CodePharo
by Esteban A. Maringolo Nov. 19, 2013

Nov. 19, 2013

Firefox foundation just released a curriculum to get developers acquainted with the process of contributing to Firefox. Which itself guides in the completion and extension of it. http://codefirefox.com/ I know there are some videos guiding Pharo contributors in the process of reporting bugs, submitting patches, etc. It could be great if we could mimic the CodeFirefox initiative with a CodePharo one. I know this requires time, but I shoot the idea to this mailing list, maybe somebody is willing to give it a try, or at least park the domain (or subdomain code.pharo.org) Regards! Esteban A.

Transcript and ScaledDecimal Issue
by phil＠highoctane.be Nov. 19, 2013

Nov. 19, 2013

I was playing with ScaledDecimal when doing experiments with numbers in Pharo. Now, ScaledDecimal says in its comment: "Note that a ScaledDecimal does not printOn: exactly, however it will storeOn: exactly because the full precision fraction is kept in memory." This happens to be right when inspecting the expressions. Now, I tried to do the following: x := 2 asScaledDecimal. y := 1 asScaledDecimal. z := (y / x). z storeOn: Transcript. And z storeOn: Transcript fails miserably. This is due to storeOn: doing: storeOn: aStream "ScaledDecimal sometimes have more digits than they print (potentially an infinity). In this case, do not use printOn: because it would loose some extra digits" self shouldBePrintedAsLiteral ifTrue: [self printOn: aStream] ifFalse: [aStream nextPut: $(; store: numerator; nextPut: $/; store: denominator; nextPut: $s; store: scale; nextPut: $)] And store: doesn't exists in the ThreadSafeTranscript which happens to be no stream at all. Try this out: x := 2 asScaledDecimal. y := 1 asScaledDecimal. z := (y / x). "works" 5.0 storeOn: Transcript. Transcript flush. "works" (1/2) storeOn: Transcript. Transcript flush. "fails" z storeOn: Transcript. Transcript flush. "works" s := (String new: 30). st := s writeStream. z storeOn: st. Transcript show: 'storeOn: ', st contents; cr; show: z. Kind of annoying to do while explaining to kids. The ThreadSafe transcript looks like to be subclassed from Object and being no real stream at all. Why is it so? Phil

SVG described countries in Roassal
by Alexandre Bergel Nov. 19, 2013

Nov. 19, 2013

Hi! I had fun understanding how countries may be described using SVG. Here is a first shoot: Moving the mouse above a country name highlight the country. You can now rehearse your geography. The complete source code of this example is: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | view element nameComponent label | view := ROView new. ROSVGPath countries do: [ :k | element := (ROSVGPath path: (ROSVGPath perform: k)) elementOn: k. view add: element. ]. nameComponent := ROElement new. ROSVGPath countries do: [ :k | label := ROLabel elementOn: k asString. label @ ROLightlyHighlightable. label on: ROMouseEnter do: [ :event | ROBlink highlight: (view elementFromModel: event model asSymbol) ]. label on: ROMouseLeave do: [ :event | ROBlink unhighlight: (view elementFromModel: event model asSymbol) ]. nameComponent add: label. ]. ROGridLayout new gapSize: -3; lineItemsCount: 15; on: nameComponent elements. view add: nameComponent. nameComponent translateTo: 0 @ 400. view openInWindowSized: 1000 @ 700 -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

SHTextStyler>>#styleInBackgroundProcess:
by Sven Van Caekenberghe Nov. 19, 2013

Nov. 19, 2013

In many images that I do real development in (code writing, debugging, ..) I always get a number of processes stuck while waiting for a semaphore in SHTextStyler>>#styleInBackgroundProcess: I am in no way an expert in these areas, but today I tried the following change (waiting on the semaphore with a timeout): SHTextStyler>>#styleInBackgroundProcess: aText self terminateBackgroundStylingProcess. stylingEnabled ifTrue: [ text := aText copy. self monitor critical: [ sem := Semaphore new. [ sem ifNotNil: [ ((sem waitTimeoutMSecs: 250) not and: [ view notNil ]) ifTrue: [ view stylerStyledInBackground: text ] ] ] forkAt: Processor activePriority. backgroundProcess := [ self privateStyle: text. sem signal ] forkAt: Processor userBackgroundPriority ] ] Comments ?

Fwd: [Pharo-bugtracker] FogBugz (Case [Issue]9) _Inbox - Back In Town
by Sven Van Caekenberghe Nov. 19, 2013

Nov. 19, 2013

Among the many messages sent automatically by our magic systems, this one strikes me as useless. It basically says that the monkey is doing something, without being specific: no issue number, nothing.

class HTTPSocket
by Sven Van Caekenberghe Nov. 19, 2013

Hi, HTTPSocket (which is only a facade) was deprecated in 2.0, so I guess it could be completely removed in 3.0 ? Sven

Re: [Pharo-dev] [Moose-dev] I'm not getting it
by Tudor Girba Nov. 19, 2013

It's not Moose related, but Athens related. There seems to be a problem with Athens and your Linux installation. I repost the question on the pharo mailing list. Anyone has an idea why this happens? Moose 4.9 runs on a Pharo 2.0 image. Cheers, Doru On Tue, Nov 19, 2013 at 12:22 PM, Friedrich Dominicus < frido(a)q-software-solutions.de> wrote: > I've a fresh installed Moose 4.9 here.
