YAML - Block Sequences
The block sequences of YAML represent a series of nodes. Each item is denoted by a leading “-“ indicator. Note that the “-“ indicator in YAML should be separated from the node with a white space.
The basic representation of block sequence is given below −
block sequence: ··- one↓ - two : three↓
Example
Observe the following examples for a better understanding of block sequences.
Example 1
port: &ports adapter: postgres host: localhost development: database: myapp_development <<: *ports
The output of block sequences in JSON format is given below −
{
"port": {
"adapter": "postgres",
"host": "localhost"
},
"development": {
"database": "myapp_development",
"adapter": "postgres",
"host": "localhost"
}
}
