Hi, The revert of changes of Spec 1 is now done in Pharo 8. Spec 1 is now in the same state than in Pharo 7 and Spec2 can live next to it. All classes of Spec2 start with the Sp or TSp prefix.

resetting iceberg

by Steve Quezadas

I was playing around with the settings of iceberg and I must have messed up a setting or something because now when I open iceberg, I get a "object not found - no match for id". Is there a way to "reset the settings" of iceberg so I can at least open it back up? - Steve

Re: [Pharo-users] [Pharo-dev] [ANN] Pharo Headless - Beta (Actually what is between Alpha and Beta)

by tesonep＠gmail.com

Hi, The executables are not the same. We have 2 different now: the Stock VM (that is downloaded by the launcher, and it is the default download in Zero-conf), and the headless VM (this is downloaded by zero-conf when using vmLatestHeadless). Those platforms are not representative we currently have: OSX, Windows, and Linux all 64bits. We are working in ARM 32bits. In the near future, I will work on validating different flavors of Unix, but again It depends on the roadmap, and they are not there now. If someone requires some other platform we can talk to see how it can fit in the roadmap. Cheers, Pablo On Mon, Aug 12, 2019 at 10:03 AM Tudor Girba <tudor(a)tudorgirba.com> wrote: > > Hi, > > Yes.

Hi Doru, can you give us more insight of the errors? Because there should not be changes in the behavior of the VM. Maybe there are issues, we have used the Pharo tests as a guarantee and we are laking some tests. Cheers, Pablo.
