Run with Docker

You can run this project with Docker. This is the easiest way to get started.

Steps

1. Clone this repository:

git clone https://github.com/jschang19/chatcpp.git
cd chatcpp

2. Get your OpenAI token from here and set it as the ENV in the Dockerfile file ( or pass it as an argument to docker run command later).

3. Install Docker, then run the following commands:

docker build -t chatcpp . # this will take a while
docker run -it --env=OPENAI_API_KEY=<YOUR_OPENAI_API_KEY> chatcpp:latest # run with interactive mode

Development

To develop this project, you need to install CMake and Vcpkg first.

1. Export your OpenAI token to environment variable

export OPENAI_API_KEY=<YOUR_OPENAI_API_KEY>

2. Install dependencies with VCPKG

git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg

# Windows
./bootstrap-vcpkg.bat
# Mac/Linux
./bootstrap-vcpkg.sh

./vcpkg install nlohmann-json
./vcpkg install cpr
./vcpkg integrate install

3. Build the project with CMake

rm -rf build
mkdir build
cmake -B build/ -S . -DCMAKE_TOOLCHAIN_FILE=/Users/liaohuizhong/Library/CloudStorage/OneDrive-個人/文件/大學/大學課業/大一上/程式設計/ntu-im-final-project/vcpkg/scripts/buildsystems/vcpkg.cmake
cd build
cmake --build .

xcvv/c/ 4. Run the project

./ChatBot

5. Everytime you make changes to the code, you need to run cmake --build . in the build folder again to rebuild the project.

cd build
cmake --build .

Update Vcpkg

If getting error when running cmake --build . in the build folder, you need to update the vcpkg:

cd ~/vcpkg # or where you install vcpkg
git pull
rm -rf installed
./vcpkg install nlohmann-json
./vcpkg install cpr

Then run the cmake command again. You need to rm -rf build/ and build again.

Reminder

• This project is still under developmentm and ChatGPT might return invalid json sometimes.
• This project uses gpt3.5 model with json formatted response. Check the official API for more details.
• The reply generation is not very stable. You may see unrelevant options sometimes.
