Initializer

init(newRegularExpressionFromPattern:flags:in:)

Creates a JavaScript regular expression value from the specified pattern.

Declaration

init!(newRegularExpressionFromPattern pattern: String!, flags: String!, in context: JSContext!)

Parameters

pattern

A string to be interpreted as a regular expression pattern.

flags

A combination of zero or more single-letter flags specifying search options.

context

The JavaScript context in which to create the value.

Return Value

A new JavaScript regular expression object.

Discussion

Calling this method creates a JavaScript RegExp object, and is equivalent to declaring a regular expression literal (such as /ab+c/i) or calling the RegExp constructor (for example, new RegExp("ab+c", "i")) in JavaScript.

The flags parameter can include any of the following options:

  • g (global match): match all occurrences of the pattern in a string, not just the first.

  • i (ignore case): perform case-insensitive search.

  • m (multiline): treat the ^ and $ regular expression tokens as matching the start or end of any line in a string (as delimited by newline or return characters), not just the start or end of the entire string.
