I want to use \n character in multiline string but YAML doesn't allow me to use \n character. How can I use \n character.
My YAML:
treeroot:
branch1:
name: >
hello my friend\n how are you ?
i am fine and you ?\n
yes\nthanks
branch1-1:
name: Node 1-1
branch2:
name: Node 2
branch2-1:
name: Node 2-1
I know, we can use \n character in single line mode but I want use it in multiline.
There is no such thing as 'single-line' mode in YAML. You have scalars that represent strings and they can be plain (no quotes), single and double quoted. Apart from that, in block-style, you have literal and folded style.
Literal and folded style are always multiline (assuming you count the line with the | resp. the >), but the other scalars can be multiline as well. In the later case double new-lines in the string are transformed into newlines and other new-lines into spaces. Since escaping with backslash is only allowed in double quoted strings the following YAML is what you need to use:
treeroot:
branch1:
name: "hello my friend\n how are you ?
i am fine and you ?\n
yes\nthanks"
branch1-1:
name: Node 1-1
branch2:
name: Node 2
branch2-1:
name: Node 2-1
The value for the first key 'name' is the same as if specified as
"hello my friend\n how are you ? i am fine and you ?\n yes\nthanks"
