          name = "node",
          cmd = "node",
          check = function()
            return vim.fn.executable("node") == 1 and vim.fn.system("node -v"):match("v16") ~= nil
          end,
          install = {
            linux = { "sudo apt install nodejs" },
            darwin = { "brew install node" },
            windows = { "choco install nodejs" },
          },

      },
      auto_check = true,
      open_float = true,
    })
  end

Usage

• Run :DepsCheck to check dependencies.
• If missing dependencies are found:
  • A floating window will open.
  • Each missing dependency is listed with its install commands.
  • Move the cursor to an install command and press <CR> to open a bottom vsplit terminal and run it.
  • Press q to close the floating window.

Configuration

Options passed to setup:

{
  list = { ... },  -- table of dependencies
  auto_check = false, -- run automatically at startup
  open_float = true,  -- open floating window if missing deps
}

Dependency spec fields

• name: Display name.
• cmd: The executable name to check (optional if using check).
• check: A custom Lua function that takes no parameters and returns true if installed.
• install: A table of possible install commands by platform (keys: linux, darwin, windows).

Example

{
  name = "python3",
  cmd = "python3",
  install = {
    linux = { "sudo apt install python3" },
    darwin = { "brew install python3" },
    windows = { "choco install python3" },
  }
}
