KRL extended quotes support the beesting operator, making them simple templating systems. Inside an extended quote, expression values can be referenced using the #{<expr>}
syntax. For example, suppose you've stored 10 and 20 in the variables a
and b
:
somevar = << The average of #{a} and #{b} is #{(a+ b)/2} >>; |
The value of somevar
would be "The average of 10 and 20 is 15."
You cannot insert non-scalar values into a string using the beesting syntax. For non-scalars, use the |
Because of a limitation in the parser, you cannot use expressions that contain a right curly brace, }, inside a beesting. The parser simply finds the first right curly brace after the start of the beesting and considers that the end. So, for example, you cannot do this somevar = << This is my first name: #{name{first}} >>; |
