How to view hierarchy of multiple classes in a package?
by Tim Mackinnon July 8, 2017

July 8, 2017

Hi guys - I'm trying to get back into pharo, and check out the advances in v5. Anyway, if I look at a package in the system browser, it shows me classes in that package (i think my terminology is right here?). What confuses me, is his I can see the hire hybrid the classes in relation to each other? The hier button just shows the hierarchy of the selected class and not in relation to the others? I'm sure at some point pharo and squeak let you see the related hierarchies of all the classes in the package didn't it? This is really useful to help understand the relationship between classes and pure risky identify useful refactorings. I can't see how to do this in pharo anymore? Is this functionality that has been lost (which seems a shame)? Or am I missing another useful browsers? Tim Sent from my iPhone

Updating my remote pharo to latest codebase..
by sergio ruiz July 7, 2017

July 7, 2017

Hi, all.. I think have most everything figured out on running and managing my remote image. I have been running i headless and using PharmIDE.. but i canât figure out how to update a package to the latest version.. In my case, i have a few packages with source code, tests, etc. set up with a metacello configuration. Normally, I would just use Â VNC and monticello to update it while it was still running.. but VNC is causing me all sorts of issues, and i feel like thereâs a better way. since this is in alpha, i am keeping data in the image.. but once this is no longer an issue, i will just build a new new image every time with a script.. but for now, what is the best way to handle this? Thanks! ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Are we able to run pharo images in a read only environment?
by Tim Mackinnon July 6, 2017

July 6, 2017

Hi - I am trying to run a pharo image in lambda (as an experiment) - however I get an error from Pharo about not being able to write to the changes file? As I am just evaluating some code - Iâm not really coding, so donât need a changes file - is there a command line option to not require it? Also, am I running pharo the most efficient way - Iâm using eval on the command line and referencing a class with a class method - but is this the best way? Thanks, Tim "errorMessage": "Command failed: ./pharo Pharo.image eval \"Lambda processJSON: '{\"key3\":\"value3\",\"key2\":\"value2\",\"key1\":\"value1\"}'\"\n'Pharo cannot write to the changes file named /var/task/Pharo.changes.\n\nPlease check that you have write permission for this file.\n\nYou won''t be able to save this image correctly until you fix this.'\n\u001b[31mError: Can't find the requested origin\n\u001b[0mUnixResolver(PlatformResolver)>>cantFindOriginError\n[ self cantFindOriginError ] in UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed: in Block: [ self cantFindOriginError ]\nUnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:or:\nUnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:\nUnixResolver>>home\n[ self home / '.config' ] in UnixResolver>>preferences in Block: [ self home / '.config' ]\nUnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:or:\nUnixResolver>>preferences\nUnixResolver(FileSystemResolver)>>resolve:\nSystemResolver(FileSystemResolver)>>unknownOrigin:\nSystemResolver(FileSystemResolver)>>resolve:\nInteractiveResolver>>unknownOrigin:\n[ self unknownOrigin: origin ] in InteractiveResolver>>resolve: in Block: [ self unknownOrigin: origin ]\nIdentityDictionary(Dictionary)>>at:ifAbsent:\nInteractiveResolver>>resolve:\nFileLocator>>resolve\nFileLocator(AbstractFileReference)>>exists\nGlobalIdentifierStonPersistence(GlobalIdentifierPersistence)>>shouldCallPreviousPersistence\nGlobalIdentifierStonPersistence(GlobalIdentifierPersistence)>>ensure:\nGlobalIdentifier>>ensure\nGlobalIdentifier class>>initializeUniqueInstance\nGlobalIdentifier class>>uniqueInstance\nSystemSettingsPersistence class>>resumeSystemSettings\n[ :persistence | persistence resumeSystemSettings ] in PharoCommandLineHandler>>runPreferences in Block: [ :persistence | persistence resumeSystemSettings ...etc...\nBlockClosure>>cull:\nSystemDictionary(Dictionary)>>at:ifPresent:\nSmalltalkImage>>at:ifPresent:\nPharoCommandLineHandler>>runPreferences\nPharoCommandLineHandler>>activate\nPharoCommandLineHandler class(CommandLineHandler class)>>activateWith:\n\u001b[0m", "errorType": "Error", "stackTrace": [ "'Pharo cannot write to the changes file named /var/task/Pharo.changes.", "", "Please check that you have write permission for this file.", "", "You won''t be able to save this image correctly until you fix this.'", "\u001b[31mError: Can't find the requested origin", "\u001b[0mUnixResolver(PlatformResolver)>>cantFindOriginError", "[ self cantFindOriginError ] in UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed: in Block: [ self cantFindOriginError ]", "UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:or:", "UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:", "UnixResolver>>home", "[ self home / '.config' ] in UnixResolver>>preferences in Block: [ self home / '.config' ]", "UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:or:", "UnixResolver>>preferences", "UnixResolver(FileSystemResolver)>>resolve:", "SystemResolver(FileSystemResolver)>>unknownOrigin:", "SystemResolver(FileSystemResolver)>>resolve:", "InteractiveResolver>>unknownOrigin:", "[ self unknownOrigin: origin ] in InteractiveResolver>>resolve: in Block: [ self unknownOrigin: origin ]", "IdentityDictionary(Dictionary)>>at:ifAbsent:", "InteractiveResolver>>resolve:", "FileLocator>>resolve", "FileLocator(AbstractFileReference)>>exists", "GlobalIdentifierStonPersistence(GlobalIdentifierPersistence)>>shouldCallPreviousPersistence", "GlobalIdentifierStonPersistence(GlobalIdentifierPersistence)>>ensure:", "GlobalIdentifier>>ensure", "GlobalIdentifier class>>initializeUniqueInstance", "GlobalIdentifier class>>uniqueInstance", "SystemSettingsPersistence class>>resumeSystemSettings", "[ :persistence | persistence resumeSystemSettings ] in PharoCommandLineHandler>>runPreferences in Block: [ :persistence | persistence resumeSystemSettings ...etc...", "BlockClosure>>cull:", "SystemDictionary(Dictionary)>>at:ifPresent:", "SmalltalkImage>>at:ifPresent:", "PharoCommandLineHandler>>runPreferences", "PharoCommandLineHandler>>activate", "PharoCommandLineHandler class(CommandLineHandler class)>>activateWith:", "\u001b[0m", "ChildProcess.exithandler (child_process.js:204:12)", "emitTwo (events.js:106:13)", "ChildProcess.emit (events.js:191:7)", "maybeClose (internal/child_process.js:886:16)", "Process.ChildProcess._handle.onexit (internal/child_process.js:226:5)" ] }

The PharoV60.sources file is not located in the same directory as the VM binary.

Where did the XMLDOMParse go?
by Twan van der Schoot July 6, 2017

July 6, 2017

Hi All, Question: Is there any Pharo "endorsed" XML support for Pharo v6.0 and if so, where can I find it? I'm new to Pharo and I'm currently cutting my teeth into v6.0 attempting to program the XML-Browser example on Pharocasts. I fully realise that that example is based on v1.4 of Pharo. However is struck me as strange that any support for XML lacks from v6.0 and even the (default) Monticello packages repo. Can some one provide me with some hints, Thanks for reading. Best regards, Twan van der Schoot
