Re: [Pharo-project] How to encrypt a password?
by Paul DeBruicker Nov. 22, 2013

Nov. 22, 2013

Hi Mariano, I've made a FFI library on Squeaksource that works on Linux. http://www.squeaksource.com/Cryptography/PasswordHashingFFI-PaulDeBruicker.… You need to install the 32 bit versions of libcrypt and libxcrypt if you're using a 64 bit linux os. Using crypt can hash passwords using MD5, DES, SHA256, SHA512. Using libxcrypt can hash passwords using bcrypt. If its for a new installation use bcrypt or SHA512 to hash the passwords. bcrypt is better because its slower, and allegedly future proof. to get a hashed password use BCryptLinuxFFI bcrypt:'mypassword' to check it against a stored hash use: BCryptLinuxFFI check:'mypassword' against: storedHash

[Pharo-project] TextAttribute, TextAction and TextDoIt or TextURL: not working
by phil＠highoctane.be Nov. 6, 2013

Nov. 6, 2013

I've been investigating with text. I found things that do work like: ((Text withAll: 'foo') , (Text string: '*' attribute: (TextAnchor new anchoredMorph: EllipseMorph new)) , (Text withAll: 'bar')) asMorph openInWorld. ((Text withAll: 'foo') , (Text string: '*' attribute: (TextAnchor new anchoredMorph: ThemeIcons confirmIcon)) , (Text withAll: 'bar')) asMorph openInWorld. But doing: ((Text withAll: 'foo') , (Text string: 'some link' attribute: (TextURL new url:'http://philippeback.eu')) , (Text withAll: 'bar')) asMorph openInWorld. gives me a nice purple 'some link' bit but clicking on it fails with MessageNotUnderstood: TextURL>>actOnClick:for:in:editor: Damn! Ideas on how to tackle this? TIA Philippe Back

[Pharo-project] Render images - Porting from Cincom VW to Pharo
by Emilia Oct. 15, 2013

Oct. 15, 2013

Hello! I'm porting code from Cincom Smalltalk to Pharo. It's a web application so I've got several WAComponent instances and one component which inherits from WAFileLibrary that renders images. In the original code ( the one that runned in VW) i had the following instance method in the component that inherits from WAFileLibrary: logoJpg ^ByteArray asPackagedString: '?=#?8@@PR$YIQ @A@ D@X@A @@C?8P))QW!)Y @@RT$*@@ @@@@G@AHA@0@......etc etc' But now when i run it in Pharo the debbugger doesn't recognize #asPackagedString: message. Does anyone know which method should I use in order to render that image? Thanks in advance! Mercy beaucoup! Emilia

[Pharo-project] Issue 3015: When a test is restarted in the debugger, #tearDown and #setUp and not send
by Hernan Wilkinson Aug. 28, 2013

Aug. 28, 2013

Hi, I added a new issue (that I think it could be see as an improvement, not an issue) that is related to debugging a test case written with SUnit. The problem is that when you restart a test in the debugger (either by pressing the restart button or compiling the method again) the changes made by the test to the objects initialized in the #setUp are not rollbacked. This change sends the messages #tearDown and #setUp to the test when restarting it, therefore letting the test in the same state as when it was run in the first place. I uploaded the solution to this issue (or improvement) to pharo inbox under SLICE-Issue-3015-RestartingATestFromTheDebuggerSendsTearDownAndSetUp-HernanWilkinson.2 I hope you like it!

[Pharo-project] Your earlier problems accessing Monticello
by Sven Van Caekenberghe April 23, 2013

April 23, 2013

Hi Guido, Some time ago you were unable to access Monticello from inside your particular network situation. http://forum.world.st/Unable-to-use-Monticello-in-last-images-from-Jenkins-… We just were able to solve a similar case. http://forum.world.st/Problem-downloading-packages-with-Monticello-from-Sma… Would it be possible to verify, first that your old problem still exists, and then try again with the following patch. SocketStream>>next: count "Read count elements and return them in a collection. If the receiver is #atEnd before count elements were read, return a smaller collection." ^ self nextInto: (self streamBuffer: count) That would be most helpful. Thx, Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

[Pharo-project] Spec DropLists
by Sean P. DeNigris April 16, 2013

April 16, 2013

Issue 6551: [ENH Spec]: Spec-ify DropListModel http://code.google.com/p/pharo/issues/detail?id=6551 Currently: self instantiateModels: #(dropList #DropListModel). item1 := DropListItem named: 'Red morph' do: self redMorphBlock. item2 := DropListItem named: 'Blue morph' do: self blueMorphBlock. item3 := DropListItem named: 'Green morph' do: self greenMorphBlock. dropList items: {item1. item2. item3}. I'd prefer if DropLists were uniform with the rest of Spec, namely: I'd have my domain class MyColor>>description ^ nameOfColor dropList items: {myRedColor. myBlueColor. myGreenColor}; displayBlock: [ :e | e description, ' morph' ]; whenSelectionChanged: [ :e | self showMorphFor: e ]. I'd prefer not to even know that DropListItem exists, and have the model take care of it for me. Something like: DropListModel>>items: aList "Populate the drop list with a list of objects" | items | items := aList collect: [ :e | DropListItem named: e printString do: [ ] ]. listHolder contents: items. Incidentally, #whenSelectionChanged: exists for DropListModels, but is broken. When an item is chosen from the drop list, the announcement received by this block has both new and old contents set to nil: Issue 6550: [BUG Spec]: DropListModel>>whenSelectionChanged: http://code.google.com/p/pharo/issues/detail?id=6550 Cheers, Sean -- View this message in context: http://forum.world.st/Spec-DropLists-tp4643694.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] [ANN] Fuel Release Version 1.9
by Martin Dias April 8, 2013

April 8, 2013

Hi all, We are happy to announce Fuel 1.9. Fuel is an open-source general-purpose object serialization framework developed in Pharo. You can find more information on our website [1]. The default set of packages of this version already comes in Pharo 2.0, so you it's not necessary to install it there. However, Fuel also works out-of-the-box in Pharo from 1.1 up to 2.0, as well as in Squeak 4.1 up to 4.4. You can see our documentation [2] for complete installation and use guides. Changes: - (feature) DoIt and not-installed CompiledMethods are fully serialized by default. - (fix) Date & DateAndTime (thanks Cami and Marcus) (already included in Fuel 1.8.1 and 1.8.2). - (feature) New hooks methods #fuelNew and #fuelNew: for custom instantiation (see "Hooking instance creation" in Customizing the Graph). - Globals: - Added #globalEnvironment: to specify where the globals are looked-up. (see "Changing the environment" in Managing Globals). - Explicit references to "Smalltalk globals" changed to "self class environment". - A SystemDictionary instance is not treated as global when it is not "Smalltalk globals". - Documentation: - General update - New Format Migration section. - New Built-in Header Support section. - (feature) Put back FLSerializer>>on:. - (optimization) New clusters for SmallInteger. - (optimization) New clusters for most common collections. - (feature) Built-in support for header (See Built-in Header Support): - pre and post materialization actions (clean closures). - attach additional objects. - materialize only the header. - (fix) Safer substitutions (see FLPluggableSubstitutionTest>>testPrivateExcluded). - (feature) Materialize .fuel files when drag&dropped in the image. - (cleanup) Removed unneeded cluster: FLWellKnownObjectsCluster. [1]: http://rmod.lille.inria.fr/web/pier/software/Fuel [2]: http://rmod.lille.inria.fr/web/pier/software/Fuel/Version1.9/Documentation<http://rmod.lille.inria.fr/web/pier/software/Fuel/Version1.8/Documentation> We want to thank developers of the community that enrich the project with code, issue reports and ideas. Have fun! Martin (on behalf of Mariano and Max, who worked a lot on this version)
