Function takeWhile

takeWhile<TToken, TOptions, TValue>(p: Parser<TToken, TOptions, TValue>, test: ((value: TValue, n: number, data: Data<TToken, TOptions>, i: number, j: number) => boolean)): Matcher<TToken, TOptions, TValue[]>
Make a Matcher that returns all (0 or more) sequential matches of the same given parser while the test function equates to true.

Use many if there is no stop condition.

Use takeWhileP if the stop condition is expressed as a parser.
Type Parameters
- TToken
- TOptions
- TValue
Parameters
- p: Parser<TToken, TOptions, TValue>
  
  A parser.
- test: ((value: TValue, n: number, data: Data<TToken, TOptions>, i: number, j: number) => boolean)
  
  Matched results are accumulated while the result of this function is true.
  - - (value: TValue, n: number, data: Data<TToken, TOptions>, i: number, j: number): boolean
    - Parameters
      
      value: TValue
      
      Current value matched by the parser.
      
      n: number
      
      Number of matches so far (including the current value).
      
      data: Data<TToken, TOptions>
      
      Data object (tokens and options).
      
      i: number
      
      Parser position in the tokens array (before the current value matched).
      
      j: number
      
      Parser position in the tokens array (after the current value matched).
      
      Returns boolean
Returns Matcher<TToken, TOptions, TValue[]>
