Adding a new reserved word
by Carla F. Griggio March 15, 2010

March 15, 2010

Hi everyone! I want to add a new reserved word to a Pharo image. I tried to find the code that gives special treatment to words like nil, true, false, self, etc. and add my new reserved word, but as though I tried to immitate some things, I was not successful. Â¿What could be the right way to do this? Â¿Can I add a reserved word just adding some code on a Pharo image? Thanks! Carla. PS: The object of doing this is nothing serious, I just want to make a friend laugh with a silly joke :)

A question about application deployment.
by Rayne March 15, 2010

March 15, 2010

http://code.google.com/p/pharo/wiki/HowToDeployAnApplication Oh that page, it talks about "shrinking" an image: "Reduce the image size by throwing out anything that is not required by your app and which is useless for your customer (unit tests, dev tools)." but it doesn't explain /how/ to do so. How does one "throw out" stuff like unit tests and dev tools? -- View this message in context: http://n4.nabble.com/A-question-about-application-deployment-tp1591431p1591… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Subclassing Float?
by Ch Lamprecht March 6, 2010

March 6, 2010

Hello, I tried to build a subclass of Float without success. More precisely, I did not find out how to build instances from it. Is subclassing Float something I should not do? I am trying to build objects, that represent Audio frequencies. They should behave like Floats but have some additional methods like 'addCent: anOffset' or 'deltaCent: aFrequency' (cent refers to a logarithmic scale used to express frequency relations). Cheers, Chris

I'm using Pharo-1.0-10508-rc2. And, yes, I was trying to "do" a comment.Â Silly me. Thanks for thinking of the obvious (to everyone but me).Â Works fine now.

Pharo screencasts - how to
by laurent laffont Feb. 11, 2010

Feb. 11, 2010

Hi, I want to share how I record screencasts for Pharocasts http://pharocasts.blogspot.com/ in case someone wants to participate. Now there's 11 screencasts. The difficult part is to have a good idea / scenario for a screencast. Comments and ideas are welcome. If you want to publish on Pharocasts I can give you write access. Or if you have a "draft" screencast I can edit it / re-record it for publishing. I try to record screencasts with a minimum duration of 5 mn. These instructions are for Linux (but I'm a beginner in video stuff). I don't know which software to use on other operating systems. Have advices ? I record with xvidcap http://xvidcap.sourceforge.net/. I define a capture zone of 800x600 (use 4:3 or 16:9 standard resolution. If not you can have poor encoding results). Set multi-frame mode (you have to right-click on the file button to access preferences, not very intuitive). I choose AVI format / MPEG 4 codec. If you open / close applications for the screencast, note that KDE has very good options to memorize / force windows positions, so they are always opened in your capture zone.(Other window managers like E17 have these sort of options). The trick is to not stop recording when you write errors, you can cut the "wrong" parts later. To edit the video, I use avidemux http://fixounet.free.fr/avidemux/. It has Qt and Gtk GUI and work on Linux / Windows / OSX / BSD ..... It's really easy to use. When you want to cut a part, you define the beginning with the A button ( Ctrl-[ ), the end with B button ( Ctrl-] ), then Edit -> Cut ( Ctrl-X ). You can navigate using arrow keys. When finished, click on save (Choose another filename !!). So now you have your screencast in .mpeg file. Note that people using MacOSX Tiger or older have problems to watch this video. So I convert in .mov using ffmpeg http://www.ffmpeg.org/ like this: ffmpeg -i my_video.mpeg -b 500k my_video.mov. (but I think it's not the best command as the video size is bigger and quality lower). To publish the video I use Vimeo http://vimeo.com/. I've tried YouTube and Daily Motion but the quality is lower or the video duration is limited. I had problems using the "standard uploader", so I switch to the "basic uploader" on the download page, works better. It's really fun to record screencasts, and a good way to show development practices. Cheers, Laurent Laffont

Hi all, I just discover Pharo, and i'm very exited by things i have seen. I have a question (google don't help me). Is it possible to create an portable executable that run a simple graphical application (gtk like), I suspect this is higly probable, but I don't find any documentation on the subject. Can you point me to some links/books on the topic? Kind regards

[ANN] seasidehosting.st for Pharo
by Adrian Lienhard Jan. 29, 2010

Jan. 29, 2010

Hi all, I'm happy to announce that seasidehosting.st now supports Pharo! There are no special settings or configurations needed. Get a Pharo/Seaside image, for instance from www.seaside.st/download/pharo, install your application, and upload it to seasidehosting.st. Before, Pharo was not supported because the special VM used did not run closure images. Since many people asked for support of Pharo, we updated the VM now. It took some time, but as promised, we managed to finish it before the upcoming Pharo 1.0 release. I'd like to thank ESUG and netstyle.ch for their continuous support of Seasidehosting! Cheers, Adrian ___________________ http://www.adrian-lienhard.ch/
