Re: [Pharo-dev] [Pharo-users] Pillar 1.1.0 released

by Johan Brichau

Hi, I just noticed that in the most recent version of Pillar, the instvar #embedded was removed from PRReference This breaks Pierâ¦ though right before this change I could make Pier3 work with Pillar just fine. The embedded var is used to specify that component references are to be embedded in the page. There are more components than Figures in Pier. I am just trying to use and work with Pier3 for Seaside book and website, so it would be great if you can consider adding the embedded variable again. thanks guys!

call "compress file " from the FileList

by Nicolai Hess

There was a bug on compress file (see issue https://pharo.fogbugz.com/f/cases/10235/StandardFileStream-compressFile-can… ) This is fixed know for Pharo 4.0, anyone knows why we can not call "compress file" anymore in Pharo 5.0 ?

On the other hand, we now have this failing test (skipped for windows), so maybe I will remove the test. But still, I would like to know if this change was by accident or on purpose.

Nothing has changed, the linux example still don't work and I can not get information about who maintains the unix-examples. >From my analysis (see above), the fix may be simple (in another discussion around that time some one else asked how to make that working, and confirmed it works with that fix). But I am confused because the latest update for the examples had the comment "made the XLib examlpes actually work". So maybe my usage or version of FFI is wrong. The last time I asked, someone said this works for him with the current stable vm, but it was actually the latest cog vm he used. But now, a year later, with the current 4.6 cog and 5.0 spur vm, some FFI unit tests still failing so maybe I am using the wrong FFI package (FFI-Kernel-EstebanLorenzano.27) ?

What we could do (maybe this is a bit overkill): - make an announcements hierarchy (NautilusPackageAnnouncement -> NautiulusClassAnnouncement ...) but never subscribe to this Announcemnts - create sub classes for every "kind" NautilusPackageAnnouncement subclass: NautilusPackageChangedAnnouncement NautilusPackageAnnouncement subclass: NautilusPackageSelectedAnnouncement NautilusClassAnnouncement subclass: NautilusClassSelectedAnnouncement NautilusClassAnnouncement subclass: NautilusClassChangedAnnouncement And only subscribe to this subclasses.
