Help to get the classes/methods that were updated after compilation.
by Pernet Alexis Sept. 2, 2014

Sept. 2, 2014

Hello! So, i need to know what classes/methods have been changed so that i can run the critic browser tests on the fly. I remember there's a way to do it, but not exactly how to use it. Can i have some help with that? (or a link to somewhere that is explained) Also, i need a way to gather environments and associate them with rules, what would be the best type of collection/etc... to do that?

[ANN] Pointer Detective
by Ben Coman Sept. 2, 2014

Sept. 2, 2014

greetings all, I had an itch to scratch... I find it difficult using the tree list of the standard Pointer Explorer to track down why objects aren't garbage collected. I always fear I'm not going to notice getting caught in a reference loop. So I created a tool presenting an alternative view as a directed graph. The graph incrementally builds out from the target object as you explore it. Nodes are colourised to help manage complexity. The attached snapshot is produced from evaluating the following Workspace script... testObject := 'END5'. ref1 := { testObject. nil }. ref2 := { ref1 }. ref3 := PDTestResource new heldObject: ref2. ref1 at: 2 put: ref3. "note the reference loop this creates" PointerDetective openOn: testObject. Now I expect I'm duplicating something done before, but I couldn't find anything quickly and it was an opportunity for some goal direct learning of Morphic. Thanks to Roassal an option for a spring-force layout is provided. That code was copied rather than create a dependency, and might need to be rationalized later. The code is a bit rough from hacking around learning how to make things work, but its functional, so its time to get it out in the open. For more information please refer to the repository home page... http://smalltalkhub.com/#!/~BenComan/PointerDetective cheers -ben

Re: [Pharo-users] best solution to store data

Chris uses it on Squeak and found maintaining it on Pharo too much work. With XML you'll need to do more work than with STON, and the objects will be less readable.

Persistence on Moose browsers, showing always a selection in trees and making tree labels editable.
by Offray Vladimir Luna CÃ¡rdenas Sept. 2, 2014

Sept. 2, 2014

Hi, With the valuable help of the community and the GLMBasicExamples I have been able to build basic outlining interface and functionality. Here is a screenshot: http://www.enlightenment.org/ss/e-53f4243a4dc127.49773492.jpg There are some issues: 1. Now I would like to make the nodes in the tree persistent in the sense that if I wrote something in the node body (left upper part of the browser) and I select another node, when I visit the previous node, the text in the body still is there. How can I do this? 2. I would like to make the current node always selected by this blue highlighting. With some operations like moving nodes to the left or to the right, the current node gets out of focus, despite of the operations being done over it. There is any way to say Moose browsers where to put the selections, besides of explicit selection with the mouse. 3. Some time ago I asked about how to make tree labels (headers), at the left of the browsers editable. There is any way to make this? Thanks a lot, Offray

GUI construction under Pharo
by Ichiseki Sept. 2, 2014

Sept. 2, 2014

Hi For what I've read and study Smalltalk was great a RAD, it was infact used a lot in financial services for that reason. Now I see that most commercial versions of Smalltalk have a GUI builder, but non of the open source. Wouldn't have a GUI building tool be a priority? Perhaps this is already done? best Ichiro -- View this message in context: http://forum.world.st/GUI-construction-under-Pharo-tp4775654.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] [Article] Reddit.st - In 10 Cool Pharo Classes

Sven, This is really an excellent piece. You must have put a lot of thought into making it that short and concise. It's hard to belÃeve someone can cover glorp, seaside and even a domain in such a short article! There is very little in the code that's Pharo specific. The only component that will need significant changes is the captcha. String formattÃng and #asWords come to my mind. For a Smalltalker, this shouldnt be too hard.

[ANN] HelloPharo - webapp deployment tool
by FranÃ§ois Stephany Sept. 1, 2014

Sept. 1, 2014

Hello, At Ta MÃ¨re, we are used to deploy Ruby/Rails application with Heroku or on VPS with Capistrano. Almost everybody uses the same tools and techniques in the Rails community so deployment is quite easy once you grasp the process. The same process was quite frustrating with Pharo. To solve that, we've built HelloPharo. It is a tool to deploy small apps to a Linux VPS/VM. It is heavily inspired by Capistrano, it prones convention over configuration and it wants to be full stack (e.g., serve the assets, restart the processes). It is built with Ansible. We haven't released a fixed version yet but the tool starts to be in a good-enough shape to be shown. We want to grab some feedback and fix the most obvious limitations (see the README for more) before releasing version 0.1.0. If you or your company uses a well defined process to deploy pharo webapps, we are all ears. We think that having a canonical way to deploy simple apps is a must if we want to see wider Pharo adoption for small web companies. This process *must* be Unix friendly if we want to attract Python or Ruby people. Most of them are Devops anyway, the command line is their friend, NOT something they want to avoid. Pull requests (for code or instructions in the README) are more than welcome. The code and the documentation are MIT licensed. https://github.com/fstephany/hello-pharo/ Cheers, Francois
