YJ - YAML to JSON
Simple command line tool to convert a YAML input file into a JSON output file.
How to, etc.
Built in help
% yj --help
Command line tool that converts YAML to JSON
Usage: yj [OPTIONS] [INPUT]
Arguments:
[INPUT] Input YAML file name. Defaults to stdin
Options:
-c, --compact Use compact formatting for the JSON output
-y, --yaml Format the output as YAML instead of JSON
-j, --json Parse the input as JSON. For most use cases, this
option makes no difference. Valid JSON is valid
YAML, so JSON input will (should?) parse
correctly even when being handled with the YAML
parser. Use this option when you want failure
(instead of weird results) when the input is
invalid JSON
-o, --output <OUTPUT> Output file name for the JSON. Defaults to stdout
-h, --help Print help information
-V, --version Print version information
Installing
Local build and install with cargo
:
$ cargo install yj
Prebuilt binaries are available on Github releases for some common platforms.
On macOS, the prebuilt binary can be installed using
Homebrew. Unfortunately, Homebrew picked up a
different utility with the name yj
after I chose that name here.
So, a simple brew install yj
gets that tool, not this one 😞.
$ brew tap bruceadams/utilities
$ brew install bruceadams/utilities/yj
Alternatively on macOS, you may also install yj
using MacPorts:
$ sudo port selfupdate
$ sudo port install yj
Minimal Docker images are available on Docker Hub:
$ docker pull bruceadams/yj
