我正在尝试从一个文件夹中对创建的文件名列表进行排序。这是代码,因为它是最简单的形式。如果我跑这个,10总是在1而不是9之后。我在看什么。

set composer_list to {"Filename_1", "Filename_2", "Filename_3", "Filename_4", "Filename_5", "Filename_6", "Filename_7", "Filename_8", "Filename_9", "Filename_10", "Filename_11"}
simple_sort(composer_list)


--======================================= Sorting Handler =====================================
on simple_sort(my_list)
    set the index_list to {}
    set the sorted_list to {}
    repeat (the number of items in my_list) times
        set the low_item to ""
        repeat with i from 1 to (number of items in my_list)
            if i is not in the index_list then
                set this_item to item i of my_list as text
                if the low_item is "" then
                    set the low_item to this_item
                    set the low_item_index to i
                else if this_item comes before the low_item then
                    set the low_item to this_item
                    set the low_item_index to i
                end if
            end if
        end repeat
        set the end of sorted_list to the low_item
        set the end of the index_list to the low_item_index
    end repeat
    return the sorted_list
end simple_sort

结果:

{"Filename_1", "Filename_10", "Filename_11", "Filename_2", "Filename_3", "Filename_4", "Filename_5", "Filename_6", "Filename_7", "Filename_8", "Filename_9"}

4 个答案:

答案 0 :(得分:4)

使用:

considering numeric strings
    simple_sort(composer_list)
end considering

结果:

{"Filename_1", "Filename_2", ..., "Filename_9", "Filename_10", "Filename_11"}

答案 1 :(得分:1)

这是因为

"Filename_11" comes before "Filename_2" -- true

如果您填充列表,它应该可以正常工作。

"Filename_11" comes before "Filename_02" -- false

您应该download Nigel Garvey's "A Dose of Sorts"获得最佳排序程序。

答案 2 :(得分:1)

然而,我遇到过这个问题的一个变种:

我有一个带有带连字符的部分和子部分的列表,使用以连字符分隔的数字(section1,section1-3,section1-3-5,section2-0)。使用原始的simple_sort,1-3-5在1-3之前进入。但是,使用“考虑数字字符串”而不是将连字符视为减号,事情都是混乱的。但是,我添加了另一个子程序来预处理比较的字符串,方法是在比较之前删除超出部分:

on removeHyphens(theText)
set AppleScript's text item delimiters to "-"
set theReturn to every text item of theText
set AppleScript's text item delimiters to ""
set theReturn to theReturn as string
return theReturn
end removeHyphens

然后在simple_sort函数中,我将一行更改为:     否则如果removeHyphens(this_item)出现在removeHyphens(low_item)之前,那么

这对于这种特殊情况来说就像是一种魅力。

答案 3 :(得分:0)

怎么样 忽略连字符 ... 结束无视

但最好的答案是:使用Filename_01(前导0填充)
