[Pharo-project] InternetConfigPlugin for unix - [WAS]Tips to create a plugin with specific platform dependant stuff
by Guillermo Polito April 15, 2012

April 15, 2012

Bump :) I've been working last week a bit on the internet plugin to fetch some system proxy configuration in unix. Since - the plugin is external - it loads gconf libraries using dlopen, so the libraries are not needed during compilation nor running - if gconf library is not found, looks at the http-proxy and ftp-proxy env vars. It should break nothing :P But I'm not an expert :/. What do you think? Is it worth of integration?

Of course that can not work. .cs is source code, you of course need a compiler (if Fuel could load cs.gz, it *would be* a compiler). What you need to do is to serialize the *Objects* that are code (Classes, MethodDictioaries, CompiledMethods) using Fuel. Then the result can be loaded back using Fuel.

[Pharo-project] Some unicode initialization lost
by Guillermo Polito April 15, 2012

April 15, 2012

Unicode class>>#parseUnicodeDataFrom: is the method in charge of initialize the unicode tables telling when a char is lowercase, or digit, etc.. But it has no senders :). Maybe a first try can be something like the case mappings: Unicode class>>initializeUnicodeData UIManager default informUserDuring: [ :bar| | result | bar value: 'Downloading Unicode data'. (result := ZnEasy get: ' http://www.unicode.org/Public/UNIDATA/UnicodeData.txt') isSuccess ifFalse: [ ^ self error: 'Download failed' ]. bar value: 'Updating Case Mappings'. self parseUnicodeDataFrom: result contents readStream ]. Now, is http://www.unicode.org/Public/UNIDATA/UnicodeData.txt the correct file to load the data from? BTW, I executed that code in my image and It broke into pieces, so the existing initialization may have some problem. Dunno what happens yet. Guille

[Pharo-project] [ANN] Dr. Geo 12.04d
by Hilaire Fernandes April 15, 2012

April 15, 2012

Hello, Hopefully this release will be fine. And DrGeo comes now with the newer COG VM, so it is impressively blighting fast! Phil, you asked for a splash screen, you got it! As well the auto open of an empty sketch in Workstation edition. In fact, in the refactoring of the plate form code, I forgot to put it back. https://gforge.inria.fr/frs/download.php/30591/DrGeo.app-12.04d.zip Btw, are some of you interested to translate DrGeo in Italian, Deutsch, Swedish, Norwich,... If so contact me at hilailre(a)drgeo.eu Thanks -- Dr. Geo -- http://www.drgeo.eu
