APIs

• generate_operate_list__single(prev: string, curr: string): number[]
  • diffs two string, comparing character by character.
  • return a list of number.
    • 1: INSERT - insert a characters into prev
    • 2: DELETE - delete a characters from prev
    • 3: MOVE - the same characters as in prev, but the position(index) are not guaranteed to be the same

• generate_operate_list__single(prev: string, curr: string): {type: number, label: ('INSERT' | 'DELETE' | 'MOVE'), char: string}[]
  • diffs two string, comparing character by character.
  • returns the operations performed in sequence, one for each operation.

• generate_operate_list__group(prev: string, curr: string): {type: number, label: ('INSERT' | 'DELETE' | 'MOVE'), char: string}[]
  • diffs two string, comparing character by character.
  • returns operations performed sequentially, consecutive identical operations are merged.

• generate_operate_list__overview(prev: string, curr: string): [str_result: string, str_label: string]
  • diffs two string, comparing character by character.
  • return a tuple with string in [0] and label(+/-/) in [1]
