[opensuse-ruby] Refactoring: Ruby Edition
by Klaus Kaempf 21 Oct '09

21 Oct '09

This book looks very promising, esp. with the co-authors Martin Fowler and Kent Beck. Having read Martin Fowlers "Refactoring" book, I can almost blindly recommend this Ruby Edition: http://www.pearsonhighered.com/educator/product/Refactoring-Ruby-Edition/97… Klaus --- SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg) -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-ruby+help(a)opensuse.org

[opensuse-ruby] Rails Anti-patterns
by Ladislav Slezak 20 Oct '09

20 Oct '09

Hi, I watched quite intersting Rails video last week (http://goruco2009.confreaks.com/30-may-2009-14-45-into-the-heart-of-darknes…) here are the most interesting suggestions I remember: 1) Know APIs - it is very important to know the standard Ruby library and Rails enhancements to avoid reinventing wheel in your code and write the code efficiently. See http://ruby-doc.org/core http://ruby-doc.org/stdlib http://api.rubyonrails.org 2) Learn common Ruby constructs like value ||= 1234 (instead of: value = 1234 if value.nil?) if value ... (instead of: if not value.nil?) 3) Define a common coding style and document it, ensure that new team members read it and are familiar with it. Document every decision you make. 4) Use tools like 'reek' to check the quality of the code 5) Write useful tests (do not test components outside your application) 6) Use a build server (like Integrity or Hudson) The video contains more tips, it's worth of seeing. -- Best Regards Ladislav Slezák Yast Developer ------------------------------------------------------------------------ SUSE LINUX, s.r.o. e-mail: lslezak(a)suse.cz Lihovarská 1060/12 tel: +420 284 028 960 190 00 Prague 9 fax: +420 284 028 951 Czech Republic http://www.suse.cz/ -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-ruby+help(a)opensuse.org

[opensuse-ruby] *args
by Duncan Mac-Vicar Prett 19 Oct '09

19 Oct '09

I just got the question of what does something like this means: some_method(*foo) This is the splat or expand operator (not a real operator), so if foo is an array, every element becomes an argument So some_method(*[1,2,3]) is equivalent to some_method(1,2,3) Or you can for example create an array from an element and another array: [1, *[2,3,4]] is equivalent to [1,2,3,4] def some_method(arg1, *args) end is used in parameters to implement variable number of arguments. Ruby matches normal parameters, then parameters with defaults and the rest goes to the array argument. If you call some_method(1,2,3,4) -> arg1=1 args=[2,3,4] You can read about this in Ruby Programming Language, section 6.4.3 http://books.google.de/books?id=jcUbTcr5XWwC&pg=PA187&lpg=PA187&dq=ruby+arr… Duncan -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-ruby+help(a)opensuse.org

[opensuse-ruby] %gem_cleanup
by Duncan Mac-Vicar Prett 19 Oct '09

19 Oct '09

Some gems put the ext/ source directory inside the gem, causing 2 types of warning/errors: - the source .c files get inside the gem, causing rpmlint to complain - sometimes the library gets duplicated in ext and lib /usr/lib64/ruby/gems/1.8/gems/nokogiri-1.3.3/lib/nokogiri/nokogiri.so /usr/lib64/ruby/gems/1.8/gems/nokogiri-1.3.3/ext/nokogiri/nokogiri.so because it is build in one and installed in the other. The ext/ one is useless and ignored, but makes the buildid extractor dizzy when creating debuginfo packages. As all rpm gems contain: %gem_install %{S:0} %gem_cleanup Shouldn't %gem_cleanup do rm -rf %{buildroot}/%{_libdir}/ruby/gems/%{rb_ver}/gems/%{mod_name}-%{version}/ext ? (I am doing this in a couple of gems already) -- Duncan Mac-Vicar P. - Engineering Manager, YaST SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg) -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-ruby+help(a)opensuse.org

[opensuse-ruby] Rails videos - a wiki page?
by Ladislav Slezak 16 Oct '09

16 Oct '09

Hi, I just have sent a report about Rails videos via email. What about a summary wiki page? With short description and rating for each video or blog article? I mean sending an email is OK, but it's lost in time, if you have spare time and you would like to watch a video or read a blog it would be nice just to look at a wiki page and select one which is rated well and is relevant to you or looks interesting to you. What do you think about it? -- Best Regards Ladislav Slezák Yast Developer ------------------------------------------------------------------------ SUSE LINUX, s.r.o. e-mail: lslezak(a)suse.cz Lihovarská 1060/12 tel: +420 284 028 960 190 00 Prague 9 fax: +420 284 028 951 Czech Republic http://www.suse.cz/ -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-ruby+help(a)opensuse.org

[opensuse-ruby] Rails video: Into the Heart of Darkness: Rails Anti-Patterns
by Ladislav Slezak 16 Oct '09

16 Oct '09

I just have watched "Into the Heart of Darkness: Rails Anti-Patterns" Rails video: Anti-patterns are wrong solutions which people do again and again when solving a common problem. This video describes how to avoid anti-patterns in Rails - study standard libraries in Ruby and Rails, do code review in team, discuss/set common rules and document them, use metrics to check the code (reek or metric_fu), use a build server, don't write useless tests... A must-see video, describes how to avoid common problems in Rails. -- Best Regards Ladislav Slezák Yast Developer ------------------------------------------------------------------------ SUSE LINUX, s.r.o. e-mail: lslezak(a)suse.cz Lihovarská 1060/12 tel: +420 284 028 960 190 00 Prague 9 fax: +420 284 028 951 Czech Republic http://www.suse.cz/ -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-ruby+help(a)opensuse.org

[opensuse-ruby] Rails videos: "Building Blocks of Modularity" and "Improving the Usability of Your RoR Applications"
by Ladislav Slezak 15 Oct '09

15 Oct '09

Hi all, I have spent my learning time watching two rails videos: Building Blocks of Modularity (lenght: ~30 minutes) ----------------------------- http://mwrc2009.confreaks.com/14-mar-2009-18-10-the-building-blocks-of-modu… This video describes kinds of bindings between parts of an application and how to make the bindings weak so changes in one module affect the other modules as least as possible. My rating: Nice video, worth of seeing. Usually known facts, but grouped together in an interesting context. Improving the Usability of Your RoR Applications (lenght: ~30 minutes) ------------------------------------------------ http://mwrc2009.confreaks.com/14-mar-2009-12-30-improving-the-usability-of-… I found the first half the most interesting, there are several tips how to make UI good looking and how to ensure that user feels safe and comfortable using your application. One of the examples is gmail's status message after deleting an email - it displays "undo" link in the successful message so the user can easily revert the action after a mistake. The second part displays changes in a specific application, this part was not much interesting for me. My rating: I would suggest it even for non-UI designers, at least the first part. -- Best Regards Ladislav Slezák Yast Developer ------------------------------------------------------------------------ SUSE LINUX, s.r.o. e-mail: lslezak(a)suse.cz Lihovarská 1060/12 tel: +420 284 028 960 190 00 Prague 9 fax: +420 284 028 951 Czech Republic http://www.suse.cz/ -- To unsubscribe, e-mail: opensuse-ruby+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse-ruby+help(a)opensuse.org
