Greetings! This is the repository for our Smart Symbolic Graphing Calculator. Written in C/C++, this project utilizes LVGL and Giac to create a free and open source and extensible symbolic calculator that is able to used in both testing environments and general calculation applications. Websocket communication is done using the easywsclient library. JSON manipulation is made possible by the JSON for Modern C++ and json-schema-validator libraries.

Some of the algorithmic implementations, such as plotting and optimal tick generation, were gathered and translated from the Julia Programming Language into C++.

The currently reccommended method of building this project is using CMake in a POSIX-compliant environment. Windows is technically supported, however, many features may not work or are broken.

Current default build flags are as follows:

• -DLINUX_ENABLE=ON
• -DGIAC_ENABLE=ON
• -DPI_ENABLE=OFF
• -DWINDOWS_ENABLE=OFF

The following is a quickstart on how to clone and build this project on arch linux with proper vscode intellisense support:

sudo pacman -S base-devel giac sdl2 cmake
git clone --recursive https://github.com/GKJose/Smart_Symbolic_Graphing_Calculator.git
cd Smart_Symbolic_Graphing_Calculator
cmake -DGIAC_ENABLE=ON .
cmake --build .

The following command below is an example on how to clone and build this project on the raspberry pi:

sudo apt install -y build-essential libgiac-dev libmpfr-dev libgmp3-dev python3-smbus i2c-tools cmake nmap
git clone --recursive https://github.com/GKJose/Smart_Symbolic_Graphing_Calculator.git
cd Smart_Symbolic_Graphing_Calculator
cmake -DLINUX_ENABLE=OFF -DPI_ENABLE=ON -DGIAC_ENABLE=ON .
make all -j

The binary file named SSGC will appear in the build/out directory.

To run the binary file, simply write ./build/out/SSGC.

To have proper intellisense support while developing this project, ensure that the Cmake Tools extension is installed, and that the project is configured.

To configure the project, press Ctrl + Shift + P, and search for the Cmake: Configure option. The project should correctly automatically configure itself. In the event that the log output changes, i.e. Enabling Giac Linkage... no longer appeared in stdout after configuring, run cmake -DGIAC_ENABLE=ON . to fix any possible linkage issues.

If for any reason CMake is not available on your system. A portable python 3.10.2 build system is also included with the project named cinit.

To initialize the project run ./cinit.py init first (if not done, the project will fail to build). To build the project, run ./cinit.py make -j. The resulting binary should be present in the build/out directory.

Please note that the cinit.py build system may not be updated to work with the latest version of the project. It is highly recommended to build this project using CMake.
