"In Pharo1.4 #14439... The following changes the working directory as far as FS is concerned" FileSystem disk changeDirectory: '..'. "As confirmed by..." FileSystem disk workingDirectory. "But the system's default directory has not changed, as seen by" FileDirectory default "and must be changed by..."

[Pharo-project] PDF4Smalltalk (was: Artefact - a PDF framework)

It's a bit of a hurdle to download, install, refresh/update VW skills - just to evaluate some code. (When I first heard you'd decided on GIT, I briefly thought that Dale's Montecello/GIT would let me browse the code easily - maybe this will be true, at some future date).

PDF4Smalltalk is a system library providing full access to PDF. PDF objects are regular Smalltalk objects which you can read from PDF files or create them with code and write them as PDF. The PDF basics are quite complete and robust (I use it for a few years in production now), but there are also lots of features desired :-) (TrueType fonts and bitmap images to name a few). It deals purely with PDF and does not add any higher concepts like tables and other layouting facilities - in fact not even proper classes for graphics or text... (high on my list when I find time). It is like painting on a canvas: you are completely responsible for the placement of everything. To deal with that, Bob Nemec implemented Report4PDF which uses Seaside like layouting for a report generator. It is done, works and is quite nice! See http://smalltalk-bob.blogspot.de/2012/01/pdf-report-and-law-of-demeter.h tml I'd love if someone would port this to Pharo! I would help with answering questions, but I have not time to do anything substantial in the moment... Cheers, Christian

[Pharo-project] cmd-dot is being temperamental in 2.0
by Francisco Garau May 2, 2012

May 2, 2012

Hi - on a fresh Pharo 2.0 image (build 20041) open Nautilius and press cmd-dot: the usual User Interrupt debugger will appear. Close the debugger and click one of the Nautilius packages and press cmd-dot: nothing happens. Open a new Change Sorter window, go back to the previous Nautilius browser and cmd-dot works again. This is on Mac running OSX 10.6.8. The issue is reported in: http://code.google.com/p/pharo/issues/detail?id=5766 - Francisco

[Pharo-project] [newbies] How to move submorphs
by Martin Drautzburg May 2, 2012

May 2, 2012

Hello all, I have an infinite ribbon, which represents time. In the ribbon there are submorphs which represent activities with a start and an end time. They have a model (think: gantt chart) I want to move those submorphs around with the mouse or lengthen or shorten them at their edges. To do this I want to change their models. The trouble is: only the ribbon itself knows how to translate geometry into time and vice versa. The "activity" Morphs know if the mouse is over one of their edges (for resize) or in the center (for move). So I really need to let the ribbon alter the activity models. But how can the ribbon know, which activity the cursor is over? I kind of want the activitiy Morphs to talk to the ribbon saying: "okay the curser is over my left edge, it is starting a mouse move, now you (ribbon) go ahead and change the start time of my model". How do the big boys do this? -- Martin

[Pharo-project] One month working for Pharo Consortium
by Esteban Lorenzano May 2, 2012

May 2, 2012

Hi, So, I'm working since one month for Pharo Consortium, and I want to talk a bit about how is life here, in RMOD headquarters... Of course, is obvious to say that, so far, is been a great experience, and a lot of fun... the team here is great, very capable, focused and always willing to help (and to hack something, he). In one month, I already face a lot of different issues: 1) I helped on release 1.4: - lots of bugfixed and reviews integrated. - finishing and integrate new ecompletion/ocompletion - integration of FileSystem - fixing VM important issues in windows (FFI plugin and command line options) 2) I worked on the new release process, both in defining them and in doing steps to make it happen (still far from there) 3) Tried to took off some pressure from Marcus and Stef shoulders... I failed miserably in this issue, because they (both of them) are more or less workaholics and really enjoy what they do, so, take some of their responsibilities is not to easy :) 4) I also made some small steps on the upcoming pharo consortium web site. Well, more or less, that's all. Could I make more? Probably, but well, I was just adapting to a new country, a new language and a new work environment. In my not-so-good list, my responsibilities includes the bootstrap of the pharo consortium, and I think that's the biggest missing in the month work. I will try to fix that next month. In my TODO list, now there are: -bootstrap consortium site -make a first iteration on new release process -make some "experiments" on validating configurations -tackle issues and integrate them :) best, Esteban

I'm taking some times to go back the block closure chapter and I was wondering how I can get access to block temporaries [ |a | a :=2. a] for example I tried [ |a | a :=2. a] outerContext contextForLocalVariables tempAt: 1 and variations but none worked. Stef
