Read the book "Smalltalk-80, the language and its implementation" (the blue book), you will see how you can create new class/add new selector to it/and how to compile methods.

Programmatically generating classes and methods

by Sven Van Caekenberghe

Hi, Can someone point me to the right/official way to programmatically add classes and methods in Pharo 2.0 ? I can find some methods on Class and I guess the Compiler can be used as well, but it is all pretty confusing. I want the proper notifications and other mechanisms to be triggered. Thx, Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

(was thinking me as well, when tried to demonstrate the use of this function couple months ago :) there is very complicated machinery behind this function (most in C).. i have not much clues what happens, but i can imagine that it does something which interrupts/blocks VM thread (add there signals and stuff) until command finishes.. which VM can't handle.. i remember i did or checked something to make system() call working.. but i can't remember what exactly.

NB crash boom

by DeNigris Sean

Why is this simple experiment crashing the vm? It seemed like such a small change from the getenv example that I was sure it would succeed. Mac 10.8.2 with lastest nbcog vm... run: str "self run: 'open http://www.google.com'." <primitive: #primitiveNativeCall module: #NativeBoostPlugin error: errorCode > ^ self nbCall: #( int system (String str) ) module: NativeBoost CLibrary Thanks, Sean

Re: [Pharo-users] Ubuntu Phone

by S Krish

"Ubuntu Phone is based on the desktop version of Ubuntu<http://en.wikipedia.org/wiki/Ubuntu_(operating_system)> replacing standard graphical environment with mobile version of Unity<http://en.wikipedia.org/wiki/Unity_(user_interface)>. Its interface is based on Qt <http://en.wikipedia.org/wiki/Qt_(framework)> and QML <http://en.wikipedia.org/wiki/QML>.[5]<http://en.wikipedia.org/wiki/Ubuntu_Phone#cite_note-ecosys-5> ." Need to dig into my experiments with tiny core linux... where I could easily run Pharo UI. May require a bit of work to get the UI up and running.. very doable. Not sure of the market though with this being yet another mobile OS, given the muscle of Android, win 8, apple iOS, will it survive, unless Samsung adopts it.. or anyone like them.

As long as you can provide/compile the appropriate VM and accomodate the UI to be non native, it is doeable. Hilaire Le 14/02/2013 06:19, Paul Davidowitz a Ã©crit : > Can Pharo be used to develop apps for the new Ubuntu phone? > > > >

Can Pharo be used to develop apps for the new Ubuntu phone?

application specific settings browser - praise and a question

by MartinW

I managed very quickly to make an application specific settings browser using the Pharo Settings Framework (PharoBoids is more fun now: http://smalltalkhub.com/#!/~MartinWalk/Boids) The PBE2 chapter and the in-image-help are very good :) I just came across one problem (and found the solution on the mailinglist): ---------- If you want a package specific keyword, then your package must add a sepecific method to SettingTreeBuilder. for drgeosettings if should be: SettingTreeBuilder>> drgeosettings <settingPragmaProcessor> "Process a<drgeosettings> pragma" currentPragma methodClass theNonMetaClass perform: currentPragma selector with: self. ---------- and the short solution: ---------- SettingTreeBuilder>>drgeosettings ^ self systemsettings ---------- What is the reason for this need to define a specific method? Would it be possible to have one method for all the different pragmas? Is there some useful customisation that can be done in this specific method? -- View this message in context: http://forum.world.st/application-specific-settings-browser-praise-and-a-qu… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
