Cairo
by Cameron Sanders April 24, 2012

April 24, 2012

Congrats on the release of Pharo 1.4!! Very exciting. Also, Nautilus looks nice -- in my first few minutes of using it. - One of my goals is to generate PDF reports. From Pharo, it appears that Pango/Cairo may give me a solution. And then I saw Athens, and thought it might be helpful. I used the configuration tool to load Athens, but then realized that I need to load Cairo first -- I thought maybe it would be picked up as a dependency... i am not very familiar with these configurations yet, and it appears that it did not install it. As I look around, I am having troubles finding a description of the optimal loading process for Pango & Cairo, for Pharo. My searches keep giving me very old/sub-optimal references on the forums. Nothing that works when i "do it" -- so I am obviously missing something. *Can someone please direct me to web pages describing the optimal loading technique for Pango & Cairo, or provide the Gofer lines here? Thanks in advance!* Thanks in advance! Cam

Organization for the Pharo Conf.
by StÃ©phane Ducasse April 24, 2012

April 24, 2012

Hi guys, I'm preparing the conference. I would like to make sure that we can get discussion around technology and business. I was thinking that we could have a session where you provide a presentation with 3 () slides - Your business - Your technological asset - What you can share We could put theses slides on the web as an advertisement. What I would like to get is the message that - other people should be able to see that we can do business in Pharo, - that they could get some knowledge, librariesâ¦ I'm looking for your ideas on how to setup the program so that we could have exchange on business opportunities.

See UTF8TextConverter --------------------------------- Thanks for the tip. But shouldn't that be done by the system. The database uses UTF-8. Pharo uses UTF-8 so an Ã in the database should give me an Ã in the transcript window. BTW: I tried the UTF8TextConverter and it just produces more garbage. Regards Roger

Sqlite and UTF8 Problem
by Roger Gilliar April 23, 2012

April 23, 2012

Hi, I would like to access a sqlite database from pharo. So far that seems to work. The only problem is that my sqlite database contains UTF-8 data and that for example Ã is displayed as Â¦Ã. Is there a workaround for this problem ? BTW: I'm using Pharo 1.4 and installed sqlite support like this: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfSQLite3'; load. ((Smalltalk at: #ConfigurationOfSQLite3) project version: '1.2') load: 'Tests'. Regards Roger

truly basic terminal emulation
by Daniel Lyons April 23, 2012

April 23, 2012

Hi, For fun I'm "porting" my UMIX UM implementation I wrote in C for ICFP 2006 to Pharo. For the sake of this, I need a really, really basic terminal emulator, honestly just a window showing text in a fixed-width font that I can read from and write to. Bonus if I can't move the cursor around and delete outputted text, but not necessary. CommandShell looks like overkill for what I need. I'd rather build something basic from scratch to learn more about Morphic. I'd appreciate any direction you could share with me. Thanks, â Daniel Lyons
