Signature

1string->contains(find::string, -case::boolean= ?)

Tests whether a string contains text or a regular expression.

string->contains is called with member syntax on a receiver value. string->contains works with text values. Normalize input at boundaries, escape at output boundaries, and keep encoding calls close to the place where the encoded text is needed.

Parameters

find: Required value of type string. Supply find positionally unless the signature shows a keyword form.
-case: Optional value of type boolean. Supply -case by keyword, keeping the leading hyphen in the call.

Examples

Basic call

1'Lasso'->contains('ass')

The example shows the receiver and result shape. In templates, apply escaping at the final output boundary.
