libtlvcpp is a modern C++ ASN.1 tree manipulating & encoding/decoding library with a focus on a clean interface and automatic memory management. The library consists of three main components: tree_node, tlv, and tlv_tree_node. The tree_node represents a generic tree structure, tlv represents a TLV element, and tlv_tree_node is a specialized tree node for TLV elements.

• Clean Interface: Provides a simple and intuitive interface for working with TLV data structures.
• Automatic Memory Management: Utilizes modern C++ features to handle memory management automatically.
• Flexible Tree Structure: The tree_node class allows you to create a flexible tree structure for organizing TLV elements.
• Works on: Windows, Linux, macOS, ESP-IDF, and Webassembly using Emscripten.

#include "tlv_tree.h"

// Create a TLV tree node
tlvcpp::tlv_tree_node root;

// Add TLV elements to the tree
root.add_child(1, "Value1");
auto& childNode = root.add_child(2, "Value2");

// Add child elements to a node
childNode.add_child(3, "Value3");

// Dump the tree structure
root.dump();

// Serialize the TLV tree to a vector
std::vector<uint8_t> buffer;
root.serialize(buffer);

// Deserialize the TLV tree from a vector
tlvcpp::tlv_tree_node newRoot;
newRoot.deserialize(buffer);

// Find a TLV element by tag
tlvcpp::tlv* foundElement = root.find(2);

// Find an immediate child TLV element by tag
tlvcpp::tlv* foundImmediateElement = root.find_immediate(2);

libtlvcpp uses CMake for its build process. Follow these steps to build the library:

1. Create a build directory:

   mkdir build
   cd build

2. Generate build files with CMake:

   cmake ..

3. Build the library:

   cmake --build .
