How to set up notification in os x using applescript
Let's say I have a file sometext.txt
. I want the content of this txt file to be displayed in a notification that I will call using displaynotification
in applescript
.
In other words, I want to be able to:
display notification "File content" with title "Title"
...
How can i do this? Let's assume that sometext.txt
both applescript
are in the same directory.
source to share
TASK
To launch a notification with text from a file that is in the same folder as this script.Note
Save the script before executing, because when the script is not saved, the compiled path points to the "~ / Library / Autosave Information /" folder (where the unsaved scripts are located) or even "/ Applications / Utilities /" (where Script -Editor ).USE
script beeps (when "errBeep" is true) if something was not 100% ok and displays the status in the notification.
- when no text file is found, the script asks for automatic creation.
- If the text file is empty, you get a notification and it opens the file.
- If the text length is longer than
allowedCharactersCount
(default 65), some action may be taken before the notification is triggered.
