[Pharo-project] 1.3 and scamper html package; unexpected emergency evaluator
by Schwab,Wilhelm K Oct. 15, 2011

Oct. 15, 2011

Stef, all, I am doing some well-intentioned reverse-engineering of a system (aka trying to read uncommented code) and have been looking at some html that it produces. Scamper's parser was helpful some years back, so I looked on SqueakSource and found two HTML packages. I had the validation package installed, so I decided to add the scamper parser package. Weirdness #1: I was curious about what was going to happen when I installed a second HTML* package. I did NOT expect the existing package(s) to be replaced :( Didn't save that image. I owe you guys some serious testing on 1.3, so I decided to use the one-click to run the scamper package. My plan was to view source on a locally-produced page, select-all+copy and then pull the text from the clipboard to parse it. I *should* have done this: HtmlParser parse:Clipboard default clipboardText string readStream. Aside from every other item being an empty HtmlAttributes (probably very correct if a little odd looking), it does pretty much exactly what I had in mind. I said I should have done the above. What I in fact did was HtmlParser parse:Clipboard default clipboardText string readStream. (the #string send is missing). Weirdness #2: It's interesting, because I get a vm error (text all over the main window with an offer to open an emergency evaluator) saying *** System error handling failed ***. Hitting any key clears the error and displays a walkback that will open a debugger revealing that #replaceHtmlCharRefs is missing, or so that appears to be the problem. Of course the real problem is that I evaluated the wrong expression, but I should simply get the walkback, not the callstack. Is there something I can do to help unravel the cause of the problem? I used the 1.3 one-click from the web site. Bill

[Pharo-project] MCDirectoryRepository defaultDirectoryName ignored?
by Mariano Martinez Peck Oct. 15, 2011

Oct. 15, 2011

Hi guys. I have changed the value of MCDirectoryRepository defaultDirectoryName by doing MCDirectoryRepository defaultDirectoryName: '/Users/mariano/Pharo/localRepo/'. or by the settings browser...but anyway, it seems "ignored". For example, if I now create a new repository in the monticello browser, and I download a package, the package cache used is the previous/original one (there the .image is). I want to set an specific package-cache and that all projects/packages loaded in the future take that package cache. any ideas? thanks -- Mariano http://marianopeck.wordpress.com

[Pharo-project] [ANN] Fuel release version 1.7
by Martin Dias Oct. 15, 2011

Oct. 15, 2011

Hi folks! We have released the new version 1.7 of Fuel, a binary serialization framework for Pharo that provides extremely fast deserialization. More information on our home page<http://rmod.lille.inria.fr/web/pier/software/Fuel>. Again, I thank ESUG for sponsoring me through the SummerTalk<http://www.esug.org/wiki/pier/Promotion/SummerTalk/SummerTalk2011> program. You can download this version in Pharo 1.2.1 or 1.3 with: Gofer new squeaksource: 'Fuel'; package: 'ConfigurationOfFuel'; load. ((Smalltalk at: #ConfigurationOfFuel) project version: '1.7') load. The list of changes includes performance optimizations, design clean-ups, and new features. - The FLSerializer and FLMaterializer API has changed. They are no longer implementing the algorithms but are a kind of FaÃ§ade. - Developer guides with examples: Getting Started<http://rmod.lille.inria.fr/web/pier/software/Fuel/Version1.7/StreamsGuide>and Customizing the graph<http://rmod.lille.inria.fr/web/pier/software/Fuel/Version1.7/Hooks> . - Serialization substitutions: "Store this object instead of me." - Global sends: "Restore me by sending this selector to this global" - Versioning the stream: We prefix the stream with a version number that should match when loading. - Performance optimizations on instances of: -- Word-like classes. (We thank a lot to Henrik Sperre Johansen for your help!) -- ByteString and Symbol. -- Date, Time, Duration and DateAndTime. -- Point and Rectangle. -- MethodDictionary. Now materialization is 2000x faster, thanks to its new rehash without become. - Huge clean-up in Tests package. Cheers! MartÃn Dias

[Pharo-project] Any serializer can customize serialization strategy?
by HernÃ¡n Morales Durand Oct. 15, 2011

Oct. 15, 2011

Is there any serializer (Fuel/StOMP/Ma object serialization/BOSS/SRP/SIXX??) which let me attach an external compressor/decompressor for specific Strings to the serialization/deserialization process? With external I mean it could be in a separate binary (I could arrange the binding though). Thanks HernÃ¡n

Hi guys apparently people get excited by nodeJS and I would like to know the equivalence of var http = require('http'); http.createServer(function (req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); res .end('Hello World\n'); }).listen(1337, "127.0.0.1"); console.log('Server running at http://127.0.0.1:1337/'); To run the server, put the code into a file example.js and execute it with the node program: % node example.js Server running at http://127.0.0.1:1337/ Here is an example of a simple TCP server which listens on port 1337 and echoes whatever you send it: var net = require('net'); var server = net.createServer(function (socket) { socket.write("Echo server\r\n"); socket.pipe(socket); }); server.listen(1337, "127.0.0.1"); we should communicate better :) Stef

[Pharo-project] socket.io
by Herby VojÄÃk Oct. 14, 2011

Oct. 14, 2011

Is there / planning a socket.io (server) support in Pharo? I am making suite of client-server application where I strongly consider socket.io as the communication layer; there is no problem with clients, but at the server-side, socket.io seems only to be supported by its native node.js (which is not bad, but I'd like to consider Smalltalks as well, Pharo being the first choice). Thanx, Herby p.s. If you get this message second time, I am sorry, I got confused by the Nabble's messages. -- View this message in context: http://forum.world.st/socket-io-tp3891592p3891592.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
