2 And and Or

The most primitive combination operators, and and or. In regular expressions and-ing two sub-expressions simply concatenates them.

procedure
(rx/and expr ...+) → string?
expr : string?
procedure
(rx/& expr ...+) → string?
expr : string?

Returns a new expression that concatenates the list of sub-expressions in expr. The function rx/& is simply an alias for rx/and.

Examples:

> (rx/and "a" "b" "cd")
"abcd"
> (rx/& "a" "b" "cd")
"abcd"

value
rx/or-operator : string?

The operator that separates sub-expressions or-ed together.

procedure
(rx/or expr ...+) → string?
expr : string?

Returns a new expression that combines the list of sub-expressions in expr separated by the rx/or-operator.

Example:

> (rx/or "a" "b" "cd")
"a|b|cd"
