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

Re: [Pharo-users] [squeak-dev] ESUG Squeak DCI image posted

(Copy of post on Squeak list) Hi Hannes, There were no PowerPoint slides. A last minute change to the talk was to move the slides to persistent workspaces in the demo image. This change was not captured in the image I posted before going to Cambridge. The post is now updated: fulloo.info/Downloads/BabyIDE-3a.zip The first slide is the top of the PersistentWorkspace named 'Introduction'. The second slide is at the bottom of that workspace. The demo program is in the colored window. There are 3 yellowbutton commands (use cases) 'animate shapes' - objects come and go 'animate roles' - animates the message flows of the repeated execution of some use case. All flows have the same topology. ALT-1 traces object ids. ALT-2 adds class names . ALT-3 adds role names. 'animate chaos arrows' animates message flows with no common topology. DCI has nothing to offer for such executions. TheWorldMenu>>open...>>BB5BankTransfer runs a very simple demo of the DCI concepts. (Transfer money from one bank account to another.) TheWorldMenu>>open...>>BabyIDE1>>BB5Bank opens a DCI browser on the same example. (Recommended as a first study.) enjoy --Trygve On 29.08.2014 06:32, H.

Installing STON from a playground/workspace
by Offray Vladimir Luna CÃ¡rdenas Aug. 28, 2014

Aug. 28, 2014

Hi, Last night I was playing with STON for a while. There is still things to learn (and I have already made my questions in the proper thread) but so far I have really like it. I installed it from Configuration Browser, but I would like to install it from a playground/workspace. I know where is located at SmalltalkHub and I can see there the Monticello registration, but in the chapter about Monticello this seems to be used for source control with graphical tools. How can I install STON from a playground/workspace instead of using graphical tools like Monticello or Configuration Browser? How can I know this from the SmalltalkHub page? Thanks Offray

Unintuitive behavior of class-side initialize
by webwarrior Aug. 28, 2014

Aug. 28, 2014

As class is just an object in Smalltalk, it would be reasonable to believe that #initialize message is always sent to class on creation. However, that's not true. It is only sent to classes that redefine #initialize. Also sending super initialize may lead to problems. None of these is mentioned in documentation (I assume Pahro By Example is the official one). It only says that #initialize is sent when class is loaded into memory. I think either this behavior should be made more consistent, or excplicitly mentioned in the docs. -- View this message in context: http://forum.world.st/Unintuitive-behavior-of-class-side-initialize-tp47750… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

[ANN] Teapot 0.8 micro web framework
by Attila Magyar Aug. 28, 2014

Aug. 28, 2014

Hello, I'd like to announce a new micro web framework called Teapot. It follows a similar philosophy than other lightweight frameworks like Sinatra/Bottle/Flask/Spark. Teapot is built on top of the Zn HTTP components, and less than 500 lines long.

Can Pharo meet all your computing needs?
by Wilfred Hughes Aug. 27, 2014

Aug. 27, 2014

Hi folks I've been playing with Pharo recently, and really enjoying writing some programs in the Pharo environment. As a result, I've been wondering if I can use Pharo the way I would use Emacs, as an environment for doing everything. For example, can I use Pharo to: * Send emails to this mailing list? * Use IRC? * Start Bash? * Read the Pharo documentation (e.g. Pharo By Example)? If these things do exist, how do I discover them? Is there a package manager I can use to find new tools I can use in Pharo?

DCI
by Trygve Reenskaug Aug. 26, 2014

Aug. 26, 2014

Hi Dan, You made me very happy when you made it to my talk on Thursday. It was impossible for me to present a new paradigm in less than 30 minutes, but I hope I triggered your curiosity. I think your best next step would be to read my article on the DCI Execution model http://fulloo.info/Documents/DCIExecutionModel-2.1.pdf (I hope you will put me right where I have misunderstood something.) The simplest possible example that illustrates the DCI concepts is /BB5BankTransfer/. You can run it and browse its code in my current DCI Squeak image http://fulloo.info/Downloads/BabyIDE-3.zip It would be great if we could do serious work on a realization of the Dynabook dream together. Pharo may be a good starting point because its community seems very open to new ideas. Cheers --Trygve PS. The BabyIDE is an application browser rather than a class browser. There is a kind of user manual embedded in this old article http://fulloo.info/Documents/200904commonsense.pdf PPS. I stick to a very old image because I cannot as yet file out DCI Contexts and role methods. Bootstrap to a better image is therefore impracticable.
