how to delete blank line which is inserted by vscode auto-formating function?-CodePudding

My elixir code is as follows, the editor is vscode. When auto formating by shortcut key of alt-shift-f, a blank line will appear before the following Logger.debug line. It will reappear even if it is deleted. Why it need a blank line here. Is it possible to not add the blank line?

  test "calculate_line_point_test 1/4,1 point" do
    whole_angle = :math.pi() / 4
    start_angle = :math.atan(1 / 4)
    n = 4
    k = 1
    result = InventoryMap.calculate_line_point(whole_angle, start_angle, n, k, 3, [])
    # {2,10}
    assert result == [
             {2, 0.21866894587394198},
             {3, 0.17985349979247828},
             # [{2, 0.21866894587394198}]
             {4, 0.1418970546041638}
           ]
             #<---- blank line appear here
    Logger.debug("get_angle: #{inspect(result)}")
  end

CodePudding user response：

This behaviour has nothing to do with a particular editor, they all delegate to the language server and mix format which is exposed by elixir itself (dig around Code.Fragment.)

Formatter is the tool provided by elixir core team to standardize the code L&F. While it’s still possible to implement custom formatters and plug them into the existing project, I would strongly discourage doing that.

mix format is the standard member of the CI pipeline and everyone expects it to perform in a common way (e. g. as after the standard mix format without any custom formatters applied.) Just accept it :)
