SXHRYU’s gists

SXHRYU / pre-commit

Last active April 19, 2023 10:38

This is a gist of a pre-commit git hook using raw bash (not https://pre-commit.com/). It must be placed in `.git/hooks/pre-commit`. This gist enters `config` directory with `pyproject.toml` (which has `[mypy]` and `[flake8]` configs). From there it calls both `mypy` and `flake8`. Then it sets up environment variables for `pytest` and calls it.

	#!/bin/sh
	##########################################################################################################
	# I've used this pre-commit hook in my FastAPI app. It launches `bash` session (even on Windows) from the root dir of your project.
	# Meaning if you have a following project structure:
	###############################
	# app/ #
	# .git #
	# __pycache__ #
	# .mypy_cache #
	# config/ #

SXHRYU / str_to_datetime.py

Created January 6, 2023 18:55

Function that transforms string to `datetime.datetime` object with considerations for popular datetime formats. Meaning this function is format-agnostic and easily scalable (just add new formats).

	def transform_to_datetime(date_string: str) -> datetime:
	"""Normalises different datetimes and turns them into `datetime`
	objects.

	Needed in case time output from the site changes in the future.

	Parameters
	----------
	date_string : str
	Datetime presented in `str` format.

SXHRYU / vk_pre_commit

Created May 17, 2023 07:46

pre-commit hook I use for my work. I didn't update the `pre-commit` gist, because it's starting to get VERY different.
