如何将此 Objective-C 代码写入 AppleScript？

Question

我想实现这个 Objective-C 示例以在 AppleScript 中使用，但我不知道该怎么做。

NSTextCheckingResult *match = [regex firstMatchInString:string
                                            options:0
                                              range:NSMakeRange(0, [string length])];
if (match) {
    NSRange matchRange = [match range];
    NSRange firstHalfRange = [match rangeAtIndex:1];
    NSRange secondHalfRange = [match rangeAtIndex:2];
 }

这是我目前的情况，我不知道如何继续

set theString to "hello world"
set theString2 to "\w+"

set firstMatch to (regex's firstMatchInString:theString options:0 range:{location:0, |length|:(count theString)}) as list  -- do I need to coerce to list?
-- below is obviously wrong
if firstMatch is not missing value then 
    set matchRange = current application's NSRange's range
end if

在这种情况下只存在一个范围（索引=0）。因此，不要请求索引 > 0

处的范围

use AppleScript version "2.4" -- Yosemite or later
use framework "Foundation"
use scripting additions

set searchString to "hello world"
set regexString to "\w+"

set anNSString to current application's NSString's stringWithString:searchString
set stringLength to anNSString's |length|()
set theRegex to current application's NSRegularExpression's regularExpressionWithPattern:regexString options:0 |error|:(missing value)

set match to theRegex's firstMatchInString:anNSString options:0 range:{0, stringLength}

if match is not missing value then
    set matchRange to match's numberOfRanges()
    --> 1, so exists only one range, with index=0
    set matchRange to match's rangeAtIndex:0
end if

set firstMatchString to text ((matchRange's location) + 1) thru ((matchRange's location) + (matchRange's |length|)) of searchString

How do I write this Objective-C code into AppleScript?
