AppleScript allows you to run shell commands with do shell script. It's easy to assign a variable to an output of such command.
set theResult to do shell script "echo everything"
>> theResult = "everything"
On macOS you also can run Javascript code in Terminal with osascript:
osascript -l JavaScript << EOF
console.log('everything');
EOF
>> everything
However, if you execute this piece from AppleScript, you get nothing:
set theResult to do shell script "osascript -l JavaScript << EOF
console.log('everything');
EOF"
>> theResult = ""
I also tried to assign a shell variable to the osascript output and to print it with echo. Again, works in Terminal:
theString=$(osascript -l JavaScript << EOF
console.log('everything');
EOF
)
echo $theString"
>> everything
But it still does not work when executed via do shell script:
set theResult to do shell script "theString=$(osascript -l JavaScript << EOF
console.log('everything');
EOF
)
echo $theString"
>> theResult = ""
Why is this happening? How to make it work?
I'll appretiate your help.
My goal is to be able to do some text processing with Javascript within an AppleScript script.
I'm not interested in putting Javascript code into external .js file, I prefer to keep it in place.
