Nimc
command line utilty in order to create Defold naitive extensions in Nim .
♠ Install
pip install nimc
♠ Getting started
open terminal in root path of defold project :
♠♠ Create Extension named ext :
nimc init ext
♠♠ Build project :
nimc build ext
♠♠ Edit Nim code inside ext/extext.nim :
Note :
-
To export the functions from nim it must be add exported public through
*annoation . -
To export the functions from nim it must be added with pargma through
{.cdecl,exportc,dynlib.}annoation . -
After any of edit of nim file make sure to call build command
nimc build ext -
the
nimcwill take care of cpp file to export functions !!
proc add*( a : cint , b:cint ): cint {.cdecl,exportc,dynlib.} =
return a + b
proc function*( a : cint , b:cint , c: cint ): cint {.cdecl,exportc,dynlib.} =
return a + b * 2
this will generate in cpp file :
static int nim_add(lua_State* L)
{
int a = luaL_checkinteger(L, 1);
int b = luaL_checkinteger(L, 2);
int result = add(
a ,
b ,
) ;
lua_pushinteger(L, result);
return 1;
}
static int nim_function(lua_State* L)
{
int a = luaL_checkinteger(L, 1);
int b = luaL_checkinteger(L, 2);
int c = luaL_checkinteger(L, 3);
int result = function(
a ,
b ,
c ,
) ;
lua_pushinteger(L, result);
return 1;
}
static const luaL_reg Module_methods[] =
{
{"add", nim_add},
{"function", nim_function},
{0, 0}
};
♠♠ Usage of naitive extension :
in any script file :
local result = ext.add(10,12)
print(result)
