 viferga | in our case, all our languages we support don't have that facility, you usually have to create a new function if you want to mutate the signature | 15:48:01 |
| viferga | this changes with classes, we are doubting how to implement them right now, at the moment we aren't tracking the signatures of the methods due to this behavior | 15:48:48 |
| viferga | but this is problematic with Java, and I'm still doubting how to solve this | 15:49:03 |
 darabi | But for JS, you said that there is no type inference, so the loader cannot know the type of the return value. | 15:51:05 |
| darabi | Or did I get something wrong? | 15:51:09 |
| viferga | ah, well, you can change the number of arguments for example | 15:51:10 |
| viferga | you have to create a new function | 15:51:10 |
| darabi | I see. | 15:51:11 |
| viferga | but let's say, typescript, it would be the same | 15:51:11 |
| darabi | I'm just struggling to convert the result of metacallv to something useful in my host language | 15:51:11 |
| darabi | And metacall_value_id gives me enough information to do the conversion dynamically | 15:51:28 |
| viferga | that's right, you can get the type of a returned value with that | 15:52:00 |
| darabi | For node and a returned double, I get METACALL_DOUBLE.
But for py and a returned String, I get METACALL_INVALID. Does that mean that something went wrong calling the function? | 15:53:14 |
| viferga | probably | 15:55:36 |
| viferga | you can enable debug logs to see more info | 15:55:57 |
| darabi | I have already | 15:56:04 |
| viferga | mmmm, what happens if you return a double from python? like 3.9 | 15:57:54 |

| darabi | Loading test.py seems to work without problems. I also load sum.js with node. | 15:58:58 |
| darabi | Calling sum from sum.js leaves a trace in the log, but calling py_test from test.py doesn't. | 15:59:35 |
| viferga | [Tue Jun 22 15:21:34] #47 [ 679 | loader_impl_load_from_file | /usr/local/metacall/source/loader/source/loader_impl.c ] @Debug : Loader interface: 0x7f233c24b5c0; Loader handle: (nil) | 15:59:56 |
| viferga | seems like the handle is NULL | 16:00:02 |
| darabi | When loading several node scripts, I can always pass NULL. When I load another language for the first time, I have to use the handle which I received from the first call? | 16:02:44 |
| viferga | you can pass NULL too | 16:03:09 |
| viferga | well, it would be better if you show me your code | 16:03:24 |
| viferga | otherwise I don't have a detailed idea of what you mean | 16:03:45 |
