Create

Yaml files can be created using the 'new' command. This works in the same way as the write command, but you don't pass in an existing Yaml file.

yaml n <path> <new value>

Creating a simple yaml file

yaml n b.c cat

will output:

b:
  c: cat

Creating using a create script

Create scripts follow the same format as the update scripts.

Given a script create_instructions.yaml of:

b.c: 3
b.e[0].name: Howdy Partner

then

yaml n -s create_instructions.yaml

will output:

b:
  c: 3
  e:
    - name: Howdy Partner

You can also pipe the instructions in:

cat create_instructions.yaml | yaml n -s -

Keys with dots

When specifying a key that has a dot use key lookup indicator.

b:
  foo.bar: 7

yaml r sample.yaml b[foo.bar]

yaml w sample.yaml b[foo.bar] 9

Any valid yaml key can be specified as part of a key lookup.
