使用 AppleScript 从 .txt 文件读取 time/date 变量

Question

我正在尝试使用苹果脚本从 .txt 文件中读取时间/日期变量。根据文件中的时间/日期，我想停止苹果脚本或运行苹果脚本的其余部分。

所以 .txt 文件位于我的桌面上，所以我的苹果脚本如下：

set desktop_folder to "$HOME/Desktop"
set myFile to "timeDate.txt"
do shell script "echo my file contents is:" & myFile
if myFile < 2021-09-25 then
    error number -128
end if

timeDate.txt 文件中的日期较少 2021-09-25 因此它应该停止运行ning 中的其余代码。我不明白为什么代码没有停止。

Answer 1

假设 timeDate.txt 的 content 是格式相同的单个条目，例如2021-09-25 没有尾随 linefeed，然后是下面的 example AppleScript code 做你想做的事。

示例 AppleScript 代码:

set myFile to POSIX path of ¬
    (path to desktop) & "timeDate.txt"

set dateString to read myFile

if dateString < "2021-09-25" then return

如果您运行遇到将 date 与 text/string 进行比较的问题，则使用：

示例 AppleScript 代码:

set thisDate to "2021-09-25"

set myFile to POSIX path of ¬
    (path to desktop) & "timeDate.txt"

set dateString to read myFile

if date dateString < date thisDate then return

Answer 2

要针对特定用户比较没有本地化问题的字符串日期，应首先将它们转换为 日期对象:

-- script: example for comparing string dates
-- assuming the content of text file is a single entry,
-- in the same format as e.g. "2021-09-25"

set comparedDateString to "2021-09-25"
set readDateString to read (choose file of type "txt")

set dateObject to (current date)
set dateObject's year to (text 1 thru 4 of comparedDateString) as integer
set dateObject's day to (text 9 thru 10 of comparedDateString) as integer
set dateObject's month to (text 6 thru 7 of comparedDateString) as integer
set comparedDate to dateObject

set dateObject's year to (text 1 thru 4 of readDateString) as integer
set dateObject's day to (text 9 thru 10 of readDateString) as integer
set dateObject's month to (text 6 thru 7 of readDateString) as integer
set readDate to dateObject

if readDate < comparedDate then error number -128
