Something I'm not quite sure on, is whether using repository: 'github://....'rather than a HTTPS connection requires SSH keys to set up. Presuming so, you should first ensure you SSH is working from the command lineper... https://help.github.com/en/github/authenticating-to-github/testing-your-ssh… think a facility to do a similar user-check from within Pharo would be extremely useful.) Next, if you are on Windows, the added complexity is that "Use Custom Keys" must be enabled.(And it would be useful if that was the default for Windows. I trip over it _every_ time I start a new image.)

Hello, I feel your pain. Updated, consistent and centralized documentation is not strong in Pharo. Things are changing fast and docs don't catch up, also there is an effort to move projects to github, so usually updated stuff are there. I never use Catalog anymore because often things goes wrong. Books are only good to explain major concepts that are less likely to change over time, in order to getting started I would recommend: 1- Seaside github project: https://github.com/SeasideSt/Seaside. Their readme and wiki page seems to be very good and updated, I just evaluated this on playground and it worked as expected: Metacello new baseline:'Seaside3'; repository: 'github://SeasideSt/Seaside:v3.4.1/repository'; load I avoid using master tag as it is usually development branch or frequently has some commit that breaks everything up and and what I want is something reliable, so I always use version tags (when the projects provides one). After that, I think using the wiki ( https://github.com/SeasideSt/Seaside/wiki) or seaside web book ( http://book.seaside.st/book) can get you through all you need to know. 2- Pharo open documentation is a much better place to be getting started with Pharo: https://github.com/pharo-open-documentation/pharo-wiki 3- Then you can go and read Pharo by Example and Deep in Pharo books in order to get more information after you can get started, if you are interest, but by now you must be able to do most basic stuff with the system.. Hope that helps you getting by and fuel you interest in Smalltalk and Pharo.

Re: [Pharo-users] Refactor without formatting

by Ben Coman

That seems to violate the Principal Of Least Surprise. Whether or not it ends up getting changed, I think its worthwhile entering that directly in the issue tracker. It would assist if you could bisect to isolate which commit introduced the behaviour. cheers -ben On Wed, 20 May 2020 at 01:34, Vitor Medina Cruz <vitormcruz(a)gmail.com> wrote: > Hello, > > When I run a refactoring, Rename Method, for example, the refactoring is > reformatting the code affected.

I am new to Pharo and liked that it is a cleaned up and modern Smalltalk, but I think I'm done before I ever started.Â My biggest interest was in Seaside, yet trying to install it from instructions on the Seaside GitHub fails: Metacello new baseline:'Seaside3'; repository: 'github://SeasideSt/Seaside:master/repository'; load Trying to load packages from the catalog browser like Magritte fails. Some packages aren't updated for 8.0 and are only available for 7.0.Â Some are only available for 4.0.Â Trying to follow the book for creating a blog has ha me spend time trying to get something going to no avail. I'm not an expert programmer, but I've been in IT for 25 years and can do some C, Racket, Pascal, shell languages, awk, Perl, but I am stymied at every turn with Pharo.

Re: [Pharo-users] Pharo-Sound

by Russ Whaley

The repository browser did not list PharoSound - at least in an obvious place :) so I couldn't unload it. I created a new image - spent two hours getting Git/Iceberg working (personal problems, I guess - character flaw that this is so difficult for me). But my new image is only 70MB. My old image was 270MB. So I guess it doesn't matter how to unload PharoSound as I now have a new image... Thanks!

Pharo on Chromebook

by Jan KurÅ¡

Hi, has anyone an experience with running Pharo on Chromebook (using Crostini)? It worked reasonably well for me in the past (3 months ago), now I see rendering issues: [image: image.png] I tried with latest and greatest Pharo8 and fresh image, I see the same rendering issue. Thanks, Jan

Refactor without formatting

by Vitor Medina Cruz

Hello, When I run a refactoring, Rename Method, for example, the refactoring is reformatting the code affected. Is it possible to configure Pharo to refactor without reformatting code? Depending on the refactoring, the reformat is so intrusive that make it more worth to make the refactoring by hand. Regards, Vitor

Find/Replace class scoped

Hello, Is there a way to make find replace in a class scoped way? I can do that with finder, but I figured only with package scoping. I wanna to change the name of a variable in multiple methods, and also I would like to regex replace an expression also in multiple methods. Regards, Vitor

GPL can be good for large infrastructure projects (Linux) to reduce money driven feature fracturization of the community. cheers -ben
