This gem provide lazy access method like array to IO object.
A Seq is created with an array, and optionally a number of elements to return, an offset to start at and a default item to return when ended. Call #next to return the next item. A Seq::Random will return randomly selected elements from the array. A Seq::Lazy will lazily evaluate a block to get the next element.
A DataMapper adapter for Amazon's SimpleDB service. Features: * Full set of CRUD operations * Supports all DataMapper query predicates. * Can translate many queries into efficient native SELECT operations. * Migrations * DataMapper identity map support for record caching * Lazy-loaded attributes * DataMapper Serial property support via UUIDs. * Array properties * Basic aggregation support (Model.count("...")) * String "chunking" permits attributes to exceed the 1024-byte limit Note: as of version 1.0.0, this gem supports supports the DataMapper 0.10.* series and breaks backwards compatibility with DataMapper 0.9.*.
== Synopsys Ruby Enumerable extension. Main idea is lazy computations within enumerators. == Usage Install as a gem: sudo gem install deferred_enum This gem introduces DeferredEnumerator class: ary = [1, 2, 3, 4] deferred = ary.defer # #<DeferredEnumerator: [1, 2, 3, 4]:each> DeferredEnumerator brings some optimizations to all?, any? and none? predicates deferred.all?(&:even?) # Will stop iteration after first false-result = 1 iteration deferred.none?(&:even?) # 2 iterations deferred.any?(&:even?) # 2 iterations It also introduces lazy versions of Enumerable's #select, #map and #reject methods deferred.map { |i| i + 1 } # #<DeferredEnumerator: #<Enumerator::Generator>:each> deferred.select { |i| i.even? } # #<DeferredEnumerator: #<Enumerator::Generator>:each> deferred.reject { |i| i.odd? } # #<DeferredEnumerator: #<Enumerator::Generator>:each> So you can safely chain your filters, they won't be treated as arrays: deferred.map(&:succ).select(&:even?) # #<DeferredEnumerator: #<Enumerator::Generator>:each> You can build chains of Enumerables: deferred.concat([2]).to_a # [1, 2, 3, 4, 2] Or append elements to the end of enumerator: deferred << 2 You can even remove duplicates from enumerator, though this operation can be tough: deferred.uniq # #<DeferredEnumerator: #<Enumerator::Generator>:each> There are many other methods in DeferredEnumerator, please refer to documentation.
