HCDL also known as the Hypercontent Distribution Language, is the standard binary language used in Web communications to end users. It is normally assembled on the server side using THCDL (textual HCDL), CSS, and Q-WebAssembly.

Filename Extension: .hcdl

MIME type: text/hcdl

Type code: TEXT

Some advantages of HCDL include:

Lightweight
Highly optimised
Reduced request load and page loading time due to preprocessing on the server side
On-the-fly parsing
Extreme modularity with numerous libraries
Native support in Q-Language-written Web browsers

Language

Example

HCDL
meta>
    title>Example Title;
<
header>
    header-l1>Title;
<
content>
    parag>attr>.red:.extra-class;HLLO
EXTRA TEXT;
    list>attr>unordered:.red;
        list-entry>whatever bold>text;;
    <
<

> a < — behaves like a standard opening tag. It begins a block element.

For self-closing tags that contain only text, you can omit the <. This simplifies the syntax for simple text insertions.

The difference between >; and > <:

>; expects text content or additional inline HCDL.

> < expects only more nested HCDL elements, no plain text.

: is used to separate attributes within a tag.

.red {
    color: red;
}

.extra-class {
    text-align: center;
}

fun onLoad() {
     Hcdl.selectElement(".extra-class").outer = parag {
         +"hello"
     }
}

The previous section would compile to:

Hypercontent Distribution Protocol

The Hypercontent Distribution Protocol (HCDP) is an application-layer protocol (Layer 7 in the Internet protocol suite model) designed for distributed, collaborative, hypermedia information systems. As the evolutionary successor to the classical Hypertext Transfer Protocol (HTTP), HCDP forms the backbone of modern data communication across the World Wide Web, with support for advanced hypercontent structures, documents embedded with dynamic hyperlinks, rich media, and interactive references easily accessible via clicks, taps, or neural input (in compatible environments).

HCDP introduces compatibility with the Hypercontent Distribution Language (HCDL), a next-generation front-end development language. It enables fluid integration of multimedia elements, AI-driven UI components, and cross-platform accessibility in a decentralized environment (THOR Browser).

HCDP operates as a request–response protocol under the client–server model:

A client, typically a web browser or HCDL-capable interface, initiates a connection and sends an HCDP request.

A server, running a daemon or process hosting one or more web applications, processes the request and returns an HCDP response.

This response contains:

Completion status codes (e.g., 200 OK, 404 Not Found, etc.)

Optional payloads such as HCDL files, media content, or server-generated data.

HCDP supports both static and dynamic content, allowing developers to deliver immersive, data-rich user experiences.
