Functions

func DoWhitediff

func DoWhitediff(a io.Reader, b io.Reader) (float64, error)

DoWhitediff performs a whitediff comparision on the two input readers. It returns:

• "1.0" if the streams match,
• "0.0" if not,

and any errors encountered while trying to exhaust the readers.

Types

type Ellen

type Ellen struct {
	// contains filtered or unexported fields
}

Ellen (an abbreviation of checker in hungarian) checker is used by mester, bíró systems.

Arguments of the checker are:

1. Absolute path to testdata
2. Absolute path to output data
3. Index of testcase to check

Testcases are named in.{x} and out.{x} where x is an 1 indexed integer.

It produces its output to stdout in the following format:

{test_index};{subtest_number};{point_multiplier};{verdict_message}

• test_index: the index received via the argument
• subtest_number: refer to the github.com/mraron/njudge/pkg/problems/config/feladat_txt config's docs
• point_multiplier: 0 or 1, depending on the correctness
• verdict_message: A message displayed to the user (it must not contain ";" or ":" characters)

If there are multiple subtests the same format should be used delimited by a single ":"

func NewEllen

func NewEllen(ellenPath, testcaseDir string, testCount int, points []int) Ellen

type Noop

type Noop struct{}

Noop doesn't perform any checking

func (Noop) Check
