# h2i
**h2i** is an interactive HTTP/2 ("h2") console debugger. Miss the good ol'
days of telnetting to your HTTP/1.n servers? We're bringing you
back.
Features:
- send raw HTTP/2 frames
- PING
- SETTINGS
- HEADERS
- etc
- type in HTTP/1.n and have it auto-HPACK/frame-ify it for HTTP/2
- pretty print all received HTTP/2 frames from the peer (including HPACK decoding)
- tab completion of commands, options
Not yet features, but soon:
- unnecessary CONTINUATION frames on short boundaries, to test peer implementations
- request bodies (DATA frames)
- send invalid frames for testing server implementations (supported by underlying Framer)
Later:
- act like a server
## Installation
```
$ go get golang.org/x/net/http2/h2i
$ h2i <host>
```
## Demo
```

## Status
Quick few hour hack. So much yet to do. Feel free to file issues for
bugs or wishlist items, but [@bmizerany](https://github.com/bmizerany/)
and I aren't yet accepting pull requests until things settle down.
