SourceCodeTourGuide updated!

by HwaJong Oh

SourceCodeTourGuide has improved. - loading TGCamp subclass you created to store contents has become easier. A "choose" dialog popups with list of subclasses of TGCamp. - all of thinkable New/Save/Load logic is implemented. (e.g. Ask to save when you close a window if there is unsaved change.) Guaranteed to work on Pharo 1.4 summer. (supporting Pharo 2.0 and Nautilus is about to come) Installation code is wiki of http://www.squeaksource.com/DaliotsPlayground.html Gofer new squeaksource: 'DaliotsPlayground'; package: 'ConfigurationOfDaliotsPlayground'; load. ConfigurationOfDaliotsPlayground project versions last load: 'SourceCodeTourGuide'. Any feedback is appreciated. Do not hestitate.

Re: [Pharo-users] OAuth and Twitter

by Janko MivÅ¡ek

Hi Adrian, Try with latest Pharo 1.4 OneClick which has SSL plugin included so that you won't need tuneling but use SSL directly with Zodiak. Cloudfork SSO works that way too.

OAuth and Twitter

by Adrian Fernandez

Hello All, I'm trying to get working the example shown in: http://blog.doit.st/2011/02/23/cloudforksso-on-pharo-with-stunnel/ I loaded the package without probles doing 1 Gofer new 2 squeaksource: 'Cloudfork'; 3 package: 'ConfigurationOfCloudforkSSO'; 4 load. 5 (Smalltalk at: #ConfigurationOfCloudforkSSO) project latestVersion load: 'Tests' When I try to evaluate the piece of code that follows, 1 self default httpClient: ((CFHttpClientTunnelAccess new) 2 client: CFHttpClientZincAccess new ; 3 tunnel: 'www.google.com' through: 'localhost:20011' ; 4 tunnel: 'api.twitter.com' through: 'localhost:20012'; 5 tunnel: 'graph.facebook.com' through:'localhost:20013' ; 6 tunnel: 'open.login.yahooapis.com' through:'localhost:20014' ; 7 tunnel: 'openid.hyves-api.nl' through:'localhost:20015' ; 8 yourself ) I found CFHttpClientTunnelAccess class is not in my image. Browsing, I found CFTunneledHttpClient, but the protocol of this class is different from the missing one. Furthermore, I don't understand where this code should be located, so that self reference makes sense. I'm using Pharo 1.3 , as I think it is the Pharo version contemporary with this package and post. Is there some updated documentation for this? is someone using this package or connecting to twitter from pharo? Thanks af

The primitives are in AioPlugin (http://www.squeaksource.com/AioPlugin/) which connects to the low level select() implementation that Ian Piumarta developed for the unix VMs. I think that this works on Mac and on Cog VMs also if the plugin is provided (but it will not work on Windows). Note that the socket that you use in the image may already be using select() to respond to incoming data. HTH, Dave

You could experiment with #isDataAvailable and/or very short timeouts to service more connections with one thread, but that won't be easy (you would be at the mercy of the primitives with their subtle platform differences). -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

Polling sockets

by Santiago Bragagnolo

Hi guys, theres something like the select or poll C functions in order to wait for incoming-data from a set of sockets? I searched at the list and in the pharo by example book without any success and i didn't find a method named poll / select ( select in terms of sockets ) in the image. Maybe i need to spawn a process per socket? Thanks!
