I'm trying to get pharo and teapot working with Docker. I've downloaded the command line image and I see a lot of Docker images but I'm not quite clear on how to connect the parts... Tony Giaccone

Re: [Pharo-users] Syntax Error: Message pattern expected

by Johannes Brauer

Hi Ben, hi Alistair! Thank for your adjustment. In the meantime I looked backward in the version history and I found an older version which I can load without problems. Then I looked at the changes of the next higher version (producing the syntax error) and I found the following problem: [cid:54AA1677-A657-46E1-BAEF-E4AD0236C463@Speedport_W_503V_Typ_C] Indeed, there is no message pattern, I have not a clue how something like that can happen.

Re: [Pharo-users] How to load a baseline in Iceberg? Get #addTo: sent to nil?

by Tim Mackinnon

Alistair - does that mean youâve not tried using that menu item on a baseline package? I think its there for this reason - but maybe Esteban will comment when heâs back from holiday. So on a related front - do you go to a separate workspace and type in Metacello new baseline: âMyBaseline'; repository: 'filetree://./local-project/src'; load. ?

I don't know the original intent, but I've never thought about Iceberg this way. My understanding is that baselineOf: is intended for use by metacello. Iceberg allows you to load individual packages, but it's focus area is code development, not package loading. I use Iceberg to load the baseline package, edit it, then save it back to the git repository, then load the entire project through metacello (usually in separate images so I'm testing in a clean environment).
