Introduction
prog-shojin-util (pshu) is a CLI utility tool tailored to extract competitive programming problems not directly from contest platforms, but from blogs and websites that curate high-quality problems, particularly from renowned platforms like AtCoder and Yukicoder. By sifting through these selected compilations, users can focus on problems that are recommended by the community, filtering them based on criteria like AC status, date range, and more.
Features

User-Based Filtering: Focus on problems based on a specific user's activity on platforms like AtCoder.
Problem Status Filtering: Whether you're looking to find unsolved problems or revisit those you've already solved, prog_shojin_util has you covered.
Flexible Output: Obtain your results in various formats such as JSON, Markdown, CSV, and more.
Date-based Retrieval: Fetch problems available since a specific date for targeted practice sessions.

Integration with atcoder-cli
prog_shojin_util offers integration capabilities with atcoder-cli, an essential tool in the competitive programming community. By saving the fetched problems as contest.acc.json in a directory and then using atcoder-cli in that directory, you can streamline your problem-solving workflow.

Create a Workspace for Practice:
Begin by setting up a designated workspace for the problems.
mkdir practice
cd practice

Fetch Unsolved Problems with prog_shojin_util:
Fetch problems curated by a specific user (edge2992 in this case) from a Qiita post and save them in a format suitable for atcoder-cli.
pshu --atcoder-user edge2992 \
-t https://qiita.com/e869120/items/f1c6f98364d1443148b3 \
--status not-ac \
--output acc_json > contest.acc.json

Integrate with atcoder-cli:
With the contest.acc.json file at hand, you can now use the atcoder-cli to add the problems to your list of tasks.
acc add -c inquire

By following these steps, you can efficiently extract unsolved problems from a curated list, then download and submit tests using atcoder-cli.

Installation
To install prog_shojin_util, use the following command:
pip install prog_shojin_util

Ensure you have a compatible Python version installed.
Examples
To fetch unsolved problems from a specific URL for a given AtCoder user:
pshu --atcoder-user john_doe \
-t https://example.com/problems \
--status not-ac

To obtain all problems in CSV format for a Yukicoder user:
pshu --yukicoder-user jane_doe \
-t https://example.com/problems \
--status both --output csv

For detailed options and configurations, consult the Options section.
Options
Here's a breakdown of the available options in prog_shojin_util:

--atcoder-user TEXT: Specify the User ID for AtCoder to filter problems based on the user's activity.

--yukicoder-user TEXT: Specify the User Name for Yukicoder to filter problems based on the user's activity.

-t, --target TEXT: The base URL from which problem links will be fetched. This option is mandatory.

--status [ac|not-ac|both]: Filter problems based on their AC (Accepted) status.

ac: For problems already solved.
not-ac: For unsolved problems.
both: For all problems. The default is not-ac.

--output [json|markdown|csv|acc_json]: Choose the desired output format:

json: Standard JSON format.
markdown: Markdown format.
csv: CSV format.
acc_json: The format used by the atcoder-cli tool. The default is json.

--since DATE_FORMAT: Filter problems available since the specified date. Use the format 'YYYY-MM-DD' or 'YYYY-MM-DD HH:MM:SS'. The default is set to 2012-01-01.

--verbose: Enable this option for detailed logging, which aids in debugging.

For command-line help, use the --help option.
