Hi Roelof, I remember about a Smalltalk book presenting the CRC concept precisely used to cut complex problem in small chunks. I can't find the reference right now but it is very likely among those books available online (http://stephane.ducasse.free.fr/FreeBooks.html) May be a member of the list remember about it.

Testing Baselines Modifications
by Vitor Medina Cruz April 24, 2020

April 24, 2020

Hello, How do you usually test Baseline modifications? I have a separate image with my git project added and when I need I load it with Metacello to see if everything works correctly, but this it seems unkward to me because I need to commit every change I make in one image Baseline in order to load in the other. Doing this test in the same image I am developing already caused trouble to me, lost code, some oddities, and often I had to discard the image and start over in another one. Is there a best way of testing Baselines changes? Thanks, Vitor

Re: [Pharo-users] Embedding pharo in C++
by Alexandre Bergel April 23, 2020

April 23, 2020

This is an exciting work Roland. Keep going! Bridging Pharo to other technologies is crucial, and you are doing well. Something you could do, is having Pharo running, on a different process, and exchanging (using a binary format) things between C++ and Pharo. We are doing this using CSharp and Python, and it works well. cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. > On 21-04-2020, at 09:04, Roland PlÃ¼ss via Pharo-users <pharo-users(a)lists.pharo.org> wrote: > > > From: Roland PlÃ¼ss <roland(a)rptd.ch> > Subject: Re: [Pharo-users] Embedding pharo in C++ > Date: 21 April 2020, 09:04:56 GMT-4 > To: Pharo Mailing List <pharo-users(a)lists.pharo.org> > > > The dragon has been unleashed.

AST: Adding RBComment to a node
by Mehrdad Abdi April 23, 2020

April 23, 2020

Hello, How can I make a comment on a node dynamically? - Here is a code i've tried: b:= RBParser parseMethod: 'foo self x: 2. x:=0. y:=8.'. node := b body statements at: 1. node comments: { RBComment with: 'comment' at: node stop + 1 }. b formattedCode. - The result: foo self x: 2. . x:=0. y x := 0. y := 8 - I expect: foo self x: 2. "comment" x := 0. y := 8

Hello, I like Pharo a lot but I hit a wall very often. With complex problems I do not see how to solve things in small steps. Is there somewhere who is willing to mentor me in how I can overcome that problem. Roelof

Missing Extract Method To Component refactoring
by Arturo Zambrano April 22, 2020

April 22, 2020

Hi everyone. Does anyone know what happened to the "Extract Method to Component" refactoring which is in Pharo 6, but seems to be missing in Pharo 7 and Pharo 8. I noticed there is a "Move method to another class", but it is quite different (in the sense that it does fewer checks and code editing during the refactoring). Maybe there is some project that needs to be loaded? Or it also may be the case it was not ported to Pharo7/8. In that case, maybe we can port it based on the original implementation from Pharo 6. Any information is welcome to avoid duplicated efforts. Thanks in advance. Arturo

All file accesses get externalCalledFailed exceptions.
by Michael Burns April 22, 2020

April 22, 2020

Newbie to Pharo Just installed the latest 8.0 stable image. Some things work, but anything I do to access any files gets an exception dealing with getcwd in libc.dylib. I am running MacOS Catalina. I searched and found the lib.dylib file and it is an alias to another .dylib file. Is there something else I need to install or configure? Sent from my iPad

Code Changes seems very slow in P8?
by Tim Mackinnon April 21, 2020

April 21, 2020

I havenât used P8 a lot, but I still find that the code changes tool still needs more work (I feel quite nervous about it vs. the now deprecated changes file). I noticed today on a new P8 image where I did a bit of work (not much). Having launched the image again today (and my laptop had accidentally rebooted), I opted not to load lost code (as I didnât think I had lost any) - but then I went to check what code it thought was lost and was surprised to find that on a new MacBook Pro - it takes 3-4 seconds (with no obvious wait cursor) to show 6700 events? Is this right? Obviously the UI needs improving to show some loading indicator, but why does it take such a long time to determine a smallish number of events? Or is 6700 a lot? Looking in detail it seems that the majority are due to project dependencies I loaded, but I worry that this doesnât scale very well? 100âs of thousands of events should take time, but sub 10k it seems like something odd is going on? Maybe it was always like this? Tim
