Functions

func CutDiffAroundLine

func CutDiffAroundLine(originalDiff io.Reader, line int64, old bool, numbersOfLine int) string

CutDiffAroundLine cuts a diff of a file in way that only the given line + numberOfLine above it will be shown it also recalculates hunks and adds the appropriate headers to the new diff. Warning: Only one-file diffs are allowed.

Example
const diff = `diff --git a/README.md b/README.md
