[Pharo-users] Slots vs collections

[N. Bouraqadi]

Hi,

Suppose I have an instance variable referencing a collection of booleans.
I want to have all elements of the collection be stored as bits. 
Is there a way I can express it using slots?

This idea can be generalized to other types of slots.

Re: [Pharo-users] Clean up method like #exiting from VAST

[N. Bouraqadi]

Hi Vince,

In Pharo there is startup list that is used also when quitting (in reverse upon 
shutdown).

To register a class :
Smalltalk addToStartUpList: aClass

The class startup behavior should go in class method
startUp: resumingBoolean

The class quit behavior should go in a class method
shutDown: quittingBoolean

Re: [Pharo-users] Anything on Pharo that would be like Opentalk on VW?

[N. Bouraqadi]

Sang did something similar a while ago too.
https://github.com/lxsang/SystemProcess 


It allows an image to launch workers. One thing interesting is that they share 
virtual memory, so they can exchange data during the execution

[Pharo-users] OneClick image

[N. Bouraqadi]

Hi,

Few years ago, there was a zip file called 'oneclick' that included everything 
to run Pharo on all 3 major OSes. All one had to do is unzip it, and launch a 
script that opens the image. 

What happen to that? Any idea why it isn't generated anymore?

[Pharo-users] How to load a single package in a Metacello baseline

[N. Bouraqadi]

Hi,

 I'm updating the the baseline of PharoJS to use the zinc websockets from the 
github repo https://github.com/svenvc/zinc.  I want to load package 
Zinc-WebSocket-Core.  So, in BaselineOfPharoJS>>#baseline: I've defined 
spec baseline: 'ZincHTTPComponents' with: [
spec
loads: #('Zinc-WebSocket-Core');
repository: 'github://svenvc/zinc' ].

However, for some reason I get Zinc-WebSocket-Tests loaded. Any hint how to 
avoid it?(edited)
Looking at BaselineOfZincHTTPComponents>>#baseline:, package WebSocket-Core 
does not seem to depend on tests 
spec package: 'Zinc-WebSocket-Core' with: [ spec requires: 'Zinc-HTTP' ]

Thanks,
Noury

Re: [Pharo-users] How to LAN feature

[N. Bouraqadi]

Hi,

Just want to point that I did some work late 2017 on UDP sockets including 
multicast and broadcast. 
The package named 'NetworkExtras' is part of the ReusableBricks repo of my team.
http://smalltalkhub.com/#!/~CAR/ReusableBricks
It has some dependencies on other packages.

I tested it in Pharo 6, but not 7.

PS. Since I can't keep up with the mailing-list traffic, don't forget to keep
