      "BufEnter *.spec.[tj]s"
    },
    config = true
  }

Configuration

See full configuration options in the docs.
Initialize using setup with the default options (you don't need to supply these values):

require("clownshow").setup({
  mode = "inline", -- "inline" or "above"
  show_icon = true,
  show_text = false,
  project_root = function()
    local cmd_path = vim.fn.findfile("node_modules/.bin/jest", ".;")
    return vim.fn.fnamemodify(cmd_path, ':p:h:h:h')
  end,
  jest_command = function()
    local cmd_path = vim.fn.findfile("node_modules/.bin/jest", ".;")
    return vim.fn.fnamemodify(cmd_path, ':p')
  end,
  create_output_win = function()
    local win = vim.api.nvim_get_current_win()
    vim.cmd("vsplit")
    local output_win = vim.api.nvim_get_current_win()
    vim.wo[output_win].number = false
    vim.wo[output_win].cursorline = false
    vim.wo[output_win].relativenumber = false
    vim.wo[output_win].signcolumn = "yes:1" -- for some padding
    vim.fn.win_gotoid(win)
    return output_win
  end,
  passed = {
    icon = "✓",
    text = "Passed",
    hl_group = "LspDiagnosticsInformation"
  },
  failed = {
    icon = "✗",
    text = "Failed",
    hl_group = "LspDiagnosticsError"
  },
  skipped = {
    icon = "⭘",
    text = "Skipped",
    hl_group = "LspDiagnosticsWarning"
  },
  loading = {
    icon = "●",
    text = "Loading...",
    hl_group = "LspDiagnosticsWarning"
  }
})

Making configuration changes after initial setup using set_options:

require("clownshow").set_options({ ... })
