Overview

In this article, we will explore the process of integrating Lightning Core BOLT11 invoice parsing into our existing invoice_deserialization target. This integration will enable us to leverage the power of Lightning Core's BOLT11 protocol for parsing invoices, enhancing the overall functionality and efficiency of our system.

Technical Challenges

Integrating Lightning Core BOLT11 invoice parsing into our existing invoice_deserialization target poses several technical challenges. These challenges include:

Complex Architecture: Lightning Core has a complex architecture with numerous interdependent modules. This complexity makes it difficult to identify and extract the relevant components required for BOLT11 invoice parsing.
Extensive Makefile Build System: The project uses an extensive Makefile build system, which can be challenging to navigate and modify. This complexity can lead to errors and inconsistencies in the build process.
Careful Extraction of Relevant Components: Integration will require careful extraction of the relevant components from Lightning Core. This process involves identifying the specific BOLT11 invoice parsing modules, creating a new wrapper file, and copying the required dependencies and source files.

Proposed Solution

To overcome the technical challenges and successfully integrate Lightning Core BOLT11 invoice parsing into our existing invoice_deserialization target, we propose the following solution:

Step 1: Identify Specific BOLT11 Invoice Parsing Modules in Lightning Core

The first step in integrating Lightning Core BOLT11 invoice parsing is to identify the specific modules responsible for parsing BOLT11 invoices. This involves analyzing the Lightning Core codebase and identifying the relevant components.

Step 2: Create a New Wrapper File Exposing Only the Necessary Decode Function

Once the relevant modules are identified, we will create a new wrapper file that exposes only the necessary decode function from Lightning Core. This wrapper file will serve as an interface between our existing code and the Lightning Core BOLT11 parsing functionality.

Step 3: Copy Required Dependencies and Source Files to Our Project

The next step is to copy the required dependencies and source files from Lightning Core to our project. This involves carefully extracting the necessary files and ensuring that they are properly configured for our project.

Step 4: Create a Simplified Makefile for Compiling Necessary Lightning Core Components

To compile the necessary Lightning Core components, we will create a simplified Makefile that only compiles the required components and links them directly with our C++ code. This will leverage C/C++ interoperability through extern "C" declarations.

Implementation Details

To implement the proposed solution, we will follow these steps:

Step 1: Identify Specific BOLT11 Invoice Parsing Modules in Lightning Core

Analyze the Lightning Core codebase to identify the specific modules responsible for parsing BOLT11 invoices.
Use tools such as grep and sed to search for relevant code patterns and identify the necessary modules.

Step 2: Create a New Wrapper File Exposing Only the Necessary Decode Function

Create a new file (e.g., bolt11_parser.h) that exposes only the necessary decode function from Lightning Core.
Use C/C++ interoperability through extern "C" declarations to ensure that the wrapper file can be used with our existing C++ code.

Step 3: Copy Required Dependencies and Source Files to Our Project

Copy the required dependencies and source files from Lightning Core to our project.
Ensure that the copied files are properly configured for our project and can be compiled and linked correctly.

Step 4: Create a Simplified Makefile for Compiling Necessary Lightning Core Components

Create a new Makefile (e.g., bolt11_parser.mk) that only compiles the necessary Lightning Core components.
Use C/C++ interoperability through extern "C" declarations to ensure that the compiled components can be linked with our existing C++ code.

Example Code

Here is an example of how the wrapper file (bolt11_parser.h) might look:

#ifndef BOLT11_PARSER_H
#define BOLT11_PARSER_H

extern "C" {
    int decode_bolt11_invoice(const char* invoice);
}

#endif  // BOLT11_PARSER_H

And here is an example of how the simplified Makefile (bolt11_parser.mk) might look:

# Define the necessary dependencies and source files
BOLT11_PARSER_SRCS = bolt11_parser.c
BOLT11_PARSER_DEPS = lightning-core/liblightning.a

# Define the compilation flags
CFLAGS = -Wall -Wextra -O2

# Define the linking flags
LDFLAGS = -Llightning-core/lib -llightning

# Define the target
TARGET = bolt11_parser

# Define the build rule
$(TARGET): $(BOLT11_PARSER_SRCS)
    $(CXX) $(CFLAGS) $(BOLT11_PARSER_SRCS) -o $(TARGET) $(LDFLAGS)
