[ANN] Pharo 5.0 released!
by Esteban Lorenzano May 14, 2016

May 14, 2016

Hi, Please spread widely, and sorry for multiple posts. (this post can be see here: http://pharo.org/news/pharo-5.0-released <http://pharo.org/news/pharo-5.0-released>) Dear World, The time has come for Pharo 5.0! This is our most significant release yet. Here are some highlights: - The PharoVM is now based on Spur, the new memory management, and it brings with it a 35% speedup! - A new unified foreign function interface (UFFI) replaced NativeBoost to provide a strong Spur-compatible framework for interfacing with the outside world. - The Glamorous Toolkit now includes the GTDebugger to offer a moldable infrastructure that allows the developer to customize the debugger deeply. - The underlying Reflectivity mechanism has reached maturity with multiple pieces coming together to empower developers to instrument their own systems. For example, we now have breakpoints implemented as just a simple extension of this mechanism. - QualityAssistant is now part of the image to provide live feedback during development. These are just the more prominent highlights, but the details are just as important. We have closed 2446 issues in Pharo 5. Take a moment to go through a more detailed recount of the progress: https://github.com/pharo-project/pharo-changelogs/blob/master/Pharo50Change… <https://github.com/pharo-project/pharo-changelogs/blob/master/Pharo50Change…>. While the technical improvements are significant, just think of getting 30% faster out-of-the-box, still the most impressive fact is that the new code that got in the main Pharo 5.0 image was contributed by 100 people. Together we have touched 43% of the classes, and 20% of the methods. The following visualization rendered with Roassal in Pharo 5.0 is dedicated to this effort. The picture shows the touched classes and packages in gray, the authors and the links to the changed classes in red, and, using an automatically generated visual id, you can spot authors that have worked on similar projects. Pharo is more than code. It is an exciting project involving energetic people.

Re: [Pharo-users] Week number from a date
by CÃ©drick BÃ©ler May 12, 2016

May 12, 2016

Not sure it exists (I didnât find it but it may exists)â¦ so I did a quick try to code a new method in the class Week. There is already index but this method returns the index of the current month. I did something like below (not tested much): Week>>yearIndex ^ (self dayOfYear / 7 + 1) asInteger ==== DateAndTime now asWeek yearIndex returns 19 Maybe it would be better to create an equivalent method (weekYearIndex) in Date (or eventually Timespan). hth, CÃ©drik

Semaphore wait and signal
by Vince Refiti May 12, 2016

May 12, 2016

Hello I am playing around with Semaphore, and wrote the following: | coll count sem | coll := Array withAll: (1 to: 100). count := 0. sem := Semaphore new. coll do: [ :each | count := count + 1.

Also the entire statement paused for 2 seconds, spat out some lines, then waited a little longer, and then finished. Can someone please explain this pattern? Thanks, Vince

OrderedCollection get all lines
by Valentin Ryckewaert May 11, 2016

May 11, 2016

Hi, I would like to reproduce the grep command in Pharo. To do it I wanted to get the content of a stream and transform it to an OrderedCollection (to use matchesRegex: on it). First of all, is there an easier way to do it? In a second time, is there a method to get the content of a Stream as an OrderedCollection ? (nextLine exists so I could use it to get my OrderedCollection but is there an easier way?)

Temporary files
by Valentin Ryckewaert May 11, 2016

May 11, 2016

Hello everyone, I would like to use a temporary file for a project and I didn't find an existing method. I'm asking my self if it's a better idea to use ffi or OSSubProcess (or something already build for it) to build a method able to create this tmp file. Someone could help me please? PS : Should it be a good idea to add this method directly in Pharo ?
