Re: [Pharo-users] A bit of collection magic

by Bernhard Pieber

I normally do this with two nested #do: calls: Array streamContents: [:stream | #(a b) do: [: i | #('one' 'two' 'three') do: [:j | stream nextPut: (i , ' matches ' , j asString)]]]. However, it may well be that there some method like this in Pharo or some external package on SqueakSource.

Re: [Pharo-users] **Important Please read** Towards First Class Tasks

by StÃ©phane Ducasse

Hi guys I'm in town. Now I want to make clear the following: This idea is much more on having an effort to collect todo and manage to kill some of them regularly than to engage to for long task. As an example for the UI I would like - layout fixed so that glamour IDE can work - in place edit in list items (for example to be able to directly edit the protocol of a method in a sender list) - an option to get list showing only elements matching an input on the fly What you see is that we should have list of "simple" tasks that people can sign in for. The idea is that we should coordinate a bit to make progress.

A bit of collection magic

by Bernat Romagosa

Hi list, I'd love to have something like: #(#a #b) combinationsWith: #('one' 'two' 'three') collect: [:i :j | i , ' matches ' , j asString] That returns the collection: #('a matches one' 'a matches two' 'a matches three' 'b matches one' 'b matches two' 'b matches three') In other words, is there some kind of vectorial-product-like method for collections in Smalltalk? Thanks! Cheers, -- Bernat Romagosa.

Hi Mariano, thanks, you found the problem. Remove category in the browser does not really remove the package; if i open monticello an empty package is still there. if i remove it in monticello the configuration works as advertised <g>. werner

You scenario looks a little tricky. Why did you use package-cache as the repository? is that what you really want?

Re: [Pharo-users] detecting and reacting to a race condition/infinite loop

by Werner Kassens

Hi Paul, and everytime you made a coffee and then you went back to your computer it has rebooted, since the ui-interface noticed it was in an infinite loop waiting for your input <g>. but its generally not really possible. consider an object that has a variable i and these 4 methods: Counter>>initialize i:=0 Counter>>inc i:=i+1 \\ 42 Counter>>count 200 timesRepeat: [self inc] Counter>>dumb [self inc. i<50]whileTrue it would not be sufficient to store the state of _all_ variables, the moment one var changes, it would not be sufficient to store the state of the program at this moment (iow that it is in method inc when i gets set to the same value), you would also need to store the history of the program states (iow that it comes from method dumb). werner

Re: [Pharo-users] metacello question

by Werner Kassens

i tried spec group: 'Core' with:#('Pattern') with (ConfigurationOfPattern project) latestVersion load and with load:'Core' with the same result. i did not define a version for Nile in version10, but that should not make a difference for my problem, as there is a definition in the baseline, right? werner

Re: [Pharo-users] metacello question

by Paul DeBruicker

Depending on how you load your configuration you might need a line in the baseline that says: spec group: 'Core' with:#('Pattern'). Then try (ConfigurationOfPattern project) latestVersion load or if you've defined #stable: ConfigurationOfPattern load Also in your version10 method do you define what version of Nile you want to load? -- View this message in context: http://forum.world.st/metacello-question-tp3648875p3649112.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hapao installation

by Romain Verduci

Hello, I tried to download Hapao in Pharo 1.2.2 with the code in the Hapao website : Gofer new squeaksource: 'Spy'; package: 'ConfigurationOfSpy'; load. (Smalltalk at: #ConfigurationOfSpy) perform: #loadDefault When I load the packages, there is a dependency with SubscriptionRegistry package, what is this package ? Finally, when I want to run Hapao in the Pharo menu, there is the following message: MessageNotUnderstood: PluggableDialogWindow>>beResizeable. In fact this message does not exist in the system, is it because of SubscriptionRegistry package isn't load ? Or because I did something wrong ? Thanks for answers. Romain
