TOML

Decode from TOML. Note that yq does not yet support outputting in TOML format (and therefore it cannot roundtrip)

Parse: Simple

Given a sample.toml file of:

toml

A = "hello"
B = 12

then

bash

yq -oy '.' sample.toml

will output

yaml

A: hello
B: 12

Parse: Deep paths

Given a sample.toml file of:

toml

person.name = "hello"
person.address = "12 cat st"

then

bash

yq -oy '.' sample.toml

will output

yaml

person:
  name: hello
  address: 12 cat st

Encode: Scalar

Given a sample.toml file of:

toml

person.name = "hello"
person.address = "12 cat st"

then

bash

yq '.person.name' sample.toml

will output

yaml

hello

Parse: inline table

Given a sample.toml file of:

toml

name = { first = "Tom", last = "Preston-Werner" }

then

bash

yq -oy '.' sample.toml

will output

yaml

name:
  first: Tom
  last: Preston-Werner

Parse: Array Table

Given a sample.toml file of:

toml


[owner.contact]
name = "Tom Preston-Werner"
age = 36

[[owner.addresses]]
street = "first street"
suburb = "ok"

[[owner.addresses]]
street = "second street"
suburb = "nice"

then

bash

yq -oy '.' sample.toml

will output

yaml

owner:
  contact:
    name: Tom Preston-Werner
    age: 36
  addresses:
    - street: first street
      suburb: ok
    - street: second street
      suburb: nice

Parse: Array of Array Table

Given a sample.toml file of:

toml


[[fruits]]
name = "apple"
[[fruits.varieties]]  # nested array of tables
name = "red delicious"

then

bash

yq -oy '.' sample.toml

will output

yaml

fruits:
  - name: apple
    varieties:
      - name: red delicious

Parse: Empty Table

Given a sample.toml file of:

toml


[dependencies]

then

bash

yq -oy '.' sample.toml

will output

yaml

dependencies: {}

Roundtrip: inline table attribute

Given a sample.toml file of:

toml

name = { first = "Tom", last = "Preston-Werner" }

then

bash

yq '.' sample.toml

will output

yaml

name = { first = "Tom", last = "Preston-Werner" }

Roundtrip: table section

Given a sample.toml file of:

toml

[owner.contact]
name = "Tom"
age = 36

then

bash

yq '.' sample.toml

will output

yaml

[owner.contact]
name = "Tom"
age = 36

Roundtrip: array of tables

Given a sample.toml file of:

toml

[[fruits]]
name = "apple"
[[fruits.varieties]]
name = "red delicious"

then

bash

yq '.' sample.toml

will output

yaml

[[fruits]]
name = "apple"
[[fruits.varieties]]
name = "red delicious"

Roundtrip: arrays and scalars

Given a sample.toml file of:

toml

A = ["hello", ["world", "again"]]
B = 12

then

bash

yq '.' sample.toml

will output

yaml

A = ["hello", ["world", "again"]]
B = 12

Roundtrip: simple

Given a sample.toml file of:

toml

A = "hello"
B = 12

then

bash

yq '.' sample.toml

will output

yaml

A = "hello"
B = 12

Roundtrip: deep paths

Given a sample.toml file of:

toml

[person]
name = "hello"
address = "12 cat st"

then

bash

yq '.' sample.toml

will output

yaml

[person]
name = "hello"
address = "12 cat st"

Roundtrip: empty array

Given a sample.toml file of:

toml

A = []

then

bash

yq '.' sample.toml

will output

yaml

A = []

Roundtrip: sample table

Given a sample.toml file of:

toml

var = "x"

[owner.contact]
name = "Tom Preston-Werner"
age = 36

then

bash

yq '.' sample.toml

will output

yaml

var = "x"

[owner.contact]
name = "Tom Preston-Werner"
age = 36

Roundtrip: empty table

Given a sample.toml file of:

toml

[dependencies]

then

bash

yq '.' sample.toml

will output

yaml

[dependencies]

Roundtrip: comments

Given a sample.toml file of:

toml

# This is a comment
A = "hello"  # inline comment
B = 12

# Table comment
[person]
name = "Tom"  # name comment

then

bash

yq '.' sample.toml

will output

yaml

# This is a comment
A = "hello"  # inline comment
B = 12

# Table comment
[person]
name = "Tom"  # name comment

Roundtrip: sample from web

Given a sample.toml file of:

toml

# This is a TOML document
title = "TOML Example"

[owner]
name = "Tom Preston-Werner"
dob = 1979-05-27T07:32:00-08:00

[database]
enabled = true
ports = [8000, 8001, 8002]
data = [["delta", "phi"], [3.14]]
temp_targets = { cpu = 79.5, case = 72.0 }

# [servers] yq can't do this one yet
[servers.alpha]
ip = "10.0.0.1"
role = "frontend"

[servers.beta]
ip = "10.0.0.2"
role = "backend"

then

bash

yq '.' sample.toml

will output

yaml

# This is a TOML document
title = "TOML Example"

[owner]
name = "Tom Preston-Werner"
dob = 1979-05-27T07:32:00-08:00

[database]
enabled = true
ports = [8000, 8001, 8002]
data = [["delta", "phi"], [3.14]]
temp_targets = { cpu = 79.5, case = 72.0 }

# [servers] yq can't do this one yet
[servers.alpha]
ip = "10.0.0.1"
role = "frontend"

[servers.beta]
ip = "10.0.0.2"
role = "backend"

Encode: Simple mapping produces table section

Given a sample.yml file of:

yaml

arg:
  hello: foo

then

bash

yq -o toml '.' sample.yml

will output

toml

[arg]
hello = "foo"
