diff-sequences

Upstream: https://github.com/facebook/jest/tree/v27.4.7/packages/diff-sequences

Compare items in two sequences to find a longest common subsequence.

:pencil2: Notes

  • :x: Property tests and performance tests from upstream are not included.
  • :warning: Lua does not allow indexing into strings, the consumer is expected to handle the input types in isCommon and foundSubsequence.
    • A stringToArray function is implemented to convert input strings to arrays for tests.
    • Substring tests are done using arrays of characters instead. The substring comparison methods are omitted.
  • Lua is 1 indexed so array indices are replaced with index + 1.
  • Uses of NOT_YET_SET are replaced with just a 0 since this is a JS-specific workaround.
  • Lua treats 0 as a true value so nChange || baDeltaLength needs to be written as nChange ~= 0 and nChange or baDeltaLength.
