pFile, pArrayFlag
   -- Returns info for the file specified in pFile.
   -- By default, returns the data in comma-delimited
   -- form in the order specified by "detailed files".
   -- With any value in the optional pArrayFlag arg
   -- it will return an array with descriptive keys.
   --
   if there is not a file pFile then
  return "No such file: "& pFile for error
   end if
   set the itemdel to "/"
   put urlEncode(last item of pFile) into tFileName
   put item 1 to -2 of pFile into tPath
   put files(tPath, "detailed") into tFiles
   if the result is not empty then
  return "Error getting file info: "& the result & \
" ("()&")" for error
   end if
   put lineoffset(cr& tFileName&",", cr) into tLineNum
   put line tLineNum of tFiles into tInfo
   if pArrayFlag is empty then
  return tInfo for value
   else
  set the itemdel to ","
  put 0 into i
  put 
"name,size,resourceSize,dateCreated,dataModified,dateAccessed,"& \

"dateBackedUp,owner,group,permissions,MacType" into tFields
  repeat for each item tItem in tInfo
 add 1 to i
 if i = 1 then put urlDecode(tItem) into tItem
 put tItem into tA[item i of tFields]
  end repeat
  return tA for value
   end if
end fwFileInfo


Performance isn't bad (times shown in ms on Ubuntu 14.04 with Ext4 file 
system) - each test was done with the slower form of the function call 
that uses the array option:


Folder with 20 files: 0.72
Folder with 5,000 files:  0.024766
Folder with 10,000 files: 0.042299

I'll leave it as an exercise for the reader to compare with benchmarks 
for obtaining the same info via shell.  But at a fraction of a 
millisecond with LC Script even in an insanely large directory, I'll 
wager the time to write the test would exceed any time saved over one's 
lifetime. :)

Unless disabling a group prevented you from interacting with any of the 
children without actually disabling the children. One scenario you have to 
disable all the children, the other you have to re-enable them based upon a 
prior state saved in some fashion. As I said, darned if you do, darned if you 
don't. One leg is both the same. :-)

But it's okay, I can script around it. I'm more interested in a detailed single 
file function, but again I can work around that too. I will just filter the 
detailed files of the enclosing folder and hope that in the distant future 
someone doesn't try to use this function on a folder with 10,000+ files. Of

Re: Detailed File Information for One File

[Bob Sneidar via use-livecode]

Not to beat a severely wounded horse, but one reason for implementing a 
detailed file function (and probably why it hasn't been tackled) is that 
getting the detailed file information from a command shell is decidedly  NOT 
straightforward. *NIX has an ls function, and also has a date function. The 
date function cannot it seems accept spaces in the name, but will accept 
relative paths like ~/Desktop/test.xlsx. ls -r will only give you the year if 
the date is beyond 6 months from present. Date accepts a path in quotes or not, 
but if there is a space in the path you must enclose in quotes. ls decidedly 
CANNOT have a quoted path. 

Windows gets dicier. Typically you would use WMIC and build a query, but I 
think it only works with local files, and not network shares (Parallels uses 
network paths for Mac FolderSharing). It uses back slashes, and these have to 
be escaped as in \\. 

There are a number of other gotchas for each platform, but the upshot is that 
it's a beatch trying to piece together shell commands that work reliably in all 
use cases for every platform. I am sure that after a half a day and struggling 
through all the exceptions for each platform I could piece together a way to do 
it, but it's a real pig I can tell you.

Re: Enable/disable Group enables/disables all children

[Mark Waddingham via use-livecode]

Darned if you do, darned if you don't. I get it. Still, looking at

describes. :-)


You can't tell what the state of disabled was of a child before the 
owning group's disabled property is set - that's the problem.


Imagine we change this without any regard for backwards compatibility to 
the preferred (correct!) model. Then when you open your stack, setting 
the 'disabled' of a group to 'false' will then *only* affect the 
disabled property of the group - not the children. All the children will 
remain with disabled 'true' (as it won't be setting the property any 
more on children).


This means that everyone would have to go through every card of every 
single stack which has groups which are disabled, which contain children 
which should be enabled/disabled with the group's enablement and change 
those child controls disabled property to false (as they will be true at 
present).


I get the feeling that a lot of people have a lot of stacks where the 
group enablement behavior is fine (as they do want their child controls 
to enable/disable with the group), and so they won't have scripted 
anything, so they will find a lot of disabled controls!


Warmest Regards,

Mark.

P.S. The engine change (from memory) is relatively straight-forward I 
think - we already have visible as a pattern - so the main issue is 
migration forward - which could be a lot of work for large stacks which 
might have a mixture of scripted and 'by-engine' enablement/disablement.

RE: Enable/disable Group enables/disables all children

[Ralph DiMola via use-livecode]

I ran into this on a card basis. I have a handler that loops thru all controls 
and disables(and dims) them so a user can't do anything until some function is 
complete and a complementary handler that enables them all. This became a 
problem if one of the controls on the card was disabled. To solve this I put a 
custom property on the card with all the long IDs of all the controls and their 
initial "enabled" state before disabling everything. When re-enabling all the 
controls I look at the array and decide which controls need to be enabled. The 
same thing could be done for groups.

Re: Enable/disable Group enables/disables all children

[Bob Sneidar via use-livecode]

Darned if you do, darned if you don't. I get it. Still, looking at your 
example, it begs the question, what was the state of the enabled property for 
the individual objects before the parent group was disabled? The current 
situation is exactly what your objection describes. :-)

I worked around it by resending selectionChanged to the datagrid that these 
controls reflect, which sets the controls enabled property according to certain 
conditions.

Re: Q on Accessing multi-dimension arrays.

[Bob Sneidar via use-livecode]

Fettling! I'm going to start using that! 

fet·tle
ˈfedl/
verb
gerund or present participle: fettling
• trim or clean the rough edges of (a metal casting or a piece of 
pottery) before firing.

Apparently appropriate as well. Pronounced like feddle, likely where we get our 
fiddle with. And I always thought it was a reference to playing a violin-like 
musical instrument!

I do not believe this has been implemented yet:

That said, wasteful as "the detailed files" is it's probably more
efficient in most cases than the overhead of initing a shell session.
I've had good performance even in directories with tens of thousands of

I think you will have to perform several operations here:

1. convert Hex number to Binary number.

2. find Complement of Binary number.

3. convert Complement to Decimal number.

Your "main problem" is that YOU have to work out the algorhythm to

get the complement as LiveCode does not have that built-in to its system.

Two's complement is a mathematical operation on binary numbers, best known for

The two's complement of an N-bit number is defined as its complement with 
respect to 2N. For instance, for the three-bit number 010, the two's complement 
is 110, because 010 + 110 = 1000.

I think you will have to perform several operations here:

1. convert Hex number to Binary number.

2. find Complement of Binary number.

3. convert Complement to Decimal number.

Your "main problem" is that YOU have to work out the algorhythm to

get the complement as LiveCode does not have that built-in to its system.

Re: Hex to Decimal 2s Complement

[Camm via use-livecode]

Two's complement is a mathematical operation on binary numbers, best known for 
its role in computing as a method of signed number representation. For this 
reason, it is the most important example of a radix complement.

The two's complement of an N-bit number is defined as its complement with 
respect to 2N. For instance, for the three-bit number 010, the two's complement 
is 110, because 010 + 110 = 1000.

Re: Splitting long elements into two lines in an Option Menu

[Richmond via use-livecode]

I've just set up a stack containing 2 fields; one called "fff" 
containing your


original string, another called "fCHOPPED" that is a scrolling list field.

I have a button containing this script:

on mouseUp
   put fld "fff" into FFF
   set the itemDelimiter to ","
   put 1 into KOUNT
   repeat until item KOUNT of FFF is empty
  put item KOUNT of FFF into line KOUNT of fld "fCHOPPED"
  add 1 to KOUNT
   end repeat
end mouseUp

which puts the string into the scrolling list field like this:

/Dialyse rénale
 insuffisance rénale
 maladie rénaleDID
 diabète de type 1//
//diabète insulino dépendant/

This should be 'logical or' - i.e. a control is disabled if any one of 
its parent controls is. It is 'logical and' for the enabled property 
(which is just the 'not' of disabled, of course).

Re: Enable/disable Group enables/disables all children

[Mark Waddingham via use-livecode]

On 2018-04-26 19:06, Bob Sneidar via use-livecode wrote:

Hi all.

I have a group that contains a number of objects, buttons, menus,
fuelds and groups. I just noticed that if I disable a group (so that
none of the objects in the group can be interacted with) I get the
desired effect. However when re-enabling the group, it *ALSO*
re-enables ALL the objects in that group, no matter what their status
was prior to disabling the group.

Is that the expected behavior? If not I will file a bug report. If so,
I will have to find another way to disable all the objects in a group,
or else trap for the action, and save the enabled property for every
containing object so I can reset them.


It has been like that forever - there is an anomaly for it: 
https://quality.livecode.com/show_bug.cgi?id=14881


The 'disabled' property should be effectively computed as the logical 
and of all the parent's property values (kind of like inherited 
properties, but with a different operation merging parent and child 
values), a bit like visible is - why it was never done that way 
originally is a question to which I do not have an answer!


The problem with 'just' fixing it is that it is not possible to 
determine with the current behavior what the 'disabled' setting of any 
control is meant to be. If it is changed, then all controls in disabled 
groups which exist now will remain disabled - everyone would have to go 
through all their stacks and set the enablement of children 
appropriately.


Warmest Regards,

Mark.
