ANN SXSoundEx for Pharo/Smalltalk

by Gareth Cox

Hi all As part of a recent project I was asked to create a small soundex thingy. http://en.wikipedia.org/wiki/Soundex I told the company that I'd do it but it'd be opensource and I'd give it to the community. They agreed so here it is! You can find it here http://www.smalltalkhub.com/#!/~riverdusty/SXSoundEx Hope it'll be useful for someone.

Re: [Pharo-users] Can Pharo meet all your computing needs?

For Emac and Pharo is common practice to build a monolithic environment where everything is reimplemented. Emacs has its own email client, git client, command shell, irc client etc etc. But then this lead me to ask the question "Why fight them when you can join them" . The problem with existing solutions , however clumsy , inconvenient and uncool they are. They are just that, solutions. I get how Alan Kay disapproves of modern iPads and many other modern technologies BUT his dynabook is vaporware. However emacs and pharo are cool and powerful they cannot compete with those specialised tools that have been in development in some cases for decades . So that led me to my second question "Why fight them , when you can join them ?" which is why it started with emacs eshell and ended up with Xterm2. However still missing all the coolness of Pharo and the language and the tools it has triggered a new question "why join when you can enslave them ?". Parasites after all are difficult to like but they happen to be one of the most powerful organisms on this planet and they are very efficient ,like viruses. So now I am exploring the concept of how Pharo can control all these apps without me having to reimplement these apps in Pharo which is just an insane amount of work to code and maintain. In my case it was not difficult to reach this conclusion since reimplementing Blender in Pharo would be an insane if not impossible amount of work for a single developer. At first I was very sceptical trying to use sockets as a way to control Blender but now I see this actually can work very well. It has its limitations but its light years easier and more efficient than the alternative. It raises some interesting questions, how Pharo can control gmail, or thunderbird, or irc client like mirc and KVIRC and XChat, or the web browser (amber could play a very important role here) or many thousands of apps out there. We certainly have the libraries to do this. On Sun, Aug 24, 2014 at 2:47 AM, Sean P.

kilon.alios wrote > I've been wondering if I can use Pharo the way I would use > Emacs, as an environment for doing everything." This is the dream - the Dynabook vision. Smalltalk was a protoype exploration of JCR Licklider's dream, articulated in the early 60s "to become interactive intellectual amplifiers for all people", or as Dan Ingalls put it "to provide computer support for the creative spirit in everyone". There is no reason why Pharo should not be able to do this. Indeed it is why its lineage exists in the first place. The only thing necessary is the effort to implement the features that matter to you. kilon.alios wrote > "* Use IRC?"

Re: [Pharo-users] Can Pharo meet all your computing needs?

"Hi folks I've been playing with Pharo recently, and really enjoying writing some programs in the Pharo environment." Hello and welcome to the Pharo family "As a result, I've been wondering if I can use Pharo the way I would use Emacs, as an environment for doing everything." No Pharo is a different beast, but beast none the less. Each one has its pros and cons. Emacs is more for CL and text editing stuff and excels at that . Pharo is more for GUI and Graphics stuff and it excels at that. Emacs is more popular and more actively developed but Pharo comes with a very powerful programming language and much more performant than elisp. Personally I use both Emacs and Pharo , I love both and I find both awesome. I use emacs for documenting stuff for Pharo , like my contribution to updating the Pharo By Example book to Pharo 3 and 4. "* Send emails to this mailing list?" I think there are libraries for dealing with emails, I dont think there is an actual email client for Pharo though if my memory serves me correctly I remember a email client for Squeak. So its definitely doable with Pharo. "* Use IRC?" Again I think there is no client for this, definitely a cool project , again doable with Pharo because it has very good support for sockets and IRC is a rather simple socket protocol. I use sockets extensively for my project "Ephestos" to make Pharo talk to Python and use Python libraries from inside Pharo even with Pharo syntax. Using sockets is actually very simple. "Start Bash?" Pharo has a command shell, similar to emacs eshell. But I dont know how powerful it is and if it has full shell support but for basic stuff it works as I have tested it personally but I prefer using Xterm 2 . If you mean call shell scripts thats doable too, also pharo can be called from the terminal and used as a bash tool , so you have many options here. " Read the Pharo documentation (e.g. Pharo By Example)?" No you cant read (AFAIK) Pharo By Example from inside Pharo but there is a help tool similar to emacs help tool. Unfortunately it has not been the preferred choice for documenting stuff. On the other hand Pillar which is a quite popular choice for Pharo documentation works on top of Latex and can export to html , markdown and pdf and of course text files. So documentation wise I think Pharo is more powerful than Emacs in what it can do. Because I happen to use Pillar a lot for updating Pharo By Example I really like it so far and I think Pharo devs have done a very good job with it. I think also because pillar syntax is very simple it should not be too hard to make pillar files viewable from inside Pharo. So I think we are close with that target too. " Is there a package manager I can use to find new tools I can use in Pharo" yes its called "configuration browser" and comes included with Pharo. If you get a latest Pharo 3 image you should already seen a lot of packages in the configuration browser, Installing them is also a single action process. "If these things do exist, how do I discover them?" the old trusted process of googling . Here some links that google returned to me http://forum.world.st/Sending-email-with-Pharo-td4647555.html https://www.youtube.com/watch?v=5m5z6p8874w http://wiki.squeak.org/squeak/1524 http://tulipemoutarde.be/2011/12/29/send-email-from-pharo-with-postmark.html

Can Pharo meet all your computing needs?

by Wilfred Hughes

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?

Re: [Pharo-users] Importing a city map in dxf/svg format to Roassal

by FranÃ§ois Stephany

Hi Offray, you can find the project on Github. https://github.com/fstephany/OSMMaps Getting started is easy: Metacello new baseline: 'OSMMaps'; repository: 'github://fstephany/OSMMaps/repository'; load. This will load Roassal2 and all its dependencies + OSMMaps. then execute OSMTile monsExample to open a draggable map centered on Mons, Belgium. Everything is more than alpha at the moment: the most basic stuff still need to be done. Check the issue on github for a todo list ;) On Thu, Aug 21, 2014 at 1:11 PM, Alexandre Bergel <alexandre.bergel(a)me.com> wrote: > Hi Offray, > > Sergio Maas has worked on google map interaction in Roassal. > With FranÃ§ois we have started an integration of OpenStreetMap. > > This is still in progress, we hope to give you some update very soon on > this. > > Cheers, > Alexandre > > On Aug 20, 2014, at 3:40 PM, Offray Vladimir Luna CÃ¡rdenas < > offray(a)riseup.net> wrote: > > > Hi, > > > > There is a project which collects maps of cities under a open licensed > (AFAIK derived from OpenStreetMap) and release them as dxf files.

Re: [Pharo-users] example custom mouse events

Hi Ben, yes, i was a bit too fast with my reply and sent it before thinking <stupid grin>, its a lowlevel thing and i mentioned it because i was thinking at that moment whether i can simplify some of my code that is using mouseEnter & mouseLeave by using some lowlevel methods. thanks for considering it anyway. werner

That prompted me to go looking for something more to learn. It seems mouseOver is generally used more low level as part of the infrastructure rather than as a user handler. Morph does not define the method 'mouseOver'. Its only defined on PanelMorph. The symbol #mouseOver is used in a few places: * PanelMorph seems the only user of the class MouseOverEventHandler which references #mouseOver in its 'mouseOver:fromMorph:' method * MultistateLabelMorph (which has no references in the Pharo Image) references #mouseOver as a Dictionary key for colours for its 'interactionState' * MorphicEvent>>isMouseOver references #mouseOver. This has three senders * DockingBarMorph>>#handleFocusEvent: checks isMouseOver to stop processing the event. * MenuMorph>>handleFocusEvent: checks isMouseOver to stop processing the event. * HandMorph>>handleEvent: checks isMOuseOver to 'sendMouseEvent' * MouseEvent>>sentTo: for type==#mouseOver sends message 'handleMouseOver:' , which is already covered in the previously provided Examples. I've added an additional example showing mouseOver usage for PanelMorph. Do you have any other usage examples for mouseOver? cheers -ben

Hi Offray, Sergio Maas has worked on google map interaction in Roassal. With FranÃ§ois we have started an integration of OpenStreetMap. This is still in progress, we hope to give you some update very soon on this.
