. Introduction

Rocko programming language A modern, expressive and versatile language is designed with the purpose of empowering developers to write clean, flexible and powerful codes. Although he began his life as a long wait as “Pearl 6”, Rako has increased its own identity-a free language that maintains Pearl’s creative spirit, while presenting a new context about programming in the 21st century. Basically, Raku has adopted the developer’s freedom philosophy: it supports multiple parables, it has a rich type of system, and provides modern tools for text processing, harmony and mattressing. Instead of becoming a language for just a niche, Rocko’s goal is to be a “toolbox for thinking”, encourage experience and give programmers a number of ways to express their ideas.

In this article, we will dive at the beginning of the rock, discover its specified features, and consider such projects where it shines.

. A short date

Raku’s journey is one of the perseverance, rehabilitation, and community -driven innovation. The story begins in 2000, when the Pearl Creator Larly Was called at that time announced his plans Pearl 6. Instead of a simple update in Pearl 5, its concept was considered bold language: an opportunity to revise programming methods for a new era of computing. Over the next two decades, hundreds of partners worked to re -design the language, made in the effects of functional programming, object -based design, and the effects of modern types, while the famous slogans of Pearl remained in accordance with the effects of the system. “There are more than one way to do this.”

As the language was developed, it became clear that its scope and vision went beyond the next version of Pearl. To recognize this freedom, the community chose a new name, RockIn 2019. By renaming this name, Raku was recognized as a separate language and without the invitation for the developers without the goods to compare it completely with Pearl. Today, while maintaining a unique balance of innovation and tradition, it continues to develop under the responsibility of an active, passionate community.

. Key features of Rocko

Let’s take a look at some of the technical aspects of the language. The following are some of the main features of the rico.

!! Multi Paradim Support

Rocko supports multiple programming parables, including:

• Method (Classic Step by Step Code)
• Based on Object (Class, items, methods)
• Functionary (First class functions, high order functions)

This flexibility allows you to write easy scripts or large -scale applications using a parable that best fits your needs.

# Procedural
say "Hello, Raku!";

# Object-Oriented
class Animal {
    has Str $.name;
    method speak { say "$.name makes a sound." }
}
Animal.new(name => "Cat").speak;

# Functional
my @nums = (1, 2, 3, 4);
say @nums.map(* * 2);

Output:

!! Harmony and harmony

In modern computing, harmony is rapidly important, and the rock solves this need with built -in construction. Similar PromiseFor, for, for,. startFor, for, for,. awaitAnd Supply Make it easy to write unrelated codes.

For example, you can start a work in the background and wait for the results.

my $promise = start {
    sleep 2;
    "Task done"
};
say await $promise;

!! Regular expression and grammar

Rocko increases traditional regular expression with governance analysis. In Rocko, regular expression is a first -class feature, and you can also create a full grammar for more advanced text processing.

Here is an example of a grammar that analyzes simple CSV data.

grammar CSV {
    token TOP { * }
    token row {  ** ',' \n? }
    token cell { <-(,\n)>+ }
}

!! Strong type of system

Rocko offers a rich and expressive type of system that supports both stable and dynamic typing. You can clearly declare the types or let the rock evaluate them. This gradual typing approach allows you to use the types only wherever needed, which helps to strengthen the code and make it easier to manage.

# Static typing
sub greet(Str $name) {
    say "Hello, $name!";
}

# Works fine
greet("Alice");

# Type check error at runtime
greet(42);

!! Metaprograming

Rocko provides developers with the latest metaprograming capabilities, enables programs to produce, inspect and modify the code while practicing practical clothes. It also supports self -identification, dynamic code diagnosis, and language syntax and behaviors.

Key Metrogramming Tools in Rocko include:

• EVAL: Dynamic evaluation of code wires at the time time
• Disorder: Test types, methods, signatures, attributes and more

Here is an easy example EVAL To describe Subrotine at the time of run -time:

# Define and call a function at runtime
EVAL 'sub dynamic() { say "This was defined dynamically!" }';
dynamic();

Output:

This was defined dynamically!

!! Multiple Dispatch

Rocko receives built -in support for multiple dispatchs, which means that you can create a number of versions of the same function, where each version handles different types or number of arguments. This makes your code clear and safe, as you can handle each matter separately. At the time of the run -time, Rako automatically selects the function version that is best found in the arguments provided.

# Define multiple versions of the same function
multi greet(Str $name) {
    say "Hello, $name!";
}

multi greet(Int $times) {
    say "Hello!" x $times;
}

greet("Raku");
greet(3);

Output:

Hello, Raku!
Hello!Hello!Hello!

!! Junction

A junction is a construction that represents numerous potential values ​​at the same time. You can think of it as a logical super position of values ​​that behaves as if it are all values ​​of it simultaneously.

There are four main types of junctions in Rocko:

• any: If any values ​​meet the condition then the truth returns
• all: Only if the truth is returned when all values ​​meet the condition
• none: If no one fulfills the prerequisite, the truth should come back
• one: If a value is fulfilled at all, the truth returns

my $color="red";

if $color eq any('red', 'green', 'blue') {
    say "Valid color!";
}

my $score = 95;

if $score > all(80, 85, 90) {
    say "Excellent score!";
}

# Check if exactly one condition is true
say one(True, False, False);
say one(True, True, False);

Output:

. Tooling and ecosystem

Rocko is a combination of a growing environmental system and modern development tools that enjoy it in practice and to work.

Key tools and components in the Rocko Environmental System include:

• Rockwido: Official and most used roco compiler, actively retained and regularly updated
• Zipper: A module manager for Rocko, used to install, test and manage dependent
• Read.: An interactive shell that allows a sharp, real -time experience with the rocky code
• Rocksty: A abstract syntax tree system is being introduced in the language to support code generation and transformation tools
• IDE Support: Plugin and syntax of Rocko are available for popular editors like Vs. codeWim, Amos, and others

. Use matters and requests

Rocko’s capacity and expression makes it a great choice for extensive programming tasks.

Common use cases include:

• Scripting and automation: Comprehensive syntax and built -in shell friendly features of Rocko make it the best of writing scripts that automatically automate system tasks, file processing, or DOOPs pipelines.
• Data processing and text diamond: With its advanced regex engine, grammar, and unicode support, Rico is taking the lead in analyzing and changing data from various sources and formats.
• Tongue and compiled design: Rocko grammar system, rocking, and metaprograming features make it an excellent playground for the design of new languages, interpreters, or code transformation tools.
• Prototy -typing and experience: Thanks to its interactive replica and flexible type system, the best for checking rock ideas, teaching programming concepts, or building internal DSL

. Wrap

Rocko stands as a proof when a programming language is allowed to grow physically, not only the technical requirement but also through creativity and philosophy. It combines the practice of scripting languages ​​with the sophistication of modern types of systems, harmony models, and text processing capabilities, which is immediately equally suitable for the script and the long -term projects once. Although it may not yet be the mainstream of the mainstream of languages ​​like Azigar or JavaScript, the rock offers something wonderful: a language that encourages experience, welcomes several programming styles, and permanently expands the limits to the extent to which coding is. For developers who enjoy finding new parables and flexibility, Rocko not only represents a device but also represents a developing environmental system and a community that develops on innovation.

Recently. Rocky is less about to replace current languages ​​and more about presenting a new lens through which to think about self -programming.
