I first must push a new thread using lua_newthread
, then calling luaL_loadfile
and instead of lua_pcall
, calling lua_resume
.
I rewrote this in C to check if there was possible stack unwinding issues from Lua to Python.
void l_dbg_count(lua_State *L, lua_Debug *ar) {
if(ar->event == LUA_HOOKCOUNT) {
printf("yielding
");
lua_yield(L, 0);
}
}
...
int main(int argc, char **argv) {
lua_State *L = luaL_newstate();
luaL_openlibs(L);
lua_sethook(L, l_dbg_count, LUA_MASKCOUNT, 5);
lua_State *L_t = lua_newthread(L);
luaL_loadfile(L_t, "test.lua");
int ret = lua_resume(L_t, 0);
while(true) {
if(ret != 0 && ret != LUA_YIELD) {
fprintf(stderr, "%s", lua_tostring(L_t, -1));
break;
} else if(ret == LUA_YIELD) {
printf("resuming
");
ret = lua_resume(L_t, 0);
} else {
break;
}
}
lua_close(L);
return EXIT_SUCCESS;
}
This however does break the coroutine library from working it seems, so currently looking into a possible fix for that.
