== 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.

== README.md: #ScheduledResource This gem is for displaying how things are used over time -- a schedule for a set of "resources". You can configure the elements of the schedule and there are utilities and protocols to connect them: - Configuration (specification and management), - Query interfaces (a REST-like API and internal protocols to query the models), and - A basic Rails controller implementation. We have a way to configure the schedule, internal methods to generate the data, and a way to retrieve data from the client. However this gem is largely view-framework agnostic. We could use a variety of client-side packages or even more traditional Rails view templates to generate HTML. In any case, to get a good feel in a display like this we need some client-side code. The gem includes client-side modules to: - Manage <b>time and display geometries</b> with "infinite" scroll along the time axis. - <b>Format display cells</b> in ways specific to the resource models. - <b>Update text justification</b> as the display is scrolled horizontally. ## Configuration A **scheduled resource** is something that can be used for one thing at a time. So if "Rocky & Bullwinkle" is on channel 3 from 10am to 11am on Saturday, then 'channel 3' is the <u>resource</u> and that showing of the episode is a <u>resource-use</u> block. Resources and use-blocks are typically Rails models. Each resource and its use-blocks get one row in the display. That row has a label to the left with some timespan visible on the rest of the row. Something else you would expect see in a schedule would be headers and labels -- perhaps one row with the date and another row with the hour. Headers and labels also fit the model of resources and use-blocks. Basic timezone-aware classes (ZTime*) for those are included in this gem. ### Config File The schedule configuration comes from <tt>config/resource_schedule.yml</tt> which has three top-level sections: - ResourceKinds: A hash where the key is a Resource and the value is a UseBlock. (Both are class names), - Resources: A list where each item is a Resource Class followed by one or more resource ids, and - visibleTime: The visible timespan of the schedule in seconds. The example file <tt>config/resource_schedule.yml</tt> (installed when you run <tt>schedulize</tt>) should be enough to display a two-row schedule with just the date above and the hour below. Of course you can monkey-patch or subclass these classes for your own needs. ### The schedule API The 'schedule' endpoint uses parameters <tt>t1</tt> and <tt>t2</tt> to specify a time interval for the request. A third parameter <tt>inc</tt> allows an initial time window to be expanded without repeating blocks that span those boundaries. The time parameters _plus the configured resources_ define the data to be returned. ### More About Configuration Management The <b>ScheduledResource</b> class manages resource and use-block class names, id's and labels for a schedule according to the configuration file. A ScheduledResource instance ties together: 1. A resource class (eg TvStation), 2. An id (a channel number in this example), and 3. Strings and other assets that will go into the DOM. The id is used to - select a resource _instance_ and - select instances of the _resource use block_ class (eg Program instances). The id _could_ be a database id but more often is something a little more suited to human use in the configuration. In any case it is used by model class method <tt>(resource_use_block_class).get_all_blocks()</tt> to select the right use-blocks for the resource. A resource class name and id are are joined with a '_' to form a tag that also serves as an id for the DOM. Once the configuration yaml is loaded that data is maintained in the session structure. Of course having a single configuration file limits the application's usefulness. A more general approach would be to have a user model with login and configuration would be associated with the user. ## Installation Add this line to your application's Gemfile: ```ruby gem 'scheduled_resource' ``` And then execute: $ bundle Or install it yourself as: $ gem install scheduled_resource Then from your application's root execute: $ schedulize . This will install a few image placeholders, client-side modules and a stylesheet under <tt>vendor/assets</tt>, an example configuration in <tt>config/resource_schedule.yml</tt> and an example controller in <tt>app/controllers/schedule_controller.rb</tt>. Also, if you use $ bundle show scheduled_resource to locate the installed source you can browse example classes <tt>lib/z_time_*.rb</tt> and the controller helper methods in <tt>lib/scheduled_resource/helper.rb</tt> ## Testing This gem also provides for a basic test application using angularjs to display a minimal but functional schedule showing just the day and hour headers in two different timezones (US Pacific and Eastern). Proceed as follows, starting with a fresh Rails app: $ rails new test_sr As above, add the gem to the Gemfile, then $ cd test_sr $ bundle $ schedulize . Add lines such as these to <tt>config/routes.rb</tt> get "/schedule/index" => "schedule#index" get "/schedule" => "schedule#schedule" Copy / merge these files from the gem source into the test app: $SR_SRC/app/views/layouts/application.html.erb $SR_SRC/app/views/schedule/index.html.erb $SR_SRC/app/assets/javascripts/{angular.js,script.js,controllers.js} and add <tt>//= require angular</tt> to application.js just below the entries for <tt>jquery</tt>. After you run the server and browse to http://0.0.0.0:3000/schedule/index you should see the four time-header rows specified by the sample config file. ## More Examples A better place to see the use of this gem is at [tv4](https://github.com/emeyekayee/tv4). Specifically, models <tt>app/models/event.rb</tt> and <tt>app/models/station.rb</tt> give better examples of implementing the ScheduledResource protocol and adapting to a db schema organized along somewhat different lines. ## Contributing 1.
