Qore (programming language)

Qore is an interpreted, high-level, general-purpose, garbage collected dynamic programming language, featuring support for code embedding and sandboxing with optional strong typing and a focus on fundamental support for multithreading and SMP scalability.
Qore is unique because it is an interpreted scripting language with fundamental support for multithreading (meaning more than one part of the same code can run at the same time), and additionally because it features automatic memory management (meaning programmers do not have to allocate and free memory explicitly) while also supporting the RAII idiom with destructors for scope-based resource management and exception-safe programming. This is due to Qore's unique prompt collection implementation for garbage collection.
Qore Scripts.
Qore scripts typically have the following extensions:
Executable Qore scripts on Unix-like operating systems will typically start with a hashbang to specify the filename of the interpreter as follows:
codice_4
Syntax.
Qore syntax is similar to and inspired from the following programming languages:
Data Types.
Basic types include: codice_23, codice_24, codice_25, codice_26, codice_27, codice_28, codice_29, codice_30 (associative arrays), and codice_31, as well as code codice_32 for code used as a data type.
Complex types are also supported such as codice_33, codice_34, codice_35 as well as type-safe hashes.
Multithreading.
Despite being an interpreted language, Qore was designed to support multithreading as a fundamental design principle. All elements of Qore are thread-safe, and the language in general has been designed with SMP scalability in mind. Because all elements of the language were designed to support multithreading, Qore programs and scripts do not have to limit themselves to a subset of Qore's functionality, which is also why there is no Global interpreter lock in Qore.
Threading functionality in Qore is provided by the operating system's POSIX threads library.
Garbage Collection.
Qore features a unique garbage collection approach called prompt collection that allows destructors to be run immediately when objects go out of scope, even if they have recursive references back to themselves. This allows for Qore to support the RAII idiom and also perform garbage collected automatic memory management.
Support for Code Embedding and Sandboxing.
Qore was designed to support embedding and sandboxing logic in applications; this also applies to applications written in Qore as well as applications using the Qore library's public C++ API. By using the codice_36 class which represents a logic container with sandboxing controls, discrete objects can be created and destroyed at runtime containing embedded code to extend or modify the behavior of your application in user-defined ways.
Runtime Library.
Qore's standard runtime library supports data mapping, APIs for communicating with databases (including high-level APIs for SQL operations, schema management, and DBA actions), client APIs and server infrastructure implementations for many protocols including HTTP, REST (with REST schema validation/code generation including Swagger support), client/server SOAP support (including code and message generation), WebSocket, RPC protocols, generic connector APIs, generic data mapping APIs, and many file format and file- and data-exchange protocols and more.
Testing.
Qore supports testing through the QUnit module which facilitates automated testing and Continuous integration processes for code written in Qore.
Availability.
Qore's Git (software) repository is hosted on GitHub. Binary packages are available as RPM s, in MacPorts and in FreeBSD Ports as well as for other operating systems, including Microsoft Windows; see General Source and Download Info on the Qore wiki for more information.
