Kryon-C

A UI system implemented in C with the Kryon language for declarative UI development.

Overview

Kryon-C provides:

KRY Language Compiler - Compile .kry source files to .krb binary format
Runtime System - Execute Kryon applications with element trees
CLI Tools - Command line interface for compilation and execution
UI Elements - Text, Button, Container, Column, Row, Dropdown, etc.
Build Scripts - Convenient development workflow

Building

Prerequisites

CMake 3.15+
GCC or Clang
Git (for submodules)

Build Steps

# Clone and build
git clone https://github.com/kryonlabs/kryon.git
cd kryon
git submodule update --init --recursive

# Build (recommended)
./scripts/build.sh

# Or manually
mkdir build && cd build
cmake ..
make -j$(nproc)

Running Examples

# List all examples
./scripts/run_examples.sh list

# Run a specific example
./scripts/run_example.sh hello-world raylib
./scripts/run_example.sh button raylib

# Run with debug output
./scripts/run_example.sh --debug button raylib

# Run all examples
./scripts/run_examples.sh raylib

Manual Usage

# Compile a .kry file to .krb binary
./build/bin/kryon compile examples/hello-world.kry -o examples/hello-world.krb

# Run the compiled binary
./build/bin/kryon run examples/hello-world.krb --renderer raylib

# Or compile and run in one step
./build/bin/kryon run examples/hello-world.kry --renderer raylib

Examples

See the examples/ directory for KRY application samples. Use the scripts to run them:

./scripts/run_examples.sh list    # List all examples
./scripts/run_example.sh hello-world raylib

Development

Running Tests

cd build
ctest --verbose

Build Scripts

./scripts/build.sh              # Release build
./scripts/build.sh --debug      # Debug build  
./scripts/build.sh --clean      # Clean build
