使用Apple Script更改字符串中单个单词的大小写

所以我有苹果脚本：

-- Uses the satimage osax
-- Get it at http://www.satimage.fr/software/en/downloads/downloads_companion_osaxen.html

tell application "Music"
    try
        set the_tracks to the selection
        repeat with a_track in the_tracks
            set the_old_name to name of a_track as string
            set the_new_name to titlecase the_old_name
            set the name of a_track to the_new_name
            log the_old_name
            log the_new_name
        end repeat
    on error
        set the_tracks to the selection
        repeat with a_track in the_tracks
            set the_old_name to name of a_track as string
            set the_new_name to titlecase the_old_name
            set the name of a_track to the_new_name
            log the_old_name
            log the_new_name
        end repeat
    end try
end tell

而且我希望能够更改字符串/标题中单个元素的大小写。专门将罗马数字更改为所有大写字母，在本示例中为“ Iv”。并将其更改为“ IV”：

来自：G小调协奏曲格罗索8号，作品 6，《圣诞节协奏曲》：四。维瓦

至：G小调协奏曲格罗索第八号，作品。6，《圣诞节协奏曲》：四。维瓦

任何帮助将不胜感激。谢谢！

此处理程序将所有罗马字符从I替换为IX，后跟一个句点，并使用等价的大写字母代替。它使用了Foundation框架中强大的API

use AppleScript version "2.5"
use framework "Foundation"
use scripting additions

on uppercaseRomanCharacters(theText)
    set cocoaString to current application's NSString's stringWithString:theText
    set romanRange to cocoaString's rangeOfString:"(I{1,3}|IX|IV|VI{0,3})\\." options:1025
    if romanRange's location < cocoaString's |length|() then
        set substring to cocoaString's substringWithRange:romanRange
        return (cocoaString's stringByReplacingCharactersInRange:romanRange withString:(substring's uppercaseString())) as text
    end if
    return theText
end uppercaseRomanCharacters

set theString to "Concerto Grosso No. 8 in G Minor, Op. 6, \"Christmas Concerto\": iv. Vivace"
set newName to uppercaseRomanCharacters(theString)

您可以在循环中使用它

repeat with a_track in the_tracks
    set the_old_name to name of a_track -- as string is redundant
    set the_new_name to my uppercaseRomanCharacters(the_old_name)
    set the name of a_track to the_new_name
    log the_old_name
    log the_new_name
end repeat

处理程序必须位于脚本顶层的某个位置。

注意：1025是选项的整数值 NSCaseInsensitiveSearch | NSRegularExpressionSearch
