# Microblog Wall

> ⚠️ **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:

A public, append-only microblog for gno.land. Anyone can post a short message
(up to 280 bytes); each post records the caller's address and the block height
at which it was made. The `Render` view shows the wall newest-first, 20 posts
per page, with total count and prev/next pagination driven by the render path.

- **Realm path:** `gno.land/r/REPLACE_ADDR/microblog`
- **Gno version:** 0.9 (sapphire)

## API

- `Post(cur realm, msg string)` — crossing tx. Panics if `msg` is empty or
  longer than 280 bytes. Stores `{author, msg, height}`.
- `Count() int` — total number of posts.
- `Render(path string) string` — Markdown wall, newest-first, paginated.

## Example calls

Post a message (crossing call via `gnokey`):

```sh
gnokey maketx call \
  -pkgpath "gno.land/r/REPLACE_ADDR/microblog" \
  -func Post \
  -args "gm gno.land 👋" \
  -gas-fee 1000000ugnot -gas-wanted 2000000 \
  -broadcast -chainid sapphire-1 -remote <rpc> mykey
```

View the wall in gnoweb:

```
https://gno.land/r/REPLACE_ADDR/microblog          # page 1 (newest 20)
https://gno.land/r/REPLACE_ADDR/microblog:?page=2  # older posts
https://gno.land/r/REPLACE_ADDR/microblog:/2       # same page, path form
```

From another realm:

```go
import "gno.land/r/REPLACE_ADDR/microblog"

func Shout(cur realm) {
    microblog.Post(cross(cur), "posted from another realm")
}
```
