[Pharo-project] Proxy configuration

by Santiago Bragagnolo

Hi again. I'm using pharo in a proxyed network, and when i go to de settings section i only have the configuration of a concrete proxy, but no any one related with 'use the system configuration'. I tried to use manually #InternetConfiguration>>getHTTPProxyHost with a empty string as result (also with other messages like getRealName). I tried to execute startUp method and tried again the same methods with the same result. Im running on a pharo 1.4 latest stable release, over 'CoInterpreter VMMaker-oscog-IgorStasenko.162 uuid: e4554f9a-cc90-4826-a807-ac282b782fe4 Aug 13 2012, StackToRegisterMappingCogit VMMaker-oscog-IgorStasenko.162 uuid: e4554f9a-cc90-4826-a807-ac282b782fe4 Aug 13 2012, https://git.gitorious.org/cogvm/blessed.git Commit: aeb0705cde4b8fc57cb262dc051c5ee6dfa72a14 Date: 2012-07-26 16:38:48 +0200 By: Igor Stasenko <siguctua(a)gmail.com>' On Mac OS X (10.6.8) Then, i have two questions: 1- Is any way to configure the proxy to use the system configuration via settings browser? (in any pharo version) 2- InternetPlugin, is shipped in the default Cog compilation? Is any way to know this kind of things in Jenkins? Thanks! Santiago.

Re: [Pharo-project] #skipSeparators doesn't work for MultiByteBinaryOrTextStream

by Sven Van Caekenberghe

Mariano, What would be wrong with something more elegant, like consumeWhitespace "Strip whitespaces from the input stream." [ readStream atEnd not and: [ readStream peek isSeparator ] ] whileTrue: [ readStream next ] ? In my book #peek, which means a one-element pushback buffer, is a whole lot less of a requirement that a general #position[:] interface which actually assumes that all contents is in memory, a contradiction to the concept of streaming. Maybe these uglier versions are more efficient, but who can say for sure they are correct ? ;-) Sven On 06 Sep 2012, at 10:26, Mariano Martinez Peck <marianopeck(a)gmail.com> wrote: > Hi guys.

Don't expect too much from my implementation ;-) We can discuss latter by Skype or gtalk about the different alternatives. I would like to help in order to have a working ROS implementation at the end.

Serge, i'm diving into all this stuff right now, prototyping things to lern about the architecture and have more info about how-to-reach our goal. I'm browsing your implementation and Noury's right now, so, probably today or maybe tomorrow i'll have questions and better ideas :). Thanks to all for the answers!
