wrapper Parser instance specifying the completion tag
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).
the JValue for completion tag meta-data (to be used e.g. to specify the visual style for a completion tag in the menu)
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.
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. This allows for more flexibility when defining the grammar: various parsers can define the global completion meta-data with an additive effect.

p <~ q succeeds if p succeeds and q succeeds on the input
left over by p.

<~ has lower operator precedence than ~ or ~>.
A parser combinator for non-back-tracking sequential composition which only keeps the left result.
A parser combinator for non-back-tracking sequential composition which only keeps the left result.
p <~! q succeeds if p succeds and q succeds on the input left over by p.
In case of failure, no back-tracking is performed (in an earlier parser produced by the | combinator).
a parser that will be executed after p (this parser) succeeds -- evaluated at most once, and only when necessary
a Parser that -- on success -- reutrns the result of p.
The resulting parser fails if either p or q fails, this failure is fatal.

A parser combinator for partial function application.
A parser combinator for partial function application.
p ^? f 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.
a partial function that will be applied to this parser's result
(see mapPartial in ParseResult).
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.
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.
a partial function that will be applied to this parser's result
(see mapPartial in ParseResult).
a function that takes the same argument as f and produces an error message
to explain why f wasn't applicable
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.
A parser combinator for function application.
A parser combinator for function application.
p ^^ f succeeds if p succeeds; it returns f applied to the result of p.
a function that will be applied to this parser's result (see map in ParseResult).
a parser that has the same behaviour as the current parser, but whose result is
transformed by f.
A parser combinator that changes a successful result into the specified value.
A parser combinator that changes a successful result into the specified value.
p ^^^ v succeeds if p succeeds; discards its result, and returns v instead.
The new result for the parser, evaluated at most once (if p succeeds), not evaluated at all if p fails.
a parser that has the same behaviour as the current parser, but whose successful result is v
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.
a function that, given the result from this parser, returns the second parser to be applied
a parser that succeeds if this parser succeeds (with result x)
and if then fq(x) succeeds

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!")
The message that will replace the default failure message.
A parser with the same properties and different failure message.

A parser combinator for alternative composition.
A parser combinator for alternative composition.
