> git clone https://github.com/Eliasin/elo.git
> cd elo
> cargo build --release

Usage

USAGE:
    elo [OPTIONS] --matches <FILE> --output <FILE> --standings <FILE>

matches should be the path to a file containing a JSON representing a list of

{
    winner: String,
    loser: String,
    series: SeriesKind
}

where winner and loser are the names of the winning and losing teams where SeriesKind can be the string "Bo1", "Bo3" or "Bo5"

standings should be the path to a file containing a JSON representing team standings as keys from name to rating

{
	"team_name1": number,	
	"team_name2": number,
	...
}

where there can be any number of team, elo pairs

Configuration

The configuration file determines the weights for Best of N series and determines the K values for different elo brackets. It is in config.json by default but this can be overriden with the --config or -c flag.

The configuration file should be a JSON representing

{
	"bo1_score": number,
	"bo3_score": number,
	"bo5_score": number,
	"k_brackets": [
		{
			"start": number,
			"k": number
		},
		{
			"start": number,
			"k": number
		},
		...
	]
}
