robertapp

Generates co-ed softball lineups. Give it a roster and who's showing up — it handles the rest.

What it does

• Fair playing time for everyone (±1 inning)
• Honors position preferences and avoids refused positions
• Co-ed rules: 3 girls minimum, 7 guys maximum on the field
• Late arrivals sit inning 1 and land at the bottom of the batting order
• Outputs a CSV with two batting orders (guys + girls) ready for Google Sheets

Setup

npm install

Usage

Edit src/data/roster.json to set your team and their position preferences. Edit src/rsvp.ts to set who's coming to the game and who's arriving late.

npm start

Lineup prints to console and saves to output/game-g1-lineup.csv.

Output format

Two batting orders in one CSV, separated by a blank row. Columns are innings 1–6. Position codes: P C 1B 2B 3B SS LF LCF RCF RF - (bench).
