Re: On the dangers of automated refactoring

[Peter W A Wood via use-livecode]

Thanks Andre

I enjoyed putting the library together though at the time unit testing and 
LiveCode just don’t go together. Personally I find developing with tests gives 
me peace of mind about my code. 

As for refactoring, normally defined as the process of improving code without 
changing it’s behaviour, having a set of tests make it so much more productive.

LiveCode provides a really great platform for unit testing. The language makes 
it so much more simple to write unit tests of GUIs than any other language that 
I know. Even my small testing library could drive a GUI script.

I don’t spend much time with LiveCode these days. I always wanted to explore 
the multimedia capabilities of LiveCode which seem to surfing off into the 
ether. I never really put the time into getting on top of the multimedia 
aspects of LiveCode and, in all probability, lack the creativity to build 
anything of note.

PS Red Lang is going slowly. I haven’t been involved for a while. It’s mainly 
legacy Rebol, JavaScript, a little Lua and more JavaScript work for me these 
days.

Your solution seems to be missing a few hundred thousand digits ;-) The 
JavaScript solution prints the first 1,000,000 digits of Pi.

Actually, the article says that the script only can produce 1,000,000 digits 
when run in a Chrome console. It will only print the first 315,633 digits in 
Firefox. (I haven’t tried that to confirm it.)

“Let” was introduced into JavaScript some time ago. It provides block-level 
scope. This console session may demonstrate the difference:
>>> j = 0;
0
>>> for (var j = 0; j < 10; j++) {};
>>> print(j);
10

>>> k = 0;
0
>>> for (let k = 0; k < 10; k++) {};
>>> print(k);
0

Big Integer support was recently introduced into JavaScript. The ’n’ suffix 
denotes a Big Integer, “primitive” numbers are always floats in JavaScript.

[OT] Working with Android devices

[Peter W A Wood via use-livecode]

I have recently got an Android tablet and am seeking advice on how best to work 
with it in general, not so much with Livecode yet. My main machine is a Mac. I 
would like to be able to easily swap files with the Android tablet via wifi and 
to remotely login to it from the Mac. I am hoping that I can do so over the 
local wifi rather than having to connect the Android tablet via USB.

I have a couple of Raspberry Pis on which I installed netatalk so that I can 
access their file systems in macOS Finder. It makes swapping data between the 
Mac and the Raspberry Pi a simple matter of drag and drop. Does anybody know if 
it is possible to install netatalk on an Android device?

I usually use SSH to run programs on the Raspberry Pi. I see that there is an 
app called SSHDroid. Has anybody used it or something similar? 

When I want to access the Raspberry Pi desktop, I connect to the VNC server 
running on the Raspberry Pi. Is anybody connecting to their Android "tablet 
top” from a Mac? How do yo do it?

Sorry about going off topic.

Re [OT] Snakey Problem

[Peter W A Wood via use-livecode]

Richmond

I am no Python expert having only got over Pythonaphobia, which I contracted 
last century, in the last few months.

The standard Python library, which is included in the distribution, includes 
the TKinter GUI library. When Python starts up, it doesn’t load many of the 
standard libraries automatically. That’s why you need the imports before you 
use them. (It imports them from the standard library).

Here is the smallest hello Richmond program that I could find:

import tkinter as tk

gui = tk.Tk()
w = tk.Label(gui, text="Hello, Richmond!")
w.pack()
w.mainloop()

 
It should run in any standard Python3 distribution.

You might want to think about using the new Mu Editor which is aimed at 
beginners. It includes it’s own version of Python3 (3.6 in the current 
release). It’s website is https://codewith.mu  There’s an 
introduction to it at https://www.raspberrypi.org/blog/mu-python-ide/ 


Hope this helps

You can easily run CouchDB on a laptop or PC. There is a little more admin that 
SQLite but not very much. One of the strengths of CouchDB is it’s database 
synchronisation (one-way or both-ways) - 
http://docs.couchdb.org/en/2.1.0/replication/index.html 
.

There is also a mobile embedded Couchbase that should sync with CouchDB - 
https://developer.couchbase.com/mobile  
- I guess that would need a LiveCode Builder wrapper before it could be 
accessed from LiveCode.

Some Unicode characters, such as emojis, have to be represented by two 
codepoints in UTF-16 (known as surrogates) so they take four bytes not two. 
Additionally, the number of bytes for characters with accents will take either 
one codepoint or two depending on whether they have been coded in pre-composed 
or decomposed form. (e.g. ç can be either U+0063 U+0327 (decomposed) or U+00E7 
(precomposed).

So it is isn’t easy to estimate the number of bytes in a UTF-16 string.

I would guess that LiveCode will store the characters of a string in single 
bytes if all the letters of the string conform to ISO-8859-1. So if you can be 
certain that your text is all ISO-8859-1 encoded, you can estimate at 1 byte 
per character. (The guess is base on the fact that the first 256 Unicode code 
points replicate ISO-8859-1).

Re: Kognition Beta Test - call for volunteers

[Peter W A Wood via use-livecode]

Dear Kevin 

First, congratulations on reaching Beta stage of Kognition. Your description on 
if it is very intriguing.

I think I can offer you an interesting beta test environment. At the moment, I 
have three primary projects (and a number of smaller ones), the data for each 
is stored in diverse forms but, in most cases, very common forms. I think this 
would provide a good test of Kognition’s reach.

Here are the main data sources for each project:

Project 1
Atlassian JIRA - Cloud System - issue and task data
Atlassian HipChat - Cloud System with local client - project 
discussions including requests for action
Atlassian Confluence - Cloud System - project documents
Google Calendar  - Cloud System - project meeting schedule
Google Mail - Cloud System - project email and notifications 
(no local copies)
Project Artefacts - Local Files - documents (markup, pdf), 
code, binary data

Project 2
Google Docs - Cloud System - documents, spreadsheets, 
presentations
AltME Messaging System - Local Files - documents (text, markup, 
pdf), to-do lists, contact list, chat
Project Artefacts - Local Files -  documents (markup, pdf), 
code, binary data
Email (Apple Mail.app) - Local Files - messages + attachments

Project 3
Gitter - Cloud System - project discussion with actionable items
Github - Cloud System - project issues, documentation (markup)
GitBook - Cloud System - published documentation
Trello - Cloud System - project tasks
Blogger - Cloud System - website source and management, user 
comment management
Website - Cloud - project website
Google Groups - Cloud System - membership data, messages
Google Mail - Cloud System - project email

I believe that would provide a good test of Kognition’s data acquisition 
capabilities though the relationships between the data will be relatively 
simple.

I have a MacBook Pro(Retina, 15-inch, Mid 2014), it has a 2.5 Ghz Intel Core 
i7. 

Best regards

Peter

It might be the Apache is being fussy about the lack of a trailing “/“ in the 
Script Alias or giving the name of an executable when a directory is required.

These are the relevant parts of the config I use happily with Apache 2.4:
 
ScriptAlias /livecode-cgi/ "/Users/peter/Sites/LiveCodeServer/“


AllowOverride None
Options +ExecCGI
Require all granted


AddHandler lcscript .lc
Action lcscript /livecode-cgi/livecode-server

Hope this helps.

People’s opinion of what is needed for TDD differs widely. The so called xUnit 
testing frameworks are generally quite basic (test specification, assertions 
and test runners) but suffice for many people. They typically cannot be easily 
used to test GUI code. Other testing frameworks, it seems especially in the 
JavaScript world, extend much farther with test doubles, code coverage, and 
testing user interfaces via the browser.

I have published a simple test framework, Mini-Test. It can be used to test 
both LiveCode handlers and GUI interfaces. (This is latter is a credit to 
LiveCode’s features not me). It is rooted in MiniTest, the testing framework 
included with Ruby. It does not include test doubles, code coverage or 
performance testing.

LiveCode, the company, has a test framework but, personally, I found it too 
complicated for my own use. I felt something written wholly in LiveCode would 
be easier to handle.

I feel that the LiveCode engine makes it extremely easy to write a test 
framework that will do all of the above. It just needs a little thought, such 
as designing a set of commands to automate user input simulation, and a little 
work.

You can open them and read the scripts in BBEdit under OS X. I would imagine 
that the free version, TextWrangler, would be able to do the same.

I was also able to open them in Gedit on Ubuntu but Gedit complained about some 
of the “binary” data not being correctly encoded UTF-8. Again I could see the

Having to type titles of buttons and text of labels and fields of GUI objects 
into a contents property in a separate window is this issue to me. I find it 
counter intuitive. Every time I use the IDE, I have to remember to open the

I think that you have missed out one way to contribute that would be very 
valuable to both the community and LiveCode. That is writing automatically 
runnable tests. There is an automated test suite but it is kept under lock and 
key by LiveCode so that community members cannot contribute by submitting 
meaningful tests.

I built my own simple testing framework 
(https://github.com/PeterWAWood/LiveCode-MiniTest 
) and have a handful of tests 
(https://github.com/PeterWAWood/LiveCode-Tests 
). (If you run 
the tests, you will see that some of them fail.).

A set of community developed automated tests would be a great resource that 
could be grown over time.

[ANN} LiveCode List Processor - Version 1

[Peter W A Wood]

I have found time to complete version 1 of my LiveCode List Processor. You can 
find it at https://github.com/PeterWAWood/LiveCode-ListProcessor

Many of you may be wondering why I bothered to write it when LiveCode’s 
built-in list processing (of delimited strings) is very good. The main reason 
is that LiveCode’s lists lack a memory. You can’t process a couple of items at 
the top of a list, go and do some thing else and then start processing the 
third item in the list. Well not easily. The List Processor does have a memory 
and you can move forwards and backwards along a list. The current position is 
even remembered when the list is saved.

A simple example of its use would be if you wanted to use some colours in turn. 
First you would make a list:

put LP.makeList(“red:green:blue:pink:purple:brown:black:”, “:”) into 
myColours

When you wanted to get the next colour, you would simply get the next item in 
the list:

put LP.next(myColours) into nextColour  #nextColour would be set to 
“green"

You can get the next colour

put LP.next(myColours) into nextColour  #nextColour would be set to 
“blue"

You can save the list

put LP.save(myColours, myURL) into tTemp 
# tTemp 
would be a binary copy of the list

You can load the list from the URL and get the next colour

put LP.load(myURL) into myColours
put LP.next(myColours) into nextColour  #nextColour would be set to 
“pink”

I suspect the number of uses of these lists with a memory is quite wide. I plan 
to use it to store data that I previously held in a set of cards. You can 
navigate through the list in a similar way to how you would navigate through 
cards. One small difference is that the lists don’t automatically cycle around 
from the last to first items as LiveCode cards do. (It would be easy to add 
that to the List Processor though).

When I was developing the List Processor, I wrote the tests using LiveCode 
MiniTest -https://github.com/PeterWAWood/LiveCode-MiniTest

The is some simple documentation on the Github page.

When writing the List Processor, I concentrated on getting it working correctly 
rather than speed. I’m sure that big improvements could be made and I would 
welcome comments and suggestions.

Regards

Peter

Thanks for the confirmation as I wasn’t sure that was the case for all arrays 
due to the existence of the extents function.

It is not possible in this case as the order of the elements is significant. I 
use a different function to remove the last element of the array.

Delete the first entry of an array.

[Peter W A Wood]

I have an array which contains a second array. (myArray[“numbers”][]). The 
numbers array is a traditional array with elements 1..n. I want to remove the 
first element of the numbers array and shuffle all the others up. Is there a 
simple way of doing this in LiveCode (equivalent to the shift() function in 
JavaScript)?

I looked in the dictionary and found delete  but couldn't get it to 
work, perhaps because I am trying to do this in a function that takes the array 
as an argument.

The essence of the function is:

function shift @pList
  local tItem
  put pList[“numbers”][1] into tItem
  delete pList[“numbers”] 1 ## Is this the 
correct syntax?
  return tItem
end shift

If I can get delete to remove the first element of the array, will it 
automatically change the index of the remaining entries?

Thanks in advance.

There are two problems with keeping the blog fresh. The first is that people

It is easy enough to do, if the JavaScript calls the LC Server Script. I 
believe that pushing content from the server to the browser can be achieved 
using the HTML5 WebSocket API (which will be a lot more complicated).

Tim doesn’t really have a choice over which version of the server to use with 
the On-Rev service. The version is chosen by LiveCode.

I suspect Tim will need to wait until LiveCode update the server before porting 
his scripts to .lc

Given Mark’s earlier explanation, it is difficult to see how the IDE can be MIT 
licensed. After all, it is just a stack and if other stacks run with the 
Community engine can only be issued under the GPL, surely the IDE can only be 
issued under the GPL if it is run by the Community engine? In fact, surely 
anything distributed within LiveCode Community must be under the GPL?

I should have shown the code that I ran in the message box (multiline):

put "0" + 0 into tVar1
put tVar1 is really an integer

It returned false.

I added a test to my LiveCode tests. It also fails:

MT.startTest "Is Really 1"
put "0" + 0 into tTemp
MT.assert tTemp is really an integer
 MT.endTest

Should I open a bug report?

The current implementation appears to differ a little from the above. You need 
to specify integer or real as number is not currently supported.

When I try “0” + 0 in the message box only “is really a string” returns true, 
“is really an integer” returns false.

I’m guessing that engine keeps a track of the type that each value is currently

I was mis-using it for general (simple) runtime assertions when I wish to call

Sadly it seems that the World was not ready at the time for a way to painlessly 
distribute both apps and data over what would now be considered very thin 
wires. Current App Stores and Web Push Notifications offer little more than the 
Rebol/View desktop and the even more advanced (IOS) Internet Operating System 
did more than ten years ago. The have a better looking interface and they can 
collect money. Probably nothing that couldn’t have been quite easily added to 
IOS. If only Carl had found a partner whose marketing prowess was the equal of 
his technical prowess.

Over the years, Rebol has become a general purpose development tool and its 
network roots have withered. I see a comparison with LiveCode which has grown 
into a general purpose development tool from its multimedia roots.

I believe Rebol (and what I see as it’s successor Red) has two significant 
advantages over LiveCode for writing domain-specific dialects., 

The first is that in Rebol values (not variables) are strictly typed. Values 
must be loaded in Rebol, once loaded a value is typed (e.g. integer). An 
integer can only be treated as a integer, there is no typecasting mechanism. As 
I understand, LiveCode has very few types, mainly everything is a string except 
for arrays and (maybe) objects. (I say maybe as my knowledge of LiveCode is 
insufficient in the area of how Objects are stored.)

The second is Rebol’s parse function which operates on loaded data and can 
match on both data and datatype. This is a huge advantage in writing domain 
specific dialects. (Parse also operates on strings and can do 99% of what can

Thanks for that suggestion. I might switch to IsList rather than List? etc. It 
would seem better to use an xTalk convention than a “foreign” one.

Thanks for this tip. Displaying one record in my stack fills a card. I don’t 
think that I could adapt a data grid in this case.

I believe that it would be a very worthwhile addition. An implementation in the 
engine would be far, far superior and orders of magnitude faster than anything 
I can come up with in LiveCode Script.

That is correct

The list is not circular. I am used to such functionality from Rebol (and now 
Red) whose list processing is ,I believe, highly influenced by Lisp.

Again, I am influenced by Rebol. Most of its functions which return true or 
false end with a ?. Some which return data such as length? also end in a ?. 
These latter are the cause of regular discussion in the community as to being 
renamed with -of at the end. Personally, I prefer length? over length-of (or 
lengthOf in LiveCode’s case).

I was surprised to read this as I started using this convention when one of the 
LiveCode team commented on somebody’s code that used the same convention and 
said “some people in the office have started using it”. Of course, I can no 
longer find the comment.  If you think it is an unwise convention to use to 
avoid name clashes, I will adopt another one. Any suggestions as to a good 
approach/

[ANN] LiveCode List Processor

[Peter W A Wood]

I decided to convert a small card-based database stack to a “proper” database 
using SQLite. I immediately missed the next/previous card navigation features 
which were ideal for browsing the small database.

LiveCode chunking is great for handling lists but, as far as I can tell, is 
missing forward and backward navigation through lists. I decided to write a few 
simple functions to come up with such a mechanism. 

I suspect that there may be an existing way to navigate forwards and backwards 
through a list but I just can’t find it. I’ve put together a very simple, 
completely unoptimised start of a LiveCode list processing library. It contains 
only a handful of functions. You can find it at 
https://github.com/PeterWAWood/LiveCode-ListProcessor 
.

Perhaps you would be kind enough to let me know of existing ways to achieve 
what this small library does before I spent more time developing it?

Regards

Peter

The 1001 Things To Do With LiveCode All Time Top Ten

[Peter W A Wood]

Even though I haven’t been able to spend much time on 1001 Things To Do With 
LiveCode recently, the blog is still getting an average of 80 visitors per day. 
I thought you might like to see the all-time top 10 pages visited.

The more recent entries in the blog have a high percentage of commercially 
available apps written in LiveCode and few very own-use or hobby apps. The 
original purpose of the blog was to show people who had never programmed before 
what could be achieved with LiveCode and to stimulate their imagination as to 
what they could do with LiveCode.

If you have used LiveCode to write an app for your own use or for your hobby 
perhaps you would be kind enough to send me a screenshot and a short 
description. I will try to find the time to add it to 1001 Things You Can Do 
With LiveCode.

The main difference between my set up and yours is the keyboard operator

Is it safe to return an array from a function?

[Peter W A Wood]

I understand that arrays are passed by reference in LiveCode not by value. I 
assume that is also that case if you return an array from a function (i.e. the 
reference to the array is returned not its content). When I tried to return an 
array from a function, I found that not only you can do so but multiple calls 
of the function provide different arrays. As the array being returned from the 
function is local to the function, I’m guessing that LiveCode is creating a new 
local array for each function call and returning a reference to the local 
variable.

Here is the code that I ran under LiveCode Server:

function returnArray
  local a
  put 1 into a[1]
  return a
end returnArray

put returnArray() into b
put b[1] & return   —> prints 1

put returnArray() into c
put c[1] & return   —> prints 1   

put 3 into c[1]

put b[1] & return   —> prints 1
put c[1] & return   —> prints 2

Is it safe to use such a technique or will the reference to the array become 
invalid at some stage?

Peter

LiveCode 8 Global Jam

[Peter W A Wood]

After reading the announcements, I am looking forward to the LiveCode 8 Global 
Jam and helping to prepare LiveCode 8 for release through reporting bugs.

As I’ve already reported a handful of bugs relating to LiveCode 8, I thought 
I’d take a look and see how many LiveCode 8 bugs there are in total. As I 
understand, LiveCode 8.0 is based on LiveCode 7 so I performed a search of the 
LiveCode Quality Centre for all bug reports against version 7.0.0 DP 1 and 
above which are not yet resolved.

I was surprised when the search returned 674 bug reports that met the criteria. 
Perhaps the search criteria I used could be improved. I can see that some of 
the 674 are enhancement requests but I can’t work out how to exclude them from 
the search. From a quick glance, I don’t think that there can be much more than 
50 enhancement requests so there still seems to be at least over 500 unresolved 
bugs.

Hopefully, many will get fixed during the Global Jam (and shortly afterwards) 
as the engineering team focusses on bug fixing rather than adding new 
functionality.

I’m still looking forward to the Global Jam but I’m a little worried that the 
LiveCode 8 release isn’t as close as the Global Jam announcements suggested.

Peter

If the rectangle doesn’t always appear in the same location or is not always

Thanks Klaus. Co-incidentally, Bernd also pointed this out to me. It seems the

Yes. You will need a Github account and then fork the Github repository. You 
can then edit the documents on-line. Once you have finished editing the 
documents, you will need to create a Pull Request. The LiveCode team will then 
decide whether to accept or decline your changes.

One thing that is needed for your changes to be accepted is to for you to enter

You can make better use of Git by downloading the repository onto your own

 In case anyone is interested:
 
 It was using a content type of 'application/json’ which would have made sense 
 if the PHP script was written to accept the json data directly.
 
 However, it was expecting the POST data to be encoded in name/value format: 
 variableA=valueAvariableB=valueB.
 
 In this case, it required the json data stored in a variable called json:  
 i.e.  json=json data
 
 Changing the headers as follows before the POST resolved the issue:
 
  set the httpHeaders to “content-type: application/x-www-form-urlencoded
 
 As I mentioned to Jacque, the json data itself needs to be urlEncoded.

 I'd thought of that too. I'll ask the PHP guy to set up an http URL.

I don’t think it is a problem with HTTPS. With Google and Stack overflow’s 
help, I found this website - http://httpbin.org - you can send a POST request 
to https://httpbin.org/post and it will return the POST data to you (in JSON). 
I ran your test against both the http:// and https:// URLs and both worked.

 The other difference is the UTF8 encoding, but it's my understanding that 
 servers always expect to receive that.

I don’t think that all servers expect to receive UTF-8. The character encoding 
can be specified in configuration files.

 Thanks very much to you and Charles for your tests. I agree with Charles that 
 it may indicate there is something wrong with the PHP script. If I give him 
 the simple echo script that you posted here, is that a good test?

It is possible but this may be more useful:

PHP:
?php 
  var_dump($_POST);
?

It will return the POST data received by PHP. For example:

LiveCode Message Box:

put textEncode({   quote  é  quote  : 1}, UTF-8) into tJSON
put json= before tJSON
post tJSON to URL http://localhost/jacque.php;
put textDecode(it, UTF-8)

This is what it returns:
array(1) {
  [json]=
  string(10) { é: 1}
}

Hope this helps.

 This works fine in LiveCode 7.0.3. I’ll download 7.1RC1 and see if it works 
 there too.

Apart from the difference in LiveCode versions, there is one other difference 
that may be significant. I am using HTTP on my machine not HTTPS. There have 
been some bugs in LiveCode 7 HTTPS support. Is it possible for you to run your 
test using HTTP to access your client’s server?

 Here's a test. This posts just fine in LC 6.x but fails in 7.0.6 and 7.1rc1.
 
 Make a field with this in it:

 Now put this into a button or card script:
 
 constant kServerURL = https://www.domain.com/results.php 
 https://www.domain.com/results.php  --### use a valid URL here

  post tData to kServerURL
  put it into tResponse
  put the result into tErr

 If someone can test this against a simple echo PHP maybe it will tell us

I ran a very simple test using the message box and a very simple PHP script. I

In the message box (using LC 7..0.3)

post textEncode(json={  quote  é  quote  : 1}, UTF-8) to  URL

put textDecode(it, UTF-8”)

The PHP script:

The result in the message box:

This would indicate your issue is not caused by a bug.

I’m not sure if you are URLEncoding the data … that certainly seems to cause a

Revised LiveCode
put textEncode({   quote  é  quote  : 1}, UTF-8) into tJSON
put json= before tJSON
post URLEncode(tJSON) to URL http://Localhost/jacque.php;
put textDecode(it, UTF-8”)

Result 
PHP sends back an empty response.

Hope this is of some help.

LIVECODE KICKSTARTER REPORT CARD -Version 4

The first thing to note is that LiveCode Ltd has open-sourced LiveCode under 
the GPL licence. It is freely accessible on Github.

The second thing to note is that the majority of the Kickstarter rewards have 
been delivered. Only delivery of printed copies of a new updated dictionary 
after final Kickstarter project delivery remains to be completed.

There seems to have been three other major deliverables promised in the main 
campaign:

Deliverable Status
Re-engineer the whole platform  Completed
A new technology: “Open Language”   Early alpha of the 
pre-requisite LiveCode Builder released (LiveCode 8.0)
Open Language 
will be in a release after LiveCode 8.0
A new visual editor Early alpha released 
(LiveCode 8.0)

There were a number of deliverables promised through stretch goals which were 
met:

Deliverable Status
Resolution Independence Completed
Pluggable ThemesPluggable Themes will 
be in a release after LiveCode 8.0

So I was wrong and the rewards were connected to the project after all.

I wonder what “the final Kickstarter project delivery” means in practical

I will update my report card.

 Does after LiveCode 8 mean 8.1 or does it mean 9 or maybe 10? Because 
 that could make quite a difference.

It means that I don’t think it is going to be in any of the LiveCode 8.xx 
releases based on my memory of snippets of information on this list and in the 
forums. (Which could well be wrong).

I didn’t know whether to use LiveCode 9 or LiveCode 10 for the major release 
after LiveCode 8. I remember it being mentioned by one of the LiveCode team 
that “Open Language” was going to be such an improvement that the release of 
LiveCode that included would be called LiveCode 10. (To be fair to the LiveCode 
team, this was said before Windows 10 was announced as the name for Windows 8 + 
1).

Open Source Kickstarter Report Card (Updated)

 Nope… I presume the goal will be bumped to Windows 10???

Perhaps there is no need for a replacement. After all, it looks to me that you 
cannot sell GPL licensed software through the Windows App Store so LiveCode 
will be motivated to include Windows 10 support as it could help them sell more 
indy licences. (Assuming that Windows 10 and its appstore takes off).

Re: Open Source Kickstarter Report Card (Updated)

[Peter W A Wood]

There have been quite a few comments and clearly a number of different views 
amongst members of the community. I would like to add my perspective.

The LiveCode Kickstarter campaign was very unusual in that the LiveCode could 
fulfil all of the rewards without actually having to complete the project. The 
rewards consisted of gifts and existing LiveCode products.

In one sense, LiveCode completed the Kickstarter campaign when all the rewards 
had been delivered. I’m sure that Kickstarter would take this view.

LiveCode kept to the biggest promise it made, LiveCode has been open-sourced 
under the GPL and is freely accessible on Github.

That leaves the other promises made during the Kickstarter campaign. Some made 
initially, some made as stretch goals. I have no doubt that these promises were 
very genuine. Clearly, LiveCode hasn’t been able to deliver them in the time 
they expected. This could be to any number of causes; under estimating and 
resources not being available being the most likely.

To their great credit, the LiveCode team still appears to be committed to 
meeting its Kickstarter promises even though the funds raised to do so must 
have run out a long time ago.

My concern is that it is human nature to push promises made a long time ago to 
the back of our minds. If my report card serves any purpose, it is simply to 
keep the promises in view. 

I would like the promises to be kept. However, if LiveCode were to give a 
reasonable explanation (with an apology) why a promise could no longer be met, 
I would accept it given that I got my rewards, LiveCode has been open-sourced, 
and many of the “feature” promises have been met. 

Peter

 I couldn't find anything definitive on that.  I did find some older articles 
 about Win8 licensing suggesting FOSS was prohibited, but I also found this 
 one from 2011 that says the opposite:
 
   Windows 8 Store will allow open source apps,
   unlike iOS and Mac App Stores
   ...
The section in question states that apps released under a license
from the Open Source Initiative (GPL, Apache, etc.) can be
distributed in the Windows Store. Further, it says that the OSI
license will trump the Microsoft Standard Application License
Terms, namely the the restriction on sharing applications.
 http://www.extremetech.com/computing/108551-windows-8-store-will-allow-open-source-apps-unlike-ios-and-mac
 
 And that was back when Ballmer was still there.  Since Nadella took the helm 
 Microsoft has fallen in love with Linux, started moving their dev tools to 
 open source, and is partnering with Ubuntu as a key component of their Azure 
 cloud platform.  (No, really, it's like hell froze over in a flock of flying 
 pigs - the photo here is priceless, something no one ever expected for 
 decades: 
 http://news.softpedia.com/news/CEO-Satya-Nadella-Microsoft-Loves-Linux-462754.shtml
  )
 
 Anyone have a definitive notice on this, preferably one from Microsoft 
 themselves?

I interpreted this clause from the latest Windows Store App Developer 
Agreement, to mean that GPL software cannot be sold via the App Store:

d.  FOSS Software. If your App includes FOSS, (i) you are responsible for 
compliance with all applicable FOSS license terms, including any source code 
availability requirements, and (ii) it must not cause any non-FOSS Microsoft 
software to become subject to the terms of any FOSS license.
I could well be wrong though.

 I keep hearing talk about that, but it's not on the Road Map and given the 
 number of tasks in the queue it may be a long time before it shows up.

Any new visual editor designed around today’s usability standards would 
include this, even older ones like Delphi do. 

  2. Integrated Version Control
 
 Looks like lcVCS is a more generalized solution than what LiveCode Ltd. is 
 including with their Biz package, so we're on our way on that one.

Again today’s usability standards for visual editors would include git 
integration as a minimum, even for visually designed elements. Sure this would 
require LiveCode to add object state serialisation Of the IDE’s I know both 
Delphi and Xcode include object state serialisation. Vector graphics drawing 
tools do. Again it is something you would expect in a modern visual editor.

  3. Support of Multiple targets (like Xcode)
 
 What are multiple targets in an IDE?

Very much as Monte said. Specifically would be the ability to define both test, 
debug and distribution targets. The test target would cause an automated test 
suite to run, the debug target would build and run a version including 
additional debugging code etc.

With LiveCode’s cross-platform credentials, it should be possible to select the 
iOS test target (one for each device), click-on run and your stack should be 
run in an iOS simulator. Similar for Android.

Again, I see these as features to be part of today’s usability standards.

The issue here is that the promise of a “new visual editor designed around 
today’s usability standards” is extremely broad. It means different things to 
different people depending on their context. I think it’s great from a 
marketing perspective, it has something to attract a lot of people, and it's 
horrible from a customer satisfaction perspective as most people will be 
disappointed when it doesn’t meet their expectation.

Peter

 Seems very accepting of FOSS.  I can't imagine anyone would try to distribute 
 something that places restrictions on the OS vendor.
 
 I haven't spent much time looking, but I haven't heard any objections from 
 the Free Software Foundation, and they're usually quite vocal about such 
 things.

I believe that the statement “ it must not cause any non-FOSS Microsoft 
software to become subject to the terms of any FOSS license.” would 
specifically exclude the use of GPL licensed software -

Open Source Kickstarter Report Card

[Peter W A Wood]

Following LiveCode’s announcement of its Business Application Framework, there 
has been quite a few comments regarding the fulfilment of promises made during 
the Kickstarter open source campaign. It’s a long time since the campaign and 
it is easy to get an incorrect perception. So I thought that it would be worth 
going back, seeing what was promised and what had been delivered. 

I’ve come up with a report card based on the Kickstarter web pages, LiveCode’s 
road map and from comments made on the mailing lists and forums by LiveCode 
staff. I relied on my memory for the latter so the status that I’ve noted may 
not be quite correct. By posting it to the mailing list, I’m sure that any 
misperceptions I might have will get corrected. I hope so as I much prefer to 
have a clear picture of where things stand.

The first thing to note is that all the Kickstarter rewards have been delivered.

There seems to have been three major deliverables promised in the main campaign:

Deliverable Status
Re-engineer the whole platform  Completed
A new technology: “Open Language”   Early alpha of the 
pre-requisite LiveCode Builder released (LiveCode 8.0)
Open Language 
will be in a release after LiveCode 8.0
A new visual editor Early alpha released 
(LiveCode 8.0)

There were a number of deliverables promised through stretch goals which were 
met:

Deliverable Status
Resolution Independence Completed
Pluggable ThemesPluggable Themes will 
be in a release after LiveCode 8.0
Cocoa   Completed
Physics Engine  Physics Engine will be 
in a release after LiveCode 8.0
Windows/Phone 8 Theme   Windows/Phone 8 Theme will be 
in a release after LiveCode 8.0
Vector Shape Object Vector Shape Object

Multi Channel Sound OS X : Linux : Windows

which I’m unclear and any mistakes I have made.

It may be this bug - http://quality.runrev.com/show_bug.cgi?id=15162

Re: Livecode and UTF8

I did not reply sooner as I’m not such an experienced LiveCoder. Also, I am 
concentrating on learning LiveCode versions from 7 onwards. Handling Unicode is 
much, much easier in those versions. 

In the code you posted here, you appear to have used uniDecode where you needed 
to use uniEncode.

I ran this in the message box in LiveCode 8:

put numToChar(226) into tString -- E2 hex
put numToChar(128) after tString -- 80 hex
put numToChar(156) after tString -- 9C hex
put  unicode uniEncode(tString, UTF8”)

It successfully displayed this:

“

I am not familiar with using Unicode in the older versions but noticed that you 
typed “useUniCode” instead of “useUnicode” in the code example in your message.

I hope this helps to get you started.

 Hi,
 
 I have an app that works with old fashioned text i.e. characters with a code 
 value of less than 128.  Recently I enabled cut and paste and the app gets 
 confused it text is pasted in with character values  127.  I have done the 
 obvious and an filtering out all characters with an Ascii value of 127 but 
 in the longer term I want to convert a few high bit characters to a low bit 
 versions e.g. smart quotes to dumb quotes.
 
 Some of the text that gets pasted from my email client is in UTF8. I have 
 done some web research and now know a little about UTF8.  I have written a 
 routine that captures any UTF8 code patterns and passes the UTF string to a 
 routine for conversion.
 
 A UTF8 string may be between one and four bytes long and every byte has a 
 value greater than 127.  I wish to extract the UTF character value and use 
 the value to do the conversion.  My question is: does livecode have any 
 method of converting  a UTF8 character string to either a UTF16 string or to 
 the numeric value of the character which I believe is the same if leading 
 zeros are ignored?  For instance a smart open quote appears in my data as a 
 series of three bytes : [E2-hex,80-hex,9C-hex] the numeric value of the 
 character is encoded within the bits of the three bytes and will take some 
 bit shifting to extract : the UTF8 string decodes to 201C-hex or 8220 base 10.
 
 At present I am working with Livecode 6.7 and have read about and tried the 
 uniEncode and uniDecode functions.  The description of these functions does 
 not make any sense to me as they seem to be about adding or removing every 
 other byte which can't work with UTF8.
 
 I have tried various versions of the following button code attempting to get 
 a result of 8220 base 10:
 
 on mouseUp
 put numToChar(226) into tString -- E2 hex
 put numToChar(128) after tString -- 80 hex
 put numToChar(156) after tString -- 9C hex
 
 Set the UseUniCode to true
 
 put source string :   tstring
 
 put uniDecode(tString,UTF8) into tResult
 
 put CharToNum(tResult) into tNumberResult  -- seeking value 8220 in base 
 10
 
 end mouseUp
 
 So do I have to knuckle down and start bit shifting?
 
 thanks for reading
 Simon

The MasterLibrary is impressive, I should have looked at it before.

The function didn’t seem to have the exact format that I needed but it was a 
good stimulus to write one that meets my needs. I wanted to format the numbers 
in what I call accounting format - thousands separators with negative numbers 
in brackets (or parentheses depending from where one hails). 

Thanks to LiveCode’s chunking the function is very short, dealing with the 
arguments takes almost as much code as the function. I include it here in case 
it is of use to others. I’m sure it could be improved and would welcome any 
suggestions.

function numToAccounting pNum, pDecimalSeparator, pThousandSeparator 
# Purpose:Converts a number to accounting format
# Inputs:
# pNum  The number to be converted
# pDecimalSeparator The character to be used, default .
# pThousandSeparatorThe character to be used, default ,
# Returns:  The number in accounting format rounded 
toplevel
#   decimal places
  local tCount
  local tDecimalSeparator
  local tNum
  local tStart
  local tThousandSeparator
  
  # set the separators
  if pThousandSeparator is empty then
put , into tThousandSeparator
  else
put pThousandSeparator into tThousandSeparator
  end if
  if pDecimalSeparator is empty then
  put . into tDecimalSeparator
else
  put pDecimalSeparator into tDecimalSeparator
  end if
  
  #format the numbers
  put format(%.2f, pNum) into tNum
  put tDecimalSeparator into char -3 of tNum
  put 0 into tCount
  put the length of tNum - 3 into tStart
  repeat with i = tStart down to 1
add 1 to tCount
if tCount = 4 then 
  if char i of tNum  = - then exit repeat
  put tThousandSeparator after char i of tNum
  put 1 into tCount
end if
  end repeat
  if pNum  0 then
put ( into character 1 of tNum
put ) after tNum
  end if
  
  return tNum 
  
end numToAccounting

Programatically complete an answer dialog ?

I have a stack which requests the user to enter some text into an answer 
dialog. I am trying to test that stack from another stack. Is there a way to 
programatically enter text into an answer dialog?

Another way of asking this question is: Is an answer dialog simply a stack? If 
so, does anybody know the name of the stack and the name of the text field? (I 
can guess the name of the button would be the label displayed on them).

Thanks, Hugh

I’m trying to find the best way to clear all the fields in which data can be

if not the lockText of Field y then

 As you will have gathered, there is no label property as such, simply a

Problem with arrayDecode

[Peter W A Wood]

I am having problems with encoding and decoding an array when I save the 
encoded data to a file and read it back. Here is a simple LiveCode Server 
script that shows the issue:

#coding:utf-8

set the outputLineEndings to “lf”   
# OS X
set the outputTextEncoding to “utf8”# OS X

put data.db into preferences[database”]
put arrayEncode(preferences) into URL “file:temp.txt
put URL file:temp.txt into encodedPrefs 
if encodedPrefs is not empty then 
put arrayDecode(encodedPrefs) into prefs
put The decoded data contains:  prefs[database]  return
end if

put data2.db into preferences[database”]
put arrayEncode(preferences) into encodedPrefs
put arrayDecode(encodedPrefs) into prefs
put The decoded data contains:  prefs[database]  return

This is what the script outputs:

peter$ test/test.lc
The decoded data contains: 
The decoded data contains: data2.db
peter$ 

Any suggestions to what I’m getting wrong or is it a bug?

 The smart-alec answer would be text file or as you seem to be referring to
 a large amount of data, a database ;-)
 
 In the Model View Controller way of doing things the data (model) is all in
 one location so as to avoid the problems you are facing. It wouldn't matter
 which field (view) was in which group (view) of whatever stack (view), the
 call (controller) to get the data would be exactly the same. It's why I
 moved to dbs a long time ago, even simple stacks I use a sqLite db; avoids
 all these hassles plus you get a host of db bonus features thrown if for
 free.
 
 Probably not what you wanted to hear ;-(
