Codeforces cli tool

This is a command line tool for Codeforces.

Usage

There are two modes available: interactive and non-interactive mode.

To use in interactive mode:

$ codeforces
> <command> [command args]

in non-interactive mode:

$ codeforces <command> [command args]

use exit to exit in interactive mode.

Commands

Current supported commands are:

login

Usage: login

This command only available in non-interactive mode. Input your handle and password when it prompts.

submit

Usage: submit </path/to/file> [--watch] [--contest <contest_id>/--gym <gym_id>/--mashup <mashup_id>]

Now only support cpp files, and default to use C++11. Now you can run set init to setup default complier based on file extensions. More information, see Supports and set.

If watch option is provided, a real-time update will active until verdict reveal. Update rate depend on network speed. If this field is empty, the submission id will be printed.

One can add --contest options to specify which contest will be submitted to. The priority of this option is higher than file name described below. Same as --gym and --mashup.

Notice that if this command are run in interactive mode, you have to login in non-interactive mode first. In case of non-interactive mode, you can login at same time when you submit.

File Name

File should be named as problem.ext. For example, 977D.cpp is a C++ solution for problem 977D, and this is not case sensitive.

If --contest(or another two options) are provided, file can be named as *index.ext. That is, meowF.cpp will be send to problem F of the specified contest.

set

Usage: set <init/cookie/compiler> [compiler options]

Only set cookie are available in interactive mode. Others are only available in non-interactive mode. Directory ~/.codeforces-cli-tool must exist when execute this command except set init.

init

Run set init at after install this package and follow the instruction to setup. Unless you are sure to refresh both cookie and compiler, do not run init after first time using it. This package will use ~/.codeforces-cli-tool to store some file.

cookie

The only way to logout from Codeforces currently.

compiler

If no following options, this will lead you to set all choosable compiler for each extensions, or only the specific extentions will be set. Options are c,cpp,and py.

Arguments

There are some common arguments can be used:

• --config-path <path>: specify the config directory. Default is $HOME/.codeforces-cli-tool.
• --cookie-file <file>: specify the cookie file name. Related to config-path, default is cookie.json.
• --compiler-file <file>: specify the compiler file name. Related to config-path, default is compiler.json.

Installation

$ npm install -g codeforces-cli-tool
$ codeforces set init

You can also manually add a empty file ~/.codeforces-cli-tool/cookie.json to use default compiler settings without running init.
