# {u,}varint-{en,de}code -- Variable integer encoding/decoding tools

This repository provides command-line tools to interact with the

varint/uvarint format, as used by

[Protocol Buffer](https://developers.google.com/protocol-buffers/docs/overview)

and Go's [encoding/binary](http://golang.org/pkg/encoding/binary/)

package.

The `{u,}varint-encode` tools take integers on the command line and

output binary. Use `--` to pass negative integers.

The `{u,}varint-decode` tools read standard input and output integers,

one per line.

Examples:

``` console

$ uvarint-encode 42 | hexdump -x

0000000    002a                                                        

0000001

$ varint-encode -- -42 | hexdump -x

0000000    0053                                                        

0000001

$ uvarint-encode 42 | uvarint-decode

42

$ varint-encode 42 | varint-decode

42

$ varint-encode -- -42 | varint-decode

-42

```
