Vexillologist

Discord bot that watches for scores from the following "dle" games:

• Flagle
• FoodGuessr
• Geogrid

Scores are stored by user and guild ID, and then both daily and all-time leaderboards are available for each game via the /leaderboard slash command.

Development

Set up Rust toolchain

If you're using rustup, there's a rust-toolchain.toml file in the root of the repository that specifies the toolchain needed to build the crate. To format the code, though, you'll have to install a nightly toolchain and ensure it contains the rustfmt component, and then format with cargo +nightly fmt or rustup nightly run rustfmt.

If you're using Nix, there's a flake that defines a dev shell with a Rust toolchain (including nightly rustfmt) and a few other useful tools included. You can load this either with nix develop or via the direnv .envrc file, and then build the crate as normal with cargo build. Formatting should work out of the box with cargo fmt or rustfmt.

There's also a Nix package defined in the flake for release builds.

Cutting a Release

This project uses Conventional Commits, and convco is included in the Nix devShell to assist with this.

The overall list of things that has to happen for each release is as follows:

• The commit that changes the version should use the message release: v<version>.
• That commit should update the version in Cargo.toml to match the version output by convco version --bump.
• That commit should include an updated Cargo.lock file, most easily generated by running a cargo build after updating the version.
• That commit should include an updated Cargo.nix file, generated using cargo2nix -ls > Cargo.nix && nix fmt.
• That commit should include the updated CHANGELOG.md, generated with convco changelog -u $(convco version --bump) > CHANGELOG.md.
  • Unfortunately, after doing this you'll have to update the file to replace HEAD in the URL in the new section heading with v<version>.
• That commit should be tagged with v<version>.
• The commit should be pushed to main, and the tag pushed as well. This will trigger the cargo-dist workflow to build the artifacts and create the release on GitHub.
