RingLog

⚠️ 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

A port of Go's container/ring onto gno.land — a fixed-capacity circular message board where new posts automatically evict the oldest once the buffer fills up. Holds the last 16 messages on-chain; no pagination, no clutter.

Realm: gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/ringlog

How it works

The realm maintains a 16-slot ring buffer backed by a fixed-size array. head tracks the next write position; when it wraps past the end it overwrites the oldest slot. Classic O(1) insert, O(n) read — no allocations after init.

Capacity

The buffer holds exactly 16 messages (Cap = 16). Once full, the next Post silently drops the oldest. This mirrors container/ring.Ring.Move with overwrite semantics.

Overview

Package ringlog is an on-chain port of Go's container/ring: a fixed-capacity circular message board where new posts overwrite the oldest entries once full.

Constants 1

const Cap 

1const Cap = 16
source

Cap is the maximum number of messages the ring buffer holds.

Functions 4

func Len

Action 
1func Len() int
source

Len returns the number of messages currently stored.

func Post

Action 
1func Post(msg string)
source

Post adds a message to the ring buffer. Once Cap entries are stored, the oldest entry is overwritten.

func Render 

1func Render(path string) string
source

Render displays the ring buffer as a Markdown page.

func Entries

Action 
1func Entries() []Entry
source

Entries returns all stored messages in chronological order (oldest first).

Types 1

type Entry

struct 
1type Entry struct {
2	Author  address
3	Message string
4	Height  int64
5}
source

Entry is a single posted message.
