LunarVim configurations.

Notice: This repository is no longer maintained.

We have transitioned to a new generation of Java development environment configurations. The new setup, called JVIM, is not based on Lunarvim but instead on a Neovim itself. All Java-related features are present and actively maintained.

Please visit the new repository: JVIM

Thank you for your understanding and continued support.

Plugins and Tools

Copilot

Copilot is a plugin for LunarVim that uses OpenAI's Codex to provide code completions and suggestions. Completions (alt+l) are available in insert mode and suggestions are available in normal mode in which-key menu.

To use it, follow these steps:

• Run :Copilot setup and enter your Copilot account credentials.
• Enable the plugin by running :Copilot enable

Open AI. Chat GPT-4

Chat GPT is a plugin for LunarVim that uses OpenAI's GPT-4 to provide code completions and suggestions.

To use it you need to have an OpenAI API key. Set the OPENAI_API_KEY environment variable in your shell and run :ChatGPT enable in LunarVim.

echo "export OPENAI_API_KEY=YOUR_PERSONAL_OPENAI_API_KEY" >> $HOME/.zshrc

All features are available in the which-key menu.

Docker Container

You can use the Docker container configured in a separate project in a few simple steps.

• Pull the image

docker pull israiloff/lvim:latest

• Run the container with only necessary ports

docker run -it -d -p 33235:33235 --name lvim israiloff/lvim:latest

• Run the container with additional ports and access to docker itself

docker run -it -d -p 33235:33235 -p 8090-8099:8090-8099 -v /var/run/docker.sock:/var/run/docker.sock --name lvim israiloff/lvim:latest

Port 33235 is used for the markdown preview server. Ports 8090-8099 are additional ports for debugging and testing.

• Enter the container

docker exec -it lvim /bin/zsh
