MIRROR_CLASS and visibility
La MACRO MIRROR_CLASS comporte "public:" qui a pour effet de se propager (une fois la macro passée) aux champs suivants.
N'y a-t-il pas une autre possibilité qui soit tout aussi transparente mais qui ne déborde pas ?
Exemple: drawFileInfo était publique, mais si je ne connais pas mirror et que je lis ce code, je la considère privée.
Bon, après j'aurais pu mieux la placer c'est une erreur de ma part...
MIRROR_CLASS_DEFINITION fail at runtime
Under linux (Ubuntu 20, clang 10) I have a problem with MIRROR_CLASS_DEFINITION.
I tried it with a single class, I'm unable to run the program, I got stuck inside the expression of an assert (checking if TypeId exists or not in a map). The runtime error occurs in the std, a division by zero:
everything starts here in mirror:
With the value:
For information, the map m_typeById is empty. Any idea ?
PS: I changed my keyboard, I prefer to use English because accents are missing on this one.
Compilation de mirror échoue sur master
OS: Ubuntu 20.04, 64bits
Je viens d'essayer de compiler mirror à partir du commit berdal84@b1fe138 (j'ai mergé ton master + un fix que tu m'avais suggéré pour l'unpiler), j'obtiens ces messages d'erreurs, une idée ?
Je build à partir de cette conf cmake:
# mirror
#-------
include( ${CMAKE_CURRENT_LIST_DIR}/mirror/mirror-config.cmake )
add_library(
mirror
STATIC
${MIRROR_SOURCES} )
target_include_directories(
mirror
PUBLIC
${MIRROR_INCLUDE_DIRS} )
Les erreurs lorsque je build la target mirror:

Suggestion - mirror an external defined member
It would be great to add a mechanism to serialize members when you can't modify it's class (external library for example).
Here a small example:
struct A {
ExternalClass m_member; // ExternalClass is included in a lib or from external files that you don't want to modify
MIRROR_CLASS(A)
(
MIRROR_MEMBER(m_member); // will not work
);
}
I propose for example:
struct A {
ExternalClass m_member; // ExternalClass is included in a lib or from external files that you don't want to modify
MIRROR_CLASS(A)
(
MIRROR_MEMBER(m_member, &methodToSerialize, &methodToDeserialize);
);
}
These two methods should be defined by the user.
We can also imagine an other solution by defining MIRROR_CLASS and _MEMBER outside the class/struct. With internal classes, it only requires to add friend keyword, for external we have to use getter/setters if they exist of course...
What do you think of that ?
missing space in MIRROR_CLASS_NOVIRTUAL causing compilation failure under MSVC 19
#define MIRROR_CLASS_NOVIRTUAL(_class, ...)\
public:\
::mirror::Class* getClass() const { return _class::GetClass(); }\
__MIRROR_CLASS_CONSTRUCTION(_class, __VA_ARGS__)
needs a space after public: to avoid a triple : when preprocessed.
I suggest to do the same with MIRROR_CLASS to avoid eventual future bugs if the first line do not start with the keyword static.
For information, error was hard to understand since I'm not under windows right now, I'm "debugging" using the CI console:
View.cpp
D:\a\Nodable\Nodable\src\app\include\nodable/Settings.h(63,1): error C2059: syntax error: ';' [D:\a\Nodable\build\src\app\nodable_app.vcxproj]
Fortunately, CLion gave me the preprocessed output:
I don't understand why GCC and clang under linux are compiling this fine.
MIRROR_PARENT avec une classe qui n'est pas parente
(Peut être que tu as déjà corrigé ça, je tappe sur le commit: 26e5102 du 3 Mai 2020 (plus 4 commits que je t'avais soumis pour des include de cstring))
J'ai remarqué une erreur que j'ai faite à l'instant dans le fichier: https://raw.githubusercontent.com/berdal84/Nodable/dev/0.8/sources/Node/GraphNode.h
Les faits:
GraphNodehérite deNode(qui hérite deObject).- je déclare par erreur
Component(qui hérite deObject) comme parent deGraphNode. - ça compile sans erreur avec
g++
Je suggère une static assert.
How to get a the type T of a given a TypeDesc* ?
I would like to get the type of a TypeDesc, for example something like that:
int myVar = 0;
TypeDesc* t = mirror::TypeDescGetter<decltype(myVar)>().Get();
using T = mirror::TypeDescT(t)::type;
T myOtherVar = 1; // T must be intRecommend Projects
