TODO

Add git support inside container
Allow container to start debugger inside another container
Allow container to start other containers in the system

This repo describes the process of setting up nvim inside a docker invironment and allowing it to have both lsp and debugging capabilities

Requirements

Your own Astronvim user config

Instructions

Place docker file inside desired python repository
Modify the docker file to be as close to your project setup as possible
Update the links to configs in docker file to point to your own config repo
Start your environtment
Ssh into your environtment and install gdb and debugpy
Before running the debugger, we need to add the following to the docker compose service that we want to debug:
```
cap_add: 
    - SYS_PTRACE
```

Attach debugpy to the correct process with this command:

 python -m debugpy --listen 0.0.0.0:5678 --pid 19 --configure-subProcess False

Build the docker environment

cd ~/your_project_path
docker build -f DockerfileNvimAstro -t django_dev_env .

Run you docker environment

docker run -it --network=host -e DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix -v ~/path_to_your_project:/home/dev/you_project_name django_dev_env:latest

Note: if you want to iterate over your astronvim user config without having to rerun the whole docker file everytime, you can run it with this command to partially invalidate the cache

docker build --build-arg CACHE_DATE=$(date) -f DockerfileNvimAstro -t django_dev_env .

For the debugging to work in nvim, the astronvim user config would need to have a file called setup_handlers.lua in the path user/mason-nvim-dap/

The file should contain the follow lua code:

local debug_port = 5678
local host = "0.0.0.0"

return {
  python = function(source_name)
    local dap = require("dap")
    dap.adapters.python = {
      type = "server",
      host = host,
      port = tonumber(debug_port),
    }

    dap.configurations.python = {
      {
        type = "python",
        request = "attach",
        connect = {
          port = tonumber(debug_port),
          host = host,
        },
        mode = "remote",
        name = "Remote Attached Debugger",
        cwd = vim.fn.getcwd(),
        pathMappings = {
            {
              localRoot = vim.fn.getcwd(), -- Wherever your Python code lives locally.
              remoteRoot = "/app", -- Wherever your Python code lives in the container.
            };
        };
      },
    }
  end,
}

Run xhost local:root on host to share clippboard
