Re: [Sugar-devel] The stacktrace for the Pippy camera example error
Hello, @Gonzalo Odiard Ok, i'll keep on using my favorite IDE and sugar emulator @James Cameron - As Gonzalo Odiard made me notice that it is best to have my own IDE in order to build activity, I'll keep on going this way. - I'll look at my file system in pippy/libraries for the api reference - That's all I needed, for PyGame i'll look at the official api reference (and for standard modules, I'll go to the web) 2011/12/7 James Cameron qu...@laptop.org On Wed, Dec 07, 2011 at 01:26:29AM +0100, laurent bernabe wrote: I would like to develop activities in Pippy, but I am still wondering : * Does the Pippy activity allow projects made on several files ? No. See the usage section of my Pippy design document from earlier this year: http://wiki.sugarlabs.org/go/User:Quozl The usage you have asked about, allow projects made on several files, is covered by the following usage patterns: write a fresh module that imports an included example module unchanged, deriving behaviour from existing behaviour, write a fresh module that imports a modified example module, and write two fresh modules one of which imports the other, Usage patterns marked (new) are not yet implemented. I do not recommend the current version of Pippy for serious activity development. It is best used only as an introduction to single-module programming. * where is the best place to get Pippy api reference ? For the Pippy module, used by import pippy, the documentation is embedded in the Python code, read the files in library/pippy ... and if you find you don't understand something, please ask. For any other module, used by import, the documentation will depend on the module.

Yes, your last modifications made it work after about 2 or 3 seconds.
(I moved the gst initialisation and implemented the try/catch loop)
Please attach your finished camera example, then I can test it on XO,
and merge it for the next version of Pippy.
+1 please do, the next version wont have also the xolympics example.

[Sugar-devel] forcing a specific language translation
Normally, I use something like this to automatically get translations
from the right .mo file
from gettext import gettext
def _( s ):
return gettext( s )
But what if I want to force my activity to run in a different
language? (e.g. Swedish Chef Cookbook Activity)
I tried this:
import gettext
force_lang = gettext.translation('SwedishChef', languages=['sv'] )
force_lang.install( )
def _( s ):
return force_lang.gettext( s )
But it did not work and I get back the default strings from my python
code instead.
Any suggestions? Thanks!
Erik

[Sugar-devel] Sugar Digest 2011-12-07
== Sugar Digest == 1. I was on a flight from Miami to Boston with Reuben Caron last night during which we discussed the hot-button topic of Flash games. Reuben was on his way back from a deployment that was heavy into Flash and was looking for a way to wean itself from a dependency on deprecated software that was both opaque and power hungry. Having just finished porting a Flash game to Sugar--it really is not so difficult--I suggested that we encourage the deployment to Sugarize their Flash assets. So we took a quick scan through their library and chose a reflective-symmetry game as a place to start. Two hours later, we had Reflection [1] running in Sugar. Version 2, which I wrote on the train into Cambridge this morning includes collaboration and a mode of symmetry not available in the original Flash game. Ultimately, it comes down to sustainability. It is my opinion that deployments are capable of building capacity and writing simple Sugar activities that they can tailor to their needs is a skill that pays off in the short term--no need to sustain Flash--and the long term--they learn to build tools to solve problems. 2. I've been busy this week with some other programming tasks as well: enhancing Measure and Turtle Art to take advantage of stereo input: both analog audio and DC resistance modes. As a result, you can now attach multiple sensors to the microphone input of an XO 1.5 and read two channels of data. I wrote a simple Turtle Art program [2] to paint using a photo-resistor and a mechanical switch. Try doing that in Flash!! 3. Christofer is doing more Sugar hacking (See [3]). 4. Aleksey Lim has gotten multilingual chat working again on the Sugar IRC channels (Well, just bilinugual for the moment: Spanish and English). Instructions on how to use the service are found here [4]. Translation is provided by the Apertium project [5]. The project accepts contributions [6] to their translation system--those of you who are bilingual should please try to help. === Sugar Labs === Gary Martin has generated SOMs from the past few weeks of discussion on the IAEP mailing list: 2011 Nov 26th-Dec 2nd (45 emails) [7] Visit our planet [8] for more updates about Sugar and Sugar deployments. -walter -- Walter Bender Sugar Labs http://www.sugarlabs.org [1] http://wiki.sugarlabs.org/go/Activities/Reflection [2] http://wiki.sugarlabs.org/go/File:TAdual-sensor-mode.png [3] https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash4/303924_152746174826035_12719595747_169168_604539697_n.jpg [4] http://wiki.sugarlabs.org/go/Service/meeting/Usage#Multi-lingual_relaying [5] http://apertium.org [6] http://wiki.apertium.org/wiki/Contributing_to_an_existing_pair [7] http://wiki.sugarlabs.org/go/File:2011-Nov-26-Dec-2-som.jpg [8] http://planet.sugarlabs.org ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel
