You’re welcome. One thing I forgot to mention - you need to have LC 9.0.5
or 9.5 installed to test the Pocketsphinx example. A bug was fixed related
to passing null to variadic expressions.

For those interested you can find the source code for the projects we

pocketsphinx project is an experiment to get it working and teach some

I was reading the RabbitMQ page on the MQTT plugin earlier:
https://rabbitmq.com/mqtt.html

That page says you have to manually enable the plugin in order for it to
work. Once it is enabled there is no reason Mosquitto wouldn't work with
it. They both support MQTT 3.

There is also a RabbitMQ C library that provides support for AMQP. It is
available here:

https://github.com/alanxz/rabbitmq-c

And this page seems to have some information on using it:

https://www.cloudamqp.com/docs/c.html

I haven't looked over the source code to see how easy it would be to wrap
in LCB though.

I decided to look into this further and I eventually found libMosquitto. It
is a C library with an API that that could be wrapped with FFI without too
much trouble (no structs within structs that I had to deal with). With Mark

Hi Trevor.
I know that is a bit late and that I will not be able to attend anyhow (sigh).

I would love to see how to implement the Flic Bluetooth button library  
(www.flic.io ).
It is a small battery powered button that interact with iOS, Desktop and 
Android (1 click, 2 click, hold click)

Libraries are available for Swift, ObjC and C++ here, with working xCode 
example:

Re: Question for LCB FFI workshop attendees at upcoming conference

[Lagi Pittas via use-livecode]

Hi,

It will be sad, a great loss or even a travesty if the worshops are not
recordered somehow.

Even if by using a couple of mobile phones for good sound and "so so" video.

The simulcast won'rt be anywhere near as useful as it could be without
these Workshops.

If the slides,text, resources  etc ultimately become available that could
go someway towards mitigating the situation,
and not waste of all that programming wisdom by limiting it's access to the
wider community.

We still haven't got our 2000 widgets after nearly 4 years, and  I will let
others decide why this is - I have my own opinions.

Any Workshops -  whether Monty's, Marks Ali's or yours -  should be
recorded (I hope people in the audience don't have their phones confiscated
for making "bootleg" copies).

If LC wants an extra pound of flesh then so be it - but "Say it ain't so".

My 2 Pence worth

Wow! Thank you Trevor!

I have slowly (far too slowly) been trying to develop my LCB expertise 
to wrap Sphinx, but the C side of things (building the DLLs and where to 
place them was stumping me). I am pretty sure, with the files in the 
right places and the minimal interface working, I can add functionality 
to a Pocket Sphinx library widget.

Thanks for the suggestion Paul. This ended up being a really good example
to work on.

I was hoping to just grab the precompiled DLL for it but the downloadable
version has a bug in it and would just exit whenever I tried to use it.
With Mark Waddingham's help (a lot of it) I now have a basic version
working on both macOS and Windows. Even the macOS version required some
interesting steps so that the dylibs (pocketsphinx and sphinxbase) would
only load the dylibs in the extension's code folder. Wrapping the code was
also an educational experience and has a number of teaching points that I
will bring up in the workshop.

For those of you who offered up other suggestions - I took a look at the
pages you sent but I didn't see any obvious C interfaces and they also look
like much more involved projects. FFI will not work with C++ right now.

I'm not there, but what would be fantastic is to get TUIO running in 
Livecode.


https://www.tuio.org/?software

It's the most used protocol on big touch screens which are used in 
Offices, Hospitals, big companies, Workshops, Board meetings etcetera


There are even screens now with integarted Windows PC's and even with 
integrated Android which use this protocol.


On the TUIO site many program languages are supported, but not LC.

I’m not really sure if the aggregate type is intended to be a stopgap solution 
so perhaps if it is that may be a good reason not to spend too much time 
handling cases like this and figuring out how best to handle unions etc. You 
can do what you need to do it’s just not a huge amount of fun when dealing with 
complex structs.

Ideally we would have a foreign record type where you could specify member 
names and there would be syntax to support unions so they aren't so tricky to 
handle and the engine can figure out padding if union members are different 
sizes etc.

I'd prefer 1024h, but I'm good with either. I've rant^H^H^Hsuggested 
this several times, but it hasn't gone anywhere.




FWIW my talk which is on directly before Trevor’s workshop will be a whirlwind 
tour of LCB FFI so that anybody that feels they want a refresher/primer before 
entering the workshop can get one.


Cool. But  it's opposite Ali's can't-miss morning talk. I need 
two of me... good thing these are getting recorded for later.

Yes it would probably be helpful to be able to write `h1024` and have it 
convert to and from a CArray type which could have an element type property (in 
this case UInt8) and a length property (1024) and bridge to a list of the 
element type and syntax to move to and from Data if necessary.

FWIW my talk which is on directly before Trevor’s workshop will be a whirlwind 
tour of LCB FFI so that anybody that feels they want a refresher/primer before 
entering the workshop can get one.

Cheers

I haven’t had to wrap code that used such a beast so I haven’t investigated
other approaches myself.

Heh. Right, I was just hoping you had another way of dealing with this.

From a current LC offer:

"Livestreaming includes track 1, track 2 and the LiveCloud workshop.
Other workshops are not recorded or streamed."

So the (most interesting) FFI workshop is *sadly* not even recorded.

I would love to see a sample LCB wrapper for PocketSphinx!

https://cmusphinx.github.io/wiki/tutorialpocketsphinx




I should have added, even just the minimal of a LCB library where I can 
write a script like:


on mouseUp
  ask file "Please select a WAV audio file to convert to text:" with 
type "WAV Audio FIle|wav|WAVE"

  if it is empty then exit mouseUp
  put sphinxTranscribe(it) into fld "Text"
end mouseUp

where sphinxTranscribe takes a WAV file and used PocketSphinx to return 
the transcribed text of the audio using the default settings.


Just that bit would be a boost t getting into further LCB development 
around pocketSphinx.

I will be introducing them but I can’t fix limitations of the engine.

Are you going to be covering foreign aggregate types? For me that's the 
brick wall I run into when attempting to use LCB to access APIs. I have 
yet to run into a case where I don't need to access an embedded buffer 
in a C struct. If it's an 8-byte buffer, I can use


public foreign type tType binds to "CType:"

but when I need a 1024-byte buffer,

"CType:"

is just too unreadable, unmaintainable, and error-prone to deal with.

I don’t know the answer to that. I’m not sure what is being broadcast and
what isn’t.

Trevor,

Are the workshops also available through Simulcast or are they "offline"?
Would be great even if only watching would be possible w/o interaction, but i 
am afraid they aren´t, right?

Question for LCB FFI workshop attendees at upcoming conference

[Trevor DeVore via use-livecode]

This is for anyone who plans on attending my workshop on using FFI in LCB
at the conference. Is there any code (a macOS Framework, Windows API, DLL,
dylib, etc.) that is written in Objective-C or that has a C wrapper that
you are interested in wrapping with LCB in order to make it available to
LiveCode?

If so, let me know in a response to this thread and I can take a look at it
before the workshop to see if I can include it.
