Descriptive configuration files for Ruby written in Ruby. Loquacious provides a very open configuration system written in ruby and descriptions for each configuration attribute. The attributes and descriptions can be iterated over allowing for helpful information about those attributes to be displayed to the user. In the simple case we have a file something like Loquacious.configuration_for('app') { name 'value', :desc => "Defines the name" foo 'bar', :desc => "FooBar" id 42, :desc => "Ara T. Howard" } Which can be loaded via the standard Ruby loading mechanisms Kernel.load 'config/app.rb' The attributes and their descriptions can be printed by using a Help object help = Loquacious.help_for('app') help.show :values => true # show the values for the attributes, too Descriptions are optional, and configurations can be nested arbitrarily deep. Loquacious.configuration_for('nested') { desc "The outermost level" a { desc "One more level in" b { desc "Finally, a real value" c 'value' } } } config = Loquacious.configuration_for('nested') p config.a.b.c #=> "value" And as you can see, descriptions can either be given inline after the value or they can appear above the attribute and value on their own line.

== ICU4R - ICU Unicode bindings for Ruby ICU4R is an attempt to provide better Unicode support for Ruby, where it lacks for a long time. Current code is mostly rewritten string.c from Ruby 1.8.3. ICU4R is Ruby C-extension binding for ICU library[1] and provides following classes and functionality: * UString: - String-like class with internal UTF16 storage; - UCA rules for UString comparisons (<=>, casecmp); - encoding(codepage) conversion; \ - Unicode normalization; - transliteration, also rule-based; Bunch of locale-sensitive functions: - upcase/downcase; - string collation; \ - string search; - iterators over text line/word/char/sentence breaks; \ - message formatting (number/currency/string/time); - date and number parsing. * URegexp - unicode regular expressions. * UResourceBundle - access to resource bundles, including ICU locale data. * UCalendar - date manipulation and timezone info. * UConverter - codepage conversions API * UCollator - locale-sensitive string comparison == Install and usage > ruby extconf.rb > make && make check > make install Now, in your scripts just require 'icu4r'. To create RDoc, run > sh tools/doc.sh == Requirements To build and use ICU4R you will need GCC and ICU v3.4 libraries[2]. == Differences from Ruby String and Regexp classes === UString vs String 1. UString substring/index methods use UTF16 codeunit indexes, not code points. 2. UString supports most methods from String class. Missing methods are: capitalize, capitalize!, swapcase, swapcase! %, center, ljust, rjust chomp, chomp!, chop, chop! \ count, delete, delete!, squeeze, squeeze!, tr, tr!, tr_s, tr_s! crypt, intern, sum, unpack dump, each_byte, each_line hex, oct, to_i, to_sym reverse, reverse! succ, succ!, next, next!, upto 3. Instead of String#% method, UString#format is provided. See FORMATTING for short reference. 4. UStrings can be created via String.to_u(encoding='utf8') or global u(str,[encoding='utf8']) calls. Note that +encoding+ parameter must be value of String class. 5. There's difference between character grapheme, codepoint and codeunit. See UNICODE reports for gory details, but in short: locale dependent notion of character can be presented using more than one codepoint - base letter and combining (accents) (also possible more than one!), and each codepoint can require more than one codeunit to store (for UTF8 codeunit size is 8bit, though \ some codepoints require up to 4bytes). So, UString has normalization and locale dependent break iterators. 6. Currently UString doesn't include Enumerable module. 7. UString index/[] methods which accept URegexp, throw exception if Regexp passed. 8. UString#<=>, UString#casecmp use UCA rules. === URegexp UString uses ICU regexp library. Pattern syntax is described in [./docs/UNICODE_REGEXPS] and ICU docs. There are some differences between processing in Ruby Regexp and URegexp: 1. When UString#sub, UString#gsub are called with block, special vars ($~, $&, $1, ...) aren't set, as their values are processed through deep ruby core code. Instead, block receives UMatch object, which is essentially immutable array of matching groups: "test".u.gsub(ure("(e)(.)")) do |match| \ puts match[0] # => 'es' <--> $& puts match[1] # => 'e' \ <--> $1 puts match[2] # => 's' <--> $2 end 2. In URegexp search pattern backreferences are in form \n (\1, \2, ...), in replacement string - in form $1, $2, ... NOTE: URegexp considers char to be a digit NOT ONLY ASCII (0x0030-0x0039), but any Unicode char, which has property Decimal digit number (Nd), e.g.: a = [?$, 0x1D7D9].pack("U*").u * 2 puts a.inspect_names <U000024>DOLLAR SIGN <U01D7D9>MATHEMATICAL DOUBLE-STRUCK DIGIT ONE <U000024>DOLLAR SIGN <U01D7D9>MATHEMATICAL DOUBLE-STRUCK DIGIT ONE puts "abracadabra".u.gsub(/(b)/.U, a) abbracadabbra \ 3. One can create URegexp using global Kernel#ure function, Regexp#U, Regexp#to_u, or from UString using URegexp.new, e.g: /pattern/.U =~ "string".u 4. There are differences about Regexp and URegexp multiline matching options: t = "text\ntest" # ^,$ handling : URegexp multiline <-> Ruby default t.u =~ ure('^\w+$', URegexp::MULTILINE) => #<UMatch:0xf6f7de04 @ranges=[0..3], @cg=[\u0074\u0065\u0078\u0074]> t =~ /^\w+$/ => 0 # . matches \n : URegexp DOTALL <-> /m t.u =~ ure('.+test', URegexp::DOTALL) \ => #<UMatch:0xf6fa4d88 ... t.u =~ /.+test/m 5. UMatch.range(idx) returns range for capturing group idx. This range is in codeunits. === References 1. ICU Official Homepage http://ibm.com/software/globalization/icu/ 2.
