options:
  -h, --help    show this help message and exit

From this we can tell, that cf-auto is capable of:

• creating necessary files for the specified contest OR problem
• compiling and running your C++ code with further comparing with fetched test cases: Right here, right now.

Usage example

Use cf-auto and solve problems in one directory

Create files for the contest

cf-auto create C 2000

The resulting directory has the following structure:

2000
├── A
│   ├── 2000A.cpp
│   ├── ans.txt
│   ├── in.txt
│   └── out.txt
├── B
│   ├── 2000B.cpp
│   ├── ans.txt
│   ├── in.txt
│   └── out.txt
├── C
│   ├── 2000C.cpp
│   ├── ans.txt
│   ├── in.txt
│   └── out.txt
etc.

Create one problem to practice on

cf-auto create P 2000 A

And you get:

practice/
└── 2000_A
    ├── 2000_A.cpp
    ├── ans.txt
    ├── in.txt
    └── out.txt

Demo

Installation

1. Clone the repo

git clone https://github.com/Lassa30/cf-auto.git

2. Install dependencies

pip install -r requirements.txt

3. Run cf-auto

python cf-auto.py --help

Optional:

1. Add this alias to ~/.bashrc to run cf-auto without interpreter name

alias cf-auto="python3 cf-auto.py"

2. Create a virtual environment before you install the dependencies

python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Configuration

Note: the configuration is too simple and stupid, just hardcoded

Parameters examples:

TEMPLATE_PATH = "cf_template.cpp" # i.e. the path to your template file
BUILD_OPTIONS = "-Wall -g0 -O0 --std=c++20" # i.e. just some options for g++

TODOs

• Nicer logging
• Use and test by yourself
• Add example usage
