CiteZen and Pharo 5 / Pharo4 tests
by Peter UhnÃ¡k Oct. 19, 2015

Oct. 19, 2015

Hi, I wanted to use CiteZen, but there's no Pharo 5 version (wouldn't even load), so I tried Pharo 4 instead but the tests are not passing: all CZBibTest fail on MessageNotUnderstood: Metaclass>>allMethodsInCategory: is this known problem? Do I need to use a very specific build of Pharo 4? Thanks, Peter

Live interaction with SQLite data from Pharo
by Offray Vladimir Luna CÃ¡rdenas Oct. 18, 2015

Oct. 18, 2015

Hi, I have followed the short tutorials[1][2] on SQLite and Pharo and my connection is working properly. But I miss some liveliness on how interact with data base, particularly after seeing the video from Doru at [3], where near to min 38 he shows a connection with a Posgresql data base which after ran on the playground results in a nice vire with a tab for putting the SQL code and another for inspecting the results in a table format, even for adding data live. Is this functionality only available on Postgres or can also be enabled on a connection for SQLite and if yes, how can it be done?

Hello, Following the recent post on SQLite, I came to read about Fossil[1]. Are any of you using Fossil for Pharo project? If so what is your required set up, script, etc.? Thanks Hilaire [1] http://www.fossil-scm.org -- Dr. Geo http://drgeo.eu http://google.com/+DrgeoEu

Pharo messaging
by Torsten Bergmann Oct. 18, 2015

Oct. 18, 2015

Hi, Lots of message apps in use today (WhatsApp, Telegram, ...) on phones and mobile devices. There is "WhatsAPI" [1] - but my understanding is that it was closed for legal/security reasons. There are other solutions like Telegram that also have an API [2]. What options do we have in Pharo these days: - to send messages from Pharo to a phone - receive messages from an app to control a Pharo image remotely from a phone or communicate Thanks T.

Pharo and SQLite
by Jimmie Houchin Oct. 18, 2015

Oct. 18, 2015

Hello, I am working on a project for my wife. I initially thought I would keep all my data inside Pharo because it is a simple project and Pharo is great at persistence in the image. But as I pursued the project it felt like I was reinventing the database. So I thought why am I considering working so hard to structure my classes and objects in such a way that I am in effect writing my own database. All of this to avoid using a "real" database. Part of my projects goals is to keep this project contained. I do not want to require my wife or whomever I share this with to have to install anything other than copy or unzip the Pharo folder. No PostgreSQL or MongoDB installs. Keep it simple. This is a goal I have for a lot of my ideas. In my 20+ years of computing and Internet. I have seen lots of applications come and go. (and no, I don't have gray hair, even though I have children older than probably half the people here.) Many years ago, my wife and I made tremendous use out of Apple Works and Microsoft Works. Apple at home and for me Microsoft at work. We loved the ease and simplicity we could throw a database together and just do stuff. It was great. In fact on my work PC I still use weekly and sometimes daily a database I wrote in 1994. I am almost at the point that Windows won't run this ancient MSWorks 4 database. I will have to move my data. Of course these tools aren't the greatest. They have significant limitations, but despite the limitations they were very empowering. My wife started to attempt something similar in LibreOffice but LibreOffice wasn't so simple. It was confusing to her. I briefly looked at LibreOffice but I am not convinced that it is the best or right tool for the job. So that sent me on an adventure to implement this in Pharo. In my learning that I don't want to reinvent the database I have initially settled on using SQLite. SQLite meets my requirements above. It is embedded in my Pharo app and only requires including the database file I create. Very portable and easy to install along with anything else in Pharo. SQLite seems like a very good match and complement to Pharo. A trusted, reliable, external persistence that is as simple and portable as is Pharo. Richard Hipp creator of SQLite has several videos describing how he believes SQLite should be used and should not be used. SQLite: The Database at the Edge of the Network with Dr. Richard Hipp https://www.youtube.com/watch?v=Jib2AmRb_rk 2014 SouthEast LinuxFest - Richard Hipp - SQLite as an Application File Format https://www.youtube.com/watch?v=8y_ABXwYtuc The videos are inspirational for using SQLite. I like what he says. I encourage watching. I have watched these and others of his including his anti-git video. I am not knowledgeable about the use of git in Pharo, but I would be interested if anybody has considered and knows the pros and cons of using Fossil instead. I know, it wouldn't get us on GitHub. I may be the only one. But that isn't a biggie for me. TL;DW (didn't watch) Use SQLite for Application File Format for persistence instead of a (zipped) pile of files and you get many benefits. Examples in videos as the wrong way, LibreOffice and git. I think using SQLite like this for Pharo would be an excellent match. We gain all the benefits of SQLite, transactions, ACID. In a tool that is nicely (non)licensed, and is used and trusted generally by most all of the software world. For Pharo this buys us an excellent, simple, equally portable persistence. It also buys us persistence that is trusted by people who don't trust the image for their data. This could possible help with people who explore Pharo but aren't comfortable about image only. Now of course it won't help the Emacs or Vim, ... people. I am exploring the idea of using Pharo and SQLite for what I would have previously used Apple/MS Works database for. At first it would be building the app/project for my wife. And during and after that project generalize some things to make a better out of the box solution for like projects. Thoughts, opinions, ideas, wisdom. Any and all appreciated. Thanks. Jimmie

SQLite error on Pharo 4.
by Offray Vladimir Luna CÃ¡rdenas Oct. 18, 2015

Oct. 18, 2015

Hi all, I have been following the instructions on [1] to install/use SQLite with Pharo 4. But when I try to run the examples I get: "Error: function unavailable". Attached is the trace of the error. I think is related somehow with the fact that I have 64 and 32 bits of sqlite3 installed in my system (Manjaro Linux) and the Native Boost is picking the 64 bits one instead of the 32 bits. I don't know how to solve this though, so any help will be appreciated. [1] http://smalltalkhub.com/#!/~PharoExtras/NBSQLite3 Cheers, Offray

Making a ring pie chart draggrable
by Offray Vladimir Luna CÃ¡rdenas Oct. 17, 2015

Oct. 17, 2015

Hi all :), When I'm starting to prototype a visualization I like to make all elements draggable so I can test easily several layouts. This works well for simple elements, but I can't understand well how to make it work with complex ones like the|||RTPieBuilder. |Consider the code at http://ws.stfx.eu/1HC0HALHUKIC . There I create a ring pie chart and visualize it. I would like to make it draggable and add more elements to a the view. I have browsed the layout chapter by Peter on Agile visualization[1], but still I don't get it. I will made a detailed reading to catch what I'm missing and redo some proposed exercises, but any help is greatly appreciated.
