X::Eval::NoSuchLang Reference

Error due to specifying an unknown language for EVAL

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 lang #

method lang()

Returns the language that EVAL did not know how to handle.

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::Eval::NoSuchLang is Exception { }

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

EVAL 'boo', lang => "bar";
CATCH { default { put .^name, ': ', .Str } };
# OUTPUT: «X::Eval::NoSuchLang: No compiler available for language 'bar'␤»
Output
X::Eval::NoSuchLang: No compiler available for language 'bar'

Documentation, Rakudo and Raku++ all agree.
