Codeforces Tool is a command-line interface tool for Codeforces.

It's written in golang (without any browser driver). And it's fast, small(only about 7 MB), cross-platform(Windows, macOS, Linux) and powerful.

You can find the source and binary files in my git repo https://github.com/xalanq/cf-tool

You can download the tool from release page https://github.com/xalanq/cf-tool/releases

Features:

  • Support Contests, Gym, Groups and acmsguru.
  • Support all programming languages in Codeforces.
  • Submit codes.
  • Watch submissions' status dynamically.
  • Fetch problems' samples.
  • Compile and test locally.
  • Clone all codes of someone.
  • Generate codes from the specified template (including timestamp, author, etc.)
  • List problems' stats of one contest.
  • Use default web browser to open problems' pages, standings' page, etc.
  • Setup a network proxy. Setup a mirror host.
  • Colorful CLI.

I have tested the tool for contest Codeforces Round #551 (Div. 2).

It's not a cheating tool, but a tool for beautiful life :)

Pull requests are always welcome.

Let's simulate a competition.

cf race 1136 or cf race https://codeforces.com/contest/1136

To start competing the contest 1136!

If the contest has not started yet, cf will count down. If the contest have started or the countdown ends, cf will use the default browser to open dashboard's page and problems' page, and fetch all samples to the local.

cd ./cf/contest/1136/a (May be different from this, please notice the message on your screen)

Enter the directory of problem A, the directory should contain all samples of the problem.

cf gen

Generate a code with the default template. The filename of the code is problem id by default.

vim a.cpp

Use Vim to write the code (It depends on yourself).

cf test

Compile and test all samples.

cf submit

Submit the code.

cf list

List problems' stats of the contest.

cf stand

Open the standings' page of the contest.

FAQ

I double click the program but it doesn't work

Codeforces Tool is a command-line tool. You should run it in terminal.

I cannot use cf command

You should put the cf program to a path (e.g. /usr/bin/ in Linux) which has been added to system environment variable PATH.

Or just google "how to add a path to system environment variable PATH".

How to add a new testcase

Create two extra testcase files inK.txt and ansK.txt (K is a string with 0~9).

Enable tab completion in terminal

Use this Infinidat/infi.docopt_completion.

Note: If there is a new version released (especially a new command added), you should run docopt-completion cf again.
