Regexp.try_convert

(::Regexp | ::Regexp::_ToRegexp regexp_like) -> ::Regexp

(untyped other) -> ::Regexp?

Regexp.try_convert(object) → regexp or nil

static VALUE
rb_reg_s_try_convert(VALUE dummy, VALUE re)
{
    return rb_check_regexp_type(re);
}

Returns object if it is a regexp:

Example

Regexp.try_convert(/re/) # => /re/

Otherwise if object responds to :to_regexp, calls object.to_regexp and returns the result.

Returns nil if object does not respond to :to_regexp.

Example

Regexp.try_convert('re') # => nil

Raises an exception unless object.to_regexp returns a regexp.
