eof

eof only succeeds (with null) at the end of the input.

Usage

const Parser = sequence(
  string('<start>'),
  string('<body>'),
  string('<end>'),
  eof()
)

Success

run(Parser).with(`<start><body><end>`)

{
  isOk: true,
  start: 0,
  end: 18,
  pos: 18,
  value: [ '<start>', '<body>', '<end>', null ]
}

Failure

run(Parser).with(`<start><body><end>\n`)

{
  isOk: false,
  start: 18,
  end: 18,
  pos: 18,
  expected: 'end of input'
}
