Our lives couldn't have been simpler and smarter than today. Thanks to the programming languages that have proved their potential in every segment- home appliances, automobile, financing, retail, healthcare, and so on. Our lives are now directly or indirectly dependent on digital assets backed by smart programming languages. 

All the popular programming languages like Python, Kotlin, Java, NodeJS, Swift have already impressed us lately. And now, here's a new programming language that has recently made its space in the programming language list: Qore. Since it's a whole new term for all of us, let's get started with Qore's history of how it evolved in the digital world. 

Evolution of Qore

Developed and designed by David Nichols, Qore is an actively used programming language which was initially created in the year 2006. It got its stable release- 0.9.4.2 in March 2020. Qore is a high-level, interpreted, garbage-collected dynamic programming language that emphasizes fundamental support for multithreading and SMP scalability. It is an interpreted scripting language with the basic support of multithreading, features automatic memory management, and supports RAII idiom for scope-based resource management and exception-safe programming. All these unique features are possible in Qore due to the implementation of garbage collection.

Understanding Qore Syntax & Scripts

Qore has a syntax that is simply a combination of the popular programming languages that include- Java, Perl, C++, D, and Haskell. For the ones who know C or C++, they will easily understand the syntax of Qore and realize that it is quite similar to C/C++.

And when it comes to the Qore Scripts, there are majorly three extensions that are covered under Qore Scripts: .q (for Qore scripts), .qm (for Qore user modules), and .qtest (for Qore test scripts). On Unix-like OS, the executable Qore scripts begin with a hashtag for specifying the interpreter's filename as: #!/usr/bin/env qore

Highlights of Qore

As of now, there are numerous reasons that convince developers and industry leaders to count on Qore. In the coming time, we can expect a lot of other benefits and global adoption of the popular programming language. Qore is broadly designed for enterprise use with- optional strong typing and exception handling, multithreading and thread-safe programming, automatic memory management and c++-style destructors, code embedding, and sandboxing controls.

The major highlights that make Qore a significant and worth trying programming language include:

  • Fundamental support for data serialization, interfacing, file-based & message-based data transfers.
  • Operates seamlessly on macOS, Unix/Linux, and Windows.
  • Fundamental support for test-driven development.
  • Permissive open source license.
  • Advanced APIs for schema management, SQL generation, and DBA activities.

Thread safety & SMP scalability

Qore elements are totally thread-safe and the language is designed while ensuring SMP scalability. The internal design and implementation of Qore support multithreaded performance instead of single-threaded performance. So, this is a plus point of Qore programming language where we can get an efficient and stable execution platform. Qore even comprises optimizations that are specifically designed to minimize the number of SMP cache invalidations that offer a substantial performance boost on SMP machines. 

Modules

Qore comes equipped with around 60 modules that have advanced features like APIs for networking, HTTP server, unit testing, working with MySQL, PostgreSQL and SQLite, and a lot more. Apart from this, there are other 20 modules offered that are in source form (user) or compiled C++ (binary). Qore supports Posix threads and it has a wide segment of classes for managing threading objects that include counters, locks, gates, queues, and mutexes.

Embedded logic support

Qore even supports embedding logic in apps that even includes the apps that are written in Qore and apps that use the Qore library's public C++ API. Discrete objects can be developed and destroyed with the help of the Program class, which even permits the abilities of embedded code to be arbitrarily restricted.

Garbage collection

Qore is equipped with a unique garbage collection approach, which is known as a prompt collection. It enables destructors to be operated instantly once the objects go out of scope. It enables Qore to support the RAII idiom and carry out garbage collected automatic memory management.

Function & Class Library

Qore has a set of functionalities that include thread synchronization, POSIX-compliant command-line parsing, strong encryption and digest calculation, socket, HTTP, support for dynamic embedded application logic, higher-level protocol communication.

Database Integration and DBI Layer

Qore has an in-built database integration that helps in retrieving, manipulating, and comparing data consistently from heterogeneous database types. It has a database independent interfacing (DBI) layer, offering a standard interface for Qore programs for accessing all sorts of the database that are supported by a Qore DBI driver.

Final Thoughts

Qore, as a scripting language, can overrule Python, C++, or Java utilities since there is no need to compile it. In the coming time ahead, Qore compiler will also be released for compilation. So, there's a lot we can expect from Qore programming language that will make a reputable name and wide adoption in the digital landscape.
