I dealt with a particular use case in my project.
I had to fetch a string with newline characters from a yaml property file.
The string value was something like this:
quote: “I am Bond \n James Bond”
The problem was when I fetched this quote property in my code , it got modified into this :
“I am Bond \n\n James Bond”
I had written the key: value pair like this in the yaml property file :
quote: 'I am Bond\n James Bond'
YAML was appending backslash character to the newline character but I wanted that .
So I researched and found out that YAML doesn’t backslash newline character if you use the character “|” after the key (“quote” in our example) like this :
quote: | I am Bond James Bond
As you see you first enter the character “|”
And then enter a line break
Then you enter the first sentence ( I am Bond)
And then the next sentence in the next line (James Bond)
This is equivalent to the string :
"I am Bond\n James Bond"
This style is called literal style by YAML.
This style treats every character as content and does not escape any restricted characters.
