bracket-creator

A CLI to create kendo tournament brackets

Usage

Download the pre-compiled binaries from the release page page and copy them to the desired location.

To use the web front end run this command and open your browser on http://localhost:8080

bracket-creator serve

You can also use docker with:

docker run -p 8080:8080 ghcr.io/gitrgoliveira/bracket-creator/bracket-creator:latest

or docker-compose to run the web server:

docker-compose up -d

There's also a CLI. To learn how to use the CLI run:

bracket-creator --help
bracket-creator create-pools --help
bracket-creator create-playoffs --help

Example to build the tool from source:

make go/build

Input file format

The input file can be a simple list of names or a CSV formatted file. For example:

First_Name Last_Name, Dojo

For teams, it should be just one team per line.

When using the CSV formatted style, Dojo is only used to try to ensure players/teams don't meet someone of the same dojo when doing pools.

Customizing the web server

To set the listen address and port run:

bracket-creator serve --listen-address 0.0.0.0 --listen-port 8080

You can also use the environment variables:

export BIND_ADDRESS=0.0.0.0
export PORT=8080

Examples

See also the example files created by the Makefile:

./bin/bracket-creator create-pools -s -p 4 -f mock_data.csv -o output.xlsx

With 5 players per team:

./bin/bracket-creator create-pools -t 5 -f mock_data.csv -o output.xlsx

How to Use the output files

All generated output files are based on the template.xlsx file and to customise it you will need to edit the final file.

To be able to print the tree, you will need to reset the width and height in the Page Layout tab.

On the day of the tournament

These files are generated to be uploaded to Google Drive (or similar), so all shiai-jo tables are in sync during the tournament, working from the same file.
