  | {pos_integer(), non_neg_integer(), pos_integer(), non_neg_integer()}

Where in a file the diagnostic applies. Can be either a line number, a range specified as {start_line, start_col, end_line, end_col}, or nil if unknown.

Line numbers are one-based, and column numbers in a range are zero-based and refer to the cursor position at the start of the character at that index. For example, to indicate that a diagnostic applies to the first n characters of the first line, the range would be {1, 0, 1, n}.

Specs

severity() :: :error | :warning | :information | :hint

Severity of a diagnostic:

  • :error - An issue that caused compilation to fail

  • :warning - An issue that did not cause failure but suggests the programmer may have made a mistake

  • :hint - A suggestion for style or good practices that is not as severe as a warning

  • :information - Any other information relevant to compilation that does not fit into the above categories
