Is there a way to display Spec widgets in a ListModel?

by Julien Delplanque

Hi everyone, I can't find how to display Spec widgets in a ListModel, is it possible? I would like to have a list model holding, at each row, a TextModel and a ButtonModel. Thanks in advance, Julien

Re: [Pharo-users] CMD/CTRL-B for browsing?

by Stephan Eggermont

The 'code' related behavior is currently too fixed to smalltalk code only. I want to be able to edit Pillar, PostgreSQL, user stories etc. Shortcuts for doIt, browse, senders, implementors etc. make sense for these environments, but need a different implementation. And sometimes I'm editing text where the code shortcuts do not make sense. When inspecting a symbol, I expect code related shortcuts, because they are commonly used in meta programming. Stephan

No, just the fact that the IR is quite complex (have a look into the llvm IR reference), so you use a context and a builder (Builder.CreateFAdd) in the C++ code (and I think the Ocaml llvm module is probably large since it recreates the structure). The naming scheme of LLVM is quite complex and unobvious as well (the %0, %1, etc...) with strange rules biting you if you don't number the same way as LLVM does when you use its API.

I am a co-heretic with Doru. In domain-specific languages built on top of Pharo you are faced exactly with what Doru is saying. I see these issues in my work on Live Robot Programming (and stuff before that).
