An operator to specify the completion tag meta-data of a parser in JSON format (empty by default).
An operator to specify the completion tag meta-data of a parser in JSON format (empty by default). JSON meta-data is automatically merged when combining two equivalent tags (i.e. bearing the same label, but with a different payload). This allows for more flexibility when defining the grammar: various parsers can return the same completion tags with an additive effect on the meta-data (and the entries).

returns
wrapper Parser instance specifying the completion tag meta-data

An operator to specify the meta-data for the whole set of completions (empty by default) Note that if the meta-data is encoded in JSON, it is automatically merged when combining multiple completion sets.

f
a partial function that will be applied to this parser's result (see mapPartial in ParseResult).
returns
a parser that succeeds if the current parser succeeds and f is applicable to the result. If so, the result will be transformed by f.
abstract def ^?[U](f: PartialFunction[T, U], error: (T) => String): P[U]
A parser combinator for partial function application.
A parser combinator for partial function application.
p ^? (f, error) succeeds if p succeeds AND f is defined at the result of p; in that case, it returns f applied to the result of p. If f is not applicable, error(the result of p) should explain why.
f
a partial function that will be applied to this parser's result (see mapPartial in ParseResult).
error
a function that takes the same argument as f and produces an error message to explain why f wasn't applicable
returns
a parser that succeeds if the current parser succeeds and f is applicable to the result. If so, the result will be transformed by f.

abstract def into[U](fq: (T) => P[U]): P[U]
A parser combinator that parameterizes a subsequent parser with the result of this one.
A parser combinator that parameterizes a subsequent parser with the result of this one.
Use this combinator when a parser depends on the result of a previous parser. p should be a function that takes the result from the first parser and returns the second parser.
p into fq (with fq typically {x => q}) first applies p, and then, if p successfully returned result r, applies fq(r) to the rest of the input.
From: G. Hutton. Higher-order functions for parsing. J. Funct. Program., 2(3):323--343, 1992.
fq
a function that, given the result from this parser, returns the second parser to be applied
returns
a parser that succeeds if this parser succeeds (with result x) and if then fq(x) succeeds
Example:
1. def perlRE = "m" ~> (".".r into (separator => """[^%s]*""".format(separator).r <~ separator))

n
the limit
returns
wrapper Parser instance limiting the number of completions
abstract def withErrorMessage(msg: String): P[T]
Changes the failure message produced by a parser.
Changes the failure message produced by a parser.
This doesn't change the behavior of a parser on neither success nor error, just on failure. The semantics are slightly different than those obtained by doing | failure(msg), in that the message produced by this method will always
replace the message produced, which is not guaranteed by that idiom.
For example, parser p below will always produce the designated failure message, while q will not produce
it if sign is parsed but number is not.
```
def p = sign.? ~ number withFailureMessage  "Number expected!"
def q = sign.? ~ number | failure("Number expected!")
```
msg
The message that will replace the default failure message.
returns
A parser with the same properties and different failure message.
abstract def withFailureMessage(msg: String): P[T]
Changes the failure message produced by a parser.
Changes the failure message produced by a parser.
This doesn't change the behavior of a parser on neither success nor error, just on failure. The semantics are slightly different than those obtained by doing | failure(msg), in that the message produced by this method will always replace the message produced, which is not guaranteed by that idiom.
For example, parser p below will always produce the designated failure message, while q will not produce it if sign is parsed but number is not.
```
   def p = sign.? ~ number withFailureMessage  "Number expected!"
def q = sign.? ~ number | failure("Number expected!")
```
msg
The message that will replace the default failure message.
returns
A parser with the same properties and different failure message.

abstract def |[U >: T](q: => P[U]): P[U]
A parser combinator for alternative composition.
A parser combinator for alternative composition.

q
a parser that will be executed if p (this parser) fails (and allows back-tracking)
returns
a Parser that returns the result of the first parser to succeed (out of p and q) The resulting parser succeeds if (and only if)

abstract def |||[U >: T](q: => P[U]): P[U]
A parser combinator for alternative with longest match composition.
