Moose browsers: Updating an object value from a text pane and from an emergent window
by Offray Vladimir Luna CÃ¡rdenas Sept. 13, 2014

Sept. 13, 2014

Hi, I'm trying to restate my question to see if I have more luck with any answer this time. I'm making advances with an outliner like app for writing and now I can add nodes move them and store them in the really nice STON format. But because information on trees is not editable, I would like to try another approach: To create an emergent window and put the node tree and node tags on it, and the update the this values on the tree node. Also, I would like to update some objects from the a Glamour text pane, without any special button or action, just while I'm writing on them. If this is not possible which is the message to select all text in a body panel and to send it to a object? I will be doing some further advances by my own and keep you posted (may be with some more specific/better questions on how to get this behaviour from Moose browsers). Cheers, Offray

Fileouts line ending (^M and noeol in Vim)
by Esteban A. Maringolo Sept. 12, 2014

Sept. 12, 2014

Is there a way to change the default line ending of fileouts from mac to unix? Or alternatively... how to deal with current line endings in Vim? I'm using ":e ++ff=mac", then ":set ff=unix" and then saving it again. But there may be a better way. Thank you! Esteban A. Maringolo

The fourth R
by Trygve Reenskaug Sept. 12, 2014

Sept. 12, 2014

I have for some time been pondering two problems. One is to identify the fourth R in *R*eading, w*R*iting, a*R*ithmetic, and p*R*ogramming. There are many contenders for the kids' first step. I believe the English government has chosen Phyton as a first language. Scratch has a certain popularity, there are many others. My concern is "what comes next"? I want the kid to gradually build a mental model of what computing is all about. Learn a little, do a little, lean more, do more, etc. up do old age. This goes much deeper than any programming language. It's a bit as learning to read. Personally, I "broke the reading code"at an early age. Since then, I have been learning more and more. What I read today would have been incomprehensible to me 75 years ago. But my basic mental model of what reading is all about has remained unchanged. I have never had to unlearn anything. I suggest that true object orientation (not class orientation) can form the foundation for the human mental model of computing. Internalize it and live with it forever. ------------------------------------- The other problem is to find a better example for DCI presentations. It should 1. Be executable and have a cool demo effect. 2. Its domain model should be obvious from the demo. 3. It should have very few and very simple Data classes. 4. It should have a Context that is clearly and obviously separate from the Data. 5. It should scale to any number of Contexts (use cases) without changing the Data classes. ----------------------------------------- /Last night I got an idea for an example: A waltzing couple. (See the attached for a picture and Wikipedia for a movie of the use case)./ The program needs one simple class for a moveable shape and a DCI Context for each dance (waltz, foxtrot, tango, ... for two role, polonaise for more.) The example will clearly demonstrate the wisdom in separating what the system IS from what the system DOES since the simple Shape class would be overloaded with instance methods for all dances. What do you think? --Trygve -- Trygve Reenskaug mailto: trygver(a)ifi.uio.no Morgedalsvn. 5A http://folk.uio.no/trygver/ N-0378 Oslo http://fullOO.info Norway Tel: (+47) 22 49 57 27

Re: [Pharo-users] Is anyone interested in developing a package for Google's Data API?
by Andy Burnett Sept. 12, 2014

Sept. 12, 2014

á§ Sven said <<< Hi Andy, I think we have all the building blocks to do this (ZnClient from Zinc, HTTPS from Zodiac, OAuth2 from Zinc-SSO, JSON from NeoJSON), so that is good. But there are a large number of Google APIs ( https://developers.google.com/gdata/docs/directory) each of them containing lots of functionality. There are deprecation warnings on some of them. It is of course necessary to first fully familiarise oneself with each of them and the application they connect to. When some basic calls work, the next step would indeed be to make nice object models for each of them. Some people on this list have built these kinds of API before (like Sean's Flicker Client). I also think that once one of them is done, others could be implemented by many different people, like students. >>> Yup, I totally agree. We have most of the pieces, and we just need a project to assemble them. My suggestion is that we focus on the Spreadsheet services first. This seems to be the most flexible/useful one. Once that is working, we could develop the other packages. So, would anyone like to take up this project? Cheers Andy

Is anyone interested in developing a package for Google's Data API?
by Andy Burnett Sept. 11, 2014

Sept. 11, 2014

I use Google's spreadsheet and word processor a lot. I would love to be able to access the data through Pharo. I can envisage all sorts of use-cases such as manipulating data collected through the spreadsheet forms, through to generating slide shows by writing to their presentation app. The thing that has held me back is the lack of a package which presents e.g. Spreadsheet as an object with a collection of methods. There are libraries for Java/Python/etc., but nothing - that I am aware of - for Pharo. Would anyone be interested in developing one? I could certainly contribute some funds towards the effort, and others may be able to do likewise. Cheers Andy á§

Strange colour reversal on the Spec site
by Andy Burnett Sept. 11, 2014

Sept. 11, 2014

Hello, I am posting here, because I couldn't find a Spec specific list. Two things: 1. The colour scheme for all the code examples on the site seems to have gone very odd. The text is now a light blue/green on a white background. Almost completely illegible. Has someone changed a css file? 2. I noticed in the news section that the license has changed to GPL, because of a disagreement with the direction of Pharo. Could someone explain what the disagreement was, and whether this is something we should be concerned about? Cheers Andy á§

Workshop on Visual Data Narratives using Roassal/Pharo in our local hackerspace in BogotÃ¡ Colombia
by Offray Vladimir Luna CÃ¡rdenas Sept. 10, 2014

Sept. 10, 2014

Hi, This is just a short mail to let you know whats happening here on the Pharo/Roassal front. We will be starting our workshops on what we I call Visual Data Narratives. Details (in Spanish) here: http://hackbo.co/hackboweb/eventos/evento/338 Cheers, Offray ps: I will show the Moose outliner, in its alpha stage. Hopefully the threads where I ask how to solve the problems will move a little more and we will be able to integrate this to the workshops memories building.
