Hi, Here is a first idea of how to do it : image := (ZnEasy get: 'http://www.w3schools.com/css/paris.jpg') contents. file := 'file.jpg' asFileReference. [stream := file writeStream. stream nextPutAll: image. ]ensure: [stream close]. ImageReadWriter formFromStream: file readStream.

Done: 19441 <https://pharo.fogbugz.com/f/cases/19441/Better-description-for-MessageNotUn…> . I also change nil case to "message was send to nil" (instead of "receiver of message is nil").

Drastically improving the messageNotUnderstood title

by stepharong

Hi guys As I exposed newbies to our wonderfull debugger I think that we should change MessageNotUnderstood: Class>>#message into an instance of Class did not understand message To me this simple change would have a HUGE impact on making the debugger first contact a lot more friendly. Any taker? I'm off with a company today. Stef --

Re: [Pharo-users] [squeak-dev] pondering Smalltalk scripting in Minecraft

by Ben Coman

Thanks Sven. I completely missed that. However digging in, it seems only the Pi version got an API. The PC versions have no official API, although Forge seems to be the default community one by reverse engineering the obfuscated libraries each time Minecraft is released. Dimitris, thanks for the reminder of Redline Smalltalk. That seems a good candidate for running Smalltalk from a Java application. [I'm finding it tedious with Scriptcraft that every time I edit a source file I need to invoke refresh() ]. cheers -ben On Wed, Dec 7, 2016 at 4:46 PM, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > Have you seen this: > > http://forum.world.st/ANN-Minecraft-Bindings-tt4671908.html > >> On 7 Dec 2016, at 09:40, Ben Coman <btc(a)openinworld.com> wrote: >> >> Minecraft is immensely popular.
