    Citrus

    Citrus

    Citrus

    Framework for automated integration tests supporting a wide range of message protocols and data formats! In a typical test scenario the system under test is running on a test infrastructure while interacting with Citrus over various messaging transports. During the test Citrus is able to act on both sides as client and consumer exchanging real request/response messages over the wire. With each test step you can validate the exchanged messages with expected control data including message headers, attachments and body content (e.g. XML, Json, ...). The test provides a Java fluent API to specify the test logic and is fully automated. The repeatable test is nothing but a normal JUnit or TestNG test and can easily run as integration test in a CI/CD pipeline. Kamelets represent Camel-K route snippets that act as standardized event sources and sinks in an event driven architecture.

    Crystal

    Crystal

    Crystal

    Crystal’s syntax is heavily inspired by Ruby’s, so it feels natural to read and easy to write, and has the added benefit of a lower learning curve for experienced Ruby devs. Crystal is statically type-checked, so any type errors will be caught early by the compiler rather than fail on runtime. Moreover, and to keep the language clean, Crystal has built-in type inference, so most type annotations are unneeded. All types are non-nilable in Crystal, and available variables are represented as a union between the type and nil. As a consequence, the compiler will automatically check for null references in compile time. Crystal’s answer to metaprogramming is a powerful macro system, which ranges from basic templating and AST inspection to types inspection and running arbitrary external programs.

    CoffeeScript

    CoffeeScript

    CoffeeScript

    Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. The golden rule of CoffeeScript is: “It’s just JavaScript.” The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly from CoffeeScript (and vice-versa). The compiled output is readable, pretty printed, and tends to run as fast or faster than the equivalent handwritten JavaScript. Most modern JavaScript features that CoffeeScript supports can run natively in Node 7.6+, meaning that Node can run CoffeeScript’s output without any further processing required. This list may be incomplete, and excludes versions of Node that support newer features behind flags; please refer to node.green for full details. You can run the tests in your browser to see what your browser supports.

    BLooP

    Welcome to the Dictionary of Programming Languages, a compendium of computer coding methods assembled to provide information and aid your appreciation for computer science history. BLooP was a very simple recursive block structured language invented by Douglas Hofstadter for his book Godel, Escher, Bach. It features simple subroutine structure, very simple number and boolean handling, and recursion. The interesting aspect of BLooP was that it offered only bounded loop constructs, and was therefore incapable of expressing certain general recursive computations.

    Bash

    Bash is a free software Unix shell and command language. It has become the default login shell for most Linux distributions. In addition to being available on Linux systems, a version of Bash is also available for Windows through the Windows Subsystem for Linux. Bash is the default user shell in Solaris 11 and was the default shell in Apple macOS from version 10.3 until the release of macOS Catalina, which changed the default shell to zsh. Despite this change, Bash remains available as an alternative shell on macOS systems. As a command processor, Bash allows users to enter commands in a text window that are then executed by the system. Bash can also read and execute commands from a file, known as a shell script. It supports a number of features commonly found in Unix shells, including wildcard matching, piping, here documents, command substitution, variables, and control structures for condition testing and iteration. Bash is compliant with the POSIX shell standards.
