Re: [revIgniter] revIgniter and LC8

[Ralf Bitter]

Sorry for coming late. The superfluous "then" keyword in
system/libraries/Input.lc -> _rigValid_ipv4() was overlooked
because server engine versions prior to 8 were forgiving and
didn't complain.
The bug is fixed since version 1.7.2. So, all of you who use
older versions need to fix this in case you intend to upgrade
the server engine to version 8.
Anyhow I recommend to update revIgniter to the latest version.


Warm regards

Ralf

Re: LC Server: Getting a file list when filenames use UTF8

[Ralf Bitter]

Seems that I can confirm your findings.
Did a test on diesel using server version 8.1.1-rc-2.
If there is a file "こんにちは.txt" the file list retrieved
is empty. To get a file list I have to remove the
Japanese file.

tsNetInit and LiveCode server

[Ralf Bitter]

Is the tsNet external working with LiveCode server?

Did tests using server version 8.1.1 rc2 on Mac OS X 10.11.6.
Seems that initialization (tsNetInit) doesn't work.
The result of tsNetGetSync is "tsneterr: Not initialised" although
tsNetInit is called prior to calling any other tsNet handlers as
described in the docs.

How to show the Windows 8 on screen keyboard in LiveCode?

[Ralf Bitter]

Shouldn't the on screen keyboard of Windows 8 tablets pop up automatically
on touching a text input control?
A client who installed a standalone built with LiveCode 6.7.1 on a Toshiba 
tablet
reports that the soft keyboard doesn't show up tapping a text input field.

Thought that, as a workaround, one possibly could start the keyboard exe
using launch or shell() like:

launch "C:/Program Files/Common Files/microsoft shared/ink/TabTip.exe"
yields "not opened"

or

get shell("start C:\Program Files\Common Files\microsoft shared\ink\TabTip.exe")
yields "The file "C:/Program" could not be found."

or

get shell("start tabtip.exe")
yields "The file "tabtip.exe" could not be found."


Double checked the paths but all this fails, though start tabtip.exe definitely 
works from
the Windows command shell in contrast to
start C:\Program Files\Common Files\microsoft shared\ink\TabTip.exe.

So, how do others show the on screen keyboard on Windows 8 tablets from
LiveCode standalones? Any insights appreciated.

Re: How to show the Windows 8 on screen keyboard in LiveCode?

[Ralf Bitter]

Hi Ralf,

the following code lets the Windows on screen keyboard appear (needed
for applications used in desktop mode:

--
set the hideConsoleWindows to true

# USE WINDOWS POWERSHELL
set the itemDel to "\"
put item 1 to -2 of $PSModulePath & "\powershell.exe" into tPowerShellPath
set the shellCommand to tPowerShellPath

get shell("start '" & $CommonProgramW6432 & "\microsoft shared\ink\TabTip.exe'")
--

Note the use of single and double quotes!


Sorry for soliloquizing but I thought this could be useful for others too.

Hi Kay,

actually there is a snippet for "switch", so
typing "s", "sw", "swi" etc. followed by a tab
should work, really. Then a placeholder for the
switch expression is selected. Subsequent
tabs select the first case value, the related
line of code and the placeholder for the
"default" code .

Re: [OT] Atom Text Editor for Script Editiing - First Impressions

[Ralf Bitter]

You are right, I use custom packages, mainly to keep
revIgniter stuff separat from LiveCode server syntax.
But I disabled my packages, enabled the one provided
by Peter Brett, restarted Atom and the snippet was there.

So, assuming you use the latest version (0.5.1) I am at a loss.

Hi Roger

no separate download needed. You can install themes (and packages)
within Atom in the "Install" section of the preferences.

Assuming you did choose the revIgniter theme from

of the preferences I have no clue what's going on.

Kay, if you see legal, lorem, module etc. this means that you
have chosen the "LiveCode Builder" syntax. In this case you
are right, there is no "switch" snippet.
In case you would like to write code for LiveCode server
you should choose "iRev". Then there is "switch" and lots of
other snippets.

Hey Ralf,

just use the right codec. Although Chrome plays
H264, the CEF browser does not.
Use ogg or webm instead.

PS: Did I already mention that the performance of the
CEF browser of LiveCode 6.7 dp4 on Mac seems to
be pretty poor?

CEF browser - how to allow cross origin requests using the file:// protocol?

[Ralf Bitter]

As you might know the new CEF browser doesn't support
access to local files (file://) using XMLHttpRequest.
Of course, JSONP would be a solution but not in my
special case.

I need to display local Keynote presentations (exported to HTML).
Keynote uses JSONP in case the protocol is file://. So, this
works with CEF. But there is one problem:
There is an annoying flicker on slide transitions. Same problem
with Chrome, this is nothing special with CEF in LiveCode and this
does not depend on the kind of transition.

Now, if you use a server and http://, Keynote uses Ajax and transitions
work fine. This means I need to remove the JSONP option and
tell the CEF browser somehow to allow cross origin requests
using the file:// protocol. With Chrome this can be achieved by using
a -–allow-file-access-from-files command line switch.

Does anybody know how to set this flag for the CEF browser
in LiveCode?

Re: Is someone using Coda 2 with syntax highlighting for livecode server scripts?

Peter,

code colorization (as well as code completion) is implemented solely for
server related parts of the language because the bundle is meant to be used
for working with LiveCode server files.
So, if you add " wrote:

[ANN] revIgniter v1.3.18b

[Ralf Bitter]

revIgniter v1.3.18b has been released.

Since the announcement of version 1.3.10b in September 2010
I kept silent to avoid augmented noise on this list.
Now I thought it may be time again and appropriate to remind
those interested in revIgniter that the framework is still alive and
continually improved.

So, here are the news:

revIgniter version 1.3.18b includes modifications of the Captcha
library, the Formvalidation library and the sitelinks plugin.
This means that the Captcha library now provides two flavors
of captchas, the rigRequiredR form validation rule accounts
for prefilled form fields, there are three new form validation
rules and the sitelinks plugin now additionally enables you to
use images instead of text for your navigation links.
Furthermore there are two bug fixes. Model file names are
no longer restricted to lowercase letters. Email message IDs
are now generated correctly.

Info and download as always at: http://www.revigniter.com/

[ANN] revIgniter v1.3.21b

[Ralf Bitter]

revIgniter v1.3.21b has been released.

This version includes a minor modification of the Output library.

If you ever asked yourself what the Hooks feature of revIgniter
could be used for, you might be interested in an addition to the
Hooks section of the User Guide which describes how to use
this feature to make revIgniter automatically minify output just
before it is displayed.

As the Quartam PDF Library recently went opensource I thought this
is a good opportunity to add an example to the Creating Libraries
section of the User Guide which describes how to integrate a custom
library, in this case the Quartam PDF Library, into revIgniter.

[ANN] revIgniter v1.4b

[Ralf Bitter]

revIgniter v1.4b has been released.

This is the first version which respects the latest
engine changes (LiveCode server version 4.6.3).
Lots of adjustments were made and the whole
Encrypt library is revised.

Keep in mind that this version is not compatible with
revServer (engine versions before LiveCode server 4.6.3).

Info and download at: http://www.revigniter.com/

Re: Using revIgniter with on-rev and multiple sites/domains

[Ralf Bitter]

Hi Keith,

every addon domain needs it's own revIgniter installation.
So, the revIgniter files go into public_html/yourAddonDomain.

Hope this helps.

Ralf

Re: Using revIgniter with on-rev and multiple sites/domains

[Ralf Bitter]

Keith,

to use the latest version (1.4b) of revIgniter with the
latest version of the server engine on On-Rev you
currently need to change the extensions of all files to .lc
(sorry for the inconvenience).
Note: This applies to revIgniter installations on On-Rev only.

The next revIgniter version will include the .lc extension.

[livecodeServer] new header error

[Ralf Bitter]

Hello,

please, could anybody confirm that "put new header"
is broken with the latest version of the server engine?

I get a "can't find handler (header)" error. 

"put header" still works, though.

LiveCode server: incorrect path environment variables on Lion

[Ralf Bitter]

Hi all,

can anybody confirm that LiveCode server 4.6.3 up to 5.0 has
incorrect path environment variables?

I did tests and compared server version 4.6.3, 4.6.4 and 5.0
with reserver (LiveCode server prior version 4.6.3).

The results using files at
http://192.168.178.38/~rabit/servervars.lc/test/ and
http://192.168.178.38/~rabit/servervars.irev/test/ respectively are:

LiveCode server (incorrect)
PATH_TRANSLATED: /Users/rabit/Sites/servervars.lc/test/
PATH_INFO: /~rabit/servervars.lc/test/

revserver (correct)
PATH_TRANSLATED: /Users/rabit/Sites/servervars.irev
PATH_INFO: /test/



Thanks for any info in advance

Re: LiveCode server: incorrect path environment variables on Lion

[Ralf Bitter]

Thanks Stephen but, as stated in the subject, I am solely
interested in what is going on on Mac OS Lion. I should have
mentioned that in the mail body too, sorry for the confusion.

So, has anybody installed LiveCode server on Lion and checked
$_SERVER["PATH_TRANSLATED"] and $_SERVER["PATH_INFO"]?

Thanks

Re: New browser

[Ralf Bitter]

Hi Jacqueline,

in case you mean the ability to call a LiveCode
handler from within the browser using the new
"revBrowserAddJavaScriptHandler" command and
not the other way round (like using "revBrowserExecuteScript")
my finding is that this works as expected.

As an aside I noticed that on Mac the performance
of JavaScript animations, which are pretty smooth
using the current revBrowser external, is extremely bad.
Hope this will change.

Apart from that I am really happy with
the move to a modern browser component.

Ralf

Performance issues with animations in iOS standalones built with version 5.5.2

[Ralf Bitter]

I am experiencing choppy animation using AnimationEngine 5
in iOS standalones built with version 5.5.2. If I build using
LiveCode version 5.5.1 and exactly the same stack, animations
are smooth.

So there must have something changed affecting object animation.
Could this be related to the reworked internal structure of the
engine? Did anybody notice similar behavior?

iOS: Setting defaultFolder seems to be broken - missing project folders in app package

[Ralf Bitter]

Whenever I build an iOS standalone with LiveCode 5.5.3 (Build 1497) all project
folders are missing in the app package, so for example referenced images are not
included. Furthermore I noticed that setting the defaultFolder strangely 
doesn't work
anymore with iOS builds. This applies to simulator tests too.

It only happens if I start a project from scratch. If I use older LiveCode files
created with previous versions of LiveCode all works as expected.

Anyone encountered similar behavior and has a recipe?

Re: iOS: Setting defaultFolder seems to be broken - missing project folders in app package

[Ralf Bitter]

Just to clarify:

setting the defaultFolder seemingly not working relates
to the fact that folders are not copied to the app package.
Of course, setting the defaultFolder to a nonexistent folder
does nothing.

So, the question is what could be the reason for missing
folders in iOS standalones?

Re: [CODE] cool elapsed function

[Ralf Bitter]

Hi Jacqueline,

may I invite you to check out the rigTimespan() function
in the date helper of revIgniter?
You would have to comment out the line "get rigLangLoadLang("date")"
and to replace all calls to rigLangLangLine() with whatever time labeling
you need.

Re: revIgniter - how to instal

[Ralf Bitter]

Hi Paolo,

it seems that you are using MacOS server. If this is the case
I am sorry. There is a bug (9869) in LiveCode Server confirmed by RunRev.
LiveCode server versions 4.6.3 up to 5.0.2 have two incorrect path environment
variables on Lion and Mountain Lion. These variables are:

$_SERVER["PATH_TRANSLATED"] and $_SERVER["PATH_INFO"].

As revIgniter is heavily dependent on path variables this means that
there is no way to run revIgniter using the said OS / server versions.

I reported this bug in November 2011. In September 27, 2012 I got the
following response from the RunRev QCC:

"your bug report has been addressed and the issue you raised is fixed.
We fixed this bug in release: 5.5.3-rc-1."

Unfortunately the fixed version is still waiting to be released.


Ralf

Recipe to play WMV on Win 7 with QuickTime installed

[Ralf Bitter]

Does anyone have a recipe on how to play WMV videos on Windows
systems with QuickTime installed?

For the live of me I don't get decent playback performance
using HD 720p H.264 QuickTime mov files on Windows (Win 7 in this
case). The stuttering is just unacceptable. MP4 AVC files play
even worse. All my test movies play fine in the QuickTime player
for Windows but not in a stack. Setting the player's "alwaysBuffer"
to false makes no difference.

So, I tried the same test video (same resolution, approximately the
same frame rate) as WMV2 and voilà, the performance is much better,
but there is another problem:
If QuickTime is installed the card's player object stays empty and
start player "myVideo" does nothing, at least in the IDE, even if
the stack includes nothing more than the player. And yes, "dontUseQT"
is set to true before any player or movie related action.

The only way I managed to make the video appear at all means was,
strange enough, to drag any object from the tools palette onto the
card containing the player while the property inspector was visible.
Of course this is no solution but it tells me that there must be a
way to force the player to show the source and therefore to start
playing a WMV in an environment I described above.
By the way, to do without QuickTime is no option as in my case I
need QuickTime to be installed. On the other hand, as I explained,
it seems that I am forced to choose .wmv over .mov.

Any suggestions? Anyone?

Re: how to play WMV videos on Windows

[Ralf Bitter]

Hi Claude,

thanks for the feedback. Tried what you suggested. Using revBrowser
and a Flash player HD 720p H.264 QuickTime mov files play fine even
the MP4 AVC ones. So, this means that I don't anymore need to find
out how to to play WMV on Windows systems with QuickTime installed.
Nonetheless it seemingly turns out that the player object is pretty
useless on Windows with QuickTime installed when it comes to playing
video, at least when there is a demand for decent quality.
Hopefully this will change in the near future.

Thanks again

Ralf

Re: how to play WMV videos on Windows

[Ralf Bitter]

Thanks Colin. Actually I asked for a recipe on how to play WMV videos
on Windows systems with QuickTime installed because of bad playback
performance of HD quality QuickTime movies. So, if WMV would have worked
using WMV would have been sort of a compromise. Claude's suggestion is
a solution, so I can happily set WMV aside as all my footage is MP4 AVC
anyway. Should have asked for a recipe on how to play high quality video
on windows with QuickTime installed.

Anyhow, I find the player object pretty frustrating and one should not
have to use Flash and revBrowser for a simple thing like playing video.


Thanks

Ralf

In the end, as a precaution, I will refuse any job in case video

Re: how to play WMV videos on Windows

[Ralf Bitter]

Hi Jacqueline,

the problem is that I have some interactive QuickTime movies which need
dontUseQT set to false but as soon as dontUseQT is set to false there seems
to be no way to play WMV files even if you set dontUseQT to true (of course
before any player or movie related action).

Re: RevIgniter & current on-rev LiveCode server version

[Ralf Bitter]

Hi Keith,

the bug mentioned in the user guide applies only to
installations on Lion and Mountain Lion. It is
fixed in LiveCode Server release: 6.0.0-rc-1 though.

This means, revIgniter should work on on-rev.com without
flaws. I would try to start with a clean root folder
without any Apache directives in .htaccess. Then all
you have to do (really) is to copy the files and folders
included to server root. Check your installation using
an URL like "yourSite.on-rev.com/index.lc".

If you don't move or rename any of these folders there is
no need to modify index.lc. The location of these folders
are relative to the directory where your index.lc is located
independent of how deep your revIgniter folder is nested.

In this case all you have to do (really) is to define the "Base Site URL"
in your configuration file like:

put "http://myDomain.com/myFolder/"; into gConfig["baseUrl"]

It is at the top of the configuration file in 
system/application/config/config.lc

Check your installation using an URL like:

http://myDomain.com/myFolder/index.lc


The next thing to do is to get rid of the need to include "index.lc" in your 
URIs.
This is explained in detail in the user guide.

This is definitely a reasonable question because:

The community version of LiveCode server prevents
using protected stacks.

The current commercial version is 5.0.2.
So, I, too, would like to know when the latest (6.0.2)
version of the server engine will be available
for those who have a commercial license.

5.0.2 is the current commercial version of the server engine.

Re: File uploading to on-rev.com account with revIgniter

[Ralf Bitter]

Hi Dave,

did a test on "odin" and the upload worked as expected.
On which server is your revIgniter installation?
Can you tell which version of ImageMagick is installed?

By the way, I just found a typo in the User Guide:

put 1024 into tConfig["MaxWidht"]

But the sample script should work anyway.

Using the upload library you don't have to deal with imageMagick at all.
The library does all relevant shell calls regarding imageMagick.

mergDocCanOpen opens iOS sharing menu

I have a LCB widget I used as a replacement

and the color of each object's border and dividing lines. The only way
around is scripting lines or whatever to be used as an overlay -- which is
a kludge. But is it possible using LCB to address individual parts and

should be detected. But it would be important, in my opinion, to allow each
and every graphical widget to detect mouseWithin, mouseMove, mouseDown,
mouseUp, mouseEnter, mouseLeave, etc.

Is there anybody working on such widgets and updating them to newer
versions? Is there a version history for each widget?

The documentary of the widget (widgets) in the Dictionary could be enhanced
with a first date of appearance and dates of new versions as well as
enhancement requests or planned enhancements? I assume the author is
LiveCode Ltd.?

Re: Trying to use the Segmented Control

Roland thanks, did what you proposed,
means I added two check boxes to toggle
the properties of the button group.

And please don't forget to send me your
button bar.

@ Ralf Bitter

Dear Ralf, I downloaded your segmented control from:
https://github.com/revig/universal-button-widget/releases/tag/1.0.1

and I installed the widget using the Extension Manager in the IDE.

It looks very nice. Exactly what allows control and even change the
behavior. First time users should know that the custom properties (as
described by you) are custom properties of the group "menuBtnGrp". For a
first time, two visible switches would probably allow users to just test
without having to look under the hood.

Since I must build such button groups dynamically (users can add or remove
modules which then appear put on the navigation bar that is constiung of
such "buttons") I will just need to script this a bit in more detail.

I also wrote my own bar using a table field where I mimic the hiliting and
hover (mouseover) effect when moving the mouse over lines or using arrow
keys (up and down. It looks like a button bar when using an image source
for a first character. But it does not work for SVG as far as I know. And
it only works for vertical "bars". On the other hand, it is very easy to
dynamically create and remove lines. Actually, I track the mousemove and
detect the line number and then place a transparent graphic over the
selected line. This gives more control than using the built-in hilited
property.  If someone is interested, I can send...

So, thanks a lot to you for providing this, and I am sure I will have fun
using it...

Roland

Hi David,

if you go the revIgniter route use rigGetHTTPheader("myCustomHeader"),
otherwise you can use $_SERVER["HTTP_myCustomHeader"].

Re: Call lc from php?

[Ralf Bitter via use-livecode]

Hi Richard,

I agree to your comments, especially to
the first paragraph ;)

Joking aside, regarding CMS, CRS, LMS etc.,
I was thinking about developing a CMS based on
revIgniter for quite some time, just for the sake
of increasing the diversity, but stayed away from
doing it because, if done right, it is such a huge
task and because it would not pay my bills.

Todd Fabacher once started to develop a revIgniter
based CMS but I have no idea if it was ever released.


Ralf

On 23.01.21 21:02, Richard Gaskin via use-livecode wrote:
revIgniter* is a wonderful framework, and one of most well-managed open 
source projects in our community.  Ralf has delivered a faithful 
re-envisioning of the popular WebIgniter framework for PHP, with some 
very savvy twists that make it a joy for LiveCode scripters.


But WebIgniter is far from PHP's only server framework, and I'd guess 
Ralf would agree that as valuable as revIgniter is, it isn't the only 
possible solution for every conceivable type of web site, app, or service.


Reproducing many well-established PHP packages in LC is more possible 
with frameworks like revIgniter than without.


But if the PHP package is sophisticated enough it'll be a lot of work.

And in many cases we're asked to extend systems we have no control over.

There are many good reasons to pursue integration with existing services 
rather than replacing the entire service from scratch.



With my interest in Nextcloud as a backend, for example, I could save a 
lot of time using revIgniter to build out self-signup. user permissions 
groups, password reset, WebDAV support, OAuth in both directions, 
headless REST, even federation, and an admin UI to manage it all. But 
with Nextcloud I get all that with one Snap command, so I can jump right 
into the client-side functionality which is my main interest on this 
project.


Similarly, some of my work these days has me integrating LC apps with 
popular CRMs - the good CRMs are very expensive to produce and not 
easily replicated, even with a great framework like revIgniter.



Like anything else in development, it's just another case of choosing 
the best tool for the task at hand.


For a wide range of projects, revIgniter is a perfect choice.

And when you need to integrate LC with an existing PHP system, we can do 
that too.




* For those of you who haven't seen Ralf's recent work on the revIgniter 
site, in addition to offering truly exemplary documentation I also 
appreciate the little touches he puts in, like the SVG intro animation 
for the top banner:

Re: Would anyone miss convertOctals?

[Ralf Bitter via use-livecode]

On 09.06.22 14:44, Mark Waddingham via use-livecode wrote:
So I'm currently sitting here about to embark on fixing 
 (which is the final 
thing to sort out before being able to merge my constant expression 
patch) and I was reminded of 'convertOctals'.


Now, generally, I am somewhat averse to actually removing any language 
feature (even those we have deprecated, unless we absolutely have to!) - 
however, I would really like to make convertOctals have no effect at all 
in 10.0+ as it adds a disproportionate amount of complexity compared to 
(what I think, at least) its utility is (particularly in the context of 
things 'coming next' like the script compiler).


So three questions:

   1) Do you know what convertOctals is, and what it does?


Yes




   2) If you do, have you ever actually used it in any scripts which are 
actually still in use?


Yes, revIgniter uses "convertOctals" and "umask" dealing with access 
permissions of files and folders.




   3) If you do use it in any scripts which are still in use, would you 
be willing to change them to not use it?


Sure, I would exchange them with carrots.



   4) If you do use/have used it, had you ever noticed that it has been 
slightly broken for years?


I have to admit, no.



Now, its always better to offer a carrot when there is a stick (or in 
this case, an axe) being wielded and the carrot in this case would be to 
expand the numeric literal syntax to add both explicit octal and binary 
number literals alongside hexadecimal:


     0xabcdef - hex literal
     0o777 - octal literal
     0b101110101

The key difference between 0o777 and using 0777 (with convertOctals 
true) is that the former is not ambiguous at parse time, it doesn't 
require a runtime property set to true in order for the engine to 
convert the string to a number correctly.


Please let me know your thoughts :)

Warmest Regards,

Mark.

P.S. In the scheme of 'breaking changes' - we've already made a number 
of them for 10 already, and my gut tells me removing convertOctals is 
likely to cause less consternation than those we already have - but I 
could be wrong!

Re: arrayencode

[Ralf Bitter via use-livecode]

Hi Alex,

the JSONtoArray() function is part of the mergJSON external.
The README of this external describes how to use this function
and it's counterpart JSONtoArray as follows:


This external has been implemented to encode/decode UTF8 JSON to a LiveCode 
array as quickly as possible. Currently externals can not work with 
multi-dimensional LiveCode arrays so the intention is it is used with two 
functions like this:

-- pArray - array to be encoded
-- pForceRootType - can force the root to be an object if it looks like 
an array
-- pPretty - include whitespace
function ArrayToJSON pArray,pForceRootType,pPretty
   repeat for each key tKey in pArray
  if pArray[tKey] is an array then
 put "}"&ArrayToJSON(pArray[tKey]) into pArray[tKey]
  end if
   end repeat
   return(mergJSONEncode("pArray",pForceRootType,pPretty))
end ArrayToJSON

function JSONToArray pJSON
   local tArray,tKeys
   repeat for each line tKey in mergJSONDecode(pJSON,"tArray")
  put JSONToArray(tArray[tKey]) into tArray[tKey]
   end repeat
   return tArray
end JSONToArray

For most cases the above is all the documentaion you will need. There are 
however some quirks to the external you might need to know about.



Another option would be to load the JSON extension and to use
the JsonImport() function.

Thanks Ralf. I did see that code in the dictionary - but it also says

thews.goulding.script-library.mergjson library, so (I think) I shouldn't 
need to put them in myself.


In fact, I did try it anyway - but that simply changes the error to 
"handler not found: mergJSONDecode"



Hi Alex, have you added the mergJSON External to your server 
installation? I have just tested this again, actually it should work.

My LC Server version is 9.6.6.





Another option would be to load the JSON extension and to use
the JsonImport() function.

Didn't know about jsonImport; it's not mentioned in the dictionary, but 
I now see it shows up in a few lessons, etc.


However,I think the real problem for me is "... to load the JSON 
extension ...". I wasn't aware I had to load those extensions which are 
already part of the standard package (maybe I did that years ago and 
have had time to forget :-).


I can't find anything about loading extensions other than what to do in 
the IDE.


How do you load extensions to LC Server ?  On a shared web provider ? 
(on-rev)


You guessed it, use "load extension", example (tested on on-rev):

load extension from file 
"/home/rabit/public_html/ritest/application/extensions/com.livecode.library.json/module.lcm"

Crash on launching LC server version > 9.6.7 using terminal

[Ralf Bitter via use-livecode]

Hi all,

have any of you ever experienced that a version of LC Server
newer than 9.6.7 crashes on launching using hashbangs?
This is the case for me on a MacBook Pro M1 running
macOS Monterey 12.6.

I suspect this is related to incorrect code signing, as the
crash report shows that the kernel sends the exception
"Exception Type: EXC_BAD_ACCESS (SIGKILL (Code Signature Invalid))".

Unsigned LC versions (LC server version < 9.6.8) are not affected.

It would be nice if someone had a recipe to solve the issue.

Hi Mark,

thanks very much for taking the time. I made a note
of your comment at the time but did not catch stam's
subsequent comments (regarding the codesignature of
server dylib files).

Your instructions helped partially, as launching
LC server from the terminal did not crash the executable,
but using hashbangs still killed LC server. I will apply
the cp/rm/mv dance to all included dylib files and will
report if that solves the problem.

But now I want to produce html documents including Chinese characters encoded with utf-8, 
using LC Server to output an .lc file to publish on the web. I had naively thought that 
putting in the “” header at the top would do it, but no, LC 
Server apparently serves up html with charset=ISO-8859-1 (the native encoding) declared by 
default, and that overrides the header in the .lc file. The encoding declared was checked 
using "Rex Swains HTTP Viewer”. I am reasonably confident the actual content of the 
file is correct utf-8, since the Chinese glyphs are rendered as garbage ISO-Latin 
characters not as 

The next step was adding a line such as

AddCharset UTF-8 .lc

to .htaccess. No help. I note that other web pages on the server are created by 
WordPress, and they have the charset=utf-8 declared.

I presume I am ignorant of some environment setting which controls what 
HTTPHeader is declared in the output from LCServer? The obvious choice “the 
HTTPHeaders” but that is not the answer it seems.

[I know I can get individual unicode characters to render using html escapes such 
as &x2304; even when the  page is declared with a non-unicode encoding, but 
that is not a viable solution here.]

Re: Encoding in LC server - the final piece of the puzzle

[Ralf Bitter via use-livecode]

Neville, you need to send the header
before outputting anything else.
So, this means your LC server script
should send the header and then the HTML data.

That sounds exactly like the incantation I needed.

But I can’t get it to work.

The first 3 lines of my webPage.lc  file are





(Not sure that 3rd line is necessary with HTML5, but presumably it couldn’t 
hurt)

The header suggested just seems to be ignored when LC Server sends the output 
to Apache.  (Tried it with “put new header…” too after I found some 
documentation for the magic spell.)

The default setting for Apache on Dreamhost is naturally the native encoding 
ISO-8859-1.(Is there any way to override that with htaccess, since all my 
WordPress pages are served as utf-8 already?)

Hello all,

Recently I decided to try out a number of different button styles to see which ones 
I liked best, and I ran across some odd behaviour with “Universal” buttons. First, 
there does not appear to be any style difference between an enabled universal button 
and a disabled one. With all other button styles there is a noticeable difference 
between the enabled and disabled versions. More importantly (perhaps) with all other 
button types if you depress the mouse over the button then move the mouse off the 
button and release it it does not fire the button. With universal buttons if you 
move a depressed mouse off the button and then release it the button fires. And this 
behaviour does not appear to conform to Apple’s user interface guidelines "The 
mousedown event is fired at an Element when a pointing device button is pressed 
while the pointer is inside the element.”

Are these differences in the Universal button deliberate features or bugs? If 
features, why so?

Thanks
Mark

Re: LiveCode server as OAuth2 client for APIs?

[Ralf Bitter via use-livecode]

Hi Keith,

using revIgniter you can always hard code the opening
form tag, this way you can use any URL as an action
attribute.

However, your message has prompted me to change the
rigFormOpen() function so that you can override the
current URL with the value of an optional action
attribute included in the second parameter.
So, if you like, you can download the modified
version of the form helper at:

Any advice greatly appreciated.

Hi Ralf,
Thanks for the guidance and updated formHelper script - and apologies to folks 
not using LiveCode Server or RevIgniter - I now realise this should have been 
posted on the use RevIgniter list.

I’ve now got a basic button that submits a form data post to the Salesforce 
authorisation server. However, there are a couple of issues, which are probably 
due to me misreading the user guide (again!) and/or getting confused over what 
markup goes into controller and view files for RevIgniter.

I’m using a controller file to prepare and add to the gData[] array both the 
form contents and submit button, which are then accessed in the view file, 
using the following...



In the controller file, I first used the recipe for ‘Adding Hidden Input 
Fields’ to create an array for the third ‘hidden’ parameter of the 
rigFormOpen() function. This worked as a POST but all the hidden fields are 
visible in the view file’s html. This is rather insecure for authentication, 
revealing consumer_id (and in future, client_secret, which I’ll need to add to 
increase security once basic access is proven).

So, I’m hoping the rigFormHidden(tData) recipe can keep the hidden content 
‘LiveCode-side' until post submission and out of the HTML. So far the hidden 
values don’t seem to be getting into the POST, as I’m getting an unsupported 
request type (so the ‘response_type=code’ is not being received).

I’m sure I am taking the wrong approach, as well as incorrect syntax in my 
controller handler - as if I understand things correctly, the way I’ve got 
parameter three of the rigFormOpen() call pointing at gData[‘hidden’] would, if 
successful, render the hidden contents visible in the view file’s html...

   # Prepare Salesforce login form
   
 # Load form helper library

 rigLoadHelper "form"
   
   # Prepare hidden parameter data array

 put “XXsomeClientIdXX" into aHidden["client_id"]
 put URLencode(“XXsomeRedirectURLXX") into aHidden["redirect_uri"]
 put "code" into aHidden["response_type"]
 put rigFormHidden(aHidden) into gData["hidden"]
 
 # Prepare form

 put rigFormOpen(“XXauthoirisationServerURLXX", “", gData["hidden"]) into 
gData["formOpen"]
 
 # Prepare submit button

 put "sfLoginBtn" into aData["name"]
 put "sfLoginBtn" into aData["id"]
 put "btn btn-primary" into aData["class"]
 put "submit" into aData["type"]
 put "Salesforce Login" into aData["value"]
 
 put rigSubmitButton(aData) into gData["submit"]
   
   # put "Topic1,Topic2,Topic3" into gData["ListItems"]


   get rigLoadView("homeMainView")

I’m probably making multiple newbie errors, but I’ve been unable to find any 
worked examples of RevIgniter controller and view file markup for form posting. 
So, I’d be obliged for any hints and tips.
Best,
Keith

Re: Is anyone using tsNet external with LCserver?

[Ralf Bitter via use-livecode]

Be aware of these issues
- Using tsNetGet() on LC server to request a files list
from a FTP server returns nothing, so tsNetRetrData() is empty.

http://quality.livecode.com/show_bug.cgi?id=18961

related, but didn't write a separate report:
- Using tsNetSendCmd() on LC server to send an asynchronous
command to a FTP server returns empty without executing
the command.

And don't expect to get access to the extended feature set
of tsNet Business on LC server. Seems there is no way to activate
a business license for tsNet on server, don’t think this has changed.
For what it’s worth, this and the issues mentioned above are
the reasons why my half-finished revIgniter FTP library is waiting
on the shelf since about one year.

Re: Is anyone using tsNet external with LCserver?

Hi Panos,

I know that tsNetVersion() yielding an error is fixed.

But does this really mean that all  tsNet Business
features are enabled on LC server (business)?

Just did tests (got my files from the shelf) using
as an example asynchronous requests, which failed.
Synchronous flavours worked as expected.

mergDoc - no preview, no sharing

[Ralf Bitter via use-livecode]

Is there anybody who can confirm that the iOS external
mergDoc plays nicely in an iOS 11.2 or iOS 11.3.1 environment?

I am particularly interested to know if handler mergDocShowPreview
and “Copy to …” share extensions using mergDocShowOpenInMenu
or the share button work.

My tests using the mergDoc.livecode demo in LC 9.0 as well as in LC 8.1.10
produced the following results so far:

Files tested: .docx, ppsx, .txt, .pages, .pdf, .png

Device: iOS 11.2 on iPad Pro 10.5 inch

mergDocShowPreview worked for .png files only
“Copy to …” share extensions using mergDocShowOpenInMenu
or the share button fails although mergDocCanOpen() returns true,
the modal just shows the file name and “Office Open XML show” for
.ppsx files as an example

Simulator: iOS 11.2 on iPad Pro 10.5 inch

mergDocShowPreview works for all files
“Copy to …” share extensions using mergDocShowOpenInMenu
or the share button can not be tested


Device: iOS 11.3.1 on iPad Air

mergDocShowPreview works for all files
“Copy to …” share extensions using mergDocShowOpenInMenu
or the share button fails although mergDocCanOpen() returns true,
the modal just shows the file name and “Office Open XML show” for
.ppsx files as an example
