#criterion_cell(label, stats, color) ⇒ Object

A "lines" cell always, "branches" and "methods" cells only when the touched lines actually carried one: a hollow 0/0 cell is noise.

#gate(rows, minimum) ⇒ Object

No --minimum is report-only. With one, every measured criterion must clear the floor, and short? never fails an unmeasured one.

#measured?(stats) ⇒ Boolean

Branch and method stats are nil when the report never measured them, and 0/0 when the change touched none.

Returns:

#ranges(numbers, separator = ", ") ⇒ Object

Collapses a sorted line list into ranges: [41, 42, 43, 47] -> "41-43, 47". The show subcommand borrows this with a bare-comma separator for its greppable path:40,52-58,71 form.

    out << separator unless out.empty?
    out << (run.one? ? only(run) : span(run))
  end
end

#short?(stats, minimum) ⇒ Boolean

Cross-multiplied rather than compared as percentages so neither rounding nor float division can shift the verdict at the boundary: reading the displayed pct would round a 19_999/20_000 patch up to 100 and pass it against --minimum 100, while dividing makes 23/40 compute as 57.4999... and fail an exactly-57.5% patch. The minimum becomes an exact Rational from its own text, and covered * 100 is an integer, so the comparison is exact. A criterion with nothing relevant never falls short.

Returns:

  • (Boolean)
