Hi, Thanks for the detail feedback. I provided some inlined answers and took the liberty of changing the thread subject.

What about a pragma? Or a package? Or a previous script that you used in the Playground? Or global variables? Or a method inside a class?

It is meant to provide a uniform interface to search all sorts of objects that you see interesting, and it even offers a cheap way to tweak its behavior to your needs. Here is a post that describes it in more details: http://www.humane-assessment.com/blog/introducing-gtspotter/ But, you raise an interesting debate on the difference between selectors and implementations. One problem with the MessageBrowser is that it does not allow me to search through the results. In Spotter, you type "do:" and then with Cmd+Shift+Right, you will get the possibility of searching through the results. But, let's take searching for selectors as an example of how to tweak Spotter to search for what you want. Install this method in your image and try searching with Spotter again. It's ugly, but it is working :): GTSpotter>>spotterSelectorsFor: aStep <spotterOrder: 0> | processor | processor := aStep listProcessor. processor title: 'Selectors'; filter: [ :originalQuery :stream | |query selectors | query := originalQuery trimBoth asLowercase. query isEmpty ifFalse: [ selectors := Set new. SystemNavigation default allBehaviorsDo: [:class | class selectorsDo:[ :selector | ((selectors includes: selector) not and: [ selector beginsWith: query ]) ifTrue: [ selectors add: selector. selectors size > 5 ifFalse: [ stream addObject: selector inProcessor: processor ]]]]. selectors ] ]; actLogic: [ :each | self systemNavigation browseAllImplementorsOf: each ] -Only shows me 5 (implementation) results at the time. > You can actually dive into those results and refine the search. If you press Cmd+Shift+RightArrow you will get all the results in the category. We know that this feature is not well offered and we will work on making it more obvious.

Do you mean the preview of sources? If yes, you should take the latest version of Pharo and take a look again.

What should be done to make this work on OS X? UnQLiteFFI>>libraryFileNameForPlatform has a wrong name, but that doesn't help me. Even after renaming the library cannot be found. Stephan

Tagging packages
by Laura Risani Feb. 13, 2015

Feb. 13, 2015

Hi all, What method do you use to organize/tag your packages so you can then easily retrieve those sharing a same tag? Is there any functionality intended for it? I've been trying the following ones (ordered by increasing satisfaction): prefixing, flagging, sharing repository, pragma. But i feel like none of these achieves a proper balance (for package tagging) between ease of retrieving, persistence and conceptual coherence/cleanness (at least in the way i've been using them, perhaps i ignore something). Love, Laura

libssl on fedora to new for pharo-vm
by Martin BÃ¤hr Feb. 13, 2015

Feb. 13, 2015

hi, i just discovered that i can't make https requests in pharo because pharo-vm tries to link against libssl.1.0.0, but recent fedora versions have libssl.so.1.0.1e at least since fedora 18 i did discover that the centos version on http://files.pharo.org/vm/pharo/linux/centos/ works however. i wonder if that shouldn't be linked more directly from the download page... greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.se caudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.org realss.com unix sysadmin Martin BÃ¤hr working in china http://societyserver.org/mbaehr/

Re: [Pharo-users] Writing a Login Dialog using Spec in 3 methods
by Stephan Eggermont Feb. 13, 2015

Feb. 13, 2015

In order to not get results like the extent and width should be calculated values. That would change the example code to something like LoginModel class>>defaultSpec <spec: #default> ^SpecLayout composed newColumn: [ :col | col newRow: [ :row | row add: #usernameLabel width: self labelWidth; add: #usernameField ] height: self inputTextHeight; newRow: [ :row | row add: #passwordLabel width: self labelWidth; add: #passwordField ] height: self inputTextHeight ]; yourself LoginModel class>>labelWidth ^((StandardFonts defaultFont widthOfString: 'Password') max: (StandardFonts defaultFont widthOfString: 'Username'))+12 Please note that there are still several places in Spec where hardcoded values like 12 are used instead of semantic values. This value should actually be dependent on font size. Having the label texts twice in the code should also be avoided. LoginModel class>>textFieldWidth ^(StandardFonts defaultFont widthOfString: 'longest.email(a)addressThatShould.fit')+12 LoginModel>>initialExtent ^(3*12+self class labelWidth+ self class textFieldWidth) @ (5*self class buttonHeight) There are several calculated values missing: width = outside border + labelWidth + label field separator+fieldWidth+outside border height = dialog title + textInput height + separator + textInput height+ separator+button height + outside border Stephan

Changes file size
by Esteban A. Maringolo Feb. 13, 2015

Feb. 13, 2015

I know we're on our way to get rid of changes, but meanwhile after installing my Metacello config I end up with an image of 40megs and a changes file of 140 megs!!! It doesn't load anything too esoteric: Glorp, Magritte, Seaside, Postgres, NeoCSV and my own packages. I can run PharoChangesCondenser condense, but it takes forever! (I started it 20 minutes ago and it's still running). Is there a way I can improve this situation? Esteban A. Maringolo

The current implementation. It is a significant barrier to entry for new smalltalkers and gives a very bad impression. The epicea swap is a high-impact change, that is likely to affect stability for some time. Stephan
