CodeByAidan / point.py
Created June 14, 2024 14:30
yet another point example in python, but with ctypes, and heavy type annotations, since who doesn't like them? 😅
from __future__ import annotations
import ctypes as ct
class Point(ct.Structure):
_fields_: list[tuple[str, ct._SimpleCData]] = [("x", ct.c_int), ("y", ct.c_int)]
def __repr__(self) -> str:
return f"({self.x}, {self.y})"

Created June 13, 2024 19:59
Get a variable's name that was passed into a function in Python using this little snippet!
import inspect
def foo(bar) -> str | None:
bar_name: str = [
name
for name, obj in inspect.currentframe().f_back.f_locals.items()
if obj is bar
][0]
return bar_name

CodeByAidan / type-annotate-checker.py
Created June 13, 2024 19:12
A decorator using only built-in libraries in Python, to type-hint/annotate parameters.
import functools
import sys
from typing import Any, Callable, TypeVar
T = TypeVar("T")
def reveal_type[T](obj: T, /) -> T:
print(f"Runtime type is {type(obj).__name__!r}", file=sys.stderr)
return obj

CodeByAidan / fib.ml
Created June 12, 2024 16:03
another fibonacci function, but this time, OCAML! Pretty simple!
let fib n =
let rec aux acc n2 n1 = function
| 1 -> acc
| c -> aux ((n2 + n1) :: acc) n1 (n2 + n1) (c - 1)
in
List.rev(aux [1; 0] 0 1 (n - 1))
;;
let () =
let fibs = fib 50 in

CodeByAidan / time-command-execution.ps1
Created June 12, 2024 13:28
Found a neat one-liner way of timing the last command you ran using PowerShell! For example, run a python file, so like `python regex_playground.py` then run the one-liner and it returns `00:00:00.3471487`!
(Get-History -Count 1 | Select-Object -Property @{Name = 'ts'; Expression = { $_.EndExecutionTime - $_.StartExecutionTime} }).ts.ToString()

CodeByAidan / thread-lock-type-safe-decorator.py
Created June 10, 2024 15:39
fun example of using a type-safe decorator providing a threading.Lock
from collections.abc import Callable
from threading import Lock
from typing import Concatenate
my_lock = Lock()
def with_lock[**P, R](f: Callable[Concatenate[Lock, P], R]) -> Callable[P, R]:
"""A type-safe decorator which provides a lock."""
