Got a look inside the UIDevice.h and there is typedef NS_ENUM(NSInteger, UIUserInterfaceIdiom) { #if __IPHONE_3_2 <= __IPHONE_OS_VERSION_MAX_ALLOWED UIUserInterfaceIdiomPhone, // iPhone and iPod touch style UI UIUserInterfaceIdiomPad, // iPad style UI #endif } Do we have any special defined thing related to that?

[Pharo-project] iOS VM build... oops, not working
by phil＠highoctane.be Feb. 27, 2013

Feb. 27, 2013

Hello, Looks like there is no Xcode project anymore in the last version of the build. Right, it looks like the same as the OSX one. First, I had to remove the FT2Plugin since it failed badly. Also there is no support for the PharoVMBuilder in there. And no iPhone.image anymore. Which has been renamed iOS.image and required fetching from the CI. (Also, having the bad URL since the move). Anyway, got that done. Now, I am facing this (and I removed all of Xcode 4.2, cleaned the box, reinstalled Xcode 4.3 And also set SDK to the right one and the platform to armv7 before generating the sources. Now, I get: Scanning dependencies of target IOSPlugin [ 0%] Building C object IOSPlugin/CMakeFiles/IOSPlugin.dir/Users/philippeback/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/src/plugins/IOSPlugin/IOSPlugin.c.o In file included from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIApplication.h:13, from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIViewController.h:10, from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIActivityViewController.h:9, from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIKit.h:14, from /Users/philippeback/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/build/iStackVM_Prefix.pch:7, from <command-line>:0: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIDevice.h:33: error: expected identifier before â}â token /Users/philippeback/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/src/plugins/IOSPlugin/IOSPlugin.c: In function âprimitiveShowKeyboardâ: /Users/philippeback/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/src/plugins/IOSPlugin/IOSPlugin.c:124: warning: implicit declaration of function âsqShowKeyboardâ make[2]: *** [IOSPlugin/CMakeFiles/IOSPlugin.dir/Users/philippeback/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/src/plugins/IOSPlugin/IOSPlugin.c.o] Error 1 make[1]: *** [IOSPlugin/CMakeFiles/IOSPlugin.dir/all] Error 2 make: *** [all] Error 2 [PhilMac:~/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/build philippeback$] gvim /Users/philippeback/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/build/iStackVM_Prefix.pch [PhilMac:~/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/build philippeback$] sudo make [ 0%] Building C object IOSPlugin/CMakeFiles/IOSPlugin.dir/Users/philippeback/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/src/plugins/IOSPlugin/IOSPlugin.c.o In file included from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIApplication.h:13, from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIViewController.h:10, from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIActivityViewController.h:9, from /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIKit.h:14, from /Users/philippeback/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/build/iStackVM_Prefix.pch:3, from <command-line>:0: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIDevice.h:33: error: expected identifier before â}â token /Users/philippeback/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/src/plugins/IOSPlugin/IOSPlugin.c: In function âprimitiveShowKeyboardâ: /Users/philippeback/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/src/plugins/IOSPlugin/IOSPlugin.c:124: warning: implicit declaration of function âsqShowKeyboardâ make[2]: *** [IOSPlugin/CMakeFiles/IOSPlugin.dir/Users/philippeback/Documents/Smalltalk/2-MyWorkspaces/workspaceVMiOSFromBook/blessed/src/plugins/IOSPlugin/IOSPlugin.c.o] Error 1 make[1]: *** [IOSPlugin/CMakeFiles/IOSPlugin.dir/all] Error 2 make: *** [all] Error 2 For some reason the pch contains ^M characters all over.

[Pharo-project] Progress Indication seems way off
by Sven Van Caekenberghe Feb. 27, 2013

Feb. 27, 2013

Did anybody else notice this ? For me, in #20572, progress indication seems to be off, like when I run unit tests, there is simply no progress bar, it jumps from 0 to 369 just like that. I am also missing some but not all progress bars while doing a system update. Sven

[Pharo-project] [ANN] ZTimestamp[Precise]SNTPClient
by Sven Van Caekenberghe Feb. 27, 2013

Feb. 27, 2013

Hi, It is often important, especially for server applications, to know if the current local clock is still OK. The standard way for doing that is part of NTP (http://en.wikipedia.org/wiki/Network_Time_Protocol) I implemented two SNTP clients (one with ZTimestamp's second precision and another one using DateAndTime's nanosecond precision) that can be used to check the difference between the local clock and the clock of any NTP server. ZTimestampPreciseSNTPClient new clockDifference. -0:00:00:00.005786228 This reports that the difference between the local and remote clocks is in the order of 5ms, as computed in one specific way. Other queries are related to the Clock synchronisation algorithm. ZTimestampPreciseSNTPClient new localClockOffset. 0:00:00:00.065466869 ZTimestampPreciseSNTPClient new roundtripDelay. 0:00:00:00.037001908 In practice the following would be a useful practical check. ZTimestampPreciseSNTPClient new enforceClockDifference: 2 seconds ifFail: [ :delta | self warn: ('Clock difference {1} > 2s' format: { delta }) ]; close. As NTP uses UDP datagrams, this is a nice example for that as well. The code can be found in the following repository: http://mc.stfx.eu/Neo It is probably easiest to load the ZTimestamp configuration using the Configuration Browser and then load the bleeding edge version (it is not in de released version). The code is self-contained and loads cleanly. ConfigurationOfZTimestamp project bleedingEdge load. The client contacts a server from pool.ntp.org. The code does only deal with a limited aspect of NTP, which is rather complex and wonderful subject matter (http://tools.ietf.org/html/rfc2030) My goal was to get a dependable result, not be be super accurate. Enjoy. Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

[Pharo-project] pharo-contribution triggering for new Pharo versions
by Pavel Krivanek Feb. 27, 2013

Feb. 27, 2013

Hi, how to setup the jobs on pharo-contribution to be executed with every new Pharo version? I tried simply to setup URL trigger on http://pharo.gforge.inria.fr/ci/image/20/ but it was not started for new versions. BTW, the job PharoKernel2.0-ReloadByMonticello that loads everyting back to shrinked kernel is green again. -- Pavel

[Pharo-project] [Horrible Error]: Class creation not logged in changes

Issue 7609: [Horrible Error]: Class creation not logged in changes https://code.google.com/p/pharo/issues/detail?id=7609 #20567 1. Create a class in Nautilus pane 2. Recover lost changes Class creation will not be there. This is TERRIBLE! I was relying on change recovery when my image crashed and I found out that I had to manually recreate all the classes w. hierarchy before I could file-in my methods. Ugh :/ Of course I will be fine ;) but we can not expose new users to this... -- View this message in context: http://forum.world.st/Horrible-Error-Class-creation-not-logged-in-changes-t… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] iOS VM and external bluetooth keyboard
by phil＠highoctane.be Feb. 27, 2013

Feb. 27, 2013

After a long hiatus, I've been back at hacking the iOS VM for supporting proper keystrokes from an external bluetooth keyboard. I guess I've nailed it down technically speaking (and learned a serious bunch about how the iOS VM is connecting Pharo with the world. Now, I have to get this right in the image. This will allow to have the full support for bindings on the iPad (which is what I am interested in). I would just love being able to program on the iPad like on a Dynabook! Stay tuned. Phil
