How would I parse an angular serve to notify me when its actually started?

[Ajaymamtora]

I have the following

return {
  name = "ng serve",
  builder = function()
    return {
      cmd = { "ng", "serve" },
      components = {
        {
          "on_output_parse",
          parser = require("overseer.parser.angular"),
        },
      },
    }
  end,
}

...
return {
  "on_output_parse",
  parser = {
    -- Set up the initial state
    { "set_defaults", values = { status = "running" } },
    {
      -- Use a loop to continuously parse the output
      "loop",
      {
        "sequence",
        -- Check for the success message
        {
          "extract",
          { consume = true },
          "^Application bundle generation complete%.$",
        },
        -- If found, update the status, notify, and stop the parser
        {
          "set_defaults",
          values = { status = "success" },
        },
        {
          "dispatch",
          function(_, _, line)
            vim.schedule(function()
              vim.notify("Angular serve started successfully: " .. line, vim.log.levels.INFO)
            end)
            return "stop"
          end
        },
      },
    },
  },
}

I'm fully stuck - I just want to run a callback when the string "Application bundle generation complete" is outputted

While this can be done with the existing components and parser system, it's not really built for it and will feel pretty clunky. I would suggest creating your own custom component that uses on_output_lines to watch for this line and then you can do whatever you want there.
