LibJuno

LibJuno

• LibJuno GitHub
• LibJuno is a lightweight C99 library designed specifically for embedded systems.
• LibJuno enables embedded systems developers to utilize dependency injection within C99 in a memory-safe manner
• LibJuno provides essential functionalities like memory management, data structures, string operations and more all without dynamic memory allocation!
• LibJuno optimizes for memory safety, determinism and efficiency in constrained environments.
• LibJuno is compiled without the standard library to maximize portability.

Using LibJuno

• By default, LibJuno will compile both a shared and static library

Documentation

Dependency Name	Rationale

Building and Testing

1. Generate build files:
   • cmake -B build .
2. Compile the project:
   • make -C build
3. Run unit-tests:
   • cmake -B build . -DJUNO_TESTS=ON
   • make -C build
   • cd build
   • ctest

CMake Build Option

• -DJUNO_TESTS=On (Default Off): Enable unit testing
• -DJUNO_COVERAGE=On (Default On): Compile Juno with code coverage
• -DJUNO_DOCS=On (Default Off): Enable doxygen docs
• -DJUNO_PIC=On (Default On): Compile Juno with Position Independent Code
• -DJUNO_SHARED=On (Default Off): Compile the juno shared library

Current Modules

• Memory Management: Provides block-based allocation, deallocation, and memory tracking.
• String Operations: Handles string initialization, manipulation, concatenation, and cleanup.

Future Modules

• Filesystem interactions
• Networking support
• Additional utility libraries for embedded applications

Inspiration for the Name

Juno is the name of my wonderful dog and she has brought me so much comfort and stability throughout the years. I wanted to honor her legacy by naming an open-source library after her.
