• unwrapJsonishListIfPossible

  public static java.util.List<java.lang.String> unwrapJsonishListIfPossible(java.lang.String input)

  converts a comma separated list in a single string to a list of strings, doing what would be expected if given java or json style string as input, and falling back to returning the input.

  this method does not throw exceptions on invalid input, but just returns that input

  specifically, uses the following rules (executed once in sequence:

• 1) if of form [ X ] (in brackets after trim), then removes brackets and applies following rules to X (for any X including quoted or with commas)
• 2) if of form "X" (in double quotes after trim, where X contains no internal double quotes unless escaped with backslash) then returns list containing X unescaped (\x replaced by x)
• 3) if of form X or X, Y, ... (where X, Y, ... each satisfy the constraint given in 2, or have no double quotes or commas in them) then returns the concatenation of rule 2 applied to non-empty X, Y, ... (if you want an empty string in a list, you must double quote it)
• 4) for any other form X returns [ X ], including empty list for empty string
