[opensuse-ruby] Sharing rails plugins
by Josef Reidinger 30 Nov '09

30 Nov '09

Hi, nowadays, we share gems between our application. Is possible to share rails plugins? I know at least about one ( maybe two if we use smartly rest-auth) which is packed in vendor/plugins/ of two projects. Is there any way how we could package plugin and use it from all project (so we could fix problem in one place?) thanks Josef -- Josef Reidinger YaST team maintainer of perl-Bootloader, YaST2-Repair, webyast (language,time,basesystem,ntp) -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-ruby+help(a)opensuse.org

Hi, in Linux Journal 12/2009 (p12) Reuven M. Lerner writes summaries about Ruby, Rails, JS and Git. The interesting twist is that Pragmatic Programmers have a special discount of 40% on everything until Nov 25: http://media.pragprog.com/newsletters/2009-11-18.html The titles mentioned by Lerner are: http://www.pragprog.com/titles/ppmetr/metaprogramming-ruby "showing you how to use metaprogramming techniques and suggesting when they might be appropriate or useful" http://www.pragprog.com/titles/tsgit/pragmatic-version-control-using-git "good introduction to Git and covers the basics nicely" -- Martin Vidner, YaST developer http://en.opensuse.org/User:Mvidner Kuracke oddeleni v restauraci je jako fekalni oddeleni v bazenu

[opensuse-ruby] gem2rpm and dependencies
by Marcus Rueckert 14 Nov '09

14 Nov '09

hi, i just committed a small fix to gem2rpm in d:l:r:extensions. in the past our templated also added development dependencies to the (Build)Requires list of the spec. those are usually not needed at runtime. when you update a package next time run gem2rpm-opensuse on the new gem file again and diff the output with the existing spec file. just updated nokogiri that way. darix -- openSUSE - SUSE Linux is my linux openSUSE is good for you www.opensuse.org -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-ruby+help(a)opensuse.org

[opensuse-ruby] WebYaST: loading patches and status in the control center
by Ladislav Slezak 09 Nov '09

09 Nov '09

Hi all, I'd like to discuss the problem reported in bug #550934 ('It takes minutes to refresh "system is up to date" and "system is healthy"') It takes very long time to load the initial patches and system status information which is displayed on the first page (the WebYaST control center) using AJAX requests. I already have implemented caching in the patches module so the available patches are not evaluated in every control center reload. But the first call still takes much time... The problem is that the first patch status request triggers repository metadata download and cache rebuild which in case of slow/bad/overloaded network connection can take several minutes (as reported in the bug). A similar problem is in the status module, but not that serious - the status is read from the local machine so network is not involved in this case. And even on a slow machine it won't block for more than several seconds. I have these possible solutions for reading the patch status: * don't display the status messages at all (IMO bad solution, I find the overview messages quite useful...) * make displaying of the status messages configurable (so users can hide and disable status loading if it's too slow) * use a background job for reading patches (display a generic message like "Reading patches" when the request takes too long and refresh the status after some time again to get the real status.) AFAIK an AJAX request cannot be stopped (at least the [Stop] button in FF is disabled when the page is loaded but an AJAX request is in progress). I'd prefer the last solution. Any other suggestion/solution? Thank you in advance!

[opensuse-ruby] How to package application which aggregate css
by Josef Reidinger 06 Nov '09

06 Nov '09

Hi, I want use in webyast aggregation of css in template (see stylesheet_link_tag option :cache). But I found problem that rails create new aggregated template in stylesheets directory and this directory doesn't have permissions for yast as webyast cannot modify itself sources, css or javascript due to security reason. Do you have similar problem and how you solve it? If I try to solve it by symlink, but to writable directory by webyast, but it uses touched file. Is correct solution if we generate cache css during building via cat? thanks, Josef -- Josef Reidinger YaST team maintainer of perl-Bootloader, YaST2-Repair, webyast (language,time,basesystem,ntp) -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-ruby+help(a)opensuse.org

[opensuse-ruby] New video reviews
by Josef Reidinger 03 Nov '09

03 Nov '09

Hi, in short: I update wiki page with two new videos - http://en.opensuse.org/YaST/Web/Development/TrainingKit/Learning_Ruby_and_R… longer description: First what I see is instruction video from railscast about new things in rails 2.3 (so little older). It introduce three features. Scope and batches is useful for ActiveRecord (database). Third one is method try on Object. I think it is really useful method which we should start using to simplify our code (but do not overuse). especially if code contains if o && o.map && o.map[:test] you can simple type if o.try(:map).try(:"[]",:test) If you don't know this feature I suggest look at that short video, because your quality of your code is limited by your knowledge of used api. Second one is from Gotham conference SOLID object design. I really recommend this video, because if you are not design guru which knows the latest news you give a lot of new ideas how to improve your code quality (so everyone in webyast team should look at it, especially if he want change something in framework). The presentation shows in example what is advantage of dynamic languages and why rails has so popular api. It shows how you can write code which need not to modify much and which is easily extendable. Also shows what to do if your class depends on class (libraries, modules, config files) which is changed more often then your class. It takes 47 minutes, but it is full of information ( I don't fall asleep which detect really good presentation and speaker :) -- Josef Reidinger YaST team maintainer of perl-Bootloader, YaST2-Repair, webyast modules language and time -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-ruby+help(a)opensuse.org
