[Pharo-project] little challenge for sven and us
by StÃ©phane Ducasse Oct. 14, 2011

Oct. 14, 2011

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] how to capture pasting in a textmorph
by Tudor Girba Oct. 4, 2011

Oct. 4, 2011

Hi, I have a PluggableTextMorph, and I would like to get notified every time the text contents change. Currently, I intercept keystroke:from:, but the problem is that this does not capture pasting of text. Is there a better hook? Cheers, Doru -- www.tudorgirba.com "Value is always contextual."

[Pharo-project] looking for Kent Beck, in his roll of MongoTalk creator/admin
by Esteban Lorenzano Oct. 4, 2011

Oct. 4, 2011

Hi, Well... I modified somethings in MongoTalk package, in order to make it work in my project (for instance "update" command was missing)... and maybe, as my project continues growing, some more changes will be needed. I would like to commit the changes in the MongoTalk repository, but then I realized I have no rights to write in the repository... also, I noticed there is no license information provided (dumb me, I assumed it was MIT) and I need to know it before I can deliver my project :) So, I'm would like to define a couple of things: 1) license information (it would be really cool if it is MIT ;)) 2) write permission, if it is ok I to commit my changes there (a global Read/Write would also be cool, but not everybody âincluding meâ likes it everytime :) ) thanks, Esteban

[Pharo-project] MC load vs merge
by Camillo Bruni Oct. 1, 2011

Oct. 1, 2011

Hi everyone, I am improving the way the Monticello UI handles conflicts when doing a load. Right now you just get a warning which lets you decide whether to overwrite the local changes or simply cancel the action â a merge action is missing! I added the marge behavior, so far so good, but there is a slight glitch: The conflict message is shown based on conflicts on the package level, for performance reasons. Lets assume that the loaded version only contains new classes for the package that you changed locally, you still get a conflict message although the changes can be loaded without problems. So my question is on how to load stuff in this case: - go the git/svn way and load everything if there are no conflicts - load everything if there are only added entities (not removals/modifications) - always show the merge/diff view to check what changed manually cami

[Pharo-project] SystemReporter for Pharo [WAS] Fwd: [update 1.4] #14177
by Mariano Martinez Peck Sept. 30, 2011

Sept. 30, 2011

Hi guys. This is a small tool done by Alexander LazareviÄ to get information from the system. Very useful when reporting bugs. So keep it in mind. You can do SystemReporter open. or directly open it from the menu System -> SystemReporter. Alexandre: we found an implemented message #environ in: reportOSEnvironment: aStream | env | self header: 'Operating System Environment' on: aStream. env := [Smalltalk os environ] on: Error do: [^self]. env keys asSortedCollection do: [:name | aStream nextPutAll: name; nextPut: $=; nextPutAll: (env at: name); cr] so...it seems broken.

[Pharo-project] Why do I need a #removeAllObsoleteSubclasses in to garbage collect?
by Mariano Martinez Peck Sept. 30, 2011

Sept. 30, 2011

Hi guys. I have a simple scenario where I create classes and then I remove them. I just want to be sure the amount of metaclasses and Class subclasses is correct. Hence, I have the following test. What I don't understand is that the test only works when I do a #removeAllObsoleteSubclasses to all classes. Soâ¦my questions is, is that correct? I am doing something wrong? because I would expect that #removeFromSystem takes care about thatâ¦ this means that there will be obsolete classes/metaclasses hanging around until I send #removeAllObsoleteSubclasses ? Even moreâ¦the values in WeakKeyToCollectionDictionary (the class of the class var ObsoleteSubclasses in Behavior) are WeakArrayâ¦ so they shouldn't be bothering. Sometimes the test is yellowâ¦a wait a little bit and then if I run it is greed again. When it fails, it is always the same, metaclassesBeforeTest has 1 less inst than Metaclass instanceCount. Sometimes it is the other way around and it has 1 more instead of one less. Thanks a lot for any clueâ¦ testXXX "Tests materialization of a hierarchy of classes that are not defined in the image and classes that indeed are defined. In addition we test to correctly create the necessary amount of classes and metaclasses." | classes a b c d metaclassesBeforeTest classSubclassesBeforeTest | 3 timesRepeat: [Smalltalk garbageCollect]. metaclassesBeforeTest := Metaclass instanceCount. classSubclassesBeforeTest := Class allSubclasses size. a := Object subclass: #Xaaa instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: ''. b := a subclass: #Xbbb instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: ''. c := a subclass: #Xccc instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: ''. d := Date subclass: #Xddd instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: ''. classes := Array with: a with: b with: c with: d. classes do: [ :aClassOrTrait | aClassOrTrait removeFromSystem ]. classes := nil. a := b := c := d := nil. 6 timesRepeat: [Smalltalk garbageCollect].
