Markup v0.1.0

Markup — Document Authoring Language

Write documents, not HTML. Every construct follows the same {tag "content"} pattern — variables, conditionals, iteration, and component definitions all use the same syntax. A Markup document compiles to clean, semantic HTML.

Highlights

• Single-syntax design — everything is {tag "content"}, no mode switches, no special cases, no ambiguous parsing contexts
• Quoted string delimiters — content is delimited by "...", so the parser knows exactly what to preserve
• Turing-complete logic — variables, conditionals, iteration, recursion, and reusable components are first-class constructs
• Expression evaluator with pipes — {=expr | filter} interpolation with chainable transforms
• Built-in functions — string, math, comparison, collection, HTML, and type operations
• Data binding — pass JSON data and access it from templates with {=data.path} interpolation
• DLL with flat C-style API — ship as a single Markup.dll, integrate from Delphi, C/C++, or any FFI-capable language
• Extensibility — register custom tag handlers and expression functions at runtime
• Configurable options — pretty-print output, strict mode, HTML sanitization, unknown tag handling, and safety limits per engine instance
• Include system — file includes with data attributes and circular reference detection
• File output — render directly to .html files with optional browser launch via markup_convert_to_file

Testbed demos:

• Formatting — headings, inline text, lists, tables, code blocks, sections, layout, links & media, quotes, callouts, details, forms, void tags
• Logic — variables, conditionals, iteration, components, pipes, eval, raw HTML, meta tags
• Built-in functions — string, math, comparison, collection, HTML, type
• API — convert-to-file, include paths
• Extensibility — custom tags, custom functions, status handler

Each demo produces a standalone HTML file in bin/output/ demonstrating the feature set.

Quick start (Delphi):

uses
  Markup;

var
  LEngine: TMuEngine;
  LHtml: PAnsiChar;
begin
  LEngine := markup_create();
  try
    LHtml := markup_convert(LEngine,
      PAnsiChar(UTF8Encode(
        '{h1 "Hello, Markup!"}{p "Write Documents, Not HTML."}')),
      nil);
    try
      WriteLn(string(UTF8String(LHtml)));
    finally
      markup_free(LHtml);
    end;
  finally
    markup_destroy(LEngine);
  end;
end;

Quick start (C/C++):

#define MARKUP_IMPLEMENTATION
#include "Markup.h"

int main(void) {
    if (!markup_load("Markup.dll")) return 1;

    MuEngine engine = markup_create();
    char* html = markup_convert(engine,
        "{h1 \"Hello, Markup!\"}{p \"Write Documents, Not HTML.\"}",
        NULL);
    printf("%s\n", html);
    markup_free(html);
    markup_destroy(engine);

    markup_unload();
    return 0;
}

Documentation: See docs/Specs.md for the language specification, docs/API.md for the complete DLL API reference, and docs/User.md for the practical usage guide.

Requirements: Windows 10/11 x64. Building from source requires Delphi 12.x or higher.
