[Pharo-project] Suggestion: rename some methods for consistency
by DougEdmunds April 25, 2011

April 25, 2011

The vast majority of example methods follow a consistent naming pattern where the word 'example' starts the method name. There's a handful that don't. The advantage of this approach is that all the examples appear together in the browser list of methods. I suggest that these methods be renamed: BorderedMorph class >> gradientExample --> exampleGradient SimpleHierarchicalListMorph class >> submorphsExample --> exampleSubmorphs PluggableMenuSpec class >> withOneSingleItemExample --> exampleWithOneSingleItem PluggableMenuSpec class >> withSubMenuExample --> exampleWithSubMenu PluggableMenuSpec class >> withTwoSimpleItemsExample --> exampleWithTwoSimpleItems DigitalSignatureAlgorith >> writeExamplesToDisk --> exampleWriteToDisk UITheme class >> textEntryWithCompletionDialog --> exampletextEntryWithCompletionDialog UITheme class >> closeExampleDialogs --> exampleCloseDialogs (I've excluded test and testcase examples from this list). -- View this message in context: http://forum.world.st/Suggestion-rename-some-methods-for-consistency-tp3473… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

I called these 'leds' unit-test icons because thats what they are (in my mind and I guess also for a lot of other people). So using them for anything else is not a good idea at all.

[Pharo-project] Which packages should we include of metacello for Pharo 1.3?
by Mariano Martinez Peck April 25, 2011

April 25, 2011

Hi Dale and the rest. In Pharo 1.2 we used to include these packages/groups from Metacello: #('Metacello-Core' 'Tutorial' 'UI' 'Metacello-ProfStef' 'Metacello-Help'); and #('Tests') Is this still valid? because I decided them a couple of months ago...so maybe they are not valid anymore. For example, do we want the MetacelloBrowser or things like that ? and the MetacelloToolbox ? Thanks -- Mariano http://marianopeck.wordpress.com

Hi alain. If I do cmd + f and I type something in the input, the only way to get the cursor in the result is by clickling in the "search" button. I would expected to be able to hit enter in addition. What do you think? Thanks -- Mariano http://marianopeck.wordpress.com

[Pharo-project] Reproducible Cog crash but no info to get an idea...
by Mariano Martinez Peck April 25, 2011

April 25, 2011

Hi. We are having a crash in Fuel, which doesn't crash with the standard VM. To reproduce, take a Pharo 1.2 image and load the attached mcz. You will see that method: #materializeKeysAndValuesTo:with:size: has a "self halt" inside. If you ran the test FLCreateClassSerializationTest >> testCreateWithMethod it will crash. If you remove the "self halt" from #materializeKeysAndValuesTo:with:size: it works... I debuged it with GDB and I don't know why, I can ONLY see the last two instrunctions, which is a longAt: -8 I attach screenshot. A bt or a call printAllStacks() doesn't show me anything. If I run from a console, the only thing I get is a: Segmentation fault Smalltalk stack dump: Bus error I have no idea what can be happening. Thanks for any clue... -- Mariano http://marianopeck.wordpress.com

Re: [Pharo-project] [Vm-dev] Debugging Cog crash
by Schwab,Wilhelm K April 24, 2011

Eliot, I modified the one-click's shell script as shown below and ran it from a terminal. It still says only "Segmentation fault." I could be doing this incorrectly or maybe not looking in the correct place for the output??? My first attempt was to add -sendTrace=9 (note case), and it complained, which is vastly better than ignoring my mistake; it also suggests that I got -sendtrace=9 correct, or it would presumably complain again. Did I botch it, or is it really quitting before it reaches Smalltalk code? If you suspect the latter, is there something else we can do to prove it, and/or what's next? I am not opposed to building from source. I avoided it for a while because I was afraid that I would "hack" the vm again and not really fix my FFI oddities. I am close to having the latter sorted, and can probably now trust myself with vm source :) Bill #!/bin/sh # path ROOT=`dirname $0` LINUX="$ROOT/Contents/Linux" RESOURCES="$ROOT/Contents/Resources" # icon gvfs-set-attribute \ "$0" \ "metadata::custom-icon" \ "file://$RESOURCES/Squeak.png" \ 2> /dev/null # execute exec "$LINUX/squeakvm" \ -sendtrace=9 \ -plugins "$LINUX" \ -encoding latin1 \ -vm-display-X11 \ "$RESOURCES/Pharo.image"
