Regexp#timeout

() -> ::Float?

rxp.timeout → float or nil

static VALUE
rb_reg_timeout_get(VALUE re)
{
    rb_reg_check(re);
    double d = hrtime2double(RREGEXP_PTR(re)->timelimit);
    if (d == 0.0) return Qnil;
    return DBL2NUM(d);
}

It returns the timeout interval for Regexp matching in second. nil means no default timeout configuration.

This configuration is per-object. The global configuration set by Regexp.timeout= is ignored if per-object configuration is set.

Example

re = Regexp.new("^a*b?a*$", timeout: 1)
re.timeout               #=> 1.0
re =~ "a" * 100000 + "x" #=> regexp match timeout (RuntimeError)
