A sane API for working with datatables data structures and javascript output

Reins is a ruby gem that automates the creation of javascript controllers that match the structure of your rails controllers. This includes passing custom data to the JS controllers from the server.

Well, who needed another serialization format? Not me, but that's what I've made. Ruby Object Notation (Ron) is a textual format for the representation of Ruby data structures. It's somewhat like YAML, XML, or (most of all) JSON. However, since it is defined entirely within and as a subset of Ruby, it has the slick property that Ron expressions are legal Ruby. Thus it is very like JSON, except that it's Ruby-centered instead of being JavaScript-centered. Another way to look at Ron is as a purely declarative language for creating (almost) any type of Ruby data structure.

RSence is a different and unique development model and software frameworks designed first-hand for real-time web applications. RSence consists of separate, but tigtly integrated data- and user interface frameworks. RSence could be classified as a thin server - thick client system. Applications and submobules are installed as indepenent plugin bundles into the plugins folder of a RSence environment, which in itself is a self-contained bundle. A big part of RSence itself is implemented as shared plugin bundles. The user interface framework of RSence is implemented in high-level user interface widget classes. The widget classes share a common foundation API and access the browser's native API's using an abstracted event- and element layer, which provides exceptional cross-browser compatibility. The data framework of RSence is a event-driven system, which synchronized shared values between the client and server. It's like a realtime bidirectional form-submission engine that handles data changes intelligently. On the client, changed values trigger events on user interface widgets. On the server, changed values trigger events on value responder methods of server plugin modules. It doesn't matter if the change originates on client or server, it's all synchronized and propagated automatically. The server framework is implemented as a high-level, modular data-event-driven system, which handles delegation of tasks impossible to implement using a client-only approach. Client sessions are selectively connected to other client sessions and legacy back-ends via the server by using the data framework. The client is written in Javascript and the server is written in Ruby. The client also supports CoffeeScript for custom logic. In many cases, no custom client logic is needed; the user interfaces can be defined in tree-like data models. By default, the models are parsed from YAML files, and other structured data formats are possible, including XML, JSON, databases or any custom logic capable of producing similar objects. The server can connect to custom environments and legacy backends accessible on the server, including software written in other languages.

Glimmer DSL for Web (Ruby in the Browser Web Frontend Framework) enables building Web Frontends using Ruby in the Browser, as per Matz's recommendation in his RubyConf 2022 keynote speech to replace JavaScript with Ruby. It aims at providing the simplest, most intuitive, most straight-forward, and most productive frontend framework in existence. The framework follows the Ruby way (with DSLs and TIMTOWTDI) and the Rails way (Convention over Configuration) in building Isomorphic Ruby on Rails Applications. It provides a Ruby HTML DSL, which uniquely enables writing both structure code and logic code in one language. It supports both Unidirectional (One-Way) Data-Binding (using <=) and Bidirectional (Two-Way) Data-Binding (using <=>). Dynamic rendering (and re-rendering) of HTML content is also supported via Content Data-Binding. Modular design is supported with Glimmer Web Components, Component Slots, and Component Custom Event Listeners. And, a Ruby CSS DSL is supported with the included Glimmer DSL for CSS. Many samples are demonstrated in the Rails sample app (there is a very minimal Standalone [No Rails] sample app too). You can finally live in pure Rubyland on the Web in both the frontend and backend with Glimmer DSL for Web! This gem relies on Opal Ruby.

== 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 &lt;b&gt;time and display geometries&lt;/b&gt; with "infinite" scroll along the time axis. - &lt;b&gt;Format display cells&lt;/b&gt; in ways specific to the resource models. - &lt;b&gt;Update text justification&lt;/b&gt; 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 &amp; Bullwinkle" is on channel 3 from 10am to 11am on Saturday, then 'channel 3' is the &lt;u&gt;resource&lt;/u&gt; and that showing of the episode is a &lt;u&gt;resource-use&lt;/u&gt; 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 &lt;tt&gt;config/resource_schedule.yml&lt;/tt&gt; 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 &lt;tt&gt;config/resource_schedule.yml&lt;/tt&gt; (installed when you run &lt;tt&gt;schedulize&lt;/tt&gt;) 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 &lt;tt&gt;t1&lt;/tt&gt; and &lt;tt&gt;t2&lt;/tt&gt; to specify a time interval for the request. A third parameter &lt;tt&gt;inc&lt;/tt&gt; 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 &lt;b&gt;ScheduledResource&lt;/b&gt; 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 &lt;tt&gt;(resource_use_block_class).get_all_blocks()&lt;/tt&gt; 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 &lt;tt&gt;vendor/assets&lt;/tt&gt;, an example configuration in &lt;tt&gt;config/resource_schedule.yml&lt;/tt&gt; and an example controller in &lt;tt&gt;app/controllers/schedule_controller.rb&lt;/tt&gt;. Also, if you use $ bundle show scheduled_resource to locate the installed source you can browse example classes &lt;tt&gt;lib/z_time_*.rb&lt;/tt&gt; and the controller helper methods in &lt;tt&gt;lib/scheduled_resource/helper.rb&lt;/tt&gt; ## 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 &lt;tt&gt;config/routes.rb&lt;/tt&gt; get "/schedule/index" =&gt; "schedule#index" get "/schedule" =&gt; "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 &lt;tt&gt;//= require angular&lt;/tt&gt; to application.js just below the entries for &lt;tt&gt;jquery&lt;/tt&gt;. 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 &lt;tt&gt;app/models/event.rb&lt;/tt&gt; and &lt;tt&gt;app/models/station.rb&lt;/tt&gt; give better examples of implementing the ScheduledResource protocol and adapting to a db schema organized along somewhat different lines. ## Contributing 1.
