HackerRank Wget - download your sumbitted solutions offline

What

Downloads your solutions from HackerRank to your computer. Like this.

Why

To keep track of your performance, reflect on old code and improve.

Why Scala

A dynamic language like JavaScript or Python could have been handier for this task, but why not?

How to use

Copy application.conf.template to application.conf, add any additional settins from reference.conf. You need to log into Hackerrank in your browser and copy the value of your hrank_session cookie.

Note:

It is pretty slow right now as all the downloads are synchronous, on the bright side it does not DDOS HackerRank API.

So plug in your laptop and go do something useful.

1. Install sbt: https://www.scala-sbt.org/1.x/docs/Setup.html
2. Run sbt in the root folder
3. Wait for sbt to download all the sbt dependencies…
4. Inside sbt console run compile command
5. Wait for sbt to download all the project dependencies and compile the source code…
6. Inside sbt console run run command
