# `gno.land/r/nym-moultest123/outfmt`

A realm that returns the same data in three shapes, selected by a query
parameter. It exists to show that `Render` is a general response builder and
not only a Markdown emitter.

| path | output |
| --- | --- |
| `""` | an index of the three formats |
| `?fmt=stringer` | human-readable text (the default) |
| `?fmt=json` | a JSON object |
| `?fmt=jsonp` | the same JSON wrapped in `callback(...)` |

Anything else panics.

```bash
gnokey query vm/qrender -data 'gno.land/r/nym-moultest123/outfmt:?fmt=json' \
  -remote https://rpc.gno.land:443
```

The payload is a `Result` (a number, a text, a slice of numbers) drawn from a
package-level `math/rand` source with a fixed seed (`rand.NewPCG(0, 0)`). A
`Render` call is a query, so the draws it makes are never committed.

## Known rough edges

Both are marked `FIXME` in the source and are kept as-is, because they are the
interesting part:

- The query string is split by hand on `?` and `=` instead of going through
  `net/url`, so `?fmt=json&x=1` does not parse.
- Nothing can set a content type. A realm returns a string; the JSON variant is
  JSON only by convention, and the `jsonp` callback name is hardcoded to
  `callback` rather than read from the query.

A realm cannot negotiate content properly today. That limitation is what this
realm documents.
