问题描述
限时送ChatGPT账号..假设我有一个文件 sometext.txt .我希望这个 txt 文件的内容显示在我将使用 applescript 中的 displaynotification 触发的通知中.
Say I have a file sometext.txt . I want the contents of this txt file to show up in the notification which I will trigger using displaynotification in applescript.
换句话说，我希望能够:
In other words I want to be able to:
显示标题为标题"的通知文件内容".
我该怎么做?假设 sometext.txt 和 applescript 文件在同一个目录下.
How can I do it? Assume that sometext.txt and the applescript file are in the same directory.
推荐答案
目标
使用驻留在与此脚本相同的文件夹.
GOAL
To fire a notification with text from a file that resides in the same folder as this script.
注意
在执行之前，请保存脚本，因为当脚本未保存时，组合路径指向~/Library/Autosave Information/"文件夹(未保存脚本所在的位置)甚至指向/Applications/Utilities/"(脚本所在的位置)- 编辑是).
NOTE
Before execution, save the script because when the script is unsaved, the composed path points to the „~/Library/Autosave Information/„ folder (the place where unsaved scripts are) or even to "/Applications/Utilities/" (where Script-Editor is).
用法
脚本发出哔哔声(当 'errBeep' 为真时)如果没有100% 正常并在通知中显示状态.
USAGE
The script beeps (when 'errBeep' is true) if something was not
100% ok and displays the status in a notification.
allowedCharactersCount(默认为 65)，则可以在触发通知之前执行某些操作.
when the text file isn't found the script asks for automatic creation.
if the text file is empty you get notified and it opens the file.
if the length of the text is greater as in allowedCharactersCount (default 65), some action can be performed before firing the notification.
(* *** please customize the appropriate parts *** *)
-- ---------------------------------
-- BEEP when error
-- ---------------------------------
set errBeep to true
--set errBeep to false
-- ---------------------------------
-- file name &
-- number of allowed characters:
-- ---------------------------------
set fileName to "messages.txt"
set allowedCharactersCount to 65
-- ---------------------------------
-- Notification title:
-- ---------------------------------
set notificationTitle to "From: " & fileName
-- ---------------------------------
-- END CUSTOMIZING
-- ---------------------------------
-- ---------------------------------
-- compose file path
-- ---------------------------------
set filePath to my composeFilePath(fileName)
if filePath is "" then
if errBeep then beep
return
end if
-- ---------------------------------
-- check file existence ?
-- ---------------------------------
set filePathExists to my fileExists(filePath)
if not filePathExists then
-- ------------------------------------
-- The file isn't there, ask the user if it should be created (and opened):
-- ------------------------------------
if errBeep then beep
set message to "File " & quoted form of fileName & " at " & return & return & quoted form of filePath & return & return & "is missing."
display dialog message buttons {"Create & Open", "Cancel"} cancel button 2 default button 2 giving up after 20 with title "Where is " & quoted form of fileName & "?" with icon 2
if button returned of the result starts with "Create" then
my readFromFile(filePath) -- this creates the file
tell application "Finder" to open item filePath -- open for edit
end if
return -- we did what we could
end if
-- ---------------------------------------
-- Found the file, now read it:
-- ---------------------------------------
set textFromFile to my readFromFile(filePath)
if textFromFile is not "" then
-- ---------------------------------------------------------
-- Found content, we are ready to fire our notification
-- ---------------------------------------------------------
-- -----------------------------------
-- • but first check length •
-- -----------------------------------
set countCharactersInTextFromFile to count characters in textFromFile -- count includes the "return" characters
if (countCharactersInTextFromFile) is greater than allowedCharactersCount then
-- -----------------------------------
-- • Length is NOT OK
-- More characters as allowed. What to do ? Here, we just beep & change the message and title
-- -----------------------------------
if errBeep then beep
set notificationTitle to "ERROR: " & ((countCharactersInTextFromFile - allowedCharactersCount) as text) & " characters overflow"
set notificationText to (countCharactersInTextFromFile as text) & " characters in textFromFile," & return & (allowedCharactersCount as text) & " characters are allowed."
else
-- -----------------------------------
-- • Length is OK •
-- -----------------------------------
set notificationText to textFromFile
end if
-- ---------------------------------------------------------
-- Fire the notification
-- ---------------------------------------------------------
display notification notificationText with title notificationTitle
-- ---------------------------------------------------------
else
-- ---------------------------------------------------------
-- File is empty! Replace following lines with appropriate action:
-- ---------------------------------------------------------
if errBeep then beep
display notification "*** NO TEXT IN THIS FILE ***" with title "ERROR: EMPTY FILE"
tell application "Finder" to open item filePath -- open for edit
end if
-- ---------------------------------------------------------
-- Sub Routines
-- ---------------------------------------------------------
-- ---------------------------------
-- file existence ?
-- ---------------------------------
on fileExists(filePath)
set filePathExists to false
tell application "Finder"
try
set filePathExists to item filePath exists
end try
end tell
return filePathExists
end fileExists
-- ---------------------------------
-- composeFilePath(fileName)
-- ---------------------------------
on composeFilePath(fileName)
if fileName is "" then return ""
set pathToMe to path to me -- this is the full path to this script
-- get the folder this script is in:
set thisScriptsFolder to ""
tell application "Finder"
try
set thisScriptsFolder to (get container of pathToMe) as text
end try
end tell
if thisScriptsFolder is "" then
return ""
end if
return thisScriptsFolder & fileName -- full path
end composeFilePath
-- ---------------------------------------------------------
-- readFromFile(sourceFile)
-- ---------------------------------------------------------
on readFromFile(sourceFile)
try
set the sourceFile to the sourceFile as string
set the open_sourceFile to open for access file sourceFile
set fileData to read the open_sourceFile
close access the open_sourceFile
return fileData
on error the error_message number the error_number
try
close access file sourceFile
end try
-- display dialog "Error: " & the error_number & ". " & the error_message buttons {"Cancel"} default button 1
return ""
end try
end readFromFile
这里是简短版本:
set fileName to "messages.txt"
set filePath to my composeFilePath(fileName)
display notification my readFromFile(filePath) with title "From: " & fileName
on readFromFile(sourceFile)
try
set the sourceFile to the sourceFile as string
set the open_sourceFile to open for access file sourceFile
set fileData to read the open_sourceFile
close access the open_sourceFile
return fileData
on error the error_message number the error_number
try
close access file sourceFile
end try
return ""
end try
end readFromFile
on composeFilePath(fileName)
if fileName is "" then return ""
set pathToMe to path to me -- this is the full path to this script
-- get the folder this script is in:
set thisScriptsFolder to ""
tell application "Finder"
try
set thisScriptsFolder to (get container of pathToMe) as text
end try
end tell
if thisScriptsFolder is "" then
return ""
end if
return thisScriptsFolder & fileName -- full path
end composeFilePath
