# meow:ui

> Print on-brand, tone-aware status lines from your own programs.

`meow:ui` lets your code emit status lines through meow's terminal engine — the
same Floof aesthetic the CLI uses, with the same graceful degradation to plain text
in pipes and CI.

```typescript theme={null}
import { ui } from "meow:ui";

ui.purr("server started");      // success
ui.pounce("building…");         // progress / work-in-progress
ui.hiss("something went wrong"); // error
```

## API

```typescript theme={null}
function purr(body: string): void;   // success
function hiss(body: string): void;   // error
function pounce(body: string): void; // progress / WIP

const ui: { purr: typeof purr; hiss: typeof hiss; pounce: typeof pounce };
```

You can import the named functions or the `ui` object — they're the same.

```typescript theme={null}
import { purr, hiss, pounce } from "meow:ui";
purr("done");
```

## The three tones

| Function | Tone     | Use for                              |
| -------- | -------- | ------------------------------------ |
| `purr`   | success  | a completed step, a healthy result   |
| `pounce` | progress | work in progress, a step starting    |
| `hiss`   | error    | a failure or warning worth attention |

<Note>
  These names are meow's vocabulary throughout the CLI — a successful `meow install`
  *purrs*, a long step *pounces*, and an error *hisses*. Using `meow:ui` in your own
  scripts keeps their output consistent with the rest of the toolchain, and it
  automatically goes plain (no color, no glyphs) when piped or running under CI.
