Using shell variables like $HOME in LazyVim’s nvim-lint configuration doesn’t work as expected—the string gets passed literally instead of being expanded. To use a custom markdownlint-cli2 config file with a machine-agnostic path, use Lua’s os.getenv() function:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12

local HOME = os.getenv("HOME")
return {
  "mfussenegger/nvim-lint",
  optional = true,
  opts = {
    linters = {
      ["markdownlint-cli2"] = {
        args = { "--config", HOME .. "/.markdownlint-cli2.yaml", "--" },
      },
    },
  },
}

Create your ~/.markdownlint-cli2.yaml configuration file with your preferred rules:

1
2

config:
  MD013: false
