Pharo By Example - VM issues
by Johan Fabry Nov. 28, 2011

Nov. 28, 2011

Hi all, I'm evaluating PBE (1.0) because my nephew is starting to get interested in programming :-) There is a VM issue though: the PBE website refers the pharo website to download the VM, and the only VM I can find is in the 1.3 download page. This VM however crashes with the PBE image (MacOS). It works with the latest squeakvm (non-cog) though. I think, as a minimal-effort patch, it would be good to have the PBE website refer to squeakvm.org and clearly indicate that to run the PBE image a non-cog VM should be used. Idem on the pharoproject website.

Creating a FSReference
by Sean P. DeNigris Nov. 26, 2011

Nov. 26, 2011

What's the easiest way to create a reference to, say, /dev from a string? I came up with "FSFilesystem disk root resolveString: '/dev'." Anything better? Also, what's the difference between FSReference>> resolve: resolveString: ? They both seem to do the same thing in this case. Thanks.

Restoring a Morph's Default Mouse Handling
by Sean P. DeNigris Nov. 25, 2011

Nov. 25, 2011

I always forget how to do this, so I added a chapter to the online book: As soon as you define #handlesMouseDown: in your Morph subclass, you lose the default behavior where a morph is picked up when clicked on. To restore this behavior, compile the following two methods in your morph class: mouseDown: anEvent anEvent hand waitForClicksOrDrag: self event: anEvent. startDrag: anEvent anEvent hand grabMorph: self. http://book.pharo-project.org/book/LanguageAndLibraries/GUI/restoringdefaul… -- View this message in context: http://forum.world.st/Restoring-a-Morph-s-Default-Mouse-Handling-tp4097353p… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

scripting pharo
by t olschewski Nov. 25, 2011

Nov. 25, 2011

is there a standard way of using pharo 1.3 OneClick (or squeak 4.2 All-in-One) for scripting tasks ? With python, I simply: * write a script foo.py * use extra classes by writing "import xyz" * run "python foo.py" or even simpler: * #!/usr/bin/python -- View this message in context: http://forum.world.st/scripting-pharo-tp4089006p4089006.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I want a Window that shrinks to fit its contents, like a PluggableDialogWindow, but that has a title bar and buttons, like a Standard Window. Any ideas? Thanks.

pharo wrapper script suggestion and a question
by t olschewski Nov. 24, 2011

Nov. 24, 2011

what do you think about modifiying the wrapper script pharo.sh (OneClick edition) slightly in order to alleviate scripting: a) pharo.sh: passing "$@" over to pharo: ... exec "$BASE/pharo" \ ... ... "$ROOT/Contents/Resources/pharo.image" \ "$@" b) making a second script, pharo-headless.sh: ... exec "$BASE/pharo" \ -headless \ ... ... "$ROOT/Contents/Resources/pharo.image" \ "$@" Test: pharo-headless anyScript.st And another Question: is there a better way of forcing "pharo -headless" to quit, better than writing "WorldState quitSession." in every script ? -- View this message in context: http://forum.world.st/pharo-wrapper-script-suggestion-and-a-question-tp4099… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Moving package extension methods into new package
by Sean P. DeNigris Nov. 23, 2011

Nov. 23, 2011

I wanted to move all the extension methods from a package into another package. I came up with the following. Is there a better way? oldPackageName := 'LivingCode-bdd extensions'. newPackageName := 'BDDExtensions'. package := PackageInfo named: oldPackageName. extendedClasses := package extensionMethods collect: [ :e | e methodClass ] as: Set. extendedClasses do: [ :c | c organization renameCategory: '*', oldPackageName toBe: '*', newPackageName ]. -- View this message in context: http://forum.world.st/Moving-package-extension-methods-into-new-package-tp4… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
