This is a simple CLI for converting between MessagePack and JSON. Jump to Installing for installation instructions.
```sh $ # Basic usage: convert a file either direction $ msgpack in.json -o out.msgpack $ msgpack out.msgpack {"name":"messagepack","age":20,"source":"github"}
$ # Pretty formatting $ msgpack out.msgpack --pretty { "name": "messagepack", "age": 20, "source": "github" }
$ # Use stdin input and stdout output. You need to specify the destination type with
$ # --to-msgpack or --to-json (-m or -j)
$ cat in.json | msgpack --to-msgpack | xxd

$ # Use a hex string as input or output $ msgpack --hex -i "82 a7 63 6f 6d 70 61 63 74 c3 a6 73 63 68 65 6d 61 00" --to-json {"compact":true,"schema":0} $ msgpack --hex -i '{"compact":true,"schema":0}' --to-msgpack 82a7636f6d70616374c3a6736368656d6100
$ # And with pretty print: $ msgpack in.json --hex --pretty 83a4 6e61 6d65 ab6d 6573 7361 6765 7061 636b a361 6765 14a6 736f 7572 6365 a667 6974 6875 62 ```
The easiest way to install is to go the [releases] page and download a version.
Alternatively, you can install with Cargo via cargo install msgpack-cli, or
build the source yourself with cargo build --release.
In either of these cases, you will want to make sure that the executables are in
the right path. You can use the provided makefile with make install to set
this up automatically, copy the binary to your preferred location (the manpage
and autocomplete scripts are also included).
See above for usage examples. The command line options are as follows:
``` Usage: msgpack [OPTIONS] [INPUT_FILE]
Arguments: [INPUT_FILE] Specify the input file to read from. If not given, stdin will be used
Options:
-o, --output --hex)
-v, --verbose Turn verbose mode on
-h, --help Print help information (use --help for more detail)
-V, --version Print version information
```
