StartupLoader in Windows
by phil＠highoctane.be Feb. 28, 2014

Feb. 28, 2014

I was looking at the comment in StartupLoader which appears to be plain wrong. First, "to know the read values, check FileDirectory preferencesGeneralFolder" Mmmh, no FileDirectory class of course. So, implementors give the StartupLoader itself. Where: StartupLoader class >> preferencesGeneralFolder ^ FileLocator preferences asFileReference / 'pharo'. Argh, no .config as mentioned. This gives an issue with ZeroConf as ZeroConf creates a pharo-ui et pharo scripts, which then make it impossible to have a pharo folder there as well. Now, the FileLocator preferences gets into the PreferencesHandler and there is a buildActionList there. buildActionList "All found files will be executed." | directories | directories := OrderedCollection new. directories add: [ self lookInGeneralPreferencesFolder ]. directories add: [ self lookInPreferencesVersionFolder ]. directories add: [ self lookInImageFolder ]. ^ directories So: preferencesVersionFolder ^ self preferencesGeneralFolder asFileReference / SystemVersion current dottedMajorMinor and lookInImageFolder ^ self lookInFolder: FileSystem workingDirectory forFilesMatching: StartupLoader startupScriptName. startupScriptName ^ 'startup.st' startupPreferencesVersionFolderScriptName ^ 'startupPharo',SystemVersion current dottedMajorMinor,'.st' startupGeneralPreferencesFolderScriptName ^ 'startupPharo.st' Well... this is weird. What is the intention really? So, wouldn't we have another thing than 'pharo' in there ? Like pharo-prefs? What does work for you? ------ "StartupLoader searches for and executes .st files from certain locations. To find these it searches for a '.config' folder in the folder next up from where the image file sits. Then it looks in the next folder up again and so on until reaching the root folder. When a '.config' folder is found, StartupLoader looks within this for a 'pharo' folder. This contains the startup scripts common to all versions of Pharo, and also optionally a folder per Pharo version holding startup scripts suitable for that version only. So a typical directory layout might be... .../some/folders/pharo/Content/Resources/pharo.image. .../some/folders/pharo/Content/Resources/startup.st .../some/folders/.config/pharo/author.st .../some/folders/.config/pharo/useSharedCache.st .../some/folders/.config/pharo/1.4/mystartupFor14only.st .../some/folders/.config/pharo/2.0/mystartupFor20only.st (**Note however that '.config' is an invalid filename on Windows, so '..config' is used instead) IMPORTANT: StartupLoader will search for a folder '.config' starting from the image directory until the root of the filesystem. What happens if no folder is found? It creates '.config' in the image folder. However, it is recommended that you create the '.config' following the standard, that is, in the $HOME. To know the real values for you... Print the result of "FileDirectory preferencesGeneralFolder" which holds the startup scripts common to all versions of Pharo. Print the result of "FileDirectory preferencesVersionFolder" which holds the startup scripts specific to the version of the current image." ----------- Phil

Pharo-Business: a new mailing-list
by Pharo4Stef Feb. 28, 2014

Feb. 28, 2014

Dear Pharoers and Smalltalkers from all over the world We would really like to push business in our community and we believe that it is important to create a community around business questions. We created a new mailing-list http://lists.pharo.org/mailman/listinfo/pharo-business_lists.pharo.org The idea is to identify - potential market - missing technical solutions that we could build together - share technical assets from a business perspective (which frameworks for what). We hope that you will like the idea and that more business can emerge!

Could someone fwd this to the Seaside list (and possibly check my email) as it seems that my posts aren't getting through since a while. --- Like this: renderContentOn: html html anchor onClick: (((html jQuery: 'html head') find: 'title') text: 'NEW'); with: 'Update Title'.

Floats problem with SIXX between Pharo and GemStone
by Mariano Martinez Peck Feb. 27, 2014

Feb. 27, 2014

Hi guys, When I export SmallDoubles with SIXX in GemStone it generates something like this: <sixx.object sixx.id="15" sixx.name="close" sixx.type="SmallDouble" >1.0000000000000000E-02</sixx.object> This is because "0.01 asString" -> '1.0000000000000000E-02' Then I want to load this in Pharo. So first problem is that of course SmallDouble doesn't exist. So I did: aSixxShapeChangeStream shapeChangers at: #SmallDouble put: Float. But then, SIXX use Float >> readFrom: aStream "Answer a new Float as described on the stream, aStream." ^(super readFrom: aStream) asFloat So, of course " Float readFrom: '1.0000000000000000E-02' " -> 1.0 So my 0.01 in gemstone become 1.0 in Pharo.... Am I doing something wrong or this is expected? What is the best workaround? In GemStone I could print the SmallDouble in the XML with a method like Float >> xmlRepresentation ^ String streamContents: [:strm | self printOn: strm base: 10] Is this the correct approach? If true, I guess I should define: Float >> sixxContentOn: aStream indent: level context: dictionary aStream nextPutAll: self xmlRepresentation Thoughts? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

about dateAndTime and TimeStamp
by Pharo4Stef Feb. 27, 2014

Feb. 27, 2014

one of these days we will have to remove TimeStamp because it just adds noise to the system (in fact I would not have any problem to see DateAndTime renamed as timestamp - but having the two for nothing looks useless to me). Stef

Authorize upArrow in binary symbols
by Nicolas Cellier Feb. 27, 2014

Feb. 27, 2014

Though being reserved for return statements, the upArrow ^ could perfectly be accepted as a character composing a binary selector, like the verticalBar | already is. Indeed there is no ambiguity, since the return ^ is always prefixed, while a binary message never is... (well, except in the method source, but method source must begin with selector, it cannot begin with a return statement, so no ambinguity there neither...). I don't plan to use or add such selector in core Squeak/Pharo, but I think that it is important to allow a variety of selectors : it allows the most simple DSL : one using Smalltalk syntax (no need to define a new syntax, a new parser, etc...). If we did it for |, I don't see why we shouldn't for ^. Note that we recently also extended usage of - at any place in binary selectors (it was restricted to first position previously), though no core message is concerned so far. The main objection could be that a missing period before a return statement won't be reported, but interpreted as a message send... like in: x := a+b ^x But I don't think it's really a feature stopper. It's very easy to modify the old Compiler and shouldn't be that hard in Opal too. I'll try and push a prototype in Squeak inbox this evening. What do you think?

iPad version does not work ?
by jannik laval Feb. 27, 2014

Feb. 27, 2014

Hi list, Does anyone try to load Pharoon iPad ? In the past, the version 1.4 worked with XCode 4.4. I just tried to recompile it with the new XCode (5.0.2). The VM seems to work, but the pharo 1.4 image freezes. Any idea ? -- ~~Jannik Laval~~ Ãcole des Mines de Douai Enseignant-chercheur http://www.jannik-laval.eu http://car.mines-douai.fr/
