Local Data Storage

• Characters and app settings are stored locally in an embedded SurrealDB (SurrealKV) datastore at characters.surrealdb.
• By default on Windows this lives under %LOCALAPPDATA%\DnDGameRolls\characters.surrealdb.
• Older installs may have a legacy SQLite database at %LOCALAPPDATA%\DnDGameRolls\characters.db; on first run the app can migrate data into SurrealDB.

Releasing the CLI (crates.io)

The publishable CLI crate lives at crates/dndgamerolls-cli.

• Dry-run publish locally: cargo publish -p dndgamerolls-cli --dry-run
• GitHub Actions workflow: .github/workflows/publish-cli-crates-io.yml (manual dispatch; uses CARGO_REGISTRY_TOKEN)

dndgamerolls --dice 2d6 --dice 1d20

# Launch with skill modifier applied
dndgamerolls --dice 1d20 --checkon stealth

dndgamerolls --cli --dice 1d20 --checkon stealth --advantage

# Traditional subcommands also work
dndgamerolls skill stealth
dndgamerolls --advantage skill perception
dndgamerolls attack dagger
dndgamerolls stats
