>From Pharo, fork a shell to run something like âenv > /top/emphatic.txtâ. Or capture studio in Pharo, instead of writing to a temp file. It could be that a forkâed shell has a different environment than used by FFI. In that case the env vars may already be available through methods in the image. For the env that runs Bonjour successfully, run the âenvâ somewhere in the script that starts that server. Again, it is possible to have different environments, but most likely the environment is inherited, so is the same.

Re: MIDI Interface?

by Stewart MacLean

Hi Santiago, Thanks for this. My primary interest at the moment is interfacing with Midi. The sound stuff looks interesting, even if it is not quite my cup of tea music wise :) How far has your student got with the PortMidi bindings? As a first step, as I can get a precompiled library via homebrew I thought I'd start by migrating my VisualWorks PortMidi bindings - are they able to share this to get me started? I have built a Midi Access Layer (in VisualWorks) which layers over both RtMidi and PortMidi, which I had working on Windows quite a while ago. This maybe useful?

One thing I usually try in these situations is to dump the environment variables, then sort and compare for clues as to why one way works but not the other.

For our May meeting, Object Guild's Jonathan van Alteren and Erik Stel will give us a preview of Expressive Systems. Expressive Systems is a framework inspired by Richard Pawson's work on Naked Objects ( https://en.wikipedia.org/wiki/Naked_objects ). It allows Object Guild to rapidly develop flexible applications by focusing on the design of behaviorally complete objects in the business domain. By using a novel web application architecture based on CodeParadise ( https://github.com/ErikOnBike/CodeParadise ), it allows direct manipulation of business objects by the user. The goal of the framework is to better support problem solving activities and to empower users by giving them a first-person experience. The framework is currently in a (private) alpha phase of development. There are plans to open source the framework in the future. Jonathan has been developing business applications for various Dutch companies since 2001, in roles varying from programmer to solution architect. In 2018, he got hooked on Pharo/Smalltalk and never looked back. Erik has developed both technical as well as business applications in a variety of areas using a broad range of technologies. Heâs been a Smalltalk addict since using VisualAge in the late 1990âs. This will be a hybrid meetup where we'll connect to Zoom from the The City Pride pub ( https://goo.gl/maps/gxiuohY8z5CvA7wr5 ). If you'd like to join us either via Zoom or in person, please sign up on the Meetup page ( https://www.meetup.com/UKSTUG/events/285546604/ ).

Books

by danhunfeldz＠mail.com

I am learning Pharo and like to have printed copies of books. I see that âPharo 9 by Exampleâ has been released and it shows âGet printed (soon)" When will that be available on lulu to purchase? Also there is another book titled âPharo with Styleâ and there are two links to buy a printed version, but both sites are in French. Will this book be available for purchase on lulu at some point? Thanks!

Bonjour Service Discovery App available, and FFI library interface help required!

by Stewart MacLean

Ok, after bashing my head against the Spinning Wheel of Death for ages trying to use FFI to interface to the Bonjour service discovery library, I've done it another way using essentially the same design framework, but scraping the command line output from dns-sd with the help of OSSubProcess.

Re: PharoJs with JQuery/JQuery-ui

by Noury Bouraqadi

Hi, PharoJS exports vanilla JS. There is no support for JQuery. Having said that, PharoJS allow writing Pharo code with references to JS globals. So, you can directly use JS APIs. window addEventListener: #load block: [ window alert: 'Done Loading!!'. console log: 'PharoJS signals end of loading'] Noury On May 6 2022, at 5:30 pm, voxkmp(a)gmail.com wrote: > Hi - > > Can anyone give an example of how to use Jquery-ui in PharoJs? > I would like to use PharoJs to generate a page with a jquery-ui Slider widget and process its events through its slide function. > To give an illustration - what is the PharoJs equivalent to this javascript (in the $(document).ready function)? > $( "#slider" ).slider( { range: false, min: 90, max: 290, value:100, > slide: function( event, ui ) { > $( "#gradeECF" ).html("ECF:" + ui.value); > $( "#gradeElo" ).html( "Elo: " + (ui.value*7.5 + 700));} > } > ); > Thanks in advance for any help
