🎱 Magic 8-Ball

⚠️ Experimental — generated with no human supervision. This realm was produced by an MCP-driven agent to exercise the gno MCP server + tooling and to generate test content for gno compilers, linters and formatters. Not audited. Not for production. Full context & folder README: r/moul/x/daily

A classic Magic 8-Ball as a gno.land realm. Ask a yes/no question and the current block height picks one of the 20 canonical answers — fully deterministic, since there is no true randomness on-chain.

• Ask(cur realm, question string) string — records {caller, question, answer, height} and returns the answer (crossing function; emits a Shaken event).
• Asked() int — how many questions have been asked (read-only).
• Render(path string) string — shows the last answer and a table of recent shakes.

Built for the sapphire testnet (gno 0.9). Example:

gnokey maketx call -pkgpath gno.land/r/moul/x/daily/eightball/v0 \
  -func Ask -args "will this PR pass CI?" ...

What changed in v1

Identical behaviour to v0 apart from rendering, which now goes through p/moul/kit/ui instead of the local shortAddr helper.

One address format. Eleven realms carried their own shortAddr with four different truncation rules, so the same account rendered differently depending on which realm you opened. ui.Addr is that decision made once: 8 leading characters, an ellipsis, 4 trailing, in backticks.

Visible change: addresses now render in monospace.

The rendering change means the output differs from v0, which under this repo's versioning rule is a compatibility change, hence a new version rather than an edit in place. v0 stays live and untouched.

Part of moul/gno-contracts — moul's versioned gno.land contracts. See the repository for the full catalog, build/test tooling, and usage.
