Clone this repository and run npm i -g . at the root folder.

cf-crawler samples --platform=cf --id=1516

or simply

cf-crawler -p=cf -i=1516

This creates one folder for each problem, each containing your template CPP code and the sample files.

You first need to start the submission server.

cf-crawler server --platform=cf

or

cf-crawler server -p=cf

It will ask for your username and password. Once it successfully logs in, you need keep the process running as it is running a server that will submit your solutions to the selected platform.

To submit a solution, run

cf-crawler submit --platform=cf --id=1516 --problem=A solution.cpp

or

cf-crawler submit -p=cf -i=1516 -P=A solution.cpp

If you used the samples command, the Makefile in each problem's folder has a command to submit your code, so you can simply do make submit.

So far the only implemented platform is Codeforces. I have plans of implementing this for Google competitions as well (Kickstart / GCJ), but I'm too lazy at the moment.
