When the constructor has parameters, it also generates a default constructor. One can avoid this behaviour by using `noDecl` in a default constructor. Like `virtual`, `constructor` also supports a syntax that allows to express C++ constraints. diff --git a/tests/cpp/tconstructor.nim b/tests/cpp/tconstructor.nim index 8c5d4dca2..ac73b78e6 100644 --- a/tests/cpp/tconstructor.nim +++ b/tests/cpp/tconstructor.nim @@ -16,6 +16,7 @@ ___ 777 10 123 +() ''' """ @@ -106,4 +107,12 @@ proc init = n.x = 123 echo n.x -init() \ No newline at end of file +init() + +#tests that the ctor is not declared with nodecl. +#nodelc also prevents the creation of a default one when another is created. +type Foo {.exportc.} = object + +proc makeFoo(): Foo {.used, constructor, nodecl.} = discard + +echo $Foo() \ No newline at end of file |
