Options to use while running script

Script hsc supports following options

• help: -h or --help
• username: -u or --username -> username of hackerrank profile
• password: -p or --password -> password of hackerrank profile
• limit: -l or --limit -> no. of solutions to be downloaded
• config: -c or --config -> path of config file

Usage:
We can use above script helpers as

hsc -l 34 -p testpassword -u testuser

We can also use config file to download solutions
Let config file be /etc/user.yaml

username: testuser

hsc -c /etc/user.yaml -l 34 -p testpassword

There's no need of requesting the number of submissions again, because we have stored the total number of submissions while authenticating the user. We can directly use crawler.total_submissions.

Issue Found

Description

When you pass wrong username and password either from the config file or from the command line, it will retry with those credentials only, because earlier when the credentials were being taken from the user, and if found wrong, then it used to ask the user again. But now it will go into an infinite loop (which can still be cancelled by pressing Ctrl + C), which is not the right way.

Reference Screenshot

Solution

We can check if the credentials are taken from either command line or config file, and accordingly terminate the program if auth was unsuccessful.
