[Pharo-project] Error when trying to create a package
by Jim Menard May 21, 2009

May 21, 2009

When every I try to create a package in the browser, I see an error. Inside OBPackageOrClassNode>>shouldRefresh: the value of "ann event" is nil, so the call to itemKind blows up. I believe I have the latest version of Pharo, with all updates as of a day or two ago. This has been happening for a long time, though. Am I doing something wrong, or is this a bug?

[Pharo-project] Win32Setup - custom VM and app tutorial
by Torsten Bergmann May 21, 2009

May 21, 2009

Hi, there is now a ready made setup for installing pharo on windows. http://gforge.inria.fr/frs/download.php/22307/setup_pharo_0.0.0.1.exe It is available in the Win32 Setup section on http://gforge.inria.fr/frs/?group_id=1299 Far from perfect, but working. Use at your own risk! Additionally you will find a short tutorial below on how to build a custom Pharo VM and distribution for Win32 Systems. It can also help if you want to create a (commercial) application based on pharo. Have fun Torsten ----------------------------------------------------------------------------------------------- SECTION A - Building a Pharo windows VM ======================================= Since Pharo has its roots in Squeak Smalltalk the Squeak virtual machine is used. These steps allow you build a more "pharoized" virtual machine: - setup the tools environment for compiling the VM as described on [1] - grab the lates Squeak VM sources from [2], here we use the squeak 3.11.2 VM so we download "SqueakVM-Win32-3.11.2-src.zip" - extract it into a directory of your choice - make a parallel copy of directory winbuild and name it "pharobuild" - in the "pharobuild" directory -- delete the three *.ico files from squeak (squeak.ico, squeak2.ico and squeak3.ico) -- copy the pharo.ico file from [3] into the directory -- copy the splash.bmp file from [4] into the directory -- edit "Makefile" with a text editor and set the name of the new VM to "Pharo" in line 12 ("VM = Pharo"), note the uppercase -- rename the file "Squeak.def.in" into "Pharo.def.in" (note the uppercase) -- rename the file "Squeak.rc" into "Pharo.rc" (note the uppercase) -- edit "Pharo.rc" with a text editor and modify all 3 icon definitions to use "pharo.ico" now -- run "make" to build the VM -- you will now find a "Pharo.exe" (with the custom icon) and two external plugins ("FT2Plugin.dll" and "SqueakFFIPrims.dll") in the pharobuild\obj\vm directory SECTION B - Building a pharo distribution ========================================= - create a new directory "pharodist" - copy the "Pharo.exe", "FT2Plugin.dll" and "SqueakFFIPrims.dll" built in section A into this directory - also copy splash.bmp into this directory - download SqueakV39.sources.zip from [5] - extract the file "SqueakV39.sources" from this ZIP right into your "pharodist" directory (make sure you extract it exactly into this folder so you have a "pharodist/SqueakV39.sources" file - Download the latest pharo dev image (here we use pharo0.1-10309dev09.05.3.zip from [6]) and extract it into your "pharodist" directory - from this ZIP you should now extract the *.image file and the *.changes file into your "pharodist" directory (you should now have a "pharodist/pharo0.1-10309dev09.05.3.changes" and "pharodist/pharo0.1-10309dev09.05.3.image") - you can start pharo by dragging the "pharo0.1-10309dev09.05.3.image" onto the "Pharo.exe" file - note that automatically a new file "Pharo.ini" is created in your "pharodist" directory - save the image as "pharo.image" (you should now have a pharo.image and pharo.changes file - delete the old "pharo0.1-10309dev09.05.3.changes" and "pharo0.1-10309dev09.05.3.image" file - if you wish to further customize the application you can set some parameters in the Pharo.ini file (a list of all available parameters can be found at [7]) SECTION C - Building a setup ============================ - copy "Pharo.ico" into the "pharodist" directory - create a file "license.rtf" in the "pharodist" directory and clip the license from pharo-project.org into this file - download and install the free NSIS installer package, here we use version 2.42 from [8] - also download the file "ZIPDLL.zip" plugin from [9] - Extract ZipDLL.dll to directory "Plugins" in your NSIS installation - Extract ZipDLL.nsh to directory "Include" in your NSIS installation - copy the file "setup.nsi" file (attached to this mail) to your "pharodist" directory and compile it using NSIS (right click on the file and select "Compile NSIS script" from the context menu - you should now have a "setup_pharo_0.0.0.1.exe" ready for distribution - easy, istnt it? Things to improve: ================== - better looking icons for pharo exe (with transparency) - setup script with custom header on the installer wizard (MUI_HEADERIMAGE_BITMAP, etc) - setup script with installer and uninstaller icons (MUI_ICON, MUI_UNICON) - better version schema - automated build on a build machine (if someone has a windows box accessible from the web tell us) - ...

[Pharo-project] preferences clean-up
by Alain Plantec May 20, 2009

May 20, 2009

Hi all, I think we can remove following preferences: decorateBrowserButtons, menuButtonInToolPane, optionalButtons and smartUpdating. decorateBrowserButtons : always true menuButtonInToolPane : always false optionalButtons : always true smartUpdating: always true what do you think ? Cheers Alain decorateBrowserButtons "Governs whether certain buttons, such as the Inheritance button, should bear colors that provide user feedback on their applicability" menuButtonInToolPane "when true, button panes in the various tools will sport a button which brings up the message-list menu" optionalButtons "If true, then optional buttons will be used in certain standard tools, including browsers, message lists, fileLists, changeLists, and debuggers" smartUpdating "If true, then morphic tools such as browsers and inspectors will keep their contents up to date automatically, so that if something changes anywhere, the change will be reflected everywhere."

[Pharo-project] Smalltalk idiom
by Ramiro Diaz Trepat May 20, 2009

May 20, 2009

I have a simple question regarding the use of a proper idiom.I had to create a matrix (n X m) of random values and I used a line similar to this one: NMatrix withRows: ((1 to: n) collect: [ :i | random next: m ]). Since Smalltalk is so neat for its collection handling, I obviously did not like to write that line. I thought that I did not want to explicitly create the interval, nor use a block that requires an argument that I also don't use. The question, finally, is if there an elegant way of replicating the behaviour of #collect: but without the argument? In my case, I thought it would be great for Integer to have something like #timesCollect: that would allow me to rewrite the line above as: NMatrix withRows: (n timesCollect: [ random next: m ]) Does anyone else think that this would be an useful method to have? Cheers r.

[Pharo-project] question about OCompletion
by Gabriel Brunstein May 19, 2009

May 19, 2009

How can I change the packages that I am working on with OCompletion? I think it is included in the last version of pharo so I could't specify it during the installation.

[Pharo-project] Understanding of new Eliot Closures
by Mariano Martinez Peck May 19, 2009

May 19, 2009

Hi! I am trying to make Glorp work on Pharo, and I having some problems. In squeak I inspect [] and I see I have a BlockContext object. In latest Pharo, I get a BlockClosure. I guess this is about Eliot changes ? Now, Glorp has 5 methods extension in BlockContext. I saw BlockContext and BlockClosure and they have no hierarchy in common. So, if I want Glorp to work in squeak and pharo I must copy all that 5 methods from BlockContext to BlockClosure? is there a better solution ? I tried the first one and seems to work ok but I don't know if it is correct. Thanks in advance, Mariano
