Re: LC-apps for HC

[kee nethery via use-livecode]

Livecode is a program for creating programs.
MacPaint is a program for creating images that as far as I know ran on 68K 
macs. Not sure it ever ran on PPC Macs. Not sure if MacPaint images can import 
into Livecode.
Asking if MacPaint works in LC doesn’t make sense to me.

Re: Troubleshooting revIgniter library functions

[Keith Clarke via use-livecode]

Brilliant - thanks for the analysis and syntax corrections, Ralf. 

That’s clarified more of the LCS / MVC ‘plumbing' and provided a worked example 
I can repeat as I start to build-out the app proper.

Much appreciated
Best,
Keith

Re: Insert a "Waiting/Busy" Icon Into Browser Widget

[hh via use-livecode]

The following works tested here on desktop, should work everywhere where the 
browser widget works.

1. Overlay browser widget "browser" with a browser widget "loader" (that 
displays a loading animation).
2. Load the slow loading url into widget "browser".
3. Hide widget "loader" by browserDocumentLoadComplete of widget "browser".

For example:

Good move.

The more you stick with language features common to both the Server and 
desktop LC engines, the greater opportunities there are for crafting 
very helpful test harnesses you can use right in the IDE without having 
to deal with the building-a-ship-in-a-bottle experience of LC Server.

Thanks Alex,

For my first web services I implementing the "start using" of library stacks 
method back in the day. Like you I moved to "start using" of script only

Hmmm I hesitated to reply earlier, just in case there are subtleties I might 
get wrong and mislead you - but here goes.

include / require are essentially ways to include the text of the included 
file. Include will do that - and do it every time you use it 

so you could have a trivial nonsensical example like ...

mydebug.lc   - a file which will dump out a bunch of variable info ...

>  put "Data is:" && gVar1 && gVar2 && gArray[temp]
>
and use it as

.
doSomeHandler gVar1, 17
-- and check what the current status is now include "mydebug.lc"
doSomeOtherFunctions
-- and check again
include "mydebug.lc"


note that you can now change the file to do any other logging you might want, 
and each occurrence will be changed.

NB - I have never used 'include' except in a few places where I should have 
used require :-) And I've never wanted to use it as I just described :-) :-)

require is similar, but the file contents will only be inserted the
*first* time; so it's useful to include the source of library-like functions. 
And you don't need to worry if you do this in multiple places. I used to use 
this a lot.

Note that include and require are both specific to LC server. I basically no 
longer use them, now that we have script-only stacks. I now develop 99% of all 
LC server functionality as script-only stacks, testing in either the IDE or via 
LCServer as needed. And for this, you use "start using" just like in the IDE 
world.

-- Alex.

P.S. Note - there are (I think) strange subtleties in using globals and/or 
script locals in include'd / require'd files - very confusing, and I suspect 
it's a bug - but  couldn't quite come up with a reliable mental model or 
example; that was when I just converted to script-only library stacks.

I doubt it.  IIRC the format was directly dependent on QuickDraw - from 
Wikipedia:


  Applications using QuickDraw will still run under OS X 10.8
  through macOS 10.12; however, the current versions of Xcode
  and the macOS SDK do not contain the header files to compile
  such programs.

https://en.wikipedia.org/wiki/Apple_QuickDraw


This is one of the benefits I've come to appreciate with open source: 
data longevity. When formats and the code needed to operate on them are 
free and open, data can never die.


Proprietary formats only live as long as the vendor chooses to support them.

I have a hard drive in my archives filled with data dependent on 
software that no longer runs on any modern OS.

Re: Troubleshooting revIgniter library functions

[Ralf Bitter via use-livecode]

Hi Keith,

seems that you have overlooked that your library  
handler is not a function, see line  

put somehandler() into gData["testlib"]

in your controller.  

Furthermore don’t forget to adjust the name of your library  
initialisation handler to “rigRunInitialteslibConfig”.  


Ralf

designer rather than sub it all out using vb.net and SQL server.
2) Are there any examples of how to do this?

Thanks in advance.

Re: Setting hidden of lines very slow

[Geoff Canyon via use-livecode]

Why do you need to simulate non-contiguous selections? Set the
listBehavior, multipleHilites, and noncontiguousHilites of the field to
true and then you can do things like:

set the hilitedLines of fld 1 to 1,3,5

But to your original question, you should use:

repeat for each line L in the htmlText of fld 1
  -- put some htmlText after a variable based on what L contains
end repeat
  -- set the htmlText of fld 1 to the new htmlText

Or if you know what you want to do and don't need to check the existing
textColor and hidden, just:

repeat for each line L in fld 1


Here's an example of what the htmlText looks like for a field where the
first line has a font color and the second line is hidden:

test
this
thing

So if you don't need to check the existing state your code would look
something like this:

put 0 into i -- if you need a line count
repeat for each line L in fld 1
 add 1 to i -- again, if you need a line count
 if  then
  put "" & L & ""
& cr after newHTML
else
   put "" & L & "" & cr after newHTML
end if
end repeat
set the htmlText of fld 1 to newHTML

In jQuery it’d be something like $j(‘div #id’).text(); selecting the field’s

Re: LC-apps for HC

[Bob Sneidar via use-livecode]

I'll jump in here. 

Porting/opening Hypercard stacks is a convenience. The primary issue is that 
Hypercard was optimized to index every text of every card in a stack to make 
finding information easier. New records? New cards. 

Livecode? Not so much. In fact, not at all. There will be performance issues. 
But at least your field and button layouts will be intact, and you scripting 
*should* work out of the box. 

At that point, your next task will be to refactor your app to switch to a 
database oriented app with single form layouts as opposed to multiple cards as 
records. Getting the information out of your cards and into a database, 
although not difficult, will have to be scripted. So far as I know, there is 
nothing that can "automagically" do that for you.

Insert a "Waiting/Busy" Icon Into Browser Widget

[Sannyasin Brahmanathaswami via use-livecode]

I watch with interest all of HH amazing thing he does the browser widget. 
Haven't had time to keep up. But I have a common use case that I can't figure 
out that possibly relates

a) On mobile, let's say you have connectivity… It may not be fast at the 
moment, but it is it good enough for you to wait.
b) We "install" a web URL on the browser widget.
c) Now… the page has a big pay load… usually a lot of JS coming thru first, 
before it renders at anything.  
Two examples
 One is a badly designed site .. some "Wicks" platform : 
https://www.hindouisme.org/ 

   The other is a huge HTML5 application
   https://mydigitalpublication.com/publication?m=45852=1

d) You get a "white screen" as the browser is busy getting resources.
e) User thinks it has "hanging 

I have tried using native LC to display a busy "spinner" . But inevitably the 
browser takes over the CPU and such things as

browserFinishedLoading pUrl 

 don’t work.

So, now, is possible to "insert" JS script into a browser, right at "init" to 
display a spinner, while we wait for the full page render?

Re: Setting hidden of lines very slow

[Kaveh Bazargan via use-livecode]

I am simulating a non-contiguous selection of text with a "Find all" button
that sets the style of all found items of text.

Then I want to inspect those "selections" only but showing the paras that
contain them and hiding all other lines. So I have a full view and a
"compact" view that the user can choose by clicking a button

LiveCode Server

[Ralph DiMola via use-livecode]

Ahh... I see that the revIgniter library is the way to go for my number 2
question and I am immersed in the docs. But I'm still wondering about my
question # 1 (differences between "Include", "Require" and "Start using")

I've been using LiveCode Server for a few years now with great success as
various web services from LCS. I started this when I was a relative newbie.
I access my library stacks via "Start using".
1) Can anyone shed some light on the subtle differences between "Include",
"Require" and "Start using"? The docs are not clear to me.

I'm starting a new project using interactive web pages. I have an in house
web designer that I need to show how to call LC server scripts to populate
web pages. I would rather use LC Server and MySQL and my on-staff html
designer rather than sub it all out using vb.net and SQL server.
2) Are there any examples of how to do this?

Thanks in advance.

Re: Setting hidden of lines very slow

Did not know about textStyle which has opened a whole new world! Thank you
so much for ruining my weekend Trevor. ;-)

hh, I love the first solution, which shows the beauty of LiveCode. But the
speed is the same as before...

i will try htmltext too. A while since I worked with it.

Thanks again.

Re: Troubleshooting revIgniter library functions

[Ralf Bitter via use-livecode]

Hi Keith,

if you change the name of your library to Testlib.lc
and if you adjust the name in your controller respectively
all should work as expected.
There is a naming convention for library files, i.e.
camel case is not allowed, but it seems this is not
mentioned in the user guide.
Sorry for the hassle. Will fix that.

Re: Setting hidden of lines very slow

If showing *only* lines with colored text means that all others
are hidden then you could use:

...
set hidden of line i of fld "text" to \
(the textcolor of line i of fld "text" is empty)
...

Trevor's script would then read:
...
put (tTextA[i]["runs"][1]["style"]["textcolor"] is empty) \
 into tTextA[i]["style"]["hidden"] 
...

Try working with the styledText property.

```
put the styledText of field "text" into tTextA

# loop through paragraphs
repeat with i = 1 to the number of elements of tTextA
  # Check if first run has textcolor set
  if tTextA[i]["runs"][1]["style"]["textcolor"] is not empty then
# hide paragraph
put true into tTextA[i]["style"]["hidden"]
  end if
end repeat

set the styledText of fld "text" to tTextA
```

Re: Troubleshooting revIgniter library functions

[Keith Clarke via use-livecode]

Thanks Ralf (& Andre) for the responses.

I have read the user guide and understood more than I expected, given my basic 
HTML + jQuery + CSS background! I’ve also been learning more as I build my app 
out using user guide worked examples where they exist.

Thanks for the syntax for processing the response returned from the library - I 
know understand the central role of the controller page and how that call & 
response should work. 

Thanks also for the tip regarding the log, as that has proven more revealing… 
errors when attempting to load library files into any controllers.

Stripping back to basics, I have created a testLib.lc library file in the 
default system/application/libraries folder that contains just the prototype 
markup from the user guide.

My default controller is home.lc (copied from welcome.lc) which throws an error 
"Unable to load the requested library:Testlib” if I add 'rigLoaderLoadLibrary 
“testLib” ‘ to the home or index handler markup.

Any clues as to what I may have missed?  
Thanks
Keith

Re: Troubleshooting revIgniter library functions

[Ralf Bitter via use-livecode]

Hi Keith,  

in addition to Andre’s valuable tips I would like  
to comment that your approach should actually work,  
but be advised to make sure you include your custom  
library as described here:  

https://revigniter.com/userGuide/general/creating_libraries.html  

Furthermore you can leave your function as is i.e.  
call your library function within your DocLogin.lc controller like:  

put myDocLoginHandler() into gData["doc_token"]

For debugging purposes make sure the logs folder is writable,  
set the gConfig["logThreshold"]  in config.lc to 4 and check the  
log file in case something goes wrong.

Re: LiveCode equivalent to 'cron' for automated background functions?

[Andre Alves Garzia via use-livecode]

Keith,



The examples in the dictionary look potentially useful for a couple of 
lightweight activities I’d like to have ticking-over in the background on my LC 
Server, pending page visits.


You shouldn't have the CGI engine hogging up like that, thats not how 
web stuff is supposed to work. First, Apache (or whatever you're 
running) will kill the process after some seconds if it fails to exit on 
its own. Second, it is a waste of resources. Imagine that you have this 
running for every request that is made, so each time a user requests 
your site, your LC Server engine hangs in the background for a while, 
hogging up system resources.


LC Servers should reply as fast as possible and then exit. If you need a 
long running process to do some administrative stuff regularly, then, 
consider building a little script and running that as a real proper 
cronjob on the server, not tied to visits.


Cheers

andre

Re: Troubleshooting revIgniter library functions

[Andre Alves Garzia via use-livecode]

Keith,

RevIgniter is a normal LiveCode collection of libraries. Have you read 
the getting started guide at:


  https://revigniter.com/userGuide/overview/getting_started.html

It will walk you through the concepts of MVC and how they are used in 
RevIgniter. Basically your models are the stuff that touch data, views 
are the templates that are shown to the user and controllers are where 
the business logic is. You can also have libraries. So if your DocLogin 
has a function that returns a token, you can call it from a model or a 
controller and get the value.


There is really no "1 minute explanation" that will clear it all, 
RevIgniter is quite easy and consistent but it requires you to go over 
its documentation at least once. Some URLs of interest are:


  https://revigniter.com/userGuide/overview/appflow.html

  https://revigniter.com/userGuide/tutorials/chat.html

I recommend doing the tutorial a lot.

Cheers

andre

Folks,

My use case is to share public FAQs from specific pages designated as public in 
our knowledge base. I have a basic LC desktop prototype that I’m migrating to 
LCS + revIgniter. The desktop stack includes a single function stack script 
that logs into the KB server as a proxy ‘public user' and returns an access 
token string for subsequent page requests.

To migrate this across to the server environment, I have simply transferred the 
stack script into a DocLogin.lc library file, replacing the final 'return “token”’ 
with put tToken into gData[“doc_token”] I may have misunderstood the revIgniter 
docs that this is the way to get the data ‘back’ to the controller, rather than use 
the desktop-style function do & return to a library (or stack) file?

A DocLogin.lc controller file then attempts to call the above library and open a 
view file to check that the token is available via [[gData[“doc_token"] ]]

The controller is opening the view but the token merge field is not shown and 
adding the generic rigShowError “message” alerts that the library couldn’t be 
loaded.

I’d appreciate a steer as I’ve a feeling my approach here is fundamentally 
wrong for the LCS + revIgniter way of working.
Thanks

Re: Safari vs Browser Widget

[Andre Alves Garzia via use-livecode]

Dan,

I am not expert in the widget but I do know quite a lot about browsers. 
Those APIs are restricted access API which usually require some sort of 
configuration on the browser library you're using when building your 
product, which is a convoluted way to say that LiveCode HQ proabably 
needs to set something on libbrowser for this to work out of the box.


I have checked the LC source code and found that the browser 
initialization depends on some factory called `MCBrowserFactoryRef` 
which is an abstraction on the browser engine being used. In your macOS 
case, I don't know if it is using CEF or WebKit but it if is CEF then 
there is a "enable-media-stream" argument that is usually passed via 
command-line parameters but in our case it probably need to be passed 
via `t_args` in the calls to `CefExecuteProcess()`. I am sure there is a 
corresponding WebKit thing to do but I am not sure what.


These kind of switches are needed because Camera APIs are sensitive and 
can lead to privacy abuse and security exploits, so they tend to be 
disabled by default unless configured or asken for permission. In case 
of embeddable browser libraries, they usually lack the UI elements to 
ask for permission, so in their case it is is usually something you 
configure in code.


You might ask HQ to add the CEF param as a property for the widget. It 
might be easy to add.

Greeting!  I am hoping someone has an answer for this…

I am working on a HTML5 web page that accesses the device's camera.  When I 
open the url in Safari (on my Mac or iOS device), I am asked if it's ok to use 
the camera and everything works perfectly!   However, if I load this same url 
in the Browser Widget (or a plain native browser), it doesn’t ask to use the 
camera and it all fails.   Is this a limitation of the implementation of the 
browser in LiveCode, or is there a setting I have to set?

Thank you!
