[ANN] Pharo 6.1 (summer) released!

by Esteban Lorenzano

Hi, We are releasing Pharo 6.1. Usually, between each major version we just apply bugfixes changing the build number and not announcing new versions but this time is different since the fixes applied required a new VM. The principal reason for the new version is to update Iceberg support, bringing it to macOS 64bits version. So, now Pharo 6.1 comes with Iceberg 0.5.5, which includes: - running on macOS 64bits - adds cherry pick - adds major improvements on performance for big repositories - adds pull request review plugin - repositories browser: group branches by remote - adds bitbucket and gitlab to recognised providers on metacello integration - uses libgit v0.25.1 as backend - several bugfixes Other important change: - linux vm by default is now vm threaded heartbeat. We still miss 64bits Windows (sorry for that), but we are getting there. I hope to have it running right after ESUG. To download 6.1 version, you can go to http://pharo.org/download <http://pharo.org/download> page, or with zeroconf: wget -O- get.pharo.org | bash Enjoy! Esteban

LargeInteger is not what you should use. Try this: v:= SmallInteger minVal - 1 In 64-bit, one gets:"-1152921504606846977" and there you have a LargeNegativeInteger that prints properly. v := SmallInteger maxval + 1 "1152921504606846976" same but positive. You have Integers that are Numbers and why bother with the large or small thing? It works. If things are getting slow, well, profile and optimize.

Question

by Koos Brandt

Hi I am still learning but something weird happened. In a new Workspace Do-it myVar := LargeInteger new Print-it myVar <error in printString: try 'Inspect it' to debug> When I inspect it I get SubclassResponsibility: LargeInteger had the subclass responsibility to implement #printOn:base: When I browse LargeInteger, then at Integer level I get a message ânewâ as follows: new self == Integer ifTrue: [ ^ self error: 'Integer is an abstract class. Make a concrete subclass.']. ^ super new I looked for new higher up in the hierarchy(super), but could not see it. Maybe I am a bit dumb still with looking up. I tried on SmallInteger a new, but got back Error: SmallIntegers can only be created by performing arithmetic. I then checked and noticed that SmallInteger actually have new and basicNew implemented (override) So the error I got on smallinteger was from the override LargeInteger has no override, but has a âsilent" error This seems a bit weird to me Just so you know I also tried Do-it myVar := LargeInteger new: 10000 Print-it myVar class. -> LargeInteger Dot-it myVar := myVar + 1 The last statement hangs the image! (Tried 3 times) Comment: 1. I am surprised that Do-it did not give me an error on the new: (there is a message is the hierarchy of new:neg and maybe the neg is optional?) 2. The new: seemed to have created 10000 LargeIntegers 3. I tried the new: also with just 5, and same result, image hang. (I thought 10,000 was maybe a very large loop for the + 1..) Did I damage something in the image maybe? I started this one just yesterday to look at MOOC week1. I do not need LargeIntegers for now but â¦ This is Pharo 6.0 64 Bit on Mac OSX Sierra 10.12.5 (iMac 27, 2.9GHz Intel Core i5, 16GB RAM) Regards Koos Brandt 0824542028

Entered https://github.com/jigyasa-grover/CORMAS-Pharo.git as the URL 4. Left the subdirectory blank (opening the repository in a browser you can see that the packages are in the top level directory) 5. Clicked Create repository 6. Selected the repository, the packages tab and loaded the ConfigurationOfComas without any problem. Pharo 6.0 Latest update: #60501 Is there an easy way to tell which version of Iceberg I have loaded? I'm sure it is 0.5.x, but not what the x is. Cheers, Alistair

Hi, in fact, I think you made quite the contrary: you declared a code subdirectory that does not exits. what you need to do is to press âEditâ¦â button and clean anything that appears in âcode subdirectoryâ field. also, I have no idea why you have two entries for same project :) Esteban > On 23 Jul 2017, at 23:22, HernÃ¡n Morales Durand <hernan.morales(a)gmail.com> wrote: > > Hi guys, > > I am trying to import code - in Pharo 6 - from a GitHub repository: > https://github.com/jigyasa-grover/CORMAS-Pharo.

Re: [Pharo-users] Why do we separate class/instance methods in the browser?

Its very jarring > and breaks your flow to âswitch modeâ to type one in. You raise an important issue here. At the time of subclassing, we separate variables into instanceVariableNames and classVariableNames, but not with method selectors :-(. Separate tabs or panels (instance, class) may be a better way to display these methods. This quirk pops up in textual mode too. "Foo" alone refers to a class but "Foo>>bar" refers to a instance side method and we have to use "Foo class>>bar" to refer to the class side method. Regards .. Subbu
