a nice, cold, refreshing scripting language built in Rust
License: MIT License
my name's Justin! I'm a 24-year-old software engineer, and this is where I put all the miscellaneous things I work on in my free time.
if you wanna get a grasp of some of the things I'm currently working on, check my pinned repositories!
I want a type system like TypeScript's that makes me feel all-powerful and godlike in defining the structure of my objects. is that so much to ask?
type Option<T> = enum {
Some(T),
None,
};
type DataWrapper<T> = #{
"data": T
};
type TwitchUser = #{
"id": String,
"login": String,
"display_name": String,
"type": String,
"broadcaster_type": String,
"description": String,
"profile_image_url": String,
"offline_image_url": String,
"view_count": Number,
"email": String,
"created_at": String,
};
fn get_user(id: Number): Option<DataWrapper<TwitchUser>> {
let user = // get the user from the Twitch API somehow...
user
};
// `user` is inferred to be of type `Option<DataWrapper<TwitchUser>>`
let user = get_user(141981764);
if let Some(user) = user {
log("we got a user!");
} else {
log("we probably have to refresh our key...");
};
the following code throws a type error at runtime:
let test = "1" + {
let test2 = 15;
test2 / 3
};
this is the debug result:
== code ==
0000 #0001 Constant 0001 "1"
0001 #0002 Constant 0002 15
0002 #0003 GetLocal(0)
0003 #0003 Constant 0003 3
0004 #0003 Divide
0005 #0004 Pop
0006 #0004 Add
0007 #0004 DefineGlobal(0)
0008 #0004 Return
0001 #0001 Constant 0001 "1"
["1"]
0002 #0002 Constant 0002 15
["1"][15]
0003 #0003 GetLocal(0)
["1"][15]["1"]
0004 #0003 Constant 0003 3
["1"][15]["1"][3]
0005 #0003 Divide
[!] Runtime error: Type error: expected value of type "number", found "1".
resolving locals doesn't work when there are other values in the stack, as it recognizes 15 as the value of the first local and assumes it to be at stack index 0, when it isn't. this is probably covered in the book during the function chapter but I haven't read it yet
