X::Str::Match::x Reference

Invalid argument type for :x argument to Str matching methods

What it is #

Routines #

Signatures are reproduced from the documentation, including their declared return types. A routine listed here is part of the type's published interface; whether Raku++ implements it is a separate question, answered by the examples below.

method source #

method got(--> Str:D)

Returns Str:D.

Returns the type of the invalid argument.

Examples, run three ways #

Every example below comes from the official documentation, together with the output that documentation asserts. Each was then executed by Rakudo and by Raku++ when this page was built. Where the three agree, one result is shown; where they do not, all three are — because which of them is wrong is exactly the information worth having.

class X::Str::Match::x is Exception { }

Not executed: the documentation states no expected output for this example.

say "foobar".match("o",:x<hello>);
CATCH { default { put .^name, ': ', .Str } };
# OUTPUT: «X::Str::Match::x: in Str.match, got invalid value of type Str for :x, must be Int or Range␤»
Output
X::Str::Match::x: in Str.match, got invalid value of type Str for :x, must be Int or Range

Documentation, Rakudo and Raku++ all agree.
