cptool

A competitive programming tool to automate downloading of test cases and creation of code files.

What can you do with this?

1. This program can generate test cases for problems from atcoder.jp and codeforces.com including gym.
2. Parse a whole contest -> will save the sample input/output and generate code for selected languages.
   • For parsing whole contests, links can be used. Links are not supported for individual problems
   • For gym, only links are supported.
   • AtCoder links should end in /tasks. Meaning, link of contest's tasks page should be provided.

# format: cf [-g|-gen] <contest/problem id>
> cf -gen 1345
> cf -g abc161

> cf -g https://codeforces.com/contest/564
> cf -gen https://codeforces.com/gym/353232
> cf -g https://atcoder.jp/contests/dp/tasks/

3. Parse a single problem.

> cf -gen abc160_d

4. Test a code against parsed input-output.

# format: cf [-j|-c[-d]] [-r] <problem>

# test java code
> cf -j a

# test cpp code
> cf -c a

# test cpp code with debug options enabled
> cf -c -d a
> cf -cd a

5. Run the code for a specific problem and input custom test case from console.

# java
> cf -jr b

# cpp
> cf -c -r

6. Add custom input/output to the problem. It will be used to test against next time.

> cf -a d
Enter input:
<Enter custome input here>
<Press Enter>

Enter output:
<Enter corresponding correct ouput here>
<Press Enter>

How to use?

Make

1. Install dependencies using the below command

pip3 install -r requirements.txt

2. Make changes in the settings.yaml file according to your needs
   • set which languages you need (supports only java acd cpp)
   • set template path for the languages required
   • Download and save cookies for both, atcoder and codeforces, sites
   • set the location of cookies in settings
3. Run the following command

make

or

make create
make copy

This will first create the cf excecutable and will then copy it to /usr/local/bin/. So that it is available in path and can be used from anywhere.

Commands

Use cf -h to see the help message: Note: -d can only be used with -c|-cpp|--cpp cpp options.

usage: cf [-h] [-g] [-p] [-m] [-a] [-r] [-j] [-c] [-d] problem
