[Pharo-users] ImageWorker error in P6.1

Hello! The ImageWorker project, that provides the possibility to fork a OS process with a copy of current image, was working fine in Pharo 60400 but it's not working on latest 6.1. The output there is "External Image Failed: 256". Any hint? Steps to reproduce error: 1. download: curl get.pha

Re: [Pharo-users] canonical way to convert Symbol into Class (retrieve class by its name)

Agreed! In that case denis we should add a bug entry and clean the complete image. And no asClass sucks and we do not want to use thisContext. Why can we do simple thing and avoid to add more accidental complexity. Stef On Sat, Feb 10, 2018 at 7:18 PM, Denis Kudriashov wrote: > > 2018-02-10 20:

Hi Siemen I use often cmd-L too and may be we got a regression. And indeed I have the same behavior in Pharo 70. Can you try to see how to address it? Stef On Fri, Feb 9, 2018 at 8:37 PM, Siemen Baader wrote: > Hi all, > > I downloaded Pharo 6.1 for OSX and whenever I revert changes in Nautilus

Hi Clément, First time I read about modules in Pharo. What is a module exactly? What's the problem to solve? Cheers, Hernán 2018-02-10 9:47 GMT-03:00 Clément Bera : > Hi, > > In short, everything that is not namespace/module compatible will be > deprecated/changed/removed in the future, so it i

Re: [Pharo-users] canonical way to convert Symbol into Class (retrieve class by its name)

Modules can import other modules to be able to use their classes directly. Anyway, this is theory, there is no module implementation currently. But the idea in the recent versions of Pharo (5-6-7) was to start moving away from things like (Smalltalk at: #className) or (#className asClass) since i

Hi, In short, everything that is not namespace/module compatible will be deprecated/changed/removed in the future, so it is not recommended to use it. a.2) #Array asClassInEnvironment: Smalltalk globals b.1) Smalltalk globals at: #Array => Ok-ish, note that you may need to change 'Smalltalk globa

Peter, I have no answer for you as I am not a Pharo expert. It may be part of an answer to your question "why?", however. I think most if not all of the alternatives you mention are equally good as long as you assume there is only one place to look for Classes. As soon as you introduce namesp

Hi, what is the canonical way to get a class from a symbol? a) Converting symbol into class via string protocol a.1) #Array asClass I use this the most, because it is easy, uses unary selector, and so far I've never ran into any issues. But apparently it is not good -- why? a.2) #Array asClassI
