SIML Compiler (simlc)

A fast, lightweight C++ reference parser and AST builder implementing the full SIML (Simplified Interface Markup Language) Specification.

Written in standard C++ with zero external dependencies.

Building

Requires a C++ compiler with C++20/C++23 support and CMake 3.20+.

# Configure
cmake -B build -DCMAKE_BUILD_TYPE=Release

# Build library and tests
cmake --build build

# Run test suite
ctest --test-dir build --output-on-failure

Quick Example

#include <iostream>
#include "Lexer/Source.h"
#include "Lexer/Lexer.h"
#include "Node/Node.h"

int main() {
    std::string code = R"(
        .title: "Sample View";
        .enabled: true;
        
        Button {
            .width: 120;
            .height: 40;
            .label: "Submit";
        };
    )";

    SIML::Source source(code);
    SIML::Lexer lexer(source);

    auto result = SIML::NodeObject::parseAsGlobalNode(lexer);
    if (result.hasError()) {
        std::cerr << "Parsing failed: " << result.error().m_message << "\n";
        return 1;
    }

    // Access parsed AST
    std::cout << "Parsed AST successfully:\n" << **result << "\n";
    return 0;
}
