Hello all,
I have to admit that I am a C newbie. I want to use Go's slog mechanism
with variable arguments (for example slog.Warn("message", "argument1",
"value of argument1"))
The Go function would be something like this:
//export sdLogMessages
func sdLogMessages(level *C.char, message *C.char, arguments []string) {
goLevel := C.GoString(level)
goMessage := C.GoString(message)
var argsAny []any
for _, arg := range arguments {
argsAny = append(argsAny, arg)
}
switch goLevel {
case "warn":
slog.Warn(goMessage,argsAny...)
}
}
but I have no idea how to create a GoSlice with the char* entries from the
C part
This is not strictly related to the probelm, but anyhow: My current C part
is a Lua library:
static int lua_logmessages(lua_State *L) {
const char *loglevel = luaL_checkstring(L, 1);
const char *message = luaL_checkstring(L, 2);
int a = lua_gettop(L); // number of items on the stack
char* arg;
// ***** here I'd like to create either a GoSlice (args) with i char*
strings
// or pass char** to the Go function.
for (int i = 3; i <= a; i++) {
arg = luaL_checkstring(L,i);
printf("arg = %s\n",arg);
}
// sdLogMessages(loglevel,message,args);
return 0;
}
Should I create a GoSlice from char* entries or should I use another way to
create an array of char* strings?
How would I do that?
Thank you very much
Patrick
