Beestings
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."
A beesting is escaped with a backslash (\#{
).
Non-Scalar Values
If you try to insert non-scalar values into a string using the beesting syntax, only their types will be printed. For a non-scalar, use the encode()
operator on the value first to turn it into a string.
