Best of Ruby Quiz (Pragmatic Programmers). Volume 1
by James Edward Gray
Code Cleaning⏎ ⏎ I'm always very vocal about how Ruby Quiz isn't interested in golf and obfuscation. It's my own private fight for clean code.⏎ To be fair, though, you can really learn a lot from practices such as golf and obfuscation. It will teach you a surprising number of details about the inner workings of your language of choice.⏎ Here's my compromise.⏎ This challenge is to utterly clean some famous examples of compressed Ruby code. Refactor the code until it's as readable as possible, whatever that means to you.⏎ For those who faint at the sight of dense code, I offer an "easier" challenge. Try this code by Mauricio Fernandez:⏎ code_cleaning/wiki.cgi⏎ #!/usr/bin/ruby -rcgi⏎ H,B=%w' HomePage w7.cgi?n=%s' ;c=CGI.new' html4' ;n,d=c[' n' ]!=' ' ?c[' n' ]:H,c[' d' ];t=`cat #{n}`;d!=' ' &&`echo #{t=CGI.escapeHTML(d)} >#{n}`;c.instance_eval{out{h1{n}+a(B%H){H}+pre{t.gsub(/([A-Z]\w+){2}/){a(B%$&){$&}}}+form("get"){textarea(' d' ){t}+hidden(' n' ,n)+submit}}}⏎ If you prefer a "trickier" challenge, I offer this famous code from Florian Gross. Just take a deep breath before turning the page....🏁
