Pipe operators, available in magrittr, dplyr, and other R packages, process a data-object using a sequence of operations by passing the result of one step as input for the next step using infix-operators rather than the more typical R method of nested function calls.

Note that the intended aim of pipe operators is to increase human readability of written code. See Remarks section for performance considerations.

The pipe | character is used to apply pipes in Angular 2. Pipes are very similar to filters in AngularJS in that they both help to transform the data into a specified format.

pip is the most widely-used package manager for the Python Package Index, installed by default with recent versions of Python.

The asset pipeline provides a framework to concatenate and minify or compress JavaScript and CSS assets. It also adds the ability to write these assets in other languages and pre-processors such as CoffeeScript, Sass and ERB. It allows assets in your application to be automatically combined with assets from other gems. For example, jquery-rails includes a copy of jquery.js and enables AJAX features in Rails.

PowerShell introduces an object pipelining model, which allows you to send whole objects down through the pipeline to consuming commandlets or (at least) the output. In contrast to classical string-based pipelining, information in piped objects don't have to be on specific positions. Commandlets can declare to interact with Objects from the pipeline as input, while return values are sent to the pipeline automatically.

Pipes are a mechanism for unidirectional interprocess or interthread communication within the scope of a single machine. Logically, a pipe consists of two connected termini, one to which data can be written, and another from which that data can subsequently be read, with a data buffer between such that writes and reads are not required to be synchronous. Pipes should be distinguished from shell pipelines, which are an application of pipes.

An Item Pipeline is a python class that overrides some specific methods and needs to be activated on the settings of the scrapy project.

The angular-cli tool can help you to scaffold different parts of an angular application (components, directives, pipes, services, classes, guards, interfaces, enums and modules).
