Calling a proc with importcpp and constructor pragma generate invalid C++ code

demotomohiro commented 1 year ago

Description

When importing C++ classes/structs and calling it's constructor to initialize module scope variable with other imported C++ classes/structs, Nim generates C++ code incorrectly. Example code testbugcpp.nim:

{.emit:"""
  struct Foo {
    int x;
  };

  struct Bar {
    Bar(Foo f): f(f) {}

    Foo f;
  };
""".}

type
  Foo {.importcpp.} = object
    x: cint

  Bar {.importcpp.} = object

proc constructBar(f: Foo): Bar {.importcpp: "Bar(@)", constructor.}

var b = constructBar(Foo(x: 1))

Compiled it with nim cpp testbugcpp.nim and got error from backend gcc.

Nim Version

git hash: da368885da8850c0c87e6b9dcff64393985aff27 active boot switches: -d:release

Current Output

/tmp/nimcache123/testbugcpp/debug/@mtestbugcpp.nim.cpp:51:36: error: ‘T1_’ was not declared in this scope
   51 | N_LIB_PRIVATE Bar b__testbugcpp_u6(T1_);

Expected Output

No compile error from backend C++ compiler.

Possible Solution

No response

Additional Information

In Nim generated C++ code, variable b__testbugcpp_u6 is declared outside of functions, and calls constructor with variable T1_. But T1_ is not declared there.

N_LIB_PRIVATE Bar b__testbugcpp_u6(T1_);

It is declared in NimMainModule function and it is not accessible from outside of functions.

N_LIB_PRIVATE N_NIMCALL(void, NimMainModule)(void) {
{
    Foo T1_{};
    nimfr_("testbugcpp", "/home/player/worktmpfs/testnim/testbugcpp.nim");
    T1_.x = ((int)1);
    nimlf_(21, "/home/player/worktmpfs/testnim/testbugcpp.nim");
    popFrame();
}
}

Nim should generate code like:

N_LIB_PRIVATE Bar b__testbugcpp_u6(Foo{(int)1});

Declaring the variable inside a procedure doesn't produce any error.

{.emit:"""
  struct Foo {
    int x;
  };

  struct Bar {
    Bar(Foo f): f(f) {}

    Foo f;
  };
""".}

type
  Foo {.importcpp.} = object
    x: cint

  Bar {.importcpp.} = object

proc constructBar(f: Foo): Bar {.importcpp: "Bar(@)", constructor.}

proc main =
  var b = constructBar(Foo(x: 1))

main()

!nim cpp --gc:arc

{.emit:"""
struct Foo {
  int x;
};
struct Bar {
  Bar(Foo f): f(f) {}
  Foo f;
};""".}

type
  Foo {.importcpp.} = object
    x: cint
  Bar {.importcpp.} = object

proc constructBar(f: Foo): Bar {.importcpp: "Bar(@)", constructor.}
var b = constructBar(Foo(x: 1))

either support default constructor so can separate the declaration and initialization, or treat the constructor arguments as global too.
