This project aims to support the creation of any tournament.
Current features
- Group tournament creation
- Group tournament stats
Planned features
- Elimination tournaments
- Double elimination
- Round robin
To create a group tournament with 2 groups where all teams in each group meet one time simply do the following.
package main
import (
"fmt"
"github.com/tournify/tournify"
"math"
"math/rand"
)
func main() {
teams := []tournify.Team{
{ID:0},
{ID:1},
{ID:2},
{ID:3},
{ID:4},
{ID:5},
{ID:6},
{ID:7},
{ID:8},
{ID:9},
{ID:10},
{ID:11},
{ID:12},
{ID:13},
{ID:14},
{ID:15},
{ID:16},
}
teamInterfaces := make([]tournify.TeamInterface, len(teams))
for i := range teams {
teamInterfaces[i] = &teams[i]
}
// The CreateGroupTournamentFromTeams method takes a slice of teams along with the group count and meet count
tournament := tournify.CreateGroupTournamentFromTeams(teamInterfaces, 2, 1)
for _, game := range tournament.GetGames() {
game.SetScore(randomEvenFloat(0.0, 10.0), randomEvenFloat(0.0, 10.0))
err := tournament.SetGame(game)
if err != nil {
panic(err)
}
}
// The print method gives us a string representing the current tournament
fmt.Println(tournament.Print())
}
func randomEvenFloat(min float64, max float64) float64 {
return math.RoundToEven(min + rand.Float64() * (max - min))
}This will print something similar to the following output.

You can also print statistics for the current tournament if we add the following code at the end of the main function.
stats, err := tournify.GetGroupTournamentStats(tournament, 3, 0, 1)
if err != nil {
panic(err)
}
fmt.Println(tournify.PrintGroupTournamentStats(stats))
This will print the stats for the current tournament which will look similar to the following example
Group Team Played Wins Ties Losses +/- Diff Points
0 1 7 5 1 1 36/23 13 16
0 5 7 5 1 1 35/26 9 16
0 4 7 4 1 2 31/24 7 13
0 6 7 3 1 3 36/37 -1 10
0 2 7 3 0 4 41/43 -2 9
0 7 7 3 0 4 33/37 -4 9
0 0 7 1 2 4 25/33 -8 5
0 3 7 1 0 6 18/32 -14 3
1 16 9 5 2 2 53/33 20 17
1 11 9 5 2 2 48/38 10 17
1 12 9 5 2 2 45/45 0 17
1 15 9 5 0 4 48/54 -6 15
1 13 9 3 4 2 35/18 17 13
1 10 9 3 1 5 46/56 -10 10
1 -1 9 0 9 0 0/0 0 9
1 8 9 2 2 5 38/40 -2 8
1 9 9 1 5 3 15/31 -16 8
1 14 9 1 3 5 41/54 -13 6
Teams are ordered by the number of points. If a team has an equal number of points as another the diff value is used as a tie-breaker. If the diff value is also the same then the points scored against other teams is used.
Elimination tournaments are also possible. Here is an example of an elimination tournament with 8 teams:
package main
import (
"fmt"
"github.com/tournify/tournify"
"math"
"math/rand"
"time"
)
func main() {
teams := []tournify.Team{
{ID: 0},
{ID: 1},
{ID: 2},
{ID: 3},
{ID: 4},
{ID: 5},
{ID: 6},
{ID: 7},
}
teamInterfaces := make([]tournify.TeamInterface, len(teams))
for i := range teams {
teamInterfaces[i] = &teams[i]
}
tournament := tournify.CreateEliminationTournamentFromTeams(teamInterfaces)
for _, game := range tournament.GetGames() {
err := tournament.SetGameScore(game, randomEvenFloat(0.0, 100.0), randomEvenFloat(0.0, 100.0))
if err != nil {
panic(err)
}
}
// The print method gives us a string representing the current tournament
fmt.Println(tournament.Print())
// Loop eliminated teams
fmt.Println("Eliminated teams")
for _, team := range tournament.GetEliminatedTeams() {
fmt.Printf("Team ID: %d\n", team.GetID())
}
fmt.Println()
// Loop remaining teams
fmt.Println("Remaining teams")
for _, team := range tournament.GetRemainingTeams() {
fmt.Printf("Team ID: %d\n", team.GetID())
}
}
func randomEvenFloat(min float64, max float64) float64 {
rand.Seed(time.Now().UnixNano())
return math.RoundToEven(min + rand.Float64()*(max-min))
}The output from the above code will be something like the following:
