We're using it in a commercial project on Pharo 1.4 SE, it installed with no issues :) What problem are you having? 2012/11/3 StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> > I know that hilaire is using it but I do not know who is maintaining it. > > Stef > > On Nov 2, 2012, at 11:28 PM, Chris wrote: > > > Hi All, > > > > Is anyone maintaining the above package?

The proper idiom to use is FileStream readOnlyFileNamed: 'C:\test.txt' do: [ :stream | â¦ ]. or in Pharo 2.0 'C:\test.txt' asFileReference readStreamDo: [ :stream | â¦ ]. 'C:\test.txt' asFileReference writeStreamDo: [ :stream | â¦ ]. HTH, Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

stream usage in workspace

by Ben Coman

I am refereshing my familiarity with streams by looking at PharoByExample1 which says... "You have to remember that each time you open a stream on a ï¬le, you have to close it too." Does that mean if in Workspace I iteratively develop some code to process a stream, so that I am continually running... myStream := FileStream readOnlyFileNamed: 'C:\test.txt. ...so that 'myStream' is overwritten each time such that I lose reference to the previous stream, and I am no longer able to send #close to it, am I creating a memory leak in my image ? My prior assumption has been that once 'myStream' drops the reference drops to the previous stream, garbage collection would take care of 'everything'. cheers -ben

Gettext in Pharo 1.4

by Chris

Hi All, Is anyone maintaining the above package? I had a few issues when trying to use it in Pharo 1.4 Summer but have done a few fixes and it is now working well for me; would like to run them by someone who knows a bit more about it first. Thanks Chris

Acquiring lock, releasing in callback

by Sebastian Nozzi

Hello Dear Pharo users, threads and co. are giving me headaches :-) I wanted to ask for advice... What do I use in Pharo to prevent more than one thread entering a region, but "releasing" the exclusivity in another block/callback? For example, let's suppose there is an hypothetical class "Lock" that does that. lock acquire. longOperation performWhenFinished: [ callback code ... lock release ]. ... rest of the program ... Is there something like that? Or do I have to simulate it with something else? (Semaphore?) I am aware or Monitor/Mutex critical:, but I am not sure I can use it in my case. Thanks in advance, Sebastian

Re: [Pharo-users] [OT] RTalk

by dimitris chloupis

yes I thought I made this clear in my first post, the reason why I find RTalk so tempting is that it does not only offer the language but also the environment which AFAIK redline does not. Please correct me if I am mistaken, but I have not seen redline docs/wiki mention the enviroment anywhere and I have to say that smalltalk environment is pretty much the reason why I chose smalltalk and not so much the language. ________________________________ From: Geert Claes <geert.wl.claes(a)gmail.com> To: pharo-users(a)lists.gforge.inria.fr Sent: Tuesday, 30 October 2012, 12:54 Subject: Re: [Pharo-users] [OT] RTalk for Smalltalk on the JVM there is Redline Smalltalk I thought ...

[OT] RTalk

by dimitris chloupis

I found this http://www.jarober.com/blog/blogView?showComments=true&printTitle=IM_98:_Rt… ,about RTalk , that is not only smalltalk run on top of JVM but almost the entire environment.Â The problem is that I cant seem to be able to find via google any site that contains the source code or something I could use ? Does anyone know if there is any official website for RTalk ? It looks quite promising and I would like to give it a try.

I'll keep the daily timeout, although I'll write "1 day asSeconds" because... well isn't that why we love Smalltalk ;) Thanks again, Sean -- View this message in context: http://forum.world.st/Zodiac-long-term-streaming-tp4653138p4653159.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
