The three rules of Ruby Q.: 1. Please do not post any solutions or spoiler discussion for this quiz until 48 hours have passed from the time on this message. 2. Support Ruby Q. by submitting ideas as often as you can: [http://www.rubyquiz.com/](http://www.rubyquiz.com/) 1. Enjoy! Suggestion: A [QUIZ] in the subject of emails about the problem helps everyone on Ruby T. follow the discussion. Please reply to the original quiz message, if you can. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= by Sean C. The goal of cat2rafb is to implement a command line utility that will allow you to submit arbitrary text to [http://rafb.net/paste/](http://rafb.net/paste/) and get the URL for the text back. Bonus points for pushing the URL through [http://rubyurl.com/](http://rubyurl.com/) to make it more manageable. cat2rafb could work like cat, taking files as input or text until ^D after entering the command. ---

And we should submit our solutions to rafb (after the spoiler period), as well as to the list? Nice self-referential touch! Regards, Paul. ---

My solution is attached (It’s also at [http://rubyurl.com/mgX](http://rubyurl.com/mgX) but I know these messages are archived so I included it here). It’s a pretty short thing and not the cleanest code but this was one of those ‘just get it written’ things for me 🙂 Synopsis: cat2rafb.rb [-nNickname] [-dDesc] [-lLanguage] [-cConvtabs] [-r] [[-tText] | [FILES, …]] Options: -n - Specify nickname to paste with (default: ENV[‘USER’] || ‘unknown’) -d - Description of paste (default: none) -l - Language for syntax highlighting (default: Ruby unless -R option is passed: then Plain Text) -c - Convert tabs to specified number of spaces (default: No) -r - Display only rubyurl for this paste (default: both rafb & rubyurl) -R - Rafb only - don’t get a rubyurl for this paste -t - Specify text on commandline, rather than reading files. If no -t or filenames are supplied, STDIN is read. -t precludes reading of any file. To get a list of valid language and tab-conversion lengths, you can just pass the appropriate option with no value, e.g. ``` ./cat2rafb.rb -l ./cat2rafb.rb -c ``` Examples: ./cat2rafb.rb somefile.txt ./cat2rafb.rb -nMyNick -lC++ -R myfile.c ./cat2rafb.rb -n’Long Nick’ -d’Ruby code’ -t’print if ~/^\d+:/’ -r ./cat2rafb.rb -c2 -lruby -nmetoo -d’From stdin’ Thanks for another interesting quiz, a rafb paster seems like a good thing to have 🙂 ---

Most of the code sets up the command-line interface so that the user can specify options such as a nickname, a description, tab expansion, and the language used for (a rather discreet) syntax highlihting. A summary of the command-line syntax can be obtained by typing cat2rafb --help on the command line or by require ‘cat2rafb’ cli = Cli.new; puts cli.parser.help in ruby. =end ---

You really thought outside the box, eh? Anyhow, personally I like the look of the site (my standard VIM setup is a black background with white text.) Also the syntax highlighting is nice looking.

I decided I didn’t like rafb’s Ruby highlighting, so I set up an alternate server that uses the “syntax” gem to handle it. It uses the simply\_restful plugin to expose a REST API for creating pastes. Here’s a quiz submission that posts to rpaste, instead of [rafb.net](http://rafb.net): [http://rpaste.com/paste/7](http://rpaste.com/paste/7) Feature requests and better CSS submissions welcome. 🙂 –Wilson. ---

It isn’t pretty and it isn’t feature rich, but it does get the job done.
