aocstarter 0.2.0

Advent of Code Framework

https://adventofcode.com/
A framework for implementing Advent of Code solutions in Python.
Quick Start
Pip install the project so you have access to the aoc command.
pip install aoc-starter

Create an empty directory you want to write your solutions in.
aoc init

Now, you are ready to start implementing your solutions!
aoc create 01 --year 2021

This will create python file, 2021/day01.py, where you'll implement the solution.
After you've implemented the solution, you can run it with:
aoc run 01 --year 2021 -i input.txt

Solution Implementation
The file 2021/day01.py will have a concrete class, Solution01 that extends the base Solution class from aoc-starter.
There are a variety of methods that must/can be defined to best implement your solution.
Part Functions
These are the only abstract methods in the base class and therefore must be implemented.
def _part_one(self) -> int:
...

def _part_two(self) -> int:
...

These functions should return the integer answer to Advent of Code problems. The input data can be accessed using the data property, self.data.
Parsing data
There are three functions you can use to parse the data:
def _get_data(self) -> list[Any]:
...

def _get_data_for_part_one(self) -> list[Any]:
...

def _get_data_for_part_two(self) -> list[Any]:
...

The _get_data function is the default, so if you don't implement one of the others then _get_data is used. If there are differences in how the data should be parsed between each part you can use the more specific functions.
Inside these functions, you need to return the data as a list, down the line this return value is stored in self.data.
The input handler
The solution base class has a property input, that is of type aoc.InputHandler. This object is the intermediary between the raw data and the solution. When parsing data, you can use the self.input.as_list function to interact with the raw content.
# default, return the content as a list of strings
def _get_data(self) -> list[str]:
return self.input.as_list()

# parse as a certain type
def _get_data(self) -> list[int]:
return self.input.as_list(int)

# use a custom parser
def _get_data(self) -> list[tuple[str, int]]:
def parser(content: str, **kwargs) -> tuple[str, int]:
key, val = content.split(": ")
return key, int(val)

return self.input.as_list(parser)

Reformatting input file
You can use the _reformat_data function to change how the input data looks.
Pop Lines
Sometimes the input file has a line at the beginning that is different from the actual data. The InputHandler has a method pop_line that removes and returns the first line in raw content. If you want to use this before any reformats happen, you can override the _pop_lines method in the solution.
class Day01(Solution):

first_line: str

def _pop_lines(self) -> None:
self.first_line = self.input.pop_line()
