# HackerRank Submission Downloader
HackerRank Submission Downloader allows you to download submissions for a contest
in HackerRank.
The tool organizes the submissions according to the problem name and their programming language and then by account name.
For example,
```bash
out/2020-03-01-06-01
├── a-walk-to-remember-1
│ ├── c
│ │ ├── Cygnus_UOK.c
│ │ ├── KingCoders_SEUSL.c
│ │ └── StackTrace_NSBM_.c
│ ├── cpp
│ │ ├── BlackHawks_USJ.cpp
│ │ ├── Code_Clan_RUSL.cpp
│ │ ├── Cyborgs_USJ.cpp
│ │ ├── FRIDAY_USJ.cpp
│ │ ├── JPAC_UOP.cpp
│ │ ├── Paradox_UOJ.cpp
│ │ └── XCODERS_UOP.cpp
│ ├── csharp
│ │ └── CodeMart_UOR.cs
```
## Development
This tool was written in Go
1. Install Golang 1.14 or newer
2. Clone the repo in your local machine
3. Run `go build` to build binary for your platform
### To cross compile
Run `chmod +x ./build/build.sh && ./build/build.sh`
## How to use
Download binary for your platform from [release](https://github.com/kasvith/hackerrank-dl/releases) page (or build yourself :hammer:).
The usage of the tool is simple. You have to provide a `config.yaml` in your current working directory and tool will pick this up. `config.yaml` contains all the necessary info to download submissions from a hackerrank contest.
> Note: You should be a moderator or an administrator of the contest in order to use this tool for download submissions
sample config file `config.yaml` is shown below
```yaml
# slug name of the contest
contest: our-contest
# browser cookies for HackerRank as semicolon seperated string
cookies: >-
abc=123; xyz=123;
# output directory
output: results
# limit 5 parallel download threads
parallelDownloads: 5
# wait time between downloads in seconds
waitTime: 1
# burst per wait time
rate: 10
```
Run `./hackerrank-dl` with `config.yaml` in the working directory to start the magic.
## How to get contest slug name
1. Go to HackerRank
2. Go to your contest
3. Slug name is in the pattern of `https://www.hackerrank.com/aces-coders-v8`
4. In here `aces-coders-v8` is the **slug name**
5. Copy it and use it in `config.yaml`
## How to get HackerRank browser cookies
HackerRank does not provide a public API, thus we have to use browser cookies for authentication
> Following instructions are based on Chrome
1. Open Chrome
2. Login to HackerRank
3. Make sure you are an admin/moderator of your contest
4. Install [EditThisCookie](https://chrome.google.com/webstore/detail/editthiscookie/fngmhnnpilhplaeedifhccceomclgfbg/related?utm_source=chrome-ntp-icon) browser extension for chrome
5. Open extension
6. Click **Settings** Icon
7. Set **Choose preferred export format for cookies** to **Semicolon seperated name=value pairs**
8. Open up `https://hackerrank.com`
9. Open `EditThisCookie` extension
10. Click `Export` button (arrow out)
11. Paste the value for cookies in `config.yaml`
