This combinator parses a p
enclosed within angle brackets.
This combinator parses a p
enclosed within angle brackets.
First parse an open bracket, any whitespace, then parse, p
, producing x
. Finally, parse a closing bracket and any whitespace. If all three parts succeeded, then return x
. If any of them failed, this combinator fails.
Value parameters
- p
-
the parser to parse between parentheses.
Attributes
- Returns
-
a parser that reads an open bracket, then
p
, then a closing bracket and returns the result ofp
. - Since

- Example
-
scala> ... scala> val p = lexer.nonlexeme.enclosing.brackets(int) scala> p.parse("< 5>") val res0 = Success(5) scala> p.parse("<5") val res1 = Failure(...) scala> p.parse("5>") val res2 = Failure(...)
