Step grane, Did you know of the PDF4smalltalk project in vw. It's quite ahead and there is also a reporting infrastructure built and guys are willing to port to other dialect Ciao Giorgio Ferraris Sent from my iPhone On Apr 24, 2012, at 7:15 AM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: > > On Apr 24, 2012, at 12:01 AM, Cameron Sanders wrote: > >> Congrats on the release of Pharo 1.4!!

[Pharo-project] [ANN] Spotlight like morph for pharo

by Guillermo Polito

Fwd :) ---------- Forwarded message ---------- From: Esteban Lorenzano <estebanlm(a)gmail.com> Date: Mon, Jan 23, 2012 at 12:53 AM Subject: [Pharo-project] [ANN] Spotlight like morph for pharo To: Pharo Development <pharo-project(a)lists.gforge.inria.fr> Hi, I want to announce a little tool I made the other day (mainly because Mariano asked for it :) Do you remember algernon, that tool who was working in pharo 1.1 and is now obsolete? I used it all the time, and I always missed the ability to open browsers without having to type the class name in a workspace, or open a browser first, then look for the class. So, I created this: Gofer it squeaksource: 'Spotlight'; package: 'ConfigurationOfSpotlight'; load. ConfigurationOfSpotlight loadBleedingEdge. if you press shift+enter, you'll get a "spotlight" like morph, with a simple text input with OCompletion inside... is very simple and I think very useful. Of course it can be enhanced in a lot of ways... but let's here the community opinion first, and see if it worths to keep adding functionality.functionality. enjoy, Esteban ps: this is also an example of why I hate morphic so much (bah... current dirty implementation): I had to extend two classes just to change the editor used by a textmorph.... come on!!!!

Re: [Pharo-users] Sqlite and UTF8 Problem

It uses multibyte Characters. UTF-8 is a storage format. If you really get UTF-8 from sqlite than the TextConverter is the right thing to do. So let's take a lowercase Ã¶. If you see something like ÃÂ¶ where the Ã¶ should be than you can be sure it is utf-8 encoded. Then you can do UTF8TextConverter new nextFromStream: 'ÃÂ¶' asString readStream to test it and get $Ã¶. If you get something different then the encoding you get from sqlite is not UTF-8. You should ask yourself who put that string into sqlite. It might be a storage failure as well. Sqlite would probably just convert everything into UTF-8 regardless what you give to it. Norbert

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

Thanks in > advance! Gofer it squeaksource: 'Athens'; package: 'ConfigurationOfAthens'; load. Then. (ConfigurationOfAthens project version: '1.0') load. (and of course you need to use Cog VM with NativeBoost and Cairo library installed on your OS). Now about your goals: yes, it should be fairly possible to generate PDFs using cairo. But more work is needed: this functionality are not exposed by Athens directly. The pango stuff is mostly done by Fernando, so i think he can tell you more. Anyways, if you don't fear to make your hands a bit dirty, we can make it, for sure. P.S. Now i felt for real, what is non-linear progress: this is when more than a single men contributing to project :) Together we are strong. I cannot even tell, where Athens would be, if not Fernando. > > Thanks in advance! > Cam -- Best regards, Igor Stasenko.

Cairo

by Cameron Sanders

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
