Light tool to extract CodeForces problems into PDF files

codeforces2pdf

Extract CodeForces problems to PDF files

A remake of https://github.com/AliOsm/codeforces2pdf, with Selenium replaced by requests + BeautifulSoup + either mathjax or make4ht latex renderer.

Prerequisites

• Python 3.9+
• mathjax-node-cli (for default and graphics mode)
• make4ht (for fast mode)
• Tested on Ubuntu 22.04.1 LTS

Quickstart

Install dependencies with poetry

poetry install

or with raw pip

pip install -r requirements.txt

Extract a problem from a contest:

python3 codeforces2pdf.py [-d OUT_DIR] [-f|-g] <contest_id> <problem>

Notes

With -f | --fast the utility executes a tiny bit faster and requires only TexLive distribution, but produces simpler and much less sane views of latex formulas. With -g | --graphics the formulas are rendered to SVGs, one may prefer this rendering, but it consumes lots of CPU time.
