generic-diff-context v0.2.5

generic-diff-context

Filter reports from generic-diff or compatible modules to give changes with optional context.

API

genDiffCtx(report, opts)

• report: the one generated by generic-diff or a compatible module.
• opts: config object
  • mergePairs: (bool) (default: false) Whether pairs of deletion and addition shall be merged.
  • unified: (number | object | bool) (default: false) With number(s) given, return a unified diff, i.e. array of changes, each change being an array of lines changed. The number sets how much context = how many unchanged items to include on both sides of the change(s). Give an object with number properties before and after to select them separately. You can also use the 0 property instead of before, and 1, instead of after, so an array of two numbers will work.
  • finalLf: (bool) (default: false; default in unified mode: true) Whether to report the trailing newline as GNU diff does: If the last line has a newline at its end, omit it, otherwise add a message that there was no newline at end of input.

genDiffCtx(a, b, opts)

Like above, but generate the report by generic-diffing a and b.
