yaml-cli

A simple CLI for working with YAML files.

Installation

$ npm install -g yaml-cli

Shell Completion

You can set up shell completion like this:

$ eval $(yaml env -)

Examples

Given the following test.yml file:

foo:
  bar: 7
  baz:
    - 17
    - "hello world"

get

You can get properties:

$ yaml get test.yaml foo.bar
7

or array accessors:

$ yaml test.yaml foo.baz.1
hello world

set

You can set values, too.

$ yaml set test.yaml foo.baz.1 goodbye
foo:
  bar: 7
  baz:
    - 17
    - "goodbye"

template

You can instantiate template files, too. Given the following template:

I would like to say {{foo.baz.1}}

you can instantiate it like this:

$ yaml t test.yaml test.template
I would like to say hello world

json

You can read and write JSON.

To convert from JSON to YAML:

$ yaml json read test.json
foo:
  bar: 7
  baz:
    - 17
    - "hello world"

To convert from YAML to JSON:

$ yaml json write test.yaml
{
  "foo": {
    "bar": 7,
    "baz": [
      17,
      "hello world"
    ]
  }
}

toml

You can read and write TOML, too.

To convert from TOML to YAML:

$ yaml toml read test.toml
foo:
  bar: 7
somename:
  partone:
    one: 7
    two:
      - some string
      - hello world

To convert from YAML to TOML:

$ yaml toml write test-toml.yaml
[foo]
bar = 7
baz = [ "some string", "hello world" ]

You can get more help by just typing yaml.
