Readme View source

Polls & Voting

⚠️ Experimental — generated with no human supervision. This realm was produced automatically by an MCP-driven agent to exercise the gno MCP server and 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

An on-chain poll and voting realm for gno.land (sapphire, gno 0.9). Anyone can create a poll with a question and a comma-separated set of options; every caller address may cast exactly one vote per poll. The realm's Render page lists each poll with its options, live tallies drawn as ▓░ bar charts, per-option percentages, and the total number of votes.

Realm path

gno.land/r/REPLACE_ADDR/polls

Exported transactions

  • CreatePoll(question string, options string) int — create a poll. options is a comma-separated list (blank entries are dropped; at least 2 required). Returns the new poll's id.
  • Vote(pollID int, optionIndex int) — cast one vote for optionIndex on poll pollID. One vote per caller address per poll; a second vote aborts.

Both are gno 0.9 crossing functions (first parameter cur realm); the caller address is read via runtime.PreviousRealm().Address().

Read path

  • Render("") — index of all polls with bar-chart tallies.
  • Render("<id>") — a single poll by id.

Functions 4

func CreatePoll

crossing Action 
1func CreatePoll(cur realm, question string, options string) int
source

CreatePoll registers a new poll. options is a comma-separated list; blank entries are dropped. Returns the new poll's id. Crossing function: an EOA invokes it via MsgCall; another realm via polls.CreatePoll(cross, q, opts).

func PollCount

Action 
1func PollCount() int
source

PollCount returns the number of polls created so far (read-only helper).

func Render 

1func Render(path string) string
source

Render produces the Markdown page for gnoweb. It is NOT a crossing function.

  • "" -> index of all polls
  • "<id>" -> a single poll by id

func Vote

crossing Action 
1func Vote(cur realm, pollID int, optionIndex int)
source

Vote casts one vote for optionIndex on poll pollID. Each caller address may vote at most once per poll. Crossing function.
