1. Introduction

Overview:

cfkit is a fast, cross-platform (Windows, macOS, Linux) command-line interface (CLI) tool built for Codeforces users to simplify competitive programming. It focuses on result comparison, fetching problem samples, and automating routine contest tasks, allowing users to focus more on problem-solving.

Features:

• Efficient Result Comparison: Compare floating-point numbers, allow any-order comparison, or use strict comparison.

• High Traffic Resilience: Parses problem data even under server load.

• Language Support: Compatible with all programming languages used on Codeforces.

• Fetch Problem Samples: Retrieves sample test cases for problems.

• Local Compilation and Testing: Compile and test solutions locally.

• Template-Based Code Generation: Generate code with templates, including timestamps and author info.

• Contest Problem Stats: Lists problem statistics for specific contests.

• Enhanced CLI Output: Distinguish correct and incorrect results easily with colored output.

2. Installation

Ensure Python is installed on your system. Then, run these commands in your terminal:
pip install cfkit
cf config all

And your are ready to go!

3. Usage

cf run 2000a.cpp    Compiles and tests your solution locally,
                    fetching and parsing missing sample test cases,
                    then comparing your output to the expected results with highlighted differences.

Options:

-o: Accept answers in any order.
-c: Run only custom samples or use custom input without comparing results.
-s: Do not ignore extra spaces during comparison.
-n: Do not ignore extra new lines during comparison.

cf gen 2000a    Generates a code file from the default (or chosen) template.

In your template code, you can include various placeholders. When you generate code from the template, these placeholders will be automatically replaced with specific values:

$%author%$ (e.g., ghoudiy).  
$%year%$ (e.g., 2024).  
$%month%$ (e.g., 9).  
$%day%$ (e.g., 7).  
$%hour%$ (e.g., 12).  
$%minute%$ (e.g., 05).  
$%second%$ (e.g., 00).  

cf parse 2000   Fetch all sample test cases from a contest.

4. FAQ

Q: How do I add a new test case?
A: To add a new test case, create two files: inK.txt and outK.txt, where K is a number. If you're using Linux or MacOs, omit the .txt extension (e.g., in1, ou1, in2, out2). You can create additional test cases by increasing the value of K (e.g., in1.txt, out1.txt, in2.txt, out2.txt).

Q: How to update cfkit package?
A: pip install --upgrade cfkit
